[Detailed description of the invention]

"Industrial Application Field" The present invention relates to a banknote counting machine having a denomination discrimination device. "Conventional technology" Banknote counting machines that have been put into practical use, for example,
In the counting machine described in Japanese Patent Application Laid-open No. 48-80079, each banknote in a banknote bundle loaded in a banknote bundle holder is sequentially sucked and turned over one by one by a suction head rotatably supported on a rotary tube. was configured to do so. "Problems to be Solved by the Invention" By the way, this type of banknote counting machine does not have a built-in device for discriminating different types of banknotes, and each banknote in the banknote bundle loaded in the banknote holder is It was configured to count all bills, regardless of whether they included banknotes or not. Therefore, in accordance with Japanese Patent Application No. 51-103284 (Japanese Patent Publication No. 59-38634), this application proposes a banknote counting machine having a different type of banknote discrimination device that outputs an alarm when a different type of banknote is detected. did. However, this banknote counting machine focused on detecting different types of banknotes, so when counting and checking the number of banknotes in a banknote bundle or calculating the amount of banknotes in a banknote bundle, it is necessary to read the banknotes by hand once. There was the disadvantage and inconvenience of having to check the contents of the banknote bundle, that is, the denomination. This invention has been made based on these circumstances, and its objectives are as follows. By developing a denomination discrimination device that can distinguish the denomination of each banknote that is turned over, manual reading as described above can be performed, for example, even when different types of banknotes are mixed in a banknote bundle. To provide a new banknote counting machine capable of easily detecting and checking different types of banknotes while rapidly and reliably counting the number of banknotes. To provide a banknote counting machine with high added value, which can be configured to automatically calculate the amount of a bundle of banknotes by performing denomination discrimination. "Means for Solving the Problems" In order to solve the above-mentioned problems, the present invention provides a suction head that is rotatably supported on a rotary tube to collect each banknote in a banknote bundle loaded in a banknote bundle holder one by one. In a banknote counting machine configured to count banknotes while sequentially suctioning them and turning them over, a plurality of photoelectrons each having a different monitoring area receive light obtained by irradiating light from a light source onto the banknotes that are being turned over by the suction head. a conversion element, a bill type discrimination circuit that discriminates the denomination of a flipped bill based on the output from these photoelectric conversion elements and outputs a denomination discrimination signal; The present invention is characterized by comprising a timing signal generation circuit that outputs a timing pulse to the bill type discriminating circuit to operate the circuit. Further, in a banknote counting machine configured to count each banknote in a banknote bundle loaded in a banknote bundle holder by sequentially suctioning each banknote one by one by a suction head rotatably supported on a rotary cylinder and turning over the banknotes,
A plurality of photoelectric conversion elements each having a different monitoring area receive light obtained by irradiating light from a light source to the upper end of the banknote that is being turned over by the suction head, and a lower end of the banknote that is being turned over by the suction head. A photoelectric conversion element for checking the lower edge receives light obtained by irradiating light from a light source to the bottom edge of the banknote, and the denomination of the flipped bill is determined based on the output from each of these photoelectric conversion elements, and the denomination is determined. a ticket type discrimination circuit that outputs a discrimination signal;
The present invention is characterized by comprising a timing signal generating circuit which outputs a timing pulse to the bill type discriminating circuit to operate the circuit in synchronization with each turning of the bill. "Operation" According to the above configuration, each time banknotes are counted, a denomination discrimination signal indicating the denomination of this banknote is outputted from the banknote type discrimination circuit. Therefore, by counting this denomination discrimination signal, it is possible to know the number of banknotes for each denomination, and it is also possible to determine the total amount of the banknote bundle. Further, by comparing the banknotes with a reference banknote (for example, the first banknote counted), it is also possible to discriminate between different types of banknotes. ``Example'' Hereinafter, with reference to the accompanying drawings, a banknote counting machine having a denomination type discriminating device of the present invention will be described in detail based on an embodiment of the banknote counting machine applied to discriminating different types of banknotes. 1 and 2 are a top view and a perspective view showing the schematic structure of the main part of a banknote counting machine, in which a plurality of (five in this example) suction heads 1 are rotatably supported concentrically on the top surface. A banknote bundle holder 3 whose rear end is rotatably supported on one side of the rotary cylinder 2.
An arm member 5 is provided on a free end of the holder 3 near the center of the inner surface of the holder 3, and has a banknote bundle pressing rod 4 implanted therein. Further, an arcuate banknote stopper 6 is provided at the front near the free end of the holder 3.
is installed vertically. On the other hand, a non-contact switch 7 is installed close to the side wall surface of the rotary cylinder 2, and the same number of iron pieces as the suction heads 1, that is, five iron pieces in this example, are installed at equal intervals on the side peripheral wall surface of the rotary cylinder 2. A piece of magnetic material 8 is attached. Next, to explain the operation of the banknote counting machine configured as described above, first, in a steady state where no banknote counting operation is performed, the banknote bundle holder 3 is located at the farthest distance from the rotary cylinder 2, as indicated by the imaginary line in FIG. They are each stably held in the positions shown. On the other hand, when performing a counting operation, first the banknote bundle 9 to be counted is placed on the holder 3 in a predetermined state, and when the holder 3 is rotated clockwise by a predetermined angle, the banknote bundle 9 is held down by a rod. 4, and is set at a position closest to the rotary cylinder 2 as shown by solid lines in FIGS. 1 and 2. Next, in this state, the rotary cylinder 2 is rotated in a predetermined direction (counterclockwise in this example) at a predetermined speed. At this time, this rotary cylinder 2
In synchronization with the rotation of the suction head 1, a suction surface 11 having a suction port 10 approximately in the center thereof faces the suction head 1 at a position closest to the inner surface of the banknote bundle 9 located above the presser rod 4. Then, the innermost banknote is turned over from the banknote bundle 9 and adsorbed, and then the suction force is released and the turned-over banknote is conveyed further backward, so that the banknote is reversed to the rotary cylinder 2. It is rotated at a predetermined speed in the direction, that is, in this example, clockwise. In this way, each banknote in the banknote bundle 9 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 the non-contact switch 7 is closed (or opened) once each time each banknote is turned over. Therefore, those skilled in the art will appreciate that the number of banknotes in the banknote bundle 9 can be easily counted by providing a device so that one counting pulse is generated each time the non-contact switch 7 is closed. As is well known. 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 described above, when the banknote bundle 9 to be counted is placed on the banknote bundle holder 3 of the banknote counting machine, usually only banknotes of the same type are loaded with their loading surfaces, that is, their bottom surfaces aligned. In this embodiment, in the banknote counting machine having the above-mentioned structure, as the rotary barrel 2 rotates, the banknote bundle holder 3 is placed in a predetermined state, and the banknotes are placed between the holder 3 and the presser rod 4. While each banknote in the banknote bundle 9 held between the banknotes and the banknotes is being conveyed so as to be turned over one by one by the action of each suction head 1 on the rotary cylinder 2, for example, as shown in FIGS.
As shown in the figure, transmitted light 15 is obtained by irradiating the upper end of each banknote with the projection light 14 from the projector 13 via the projection lens 12 in response to a synchronization signal with the rotary tube 2 at the moment the banknote is attracted to the suction head 1. A plurality of (four in this example) photoelectric conversion elements 21 provided in the light receiver 21 through the condensing lens 16
A, 21B, 21C, and 21D are arranged to receive light for each denomination as shown in FIG. Shaded areas 17A, 17B, 17C, 17 in Fig. 4
D is an example of each transmitted light monitoring area on the 10,000 yen note, 5,000 yen note, 1,000 yen note, and 500 yen note to be received by each of the photoelectric conversion elements 21A to 21D at this time. Out. FIG. 5 shows that as the rotary tube 2 rotates as described above, each bill in the bill bundle 9, which is clamped and loaded in a predetermined state on the bill bundle holder 3, is turned over one by one by the suction head 1. Each photoelectric conversion element 21A is obtained by receiving the transmitted light 15 obtained by irradiating the upper end of the banknote with the projection light 14 from the light projector 13 by the photoelectric conversion elements 21A to 21D in the light receiver 21 for each denomination. A dissimilar bill discriminating device including a denomination discriminating device according to this embodiment configured to discriminate whether or not a dissimilar bill is mixed in the banknote bundle 9 by using the output electrical signals from 21D to 21D. It is a schematic circuit system diagram. That is, the photoelectric conversion elements 21A, 21B, 21
The respective output electric signals from C and 21D are appropriately amplified through corresponding amplifiers 22A, 22B, 22C and 22D, and then sent to peak point holding circuits 23A and 2, each consisting of an R-S flip-flop circuit, for example.
It is applied to 3B, 23C, and 23D and stored.
The stored signals of these peak point holding circuits 23A to 23D are applied to comparison circuits 24A, 24B, 24C, and 24D each consisting of a threshold circuit, for example, and compared with a predetermined set level for each denomination. These comparison circuits 24A to 24D
An output signal representing each comparison result is applied to the ticket type discrimination circuit 25. On the other hand, as the rotary cylinder 2 rotates, the suction head 1 acts to generate a counting pulse as described above each time one of the banknotes in the banknote bundle 9 loaded onto the banknote bundle holder 3 is turned over by the action of the suction head 1. 6d, e, f, A timing signal generation circuit 27 is provided, for example, consisting of four cascaded D-type flip-flop circuits, which generates four types of timing pulse signals as shown in FIG. From this timing signal generation circuit 27 to FIG.
At the time when the first timing pulse t ₁ as shown in FIG.

[Table] That is, as is clear with reference to FIGS. 3 and 4, the projection light 14 from the projector 13 is turned over by the suction head 1 in the banknote bundle 9 currently loaded in the banknote bundle holder 3. If the banknote is a 10,000 yen note that is illuminated by
The largest amount of received light input is obtained at A, thereby ensuring that the peak point holding circuit 23A is set to the operating state (set state) via the amplifier 22A. At this time, some light receiving input can be obtained from the photoelectric conversion elements 21B to 21D corresponding to the remaining 5,000 yen notes, 1,000 yen notes, and 500 yen notes, but in the case of regular 10,000 yen notes, the peak point is maintained. The circuits 23A to 23D are designed so that they can be set to the active state only in the case of a 10,000 yen note that has been partially worn out without being set to the active state. As a result, the 10,000 yen note is the projected light 1 from the projector 13.
4, the output terminals A, B, C, and D corresponding to the 10,000 yen note, 5,000 yen note, 1,000 yen note, and 500 yen note of the ticket type discrimination circuit 25 is a binary logic level of " ₁ , The device is arranged to derive a series of logical output signals representing the result of the bill type determination. On the other hand, when 5,000 yen is illuminated by the projection light 14 from the projector 13, as is clear with reference to FIG. There is no light receiving input in , and the largest amount of light receiving input is obtained in the photoelectric conversion element 21B corresponding to the 5,000 yen note. Therefore, only the peak point holding circuit 23B is reliably set to the operating state via the amplifier 22B, and the peak point holding circuit 23A is set and maintained to the inoperative state (reset state). At this time, a certain amount of light receiving input can be obtained from the photoelectric conversion elements 21C and 21D corresponding to the remaining 1,000 yen note and 500 yen note, but in the case of a regular 5,000 yen note, it is different from the case of the above 10,000 yen note. Similarly, the peak point holding circuits 23C and 23D are not set to the active state, but can be set to the active state only in the case of a 5,000 yen note that is partially worn out. As a result, when the 5,000 yen note is illuminated by the projection light 14 from the projector 13, a timing pulse t is output from the timing signal generation circuit 27 from each of the output terminals A to D of the note type discrimination circuit 25. ₁
At the point in time when is issued, a series of logic output signals representing the result of bill type discrimination of binary logic levels "0, 1, ×, ×" as shown in the above table are derived. Furthermore, when a 1,000 yen note is illuminated by the projection light 14 from the projector 13, as is clear from FIG. There is virtually no light receiving input to the photoelectric conversion element 21B, and the largest amount of light receiving input is obtained to the photoelectric conversion element 21C corresponding to the thousand yen note. For this reason, the amplifier 22
Only the peak point holding circuit 23C is reliably set to the operating state via C, and the peak point holding circuits 23A,
23B is set and held in an inactive state. At this time, the photoelectric conversion element 21D corresponding to the remaining 500 yen note
However, in the case of a regular 1,000 yen note, the peak point holding circuit 23D is not set to the operating state and is partially printed. It can be set to the active state only for thousand yen notes that have a large depreciation. As a result, when the 1,000 yen note is illuminated by the projection light 14 from the projector 13, the timing pulse t ₁ from the timing signal generation circuit 27 is output from each output terminal A to D of the note type discrimination circuit 25. When this occurs, the binary logic levels “0, 0,
A logical output signal sequence of the bill type discrimination result of 1. Photoelectric conversion element 21 compatible with 500 yen notes
A predetermined amount of light reception input is obtained only in D, and the remaining photoelectric conversion elements 21A to 21C corresponding to the 10,000 yen note, 5000 yen note, and 1000 yen note have virtually no light reception input.
Therefore, only the peak point holding circuit 23D is set to an operating state via the amplifier 22D, and the remaining peak point holding circuits 23A to 23C are set and maintained to be in an inactive state. As a result, when the 500 yen note is illuminated by the projection light 14 from the projector 13, the timing signal generation circuit 27 outputs a timing pulse t from each of the output terminals A to D of the note type discrimination circuit 25. At the time when ₁ is generated, a series of logic output signals representing the result of bill type discrimination of binary logic levels "0, 0, 0, 1" as shown in the above table are derived. On the other hand, if two or more banknotes illuminated by the projection light 14 from the projector 13 are turned over at the same time due to a malfunction of the suction head 1, regardless of the type of banknote, the banknote is damaged, or the banknote is significantly soiled. In the case of abnormality, each photoelectric conversion element 21A to 21
The amount of light received by D is significantly reduced compared to the above-mentioned stationary ticket, or there is virtually no light reception input, and each peak point holding circuit 23A to 23D
is not set to an active state but is kept set to an inactive state. As a result, in such a case, each output terminal A to D of the bill type discrimination circuit 25 receives a timing pulse from the timing signal generation circuit 27.
At the time when _t1 is generated, a series of logic output signals representing abnormal bill type discrimination results of binary logic levels "0, 0, 0, 0" as shown in the above table are derived. Furthermore, in such a case, a signal indicating that there is an abnormality is applied to the terminal 29 from the ticket type discriminating circuit 25 via the signal line 28 to light a lamp or drive another appropriate alarm device. The device is designed to notify that an abnormal bill type discrimination result has been detected. As described above, the timing signal generation circuit 27
Each time the first timing pulse _t1 is generated, a series of logical output signals as shown in the table above are derived from each output terminal A to D of the ticket type discriminating circuit 25 according to the ticket type. The denomination discriminating device is configured according to the configuration described above. Furthermore, in this embodiment, in order to discriminate between different types of bills, the series of logic output signals described above are directly applied to the different types of bills discriminating circuit 30, and the other output terminals A' to D' of the bill type discriminating circuit 25 are also applied. When the second timing pulse _t2 as shown in FIG. At the time when the third timing pulse _t3 as shown in FIG. Thus, the different type of bill discriminating circuit 30 is a delay circuit having a delay time equal to each unit generation period T of counting pulses (equal to the interval at which each suction head 1 turns over each bill) as shown in FIG. 6a. 32, the timing signal _t1 delayed by one period as shown in FIG. The above-mentioned new ticket type discrimination signal train and other output terminals A' of the ticket type discrimination circuit 25
It successively compares the banknote type discrimination signal string applied from D' via the memory circuit 31 with the previous one cycle, and only when a match is not obtained, applies a mismatch output to the terminal 34 via the signal line 33. By lighting a lamp or activating another suitable warning device, it is possible to notify that a different type of banknote is mixed in the banknote bundle 9 that is being counted. As described above, as the rotary cylinder 2 rotates, each suction head 1 sequentially turns over the banknotes one by one, which are loaded in the banknote bundle holder 3 and is turned over one by one, for each banknote in the banknote bundle 9 to be counted. Each peak point holding circuit is activated by the fourth or final timing pulse _t4 in this example as shown in FIG. 23A
~23D is reset to prepare for the next operation. FIG. 6b shows an output electric signal to be derived from the photoelectric conversion element corresponding to the regular denomination loaded in the banknote bundle holder 3 among the photoelectric conversion elements 21A to 21D. In addition, in the case of regular banknotes, as shown by the solid line, the level is sufficient to set the peak point holding circuit corresponding to the same cycle as the counting pulse shown in FIG. In the event of an abnormal state such as the above, the peak point holding circuit normally has a low level as shown by the broken line, which makes it impossible to set the corresponding peak point holding circuit to the operating state. Note that the bill type discriminating circuit 25 for performing the above operation has, for example, an input terminal to which the timing pulse _t1 is applied, and an input terminal to which the corresponding comparison circuit outputs of the comparison circuits 24A to 24D are applied. and having an output terminal connected to each corresponding terminal among the terminals A to D and A' to D'.
It has an input AND circuit, an input terminal connected to each output terminal of these AND circuits, and the signal line 2
One 4-input with output terminals connected to 8
This can be realized using a NOR circuit. The dissimilar ticket discriminating circuit 30 has, for example, four three-input terminals each having an input terminal connected to an output terminal of the delay circuit 32 and a corresponding output terminal among the terminals A to D.
AND circuit, and one 4-input NOR having an input terminal connected to each output terminal of these AND circuits and an output terminal connected to the signal line 33.
Those skilled in the art will readily understand that it can be implemented with circuits. As is clear from the detailed description above, the banknote counting machine having the denomination discrimination device according to this embodiment counts the number of banknotes in the banknote bundle 9 loaded on the banknote bundle holder 3 while counting the number of banknotes in the banknote bundle 9 loaded on the banknote bundle holder 3. Since the denomination of each banknote in the banknote bundle 9 can be determined, for example, when discriminating different types of banknotes, it is possible to easily detect and check the mixture of different types of banknotes by storing a reference banknote and comparing and discriminating with this reference banknote. It is no longer necessary to manually check the contents of a bundle of banknotes to be counted as in the past. For example, it is only necessary to manually read the contents when different types of banknotes are detected. This has the advantage that the banknote counting ability of the counting machine can be significantly improved. FIG. 7 shows a banknote counting operation in which an alarm is generated as described above by using the abnormality signal and the different type bill signal generated from the terminals 29 and 34 of the different type bill discriminating device 35 configured as shown in FIG. FIG. 2 is a schematic block diagram of an additional device section configured to temporarily stop the operation. That is, a banknote counting machine generally has an endless belt 44 wound between a pulley 43 attached to a rotating shaft 42 of a counting motor 41 and the rotary cylinder 2.
1 rotates the rotary tube 2 in a predetermined direction at a predetermined speed as shown by the arrow in the figure, and at the same time rotates each suction head 1 provided on the rotary tube 2 at a predetermined speed in the opposite direction to the rotary tube 2 as shown by the arrow in the figure. While rotating the banknotes, each banknote in the banknote bundle 9 loaded on the banknote bundle holder 3 is sequentially turned over by suction force under the control of the pressure switch 45, starting from the innermost banknote, and then conveyed further to the rear. Let them do it. On the other hand, the non-contact switch 7 installed close to the side circumferential wall surface of the rotary tube 2 is intermittently driven to close in synchronization with the above-described operation of each suction head 1 to turn over each banknote. And the counting pulse generating circuit 2 connected to the banknote counting circuit AC
The input gate circuit 46 of No. 6 is controlled to a closed circuit state in accordance with the operation of the pressure switch 45 and the non-contact switch 7. Said counting circuit
A banknote number display circuit 47 is connected to the output of CA. In FIG. 7, the terminals 29 and 34 of the different ticket discriminating device 35 are connected to a suitable alarm circuit 49 such as a lamp or a buzzer via an OR circuit 48, and also to the input gate circuit 46. Therefore, when the above-mentioned abnormal signal or different type ticket signal is generated, an alarm is generated and the input gate circuit 46 is locked in an open circuit state to cause the counting pulse generation circuit 26 to perform the counting pulse generation operation. An example is shown in which the counting operation of the counting circuit CA and the display content incrementing operation in the display circuit 47 are temporarily stopped. In this case, the bill turning operation by each suction head 1 may be continued to the end regardless of whether or not the above-mentioned abnormality signal and dissimilar bill signal are generated. With this configuration, not only will it be clear where different types of notes exist in the counted banknote bundle, but also the different types of notes can be easily counted by manually counting up to the number corresponding to the count of the counting circuit CA. This has the advantage of being able to detect different types of bills in a banknote bundle more reliably and quickly. FIG. 8 shows a mechanism configured to further discriminate the denomination of a different type of note using a different type of note signal generated from the terminal 34 of the different type of note discriminating circuit 30 configured as shown in FIG. FIG. That is, as is clear with reference to FIG.
When a 10,000 yen note, a 5,000 yen note, a 1,000 yen note, and a 500 yen note are irradiated with the projection light 14 from 3, there is a difference in the amount of light received by the corresponding photoelectric conversion elements 21A to 21D. The number gradually decreases from 10,000 yen notes to 500 yen notes. Furthermore, even if each photoelectric conversion element 2
Even if the amount of light received from the corresponding denominations 1A to 21D is the same, it is a circuit design to have a moderate difference in the amplification degree of the amplifiers 22A to 22D and/or the holding level of the peak point holding circuits 23A to 23D. This makes it possible to provide an appropriate level difference in the different type of note signal applied to the terminal 34 of the different type of note discriminating circuit 30 via the signal line 33 depending on the denomination. 8, comparison circuits 51A to 51D are provided to compare the different type of note signal applied to the terminal 34 from the different type of note discrimination device 30 via the signal line 33 with different set levels depending on the denomination. At the same time, output signals representing the comparison results of these comparison circuits 51A to 51D are applied to bill type display circuits 53A to 53D via bill type storage circuits 52A to 52D, each of which is composed of, for example, an R-S flip-flop circuit. An example is shown in which the bill type storage circuits 52A to 52D are reset at an appropriate time after the bill type display circuits 53A to 53D display the bill type to prepare for the next operation. With this configuration, the different ticket discrimination circuit 3
0 can detect whether or not a different type of note is mixed in the bundle of banknotes being counted. It has the advantage of being able to detect whether it is a 1,000 yen note or a 500 yen note. FIG. 9 shows the terminal 34 of the different ticket discrimination circuit 30.
In addition, an example of a circuit is shown in which a circuit 61 for counting the number of different types of banknotes and a circuit 62 for displaying the number of different types of banknotes are connected in cascade so that it is also possible to detect how many different types of banknotes are mixed in the banknote bundle 9 that has been counted. . FIG. 10 shows a configuration in which the number of input signals to the denomination discrimination device according to this embodiment configured as shown in FIG. 5 is counted and compared with the counting result by the banknote number counting circuit of the banknote counting machine body This figure shows an example of a circuit using the following circuit. That is, in FIG. 10, the amplifiers 22A to 2
A banknote counting circuit 72 is connected to each output end of the 2D via a waveform shaping circuit 71, and this counting circuit 7
The counting output of No. 2 and the counting output of the bill counting circuit CA of the bill counting machine main body (not shown) are compared by the comparison circuit 73 at the time when the pressure switch 45 is turned off after counting is completed. When a matching output is detected from the comparison circuit 73, the opening/closing control circuit (not shown) of the banknote bundle holder 3 is driven via the signal line 74, and when a mismatching output is detected, the opening/closing control circuit (not shown) is driven via the signal line 75. Then, a suitable alarm circuit 76 such as a lamp is driven to generate an alarm, and at this time, the opening/closing control circuit of the banknote bundle holder 3 is not driven to keep the holder 3 closed. It consists of In this case, opening of the holder 3 can be controlled by a normal reset signal. FIG. 11 shows the banknotes loaded in the banknote bundle holder 3 in a predetermined state and turned over one by one from the innermost banknote by the action of the suction head 1. The lower end of each bill in the banknote bundle 9 whose upper end is irradiated by the projection light 14 is further irradiated by another projector, and the reflected light from the banknote lower end projector is used to transmit the dissimilar bill signal and the An example of a circuit configured to improve the reliability of abnormal signals is shown. That is, if it is determined whether there is a different type of note or an abnormal note in the banknote bundle 9 only by the transmitted light from the banknote upper end projector 13 as shown in FIG. There is no problem if the bottoms of the banknotes inside are aligned correctly, but if they are misaligned beyond a certain level, the reliability of the discrimination will be lowered. Therefore, in this FIG. 11, as shown in FIG.
The outputs of the amplifiers 22A to 22D connected to the outputs of the photoelectric conversion elements 21A to 21D without being directly connected to the inputs of the corresponding peak point holding circuits 23A to 23D via the amplifiers 2A to 22D and the banknotes. Four ANDs whose input is the output of the amplifier 22K connected to the output of the photoelectric conversion element 21K arranged to receive the reflected light from the lower end projector.
Circuits 81A to 81D are provided, and the outputs of these AND circuits 81A to 81D are connected to the inputs of the corresponding peak point holding circuits 23A to 23D, respectively. With this configuration, if the banknote bundle 9 loaded on the banknote bundle holder 3 does not include one whose bottom surface, that is, the placement surface is uneven, the photoelectric conversion element 21K is sure to receive a reflection. Since light is received, it is clear that the operation for discriminating different types of bills can be performed in exactly the same manner as in the case of FIG. 5. On the other hand, if the banknote bundle 9 contains banknotes with uneven bottom surfaces, such a phenomenon is completely ignored in FIG. 5, so that the reliability of the dissimilar banknote discrimination operation is poor. On the other hand, in FIG. 11, when the banknote bundle 9 includes banknotes with uneven placement bottom surfaces, the amount of light received by the photoelectric conversion element 21K decreases significantly at this banknote portion, and all AND circuits 81A to 81D It becomes a failure state, and as a result, the photoelectric conversion elements 21A to 2
An abnormality signal is unconditionally generated at the terminal 29 via the signal line 28 regardless of the light receiving state of the 1D. As a result, the circuit shown in FIG. 11 has the advantage of being able to perform a more reliable discriminating operation for different types of bills than the circuit shown in FIG. 5. It goes without saying that the present invention is not limited to only those having the above-mentioned configuration, but can be applied to virtually anything that shares the same technical idea. "Effects of the Invention" As explained above, the present invention outputs a denomination signal corresponding to the denomination every time the banknotes in a bundle of banknotes are counted. By doing so, the following effects can be achieved. Even when different types of notes are mixed in a banknote bundle, it is possible to quickly and reliably detect and check the different types of notes while counting the number of banknotes without manual reading. By determining the denomination, it is also possible to automatically calculate the amount of the banknote bundle.
