Description

[Detailed description of the invention]

The present invention relates to a different type of bill discriminating device for a paper sheet counter. This applicant previously proposed the invention described in the specification of Japanese Patent Application No. 51-103284 (hereinafter referred to as the prior invention). The paper sheet counting machine of this prior invention, for example, the banknote counting machine, automatically automatically removes banknotes of different sizes and denominations (different types of banknotes) during counting when the banknote bundle to be counted contains banknotes of different denominations (different types of banknotes). Different types of tickets can be distinguished by photoelectric detection means. Therefore, it is possible to reliably distinguish between different types of notes in a banknote bundle, which was impossible to distinguish using conventional banknote counting machines, and it is therefore possible to perform desired actions on different types of notes, such as invalidating the identified different types of notes. It has various features such as being able to obtain accurate counting results for normal tickets. By the way, the size of the banknotes currently in circulation in Japan varies depending on the denomination, and the width and height of the banknotes decrease in the order of 10,000 yen, 5,000 yen, 1,000 yen, and 500 yen. It's summery. For this reason, for example, if a bundle of large banknotes, 10,000 yen notes, contains a different type of banknote, a 500 yen note, which is a small banknote,
Due to friction between the bills, the lower edge of the 500 yen bill may not match the lower edge of the 1 yen bill and may end up being set in the holder of the counter in a floating state.
However, in the case of the prior invention, for a banknote bundle in which the lower ends of each banknote in the banknote bundle are all aligned and coincident, it is possible to reliably discriminate between different types of banknotes mixed in the banknote bundle. As described above, there remains a problem in that it is not possible to reliably distinguish between different kinds of bills in a bundle of bills whose lower ends do not match. This invention was made in consideration of the above-mentioned circumstances, and its purpose is to transmit the ticket type discrimination signal corresponding to the first sheet turned over during counting to the second and subsequent sheets. By using a simple configuration as a reference signal for discriminating different types of notes in paper sheets, the number of different types of notes in a bundle of paper sheets can be accurately and easily grasped.
It is an object of the present invention to provide a different type bill discriminating device for a paper sheet counting machine, which allows desired treatment to be performed on the discriminated different types of bills. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a different type of bill discriminating device for a bill counting machine will be described below with reference to the drawings. FIG. 1 is a top view showing a schematic configuration of the main parts of a banknote counting machine, and FIG. 2 is a schematic layout diagram of an optical system. Multiple pieces (in this example, 5 pieces) are placed concentrically on the top of the banknote counting machine.
On one side of the rotary cylinder 2, which rotatably supports the suction head 1, there is a banknote bundle holder 3 whose rear end is rotatably supported, and a banknote bundle holder 3, which is close to the approximate center of the inner surface of this holder 3. A banknote bundle holding rod 4 is provided. Further, above the free end of the holder 3, an arc-shaped bill stopper 5 is vertically provided. On the other hand, a conventionally known non-contact switch 7' is installed close to the side wall surface of the rotating cylinder 2, and
The same number of pieces of magnetic material 8 as the suction head 1, that is, in this example, five pieces of magnetic material, such as pieces of iron, are attached to the side circumferential wall surface of the rotary cylinder 2 at equal intervals.
In addition, as will be described later, various timing signals t ₁ , t ₂ , t ₃ (Figure 10) are used to obtain the timing for detecting the lower edge of a banknote and the timing for discriminating and detecting different types of bills.
A non-contact switch 7 is provided to obtain the following. Here, to explain the operation of the banknote counting machine configured as above, first, in a steady state in which banknote counting operation is not performed, the banknote bundle holder 3 is
They are each stably held at the positions indicated by the imaginary lines in FIG. 1, which are farthest from each other. On the other hand, when performing a counting operation, first the banknote bundle 6 to be counted is placed on the holder 3 in a predetermined state, and when this holder 3 is rotated clockwise by a predetermined angle, the banknote bundle 6 is held by the presser rod. 4 and the first
It is set at the position closest to the rotary cylinder 2 as shown by the solid line in the figure. Next, in this state, the frontmost banknote is attracted and a vacuum switch (not shown) is turned on (see Fig. 10k), causing the rotary cylinder to
is rotated in a predetermined direction (counterclockwise in this example) at a predetermined speed. At this time, in synchronization with the rotation of the rotary cylinder 2, each suction head 1 is moved to a position closest to the inner side surface of the banknote bundle 6, which is located above the presser rod 4.
The suction surfaces of the banknotes are opposed to each other, and the innermost banknote is turned over and adsorbed from the banknote bundle 6, and then the suction force is released and the turned-over banknote is conveyed further backward. It is rotated at a predetermined speed in the opposite direction to the rotating cylinder 2, that is, in this example, clockwise. In this way, each banknote in the banknote bundle 6, which is held between the banknote bundle holder 3 and the presser rod 4 in a predetermined state, is sequentially moved one by one by the suction head 1, starting from the one located at the innermost side. After being turned over, the banknotes are further conveyed to the rear, and a non-contact switch 7' is activated each time each banknote is turned over.
is closed once. Therefore, one counting pulse is generated each time the non-contact switch 7' is closed, as shown in FIG. 10j. It is well known to those skilled in the art that by counting these counting pulses, the number of banknotes in the banknote bundle 6 can be easily counted. Furthermore, a timing pulse is generated each time the non-contact switch 7 is closed, as shown in FIG. 10a. By the way, the banknotes currently used in our country are
There are four types of banknotes: 10,000 yen notes, 5,000 yen notes, 1,000 yen notes, and 500 yen notes, and these four types of banknotes increase in height in this order as shown in Figures 3 and 4. It's getting lower. Further, as mentioned above, when the banknote bundle 6 to be counted is placed on the banknote bundle holder 3 of the banknote counting machine, normally only banknotes of the same type are loaded in a state in which they are aligned on the loading surface, that is, the bottom surface. . By the way, if a different type of note is mixed in the banknote bundle 6, and the lower edge of the different type of note does not match the lower edge of other banknotes, and it is not placed in a normal position in a jammed and floating state, As shown in Figure 5, the irregularity is greatest at the top of the 10,000 yen note, which is the largest banknote, and at the top of the 10,000 yen note, the 5,000 yen note, the 1,000 yen note, and
This is a case where the upper ends of each 500 yen note match. In this invention, the different types of bills mixed in the banknote bundle in such an irregular state are irradiated with light from a light source on the upper and lower ends of the banknote bundle 6 placed on the banknote bundle holder 3, Further, this light is detected by a photoelectric conversion means which is configured to receive the light by an upper end photoelectric conversion element or a lower end photoelectric conversion element provided for each ticket type, and a signal obtained by this photoelectric conversion means is sent to a discriminating means. This system is designed to perform type discrimination and different type of ticket discrimination. Further, in this invention, the number of tickets of each ticket type is determined by using the ticket type discrimination result.
I am trying to calculate the amount etc. For this reason, in this embodiment, each banknote in the banknote bundle 6 held in the banknote bundle holder 3 is sequentially turned over one by one by the action of each suction head 1 on the rotary tube 2 while being conveyed. For example, as shown in FIGS. 1 and 2, the projection light 12 from the lamp 10 is first applied to the lower end of each banknote through the projection lens 11 by a synchronization signal with the instantaneous rotation cylinder 2 which is attracted to the suction head 1. The reflected light 13 obtained as a result is received by the photoelectric conversion elements 15, 15A to 15D provided for each denomination in the light receiver 15 through the condensing lens 14, and thereby the banknotes of each banknote are The position of the lower edge is detected, and after a slight delay, the upper edge of each banknote is irradiated with the projection light 19 from the lamp 17 through the projection lens 18, and the transmitted light 2 obtained as a result of this is
0 to the photoelectric conversion elements 22, 22A to 22 provided for each denomination in the light receiver 22 through the condensing lens 21.
The photoelectric conversion means is configured to receive light from D as shown in FIG. 3, thereby detecting the position of the upper end of each banknote. Note that the shaded areas 23A to 23D in FIG. 4 are the photoelectric conversion elements 22A to 2.
2A and 2B illustrate examples of monitoring areas where light is received by 2D. Furthermore, Fig. 5 shows the situation when the irregularity of the lower edge is at its maximum when bills of other denominations are mixed as different types of bills in a banknote bundle of large banknotes of 10,000 yen as described above. This figure shows the arrangement of photoelectric conversion elements 15A to 15D for each denomination, which detect the lower end position of each denomination of banknote, corresponding to this state. Note that in FIG. 5, the shaded area 24
A to 24D are photoelectric conversion elements 15A to 1, respectively.
5D monitoring area is shown. The light receiving element indicated by symbol A in FIG. It detects that the lamp is burnt out and issues an alarm.
Any control using a light emitting source such as a lamp naturally belongs to well-known and commonly used techniques. Also, what is shown in the symbol B in the figure is a slit, and the lamps 10 and 1 are slits.
The light irradiated from 7 is passed through a slit to improve its directivity, and this also belongs to the well-known and commonly used technology. Next, the circuit configuration of this embodiment will be explained with reference to FIGS. 6 to 10. The photoelectric conversion elements 15A to 15D, 22A to 2
2D, and amplifiers 28A to 28D, 32A to be described later.
32D and the comparison circuits 29A to 29D constitute the detection means in the claims. In addition, a latch circuit 30, a lower end position determination circuit 31, analog switches 33A to 33D, and a peak point holding circuit 3, which will be described later, are also provided.
4A to 34D, level conversion switch 35, comparison circuits 36A to 36D, and bill type discrimination circuit 37 constitute bill type discrimination means in the claims. Each output signal from the photoelectric conversion elements 15A to 15D is appropriately amplified via amplifiers 28A to 28D corresponding to the respective phases, and then sent to comparison circuits 29A to 29.
D and is compared with a predetermined reference level in each comparison circuit 29A to 29D. Each comparison result signal from these comparison circuits 29A to 29D is applied to a latch circuit 30.
0, a timing pulse _t3 , which will be described later, is added as a read drive signal. Therefore, the latch circuit 30
The operation of reading and storing a new comparison result signal is repeated every time the timing pulse _t3 is applied. Furthermore, the signal stored in this latch circuit 30 is applied as 4-bit data to a lower end position determination circuit 31, and by configuring this circuit 31 in the same manner as the bill type determination circuit 37 shown in FIG. 8, which will be described later, for example, A detection block correction signal DB (see FIG. 10f) based on the detection of the lower end of the banknote is outputted from one of the four output terminals of the circuit 31. In this case, for normal banknotes, only the output from any one of the comparison circuits 29A to 29D is output as a "1" signal, but in rare cases, the detection location of the banknote is likely to be reflected by a foreign object, etc. In this case, there is a possibility that a “1” signal is output from two or more comparison circuits 29A to 29D.
-29D, only the output ("1" signal) of one normally operating comparison circuit is selected. Then, the comparison circuit 29A operates normally and becomes “1”.
When the signal is output, the detection block correction signal DB is output only from the output terminal A of the lower end position determination circuit 31, and is applied to the control input terminal SC of the analog switch 33A. Similarly, the comparison circuit 29B,
When either 29C or 29D operates normally and outputs a "1" signal, the detection block correction signal DB is output from the output terminals B, C, and D of the lower end position determination circuit 31, respectively. Corresponding analog switches 33B, 33C, 33D
is applied to the control input terminal SC. On the other hand, each output signal from the photoelectric conversion elements 22A to 22D is transmitted to a corresponding amplifier 32A to 32D.
Analog switches 33A to 33A, any one of which is activated by the detection block correction signal DB via
The signals are applied to input terminals I _A to _ID of 33D, respectively, as shown. And analog switches 33A to 33
The output terminals D, C, B, and A of D are configured to correspond to a 10,000 yen note, a 5,000 yen note, a 1,000 yen note, and a 500 yen note, respectively. That is, when the lower end of the banknote is placed in the normal position, the photoelectric conversion element 15D
is activated, and the detection block correction signal DB activates only the analog switch 33D. In this case, for example, when there is a light receiving input to the photoelectric conversion element 22A, an analog signal is outputted only from the output terminal D of the analog switch 33D and applied to the input terminal of a peak point holding circuit 34D, which will be described later. Further, for example, when there is a light reception input to the photoelectric conversion element 22C, an analog signal is output only from the output terminal B of the analog switch 33D, and is applied to the input terminal of the peak point holding circuit 34B. However, if the lower end of the banknote is not placed in the normal position and, for example, the photoelectric conversion element 15B is activated, only the analog switch 33B is activated; however, in this case, the photoelectric conversion element 2
When there is light reception input to 2A, an analog signal is output from output terminal B of analog switch 33B, but on the other hand, when there is light reception input to photoelectric conversion element 22B, an analog signal is output from output terminal A of analog switch 33B. be. In this way, the photoelectric conversion elements 22A to 22D for detecting the upper end of the banknote and the photoelectric conversion element 15 for detecting the lower end of the banknote
Combination with A to 15D and analog switch 3
By the action of 3A to 33D, even if the lower end of a different type of bill is mixed into the banknote bundle 6 in a manner that is not aligned with the lower end of other banknotes, the peak point holding circuits 34A to 34D retain the denomination of the different type of note. An analog signal can be output only to one corresponding peak point holding circuit. Table 1 shows the output status of detection signals from the upper end detection photoelectric conversion elements 22A to 22D and the lower end detection photoelectric conversion elements 15A to 15D and the corresponding denominations. In Table 1, it can be seen that, for example, when detection signals are output from each of the photoelectric conversion elements 15C and 22B, an analog signal is output only to the input terminal of the peak point holding circuit 34B corresponding to the thousand yen bill. The peak point holding circuits 34A to 34D correspond to 500 yen notes, 1000 yen notes, 5000 yen notes, and 10,000 yen notes, respectively.

[Table] 500 yen coupon for analog switches 33A to 33D,
Output signals from output terminals A, B, C, and D corresponding to 1,000 yen notes, 5,000 yen notes, and 10,000 yen notes, respectively, are transmitted to peak point holding circuits 34A and 3 for the corresponding denominations, respectively.
4B, 34C, and 34D and are stored therein, but the timing signal from the timing signal generation circuit 25 is input to the peak point holding circuits 34A to 34D.
t ₃ is added as a control signal. Therefore, the contents of each of the peak point holding circuits 34A to 34D are updated every time the timing signal _t3 is output. Further, the output of each peak point holding circuit 34A-34D is sent to the first comparison input terminal of the corresponding comparison circuit 36A-36D. A predetermined reference level signal output from the level conversion switch 35 is input to the second comparison input terminals of the comparison circuits 36A to 36D. Therefore, each comparison circuit 36A to 36
In D, peak point holding circuits 34A to 34D
The input signal from the reference level signal is compared with the reference level signal. This reference level signal is usually set for general distribution notes and new notes, but when a heavily soiled banknote bundle is discriminated and counted, the output level of the top edge detection photoelectric conversion elements 22A to 22D is reduced. Therefore, the peak point holding circuits 34A to 34
Since the level of the peak point stored in D also decreases, there is a risk that the comparison circuits 36A to 36D may malfunction. Therefore, in such a case, the reference level is lowered in advance by the level conversion switch 35, thereby making it possible to carry out the comparison and discrimination operation. Each comparison result signal from the comparison circuits 36A to 36D is applied to a bill type discrimination circuit 37. The ticket type discrimination circuit 37 has a circuit configuration as shown in FIG.
KD or abnormal feed signal KZ is output. That is, the bill bundle 6 loaded in the bill bundle holder 3 is turned over by the suction head 1 and projected light 1 from the lamps 10 and 17.
Assuming that the bill is a 10,000 yen note that is irradiated by 2, 19, the largest amount of light reception input is obtained to the photoelectric conversion elements 15D to 22A, and thereby, the light is transmitted through the output terminal D of the analog switch 33D. Only the peak point holding circuit 34D operates to store and hold the peak point, thereby setting the comparator circuit 36D to operate. At this time, the remaining photoelectric conversion elements 22B to 22
D, 15A to 15C also receive some light reception input, but in the case of a regular 10,000 yen note, the comparison circuits 36A to 36C are set to operate at the peak point level held by the peak point holding circuits 34A to 34C. However, the comparator circuits 36A to 36C are set to operate only in the case of a 10,000 yen note that is partially worn out. However, the ticket type discrimination circuit 37
Since the is configured as shown in FIG. 8, the output signals of the comparison circuits 36A to 36D are given priority, and as shown in Table 2, in the case of a 10,000 yen note, the output signals are output from the output terminal 37D. A “1” level ticket type discrimination signal (10,000 yen bill discrimination signal) KD is output only from

[Table] Projection lights 12 and 19 from the other lamps 10 and 17
If the banknote being irradiated by is a 5,000 yen note, the combination with the largest amount of light receiving input is photoelectric conversion elements 15D to 22B or 15C to 2.
2A, the peak point is stored and held in the peak point holding circuit 34C via the output terminal C of either the analog switch 33D or 33C, and only the comparison circuit 36C is set to operate. At this time, there is no output from the combination of photoelectric conversion elements 15D to 22A, and the comparison circuit 36D
is never set to work. In addition, some light reception input can be obtained to the remaining photoelectric conversion elements 15A, 15B, 22C, and 22D, but in the case of a regular 5,000 yen note, the level of the peak point held by the peak point holding circuits 34A, 34B Now, the comparison circuit 36
A and 36B are not set to operate, but only in the case of a partially worn 5,000 yen note, the comparison circuit 36
A and 36B may be set to operate, but the output terminal 3 is determined by the ticket type discrimination circuit 37 as shown in Table 2.
A "1" level bill type discrimination signal (5,000 yen bill discrimination signal) KC is output only from 7C. In addition, when the banknote being irradiated is a thousand yen note, the combination with the largest amount of received light input is photoelectric conversion elements 15D to 22C, 15C to 22B, 15D to
22A, the peak point is stored and held in the peak point holding circuit 34B via the output terminal B of any one of the analog switches 33D, 33C, and 33B, and the peak point is stored and held in the peak point holding circuit 34B.
Set the operation of only 6B. At this time, photoelectric conversion elements 15D to 22B, 15C to 22A, 15D to 2
There is no possibility of a combined output of 2A, and the comparator circuits 36C and 36D are never set to operate.
In addition, the remaining photoelectric conversion elements 15A, 15B, 22
Although some light reception input can be obtained at D, in the case of a steady 1,000 yen note, the comparison circuit 36A is not set to operate at the peak point level held by the peak point holding circuit 34A, but only partially. The comparison circuit 36A may be set to operate only in the case of a 1,000 yen note that has been worn out, but the second
As shown in the table, a "1" level ticket type discrimination signal (thousand yen bill discrimination signal) KB is output only from the output terminal 37B. Furthermore, if the banknote being irradiated is a 500 yen note,
The combination with the largest amount of light receiving input is photoelectric conversion elements 15D to 22D, 15C to 22C, 15B.
~22B, 15A~22A, which causes the analog switch 33D,
The peak point is stored and held in the peak point holding circuit 34A via the output terminal A of any one of 33C, 33B, and 33A, and only the comparison circuit 36A is set to operate. At this time, there cannot be an output from a combination of other photoelectric conversion elements, and the comparison circuits 36B, 36
C and 36D are never set to operate. Therefore, as shown in Table 2, the output terminal 3 of the ticket type discrimination circuit 37
A “1” level ticket type discrimination signal (500 yen bill discrimination signal) KA is output only from 7A. On the other hand, the projected light 12,1 from the lamps 10,17
If two or more of the banknotes irradiated by 9 are turned over at the same time due to a malfunction of the suction head 1 or a defect such as damage to the banknotes, regardless of the type of banknote, or if the banknotes are abnormally stained or otherwise severely stained. , each photoelectric conversion element 15A to 15D,
The amount of light received by 22A to 22D is significantly reduced compared to the case of the above-mentioned stationary ticket, or there is virtually no light reception input, and the level of the peak point held in each peak point holding circuit 34A to 34D decreases. In this case, the comparison circuits 36A to 36D are held in an inoperative state without being set to operate. As a result, there is no output from the output terminals 37A to 37D corresponding to the bill type of the bill type discriminating circuit 37, and as shown in Table 2, the abnormal feed signal KZ of the "1" level is output only from the output terminal 37Z corresponding to the abnormal feed. Output. The lower limit value of the banknote is detected each time a banknote in the banknote bundle 6 loaded on the banknote holder 3 is turned over by the action of the suction head 1 as the rotary cylinder 2 rotates, or a different type of banknote is detected. In order to obtain the timing to perform the detection, the synchronous pulse (Fig. 10a) generated by the non-contact switch 7 is
) is input to the timing signal generation circuit 25. And the timing signal generation circuit 25
From there, three types of timing pulses t ₁ , t ₂ , and t ₃ as shown in FIG. 10b, c, and d are generated. These timing signals t ₁ to _{t 3} are input to a timing signal control circuit 40 . The timing signal control circuit 40 generates a timing pulse t ₁ from the timing signal generation circuit 25 in order to create a timing to set a normal bill signal for detecting a different type of bill, a timing to enable detection of a different type of bill, and detection of abnormal feeding. , t ₂ , and t ₃ . Furthermore, this circuit 40 is a circuit that is effective from the timing pulse generated after the start of the counting operation, and is a circuit that prevents the operation of detecting different types of bills after the completion of the counting operation.
A counting completion signal CO, which is output when ST and a vacuum switch (not shown) is turned off, is input to the timing signal control circuit 40. Next, the genuine bill signal control circuit 38 will be explained. This circuit 38 includes the timing signal control circuit 4.
In other words, in this embodiment, when the timing pulse t ₂ (the second timing pulse t ₂ after the start) occurs after the first sheet is turned over and identified, the ticket type is determined by the timing controlled by 0. Any one of the bill type discrimination signals KA to KD output from the discrimination circuit 37 for the first bill is stored as a regular bill signal CRD for a different type of bill, and the stored first bill type discrimination signal is (correct winding signal CRD) is sent to a different type of bill discriminating circuit 39, which will be described later, and this circuit 39 generates a bill type discriminating signal for the second and subsequent bills.
It is configured to perform a comparison operation with KA to KD to discriminate between different types of tickets. For this reason, the valid bill signal control circuit 38 includes bill type discrimination signals KA to KD,
KZ and timing pulse t' ₂ from timing signal control circuit 40 are input. In addition, if there are different types of notes on both sides of the banknote bundle, the operator shall remove these different types of notes before starting the counting operation.
Furthermore, if the first banknote is abnormally fed, this is treated as an error occurrence. The different type of note discrimination circuit 39 receives the normal note signal CRD.
In addition to the above, ticket type discrimination signals KA to KD, KZ, and timing pulses P ₁ , P ₂ , and P ₃ output from the timing signal control circuit 40 are input. As a result, this circuit 39 inputs and stores the genuine bill signal CRD, and then inputs the second and subsequent bill type discrimination signals KA~KD, KZ, and inputs these signals KA~KD.
The comparison operation between the counter and the valid bill signal CRD is performed every time the third and subsequent timing pulses _t1 occur after the start of the counting operation. If a discrepancy is detected during execution of this comparison operation, a dissimilar bill detection signal DIF is output from the output terminal 43 to light a lamp, or to drive another appropriate alarm device to stop the count. This is to notify that different types of bills are mixed in the banknote bundle 6. Further, this circuit 39 inputs the abnormal feeding signal KZ and starts the abnormal feeding control operation from the time when the bill type discrimination operation is executed for the first bill, and when abnormal feeding occurs, abnormal feeding is detected from the output terminal 42. Signal ET
The alarm is issued in the same manner as described above. In order to enable the above-mentioned operation, the normal bill signal control circuit 38, the dissimilar bill discriminating circuit 39, and the timing signal control circuit 40 are each configured as shown in FIG. 9 to perform the dissimilar bill detection operation. Since what can be realized can be easily understood by those skilled in the art, detailed explanation thereof will be omitted. In addition, the above-mentioned abnormal feed detection signal ET and dissimilar ticket detection signal DIF are manually cleared signals.
It is configured to be reset when CLR occurs or when a start signal ST is generated at the start of the next counting operation. Next, the arithmetic circuit 26 and display circuit 2 input the ticket type discrimination signals KA to KD and the abnormal feed signal KZ to calculate, display, and print the number of tickets, amount, etc. of each ticket type.
7. The configuration of the printing circuit 41 will be explained with reference to FIG. Each of the ticket type discrimination signals KA to KD is gate-controlled by a timing pulse _t1 , and a gate circuit 9 includes AND gates 90A to 90D.
In addition to being input to the corresponding counting circuits 60A to 60D through 0 and counted by denomination,
It is also input to the counting circuit 33T via OR1, and the total number of sheets is also counted. Each count value of the counting circuits 60A to 60D is sent to the number display section 62C in the display circuit 27 and displayed for each denomination, and is also sent to amount conversion circuits 61A to 61D provided for each denomination. converted into an amount. Further, the count value of the counting circuit 33T is sent to the total number display section 62 and displayed. Further, each amount data output from the amount conversion circuits 61A to 61D is sent to the amount display section 62B and displayed by denomination, and is also sent to the amount adding circuit 61.
It is sent to T and the total amount is calculated. The total amount data output from this circuit 61T is sent to the total amount display section 27 and displayed. Furthermore, each of the counted values, the total number of sheets, each amount data, and the total amount data are all sent to the printer control unit 63 in the printing circuit 41, and are automatically output when the discrimination counting operation is completed, or are output manually by button operation. The printer 64 prints out the print command signal PC when the print command signal PC is output. After the discrimination count, number of sheets, and amount are displayed in this way, the manual reset signal MR output by operating the manual reset button etc. is sent to each counting circuit 60A to 60 via the OR gate OR2.
D, 60T, and is configured to reset them, so that the contents of the number of sheets and amount displayed on each of the display sections 62A to 62D of the display circuit 27 are reset to zero. Also, for each count, an automatic reset signal is sent, for example, when the holder 3 closes.
It is also possible to output AR and reset via gate 65 and OR gate OR2. Further, when each data (amount, number of bills) of the banknote bundle 6 that is sequentially counted is added (accumulated), the gate 65 is closed by the addition mode signal SM to prevent resetting by the automatic reset signal AR. . Further, the abnormal sending signal KZ is sent to the flip-flop via an AND gate 90z in the gate circuit 90.
The signal is sent to the set input terminal S of FF2 to set the flip-flop FF2, and the set output signal is sent to the alarm drive circuit 66 so that an alarm sound can be generated or an alarm can be displayed. The output signal X of the reset signal (MR or AR) is input to the reset input terminal R of the flip-flop FF2, thereby resetting the flip-flop FF2 and stopping the alarm sound and alarm display. be. The set output signal of the flip-flop FF2 is sent to the counting circuit 67, and the timing pulse t3 is input to the reset input terminal R of the flip-flop FF2 via the OR gate OR3, and the timing pulse _t3 is inputted to the reset input terminal R of the flip-flop FF2. If the count value of the counting circuit 67 is configured to be sent to the display 68, it is also possible to count and display the number of occurrences of the abnormal sending signal KZ. Further, by providing a selection switch 69 in the display circuit 27, it is also possible to select only a desired display section from among the display sections 62A to 62D for display operation. Next, a second embodiment of the present invention will be described with reference to FIGS. 11 and 12. In this second embodiment, by providing a bill type designation input device 44, a genuine bill signal CRD is manually inputted to detect a different type of bill. That is, in the first embodiment (FIG. 6), the bill type of the first bill after the start of the counting operation was determined, and the resulting signal was stored as the correct bill signal CRD. In Fig. 1), the operator sets a valid note in advance, and attempts to detect a different type of note based on whether the set valid note signals CRDA to CRDD match or do not match the type of banknote to be counted. . Note that this second
In the embodiment, the same components as in the first embodiment are given the same numbers. The ticket type designation input device 70 is provided with an input device corresponding to each metal, and the input signal is sent to the control circuit 7.
1. If the control circuit 71 is configured as shown in FIG. 8, for example, only one of the valid bill signals CRDA to CRDD will be output, and if there is no input signal from the input device 71, a no-setting signal will be output.
CRDZ is output. Further, another configuration may be added so that an alarm occurs when two or more inputs are received at the same time. Therefore, the set genuine bill signal from the control circuit 71
CRDA to CRDD and the no-setting signal CRDZ are applied to a valid bill signal control circuit 72, which has a different configuration from the first embodiment. That is, the set genuine note signal CRDA~CRDD
If there is an input, only the set valid note signal is regarded as valid and applied to the different type of note discriminating circuit 39 (true note signals 72A to 72D), and the lamps of the lamp group 74 corresponding to each designated denomination are turned on. Configure it as follows. In this case, it is necessary to perform dissimilar ticket detection operation from the first ticket for setting input.
By making the timing signal control circuit 73 have a different configuration from that of the first embodiment and further inputting the no-setting signal 72Z, different types of tickets can be detected from the first sheet based on the "0" level of the signal 72Z (with setting input). The signal 72Z is configured to start “1”.
The timing signal control circuit 47 is configured to perform the same operation as the configuration shown in FIG. 6 depending on the level (no setting input). In addition, no setting signal 72Z
By lighting the lamp 74- _L0 at the "1" level, it is possible to know that the mode is in which normal bills are automatically stored and foreign bills are detected. At this time, the lamp 74-L ₀ ,
The lamp 74 is activated by the output of the genuine bill signals 72A to 72D.
-One lamp among L ₁ to L ₄ lights up. In other words, when lamp 74-L ₀ is off (when there is a setting input), one of the other lamps is always turned on.
Only one lamp is lit. It should be noted that those skilled in the art will easily understand that this can be realized by configuring and connecting as shown in FIG. 12, for example, so that the above-mentioned timing can be switched depending on the presence or absence of the ticket type setting input. Therefore, detailed explanation thereof will be omitted. By the way, as a method for setting a reference note type that serves as a reference for detecting different types of notes, there is a method in which the note type of the first bill to be turned is determined and automatically set as the reference note type, and a note type specification input device is provided. The two methods of manually pre-setting the input settings have been shown, but there is also an invention previously described in the specification of Japanese Patent Application No. 77165/1983 by the present applicant, that is, the method of setting input on the holder. It is also possible to use a bill type discrimination method for determining the bill type by detecting the upper end position of a placed banknote bundle to set the reference bill type. That is, when a bundle of banknotes is placed on the holder, the detection signal from the banknote type discriminator installed on the holder is automatically stored as the standard banknote type, and the roll type is sequentially determined from the first banknote type. The purpose is to perform discrimination and detect different types of bills. In this case, in the device, the holder must also be equipped with a detector, and regarding the timing of setting the ticket type, it is necessary to determine whether the standard ticket type is determined immediately before counting or at the start of counting. The difference is that they are all the same in that the standard ticket type is automatically set and different ticket types are detected. Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, the lower end detection photoelectric conversion elements 15A to 15A in the first and second embodiments are used.
15D and upper end detection photoelectric conversion element 22A~
22D is removed, and in its place, lower end detection photoelectric conversion elements 15-1 to 15-8 (shown by dotted lines in FIG. 5) and upper end detection photoelectric conversion elements 22-1 to 22- are used.
8 (indicated by dotted lines in FIG. 3). That is, in this third embodiment, the photoelectric conversion elements for detecting the lower end and upper end positions are arranged in 8 stages (element 1
5-1 to 15-8 and 22-1 to 22-8), and photoelectric conversion elements 15-1 to 15-1 for detecting the lower end position.
The output of 15-8 is applied to comparator circuits 29-1 to 29-8 via amplifiers 28-1 to 28-8, and further inputted to encoder 80 in order to determine the lowest position of the banknote. In the encoder 80, the lower end position signal is converted into 4 bits, and the latch circuit 30
The signal at the output terminal _Q1 is input to analog switches 83A and 83B for pre-stage correction. That is, the upper photoelectric conversion elements 22-1 to 22-8, which are made effective by lower end position detection, are limited to combinations other than those indicated by the x marks in Table 3 in the pre-stage correction. Combinations marked with △ are valid, but there is no corresponding combination for the ticket type. and analog switch 8
The outputs after the correction by 3A and 83B are input to amplifiers 32A to 32D, amplified, and sent to analog switches 33A to 33D, as in the case in FIG.
applied to

[Table] By the way, the output latched to 4 bits by the latch circuit 30 is input to the decoder 81 and one of the 4 bits is input to the decoder 81.
It is configured to output a subsequent correction signal for selecting one of the analog switches 33A to 33D from two output terminals via an OR gate group 82. The subsequent configuration is similar to that of the first or second embodiment described above. By increasing the detection and resolution capability in this way, it is possible to more stably distinguish the type of bill, and therefore, the detection of different types of bills is also stabilized. As explained above, according to the present invention, there is provided a timing signal generating means for generating a timing signal for obtaining a timing for detecting paper sheets or a timing for discriminating between different types of bills, and a timing signal generating means for generating a timing signal for obtaining a timing for detecting paper sheets or a timing for discriminating between different types of bills, and a timing signal generating means for generating a timing signal during a turning operation by a suction head. a detection means for optically detecting a paper sheet based on a timing signal for obtaining a timing for detecting the paper sheet outputted from the means; a bill type discriminating means for outputting a bill type discriminating signal corresponding to the bill type; a storage means for storing a bill type discriminating signal of the first sheet turned over by the suction head as a reference signal; and a timing signal generating means. Based on a timing signal for determining the timing for discriminating different types of bills outputted from the means, the reference signal stored in the storage means and the bill type discrimination signal for the second and subsequent paper sheets turned over by the suction head are determined. If the comparison results do not match, a different type of note detection signal is output to notify that a different type of note is mixed in the bundle of paper sheets, and the note type discriminating means detects the first note turned over by the suction head. From the time when the bill type discrimination operation for the paper sheet is started and the bill type discrimination signal is output, it is determined whether or not there is an abnormality in the bill type discrimination operation based on the detection result of the detection means, and if an abnormality occurs, an alarm is issued. Since the configuration is equipped with a different type of ticket discriminating means to perform this, the following effects can be achieved. Instead of changing the paper sheet used as the standard for different types of bills in the counting operation, it is not necessary to change the paper sheet used as the standard for different types of bills for each sheet during the counting operation. By using a simple configuration as a criterion for discriminating different types of bills, it is possible to accurately grasp the number of different types of bills mixed in a bundle of paper sheets. As a result of the above, there is no need to perform the complicated operation of separately setting paper sheets as a standard for discriminating different types of bills, making it possible to easily and reliably detect mixed types of bills, thereby increasing paper sheet processing efficiency. improvement can be achieved. In addition, since the first sheet of paper that is turned over is checked to see if there is an abnormality in the ticket type discrimination operation and an alarm is issued if there is an abnormality, it becomes impossible to determine the ticket type of the first sheet of paper. This prevents the problem of not being able to set the standard paper sheet in the event of a problem.
This is suitable for further improving the reliability of the device.
