Description

  The present invention relates to a paper sheet identifying method and a paper sheet identifying apparatus, and more particularly to a banknote identifying method and a banknote identifying apparatus that can easily select the type of banknote to be identified.

  The bill discriminating device is used in various labor-saving devices such as vending machines, automatic change machines, and game machines, and includes an entrance for inserting bills, an entrance sensor that is provided at the entrance and detects insertion of bills, and inserted from the entrance. A transport device that transports the bills along the transport passage, a discrimination sensor provided adjacent to the transport passage, and a discrimination control circuit that is connected to the inlet sensor and the discrimination sensor and controls the motor of the transport device. ing. The discrimination sensor includes an optical sensor that detects an optical feature that forms a light / dark pattern or a transmitted light pattern of a banknote, or a magnetic sensor that detects a magnetic feature that forms a magnetic pattern by a component of ink printed on the banknote. .

  When a bill is inserted from the entrance, the entrance sensor detects the insertion of the bill and sends a detection signal to the discrimination control circuit. Thereby, a discrimination control circuit drives the motor of a conveyance apparatus, and takes in a banknote into the inside of a banknote identification apparatus along a conveyance path. When the bill passes through the transport path, the discrimination sensor detects the optical and magnetic features of the bill and sends a detection signal to the discrimination control circuit. The discrimination control circuit Judgment of authenticity. When the discrimination control circuit determines that the inserted banknote is a genuine banknote, the process proceeds to the next process such as product delivery or game start. Return to the entrance.

  The discrimination control circuit includes a ROM (read only memory) that stores an operation program for determining an operation sequence of the banknote discriminating device, and is similar to the optical pattern and magnetic pattern of domestic banknotes, the optical pattern and magnetic pattern of foreign banknotes, and banknotes. A plurality of types of banknote data including coupons and securities distributed in a specific area are also stored in the ROM. Therefore, when using the bill validator at a specific location, not only is it necessary to use all the bill data stored in the ROM, but bills corresponding to the bill data that is not subject are inserted into the entrance. It is necessary to return the bill to the entrance without receiving it. As described above, a function for selecting a paper sheet to be judged to be receivable or rejectable is necessary for the bill validator.

  Conventionally, when determining the type of banknote returned by the banknote discriminating device, the same number of dip switches are installed on the panel for each banknote to be handled, and connected to the discrimination control circuit, and the dip switch is turned on and off separately. Decided to receive or return seeds. For example, even if a banknote of the same denomination as the type set to be unreceivable by switching the dip switch on is inserted into the entrance, the banknote discrimination device does not receive this banknote.

  As described above, when setting the receipt money type, the same number of dip switches as the kind of receipt money type are required, which disadvantageously increases the number of parts. When the types of bills to be received increase, it is difficult to increase the number of switches arranged in a limited space, and there is a problem that a large setting change is necessary.

  Therefore, an object of the present invention is to provide a paper sheet identification method and a paper sheet identification apparatus that can easily select the type of paper sheet to be identified.

  It is an object of the present invention to provide a paper sheet identification method and a paper sheet identification apparatus that can easily set the type of paper sheet that is rejected or accepted.

  The paper sheet identification method according to the present invention comprises a discrimination control circuit (15) in response to an output of an inlet sensor (40) for detecting a paper sheet inserted into an inlet (13) of a paper sheet identification device (10). To drive the transport device (15) and transport the paper sheet inside the paper sheet identification device (10) along the transport path (26), and the optical or magnetic characteristics of the transported paper sheet Is detected by the paper sheet sensor (16), and the determination control circuit (50) of the paper sheet identification device (10) is preliminarily stored in the type storage means (60) by the mode switching means (56). The paper sheet sensor (16) detects the optical characteristic or magnetic characteristic when the mode is switched to the selection mode for selecting the type to be received or the type to be returned and the processing switching means (43) is in the reception mode. When the discrimination control circuit (50) determines that the leaf is a true banknote, the type storage means (60) selects and stores the paper as the type for receiving the paper. After that, the determination control circuit (50) is a mode switching means for reversing the conveying device (15) and returning the paper sheet to the entrance (13) and from the selection mode to the identification mode for judging the authenticity of the paper sheet.

Is driven by a transfer pulley 30.

FIG. 2 shows an electric circuit diagram used for the bill validator 10. This electric circuit has a determination control circuit 50 for determining the authenticity of the banknote from the output signal of the paper sheet sensor 16 and controlling the transport device 15. Each input terminal of the determination control circuit 50 is connected to the inlet 13. Entrance sensor 40 for detecting the inserted bill, optical sensor 41 for detecting the optical feature of the bill to be transported, magnetic sensor 42 for detecting the magnetic feature of the bill to be transported, and switching as processing switching means The switch 43 is connected. Also, a ROM (read-only memory) 52 as identification data storage means for storing identification data of different types of banknotes and an E ² PROM (nonvolatile memory) 60 as type storage means are stored in advance. Dip as mode switching means that can be switched between an on / off state for switching the determination control circuit 50 between a selection mode for selecting the type to be returned or received among the types and an identification mode for determining the authenticity of the paper sheet When the judgment control circuit 50 identifies the banknote inserted into the inlet 13 in a state where the judgment control circuit 50 is switched to the selection mode by switching the switch 56 and the dip switch 56 to ON, it is the same as the type of the banknote. An E ² PROM (type storage means) 60 that stores the rejection or acceptance of the receipt of a type of banknote is a judgment control circuit 50. Each output terminal of the determination control circuit 50 is provided in the identification unit 20 and transports the banknote along the transport path 12, and is provided in the transfer device 24 and transports the banknote along the transport path 26. A transfer motor 34 for transferring to the outlet 26b, an alarm provided in the vicinity of the inlet 13 and lit when in the selection mode, and flashing for a certain time to notify the completion of storage when the type of the sheet is stored in the type storage means A light emitting diode 54 as a container is connected. When the changeover switch 43 is on (reception mode), the determination control circuit 50 receives the same type of banknote as the banknote stored in the E ² PROM 60 as the type storage means, but the changeover switch 43 is off (return mode). At this time, the determination control circuit 50 returns the banknote of the same type as the banknote stored in the E ² PROM 60 to the entrance.

  When the process proceeds from step 100 to step 101 and a power switch (not shown) of the bill validator 10 is turned on, the control program of the determination control circuit 50 is initialized at step 102. Next, in step 103, the determination control circuit 50 determines whether or not the dip switch 56 is on. When the dip switch 56 is on, the determination control circuit 50 is in the selection mode, and when the dip switch 56 is off, the determination control circuit 50 is in the identification mode. In the case of the identification mode, the light emitting diode 54 is not lit and the process jumps to Step 105. In step 103, when the selection mode is set, the operator turns on the dip switch 56 to turn on or blink the light emitting diode 54 (step 104), and proceeds to step 105.

  In step 105, the determination control circuit 50 determines whether or not a bill has been inserted into the inlet 13. When a bill is inserted into the entrance 13, the entrance sensor 40 detects the insertion of the bill (step 106), and the determination control circuit 50 drives the transport motor 38 based on the detection signal of the entrance sensor 40. 38 is rotated forward (step 107), and the bill is conveyed inward along the conveyance path 12. Next, in step 108, bill sampling processing is performed, and the optical and magnetic features of the inserted bill are converted into electrical signals by the optical sensor 41 and the magnetic sensor 42, and sent to the determination control circuit 50. Is done.

Subsequently, in step 109, the determination control circuit 50 determines whether or not it is in the selection mode. If in the selection mode, the process proceeds to step 110, and the determination control circuit 50 determines whether or not the inserted banknote is a genuine banknote. When the inserted banknote is a genuine banknote, in step 111, the type of banknote processed by the sampling process in step 108, that is, information on the denomination to be received is stored in the E ² PROM 60, and the light emitting diode 54 is a judgment control circuit. Flashes for a certain time with 50 outputs. At this time, when the changeover switch 43 is on, the E ² PROM 60 stores the same type of banknote as the stored banknote. Thereafter, in step 112, the transport motor 38 is reversed and the bill is returned to the inlet 13 (step 113), and then the operation of the transport motor 38 is stopped (step 114). Next, in step 115, it is determined whether or not a denomination to be further received may be set. When further setting a denomination to be received, the process returns to step 105. The dip switch 56 is switched off, and the determination control circuit 50 is switched from the selection mode to the identification mode. Therefore, the determination control circuit 50 proceeds to step 127 after turning off the light emitting diode 54 in step 116.

In step 109, when the dip switch 56 is in the OFF state and the identification mode is selected, the process proceeds to step 118, and the determination control circuit 50 determines whether or not the inserted banknote is a genuine banknote. When the inserted banknote is a genuine banknote, it is determined in step 119 whether or not the denomination is the same as the denomination stored in the E ² PROM 60 in step 111. Send a reception signal to the machine. Further, in step 121, the transfer motor 34 is rotated forward to convey a genuine bill to the outlet 14, and in step 122, the stacker is operated, and in step 123, the transfer motor 38, the transfer motor 34, and the stacker are operated. Is stopped and the routine proceeds to step 127.

When the banknote cannot be determined to be authentic in steps 110 and 118, or when it cannot be determined that the denomination is the same as the denomination stored in the E ² PROM 60 in step 119, the determination control circuit 50 reverses the transport motor 38 in step 124 to Is returned to the inlet 13 (step 124), the transport motor 38 is stopped, and the process proceeds to step 127.

The embodiment of the present invention can be modified. For example, when the changeover switch 43 is OFF in step 111, the E ² PROM 60 stores the banknote of the same type as the stored banknote as being returned. As shown in FIG. 4, when it is determined in step 119 that the denomination is the same as the denomination stored in step 111, the process proceeds to step 124. In step 124, the transport motor 38 is reversed and step 125 is performed. Return the banknote at Conversely, when it is determined that the banknote is of a denomination different from the denomination stored in step 119, the banknote may be received in step 120.

  Instead of the DIP switch 56, a normal switch, an infrared transmitter / receiver, and a radio transmitter / receiver can be used as mode switching means. Although an example in which the light emitting diode 54 is used as an alarm device has been shown, a light emitting element such as a plurality of light emitting diodes having different emission colors or an acoustic alarm device such as a buzzer may be used. Although the embodiment of the present invention has been described with respect to the banknote discriminating apparatus, it is obvious that the present invention can be applied to other paper sheets such as coupons and securities other than banknotes.
