Description

TECHNICAL FIELD The present invention relates to a bill counting machine adapted to make a denomination determination by sucking bills loaded in a holder onto a suction shaft and flipping the bills one by one. Is.

"Prior Art" Conventionally, as this type of bill counting machine, a "paper sheet counting machine" shown in Japanese Patent Laid-Open No. 57-787 and a "paper sheet counting machine" shown in Japanese Utility Model Laid-Open No. 58-129558. There is a paper sheet confirmation device in.

The former "paper sheet counter" determines the denomination by adhering the paper sheets (banknotes) loaded in the holder to the suction shaft and flipping the sheets one by one, and the denomination is counted. That is,
If it is different from the first denomination), or if the denomination cannot be determined, the separator of the so-called batch device is still located on the holder side and is counted. By pressing it against the surface of the banknote that is not in the open state, the turning operation by the suction shaft is interrupted, and at the time of this interruption, the banknote that is judged to be a different denomination or the abnormal judgment banknote (both are collectively called abnormal banknote) You can check it.

On the other hand, the latter "paper sheet confirmation device in paper sheet counter"
The same as the former "paper sheet counter", the so-called batch device separator is used to confirm the abnormal banknotes by interrupting the subsequent flipping operation by the suction shaft for banknotes. In the apparatus, a mirror is provided so that the last bill flipped off can be confirmed from the operation side so that the confirmation operation at the time of interruption can be easily performed.

[Problems to be Solved by the Invention] That is, in the banknote counter configured as described above, when an abnormal banknote is detected, subsequent banknotes are flipped by the residual vacuum pressure in the suction shaft that inertially rotates. However, because it is forcibly blocked by the separator, for example, in the case of bills that are easily damaged due to scratches, such as circulation tickets, between the part pressed by the separator and the part adsorbed by the suction shaft There was a problem that it might break in between.

In addition, when an abnormal bill is detected, the counting is stopped halfway to check, but since the abnormal bill will be put together at the end of the counted bills, in the former bill counting machine, the operator has already counted. It is necessary to check only the last abnormal banknote from the banknote of No. by hand, so the operability at that time is poor, and in the latter banknote counter, it is easy to confirm that point. However, in reality, it is not possible to install a large mirror due to the arrangement of the optical system for discrimination, or the separator of the batch device when detecting abnormal banknotes, and as a result, the ease of confirmation is greatly improved. I couldn't.

Furthermore, even though the conventional method has poor operability,
If different denominations were detected, and if a discrimination error occurred, it was possible to continue counting for a while by checking the last bill that was flipped, but only in the case of double suction detection, for example, bills Except when it can be confirmed that two or more sheets were adhered with tape etc., it is confirmed whether it is really double suction or whether only partial stain on one banknote is detected. I could not do it, and I had to restart the counting from the beginning.

The present invention has been made in view of the above circumstances,
While not requiring a so-called batch device having a separator, the operation of turning over the bills by the suction shaft is interrupted when abnormal bills are detected, and the rotating cylinder in which the suction shaft is arranged is suddenly stopped so that the bills are not counted by the suction shaft. Both the counted bills and the counted bills are stopped at an intermediate separation position, and by confirming the denomination of the abnormal bill when the separation stop is interrupted, the bill flipping determination operation from the separation stop interruption time is automatically restarted. It is an object of the present invention to provide a bill counting machine capable of

Further, in the second invention, in the first invention, the abnormal banknotes that have been suddenly stopped at the intermediate separation position are automatically transferred to the uncounted banknote side without requiring the operator to confirm the abnormal banknotes. It is an object of the present invention to provide a bill counting machine which can return the bill and then perform the bill flipping determination operation again.

Further, in the third invention, in the second invention, when the banknotes that are automatically returned to the uncounted banknotes side and subjected to the flipping judgment operation again are continuously judged as abnormal banknotes, Stop the retry process again and stop in the separation stop state so that the operator can confirm the abnormal banknotes in the separation stop state, and then restart the bill flipping determination operation from the separation stop interruption point It is an object of the present invention to provide a bill counting machine capable of

Furthermore, in the fourth invention, in the first invention or the third invention, when confirming the abnormal banknote stopped at the intermediate separating position, the denomination information can be input,
Provided is a bill counting machine capable of calculating the total amount of bills loaded in a holder, based on denomination information output during the rolling operation of the suction shaft and denomination information input at the time of interruption. The purpose is to do.

[Means for Solving the Problem] In order to achieve the above object, the first aspect of the present invention is that the banknotes loaded in the holder are attracted to suction shafts that are evenly arranged on the concentric circles of the rotary cylinder, and are turned one by one. While the bill counter is designed to determine the denomination, the surface pattern of the bill is read, and the denomination code of the bill is determined by comparing the surface pattern with prestored reference data. On the other hand, when the abnormal bill is detected, a discrimination control circuit that outputs an error code, and based on the error code output from the discrimination control circuit, in order to interrupt the bill flipping operation by the suction shaft, Abruptly decelerating the rotation and sucking the abnormal bill at the intermediate separation position after the suction shaft releases the abnormal bill from the suction and until the succeeding bills are sucked. A counting motor that stops the uncounted bills and the counted bills apart from each other by the axis, and the presence or absence of abnormality about the abnormal bills stopped by this counting motor at an intermediate separation position apart from both the uncounted bills and the counted bills When the confirmation result of the abnormal bill is input by operating the operation switch and the operation switch for inputting the confirmation result of, the interruption due to the stop of the counting motor is released, and the bill flipping determination from the interruption point is performed. And a counting control circuit for automatically restarting the operation.

The invention according to claim 2 is a bill counting machine configured to make a denomination determination by adsorbing bills loaded in a holder to suction shafts that are evenly arranged on concentric circles of a rotary cylinder and flipping the bills one by one, By reading the surface pattern of a banknote and comparing the surface pattern with prestored reference data, the denomination of this banknote is determined and a denomination code is output, while an error code is output when an abnormal banknote is detected. Based on the control circuit and the error code output from this determination control circuit, in order to interrupt the bill-turning operation by the suction shaft, the rotation of the rotary cylinder is suddenly stopped, and the abnormal bill is sucked by the suction shaft. Counting motor that stops at an intermediate separation position apart from both uncounted banknotes and counted banknotes, and uncounted banknotes and counted banknotes by the counting motor The abnormal banknotes stopped at the intermediate separation position apart from the banknotes are automatically returned to the uncounted banknote side, the interruption due to the stop of the counting motor is released, and the banknote flipping determination operation is automatically restarted again. And a counting control circuit.

According to a third aspect of the present invention, in the counting control circuit according to the second aspect, in the case where the bill subjected to the turning-over determination operation is restarted as the turning-over determination operation, the bill is discriminated as an abnormal bill again. When the abnormal bill is confirmed by operating the operation switch, the interruption due to the stop of the counting motor is released, and the bill flipping determination operation from the interruption point is automatically restarted. It is characterized by.

According to a fourth aspect of the present invention, in the first or third aspect, the operation switch is capable of inputting a denomination code of an abnormal bill, and the denomination code input by the operation switch and the discrimination control circuit are used. It is characterized by having an amount calculation circuit for calculating the total amount of bills loaded in the holder based on the denomination code automatically output.

[Operation] According to the first aspect of the invention, when an abnormal bill is detected, the rotary cylinder in which the suction shaft is arranged is suddenly stopped, and the abnormal bill is separated from the uncounted bill and the counted bill by the suction shaft. When the separation stop is interrupted and the denomination of the abnormal banknote is confirmed when the separation stop is interrupted, the banknote flipping determination operation from the separation stop interrupted time is automatically restarted.

Further, according to the second aspect, when an abnormal bill is detected and suddenly stopped at the intermediate separation position, the abnormal bill is automatically returned to the uncounted bill side, and then the bill is turned off again. The operation is automatically restarted.

Further, according to the third invention, in the second invention, the bill that is first turned over and discriminated during the retry process is:
If it is determined to be an abnormal banknote again, it is stopped in the separation stop state without performing the retry process so that the abnormal banknote in the separation stop state can be confirmed, and when this confirmation is made, the separation stop interruption described above is performed. The bill flipping determination operation from the point in time is automatically restarted.

Further, according to the fourth invention, in the first invention or the third invention, when the denomination of the abnormal banknote stopped at the intermediate separating position is input, the banknote is turned over from the separation stop interruption point. The picking discrimination operation is automatically restarted, and the denomination code entered when entering this denomination,
The total amount of bills loaded in the holder is calculated based on the denomination code that is automatically discriminated and output at the time of counting one by one by the suction shaft.

Then, the light radiated to and transmitted through the banknote Sa is condensed by the condenser lens 39 on the light receiving element 38, and the amount of the light is detected. It is supposed to be done.

That is, when the amount of transmitted light is equal to or larger than a predetermined value, it is determined as normal feeding (single sheet feeding), and when the amount of transmitted light is equal to or less than the predetermined value, double feeding is determined.

Next, a discriminating mechanism for discriminating the denomination and the front / back of the bill S will be described with reference to FIGS. 1 and 2.

The reference numeral 40 in FIG. 2 indicates the frontmost banknote Sb of the uncounted banknotes to be flipped over by the suction shaft 5.

When the time counting is interrupted,
There are ten thousand ticket buttons, five thousand ticket buttons, thousand ticket buttons (this confirmation button is also used to confirm different denominations), etc. for performing denomination confirmation input for bills with abnormal discrimination.

Here, briefly describing the mode, "count addition" is a mode in which the number of banknotes is counted and the count value is accumulated for each counting operation, and "designation (batch)" is For example, the number of banknotes is designated as 50, and when the counting of 50 is completed, the counting is interrupted and the banknote is separated into 50 counted banknotes and uncounted banknotes. (Check) is a mode for confirming whether or not the set number of banknotes is bundled, and further, "Marking" is performed if the result of reconfirmation is correct after reconfirmation of the banknotes. This is a mode in which a seal is stamped from the side or from the bottom, and the "amount calculation" is a mode in which the total amount of bills loaded in the holder and counted is calculated and displayed.

In addition, a plurality of these modes can be set at the same time as long as their functions do not conflict with each other.

By the way, the start switch 52 shown in FIG. 4 is composed of a push button 60 (see FIG. 1) provided in the holder 1 in this embodiment.

The drive signal supplied from the drive circuit 71 to the area sensor 34 is composed of an X-axis drive signal and a Y-axis drive signal. The surface pattern (area data) at a specific position in the area E is read out.

When extracting the surface pattern data in the area E, first, the Y-axis drive signal is output to determine the Y coordinate of the area E, and then the X-axis drive signal is output. The X coordinate of E may be changed in a fixed direction.

That is, the Y coordinate is set to 1 and the data in the area E is read as line data (X, 1) (where X = 1 to X _max ), and the Y coordinate is set to 3 and the line data (X, 3) (however, X = 1 to X _max ) is read, and the plurality of read line data are stored in the RAM 65 and compared with the reference data stored in the ROM 64.

The contents of the program stored in the ROM 47 of the counting control circuit 45 will be described along with the operation of the bill counting machine with reference to the drawings.

It should be noted that FIG. 5 is composed of FIG. 2 of (A) and (B),
Further, FIG. 6 is composed of four figures of (A), (B), (C) and (D).

Further, SN in FIGS. 5 and 6 represents step N in the following description, and in FIG. 9 and FIGS.
Tn indicates the timing Tn in the following description.

(A) Counting control operation 1 (see FIGS. 5 (A) to (B) and FIG. 9) FIG. 5 (A) <Step 1> Power on <Step 2> The holder open position detection sensor 24A is operated. , It is determined whether or not the holder 1 is in the open position. If NO, the holder motor 23 is driven to open to set the holder 1 to the open position (step 3). Go to step 4.

<Step 4> Depending on whether or not there is an output from the rotary cylinder position sensor 18, the suction shaft 5
Is in the standby position (that is, the position where the suction shaft 5 faces the banknote S), and if NO, the counting motor
The suction shaft 5 is set to the standby position by driving 19 in the normal direction (direction at the time of counting) at a low speed (step 5). If YES, the process proceeds to the next step 6.

<Step 6> It is determined whether or not the setting operation of the mode setting switch has been performed. If YES, the modes operated according to various mode setting operations are stored (step 7), and if NO, Proceeds to the next step 8.

<Step 8> It is determined whether or not a start signal (ST) is output from the start switch 52. If NO, the process returns to the step 6, and if YES, the process proceeds to the next step 9 (timing T1 ).

<Step 9> The holder closed position detection sensor 24B is operated to determine whether or not the holder 1 is in the closed position. If NO, the holder motor 23 is driven to be closed and the holder 1 is set to the closed position. If YES (step 10), the process proceeds to the next step 11 (timing T2).

<Step 11> The pump drive signal (PMP) is output and the pump motor 21
Is driven and the solenoid valve drive signal (S
V) is output to the solenoid valve 16 and the exhaust nozzle 14
Switch to the side.

<Step 12> Depending on whether there is an output from the rotary cylinder position sensor 18, the suction shaft 5
Is at the start position (that is, the position immediately before the opening 10 of the suction shaft 5 faces the banknote S and the inside of the suction shaft 5 is shut off from the vacuum pump 8). NO
In case of, the counting motor low speed reverse rotation drive signal (CMD-R)
Is output, the counting motor 19 is driven at a low speed in the reverse direction (direction opposite to that at the time of counting) to set the suction shaft 5 to the start position (step 13), and if YES, the process proceeds to the next step 14. (Timing T3).

<Step 14> Waiting for the pressure determination signal (VSW) to be output, that is, for the vacuum pressure in the suction pipe line 7 to rise to a predetermined value, the process proceeds to the next step 15 (timing T4). ).

<Step 15> When the pressure determination signal (VSW) is output, the counter motor forward rotation drive signal (CMD-FF) is output, and high-speed rotation of the rotary cylinder 3 and the suction shaft 5 is started.

FIG. 5 (B) <Step 16> The suction shaft 5 adsorbs the banknotes S one by one and turns them off, and in parallel with this turning operation, the rotary cylinder position sensor
Each time 18 generates a signal (SNS), a counting signal (CNT) is output to count the bill S (timing T6 to timing).
Tm).

Further, in the mode for discriminating the bill S, the trigger signal (TRG) for taking out the detection data of the area sensor 42 is output at almost the same timing to discriminate the bill S.

<Step 17> Since the uncounted banknotes S on the holder 1 are lost and the suction operation of the banknotes S by the suction shaft 5 cannot be performed, the vacuum pressure in the suction pipe line 7 drops and the pressure sensor 11 is turned off.
When the pressure determination signal (VSW) is not output, or as will be described later, the operation of turning over the set number of banknotes S by the suction shaft 5 in the batch mode is completed and the rotary cylinder 3
If the subsequent flipping operation of the banknote S is stopped due to the sudden stop, it is determined that the normal end is YES and the process proceeds to the next step 18, otherwise the process proceeds to step 30 as NO.

As will be described later, the detection of the residual error and the number-of-mismatch error is a judgment made after the normal end, and therefore these are included in the normal end.

<Step 18> The output of the count motor forward drive signal (CMD-FF) is stopped, the count motor brake signal (CM-BRK) is output instead, and the count motor 19 is suddenly stopped (timing Tm
+1).

At the same time, the output of the pump drive signal (PMP) and solenoid valve drive signal (SV) is stopped, and the pump motor 21
And the solenoid valve 16 is switched to the discharge port 15 side.

<Step 19> It is determined whether or not the batch mode is ON. If YES, the process proceeds to step 20, and if NO, the process proceeds to step 22.

<Step 20> As will be described later, it is determined whether or not the batch operation is normally completed. If YES, the process proceeds to step 22, and if NO, the process proceeds to step 21.

<Step 21> Since the batch operation is not normally performed and it is unknown whether the set number of banknotes and the uncounted banknotes have been reliably separated, an alarm signal (a signal for driving a buzzer or the like) indicating an abnormality is output.

<Step 22> As will be described later, the holder 1 is automatically operated according to the processing mode or by operating the clear button (clear switch).
Is judged whether or not the open signal of
If NO, the process returns to step 2 of FIG. 5 (A) (timing Tn), and if NO, waits at step 22.

When returning to step 2, the open position setting operation of the holder 1 and the standby position setting operation of the suction shaft 5 are performed as described above, and the counting is immediately started by the next start signal (step 8). You will have to wait in a state where you can do it.

<Step 30> When it is not determined in step 17 that the normal rotation has ended, in this step 30, the rotary cylinder 3 suddenly stops due to an error detection (discrimination abnormality, different denomination, front / back mismatch, double suction detection) described later. Then, the suction shaft 5 is used to prevent the bills from being turned over, and it is determined whether or not the counting is interrupted and the process is abnormally terminated. If YES, the process proceeds to step 31 and NO.
In case of, it returns to step 16.

Then, as described above, as long as the pressure determination signal (VSW) is output (NO) or the batch operation is not performed, the loop between steps 16, 17, and 30 will be described later. The counting operation is performed as follows.

<Step 31> By determining that the abnormal end, the counting motor 19 is stopped suddenly, the pump motor 21 is stopped,
The operation of stopping the separation of the abnormal bill is performed.

Note that the separation stop operation at this time is the basis of the batch operation described later, and therefore, steps from step 31 described later will be performed.
The processes up to 35 will be described in detail according to the state explanatory diagrams shown in FIGS. 11 and 12 and the time chart shown in FIG.

That is, as shown in FIG. 11, by the timing T81 when the rotary cylinder position sensor 18 detects the operating piece 17 provided around the rotary cylinder 3 and the rising of the rotary cylinder position sensor output signal (SNS) occurs. , The discrimination process for the banknote Sa is completed,
It is assumed that the bill Sa is determined to be an abnormal bill.

Then, at this timing T81, as shown in FIG.
The count motor brake signal (BRK) is given instead of the count motor drive signal (CMD normal rotation), and the rotation of the rotary cylinder 3 on which the suction shaft 5 is arranged is rapidly decelerated.

After that, at timing T81, the operation piece 17 detected by the rotary cylinder position sensor 18 is no longer detected by the rotary cylinder position sensor 18, that is, the rotary cylinder position sensor output signal (SNS) falls. Within the rotation range (the rotation range from the position shown in FIG. 11 to the position shown in FIG. 12), for example, at timing T82 shown in FIG. 13, the rotation of the rotary cylinder 3 completely stops.

Then, at this timing T82, the abnormal bill Sa is
As shown in Fig. 12, uncounted banknotes (the frontmost banknote is
(Denoted by Sb), the counted bills Sc and Sd are both stopped at the intermediate separating position.

The banknote Sb immediately after the abnormal banknote Sa that has been separated and stopped
Due to the residual vacuum pressure in the suction shaft 5, at the time of the separation stop operation, as shown in FIG.
Although it is in a state of being sucked and bent by the banknote, the banknote Sb immediately returns in the direction of the arrow due to the strength (elasticity) of the waist of the banknote Sb itself.

<Step 32> It is determined whether or not the abnormal banknote Sa is reliably separated and stopped at the intermediate position as shown in FIG. 12 by the sudden stop of the counting motor 19, and if YES, the process proceeds to the next step 33, If NO, go to step 40.

In this case, the rotation cylinder position sensor output signal (SNS) is output until the timing when the rotation of the rotation cylinder is completely stopped (for example, within a certain time from timing T81 to timing T83).
Whether or not the separation stop is surely possible can be determined by whether or not the ON state is maintained.

<Step 33> It is determined whether or not the abnormal banknote Sa that has been separated and stopped is re-counted and continuously determined as an abnormal banknote by a retry process described later, and if NO, to the next step 34. If YES, that is, if the same bill is continuously judged as an abnormal bill, the process proceeds to step 36.

<Step 34> The abnormal banknote Sa separated and stopped at the intermediate separation position shown in FIG.
In order to perform the retry process for automatically re-determining the above, the counting motor 19 is reversely driven at a low speed (step 35), and the suction shaft 5 two before is set to the start position, and then the step of FIG. 5 (A). Returning to 11, the discrimination operation for the abnormal bill Sa is performed again.

That is, at timing T83, the counting motor drive signal (CMD low speed reverse rotation) is applied instead of the counting motor brake signal (BRK) to start the reverse rotation of the counting motor 19 at low speed.

At the timing T84 during this reverse rotation operation, the suction shaft 5 located between the abnormal bill Sa and the uncounted bill Sb in FIG. 12 is substantially at the starting position (almost directly facing the uncounted bill Sb in FIG. 11). The position of the suction shaft 5 is reversed), and the abnormal bill Sa
Returns to the position of the banknote Sa shown in FIG. 11, and further at timing T85, the abnormal banknote Sa and the counted banknote S are shown in FIG.
Abnormal bills that have been separated and stopped by reversing the suction shaft 5 located between c and Sd to the start position shown in FIG.
Sa becomes with uncounted bill Sb.

Then, at this timing T85, instead of the counting motor drive signal (CMD low speed reverse rotation), the counting motor brake signal (BRK) is given again to stop at this position.

And when returning to step 11 of FIG. 5 (A),
When the pump motor 21 is driven again and the pressure determination signal (VSW) is output again (timing T86), the counting motor drive signal (C
(MD forward rotation) is given to automatically restart the discriminating operation for the abnormal bill Sa (after timing T87).

Next, the abnormal banknotes Sa that have been separated and separated are re-counted by the immediately preceding retry process, and then again in succession.
The process in the case of being determined as will be described based on steps 36 to 41.

The processing from step 36 to step 41 will be described in detail with reference to the state explanatory diagrams shown in FIGS. 11 and 12 and the time chart shown in FIG.

<Step 36> As shown in FIG. 12, the abnormal banknotes Sa which are continuously judged to be abnormal in step 33 are separated and stopped at a position relatively close to the counted banknotes Sc and Sd of the abnormal banknotes Sa. Since it is in such a state, it may be difficult for the operator to perform any visual confirmation.

In order to solve this, it is preferable to reverse the suction shaft 5 (rotating cylinder 3) from the position of the separation stop state of FIG. 12 to the position of the banknote Sa shown in FIG. 1, and return the suction shaft 5 to the standby position. The process is performed between step 36 and step 39.

That is, at timing T103, the counting motor drive signal (CMD) is output in the reverse rotation direction until the suction shaft 5 returns to the start position shown in FIG. 11 (while this step 36 is NO),
When the counting motor 19 is driven in reverse at a low speed (step 37) and the suction shaft 5 is returned to the start position (this step 36 is YES).
In the case of: at timing T104), the process proceeds to the next step 38.

<Step 38> After the suction shaft 5 is returned to the starting position shown in FIG. 11, this time, the count motor drive signal (CMD) is output in the forward rotation direction (timing T105), and the suction shaft 5 is moved to the first position. 1 is set to the standby position (while this step 38 is NO), the counting motor 19 is driven in the normal direction at a low speed (step 39), and when it is set to the standby position (YES in this step 38). Case: Timing T106), the process proceeds to the next Step 40.

<Step 40> If the abnormal abnormal banknote Sa is detected abnormally through steps 33 to 39, or if the abnormal termination of the abnormal banknote Sa is unsuccessfully stopped in step 32,
The operator visually confirms the denomination of the abnormal bill Sa.

In this case, as shown in FIG. 1, the abnormal bill Sa is set at a position where visual confirmation is easy, so that the operator can promptly perform confirmation.

Then, by operating the confirmation switch, the continuation count is determined to be YES, and the process proceeds to step 11.

After that, the pump motor 21 is started to drive, and the pressure determination signal (VSW) is output (step 14 YES), so that the turning-over determination operation of the uncounted banknote Sb is restarted.

On the other hand, in this step 40, while the confirmation step is not operated (while the continuous counting is NO), it is determined in step 41 whether or not the clear button is operated, and in the case of YES when the clear button is operated, Step 41 to Step 2 above
As with step 2, you will return to step 2.
When 1 is NO, the process stands by in the loop of step 40 and step 41.

Next, the details of the counting process flow in the CPU 49 will be described with reference to FIGS. 6A to 6D, and the details of the determination process flow in the CPU 66 will be described with reference to FIGS. 7 and 8.
It will be described with reference to the drawings.

(B) Counting control operation 2 (see FIGS. 6 (A) to (D)) First, the control at the time of counting will be described focusing on the flow in FIG. 6 (A).

FIG. 6 (A) <Step 100> Start <Step 101> The pump motor 21 is started to be driven.

<Step 102> Whether the suction shaft 5 is at the start position (SNS is OFF) is determined by the ON-OFF state of the rotary cylinder position sensor output signal (SNS). If NO, the counting motor Reverse 19 at a low speed to set the suction shaft 5 to the start position (step 103).
In the case of ES, the process proceeds to the next step 104.

<Step 104> It is determined whether or not the detection mode switch 53 is ON, that is, whether or not it is necessary to read the pattern on the bill surface. If YES, the determination ON signal and the front / back mode signal (however, , Only when the front / back mode switch 54 is ON, the same applies hereinafter to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow), and the double feed detection lamp 37 and the projector 40 are turned on. (Step 10
Five).

Further, when the detection mode switch 53 is OFF, it is determined that only counting is performed, and the process proceeds to the next step 106.

<Step 106> This step is performed until the vacuum pump 18 is driven and the suction shaft 5 is set to the start position, so that the vacuum pressure in the suction shaft 5 rises and the pressure determination signal (VSW) is output. 106
Wait at.

<Step 107> When the pressure determination signal (VSW) is output, the counting motor 19 starts to rotate at high speed in the forward direction.

<Step 108> The rotary cylinder position sensor output signal (SNS) in the OFF state turns ON.
Detects whether or not it is the rising time to enter the state, YES
In case of, proceed to the next step 109.

<Step 109> The trigger signal (T
RG) is output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow).

<Step 110> The ON-OFF state of the rotary cylinder position sensor output signal (SNS) is detected. If ON (YES), the process proceeds to the next step 111, and if NO, the process proceeds to step 116.

<Step 111> It is judged whether or not the pressure judgment signal (VSW) is ON. If it is ON (YES), proceed to the next Step 112, and if OFF (ON), proceed to Step 180. Discriminate OF
Discrimination control circuit 46 for F signal (discrimination routine shown in FIG. 7)
Lamp 37 (shown by an arrow) and for driving the counting motor 19, the pump motor 21, and the double feed detection, the projector.
After the lighting of 40 is stopped (step 181), the process proceeds to step 182 in FIG.

<Step 112> It is determined whether or not the detection mode switch 53 is ON. If YES, the process proceeds to the next step 113, and if NO, the process proceeds to step 114.

<Step 113> As will be described later, when a different denomination is detected, when the front and back discrepancies are detected in the front and back discrimination mode, when it is determined that the discrimination abnormality does not coincide with all the reference patterns, or two When heavy adsorption is detected, the discrimination control circuit 46 (7th
It is determined whether or not there is an input of an error signal (indicated by an arrow) output from the discrimination routine shown in the figure). , Step of FIG. 6 (C)
If it is NO that the error signal is not input, the process proceeds to the next step 114.

<Step 114> It is determined whether or not the batch mode is ON. If YES, the process proceeds to the next step 115, and if NO, the process returns to step 110.

<Step 115> The number of bills to be flipped (count value) is compared with a preset setting value to determine whether the two values match, and it is determined that the count value has not reached the set value. If NO, the process returns to step 110. If YES, it is determined that the count value has reached the set value, and if YES, the process proceeds to step 120 of FIG. 6 (B) to perform so-called batch processing. .

In this way, the rotary cylinder position sensor output signal (SN
S) is in the ON state, the pressure determination signal (VSW) is ON, there is no error signal input, and the agreement in the batch mode is not obtained, the routine of step 110 to step 115 is continued, When the rotary cylinder position sensor output signal (SNS) is turned off in 110, the process proceeds to the next step 116.

<Step 116> Similar to Step 111, it is determined whether or not the pressure determination signal (VSW) is ON. If ON (YES), the process proceeds to the next Step 117, and OFF (NO) In this case, the process proceeds to step 118 and the determination OFF signal is output to the determination control circuit 46 (7th
(Determination routine shown in the figure) (indicated by an arrow), and driving of the counting motor 19, the pump motor 21, and the double feed detection lamp 37 and the light projector 40 are stopped (step 18).
After 1), the process for normal termination is performed, and therefore the process proceeds to step 182 in FIG. 6D.

<Step 117> Similar to step 108, it is detected whether or not the rotary cylinder position sensor output signal (SNS) in the OFF state has reached the ON state, and if YES, the next step 118
If NO, the process returns to step 116 if NO.

<Step 118> A counter CNT that outputs a trigger signal (TRG) to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow) and counts the number of flipped bills as in step 109. Is incremented by 1 (step 119) and the process returns to step 110.

Next, the control at the time of batch processing (when step 115 is YES) will be described centering on the flow in FIG. 6 (B).

FIG. 6 (B) <Step 120> Similar to Step 180, the determination OFF signal is applied to the determination control circuit.
Output to 46 (discrimination routine shown in FIG. 7) (indicated by arrow), and proceed to the next step 121.

It should be noted that, in the description of the steps after step 121 for performing the batch processing associated with the matching of the number of sheets, details will be described with reference to the state explanatory view shown in FIGS. 11 and 12 and the time chart shown in FIG. explain.

First, the situation at the time when the count value and the set value match will be described.

If the set number of banknotes to be batch processed is the banknote Sa shown in FIG. 11, an operating piece provided around the rotary cylinder 3
When the rotating cylinder position sensor 18 detects 17 and the rotating cylinder position sensor output signal (SNS) rises, the counter C
NT is incremented by 1 (see steps 117 to 119 above:
At timing Tm in FIG. 9), the number of sheets coincides with each other (step 115).

As described above, if the rotation of the rotary cylinder 3 is suddenly stopped at this point, as in the case of detecting the abnormal bill, the set number of bills Sa will stop at the intermediate separation position shown in FIG. Immediately, the rotation of the rotary cylinder 3 is continued without stopping suddenly and the rotation position is monitored.

<Step 121> Monitor the ON-OFF state of the rotary cylinder position sensor output signal (SNS), and if it is OFF (YES), proceed to the next Step 122 and turn it ON.
In the case of (NO), the process waits in this step 121.

Note that when set to OFF, the set number of banknotes Sa is the first
This corresponds to when the position shown in FIG. 2 is reached, and if there is a set number plus the first bill, the plus first bill will be in the position indicated by bill Sb in FIG. You will be turned over.

<Step 122> Monitor the ON-OFF status of the rotary cylinder position sensor output signal (SNS), and if it is ON (YES), proceed to the next Step 123 and turn it OFF.
In the case of (NO), the process stands by in this step 122.

Note that when set to ON, the set number of banknotes Sa is the 11th
This corresponds to when the position indicated by the banknote Sc is reached, which coincides with the timing indicated by the timing Tm + 1 in FIG. 9, and when the set number of sheets plus the first banknote exists, as described above. The first banknote is the banknote Sa shown in FIG.
You will be turned to the position indicated by.

<Step 123> Then, at this timing Tm + 1, as shown in FIG. 9, the counting motor brake signal (CM-BRK) is applied instead of the counting motor forward drive signal (CMD-FF), and the suction shaft 5 The rotation of the rotary cylinder 3 in which is arranged is rapidly decelerated, and the pump motor 21 is driven and the double feed detection lamp is detected.
37, the lighting of the projector 40 is stopped.

<Step 124> The ON / OFF state of the rotary cylinder position sensor output signal (SNS) is monitored, and in the loop with the next step 125, the rotary cylinder 3 is detected while the rotary cylinder position sensor output signal (SNS) remains in the ON state. Determine whether it has stopped.

That is, when the rotary cylinder position sensor output signal (SNS) is in the ON state (when step 124 is YES), in step 125, it is determined whether or not the ON state has continued for a certain period of time,
If NO has not elapsed for a certain period of time, the process waits in a loop with step 124, and if YES for a certain period of time, it is determined that the rotary cylinder 3 can be stopped in the ON state, and the next step Proceed to 126 (timing Tm + 2 in FIG. 9).

On the other hand, in the loop from step 124 to step 125,
If the ON state is turned OFF in the middle without elapse of a certain time (NO in step 124), the process proceeds to step 133.

In addition, when the rotary cylinder 3 can be stopped while the rotary cylinder position sensor output signal (SNS) remains ON, the set number of banknotes Sa
Corresponds to the time when the position indicated by the bill Sc (Sd) in FIG. 12 is reached, and similarly to the above, when there is the set number of bills plus the first bill, the plus first bill The bill will be turned up to the intermediate separating position indicated by bill Sa in FIG.

Furthermore, the set number of sheets plus the second banknote Sb shown in FIG. 12 is attracted to the suction shaft 5 as shown in FIG. 12 for a short time due to the residual vacuum pressure in the suction shaft 5. Although it is in a folded state, the strength of the banknote Sb itself causes it to immediately return in the direction of the arrow.

<Step 126> For batch processing, it is necessary to clearly divide the set number of banknotes and the uncounted number of banknotes, and the set number of banknotes stopped at the intermediate separation position plus the first banknote Sa ( 12th
(Figure) is returned to the uncounted bill Sb side.

That is, at this step 126, at timing Tm + 3, the counting motor 19 is started at low speed by giving the counting motor low speed reverse rotation signal (CMD-R) instead of the counting motor brake signal (CM-BRK).

Note that this reverse rotation processing is performed by the rotary cylinder position sensor output signal (SN
It is controlled by monitoring the ON-OFF status of S).

<Step 127> Monitor the ON-OFF status of the rotary cylinder position sensor output signal (SNS), and if it is OFF (YES), proceed to the next Step 128 and turn it ON.
In the case of (NO), it waits in this step 127.

In addition, when it is turned off, the set number of bills shown in FIG. 12 bill Sa plus the first bill is returned to the position shown in FIG. 11 bill Sa.

At this time, the set number of banknotes Sc (Sd) are not bisected by the suction shaft 5 which is reversed as shown in FIG. 11 banknote Sc depending on the strength of the banknote itself. Absent.

<Step 128> Monitor the ON-OFF status of the rotary cylinder position sensor output signal (SNS), and if ON (YES), proceed to the next step 129 and turn OFF.
In the case of (NO), the process waits at this step 128.

In addition, when it is turned ON, it corresponds to when the set number of sheets returned to the position shown in FIG. 11 banknote Sa plus the first banknote is returned to the position shown in FIG. 12 banknote Sb. And this coincides with the timing indicated by the timing Tm + 4 in FIG.

At this timing Tm + 4, even if the rotation of the rotary cylinder 3 is stopped, due to the rigidity of the banknote Sb itself, it becomes together with other uncounted banknotes as shown by the arrow in FIG. 12, but more reliably. The rotation of the rotary cylinder 3 is continued for a little longer so that the rotary cylinder 3 can work together.

<Step 129> Monitor the ON-OFF status of the rotary cylinder position sensor output signal (SNS), and if it is OFF (YES), proceed to the next step 130 and turn it ON.
In the case of (NO), this step 129 waits.

In addition, when it is turned off, the set number of sheets returned to the position shown in FIG. 12 banknote Sb plus the first banknote corresponds to the time returned to the position shown in FIG. 11 banknote Sb. And this coincides with the timing indicated by the timing Tm + 5 in FIG.

<Step 130> At this timing Tm + 5, the batch processing ends, and the counting motor brake signal (CM-BRK) is applied for a short time instead of the counting motor low-speed reverse rotation signal (CMD-R), and the counting motor 1
Stop 9

<Step 131> As described above, it is output whether or not the clear operation for taking out the set number of banknotes subjected to the batch processing from the holder 1 has been performed, or when the batch processing described later has failed. It is determined whether or not the clear operation for taking out the bills on the holder 1 is performed while releasing the alarm, and if YES, the process proceeds to the next step 132.

<Step 132> Open signal for holder 1 (see step 22 above)
Is output, and this flow ends.

On the other hand, in step 124, the ON state of the rotary cylinder position sensor output signal (SNS) does not continue for a certain period of time and turns OFF midway.
The situation will be described in detail.

First, when the rotary cylinder position sensor output signal (SNS) is turned off in the middle, and when the set number of sheets plus the first bill exists, the plus first bill is shown in FIG. bill
This indicates that the sheet has been turned over to the position indicated by the bill Sc or the position indicated by the bill Sd in FIG. 11 beyond the intermediate separation position indicated by Sa, which indicates failure of the batch processing.

It should be noted that if the plus first bill is stopped at the position shown in Fig. 11 bill Sc, it may be possible to carry out the above-mentioned returning process, but depending on the strength of the waist of the bill, etc. Since it may be possible to move to the position indicated by the bill Sb in FIG. 11, when the rotary cylinder position sensor output signal (SNS) is turned off midway, it is decided to proceed to the next step 133.

By the way, if there is the set number of bills plus the first bill, the batch processing will fail, but if the number of bills loaded into the holder 1 coincides with the set number of bills, the rotary cylinder 3 suddenly stops. Even if it fails to overrun, it cannot be said that the batch process has failed.

That is, the next step 133 is a step of determining whether or not the set number of sheets plus the first bill is present.

<Step 133> As described in step 120, when the set number of banknotes (denoted by banknote Sa in FIG. 11) are counted and the number of coins coincides, the set number of coins plus 1 A trigger signal (TRG) for discrimination has already been output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) for the eye bill (denoted by bill Sb in FIG. 11) (step 11 above).
8 reference: indicated by arrow: timing Tm in FIG. 9).

This trigger signal (TRG), as described in more detail below.
Is output, the determination result for the set number of banknotes shown in FIG. 11 banknote Sa is output (however, only in the case of abnormality) and the set number of banknotes shown in FIG. 11 banknote Sb plus the first banknote When the surface pattern of the bill is read and whether the bill is present or not is determined based on the read data, the end signal is output only when the bill is not present.

Therefore, in this step 133, the discrimination control circuit 46
Further, it is determined whether or not the end signal is output as indicated by the arrow. If YES, the process proceeds to step 131 without outputting an alarm, and if NO, the process proceeds to the next step 134.

In addition, in order to output the end signal, it is necessary to be in the detection mode as described above, and in the case of simple calculation,
All batches fail and are processed.

<Step 134> If the batch processing fails as described above, or if an abnormal banknote is detected and cannot be separated into the intermediate separation position shown in FIG. 12 banknote Sa, as will be described later, the batch is defective. An alarm is output to notify the operator by an abnormal lamp or a buzzer, and the operation proceeds to step 131.

Next, the control at the time of detecting an abnormal bill (in the case of step 113YES) will be described focusing on the flow of FIG. 6 (C).

Note that the intermediate separation stop operation during the retry processing or confirmation processing associated with the detection of abnormal banknotes (almost equal to the batch operation)
In the description of the steps after step 135, the description will be made with reference to the state explanatory diagrams shown in FIGS. 11 and 12 and the time charts shown in FIGS. 13 and 14.

First, assume that an abnormal bill (denoted by bill Sa in FIG. 11) is detected at timing T81 in FIG.

FIG. 6 (C) <Step 135> Similar to Steps 180 and 120, a discrimination OFF signal is output to the discrimination control circuit 46 (discrimination routine shown in FIG. 7) (indicated by an arrow), and the next step Continue to 136.

<Step 136> Then, at this timing T81, as shown in FIG.
The count motor brake signal (BRK) is given instead of the count motor signal (CMD normal rotation), the rotation of the rotary cylinder 3 on which the suction shaft 5 is arranged is rapidly reduced, and the pump motor 21
Driving, the double feed detection lamp 37, and the lighting of the projector 40 are stopped.

<Step 137> Similar to Steps 124 to 125, the ON-OFF state of the rotary cylinder position sensor output signal (SNS) is monitored, and in the loop with the next Step 138, the rotary cylinder position sensor output signal (SN) is detected.
It is determined whether the rotary cylinder 3 has stopped while S) remains ON.

That is, when the rotary cylinder position sensor output signal (SNS) is in the ON state (when step 137 is YES), in step 138, it is determined whether or not the ON state has continued for a certain period of time,
If NO has not elapsed for a certain period of time, the process waits in a loop with step 137, and if YES for a certain period of time, it is determined that the rotary cylinder 3 can be stopped in the ON state, and the next step Proceed to 139 (timing T82 in FIG. 13).

On the other hand, in the loop from step 137 to step 138,
If the ON state is turned OFF during a certain period of time (step 137 is NO), the above step 124
As in the case of NO, step 134 shown in FIG. 6 (B).
The abnormal banknotes are detected, but a batch failure alarm indicating that the banknotes could not be separated to the intermediate separation position shown in FIG. 12 banknote Sa is output, and the operator is notified by an abnormal lamp or buzzer, and the step described above is performed. Continue to 131.

In addition, when the rotary cylinder 3 can be stopped while the rotary cylinder position sensor output signal (SNS) remains in the ON state, the abnormal bill Sa is
As shown in Fig. 12, both counted bills Sc and Sd are uncounted bills.
It also indicates that Sb has been reliably stopped in a separated state.

Note that the bill Sb next to the abnormal bill Sa shown in FIG. 12 is attracted to the suction shaft 5 and bent as shown in FIG. 12 due to the residual vacuum pressure in the suction shaft 5 for a short time. However, due to the strength of the waist of the banknote Sb itself, it will immediately return in the direction of the arrow.

<Step 139> In step 119, the count value of the counter CNT counted is compared with the value of the counter R · CNT set at the time of retry (reset to 0 at the beginning of the count start), and the discrepancy NO In the case of, the process proceeds to the next step 140, the count value of the counter CNT is set in the counter R · CNT, and the process proceeds to step 141.
Proceed to 7.

That is, for example, when the 45th bill is determined to be an abnormal bill for the first time, the values of both counters are CNT = 45 and R · CNT = 0.
Then, when the values of both counters do not match, it is judged that the bill is an abnormal bill for the first time, and the retry process is performed.・ Because it is set as CNT = 45,
The values of both counters match and the retry process is not performed.

<Step 141> As described in step 34, in order to perform the retry process for automatically re-determining the abnormal bill Sa separated and stopped at the position shown in FIG. 12, the counting motor 19 is reversely driven at a low speed ( FIG. 13 timing T83) In order to set the two previous suction shafts to the start position, the rotary cylinder position sensor output signal (SN
(S) ON-OFF state, the following steps 142 to 144
To monitor at.

<Step 142> That is, in this step 142, the ON-OFF state of the rotary cylinder position sensor output signal (SNS) is monitored and turned OFF (YE
If it is S), the process proceeds to the next step 143, and if it is ON (NO), it waits in this step 142.

Note that the OFF time corresponds to when the abnormal bill shown in FIG. 12 bill Sa is returned to the position shown in FIG. 11 bill Sa, which is the timing T84 in FIG.
Coincides with the timing indicated by.

<Step 143> Monitor the ON-OFF status of the rotary cylinder position sensor output signal (SNS), and if it is ON (YES), proceed to the next Step 144 and turn OFF.
In the case of (NO), this step 143 waits.

In addition, when it is turned on, the abnormal banknote returned to the position shown in FIG. 11 banknote Sa corresponds to the time returned to the position shown in FIG. 12 banknote Sb.

<Step 144> Monitor the ON-OFF state of the rotary cylinder position sensor output signal (SNS), and if it is OFF (YES), proceed to the next step 145 and turn it ON.
In the case of (NO), it waits in this step 144.

In addition, when it is turned off, the abnormal banknote returned to the position shown in FIG. 12 banknote Sb corresponds to the time returned to the position shown in FIG. 11 banknote Sb, which is This coincides with the timing indicated by timing T855 in FIG.

<Step 145> At this timing T85, the returning process of the abnormal bill Sa is completed, and instead of the count motor drive signal (CMD low speed reverse rotation), the count motor brake signal (BRK) is given for a short time to stop the count motor 19.

<Step 146> The abnormal banknote indicated by banknote Sa in FIG. 12 is the banknote Sb in FIG.
As shown in, when the uncounted banknotes are combined, the count value of the counter CNT is corrected, and 1 is subtracted.

That is, the abnormal banknote Sa has already been counted by the counter CNT in step 119, and when it is combined with the uncounted banknote, it is double counted at the time of retry counting, so in this step 146. The count value is corrected by subtracting 1.

Then, returning to step 101 shown in FIG. 6 (A), the pump motor 21 is started to be driven, and in step 105, the determination ON signal (and the front / back mode signal) is output again and the double feed detection is performed. Lamp 37 and floodlight 40
Lights up.

Then, in step 106, the output of the pressure determination signal (VSW) is detected (see timing T8 in FIG. 13).
6), start rotating the counting motor 19 at high speed in the forward direction,
Below, when the rotary cylinder position sensor output signal (SNS) turns on, the trigger signal (TRG) and count signal (C
NT) is output, and the bill flipping denomination determination operation from the point of interruption is automatically restarted.

On the other hand, as described in step 139, the case where the same banknote is continuously discriminated as an abnormal banknote will be described.

First, it is assumed that an abnormal bill (denoted by bill Sa in FIG. 11) is detected at timing T101 in FIG. 14 and the abnormal bill Sa is stopped in a separated state at timing T102 as shown in FIG.

<Step 147> The abnormal bill Sa is, as shown in FIG. 12, counted bills Sc,
Since it is stopped at a position relatively close to the Sd side,
It may be difficult for the operator to perform visual confirmation to some extent. From step 147 onward, in order to eliminate this, from the position in the separation stop state shown in FIG. 12 to the position of the position banknote Sa shown in FIG. The rotary cylinder 3 is reversed.

That is, at timing T103 in FIG. 14, the counting motor
A counter motor drive signal (CMD low speed reverse rotation) is applied to 19 instead of the count motor brake signal (BRK), and the rotary cylinder 3 is reversely driven at low speed.

<Step 148> Monitor the ON-OFF status of the rotary cylinder position sensor output signal (SNS), and if it is OFF (YES), proceed to the next step 149 to turn it ON.
In the case of (NO), this step 148 waits.

In addition, when OFF, the abnormal bill shown in FIG. 12 bill Sa corresponds to when it is returned to the position shown in FIG. 11 bill Sa, this is at timing T104 in FIG. It matches the timing shown.

<Step 149> At this timing T104, the output of the count motor drive signal (CMD low speed reverse rotation) to the count motor 19 is stopped,
Instead, the counting motor brake signal (BRK) is given for a short time to stop the reverse rotation operation of the rotary cylinder 3, and at timing T105, the counting motor 19 receives the counting motor drive signal (BRK) instead of the counting motor brake signal (BRK). (CMD low speed forward rotation) is applied to drive the rotary cylinder 3 forward at low speed.

<Step 150> The ON-OFF state of the rotary cylinder position sensor output signal (SNS) is monitored, and when it is ON (YES), the process proceeds to the next step 151 (thinking to timing T106), and if it is OFF (NO) Wait at this step 150.

<Step 151> At timing T106, the output of the counting motor drive signal (CMD low speed forward rotation) to the counting motor 19 is stopped, and instead, the counting motor brake signal (BRK) is given for a short time to cause the rotating cylinder 3 to rotate normally. This is equivalent to the time when the abnormal bill indicated by the bill Sa in FIG. 11 is moved from this position to the position indicated by the bill Sa in FIG. 1 after being stopped.

Then, in this state, the operator confirms what is determined as the abnormal bill Sa.

<Step 152> Determine whether the current mode is the amount calculation mode,
If YES, the process proceeds to the next step 153, and if NO, the process proceeds to step 165.

<Step 153> In the interrupted state in which the abnormal banknote Sa is separated and stopped at the intermediate separation position (position where both uncounted banknote Sb and counted banknotes Sc and Sd are separated) shown in FIG. Banknote Sa
Visually confirm the denomination of, the denomination button corresponding to the denomination of this abnormal banknote Sa, in this step 153, it is determined whether the million button is operated, if YES, the determination process flow described later. Similar to step 216 in step 1, set a code representing all the vouchers (set a flag: step 154) and NO.
In case of, proceed to the next step 155.

<Step 155> As in the case of Step 153, it is determined whether or not the 5000-ticket button is operated, and if YES, the code representing the 5000-ticket is set (step 156), and if NO, the next step. Proceed to 157.

<Step 157> As in the case of steps 153 and 155, it is determined whether or not the ticket button is operated. If YES, a code representing the ticket is set (step 158), and if NO, the next step. Proceed to 159.

<Step 159> In any of the above steps 153, 155, 157, it is determined whether or not the denomination code for the abnormal bill Sa has been set, and if YES, the process proceeds to the next step 160, and if NO, Proceed to step 161.

<Step 160> After setting the denomination code for the abnormal banknote Sa, it is determined whether or not the confirmation button for confirming this has been operated. If YES, the process proceeds to step 163, and if NO, the process proceeds to the next step 161. move on.

<Step 161> If the abnormal banknote Sa visually confirmed is a banknote in a double suction state, or if it is a paper sheet such as a receipt sandwiched between the banknotes, it should be removed. A clear operation is required, and in this step 161, it is determined whether or not the clear button has been operated as in the case of step 131. If YES, the procedure proceeds to step 162 to end the counting operation, and if NO, Returns to step 153 so that the denomination code for the abnormal bill Sa can be input.

<Step 162> Similar to step 132, the open signal to the holder 1 (see step 22) is output, and this flow is ended.

<Step 163> On the other hand, in step 160, when the denomination code for the abnormal bill Sa is set and its confirmation operation is performed, the set denomination code is output as in step 216 in the determination processing flow described later. Then, in the next step 164, it is cleared to input the denomination at the time of detecting the next abnormal bill, and similarly to step 146, the process returns to step 101 shown in FIG.
Start driving 1 and in step 105, determine again.
The signal (and the front / back mode signal) is output, and the double feed detection lamp 37 and the projector 40 are turned on.

Then, in step 106, when the output of the pressure determination signal (VSW) is detected, the counting motor 19 starts to rotate at high speed in the forward rotation direction, and thereafter, the rotary cylinder position set output signal (SNS) is turned on. At the time of rising, the trigger signal (TRG) and the counting signal (CNT) are output, and the bill flipping denomination determination operation from the interruption point is automatically restarted.

<Step 165> In step 152, when the current mode is other than the amount calculation mode, that is, when an abnormal bill is detected in the different denomination detection mode, the abnormal bill is already flipped and counted. It is confirmed that it is the same denomination by checking whether it is the same denomination of the bill
If YES, the process returns to step 101 shown in FIG. 6 (A) in the same manner as in steps 146 and 163, and thereafter, the bill flipping denomination determination operation from the interruption point is automatically performed in the same manner. When NO, the process proceeds to the next step 166.

<Step 166> Similar to steps 131 and 161, it is determined whether or not the clear button has been operated, and it is confirmed that the abnormal banknote is a different denomination banknote and the clear button has been operated, in the case of YES, In step 162, the open signal for the holder 1 (see step 22) is output, the flow is terminated, and if NO, the process returns to step 165 and step 1
Wait in the loop from 65 to step 166.

In the flow shown in FIG. 6C, it is explained that only confirmation input for one banknote can be made.
Therefore, in the case of the double suction detection, it may be considered that only the clear operation should be processed, but in the case of the present invention, the double suction banknote also has the intermediate separation shown in FIG. 12 or 1. Since it can be set to the position where it is separated and stopped, it is possible to confirm the number (and denomination structure) of the double-adsorbed banknotes.
The number data (and the denomination code corresponding to the number) can be input.

In that case, the double suction banknote Sa itself has already counter CNT
Since the number of sheets is counted as 1, the data of the number of sheets to be inputted is subtracted by 1 and added to the counter CNT.

Further, all the denomination codes that are input are valid and are used as they are for counting the amount of money.

Next, as described in step 111 or step 116 of FIG. 6A, the case where the pressure determination signal (VSW) is turned off during the turning-over counting operation by the suction shaft 5 is shown in FIG. Description will be made based on the flow shown in FIG.

It should be noted that this flow shows the flow at the end of counting in the modes other than the batch mode described above.

<Step 182> It is determined whether or not the detection mode switch 53 is ON. If YES, the process proceeds to the next step 183, and if NO, the process proceeds to step 188.

<Step 183> When the end signal is not input (indicated by an arrow) from the discrimination control circuit 46 (discrimination routine shown in FIG. 7) for a fixed time (step 184) as in the case of step 133. , For example, when the bills to be counted are set but the suction shaft 5 does not suck the bills, a flag indicating a residual error is set in a predetermined area of the storage unit (RAM48). After that (step 185), the process proceeds to the next step 186.

If an end signal is input, step 188
Proceed to.

<Step 186> Similar to step 131, step 161, or step 166, it is determined whether or not the clear button has been operated, and the clear button is pressed to reset the residual error or to reset the mismatch error described later. In the case of operated YES, the routine proceeds to step 187, where the open signal for the holder 1 (see step 22 above) is output, and this flow is ended, and in the case of NO, it stands by in this step 186.

<Step 188> When the current mode is not the detection mode in the step 182, or when the input of the end signal is confirmed in the step 183, an error occurs in counting and discriminating the bills loaded in the holder 1. If the process is completed without occurrence of, the process determines whether the mode setting is the number-of-sheets check mode. If YES, the process proceeds to the next step 189, and if NO, the process proceeds to step 193.

<Step 189> It is determined whether or not the number of bills counted as described above matches a preset number of coins, and the numbers match.
If YES, the process proceeds to the next step 190, and if NO, a flag indicating a mismatch error is set in a predetermined area of the storage unit (RAM 48) (step 191).
Then, the process proceeds to step 186.

<Step 190> Furthermore, it is determined whether or not the mode setting is set to the marking mode. If YES, the marking solenoid 30C (or 31C) is operated to mark the band seal (Step 19).
2) If NO, proceed to the next step 193.

<Step 193> It is determined whether or not the mode setting is set to the addition mode. If YES, the counting result of the previously counted banknotes is added, and the addition result is stored in the storage unit (RAM48). Then, it is displayed (step 194), and if NO, the process proceeds to the next step 195.

<Step 195> It is determined whether or not the mode setting is set to the amount counting mode. If YES, the total amount of bills counted is displayed (step 1969). If NO, if NO. In step 187, the open signal to the holder 1 (see step 22) is output, and this flow is ended.

In the amount counting mode, the total amount is displayed in step 196. However, when the counter CNT in step 119 shown in FIG. It is also possible to calculate and display the total amount of money based on the denomination code output in 216.

Next, referring to FIGS. 7 and 8, the discrimination control circuit 46
The contents of the program stored in the ROM 64 will be described.

FIG. 7 <Step 200> Discrimination routine start <Step 201> It is determined whether or not a trigger signal (TRG) (indicated by an arrow) is input from the counting routine, and if YES, the process proceeds to the next step 202.

<Step 202> It is determined whether or not a discrimination ON signal (indicated by an arrow) is input from the counting routine. If NO, the process returns to step 201, and if YES, the analog switch 80 shown in FIG.
Is selected, the output of the light receiving element 38 of the double feed detection sensor is addressed via the amplifier 78 and the A / D converter 73 and stored in the RAM 65 (step 203), and then the process proceeds to step 204.

<Step 204> Based on the error code set in step 215, step 223, and step 232, which will be described later, it is determined whether or not different denominations are mixed, front and back do not match, and there is a discrimination error (abnormal banknote is mixed). , YES outputs an error signal and error code and displays the error content on the display 63
(Step 205), the process returns to step 201.

The error signal output at step 205 is supplied to step 113 of the counting routine of FIG. 6 (A) as indicated by the arrow.

Further, in the case of NO where there is no mixing of different denominations, inconsistency between front and back, and discrimination abnormality, the process proceeds to the next step 206.

It should be noted that when the first trigger signal (TRG) is output, the steps 215, 222, and 232 have not been passed, and no determination has been made, so the first step 204 is always NO and the process proceeds to step 206.

<Step 206> Based on the detection data captured from the light receiving element 38 of the double feed detection sensor in Step 203 and the double comparison level which is the determination reference set in Step 218 (described later),
It is determined whether or not the bill has been double-sucked, and if YES, an error signal and an error code are output, the error content is displayed on the display unit 63 (step 207), and then the process returns to step 201.

The error signal output at step 207 is supplied to step 113 of the counting routine of FIG. 6A as indicated by the arrow.

On the other hand, in the case of NO which is determined not to cause double adsorption, the process proceeds to the next step 208.

As in step 204, the first trigger signal (TR
G) At the time of output, the banknote Sa for which double suction is to be determined does not exist at the position shown in FIG. 1, and the double comparison level serving as the reference is not set, so the first step 206 is always NO. Then, it proceeds to step 208.

<Step 208> The analog switch 79 shown in FIG. 4 is selected and the output of the area sensor 34 is transferred to the RAM 65 via the amplifier 72 and the A / D converter 73.
Area data (data on the N line) in the area E is stored by storing the data in the area.

The area data is taken in based on the flow shown in FIG.

That is, when a capture signal is output (step 30
After setting Y to 0 and X to 0 in (0) (step 301),
Proceed to next step 302.

Then, in this step 302, it is judged whether or not the output of the necessary N line data (area data) is completed, and if YES, a discrimination start signal is output (step 303), and FIG. Return to the main routine of.

If NO in step 302, steps 304 to 311 are looped until the designated N-line data is output in step 312, and as described above at the time when the data is output. Go to step 303.

Then, when the line-by-line acquisition of the area data is completed in this way, the process proceeds to the next step 209 shown in FIG.

<Step 209> It is determined whether or not the data captured in step 208 is of a level having no pattern (that is, whether or not the surface 1b of the holder 1 is a black pattern), and YES
In the case of (no data), the end signal is output (step 210) and the process returns to step 201.

It should be noted that the end signal output in step 210 is, as indicated by an arrow, step 133 in FIG.
It is supplied to step 183 in FIG.

If the acquired area data is of a level having a pattern (NO), the process proceeds to the next step 211.

<Step 211> It is determined whether or not the setting mode is set to the amount calculation mode, and if YES, it is determined which of the denominations the banknotes are loaded into the holder 1 one by one. Therefore, the process proceeds to step 213, and if NO, proceeds to the next step 212.

<Step 212> It is determined whether or not the first bill is attracted by the suction shaft 5, and if YES, the process proceeds to step 213, and NO.
If yes, then go to step 230.

<Step 213> Based on the area data of the first bill taken in step 208, a total of 12 patterns (4 × L pattern) of the current three denominations (L denominations) stored in the ROM 64 The data (for one denomination, there are four patterns of front and back) is compared, and the process proceeds to the next step 214.

<Step 214> As a result of comparing the area data of the first bill and the reference data of 12 patterns, it is determined whether or not there is a matched pattern. If NO, it is impossible to discriminate the abnormal bill. Then, a flag indicating a discrimination abnormality is set in a predetermined area of the storage unit (RAM65) (step 215), and the step 201
Return to.

If there is a matching pattern (YES), the storage unit (R
AM65) sets a flag indicating that the banknote identified in the predetermined area is one of the three denominations (step
216), and after setting a flag indicating the front and back of the bill (step 217), based on the discriminated denomination and front and back information, the double comparison level, which is the discrimination criterion of double suction stored in the ROM 64. Is set in the storage unit (RAM65) (step 218), and the process proceeds to step 219.

As described above, in the amount calculation mode, the counting control circuit 45 automatically calculates the total amount of the flipped banknotes at any time based on the denomination code output in step 216, and this calculation The results are displayed on the display 63 as described above.
Can be displayed at any time.

<Step 230> On the other hand, when it is determined in step 212 that the bill sucked by the suction shaft 5 is not the first bill, the area data of the bill taken in step 208 and the ROM 64 are stored. Only the reference data of four patterns of the front and back, which are the specific denominations set (the denomination set in step 216), are compared and the process proceeds to the next step 231.

<Step 231> As a result of comparing the area data of the banknote with the reference data of four patterns, it is determined whether or not there is a matching pattern. If NO, this banknote is a different denomination banknote (strictly speaking, The storage section (RAM6)
A flag indicating a different denomination is set in a predetermined area of 5) (step 232), and the process returns to step 201.

If there is a matching pattern (YES), as described above, a flag indicating the front and back of the bill is set in a predetermined area of the storage unit (RAM65) (step 217), and further in step 218 the storage unit (RAM65). ), A double comparison level, which is a criterion for determining the double suction of the bill, is set in the predetermined area, and the process proceeds to step 219.

<Step 219> It is determined whether the front / back mode switch 54 is ON. If NO, the process returns to step 201, and if YES, the process proceeds to the next step 220.

<Step 220> It is determined whether or not this bill is the first bill, and if NO, the process proceeds to step 222, and if YES, the next step 22
Go to 1.

<Step 221> The front and back codes of the first bill set in step 217 are set in the storage unit (RAM65) as front and back reference data, and thereafter, the front and back of the bill are determined based on the front and back reference data (step 222).

<Step 222> Front and back cords set in step 217 and step 2
By comparing with the front and back reference data set in 21, it is determined whether or not the second and subsequent bills match the front and back of the first bill, and if they match (YES), Step 201
If there is a mismatch (NO), go to the next step 22.
In 3, a flag indicating that the front and back sides do not match is set in a predetermined area of the storage unit (RAM 65), the process returns to step 201, and steps 201 to 232 described above are repeated again.

The timing for fetching the above-mentioned trigger signal (TRG), double data, etc. is shown in the timing chart of FIG.

When these trigger signals (TRG), the timing of capturing double data, and the steps in FIG. 7 are associated with each other, the determination trigger signal corresponds to step 201, and the dual data capture timing corresponds to step 203. Hereinafter, the error check timing corresponds to step 204, the double check timing corresponds to step 206, the area data acquisition timing corresponds to step 208, the end check timing corresponds to step 209, and the discrimination processing timing corresponds to step 211 to step Corresponding to 214 and step 230, step 231, in addition, denomination, front and back,
Double comparison level, error set timing, step
216 to step 218, step 215, step 223, and step 232 correspond to each.

In this determination processing flow, when the second and subsequent denominations are determined in a mode other than the amount calculation mode, that is, when steps 211 and 212 are both NO, only the different denomination code can be output as the error code. However, immediately before step 232 of this determination processing flow, the remaining eight patterns are compared to determine whether or not there is a matching pattern, and if there is a matching pattern, it is left as it is. Go to step 232 and set a different denomination code,
On the contrary, if there is no matching pattern, it is possible to proceed to step 215 and set the discrimination abnormality code.

In the above embodiment, the retry process of automatically returning the abnormal banknotes to the uncounted banknotes side and performing the determination operation again when the abnormal banknotes are detected is always executed. In step 7, it is possible to set a mode as to whether or not retry processing is performed,
Between step 32 and step 33, and between step 138 and step 139, a step for determining whether or not a mode for performing retry processing is set is added, and if the mode is set, step 33 or step It is also possible to proceed to step 139 and proceed to step 40 or step 147 if the other mode is not set.

"Effects of the Invention" As described above in detail, while reading the surface pattern of a banknote, determining the denomination of the banknote and outputting a denomination code, an error code is output when an abnormal banknote is detected, and the suction shaft Suddenly stop the arranged rotating cylinder to stop the abnormal banknotes at the intermediate separation position apart from both the uncounted banknotes and the counted banknotes by the suction shaft, and confirm the abnormal banknotes when the separation stop is interrupted. When the abnormal bill is confirmed, the interruption state in which the flipping is prevented is released, and the bill flipping denomination discrimination operation from the interruption point is automatically restarted. According to the invention, it is possible to easily confirm the abnormal bill at the time of interruption,
There is an effect that it is possible to automatically restart the bill flipping denomination determination operation from the point of time when the separation stop is interrupted.

In addition, the abnormal bill is suddenly stopped at the intermediate separating position, the abnormal bill that has been separated and separated is automatically returned to the uncounted bill side, and then the bill flipping determination operation is performed again. According to the invention, it is possible to perform the discrimination operation a plurality of times for abnormal bills, and to improve the discrimination system, and, for example, for a bill that has been double-adsorbed by mistake, return it to the uncounted bill side once. Thus, the probability that the sheets will be separated one by one at the time of another turning operation is increased, and the counting can be easily performed again. Therefore, the normal determination can be continuously performed easily.

Further, in the second invention in which the retry process is possible, when the same banknote is continuously discriminated as an abnormal banknote, the abnormal banknote is stopped at the separation stop position, and at this position, When the abnormal bill is confirmed, the suspended state that is prevented from being flipped is released, and the bill flipping determination operation from the point of interruption is automatically restarted. According to the third aspect of the invention, it is possible to easily confirm the abnormal bill at the time of interruption, and it is possible to automatically restart the bill flipping determination operation from the time point at which the separation stop is interrupted. .

Further, according to the first invention or the third invention in which the abnormal banknote stopped at the intermediate separating position can be easily confirmed, the fourth invention in which the denomination information can be further input For example, it is possible to accurately calculate the total amount of bills loaded in the holder based on the denomination information output during the turning operation of the suction shaft and the denomination information input at the time of interruption. It is effective.
