It is an integer of 0. ) Is calculated and stored, and the reference data Dr is calculated based on the average data D _{n, i} calculated by the average data calculation storage unit 51.
Reference data calculation storage means 52 is provided for calculating and storing _{n, i} , reference maximum transmitted light amount data Dmax _{n, i} and reference minimum transmitted light amount data Dmin _{n, i} according to the following equations, respectively.

Dr _{k, i} = (Dr _{k−1, i} + D _{k, i} ) / 2 where k is an integer of 2 or more, and Dr _{1, i} = D _{1, i} .

Dmax _{n, i} = Dr _{n, i} + D r _{n, i} / a D min _{n, i} = D r _{n, i} + D r _{n, i} / b where a and b are values determined experimentally.

Further, the abnormality determination means 43 includes the average value data D _{n, i} calculated by the average value data calculation storage means 51 and the reference maximum transmission light quantity data Dmax _n and the reference minimum transmission light quantity data calculated by the reference data calculation storage means 52.

k, i} and reference maximum transmitted light amount data Dmax _{k−1, i} and reference minimum transmitted light amount data Dmin _{k−1, i.} If 53 determines that D _{k, i} > Dmax _{k−1, i} , the amount of light transmitted through the voting paper S is excessive, and it is considered that the voting paper S is blank or has poor printing. The average value data comparing means 53 outputs an abnormal signal to the timing means 54, and when it is determined that Dmin _{k−1, i} > _{Dk, i} , the amount of light transmitted through the voting paper S is too small. Since it is considered that the voting paper S has a printing failure, the voting paper S is double-fed, or a part of two or more voting papers S is sent in an overlapped manner, The value data comparing means 53 outputs an abnormal signal to the timing means 54. On the other hand, when it is determined that Dmin _{k−1, i} ≦ D _{k, i} ≦ Dmax _{k−1, i} , the voting paper S is determined to be normal and the feeding thereof is also determined to be normal. Data comparison means 53
Does not output an abnormal signal.

Further, the abnormality judging means 43, the average value data D _n of all detection section S1~S10 ballot _S, by adding _i, the sum value data calculating storing means 55 for calculating a sum value data AD _n, adding based on the sum value data AD _n calculated by the value data calculating storage unit 55, the reference additional data ADr _n, the reference additional maximum transmission light data Admax _n and the reference additional minimum transmission light data ADMIN _n, respectively, according to the following equation And a reference addition data calculation storage means 56 for calculating and storing.

_{ADr K = (ADr k-1} + AD k) / 2 where a ADr ₁ = AD _1.

Here _{ADmax n = ADr n + ADr n} / c ADmin n = ADr n -ADr n / d, c and d is a value determined experimentally.

Further, abnormality determination unit 43, for each ballot S, the addend data AD _k, the reference additional maximum light transmission data Admax _k-1
And an additional value data comparing unit 57 for comparing the reference additional minimum transmitted light amount data ADmin _k-1 . If the additional value data comparing unit 57 determines that AD _k > ADmax _k-1 , voting is performed. The amount of light transmitted through the sheet S is excessive, and the voting sheet S
Is considered blank or the voting paper S has a printing failure, so the added value data comparing means 57 outputs an abnormal signal to the timing means 54, and ADmin _k-1 >
If it is determined to be AD _k , the amount of light transmitted through the voting paper S is too small, the voting paper S has a printing failure, the voting paper S is double-fed, or two or more voting papers are used. Since it is considered that a part of S is sent in an overlapping manner, the added value data comparing means 57 outputs an abnormal signal to the timing means 54. On the other hand, when the added value data comparing means 57 determines that ADmin _k-1 ≤ AD _k ≤ ADmax _k-1, it is determined that there is no abnormality in the voting paper S, and that there is no abnormality in the feeding. Thus, the added value data comparing means 57 does not output an abnormal signal.

Further, the abnormality judging means 43 based on the output signal of the first sensor 8, and calculates the length data L _n ballot S, the length data calculation storage unit 58 for storing, this length data calculating storage means 58 Based on the length data L _n of the voting paper S calculated by
Reference length data calculation storage means 59 is provided for calculating and storing reference length data Lr _n , reference minimum length data Lrmin _n, and reference maximum length data Lrmin _n according to the following equation.

Lr _K = (Lr _k-1 + L _k ) / 2 where Lr ₁ = L ₁ .

Here _{Lrmax n = Lr n + Lr n} / e Lrmin n = Lr n -Lr n / f, e and f is a value determined experimentally.

Furthermore, the abnormality determination means 43 is provided for each ballot S
The length data L _k, has a reference maximum length data LRmax _k-1 and the reference minimum length data Lrmin _k-1 and the length data comparing means 60 for comparing, the length data comparing means 60, L _k > Lrma
If it is determined to be x _k−1 , it is considered that the length of the detected voting paper S is excessive, and it is considered that two or more voting papers S have been partially overlapped. Comparison means 60
Outputs an abnormal signal to the timing means 54, and
If it is determined that min _k−1 > L _k , the detected ballot S
Is too small and the ballot S is considered to have been cut or broken, so the length data comparison means 60 outputs an abnormal signal to the timing means 54. On the other hand, the length data comparing means 60
If it is determined that _k-1 ≦ L _k ≦ Lrmax _k−1, it is determined that there is no abnormality in the voting paper S, and that there is no abnormality in the feeding thereof. Does not output a signal.

As described above, when any one of the average value data comparing unit 53, the added value data comparing unit 57, and the length data comparing unit 60 detects an abnormality of the voting paper S or an abnormality of the feeding of the voting paper S, the abnormality is detected. The signal is output to the timing means 54.

When the timing means 54 receives an abnormal signal before a predetermined time elapses after the feeding operation of the voting paper S is started,
A voting paper collection signal is output to the solenoid 45, the sorting fork 16 is driven, the voting paper S is collected in the collection passage 17, a delivery signal is output to the drive control means 42, and the delivery roller 6 is rotated again. Then, when the voting paper S is fed out, and when an abnormal signal is received after a lapse of a predetermined time from the start of the voting paper S feeding operation, the drive control means 42 sends a drive inhibition signal to the counter 41. A count prohibition signal is output to the display means 44 to output an abnormality display signal, and the drive motor 21 is stopped, and the display means 44 displays that an abnormal state has occurred. Also, the counter 41
Is configured such that when the count prohibition signal is input from the timing means 54, even if the issuance signal is input from the second sensor 19, the total number of issued sheets and gender are not increased.

When the operator presses the male key 40a or the female key 40b, the voting paper issuing machine 1 including the voting paper discriminating apparatus according to the embodiment of the present invention configured as described above,
The operation of issuing the voting paper S is started, and an operation start signal is sent to the drive control means 42, and the drive control means 42
As the 21 is driven, a display signal is sent to the display means 44, and the display means 44 displays whether one of the man and the woman has been designated. At the same time, a count signal is also output to the counter 41, but as described above, the counter 41
The counting operation is not performed until the issuance signal is input from.

In this way, when the drive motor 21 is driven, the drive pulley 23 rotates clockwise in FIG.
The endless belt 26, the pulley 25, and the pulley 20 wound around 23 each rotate clockwise, and the pulley 24 rotates counterclockwise, and as a result, a feeding roller coaxially and integrally provided with the pulley 20. 6 rotates clockwise, the friction portion 6a of the feeding roller 6 comes into contact with the uppermost voting paper S of the voting paper S placed on the mounting table 5a of the voting paper storage 5, and the friction portion Due to the frictional force between 6a and the upper surface of the voting paper S, the uppermost voting paper S is sent out to the transport path 7.

On the other hand, as the pulley 24 rotates counterclockwise, the pulley 29 coaxially and integrally provided with the pulley 24 also rotates counterclockwise in FIG. Belt 30, pulley 27 and pulley 28
Also rotates counterclockwise. As a result, the first transport roller 10 provided coaxially and integrally with the pulley 27 and the second transport roller 12 provided coaxially and integrally with the pulley 28
Both rotate counterclockwise, and the first
The first transport roller 9 pressed by the transport roller 10 and the second transport roller 11 pressed by the second transport roller 12
Rotates clockwise.

When the voting paper S fed from the voting paper storage unit 5 by the feeding roller 6 passes through the first sensor 8, the light emitting element 8a emits light, and the amount of light transmitted through the voting paper S is detected by the light receiving element 8b. Then, the transmitted light amount detection signal is sent to the abnormality determining means 43. The voting paper S further includes first transport rollers 9 and 10 and second transport rollers 11 and 12.
As a result, the transport speed is accelerated, and the transport path 7 is sent toward the ballot paper issuing port 18.

As described above, the average value data comparing means 53, the added value data comparing means 57, and the length data comparing means 60 of the abnormality determining means 43 determine whether or not the voting paper S is abnormal and whether or not the voting paper S is abnormally transmitted. Is determined, and when it is determined that there is an abnormality, an abnormality signal is output to the timing means 54. The timing means 54 outputs a voting paper collection signal to the solenoid 45 and drives the sorting fork 16 when receiving an abnormal signal before the elapse of a predetermined time from the start of the operation of feeding out the voting paper S, thereby driving the sorting fork 16 and voting. The paper S is collected in the collection passage 17, and a feed signal is output to the drive control means 42, and the feed roller 6 is rotated again to feed the voting paper S. On the other hand, when an abnormal signal is received after a lapse of a predetermined time from the start of the feeding operation of the voting paper S, whether the voting paper S has reached just before the distribution fork 16 or
Alternatively, since the distribution fork 16 has been passed, it is impossible to drive the distribution fork 16 to collect the voting paper S in the collection passage 17, and therefore, the timing means 54 is controlled by the drive control means 42 To output a drive inhibition signal to stop the rotation of the feed roller 6, the first transport rollers 9, 10 and the second transport rollers 11, 12. Then, when the voting paper S protrudes outside from the voting paper issuing opening 18, the voting paper S is taken out from the voting paper issuing opening 18, and
On the other hand, when the voting paper S remains in the voting paper issuing machine 1, the lock mechanism 4 is released, the upper cover 3 is removed, and the handle 32 is pulled up, so that the transport path cover 31 is removed.
Is opened, and the ballot S is taken out and collected. The timing means 54 outputs a drive prohibition signal to the drive control means 42 and simultaneously outputs an abnormality display signal to the display means 44,
At the same time, the fact that an abnormal condition has occurred is displayed at 44 and a count prohibition signal is output to the counter 41. As aforementioned,
The counter 41 is configured to detect that the voting paper S has been pulled out by the second sensor 19 and to increase the number of voting papers S issued one by one when an issuance signal is input. When the count prohibition signal is input from the timing means 54, the voting paper S pulled out from the voting paper issuing port 18 is collected. Absent.

On the other hand, when the abnormality determining means 43 determines that the voting paper S is normal and the feeding of the voting paper S is also normal, the voting paper S is left as it is by the second transport rollers 11 and 12. A fold is formed at the center in the length direction, and the fold is sent to the ballot paper issuing port 18. The drive motor 21 stops when the feeding roller 6 makes one rotation.
When the drive motor 21 stops, a part of the voting paper S protrudes out of the voting paper issuing machine 1 from the voting paper issuing port 18 and stops in a state where it can be pulled out from the outside. The transport mechanism is designed so that, in part, it is located between the issuing element 19a and the light receiving element 19b of the second sensor 19.

Thereafter, when the voting paper S is removed from the voting paper issuing port 18, the voting paper S is no longer present between the issuing element 19a and the light receiving element 19b of the second sensor 19, so that the second sensor 19 Detecting the removal of the sheet S, outputting an issue signal to the counter 41 and outputting a reset signal to the drive control means 42.

When the counter 41 receives the issuance signal from the second sensor 19, if no count prohibition signal is received from the abnormality determination means 43, the counter 41 issues either the gender according to the count signal input from the key 40a or 40b. The number is increased by one and the total number of issued sheets is increased by one. Further, an issued number signal is output to the display means 44 to change the number display on the display means 44. Here, the count signal is the second sensor
Until the issuance signal is input from 19, it is possible to change, so even if you mistakenly press the keys 40a, 40b, before extracting the voting paper S, press the keys 40a, 40b again. The number of issued sheets can be correctly counted for each gender.

Further, the drive control means 42 is configured not to drive the drive motor 21 until a reset signal is input from the second sensor 19, so that the drive motor 21 rotates the feeding roller 6 once. The voting paper S is sent to a predetermined position and stopped, and before the voting paper S is pulled out from the voting paper issuing port 18, the operator mistakenly presses the key 40 and the drive motor 21 is not driven even if the key 40 is pressed again. Thus, the voting paper S is reliably prevented from being fed out of the voting paper storage unit 5.

As described above in detail, according to the present embodiment, the voting paper S is determined based on the average transmitted light amount, the added value of the average transmitted light amount, and the length of each section S1 to S10 of the voting paper S issued immediately before.
Of the voting paper S and the feeding of the voting paper S are discriminated, so that even if the type of the voting paper S is changed, the voting paper S can be accurately detected without making any change to the apparatus itself.
And an abnormal feeding of the voting paper S can be determined.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention described in the claims, which are also included in the scope of the present invention. Needless to say.

For example, in the above embodiment, the transmitted light amount of the voting paper S is detected by dividing it into ten sections S1 to S10, but the number of sections is set to be less than 10 even if it exceeds ten. You may.

Further, in the above embodiment, when the abnormal signal is input before the elapse of the predetermined time,
Turn on the solenoid 45, and with the sorting fork 16,
The voting paper S is collected in the collection passage 17, and when an abnormal signal is input after a predetermined time has elapsed, the drive motor 21 is stopped by the drive control means 42, and the upper cover 3 and the transport path cover 31 are opened. Thus, the voting paper S is taken out from the transport path 7 or from the voting paper issuing port 18 and collected. However, without providing the timing means 54, for example, an abnormal signal from the average value data comparing means 53 Is input to the solenoid 45, the voting paper S is collected by the sorting fork 16 into the collection passage 17, and the abnormal signals from the added value data comparing means 57 and the length data comparing means 60 are
Input to the drive control means 42, stop the drive motor 21,
The voting paper S may be collected. Furthermore, when the distance between the first sensor 8 and the distribution fork 16 can be arranged to be sufficiently long, the average value data comparing means 53, the added value data comparing means 57 and the length All the abnormal signals from the data comparing means 60 are input to the solenoid 45, and
The voting paper S may be collected in the collection passage 17.

Further, in the above-described embodiment, a description has been given of a case where the present invention is applied to the voting paper discriminating apparatus of the voting paper issuing machine 1. However, the present invention is not limited to such a case, and includes a bill and the like. The present invention can also be applied to the determination of abnormalities of other paper sheets and the determination of abnormal feeding.

Alternatively, it is also possible to determine only one of the determination of the abnormality of the sheet or the abnormal feeding of the sheet.

Furthermore, each unit described in the claims does not necessarily mean a physical unit, and the present invention also includes a case where the function of each unit is realized by software. For example, the function of one unit may be realized by two or more physical units, or the function of two or more units may be realized by one physical unit.

Effects of the Invention According to the present invention, it is possible to accurately detect whether or not a paper sheet is of a specific type and / or abnormal feeding such as double feeding of the paper sheet for various kinds of paper sheets. It is possible to provide a paper sheet discriminating apparatus.
