Embodiments of the present invention will be described below with reference to FIGS.
First, FIG. 1 shows a schematic side view of a banknote recognition apparatus. The banknote identification apparatus 1 is mounted on a vending machine or a money changer and performs a denomination determination and an authenticity determination of an accepted banknote. .
In this banknote identification device 1, a banknote insertion slot 2 for receiving banknotes, a banknote receiving roller 4 for receiving and discharging banknotes arranged at a plurality of locations in the banknote transport path 3, and checking each identification element from the banknotes. A banknote recognition sensor 5, a banknote holding section 6 for temporarily storing received banknotes, a drive section for driving the banknote transport roller 4, a storage section and a timer (not shown) for controlling each component such as the banknote identification sensor 5. The control part 7 which has is equipped.
In this configuration, the banknote inserted into the banknote insertion slot 2 is carried into the inside by a banknote transport roller 4 provided in the banknote transport path 3 and is stored as a banknote if it is determined to be a genuine note when passing through the banknote identification sensor 5. The main control unit 7 performs denomination determination, authenticity determination, and retry processing of the banknote while the banknote passes through the banknote transport passage 3.

The main controller 7 is set in advance with the number of retries for re-identifying banknotes, so that the banknote identification sensor 5 can determine the authenticity of the banknotes even when the banknotes are discharged in the retry process of banknote identification. It is something to control.
Moreover, the installation location of the banknote identification sensor 5 is in a positional relationship between the banknote insertion slot 2 and the banknote identification sensor 5 so that the banknote is not discharged to the banknote insertion slot 2 even during the retry process of banknote identification. Arranged.
The main control unit 7 of the banknote recognition apparatus 1 and an external control device such as a vending machine or a money changer are connected by a communication means (not shown) for notifying the authenticity determination result of the banknote.
In this configuration, the bill retry process will be described with reference to the flowchart of FIG.
First, in the standby state, it is determined whether or not a bill is inserted (step S1). When a bill is inserted into the bill insertion slot 2 and insertion of a bill is detected by a sensor (not shown) (step S1: YES), the main control unit. 7 starts to take in the banknotes by driving the banknote transport roller 3 to rotate forward (step S2). Next, it is determined whether the bill to be conveyed has passed the bill identification sensor 5 (step S3), and if the bill has passed the bill recognition sensor 5 (step S3: YES) The obtained signal is input to the main control unit 7, and after digital conversion, the authenticity of the banknote is determined, and it is determined whether or not the inserted banknote is a true note (step S4). As a result, if it is determined that it is not a true bill (step S4: NO), it is determined whether the identification pass flag is set (step S5), and if it is determined that the identification pass flag is not set (step S5). : NO), the main control part 7 drives the banknote conveyance roller 3 in the reverse direction to start returning the banknotes (step S6).

It is determined whether or not the bill conveyed in reverse is passed through the bill recognition sensor 5 (step S7), and if the bill passes through the bill recognition sensor 5 (step S7: YES), it is obtained while passing through the bill recognition sensor 5. The received signal is input to the main control unit 7, and after the digital conversion, the authenticity of the banknote is determined, and it is determined whether or not the banknote is a true bill even during the return process (step S8).
If it is determined whether the bill is a genuine bill during the bill return process or not (step S8: NO), it is then determined whether the number of retries is a predetermined number or more (step S9). . In this embodiment, if the predetermined number of times is set to 3 and the number of retries is not 3 or more (step S9: NO), it is added to the memory of the number of retries (step S10), and step S2 The bill conveyance roller 3 is normally driven to return to the processing for starting the bill taking-in.

In this way, the processing of steps S2 to S10 is repeated, and if the number of retries is 3 or more in step S9 (step S9: YES), the banknote return operation is continued, and for the first time at this point A banknote is discharged | emitted to the position which can take out a banknote from the insertion port 2 (step S11).
If it is determined in step S8 that the bill is a genuine note during the bill return process (step S8: YES), an identification pass flag is set (step S12). Return to S2.
It is determined whether or not the banknote to be conveyed has passed the banknote identification sensor 5 (step S3) and the banknote has passed the banknote identification sensor 5 (step S3: YES). A signal obtained while passing through the sensor 5 is input to the main control unit 7, and after the digital conversion, the authenticity of the banknote is determined, and it is determined whether or not the inserted banknote is a true bill (step S4). . As a result, when it is determined that it is not a true bill (step S4: NO), it is determined whether the identification pass flag is set (step S5). In this case, since the identification pass flag is set (step S5) (S5: YES), the banknote is conveyed to the banknote holding unit 6 (step S13).

As described above, when it is determined that the bill is a true bill, the bill is taken as a true bill.
On the other hand, if it is determined that the bill is a true bill in the first capture (step S4: YES), the bill is conveyed to the bill holding unit 6 (step S13).
In this way, it is possible to perform the retry process in a short time by performing the authenticity determination of the banknote even at the time of the retry process, and by returning the banknote to the position where the banknote can be taken out only at the time of the last return, It also reduces discomfort and shortens the retry time.
Note that the authenticity of bills is always determined during forward conveyance and reverse conveyance, but if it is determined to be a true bill during reverse conveyance, it is taken in without authenticity during the next forward rotation. In this case, the retry process can be performed earlier.

It is a schematic side view of the banknote identification device which shows embodiment of this invention. It is a flowchart which shows operation | movement of embodiment of this invention.
