Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a banknote counting machine that distinguishes the denomination of banknotes loaded in a holder by attracting them to a suction shaft and turning over the banknotes one by one. It is.

"Conventional technology" Conventionally, this type of banknote counting machine was
There is a ``device for discriminating different types of bills in a paper sheet counting machine'' disclosed in Publication No. 69885.

This "different types of bill discriminating device for paper sheet counting machine" distinguishes the denomination of paper sheets (banknotes) loaded in a holder by attracting them to a suction shaft and turning them over one by one.
The total amount can be calculated and displayed or printed.

"Problems to be Solved by the Invention" By the way, in the banknote counting machine configured as described above, counting ends midway when the denomination cannot be determined, and in that case, the denomination must be determined from the beginning again. I had to redo it.

Furthermore, when the denomination is judged again, if the flow rate becomes midway again, the amount of the remaining banknotes is calculated with the abnormally recognized banknote removed, and this amount calculation value is added to the amount of the removed abnormally recognized banknote. The total amount was calculated by adding the monetary values.

Further, in the above-mentioned banknote counting machine, the denomination is determined based on the height of the banknote, and it becomes impossible to determine the denomination for banknotes of the same height, such as current banknotes.

Therefore, it would be better to have a banknote discrimination function that reads the surface pattern of the banknote to determine the denomination type. However, if the banknote surface pattern is used to determine the denomination type, the banknote itself may become dirty or torn. It often becomes impossible to distinguish the denomination, and simply changing the discriminating mechanism of the banknote counting machine as described above will only result in many premature terminations when the denomination cannot be distinguished, and as mentioned above, the denomination discrimination will have to be restarted from the beginning. Doing so was extremely troublesome in terms of operability.

This invention has been made in view of the above circumstances, and includes interrupting the bill turning operation by a suction shaft in the event of an abnormality in discrimination, and at the time of this interruption, confirming the denomination of the abnormally discriminated banknote and inputting the denomination. By doing so, it is possible to automatically resume the banknote flipping and denomination determination operation from the point of interruption.
and a banknote counting machine capable of calculating the total amount of banknotes loaded in the holder based on the denomination information output during the flipping operation of the suction shaft and the denomination information input at the time of interruption. The purpose is to provide the following.

``Means for Solving the Problems'' In order to achieve such an objective, the present invention is designed to distinguish the denominations of banknotes loaded in a holder by attracting them to a suction shaft and turning them over one by one. A banknote counting machine reads the surface pattern of a banknote and compares this surface pattern with pre-stored reference data to determine the denomination of the banknote and output a denomination code. a denomination discrimination function that outputs a discrimination error code; a peeling prevention function that interrupts the bill turning operation by the suction shaft based on the discrimination error code outputted by the denomination discrimination function; When the withdrawal prevention function is interrupted, there is a confirmation function that allows you to check the banknotes that have been identified as abnormal banknotes and input their denominations, and a confirmation input function that allows you to enter and confirm the denomination and enter the denomination. There is a confirmation input function that allows input, and when the denomination is input and confirmed using this confirmation input function, the interruption caused by the flipping prevention function is canceled and the bill flipping and denomination discrimination operation from the point of interruption is resumed. The holder is loaded based on the continuous counting function that restarts automatically, the denomination code output by the denomination discrimination function, and the set denomination code input by the denomination confirmation input function. An amount calculation function is provided to calculate the total amount of banknotes.

"Function" According to the present invention, when a discrimination abnormality code is output when there is an abnormality in the denomination of banknotes, the operation of turning over the banknotes by the suction shaft is interrupted, and
At the time of this interruption, the denomination of the abnormal banknote is confirmed and its denomination code is set (input), so that the banknote flipping and denomination determination operation from the time of interruption is automatically restarted.

Also, based on the set denomination code that is input when entering this denomination confirmation input and the denomination code that is automatically determined and output when the sheets are turned over one by one by the suction shaft and output, the holder is loaded. The total amount of banknotes is calculated.

"Example" The present invention will be described below based on an example shown in FIGS. 1 to 10.

First, the structure of the banknote counting mechanism will be explained according to FIGS. 1 to 3.
By placing banknotes S on the holder 1 and horizontally rotating the holder 1 around the shaft 2, the banknotes S are moved to the counting position shown by the solid line in FIG. 1 or the standby position shown by the chain line in FIG. While rotating the rotary cylinder 3 in the counterclockwise direction in FIG. The banknotes S on the holder 1 are counted while being turned over one by one by applying vacuum pressure to the banknotes, and the banknotes are identified by reading the reflected light of the light rays irradiated onto the surface of the banknotes S from a projector, which will be described later, with a light receiver. The basic configuration is as follows.

The holder 1 has a banknote S on the back side (suction shaft 5
A base plate 1a is provided to support the base plate 1a from the opposite side), and the surface 1b of this base plate 1a is formed in a blackish color so as to reduce the level of reflected light.

On the other hand, an exhaust pipe 13 is connected to the exhaust port 12 of the vacuum pump 8, and the tip of the exhaust pipe 13 blows exhaust gas onto the sides of the banknotes S to facilitate separation of the banknotes S from each other. On the other hand, an exhaust nozzle 14 is provided in the middle of the exhaust pipe line 13 to switch the exhaust to a discharge port 15 when banknotes are not being counted to prevent the generation of noise from the exhaust nozzle 14. A solenoid valve 16 is provided.

In addition, each of the suction shafts 5 has a structure shown in FIGS.
As shown in FIG. 3, a pair of position regulating pieces 5a are fixed. This position regulating piece 5a is connected to the suction shaft 5
The opening 10 of the suction shaft 5 protrudes from the side surface of the suction shaft 5.
When the outside air is sucked through the opening 10 and the bill is attracted to the suction shaft 5, it supports the bill from the side and prevents the bill from falling or folding. It is now possible to prevent In this way, the position regulating piece 5a
, the suction shaft 5 maintains the suction-separated banknote in an upright state, and the banknote is placed in the position where it is detected whether or not double feeding is being carried out (the position Sa where the banknote is suction-separated in FIG. 1). positioning is now performed.

Further, a plurality of actuation pieces 17 made of magnetic material are attached to the outer circumference of the rotary cylinder 3, and each suction shaft 5 is moved to a standby position (opening) depending on whether or not these actuation pieces 17 actuate the magnetic sensor 18. 10 is in the starting position (opening 1
0 is in the position just before directly facing the bill, and the inside of the suction shaft 5 is in a position where it is cut off from the vacuum pump 8.

In addition, in FIG. 3, reference numeral 19 is a counting motor that drives the rotary cylinder 3 via a belt 20;
1 is a pump motor that drives the vacuum pump 8 via a belt 22; 23 is a holder motor that rotates the holder 1; 24A and 24B are
Holder 1 in closed position (position close to suction shaft 5)
This is a holder position detection switch that detects whether the holder is in the open position (a position away from the suction shaft 5).

Further, a separator 25 is provided near the rotary cylinder 3, and this separator 25 is connected to the shaft 26.
The spring 27

The separator 25 has a function (to prevent peeling) by being inserted between a banknote that has already been turned over and a banknote that has not yet been turned over when a banknote of a different denomination is detected, as will be described later. function).

Next, a stamping mechanism for stamping a confirmation stamp on a bundle of banknotes will be explained with reference to FIG. 1. 1 is a seal holding member provided in the holder 1, and the seal holding member 30 supports a seal 31 so as to be movable in the direction of the arrow E-L, and the seal holding member 30 supports the seal 31 movably in the direction of the arrow E-L. It is movably supported so as to be close to and away from S. Further, a dial 32 is provided at the base end of the holder 1, and by rotating this dial 32, the seal 31 moves in the direction of the arrow E-L, and the seal 31 is stamped on the seal 31. 31a is aligned with the band seal B.

Further, on the base supporting the holder 1, there is a shaft 33.

1b from the rear to seal the stamping part 3 of the seal 31.
1a is brought close to the band seal, thereby making it possible to stamp the band seal.

Next, a mechanism for detecting double feeding of banknotes turned over by the suction shaft 5 will be described with reference to FIG. 1.

In FIG. 1, reference numerals 37 and 38 respectively indicate a double feed detection lamp and a light-receiving element (these elements constitute a double-feed detection sensor), and reference numeral 39 indicates a light-receiving element. This is a condensing lens that condenses light.

The double feed detection lamp 37 and the light receiving element 3
8 are both provided facing the rotary tube 3 side, and the light beam emitted from the double feed detection lamp 37 is irradiated from a direction crossing the turned-over banknote Sa, and The beam is irradiated to approximately the center of the turned-up portion of the banknote Sa.

And the banknotes that were irradiated with light in this way
The amount of light transmitted through the banknote Sa, that is, the amount of transmitted light, is detected by a light receiving element 38, and further, based on the amount of transmitted light detected by this light receiving element 38, a determination of double feeding is made. That is, if the amount of transmitted light is greater than a predetermined value, normal feeding (single sheet feeding) is determined, and if the amount of transmitted light is less than a predetermined value, it is determined to be double feeding.

Next, a discrimination mechanism for discriminating the denomination and front and back of banknotes will be explained with reference to FIGS. 1 and 2.

In the figure, the reference numeral 40 indicates a light projector that irradiates light onto the stacked frontmost banknotes Sb.
1 is a light receiver (detection element) that receives the reflected light of the light irradiated onto the banknote Sb from the projector 40, and the light beam emitted from the projector 40 is indicated by a chain double-dashed line on the banknote Sb. The area including area E is irradiated.

The light receiver 41 also includes an area sensor 42 that generates an electrical signal according to the pattern on the surface of the banknote.
and a condensing lens 43 that condenses reflected light from the banknote Sb onto the area sensor 42.
The area sensor 42 is a two-dimensional sensor in which a large number of line-shaped image sensors are arranged in a direction perpendicular to the line, and is operated by a trigger signal issued from a discrimination control circuit 46 to be described later. The amount of reflected light at a specific position (line or coordinate) in area E is converted into an electrical signal, and a waveform signal corresponding to the pattern on the banknote surface is output. In other words, the area sensor 42 has its horizontal direction corresponding to the X coordinate of area E, and its vertical direction corresponding to the Y coordinate of area E.
Depending on the correspondence with the XY coordinates, for example, the surface pattern (line data) in area E is Y=1,
You can read by specifying the line as Y=3,
Furthermore, the read area data is stored in the ROM64.
(described later), it is possible to determine the denomination and front and back of the banknote Sb (details will be described later).

Next, as shown in FIGS. 4A and 4B, a counting control circuit 45 (a flip-up prevention function, a confirmation input function, a continuous counting function, an amount calculation function) and a discrimination control circuit 46 operate the counting mechanism and discrimination mechanism, respectively. (Denomination discrimination function) will be explained.

That is, the counting control circuit 45 has a ROM 47 that stores a counting control program (see FIGS. 5 and 6) to be described later, and writes and reads various data according to the program stored in the ROM 47. It is composed of a RAM 48 that performs this, and a CPU 49 that controls these. Furthermore,
The CPU 49 includes, via an input side I/O port 50 and a receiver 51, a start switch 52 for instructing the start of counting operation, a detection mode switch 53 for discriminating the denomination and double feed, and a detection mode switch 53 for discriminating front and back sides. The front/back mode switch 54 is connected, and other devices such as holder position detection sensors 24A and 24B, rotary cylinder position sensor 18, pressure sensor 11, clear switch, etc., which detect whether the holder 1 is in the closed position or the open position, are connected. Operation switches 55 are connected to each.

In addition to the clear switch, the operation switch 55 includes a mode selection switch for appropriately selecting modes such as count addition, designation (batch), review (check), stamping, and amount calculation, as will be described later. When counting is interrupted when the count ends abnormally, there are 10,000, 5,000, and 1,000 notes buttons for inputting denomination confirmation for banknotes with an abnormal denomination, and a confirmation button for confirming this discrimination confirmation input. There are also confirmation switches (both switches are not shown) such as (also used to confirm the denomination).

The modes selected by the mode selection switch, such as count addition, designation (batch), re-examination (check), stamping, and amount calculation, are based on the above-mentioned denomination and double feed discrimination. The detection mode switch 53 and the front/back mode switch 54 for performing front/back discrimination are in a relationship as shown in the table of FIG. 4B.

In other words, when selecting the count addition mode, specification mode, or review mode among the mode selection switches, each time you select one of these modes, you must specify whether the detection mode switch 53 is to be turned ON or OFF. (However, when the count addition mode is selected, the detection mode switch 53 is automatically set.
Also, when the stamping mode is selected from the mode selection switch, the detection mode switch 53 is automatically set to ON, and the detection mode switch 53 is automatically set to ON by the operator.
The work of specifying is now omitted.

Furthermore, when the stamping mode is selected, the detection mode switch 53 is turned on as described above.
is automatically specified as ON, but only once
It is now possible to specify OFF. In other words,
Select the stamping mode and turn the detection mode switch 53
When OFF is specified, (1) when the banknotes are counted once, (2) the detection mode switch is turned OFF.
If you do not press the start switch 52 within 10 seconds after specifying, (3) turn on the detection mode switch 53.
When specified, the detection mode switch 53
is automatically released from the OFF mode to the original ON mode.

Furthermore, when the amount calculation mode is selected, the detection mode switch 53 is automatically designated ON, and it is impossible to designate this detection mode switch 53 OFF.

On the other hand, the above-mentioned count addition mode, specification mode,
In the review mode and stamping mode, the front/back mode switch 54 can be turned on or off only while the detection mode switch is set to ON, but in the amount calculation mode, the front/back mode switch 54 is automatically turned on. is designated as OFF, and it is impossible to designate this front/back mode switch 54 as ON.

Of the various modes selected by the mode selection switch, "counting and addition" is used to accumulate and add the banknote count and count value for each count, as will be explained in the flowchart of FIG. (described later in step 144 of FIG. 6), "designation (batch)" means to specify the banknote count as, for example, 50 banknotes, and when the count of 50 banknotes is completed, the separator 25 is
This is a mode in which the banknotes are operated to separate counted banknotes from uncounted banknotes (described later in step 110 in Figure 6), and "check" is a mode in which the banknotes are checked to see if there are a predetermined number of banknotes in the bundle. This is a mode to confirm whether or not the banknote is valid (described later in step 140 in Fig. 6).Furthermore, "sealing" is a mode in which after revalidating the banknote, if the revalidation is correct, a seal is placed on the band. Yes (6th
``Amount Calculation'' is a mode that calculates and displays the total amount of all banknotes loaded in the holder (described later in step 142 of the figure).
146).

On the other hand, the start switch 52 shown in FIG.
In this embodiment, the pushbutton 60 (see FIG. 1) provided on the holder 1 constitutes a pushbutton 60, but for example, a sensor (not shown) that detects that a banknote S is loaded in the holder 1 can be activated. switch 52
May be used as

Further, the CPU 49 is connected to a solenoid (printing solenoid) 35, a lamp consisting of a double feed detection lamp 37 or a projector 40, a holder motor 23, and a counting motor 19 via an output side I/O port 61 and a driver 62. , pump motor 21, solenoid valve 16, batch solenoid 28, and bill counter operation panel (not shown)
A display section 63 is connected to the display section 63 for displaying the number of banknotes, presence or absence of an abnormality, etc.

On the other hand, the discrimination control circuit 46 has a ROM 64 that stores discrimination control programs (see FIGS. 7 and 8), and writes and reads various data according to the programs stored in the ROM 64. RAM65 to perform and control these
It is composed of a CPU 66. Furthermore, the above
An area sensor 34 is connected to the CPU 66 via an output I/O port 70 and a drive circuit 71, and the output of this area sensor 34 is connected to an amplifier 72,
A/D converter 73, input side I/O port 74
It is designed to be input to the CPU 66 via.

Note that from the drive circuit 71 to the area sensor 34
The drive signal supplied to the banknote is composed of an X-axis drive signal and a Y-axis drive signal, and by outputting these X-axis drive signals and Y-axis drive signals, the surface pattern at a specific position in area E of the banknote is determined. (area data)
is now read out. When extracting surface pattern data in area E, first output a Y-axis drive signal to determine the Y coordinate of area E (see Figure 2).
The X coordinate of area E may be determined by outputting an X-axis drive signal. For example, set Y to 1 and read the data in area E as line data (X, 1), set Y to 3 and read the data in area E as line data (X, 3), and read these data. The output multiple line data (X, 1), (X, 3), etc.
The data may be compared with reference data stored in the RAM 65 (the X-axis and Y-axis of the drive signal correspond to the X-axis and Y-axis of area E shown in FIG. 2, respectively).

On the other hand, similar to the area sensor 34, double feed detection sensors 37 and 38 are connected to the A/D converter 73 via an amplifier 78. Further, an analog switch 7 operated by a switching signal from the output side I/O port 70 is connected between the amplifiers 72 and 78 and the A/D converter 73.
These analog switches 79 and 80 allow the output signal of either the area sensor 34 or the double feed detection sensors 37 and 38 to be sent to the A/D converter 73. It's summery.

Further, the CPU 49 of the counting control circuit 45 and the CPU 66 of the discrimination control circuit 46 are connected to each other via data transfer I/O ports 81 and 82, and can mutually convert data and operate in conjunction. It is configured as follows.

Hereinafter, the contents of the program stored in the ROM 47 of the counting control circuit 45 will be explained along with the operation of the banknote counting machine with reference to FIGS. 5 and 9.

Note that SN in FIG. 5 indicates step N in the following explanation, and Tn in FIG. 9 indicates timing Tn in the following explanation.

(a)◇Counting control operation 1 (see Figures 5 and 9) <Step 1> Power on <Step 2> Based on the output signals of the holder position detection sensors 24A and 24B, check whether the holder 1 is in the open position or not. If the answer is NO, drive the holder motor 23 to set the holder 1 to the open position (step 3).
If YES, proceed to the next step 4.

<Step 4> Based on the presence or absence of an output from the rotary cylinder position sensor 18, it is determined whether the suction shaft 5 is in the standby position (that is, the position where the suction shaft 5 directly faces the banknote),
If NO, the counting motor 19 is driven at low speed and the suction shaft 5 is set to the standby position (step 5).
If YES, proceed to the next step 6.

<Step 6> Determine whether or not the mode setting switch has been set. If YES, various mode setting operations, such as specified mode (batch mode),
By operating the review mode (check mode) or the stamping mode, the mode in which these operations were performed is memorized (step 50), and if NO, it is assumed that the mode setting operation has not been performed. (The mode is now in counting and addition mode), proceed to the next step 7.

<Step 7> Start signal (ST) from start switch 52
It is determined whether or not the output has been output, and if NO, the process returns to step 6, and if YES, the process proceeds to the next step 8 (timing T ₁ ).

<Step 8> Based on the outputs of the holder position sensors 24A and 24B, it is determined whether the holder 1 is in the closed position or not. If NO, a holder motor drive signal (HMD) is output and the holder motor 23 is is driven to set the holder 1 to the closed position (step 9), and if YES, proceed to the next step 10 (timing T ₂ ).

<Step 10> A pump drive signal (PMP) is output to drive the pump motor 21, and a solenoid valve drive signal (SV) is output to switch the solenoid valve 16 to the exhaust nozzle 14 side.

<Step 11> Determine whether the suction shaft 5 is at the starting position,
If NO, count motor drive signal (CMD)
is output, the counting motor 19 is driven in the reverse direction at low speed to set the suction shaft 5 to the starting position (step
12), and in the case of YES, proceed to the next step (timing T ₃ ).

<Step 13> Wait for the pressure judgment signal (VSW) to be output, that is, wait for the vacuum pressure in the suction pipe 7 to rise to a predetermined value, and then proceed to the next step 14 (timing T _Four ).

<Step 14> When the pressure discrimination signal (VSW) is output (step 13), the counting motor drive signal (CMD) is output.
is output, and the rotating barrel 3 and suction shaft 5 start rotating.

<Step 15> The suction shaft 5 counts the bills while turning them over one by one, and every time the rotary cylinder position sensor 18 generates a signal (SNS), a trigger signal (TRG) is generated for retrieving the detection data of the area sensor 42. ) is output. Also, at this time, a counting signal (CNT) is output to count (or discriminate) the banknotes (timings _T6 to Tm).

<Step 16> Determine whether or not the pressure judgment signal (VSW) is output, that is, whether the vacuum pressure in the suction pipe line 7 is in a state where it cannot be increased (OFF),
If it becomes OFF (timing Tm ₊₁ ), proceed to the next step 17, or as will be described later, the separator 25 is activated due to a discrimination error, etc., and the suction shaft 5 is prevented from turning over the bill, and counting is interrupted. If so, proceed to step 17.

In other cases (NO), as long as the pressure judgment signal (VSW) is output (ON), the process loops to step 15 and performs the counting operation as described later. conduct.

<Step 17> Stop the counting motor 19 and pump motor 21.

<Step 18> In the same way as Steps 4 and 5 described above, it is determined whether or not the suction shaft 5 is in the standby position, and if NO, the counting motor 19 is driven at low speed to move the suction shaft 5 to the standby position. (step 19),
If YES, proceed to the next step 20.

<Step 20> If the counting ends with YES in Step 16, the count ends abnormally (as described later, the count ends due to a discrimination error, different denominations, or discrepancy between the front and back sides, and excludes cases where the count ends due to the detection of double adhesion). ), and proceed to step 22 only if counting ends due to abnormal termination, and proceed to the next step 21 in other cases.

<Step 21> As described later, it is determined whether the holder open signal is output automatically or by operating the clear button (clear switch) depending on the processing mode, and if YES, the step is executed. The process returns to step 2 (timing Tn), and if NO, the process waits at step 21. When the process returns to step 2 (timing Tn), it is determined whether or not the holder 1 is opened, and the holder motor drive signal (HMD) is output until the holder 1 is opened.

Then, when the holder opens (step 4; timing Tn ₊₁ ), the motor drive signal (HMD) is activated.
At the same time as turning off, a counting motor drive signal (CMD) is output to drive the counting motor 19. When the suction shaft 5 moves to the standby position by driving the counting motor 19, the output of the rotary cylinder position sensor 18 turns ON, and at the same time, the counting motor 19 is stopped (timing Tn _{+ 2} ).

When the suction shaft 5 is stopped at the standby position in this way, it becomes ready to start counting immediately by the next start signal (step 7).
The next preparation is completed.

<Step 22> If counting ends due to an abnormal end, as will be described later, when the operator visually confirms the denomination of the abnormal banknote and operates the confirmation switch, it is determined that continued counting is YES and the step continues. Proceed to 24.

On the other hand, while the confirmation switch is not operated in step 22 (while the continuation count is NO), it is determined in step 23 whether or not the clear button has been operated, and if the clear button has been operated (YES), the step From step 23, the process returns to step 2 in the same manner as step 21 described above, and if step 23 is NO, the process waits in a loop of steps 22 and 23.

<Step 24> In step 24, if the confirmation switch is operated and the continuous counting is determined to be YES, the step
15 and 16, the batch state (a state in which the separator 25 prevents the bill turning operation by the suction shaft 5) caused by the separator 25 that was activated at the time of abnormality is released, and the process returns to step 10 (at timing T2 ₎ . When the pump motor 21 starts driving, the suction shaft 5 is reversed from the standby position to the start position, and after that, the pressure judgment signal (VSW) is output, so that the turning of the banknotes is resumed from the point of interruption. The denomination type determination operation will be automatically restarted.

Next, the counting processing flow in the CPU 49 will be explained with reference to FIG.

In addition, if the detection mode switch 53 is turned off, it is determined that only counting is performed, and
Proceed to the next step 103.

<Step 103> After the start operation is performed and the suction shaft 5 is moved from the standby position to the start position, the process waits in step 103 until the pressure judgment signal (VSW) is output.

Proceed to 108.

<Step 108> Determine whether or not the detection mode switch 53 is turned on. If YES, proceed to step 109; if NO, proceed to step 110.

<Step 109> If a different denomination is detected, if a discrepancy between the two sides is detected in the front/back discrimination mode, if it is determined that there is a discrimination abnormality because it does not match all the standard patterns, or if double adsorption is detected.

<Step 110> Determine whether the batch mode is ON or not. If NO, return to step 106; if YES, proceed to step 111.

<Step 111> The number of banknotes is determined, and if it is determined that the banknote count is less than the predetermined number (NO), the process returns to step 106, and if the banknote count has reached the predetermined number. If it is determined (YES), the batch solenoid 28 is turned ON to separate counted banknotes from uncounted banknotes (step 112), and then a discrimination OFF signal is output (step 113) (this discrimination OFF signal is supplied to the discrimination processing flow as shown by the arrow), and the driving of the counting motor 19 and the pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 are stopped (step 114). Then, proceed to the next step 115.

<Step 115> The cause of turning on the batch solenoid 28 to operate the separator 25 and interrupting the peeling operation by the suction shaft 5 is an abnormality in discrimination, different denominations, or a discrepancy between the front and back sides, as explained in step 20 above. It is determined whether or not the abnormal termination is due to detection, and if the counting is interrupted due to the abnormal termination, the process proceeds to step 160; otherwise, the process proceeds to step 116.

<Step 116> Whether or not a clear operation has been performed to deactivate the separator 25 that was activated during the batch processing described above or when a double adsorption error was detected, or whether there is a residual error set in step 135 or step 148, which will be described later. It is determined whether a clear operation has been performed to cancel the set count mismatch error, and if YES, the process proceeds to step 117.

<Step 117> An open signal (see step 21) is output to holder 1, and this flow ends.

Next, steps 120 to 123 will be explained.

<Step 120> In step 106, the ON-OFF state of the rotary cylinder position sensor output signal (SNS) is detected,
If it is in the ON state, the routine from step 106 to step 110 (or step 111) continues, and when it becomes OFF, this step is executed.
Move to 120. Then, as in step 107, it is determined whether or not the pressure discrimination signal (VSW) is ON, and if the determination is NO, the process proceeds to the next step 130, as in step 107.
A discrimination OFF signal is output (step 130), and the driving of the counting motor 19 and pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 are stopped (step 131). Further, if the output of the pressure determination signal (VSW) is YES, the process proceeds to step 121.

<Step 121> Determine again whether or not the rotary tube position sensor output signal (SNS) has risen. If NO, return to step 120; if YES, output the trigger signal (TRG) and Step 122) (This
TRG is supplied to the discrimination processing flow as shown by the arrow), and after counting the counter CNT by 1 (step 123), the process returns to step 106.

Next, steps 130 to 148 will be explained.

<Step 130> As mentioned above, if the output of the pressure judgment signal (VSW) is not detected in steps 107 and 120,
For example, if the banknotes at the counting position are not picked up or there are no banknotes to be counted, the
An OFF signal is output (this discrimination OFF signal is supplied to the discrimination processing flow as shown by the arrow),
And after stopping the driving of the counting motor 19 and the pump motor 21 and the lighting of the double feed detection lamp 37 and the floodlight 40 (step 131), step 132
Proceed to.

<Step 132> Determine whether or not the detection mode switch 53 is turned on. If NO, proceed to step 140; if YES, proceed to step 133.

<Step 133> If the discrimination routine does not output an end signal (indicated by an arrow) for a certain period of time (step 134), for example, even though the banknotes to be counted have been set, If suction has not been carried out, a flag indicating a residual error is set in a predetermined area of the storage section (RAM 48 or CPU 49) (step 135), and then the process proceeds to the next step 116.

Further, if an end signal is output from the determination processing flow shown in FIG. 7, the process advances to the next step 140.

<Step 140> Determine whether or not the mode setting is set to the number of sheets check mode. If NO, proceed to step 144; if YES, proceed to step 141.

<Step 141> Determine whether the counted value of the banknotes matches the number set in the number of banknotes check mode, and if NO, place a flag indicating a mismatch error in a predetermined area of the storage unit. Step
148), proceed to step 116. Further, if the set number of sheets and the counted value match (YES), the process advances to the next step 142.

<Step 142> Determine whether or not the mode setting is set to stamping mode. If YES, operate the stamping solenoid 35 to stamp the seal (step
143), and if NO, proceed to the next step 144.

<Step 144> Determine whether or not the mode setting is set to addition mode. If YES, add the counting results of the previously counted banknotes and store the addition result in the storage unit (Step 144). 145), and if NO, proceed to step 146.

<Step 146> Determine whether the mode setting is set to amount calculation mode, and if YES, display the total amount of the counted banknotes (step 147), and
If NO, the process advances to step 117 and the counting process ends.

In addition, in the amount counting mode, the step
147, but instead of incrementing the counter CNT by 1 in step 123, the total amount is calculated and displayed based on the denomination code output in step 216, which will be described later. It is also possible to do so.

Next, steps 160 to 181 will be explained.

<Step 160> As mentioned above, in step 115, the batch solenoid 28 is turned ON to operate the separator 25, and the cause of interrupting the peeling operation by the suction shaft 5 is an abnormality in discrimination, a different denomination, or a discrepancy between the front and back sides. In the case of abnormal termination due to detection, it is determined whether or not the mode is monetary counting mode. If YES, the process proceeds to the next step 161; if NO, the process proceeds to step 180.

<Step 161> While suspended in the batch state, the denomination of the abnormal banknote that was last turned over by the suction shaft 5 is visually confirmed, and the denomination corresponding to the denomination of this abnormal banknote is determined. In this step 161, it is determined whether the 10,000-ticket button has been operated, and if YES, a code representing a 10,000-ticket is set (set a flag: step 162 ), if NO, proceed to the next step 163.

<Step 163> In the same way as step 161, it is determined whether the 5,000-note button has been operated, and if the answer is YES, a code representing the 5,000-note button is set (step 164), and if the answer is NO, the next step is executed. Proceed to 165.

<Step 165> As in steps 161 and 163 above, determine whether the 1,000-note button has been operated, and if YES, set a code representing 1,000-notes (step 166), and if NO, proceed to the next step. Proceed to 167.

<Step 167> Determine whether or not the denomination code for the abnormal banknote has been set in any of steps 161, 163, and 165 above, and if YES, proceed to the next step.
Proceed to step 168; if NO, proceed to step 169.

<Step 168> After setting the denomination code for the abnormal banknote, it is determined whether the confirmation button to confirm this has been operated,
If YES, proceed to step 170; if NO, proceed to the next step 169.

<Step 169> If the visually confirmed abnormal banknote is, for example, a paper sheet such as a receipt stuck between banknotes, a clearing operation is required to remove it. , said step 116
Similarly, determine whether the clear button is operated or not,
If YES, the process advances to step 117 to end the counting, and if NO, the process returns to step 161 so that the denomination code for the abnormal banknote can be input.

<Step 170> When the denomination code for the abnormal banknote is set and the confirmation operation is performed, the set denomination code is output in the same way as in step 216 in the discrimination processing flow described later, and in the next step 171, the next denomination code is output. It is cleared for denomination input and proceeds to the next step 172.

<Step 172> If the denomination and code for the abnormal banknote are input in steps 161 to 170,
Alternatively, if the denomination of the abnormal banknote in the different denomination detection mode is confirmed in step 180, which will be described later, that is, if the continuous counting is determined to be YES in step 22, then in step 112, the abnormal banknote is confirmed. Turn off the batch solenoid 28 that was turned on at the end and turn off the separator 25.
The batch state (a state in which the separator 25 prevents the bill turning operation by the suction shaft 5) is canceled, and the process returns to step 101.

Then, the discrimination ON signal and the front/back mode signal (however, only when the front/back mode switch 54 is ON) are outputted, and the double feed detection lamp 37 and the floodlight 40 are turned on (step 102).
Thereafter, the pressure determination signal (VSW) is output, and the banknote peeling and denomination determination operation from the point of interruption is automatically restarted.

<Step 180> If the counting interruption due to abnormal termination in step 115 described above occurs in a mode other than the amount calculation mode, that is, if a banknote of a different denomination from the banknotes that have already been turned over and counted is detected. In the case of the normal different denomination detection mode, which is interrupted when an abnormal banknote is detected, it is checked whether the abnormal banknote is of the same denomination as the banknote that has already been turned over and counted. If YES, proceed to step 172 to enable continuous counting; if NO, proceed to the next step 181.

<Step 181> As in steps 116 and 169, it is determined whether the clear button has been operated or not. If YES, proceed to step 117 to finish counting; if NO, return to step 180. These two steps 180,
The system waits in the loop of 181, and supports input as to whether the abnormal banknote is of a different denomination or not.

Next, the determination processing flow in the CPU 66 will be explained with reference to the time charts of FIGS. 7, 8, and 10.

<Step 200> Start <Step 201> Determine whether the trigger signal (TRG) (indicated by the arrow) is output from the counting routine and select YES.
In this case, proceed to the next step 202.

<Step 202> It is determined whether or not the determination ON signal (indicated by the arrow) has been output from the counting routine. If NO, return to step 201; if YES, turn on the analog switch 80 shown in FIG. Select the output of the double feed detection sensors 37 and 38 to the amplifier 78,
Capture via A/D converter 73, RAM
65 (step 203), step 204
Proceed to.

<Step 204> Based on the error codes set in step 215, step 223, and step 232, it is determined whether there is a mixture of different denominations, there is a discrepancy between the front and back sides, and there is an abnormality in discrimination (mixture of abnormal banknotes). Detection of mixture of denominations, discrepancy between front and back, and discrimination abnormality are arranged in steps 214, 222, and 231), and if YES, an error signal and error code are output.
After displaying the error details on the display section 63 (step 205), the process returns to step 201. The error signal output at step 205 is supplied to step 109 of the counting routine in FIG. 6 as indicated by the arrow.

Further, if there is no mixing of different denominations, no discrepancy between the front and back sides, and no discrimination abnormality (NO), the process proceeds to the next step 206.

Note that when the first trigger signal (TRG) is output, steps 215, 222, and 232 have not been passed and no determination has been made, so the first step 204 is always NO and the process proceeds to step 206.

<Step 206> Double feed detection sensor 37+38 in step 203
Based on the detection data taken in from the banknote and the double comparison level which is the discrimination standard set in step 218 (described later), it is determined whether or not the banknote has been double-adsorbed, and if YES, an error signal is sent. and an error code, and the error details are displayed on the display section 6.
3 (step 207), the process returns to step 201.

The error signal output in step 207 is supplied to step 109 of the counting routine in FIG. 6 as indicated by the arrow.

If NO, that is, if it is determined that there is no double adsorption, the process proceeds to the next step 208.

Note that, as in step 204, when the trigger signal (TRG) is output for the first time, the banknote Sa for which double adsorption should be determined does not exist in the position shown in Figure 1, and the reference double comparison level has not been set. Therefore, this step 206 is always NO and the process proceeds to step 208.

<Step 208> Select the analog switch 79 shown in FIG.
By storing the output of the area sensor 34 in the RAM 65 via the amplifier 72 and the A/D converter 73, area data in the area E (data on the N line) is captured. Note that this area data is taken in based on the flow shown in FIG.

That is, when a capture signal is output (step 300), after setting Y to 0 and X to 0 (step 301), the process proceeds to the next step 302. and,
In this step 302, it is determined whether or not the output of the necessary N lines of data (line data) has been completed.If YES, a determination start signal is output (step 303), and the main Return to routine. If the answer is NO at step 302, the data of the specified N line is sent to step 312.
Steps 304 to 311 are looped until the data is output, and when the data is output, the process proceeds to step 303 as described above.

When the line-by-line acquisition of area data is completed in this manner, the process proceeds to the next step 209 shown in FIG.

<Step 209> Check whether the data acquired in step 208 is at a level that does not have a pattern (i.e.,
Whether it is a black pattern on the surface 1b of the first half holder 1)
If it is YES (no data), after outputting the end signal (step 210), step
Return to 201. The end signal output at step 210 is supplied to step 133 of the counting routine in FIG. 6 as indicated by the arrow.

Further, if the captured area data is of a level having a pattern (NO), the process advances to the next step 211.

<Step 211> Determine whether or not the setting mode is set to amount calculation mode, and if YES, determine which denomination of each banknote loaded in the holder. If the answer is NO, the process advances to step 212.

<Step 212> Determine whether or not the bill attracted by the suction shaft 5 is the first one. If YES, proceed to step 213; if NO, proceed to step 230.
Proceed to.

<Step 213> Based on the area data of the first bill imported in step 208, the standard of the current 3 denominations (L denominations) totaling 12 patterns (4 x L patterns) stored in the ROM 64 Comparing with the data (for one denomination, there are 4 patterns of front and back, forward and reverse),
Proceed to the next step 214.

<Step 214> As a result of comparing the area data of the first bill with the standard data of the 12 patterns, it is determined whether there is a matching pattern, and if NO,
It is determined that the banknote is an abnormal banknote that cannot be determined, and a flag indicating an abnormality in determination is set in a predetermined area of the storage unit (RAM 65) (step 215).
Return to 201.

If there is a matching pattern (YES), a flag indicating that the identified banknote is one of the three denominations is set in a predetermined area of the storage unit (RAM 65) (step 216). ), and after setting a flag indicating the front and back sides of the banknote (step
217), based on the determined denomination and front and back information.
After setting the double comparison level, which is a criterion for determining double adsorption, stored in the ROM 64 in the storage section (RAM 65) (step 218), the process proceeds to step 219.

As described above, in the amount calculation mode, the counting control circuit 45 automatically calculates the total amount of the flipped bills at any time based on the denomination code output in step 216, and also performs this calculation. The results can also be displayed at any time on the display section 63 as described above.

<Step 230> On the other hand, if it is determined in step 212 that the bill attracted by the suction shaft 5 is not the first bill, the area data of the bill taken in in step 208 and the area data stored in the ROM 64 are specified denomination (denomination set in step 216)
The process proceeds to the next step 231 after comparing only the reference data of four patterns of front and back, forward and reverse.

<Step 231> As a result of comparing the area data of the banknote with the reference data of the four patterns, it is determined whether there is a matching pattern, and if NO, this banknote is a banknote of a different denomination (strictly speaking, There may also be banknotes with abnormal identification)
, a flag indicating a different denomination is set in a predetermined area of the storage section (step 232), and the step
Return to 201.

Also, if there is a matched pattern (YES)
As described above, a flag indicating the front and back sides of the banknote is placed in a predetermined area of the storage unit (step 217).
Furthermore, in step 218, the amount of transmitted light of the banknote is set in a predetermined area of the storage section, and the process proceeds to the next step 219.

<Step 219> It is determined whether the front/back mode switch 54 is turned ON or not. If NO, proceed to step 201; if YES, proceed to the next step 220.

〈Step 220〉 Determine whether this banknote is the first one, and select NO.
If YES, proceed to step 222; if YES, proceed to the next step 221.

<Step 221> The front and back codes of the first banknote set in step 217 are stored in the storage unit as front and back reference data.
It is set in the RAM 64, and based on this front/back reference data, banknote front/back determination is performed (step
222).

<Step 222> The front and back codes set in step 217 are compared with the front and back reference data set in step 221 to determine whether or not the second and subsequent banknotes match the front and back of the first banknote. If they match (YES), the process returns to step 201. If there is a mismatch (NO), the process proceeds to the next step 223, where a flag indicating that the front and back sides do not match is set in a predetermined area of the storage section.
Go back to step 201 and repeat the steps above.
Repeat steps 201 to 232.

Note that the timing of the above-mentioned trigger signal (TRG), duplex data capture, etc. is described in the timing chart of FIG. If these trigger signals (TRG), the timing of importing double data, etc. correspond to the step numbers in FIG. 7, the discrimination trigger signal corresponds to step 201,
The double data acquisition timing corresponds to step 203, below, the error check timing corresponds to step 204, and the double check timing corresponds to step 203.
206, area data import timing corresponds to step 208, erasure check timing corresponds to step 209, discrimination processing timing corresponds to steps 211 to 214 and steps 230 and 231, and furthermore, denomination, front and back, The double comparison level and error set timing correspond to steps 216 to 218 and steps 215, 223, and 232, respectively.

In addition, in this determination processing flow, when determining the denomination of the second and subsequent coins when the mode is not in the amount calculation mode, that is, when both steps 211 and 212 are NO, only the different denomination code can be output as the error code. Immediately before step 232 of this discrimination processing flow, a comparison is made with the remaining eight patterns to determine whether or not there is a matching pattern, and if there is a matching pattern, it is left as is. Proceed to step 232 to set the different denomination code, and if there is no matching pattern, proceed to step 232.
It is also possible to proceed to 215 and set a discrimination error code.

The banknote counting machine configured as described above reads the front and back patterns of a banknote, determines its denomination, and outputs a denomination code (step 216), while outputting a determination error code when the denomination cannot be determined. (Steps 215, 207) and interrupts the bill flipping operation by the suction shaft 5 (Steps 109 and 112 to
114), during this interruption, the banknote determined to be an abnormal banknote is visually confirmed and its denomination is input (steps 161 to 166).

Then, when the denomination of this abnormal banknote is confirmed and input (steps 167 and 168), the suspended state in which flipping has been prevented is canceled (step 167 and 168).
170 to 172), automatically restarts the banknote flipping and denomination determination operation from the point of interruption (steps 101 to 172).
In addition, the denomination code (output in step 170) that was set after checking the denomination at the time of interruption,
During counting before and after the interruption, the total amount of banknotes loaded in the holder is calculated and displayed based on the automatically determined and set denomination code (output at step 216) (steps 145 and 147). I decided to do so.

Therefore, according to this banknote counting machine, even if the banknote discrimination process is interrupted due to the output of an error signal, it is possible to input the denomination information for the abnormal banknote at the time of interruption, and When inputting this denomination information, it is possible to automatically restart the banknote flipping and denomination determination operation from the point of interruption, making it impossible to determine the banknote denomination as with conventional counters. This eliminates the need for complicated operations such as redoing the denomination discrimination from the beginning each time, and the work of counting and discriminating banknotes can be carried out efficiently.

In addition, each time the banknote discrimination operation is interrupted, the denomination of the abnormal banknote is visually confirmed, and the denomination information for the abnormal banknote is input as appropriate, so that the banknote cannot be loaded into the holder. The total amount of banknotes can be calculated accurately.

In addition, when changing the program for discriminating Japanese banknotes to a program for discriminating US dollar banknotes, this is done by replacing the ROM 64 or the like.

Further, in the discrimination control circuit 46 described above, the line data is extracted along the X axis, but the line data is not limited to this, and may be extracted along the Y axis.

Furthermore, as a sensor for reading the surface pattern in the area E, in place of the area sensor 34, a plurality of one-dimensional image sensors are arranged at intervals with respect to the Y axis or the X axis shown in FIG. The detected data may be read out by specifying a column.

``Effects of the Invention'' As explained in detail above, according to the present invention, the front and back patterns of banknotes are read, the denomination is determined, and a denomination code is output, and when the denomination cannot be determined, a code beyond the recognition level is output. output, the operation of turning over the banknotes by the suction shaft is interrupted, and at the time of this interruption, the banknote determined to be an abnormal banknote is checked and its denomination can be inputted, and the denomination of the banknote with the abnormality determination is inputted. When input and confirmed, the interrupted state in which bill flipping was blocked is canceled and the bill flipping and denomination discrimination operation from the point of suspension is automatically resumed. The total amount of banknotes loaded into the holder is calculated based on the denomination code that is automatically determined and output and the set denomination code that is input to confirm the denomination at the time of interruption. It is possible to automatically restart the denomination discrimination operation for turning over banknotes, and to accurately calculate the total amount of banknotes loaded in a holder when denomination information cannot be inputted for banknotes with abnormal discrimination. This has the effect of making it possible.
