Is stored in the reject pocket 43a or the stacker 46a.

In the above configuration, the bill discriminating apparatus 10 according to the present embodiment
The operation sequence will be described with reference to the flowchart shown in FIG.

In step 51 from the start of step 50, the reading control circuit 20 determines whether or not the start switch 34 has been turned on. When the start switch 34 is off, the process returns to the start. When the start switch 34 is turned on, the process proceeds from step 51 to step 52. When the detection switch 35 detects the banknote 14 stored in the hopper 11 in step 52, the read control circuit 20 sends an output to the hopper dispensing circuit 40 and supplies the banknote 14 from the hopper 11 to the transport device 15. At the same time, the read control circuit 20 applies an output to the motor drive circuit 31 to drive the transport device 15 (step 53). As a result, the transfer device 15 is
The banknote 14 is moved along the transfer passage from to the outlet 13.
When the leading end of the bill 14 has passed through the optical sensor 24, the readout control circuit 20 starts counting the feed amount of the bill 14. When the bill 14 passes through the optical sensors 24 and 25 and the magnetic sensor 26, the optical sensors 24 and 25 and the magnetic sensor 26 detect the shape, the optical characteristics and the magnetic characteristics of the bill 14, respectively, and perform readout control. The bill is sent to the circuit 20 (step 54), and the bill discriminating means in the read control circuit 20 outputs the bill 14 while the bill 14 is moving.
The denomination and authenticity of the

The read control circuit 20 that counts the feed amount of the bill 14 determines the time when the code display area 18 printed on the bill 14 passes through the image reader 17, and when the code display area 18 reaches just before the image reader 17, The moving speed of the bill 14 is reduced via the motor drive circuit 31 (step 55). When the motor 30 is a stepping motor, the transport speed of the bills 14 can be reduced by reducing the pulse rate sent to the motor drive circuit 31. Alternatively, the motor drive circuit
By changing the power applied to 31 as an analog amount, it is also possible to reduce the transport speed of bills 14.

When the code display area 18 printed on the bill 14 passes through the image reader 17, the reading control circuit 20 sends an output to the image reader driving circuit 41,
Activate 17 (step 56). Image reader 17 is a banknote
The image of the code display area 18 printed on 14 is converted into an electric signal. At this time, in step 57, the reading control circuit 20 checks the transport direction of the bill 14 from the output of the discrimination sensor 16, and if the bill 14 is placed in the hopper 11 in the opposite direction, the output of the image reader 17 in step 58 After the conversion, in step 59, the denomination and the sign display area of the banknote 14 are displayed.
The 18 images are stored in the storage means 32. When the bill 14 is conveyed in the predetermined direction in step 57, the process proceeds directly from step 57 to 59, and the output of the image reader 17 is stored in the storage means 32 as it is.

Next, in step 60, the read control circuit 20 determines the authenticity of the bill 14. If the bill 14 is a true bill, it is determined in step 61 whether reading of the entire code display area 18 has been completed. If reading of the entire code display area 18 has not been completed, the flow returns to step 59. When reading of the entire code display area 18 is completed, the reading control circuit 20 stops outputting to the image reader driving circuit 41 in step 62,
Deactivate image reader 17. Subsequently, in step 63, the storage means 32 of the read control circuit 20
The output of the image 17 is stored and sent to the printer device 19. The printer device 19 transfers the image (image) of the code display area 18 printed on the bill 14 as it is, based on the output of the reading control circuit 20, and records the type of the bill 14. FIG. 6 shows a recording paper 49 on which an image of the code display area 18 and a denomination 48 are recorded. Date, time,
Information such as the total amount of denominations, the total amount of all denominations, the exchange rate, and the number of payouts is displayed. Information such as date, time, total denomination total amount, total denomination total amount, exchange rate, number of payouts, and the like are automatically displayed by a timer, an arithmetic circuit, and the like built in the reading control circuit 20. The exchange rate is input by the numeric key switch 33.

At the same time, after the code display area 18 printed on the bill 14 passes through the image reader 17, the readout control circuit 20 increases the pulse rate to the motor drive circuit 31 to increase the transport speed of the bill 14. (Step 64). Thereafter, the stacker driving circuit 46 is operated, and the bill 14 is discharged from the discharge port 13 to the lower stacker 46a by the deflector 47 (step 65).

When the reading control circuit 20 does not detect that the bill 14 is authentic in step 60, the reading control circuit 20 erases the content stored in the storage means 32 in step 66, and thereafter, the reading control circuit 20 47 and transport device
The banknote 14 is moved to the reject pocket 43a by driving the 15 reject drive circuit 43. Therefore, when it is determined that the bill is not a genuine bill, the reading control circuit 20 does not operate the printer device 19.

FIG. 7 shows a bill validating apparatus 10 shown as an embodiment of the present invention.
