Description

[Detailed description of the invention]

"Industrial Application Field" The present invention relates to a banknote counting machine used in financial institutions such as banks, and in particular, a banknote counting machine that detects the presence or absence of abnormal banknotes by reading optical patterns on the surface of banknotes. The present invention relates to a discriminating device. "Prior art" Conventionally, as this type of banknote counting machine, the present applicant has developed a
A "discrimination device for a banknote counting machine" as shown in Japanese Patent No. 0-104979 has already been provided. This banknote counting machine uses vacuum pressure inside a suction shaft that rotates while revolving around the earth to attract and count banknotes loaded in a boulder one by one while flipping them over. It has a function to simultaneously check whether or not banknotes are mixed in. ``Problems to be Solved by the Invention'' By the way, in financial institutions such as banks where such banknote counting machines are used, it goes without saying that they check the number of banknotes, but they also check the number of banknotes, as well as check the number of banknotes. The number of banknotes (negotiable securities) is often checked, and a banknote counter that mainly counts and checks banknotes has been commonly used. However, when trying to count other paper sheets during banknote counting, people often forget to switch the discrimination mode to OFF mode due to their busy schedule, and in such cases, the first banknote is At the time of counting, it was determined that there was a discrimination error and counting was interrupted. Therefore, in this state, the clear operation was performed to open the holder, take out the paper sheets, set the mode again, load the paper sheets into the holder again, and start counting, which improved operability. It was getting crowded. The present invention has been made in view of the above circumstances, and is a bill counting machine that automatically cancels the detection mode and only performs counting when the first bill is judged abnormally during the detection mode. The purpose is to obtain a discrimination device for machines. "Means for Solving Problems" In order to achieve such an object, the present invention provides a bill counting machine that counts bills loaded in a holder by attracting them to a suction shaft and flipping them one by one. A different type of bill detection function that reads a surface pattern from the surface of the banknote and compares this surface pattern with pre-stored reference data to determine whether or not this banknote is a different type of banknote other than counted banknotes. A selection function for specifying the detection function to be ON or OFF; and a drive stop function for stopping the counting of banknotes when it is determined that the banknote is a discrimination abnormality that does not match the standard data by the face-printed different type of banknote detection function. In addition, this drive stop function is provided! An automatic cancellation function is provided that cancels the dissimilar bill detection function and starts counting when it is determined that the i-th banknote has a discrimination abnormality, and furthermore, the automatic cancellation function is turned on. A release alarm function is provided to output an abnormality detection signal when an error occurs. "Function" According to the present invention, an automatic canceling function is provided which cancels the dissimilar bill detection function and starts counting when the first bill is judged to have an abnormality. If the banknote in question is a paper sheet other than a banknote, only this paper sheet is counted. In addition, a release alarm function is provided that outputs an abnormality detection signal when the automatic release function is turned on, so that when the above-mentioned counting is completed, the operator, for example, can output an abnormality detection signal from the alarm function. By checking the abnormality detection signal, this count indicates that the different ticket detection function is OFF! It can be recognized that this was done in I3 (released state). "Example" The present invention will be described below based on an example shown in FIGS. 1 to 1O. First, the configuration of the banknote counting mechanism will be explained according to FIGS. 1 to 3. This counting mechanism places banknotes S on a holder l and horizontally rotates the holder l around an axis 2. Move it to the counting position shown by the solid line in Fig. 1 or the standby position shown by the chain line in Fig. 1, and when the holder l is in the counting position, rotate the rotary cylinder 3 counterclockwise in Fig. 1 about the shaft 4. At the same time, the suction shaft 5 on the rotary tube 3 is rotated clockwise around the shaft 6, and vacuum pressure is applied to the inside of the suction shaft 5 to turn over the banknotes S on the holder 1 one by one while counting. In addition, the basic configuration is such that the banknotes are identified by reading the reflected light of the light rays irradiated onto the surface of the banknotes S from a light projector, which will be described later, with a light receiver. The holder 1 is provided with a base plate 1a that supports the banknote S from the back side (opposite side of the suction shaft 5), and the surface tb of the base plate 1a is formed in a black color so as to reduce the level of reflected light. . The rotary cylinder 3 and the shaft 4.6 of the suction shaft 5 are formed in a hollow shape as shown in FIG. 3, and are connected to the suction boat 9 of the vacuum pump 8 via the suction pipe 7. The vacuum pressure of the vacuum pump 8 acts on the banknote S through an opening IO provided in a part of the outer circumference of the suction shaft 5, so that the banknote S is attracted to the suction shaft 5. . Further, a pressure sensor 11 is provided in the middle of the suction pipe 7, and this pressure sensor 11 allows the suction pipe 7 to
It is detected whether the vacuum pressure inside has risen to a level that can attract banknotes. On the other hand, an exhaust pipe line 13 is connected to the exhaust boat 12 of the vacuum pump 8, and this exhaust pipe line! 3 is provided with an exhaust nozzle 14 for blowing exhaust air onto the sides of the banknotes S to facilitate separation of the banknotes S. On the other hand, in the middle of the exhaust pipe line 13, a banknote nozzle 14 is provided for counting the banknotes. A solenoid valve 16 is provided to switch the exhaust to the discharge port 15 when the exhaust nozzle I4 is not in use, thereby preventing the generation of noise from the exhaust nozzle I4. Furthermore, a pair of position regulating pieces 5a are fixed to each of the suction shafts 5, as shown in FIGS. 1 to 3. The position regulating piece 5a protrudes from the side surface of the suction shaft 5 and is provided so as to sandwich the opening IO of the suction shaft 5 between the position regulating pieces 5a. Supports the banknote from the side when it is sucked,
This prevents the banknotes from falling or bending. In this way, the position regulating piece 5a allows the suction shaft 5 to maintain the upright state of the bills that have been sucked and separated, thereby detecting whether or not double feeding is being carried out (in FIG. 1, the bill is being sucked and separated). The banknote is positioned at position Sa). Further, a plurality of actuation pieces 17 made of magnetic material are attached to the outer circumference of the rotary cylinder 3, and each suction shaft 5 is moved to a standby position (opening) depending on whether or not these actuation pieces 17 actuate the magnetic sensor I8. Either the opening 10 is in the position directly facing the banknote and the inside of the suction shaft 5 is in communication with the vacuum pump 8), or the starting position (the position immediately before the opening 10 is facing the banknote,
In addition, it is detected whether the suction shaft 5 is inside the vacuum pump 8 (a device consisting of a vacuum pump 8). In addition, in FIG. 3, reference numeral 19 connects the rotary cylinder 3 to the belt 2.
A counting motor 21 drives the vacuum pump 8 via a belt 22, and a pump motor 21 drives the vacuum pump 8 via a belt 22.
3 is a holder motor that rotates the holder l, code 24
A and 24B are holder position detection switches that detect whether the holder I is in the closed position (close to the suction shaft 5) or in the open position (separated from the suction shaft 5). Further, a separator 25 is provided near the rotary cylinder 3, and this separator 25 is supported by a shaft 26 so as to be horizontally rotatable, and is biased counterclockwise in FIG. 1 by a spring 27. , is operated by a patch solenoid 28 to rotate it clockwise in FIG. As will be described later, this separator 25 has a function of being inserted between a banknote that has already been turned over and a banknote that has not yet been turned over and separating the two when a banknote of a different denomination is detected. There is. Next, a stamping mechanism for stamping a confirmation stamp on a bundle of banknotes will be explained with reference to FIG. 1. In FIG. 1, the reference numeral 30 indicates a seal holding member provided in the holder 1.
0, the seal stamp 31 is supported movably in the directions of arrows (a) and (b), and is movably supported so as to move toward and away from the bill S. Further, a dial 32 is provided at the base end of the holder 1, and by rotating this dial 32, the seal 31 can be moved by an arrow (
Move in the a) = (b) direction and press the stamping part 31a of the seal 31.
is aligned with Obifu B. Further, on the base supporting the boulder 1, there are provided a striking arm 34 that rotates in a horizontal plane about a shaft 33, and a solenoid 35 that rotates the striking arm 34. By rotating the solenoid 35 by the operation of the solenoid 35, the tip of the striking arm 34 presses the rear end 3tb of the seal from behind, bringing the stamping part 31a of the seal 31 close to the band, thereby sealing the band. A seal is placed on the top. Next, a mechanism for detecting double feeding of banknotes turned over by the suction shaft 5 will be described with reference to FIG. 1. In Fig. 1, the parts indicated by numerals 37 and 38 are a double feed detection lamp and a light receiving element (these elements constitute a double feed detection sensor), and the parts indicated by 3 are the light receiving element. A condensing lens that condenses light. Both the double feed detection lamp 37 and the light receiving element 38 are provided facing the rotary tube 3 side, and the light beam emitted from the double feed detection lamp 37 is directed toward the flipped bill Sa. The beam is irradiated from a direction crossing the banknote Sa, and is irradiated to approximately the center position of the peeled-off portion of the banknote Sa. The banknote Sa that has been irradiated with light in this way is
The amount of light that has passed through the banknote Sa, that is, the amount of transmitted light, is detected by the light receiving element 38, and further, based on the amount of transmitted light detected by the light receiving element 38, it is determined whether to double feed. In other words, if the amount of transmitted light is greater than a predetermined value, normal feeding (single sheet feeding) is determined, and if the amount of transmitted light is less than a predetermined value, it is determined to be double feeding. Next, a discrimination mechanism for discriminating the denomination and front and back of banknotes will be explained with reference to FIGS. 1 and 2. In the figure, the reference numeral 40 indicates a light projector that irradiates light onto the banknotes sb at the forefront of the stack, and the reference numeral 41 indicates a light receiver that receives the reflected light of the light irradiated onto the banknotes sb from the projector 40. (detection element), and the light beam emitted from the light projector 40 is adapted to be irradiated onto an area including area E indicated by the two-dot chain line on the banknote sb. The light receiver 41 also includes an area sensor 42 that generates an electric signal according to the pattern on the surface of the banknote, and a condenser lens 4 that focuses reflected light from the banknote sb onto the area sensor 42.
It is composed of 3. The area sensor 42 includes a plurality of linear image sensors arranged in a direction perpendicular to the line.
A dimensional sensor is operated by a trigger signal issued from a discrimination control circuit 46 (described later) to scan the area E, and convert the amount of reflected light at a specific position (line or coordinate) of this area E into an electrical signal. , which outputs a waveform signal that corresponds to the pattern on the banknote surface. In other words, the area sensor 42 has its horizontal direction corresponding to the X coordinate of area E, and its vertical direction corresponding to the Y coordinate of area E. Due to the correspondence with the XY coordinates, the surface pattern (line data) in area E can be read out by specifying the line, for example, Y=lSY=3, and furthermore, the read area data can be stored in the ROM 6.
4 (described later), it is possible to determine the denomination and front and back of the banknote sb (details will be described later). Next, as shown in FIG. 4, a counting control circuit (drive stop function) 45 and a discrimination control circuit (different type ticket detection function, drive stop function, automatic release function, release alarm function) 46 that operate the counting mechanism and discrimination mechanism, respectively, are operated. explain.

In addition to the clear switch, the operation switch 55 includes a changeover switch (automatic release function) for releasing the detection mode switch 53. This changeover switch can be set ON-OFF, and these ON-OFF settings are
This is done in conjunction with the N setting. That is, when the detection mode switch 53 is set to ON and the changeover switch is set to OFF, the first bill in the bundle of banknotes to be counted and determined is determined to be an abnormal banknote by the determination mechanism. When it is determined that this is the case, counting and discrimination of banknotes is not started. Similarly, when the detection mode switch 53 is set to ON and the notation changeover switch is set to ON, the discrimination mechanism determines whether one of the bill bundles to be counted or discriminated is
When it is determined that the first banknote is an abnormal banknote, the detection mode switch 53 is automatically turned off, and the banknotes are not discriminated but only counted. In addition, in this way, the detection mode switch 53 is automatically set to O.
When the switch is switched to FF and only banknotes are counted, a display (for example, a buzzer) indicating that the detection mode switch 53 has been automatically canceled is displayed on the display section (cancellation alarm function).

The output of the area sensor 34 is sent to the amplifier 72, the A/D converter 73, the input terminal [10] and the CP via the port 74.
It is designed to be input to U66. Note that the drive signal supplied from the drive circuit 71 to the area sensor 34 is X! lI] It consists of a drive signal and a Y-axis drive signal, and the surface pattern (area data) at a specific position in area E of the banknote is read out by outputting these X-axis drive signals and Y-axis drive signals. There is. When extracting surface pattern data in area E, first output a Y-axis drive signal to determine the Y coordinate of area E (see Figure 2).

The contents of the program stored in the ROM 47 of No. 5 will be explained together with the operation of the banknote counting machine. Note that SN in FIG. 5 indicates step N in the following explanation, and Tn in FIG. 9 indicates timing Tn in the following explanation. (a) ◇ Counting control operation 1 (see Figures 5 and 9) <Step l> Power on <Step 2> Based on the output signals of the holder position detection sensors 24A and 24B, check whether the boulder l is in the open position or not. If the answer is NO, the holder motor 23 is driven to set the boulder 1 to the open position (step 3), and if the answer is YES, the process proceeds to the next step 4). Step 4> Based on the output from the rotating cylinder position sensor 18, it is determined whether the suction shaft 5 is in the standby position (that is, the position where the suction shaft 5 directly faces the banknote). , counting motor! 9 is driven at low speed to set the suction shaft 5 to the standby position (step 5). If YES, the process proceeds to the next step 6. <Step 6> Determine whether or not the mode setting operation has been performed, and press YES.
In the case of S, the stamping mode is memorized by various mode setting operations, for example, stamping mode operation settings, step 50.
), and in the case of No, proceed to the next step 7. <Step 7> It is determined whether the start signal (ST) has been output from the start switch 52, and if No, the step 6 is performed.
If the answer is YES, the process proceeds to the next step 8 (timing T). Step 8) Determine whether the detection mode switch 53 is ON or not. If YES, turn on the double feed detection lamp 37 and floodlight 40 (Step 9); if NO, proceed as follows. Proceed to step 10 to start counting operation. Step 10> Based on the outputs of the holder position sensors 24A and 24B, it is determined whether or not the holder 1 is in the closed position. If NO, a holder motor drive signal (t-rMD) is output, and the holder motor drive signal (t-rMD) is output. The motor 23 is driven to set the holder 1 to the closed position (step 11), and if YES, the process proceeds to the next step 12 (timing 'rt). Step 12> A pump drive signal (PMP) is output to drive the pump motor 21, and a solenoid valve drive signal (SV) is output to switch the solenoid valve I6 to the exhaust nozzle I4 side. <Step 13> It is determined whether or not the suction shaft 5 is at the starting position. If NO, a counting motor drive signal (CMD) is output and the counting motor! 9 in the opposite direction at low speed to set the suction shaft 5 to the starting position (step 14), and if YES, proceed to the next step (timing T3). <Step 15> Determine whether or not the pressure determination signal (VSW) is output,
That is, it is determined whether the vacuum pressure in the suction pipe line 7 has increased to a predetermined value, and if the answer is No, a predetermined time (the time required for the vacuum pressure to rise) has elapsed from the timing T3. If step 16 is No, the process returns to step 15, and if step 16 is YES, the suction failure processing rule (described below as a chain line A in FIG. 5) is determined. (shown). On the other hand, if this step 15 is YES, the process proceeds to the next step 17 (timing T). <Step 17> When the pressure nozzle J III separate signal (VSW) is output (step 15), the counting motor drive signal (CM D
) is output, and the rotating cylinder 3 and suction shaft 5 start rotating. Step 18 > The suction shaft 5 counts the bills while flipping them one by one, and every time the rotary barrel position sensor [8 generates a signal (SNS), a trigger signal (T RG) is output. Also, at this time, a counting signal (CN'r) is output, and the banknotes are counted (or discriminated) (timing T e - Tm).
. <Step 19> Determine whether or not the pressure determination signal (VSW) is output, that is, whether or not there are no bills to be turned over and the vacuum pressure in the suction pipe 7 cannot be increased (OFF). Then, on the condition that it is turned OFF (timing Tm++), the process proceeds to the next step 20. Step 20> Stop the counting motor 19 and pump motor 21. Step 2 [>] In parallel with the stopping operation of the rotary cylinder 3 in step 20,
It is determined whether or not the oven signal of the holder has failed to be output, and if YES, the process returns to step 2 (timing Tn
), in the case of rvo, it waits in step 21. Then, when returning to step 2 (timing T
n), it is determined whether holder 1 is open or not, and the holder motor drive signal (
I(M D ) is output. Then, the boulder opens (step 4; timing Tn+
+), the motor drive signal (HMD) turns OFF and at the same time the counting motor drive signal (CMI:)) is output to drive the counting motor 19. When the suction shaft 5 is moved to the standby position by the drive of the counting motor 19, the output of the rotary cylinder position sensor 18 is turned on, and at the same time, the counting motor 19 is stopped.
timing 'I'n+2). When the suction shaft 5 is stopped at the standby position in this way, the next start signal (step 7) makes it possible to immediately start counting, and the next bet is completed. Next, the suction and defect processing route A will be explained. In other words, if the rotary cylinder 3 cannot be stopped at a predetermined position due to a malfunction of the brake of the counting motor 19, etc., the suction pipe 7 will not be sealed from the inside or outside, and the suction pipe 7 will not be sealed from the inside or outside, so that the rotary cylinder 3 will not be able to stop after a certain period of time has elapsed. Even if the vacuum pressure is not increased, the pressure judgment signal cannot be turned ON (
Step 16). In such a case, the counting motor 19 is rotated in reverse at a constant speed to adjust the position of the rotary cylinder 3 (step 30), and steps I3 to 15 are repeated. If the vacuum pressure does not increase even after repeating this operation N times (step 31)
To stop the pump motor 21 (step 32),
An alarm signal is output (step 33), and the machine is then stopped (step 34). Next, we will discuss the counting process flow in the CPU 49 in the sixth section.

The data is supplied to the determination routine shown in the figure (indicated by the arrow ■). Furthermore, if the detection mode switch 53 is OFF, it is determined that only counting is to be performed, and the next step 1 is performed.
Proceed to 03. <Step 103> Detect the rise of the rotary cylinder position sensor output signal (SNS), and if YES, proceed to the next step 104. <Step 104> When the trigger signal (TRG) is raised at the same timing as step 103, the output of this trigger signal (TRG) is supplied to the discrimination routine shown in FIG. show). <Step I05> Detect the ON-OFF state of the rotary cylinder position sensor output signal (SNS), and if ON (YES), determine whether the pressure judgment signal (VSW) is ON or not.Step 106 ), if this step 106 is No, output the discrimination OFF signal (step 150 ), and stop driving the counting motor 19 and pump motor 21 and turning on the double feed detection lamp 37 and the floodlight 40 ( Step 15I). Further, in the step 106, if the pressure determination signal (VSW) is output (YES), the process proceeds to the next step 107. <Step 107> It is determined whether or not the detection mode switch 53 is turned on. If YES, proceed to step 108; if NO, proceed to step 109. <Step 108> If a different denomination is detected, if a discrepancy between the front and back sides is detected in the front/back discrimination mode, if the pattern does not match all the reference patterns and is judged to be a discrimination abnormality, or if double adsorption is detected. In this case, it is determined whether there is human power to generate the error signal (indicated by the arrow ■) output from the discrimination processing flow, and the answer is YES.
In the case of NO, the batch solenoid 28 is operated to interrupt counting, and in the case of NO, the process proceeds to step 109. <Step 109> Determine whether batch mode is ON or not, and select NO.
If YES, the process returns to step 105, and if YES, the process proceeds to step 110. <Step +10> The number of banknotes is determined, and if it is determined that the banknote count is less than the predetermined number (No), the process returns to step 105, and if the banknote count has reached the predetermined number. If it is determined (YES), turn on the patch solenoid 28.
After separating the counted banknotes from the uncounted banknotes (at step +tB, a discrimination OFF signal is output (step 11).

Then, the process proceeds to the next step 114. Step 114> In step 218, it is determined whether or not a flag indicating automatic release of the detection mode switch 53 is set in the RAM 65. If YES, a buzzer is activated on the display 63. After indicating to the operator that the detection mode has been canceled by

Further, if the determination in step +14 is NO, that is, if the automatic release setting (set in step 218) has not been made, the process proceeds to the next step 116. <Step 116> It is determined whether a clear operation has been performed to cancel the operation of the separator 25 that was activated during the batch processing or when an error was detected, and if YES, the process proceeds to step 117. <Step 117> An oven signal (see step 2I) is output to holder l, and this flow ends. Next, steps 120 and 121 will be explained. Step 120> In step 105, the ON-OFF state of the rotary cylinder position sensor output signal (SNS) is detected and turned ON.
If the state is, steps 105 to 109 are performed.

When the F state is reached, the process moves to step 120. Then, as in step 106, it is determined whether the pressure determination signal (VSW) is ON, and if the determination is No, the process proceeds to the next step l50, as in step 106. , outputs a discrimination OFF signal (step 150), and stops the driving of the counting motor 19 and pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 (step 151). Further, if w of the pressure determination signal (VSW) is YES, the process proceeds to step +21.

Step 150> As described above, in steps 106 and 120, if the output of the pressure determination signal (VSW) is not detected, for example, if the banknotes in the standby position are not picked up, or if there are no banknotes to be counted, etc. , the determination OF signal is output, and after the driving of the counting motor 19 and the pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 are stopped (step 15), the process proceeds to step 52. Step 152 In step 2+8 of the determination routine (described later), the TI
It is determined whether or not a flag indicating automatic release of the detection mode switch 53 is set on the AM65, and if YES, after indicating to the operator that the detection mode has been released using a buzzer or the like on the display unit 63 ( Step +15), proceed to step 116. Further, if the determination is NO in step 152, that is, if the automatic release setting (set in step 2+8) has not been made, the process proceeds to the next step 153. Step 153> It is determined whether or not the detection mode switch 53 is turned on. If NO, the process proceeds to step 160; if YES, the process proceeds to step 154. <Step 154> If the end signal (indicated by the arrow ■) is not output from the discrimination routine for a certain period of time (step +55), for example, even though banknotes to be counted are set, If the banknote is not adsorbed, a flag indicating a residual error is set in a predetermined area of the storage unit (RAM 48 or CPU 49) (step 156).
), proceed to the next step 116. Further, if an end signal is output from the determination processing flow shown in FIG. 7, the process proceeds to the next step 160. Step 160> Determine whether the mode setting is the number of sheets check mode, and if NO, proceed to step +64 and select YES.
In this case, the process advances to step 161. <Step 161> Determine whether the counted value of banknotes matches the number set in the number check mode, and select No.
In this case, a flag indicating a mismatch error is set in a predetermined area of the storage section (step 166), and the process proceeds to step 116. Further, if the set number of sheets and the count value match (YES), the process proceeds to the next step 162. <Step 162> Determine whether or not the mode setting is set to stamping mode. If YES, operate the stamping solenoid 35 to stamp the seal (Step 163); if NO, perform the following steps. Proceed to step 164. Step 164> Determine whether the addition mode is set and select YES.
In the case of , add the counting results of the banknotes counted earlier,
The addition result is stored in the storage section, and in the case of No, the process proceeds to step 117 and the counting process ends. Next, the seventh section regarding the determination processing flow in the CPU 66 will be explained.
This will be explained with reference to the time charts shown in FIG. 8, FIG. 8, and FIG. 1O. Step 200> Start <Step 20I> Determine whether or not a trigger signal ('1'' IIG) (indicated by an arrow ■) is output from the counting routine, and if YlεS, proceed to the next step 202. Step 202 〉 It is determined whether the determination ON signal (indicated by the arrow ■) is output from the counting routine, and if No, step 201 is performed.
If the answer is YES, select the analog switch 80 shown in FIG. After memorizing (step 203)
, proceed to step 204. Step 204> Based on the error codes set in Steps 214, 226, and 232, it is necessary to judge whether there is a mixture of different denominations, a discrepancy between the front and back sides, and whether there is a discrimination error (contamination of abnormal banknotes). Contamination of denominations, mismatch between front and back sides,
For detection of discrimination abnormality, step 213.225.2
31), if YYεS, an error signal and error code are output, and the error details are displayed on the display unit 6.
3 (step 205), the process returns to step 201. Incidentally, the error signal outputted in step 205 is supplied to step 108 of the counting routine in FIG. 6, as indicated by the arrow ■. If there is no mix-up of different denominations, no discrepancy between the front and back sides, or a discrimination error (No), the process proceeds to the next step 206. Note that when the first trigger signal (T rt G ) is output, the step 214, 226, 232 has not been passed and no determination has been made, so the first step 2.4 is always NO and the process proceeds to step 206. Step 206> Based on the detection data taken in from the double feed detection sensors 37 and 38 in step 203 and the double comparison level serving as the discrimination standard set in step 221 (described later), it is determined whether the bill is double adsorbed. If it is YES, it outputs an error signal and an error code, and displays the error details on the display unit 63 (step 207).
, return to step 201. Note that the error signal output in step 207 is sent to step 10 of the counting routine in FIG. 6, as indicated by the arrow ■.
8. Further, in the case of No, that is, when it is determined that there is no double adsorption, the process proceeds to the next step 208. Note that, similarly to step 204, the first trigger signal (T
RG) At the time of output, the banknote Sa that should be judged as double suction
does not exist in the position shown in Figure 1, and the base double comparison level has not been set, so this step 206
is always No and proceeds to step 208. <Step 208> By selecting the analog switch 79 shown in FIG. 4 and storing the output of the area sensor 34 in the RAM 65 via the amplifier 72 and A/D converter 73, area data in area E (data in ) will be imported. Note that this area data is taken in based on the flow shown in FIG. In other words, when the capture signal is output (step 30
0), Y is set to 0, and X is set to 0 (step 301
), proceed to the next step 302. In this step 302, it is determined whether or not the output of the necessary N lines of data (line data) has been completed, and if YES, a determination start signal is output (step 303), and the seventh Return to Iin Luzhin in the figure. Further, in the case of No in step 302, steps 304 to 3 are continued until the data of the designated N line is output in step 312.
11 is looped, and when the data is output, the process proceeds to step 303 as described above. When the line-by-line capture of area data is completed in this way, the process proceeds to the next step 209 shown in FIG. Step 209> Whether or not the data imported in step 208 is at a level that does not have a pattern (i.e., if the data is at a level that does not have a pattern
YlεS
If (no data), the process returns to step 201 after outputting a second signal (step 2IO). In addition,
The end signal output in step 210 is supplied to step 153 of the counting routine in FIG. 6, as indicated by arrow . In addition, if the imported area data is of a level with a pattern (NO), the next step 2+1
Proceed to. <Step 211> It is determined whether or not the bill attracted by the suction shaft 5 is the first one. If YES, proceed to step 2!2; if NO, proceed to step 230. Step 212> A total of 12 patterns (4× patterns) of the current 3 denominations (L denominations) stored in the ROM 64 are applied to the Eriazo-yen of the first banknote imported in step 208. (for l denomination, there are four patterns of front and back, forward and reverse), and the process proceeds to the next step 213. Step 213> As a result of comparing the area data of the first banknote with the reference data of the 12 patterns, it is determined whether there is a matching pattern, and if YES, the process proceeds to step 219, and if No. If so, proceed to step 2+4. Step 2I4> Determine whether the changeover switch (operation switch 55) is set to OFF, and if YES, proceed to step 2I4.
The process proceeds to step 15, where the first banknote is determined to be an abnormal banknote that cannot be determined, and a flag indicating the determination abnormality is set in a predetermined area of the storage unit (RAM 65) (step 215), and the process returns to step 201. Further, if NO in step 214, that is, if the changeover switch is set to ON, first, after releasing the detection mode switch 53 (step 2
16), to output a discrimination OFF signal to stop reading the surface pattern of the banknote (step 217), and then to a predetermined area of the storage unit (RAM 65) to indicate that the detection mode switch 53 has been released (set to OFF). A flag indicating this is set (step 218). Note that the determination OF output in step 217
The F signal is provided to step 202 and the stored data stored in step 218 is provided to steps 114 and 152 of the counting routine described above. Step 219> On the other hand, in step 213, the area data and 1
There is a pattern that matches the standard data of two patterns (
In the case of YES), the banknote identified in the predetermined area of the storage unit (RAM65) is one of the three denominations.
After setting a flag indicating that the banknote is a banknote and further setting a flag indicating the front and back sides of the banknote (step 220), double adsorption is determined based on the determined denomination and front and back information, which is stored in the ROM 64. The standard double comparison level is stored in the storage section (
RAM 65) (step 221), the process advances to step 222. Step 230> On the other hand, in step 211 described above, the suction shaft 5
If it is determined that the sucked bill is not the first bill, the area data of the bill imported in step 208 and the specific denomination stored in the ROM 64 (the denomination set in step 219) Compare only the standard data of 4 patterns of front, back, forward and reverse for
Proceed to +. Step 231> As a result of comparing the area data of the banknote with the four patterns of reference data, it is determined whether there is a matching pattern, and if NO, this banknote is a banknote of a different denomination (strictly speaking, A flag indicating a different denomination is set in a predetermined area of the storage unit (step 232).
), the process returns to step 201. Further, if there is a matching pattern (YES), as described above, a flag indicating the front and back of the banknote is set in a predetermined area of the storage unit (step 220), and further, in step 221, the storage unit is Set the double comparison level, which is a discrimination criterion, in a predetermined area, and proceed to the next step 22.
Proceed to step 2. <Step 222> It is determined whether the front/back mode switch 54 is turned on. If NO, proceed to step 201; if YES, proceed to the next step 223. Step 223> Determine whether or not this bill is the first bill, and press N. If YES, proceed to step 225; if YES, proceed to the next step 22.4. <Steps 2 to 4> The front and back codes of the first banknote set in the 1-recordable step 220 are used as the front and back reference data in the storage unit n A M
65, and based on this front/back reference data, the front/back side of the banknote is determined (step 225). Step 225> Front and back codes set in step 220 and step 2
The front and back reference data set in step 24 are compared to determine whether the second and subsequent banknotes match the front and back of the first banknote, and if they match (YES), Returning to step 201, if there is a mismatch (No), proceeding to the next step 226. In this step 226, a flag indicating that the front and back sides do not match is set in a predetermined area of the storage unit (step 226), and the process proceeds to step 201. Go back, again” double steps 201 to 232
repeat. Note that the above-mentioned trigger signal (T RG ), timing for capturing double data, etc. are described in the timing chart of FIG. 10. These trigger signals (
TrtG), the timing of capturing double data, etc. corresponds to the step numbers in FIG. corresponds to step 204, double check timing corresponds to step 206, area data import timing corresponds to step 208, end check timing corresponds to step 209, and determination processing timing corresponds to steps 211 to 213 and step 209. 230.
231, and also includes denomination, front and back, double comparison level,
Error set timing is steps 219 to 2211
They correspond to steps 214, 226, and 232, respectively. In the case of a discriminating device in a banknote counting machine configured like a two-legged machine, when the detection mode switch 53 is set to ON, the changeover switch (operation switch 55) having an automatic release function is set to ON at the same time. , when the first bill is an abnormal bill that cannot be distinguished (step 213), the writing detection mode switch 53 is automatically released (OF
F) (step 216), the discrimination of different types of banknotes is interrupted at the first banknote, and only these banknotes are counted (steps +14, 152, 21).
7). Then, when the detection mode switch 53 is automatically released and only the banknotes are counted, the display section 63 issues an alarm such as a buzzer indicating that the detection mode has been released (step 115). ), the operator etc. can recognize that only counting is being performed. As a result, in the above discriminating device, for example, 1
Even if the first banknote is determined to be an abnormal banknote, at least counting will be performed, and the operator will be able to recognize the counting done in this way, so the counting will be completed. At this point, after the operator inspects the first banknote, the discrimination and counting operation can be started again. Further, although the detection mode switch 53 is released by setting the changeover switch to ON, the present invention is not limited to this, and when the detection mode switch 53 is turned ON, the changeover switch is automatically turned ON. You can do it like this. Furthermore, when changing the program for discriminating Japanese banknotes to a program for discriminating US dollar bills, this is done by replacing the ROM 64 and the like. In addition, the above-mentioned discrimination control circuit 46 inputs the line data to
Although it is taken out along the axis, the invention is not limited to this, and it may be taken out along the Y axis. Furthermore, as a sensor for reading the surface pattern in the area E, in place of the surface area sensor 34, a plurality of one-dimensional image sensors are arranged at intervals with respect to the Y axis or the X axis shown in FIG. The detected data may be read out by specifying a column. Furthermore, in this banknote counting machine, the arrangement of the stamping mechanism that stamps the seal and the double feed detection mechanism that detects double feed is careless. "Effects of the Invention" As explained in detail above, according to the present invention, when the first bill is judged to have an abnormality, the dissimilar bill detection function is canceled and counting is started automatically. Since this function is provided, if an attempt is made to count paper sheets other than banknotes, or if the first banknote is a banknote with an abnormality, discrimination is stopped and only banknotes are counted. It will be done. In addition, there is a release alarm function that outputs an abnormality detection signal when the automatic release function is turned on, so when the above-mentioned counting is completed, for example, the operation sound is
By checking the abnormality detection signal output from the alarm function described in q, it is possible to recognize that this counting was performed with the dissimilar ticket detection function in the OFF state (cancelled state). This makes it possible to prevent the risk of confusing paper sheets that are classified with paper confections that are not classified, and to handle paper sheets other than banknotes without worrying about the mode.
Good operability is achieved by being able to count without any trouble.
