The superimposition conveyance detection part 263 performs the following processes using image information, transmission information, thickness information, and short length information, and detects the superimposition conveyance of the banknote Q, and the number of sheets stacked.

15 and 16 are flowcharts showing the detection processing of overlapping conveyance of banknotes.

[Step S1] The transmitted light amount detecting unit 263a of the overlapping conveying detecting unit 263 compares the obtained transmission information with the transmission reference information 211 held in the data unit 210 beforehand. The transmitted light amount detecting unit 263a determines whether the transmitted information corresponds to the indeterminate transmission region of the transmission reference information 211. If it corresponds to the indeterminate transmission region, the process proceeds to step S11, and if it does not correspond to the indeterminate transmission region, the process proceeds to step S2.

[Step S2] The transmitted light amount detecting unit 263a determines whether the acquired transmission information corresponds to one piece of the predetermined transmission region of the banknote of the transmission reference information 211.

[Step S7] The transmitted light amount detecting unit 263a detects that the number of stacked sheets of the bills Q of the obtained transmitted information is three, and ends the detecting process.

[Step S8] The transmitted light amount detection unit 263a detects an error and ends the detection process.

[Step S11] The thickness detecting unit 263b of the overlapping conveying detecting unit 263 compares the obtained thickness information with the thickness reference information 212 held in the prior data unit 210. First, the thickness detection part 263b determines whether the thickness information acquired has the thickness corresponding to one banknote. If there is a thickness corresponding to one sheet, the flow proceeds to step S12. Otherwise, the flow proceeds to step S21.

[Step S12] The thickness detection unit 263b further determines whether or not the thickness information acquired has a thickness corresponding to two bills. If there is a thickness corresponding to two pieces, the process proceeds to step S13, otherwise, the process proceeds to step S15.

[Step S13] The thickness detecting unit 263b further determines whether or not the acquired thickness information has a thickness corresponding to three bills. If there is a thickness corresponding to three pieces, the process proceeds to step S14. Otherwise, the process proceeds to step S17.

[Step S14] The thickness detecting unit 263b detects that the number of stacked sheets of bills Q of the obtained thickness information is three, and ends the detecting process.

[Step S16] The thickness detecting unit 263b detects that the number of stacked sheets of bills Q of the obtained thickness information is two, and ends the detecting process.

[Step S17] The short length detection unit 263c further detects the short length of the banknote Q from the image information subjected to the image processing, and compares it with the length reference information 213 held in the prior data unit 210. It is determined whether the length is 2L or more. If it is 2L or more, the process proceeds to step S14. If it is not 2L or more, the process proceeds to step S16.

[Step S18] The thickness detection unit 263b further determines whether or not the acquired thickness information has a thickness corresponding to five bills. If there is a thickness corresponding to five sheets, the process proceeds to step S19, otherwise, the process proceeds to step S20.

[Step S19] The thickness detecting unit 263b detects that the number of stacked sheets of bills Q of the obtained thickness information is three, and ends the detecting process.

[Step S20] The thickness detecting unit 263b detects an error and ends the detecting process.

[Step S21] The thickness detection unit 263b further determines whether or not the acquired thickness information has a thickness corresponding to two bills. If there is a thickness corresponding to two pieces, the process proceeds to step S22, otherwise, the process proceeds to step S24.

[Step S22] The thickness detection unit 263b further determines whether or not the acquired thickness information has a thickness corresponding to four sheets. If there is a thickness corresponding to four sheets, the process proceeds to step S14. Otherwise, the process proceeds to step S23.

[Step S23] The thickness detecting unit 263b detects that the banknote Q of the obtained thickness information is one sheet, and ends the detecting process.

[Step S24] The thickness detecting unit 263b detects an error and ends the detecting process.

In this way, the overlapping conveyance of the banknote Q detected by the overlapping conveyance detecting unit 263 and the number of stacked sheets thereof are transmitted to the counter 264.

When the counter 264 acquires information indicating the number of stacks of bills Q, the following processing is performed to update the number of bills stored in the stacker in the bill processing apparatus 200.

It is a flowchart which shows the update process of a banknote number.

[Step S31] The counting unit 264 determines whether the number of stacked sheets of banknotes Q detected by the stacker determined in advance by the overlapping conveyance detecting unit 263 is three. In the case of three sheets, the process proceeds to step S32.

[Step S32] The counter 264 takes three differences from the predetermined number of stacks of stackers held in the banknote information storage unit 290, and updates the information on the number of stacks of bills in the stacker.

[Step S33] The counting unit 264 determines whether or not the number of stacked sheets of bills Q detected by the overlapping conveyance detecting unit 263 is two. In the case of two sheets, the process proceeds to step S34. In the case of two sheets, the process proceeds to step S35.

[Step S34] The counting unit 264 takes two differences from the predetermined number of stacks of stackers held in the bill information storage unit 290, and updates the information on the number of stacks of bills in the stacker.

[Step S35] The counting unit 264 updates the information on the stored number of bills in the stacker by taking one difference from the predetermined number of stored stackers held in the bill information storage unit 290.

[Step S36] The counting unit 264 determines whether or not the number of banknotes designated by the customer's operation input coincides with the number of banknotes Q drawn from the predetermined stacker. If there is a match, the update process ends, and if there is no match, the process proceeds to step S37. In addition, the stacking number of banknotes superimposed and conveyed is not included in the designated banknote number.

[Step S37] The counter 264 feeds out the bill Q from the predetermined stack.

In this way, the bill handling apparatus 200 can accurately detect the number of stacked sheets even when the bills Q drawn out from the bill handling apparatus 200 are complicatedly stacked. In addition, the number of banknotes in the banknote processing apparatus 200 can be managed.

Hereinafter, detection of a banknote will be described with specific examples.

(Example 1)

When the withdrawal of one 1,000 yen bill (not shown) is requested by a customer's operation input, when two banknotes drawn from the 1,000 yen stacker overlap and the uppermost banknote is folded back in the long length direction ( For example, see FIG. 10).

First, the banknote detector 220 detects the conveyance of the conveyance path 234 of the banknote drawn out from the 1,000 yen stacker, and notifies the CPU 260 of the detection of the banknote.

An operation command is transmitted by the control unit 261 of the CPU 260.

When the sensor unit 230 receives an operation command, the front surface of the banknote conveyed by the optical sensor 231 is read, and the thickness of the banknote is detected by the thickness sensor 232.

The image signal and the thickness signal generated by the sensor unit 230 are amplified by the amplifier 240, and the amplified image signal and the thickness signal are converted into image information and thickness information of the digital information by the converter 250.

The image processing unit 262 of the CPU 260 normalizes the image information and the thickness information by image processing. In addition, the thickness information of the banknote of Example 1 has the information (FIG. 10 (B)) which shows thickness 2T and thickness 4T.

Transmission light amount detection part 263a of superposition conveyance detection part 263 can obtain the transmission information which shows the transmission light amount of the banknote conveyed from normalized image information.

In addition, the detection processing is performed by the overlapping conveyance detecting unit 263 according to the flowcharts shown in FIGS. 15 and 16.

The transmitted light amount detection unit 263a compares the transmission information with the transmission reference information 211 (FIG. 5) held by the prior data unit 210. In this case, the transmission information of the conveyed banknote corresponds to an indeterminate transmission region.

The thickness detection unit 263b compares the thickness information with the thickness reference information 212 held by the prior data unit 210. In this case, since the banknotes conveyed have the information which shows thickness 2T and thickness 4T, the conveyed banknotes are conveyed superimposed and it detects that 3 sheets are stacked.

The counting unit 264 takes three differences from the number of sheets of the 1,000-yen stacker held in the banknote information storage unit 290, and updates the information on the number of sheets of the 1000-yen stacker. In addition, the conveyed banknote is conveyed to a reject stacker. In addition, the counter 264 feeds out the bills from the 1,000 yen stacker until one bill specified by the customer is drawn out.

(Example 2)

When the withdrawal of one 10,000 yen bill (not shown) is requested by the operation input of the customer, there are two places where the banknotes drawn from the 10,000 yen stacker shift three banknotes back and forth in the conveying direction. The case (for example, see FIG. 11) will be described.

First, the banknote detection part 220 detects conveyance of the conveyance path 234 of the banknote drawn out from a 10,000 yen ticket stacker, and notifies CPU 260 of detection of a banknote.

An operation command is transmitted by the control unit 261 of the CPU 260.

When the sensor unit 230 receives an operation command, the front surface of the banknote conveyed by the optical sensor 231 is read, and the thickness of the banknote is detected by the thickness sensor 232.

The image signal and the thickness signal generated by the sensor unit 230 are amplified by the amplifier 240, and the amplified image signal and the thickness signal are converted into image information and thickness information of the digital information by the converter 250.

The image processing unit 262 of the CPU 260 normalizes the image information and the thickness information by image processing. In addition, the thickness information of the banknote of Example 2 has the information (FIG. 11 (B)) which shows thickness T and thickness 2T.

Transmission light amount detection part 263a of superposition conveyance detection part 263 can obtain the transmission information which shows the transmission light amount of the banknote conveyed from normalized image information.

In addition, the detection processing is performed by the overlapping conveyance detecting unit 263 according to the flowcharts shown in FIGS. 15 and 16.

The transmitted light amount detection unit 263a compares the transmission information with the transmission reference information 211 (FIG. 5) held by the prior data unit 210. In this case, the transmission information of the conveyed banknote corresponds to an indeterminate transmission region.

The thickness detection unit 263b compares the thickness information with the thickness reference information 212 held by the prior data unit 210. In this case, the banknote conveyed has the information which shows thickness T and thickness 2T as mentioned above.

In addition, the short length detection unit 263c compares the short length information indicating the short length of the bill with the length reference information 213 held in the prior data section 210, and detects that the short length of the bill is 2L or more. .

For this reason, the banknotes conveyed are overlapped and conveyed, and it is detected that 3 sheets are stacked.

The counting unit 264 takes three differences from the stored number of the 10,000 yen book stacker held in the banknote information storage unit 290, and updates the information of the stored number of the 10,000 yen book stacker. In addition, the conveyed banknote is conveyed to a reject stacker. In addition, the counter 264 feeds out the bills from the 10,000 yen bill stacker until one bill specified by the customer is drawn out.
