Next, in the banknote transaction apparatus having the above configuration,
An example of a device down prevention measure at the time of a sensor failure will be described. In each embodiment, the schematic configuration of the apparatus and the control unit is as shown in FIGS. FIG. 4 shows the flow of a process at the time of a jam check, which is common to some of the first to third embodiments and the fourth embodiment. (First Embodiment) FIG. 3A shows a layout of a conveyance path and sensors according to the present embodiment, and FIG. 3B shows sensor output timing. This embodiment is an embodiment of the first and second aspects of the present invention. The bill moves from the left side to the right side in FIG. The distance a between the sensor 34 and the sensor 35 is 10
0 mm. The distance b between the sensor 35 and the sensor 17 is 2
50 mm. The transport path is provided with an encoder (not shown) for detecting the number of transports, and the transport number is incremented by one every time the transport path moves by 1 mm. Next, according to FIG.
Outputs 5 and 17 will be described. The horizontal axis indicates the number of conveyance. Also, the output of each sensor is 1 and dark (the bill is on the transport path) and “0” and light (the bill is not on the transport).
The state is shown. First, the case where the slip between the bill and the transport path is “0” will be described. For the number of transports "0",
Since the leading end of the bill is transported to the sensor 34, the output of the sensor 34 changes from "0" to "1". Furthermore, for example, 76m
When the object m moves, the output of the sensor 34 changes from “1” to “0”. FIG. 3B shows the following sensor output change timings of the sensors 17 and 35 and a change in the number of conveyances detected by the encoder.

Next, a jam check method according to this embodiment will be described with reference to FIG. The encoder monitoring process updates the number of transports each time an encoder change is detected (N in step 401, Y in 402) (step 40).
3). When the change timing is detected for all sensors on the transport path (N in step 411, Y in 412), the sensor monitoring process stores the number of transports at that time (step 413). The destination of the bill detected by the sensor is
Since it is determined when the bill passes through the discrimination unit 6, the number information of the pass sensor that passes after the bill is also stored (step 41).
3). The sensor change timing check process checks whether the passage timing of the conveyed object at the passage point is appropriate for all the sensor sections (N, 4 in step 421).
22). For example, if the passing timing of the sensor 35 is too early for the number of conveyed articles that have passed the sensor 34 (Y in step 423), a springing abnormality occurs (step 424). If it is too late (N in step 423), a section jam occurs (step 425). In the bill length check processing, the number of continuously conveyed dark numbers on the sensors is checked for all the sensors. For example, when conveying a banknote of 76 mm, consider the margin,
If the length is between 60 mm and 85 mm, it is determined to be normal (N in step 431, Y in 432), and if it is less than that, the short banknote is abnormal (N in step 432, Y in 433, 43
4) If it is longer than that, it is determined that the long bill is abnormal (N in step 432, N in 433, 435).

Next, a method for producing a dummy sensor output in this embodiment will be described with reference to FIG. The output of the normal sensor 34 is, as described above, the transport number “0” to “76”.
Between is dark. Using this information, the sensor 35
Is shifted by 100 pulses by the distance from the sensor 34 to the sensor 35, information on the dummy sensor can be obtained. Next, the fact that the sensor does not go down even if the sensor fails will be described. At the start of ATM transaction, light check and dark check of all sensors are performed. When it is determined that the sensor 35 is defective, the output of the sensor 35 is stopped and the dummy output is used. Therefore, the sensor 35 becomes ideal sensor output information, and springs out, section jam, long bill abnormality, short bill abnormality. And all checks can be reduced. Note that such degeneration processing is performed by the main control unit (48 in FIG. 2) and the sensor control unit (FIG. 2).
39).

(Second Embodiment) FIG. 5A shows a layout of a conveyance path and sensors according to this embodiment, and FIG. 5B shows sensor output timing. This embodiment is an embodiment of the third aspect of the present invention. The bill moves from the left side to the right side in FIG. Distance a between sensor 31 and sensor 34
Is 100 mm. The distance b between the sensor 34 and the sensor 35 is 250 mm. The transport path is provided with an encoder (not shown) for detecting the number of transports, and the transport number is incremented by one every time the transport path moves by 1 mm. Next, according to FIG.
The output of 1, 32, 34, 35 will be described. The horizontal axis indicates the number of conveyance. Further, the output of each sensor is 1 to indicate a dark state (the bill is on the transport path), and “0” to indicate a light state (the bill is not on the transport). First, the case where the slip between the bill and the transport path is “0” will be described. In the case of the transport number “0”, since the leading end of the bill is transported to the sensor 31,
The output of the sensor 31 changes from “0” to “1”. Further, when a conveyed object of, for example, 76 mm moves, the output of the sensor 31 changes from “1” to “0”. The following sensor output change timing is as shown in FIG. Also, when the banknote reaches the position of the gate after passing the sensor 31, the destination of the banknote has already been determined by the discriminating unit 6 to go in the direction of the sensor 34. The state shown in FIG.
Flows in the direction.

Next, a jam check method in this embodiment will be described with reference to FIG. The encoder monitoring process updates the number of transports each time an encoder change is detected (N in step 401, Y in 402) (step 40).
3). When the change timing is detected for all sensors on the transport path (N in step 411, Y in 412), the sensor monitoring process stores the number of transports at that time (step 413). The destination of the bill detected by the sensor is
Since it is determined when the bill passes through the discrimination unit 6, the number information of the pass sensor that passes after the bill is also stored (step 41).
3). The sensor change timing check process checks whether the passage timing of the conveyed object at the passage point is appropriate for all the sensor sections (N, 4 in step 421).
22). For example, when the banknotes are flowing in the direction of the sensor 34 at the gate 12, the passage timing of the sensor 34 is too early in relation to the number of conveyed articles passing the sensor 31 (N in step 422, Y in 423). ) And when the banknote passes through the sensor 32, a springing-out error occurs (step 424). If it is too late (Step 4
22 (N of 423, N of 423), and a section jam occurs (step 425). If the gate 12 causes banknotes to flow in the direction of the sensor 32, the passage timing of the sensor 32 is too early for the number of conveyed articles that have passed the sensor 31 (N in step 422, Y in 423). ), And when the banknote passes through the sensor 34, a springing out occurs (step 424). If it is too late (N in step 422, N in 423), a section jam occurs (step 42).
5). In the bill length check processing, the number of continuously conveyed dark numbers on the sensors is checked for all the sensors. For example, when a banknote of 76 mm is conveyed, the case of 60 mm to 85 mm is determined to be normal in consideration of the margin (N in step 431, Y in 432), and if it is smaller than that, the short banknote is abnormal (N in step 432). , 43
(3, Y, 434), and if it is longer than that, it is determined that a long bill is abnormal (N in step 432, N, 435 in 433).

Next, a method of producing a dummy sensor output in this embodiment will be described with reference to FIG. The output of the normal sensor 31 is, as described above, the transport number “0” to “76”.
Between is dark. Utilizing this information, first, the next pass sensor through which the bill passing the sensor 31 passes is the sensor 3
In 4, when the banknote is in the direction of the sensor 34 at the gate 12, the information of the dummy sensor can be obtained by shifting the output of the sensor 34 by 100 pulses from the sensor 31 by the distance of the sensor 34. Next, in the opposite case in FIG. 5, the next passage sensor through which the bill passing through the sensor 31 passes is the sensor 32, and the gate 12 does not change the output of the sensor 34 when the bill is in the sensor 32 direction. Thus, information of the dummy sensor can be obtained. In addition,
Regarding that the sensor does not go down even if it fails,
For the same reason as in the embodiment.

(Third Embodiment) FIG. 6A shows a layout of a conveyance path and sensors in this embodiment, and FIG. 6B shows a sensor output timing. This embodiment is an embodiment of the invention described in claim 4. The bill moves from the left side to the right side in FIG. The distance a between the sensor 18 and the sensor 19 is 100 mm. The distance b between the sensor 19 and the sensor 21 is 250 mm. The distance C between the sensor 20 and the sensor 19 is 150 mm. The transport path is provided with an encoder (not shown) for detecting the number of transports, and the transport number is incremented by one every time the transport path moves by 1 mm. Next, the outputs of the sensors 18, 19, 20, 21 will be described with reference to FIG. The horizontal axis indicates the number of conveyance. Further, the output of each sensor is 1 to indicate a dark state (the bill is on the transport path), and “0” to indicate a light state (the bill is not on the transport). First, the case where the slip between the bill and the transport path is “0” will be described. When the number of transports is “0”, since the leading end of the bill is transported to the sensor 18, the output of the sensor 18 changes from “0” to “1”.
Further, when a conveyed object of, for example, 76 mm moves, the sensor 18
Changes from “1” to “0”. The following sensor 1
The change timings of the sensor outputs 9, 20, and 21 and the change in the number of conveyances detected by the encoder are shown in FIG.
This is as shown in FIG.

Next, a jam check method according to this embodiment will be described with reference to FIG. The encoder monitoring process updates the number of transports each time an encoder change is detected (N in step 401, Y in 402) (step 40).
3). When the change timing is detected for all sensors on the transport path (N in step 411, Y in 412), the sensor monitoring process stores the number of transports at that time (step 413). The destination of the bill detected by the sensor is
Since it is determined when the bill passes through the discrimination unit 6, the number information of the pass sensor that passes after the bill is also stored (step 41).
3). The sensor change timing check process checks whether the passage timing of the conveyed object at the passage point is appropriate for all the sensor sections (N, 4 in step 421).
22). For example, if the passing timing of the sensor 19 is too early for the number of conveyed articles that have passed the sensor 18 (N in Step 422, Y in 423), a springing abnormality occurs (Step 424). If it is too late (N in step 422, N in 423), a section jam occurs (step 425). The same applies to the sensor change timing check processing for the conveyed object that has passed the sensor 20. In the bill length check processing, the number of continuously conveyed dark numbers on the sensors is checked for all the sensors. For example, when a banknote of 76 mm is conveyed, the case of 60 mm to 85 mm is determined to be normal in consideration of the margin (N in step 431, Y in 432). , 433
Y, 434), and if it is longer than this, it is determined that the long bill is abnormal (N in step 432, N, 433 in 433).
5).

Next, a method of producing a dummy sensor output in this embodiment will be described with reference to FIG. When the bill passes the sensor 18, the output of the normal sensor 18 becomes dark between the transported numbers 0 to 76 as described above. Using this information, the information of the dummy sensor can be obtained by shifting the output of the sensor 19 by 100 pulses from the sensor 18 by the distance of the sensor 19. Also, in the opposite case in FIG. 6, when the bill passes through the sensor 20, the output of the normal sensor 20 is dark between the transported numbers "0" and "76". Using this information, the information of the dummy sensor can be obtained by shifting the output of the sensor 19 by 150 pulses from the sensor 20 by the distance of the sensor 19. Note that the fact that the sensor does not go down even if the sensor breaks down is for the same reason as in the first embodiment.

(Fourth Embodiment) FIG. 7A shows a layout of a conveyance path and sensors in this embodiment, and FIG. 7B shows a sensor output timing. This embodiment is similar to the fifth embodiment.
It is an example of the described invention. The bill moves from the left side to the right side in FIG. The distance a between the sensor 34 and the sensor 35 is 100 mm. The distance b between the sensor 35 and the sensor 17 is 250 mm. The sensor 34 is on the transport path (1)
Above, the sensors 35 and 17 are on the transport path (2). The distance x from the sensor 34 to the transport path (2) is x = 80 mm, and the distance y therefrom to the sensor 35 is y = 20 mm. Each of the transport paths (1) and (2) is provided with an encoder (1) and (2) (not shown) for detecting the number of transports. It is assumed that the number is incremented by one. The speed of each of the transport paths is 200 m / s for the transport path (1) and 400 m / s for the transport path (2).
The transport path (2) is twice as fast as the transport path (1).
When a banknote straddles the transport path (1) and the transport path (2), it is transported at the speed of the transport path (2). Next, the outputs of the sensors 34, 35 and 17 will be described with reference to FIG.
The horizontal axis indicates the number of conveyance. The output of each sensor is "1" indicating dark (the bill is on the transport path) and "0" indicating a light (no bill is on the transport) state. First,
The case where the slip between the bill and the transport path is “0” will be described. At the transport number “0” in the transport path (1) and the transport path (2), the leading end of the bill is transported to the sensor 34,
The output of the sensor 34 changes from “0” to “1”. Further, for example, when a 76 mm conveyed object moves on the conveying path (1), the output of the sensor 34 changes from “1” to “0”.
The following sensor output change timings of the sensors 17 and 35,
FIG. 7B shows the change in the number of conveyances detected by the encoders of the conveyance paths (1) and (2).

Next, a jam checking method according to the present embodiment will be described with reference to FIGS. Here, the encoder monitoring process uses the encoder monitoring process of FIG. 8 because the transport speed differs depending on the transport path. That is, the encoder monitoring process is performed in each of the transport paths (1) and (2) by using the encoder (1) or (2).
(Steps 801 to 803, 80
5) Update the number of conveyances on each conveyance path (Step 80)
4,806). A in step 805 corresponds to FIG.
Means the transport number “A” of the transport path (1). In the sensor monitoring process, when the change timing is detected for all the sensors on the transport path (N in step 411 in FIG. 4, Y in 412), the number of transports in each transport path at that time is stored (step 413). Further, since the destination of the bill detected by the sensor is determined when passing through the discriminating unit 6, the number information of the passage sensor that passes next to the bill is also stored (step 4).
13). The sensor change timing check process checks whether or not the passage timing of the conveyed object at the passage point is appropriate for all the sensor sections (N in step 421).
422). For example, when the passing timing is too early (N in step 422, Y in 423) if the number of conveyances on the conveyance path 2 of the sensor 35 is too early compared to the number of conveyances on the conveyance path (2) of the conveyed object that has passed the sensor 34 A springing abnormality occurs (step 424). If it is too late (N in step 422, N in 423), a section jam occurs (step 425). In the bill length check processing, the number of continuously conveyed dark numbers on the sensors is checked for all the sensors. For example, when a bill of 76 mm is conveyed, the case of 60 mm to 85 mm is determined to be normal in consideration of the margin (N in step 431, Y in 432), and
If it is less than this, the short bill is abnormal (N in step 432, Y, 434 in 433), and if it is more than that, it is determined that the long bill is abnormal (N in step 432, N, 435 in 433).

Next, a method of producing a dummy sensor output will be described with reference to FIG. The output of the normal sensor 34 is, as described above, the transport number “0” to “76” in the transport path (1).
, The transport path 2 is dark between “0” and “152”. Using this information, the difference in the transport path speed is calculated, and 180 pulses (80 × 2 + 20) are shifted by a distance of the sensor 35 from the sensor 34 viewed from the transport path (2), and the sensor output changes from dark to light. By setting the timing to 256 pulses (180 + 200/400 × 152), information on the dummy sensor can be obtained. Note that if the sensor fails, it will not go down.
This is for the same reason as in the first embodiment.
