Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a banknote discriminating device that is used in a banknote counting machine or the like and determines whether the banknote is gold based on the longitudinal length of the banknote conveyed in the lateral direction.

Normally, banknotes are stored in a banknote counting machine installed in an automatic teller machine or a banknote discrimination ice installed in an automatic teller machine in order to shorten the processing time and the length of the device in the depth direction. Therefore, even when determining the denomination from the length of a bill, conventionally the determination was made by detecting the length in the width direction. However, depending on the banknote, even if the denomination changes, the length in the transverse direction may change, and only the length in the longitudinal direction changes.In such cases, the banknote must be conveyed in the transverse direction. However, the Kasa-mai method, which detects the length in the transverse direction, was not able to determine the denomination, and was very difficult.

Therefore, the present invention aims to provide a two-way system for banknote conveyance routes.

A seven-meter array consisting of a plurality of light emitting elements and light receiving elements is provided between and across the conveyance route, and the longitudinal length of the banknote is determined from the output state of the light receiving elements to determine the denomination. It is an object of the present invention to provide a banknote discriminating device configured in this way, thereby eliminating the above-mentioned drawbacks.

The present invention will be specifically described below based on embodiments shown in the drawings.

As shown in Figs.
15' are provided at the same position on both sides of route 7A and FB, and in each sensor row t5.1s', a plurality of light emitting elements tSa are arranged to cross route 1B at right angles. The light-receiving part Sad includes a light-emitting part 15b and a plurality of light-receiving elements 15C arranged to sandwich the light-emitting part tsb and the light-emitting part 7B, and facing each detection element l5aK. .

Each light receiving element 15cK of the sensor rows 15, 16' converts the light receiving signal into a binary signal through a comparator 1@, as shown in the stripe diagram 2. 1S is connected, flip-flop IT

is connected.

Since the present invention has the above configuration, when counting and dispensing a predetermined amount of banknotes 5.5' to a customer, the company first rotates and removes the scraping roller to remove the banknotes in the banknote storage s3. The reduced number of S is fed out one by one into the banknote conveyance route IA, and conveyed to the banknote pool s12 via the row 28, belt 10, etc. via the banknote TD. When a predetermined number of banknotes 5 have been conveyed to the pool w612, the row 26 is stopped and the roller 6'' is driven to rotate, and the banknotes 5' in the storage box 3' are conveyed one by one by a predetermined number. The banknotes are transported from LB to the pool section 12 via route TDtM. At this time, it is determined whether the banknotes 5.5' that are delivered from the storage box 3%s' i=mb to routes 7A and 7B are banknotes of the correct denomination. However, the next banknote 5.5' that is dispensed from the storage box 3%3' in ?A%7B is banknote size 111i1t1s.

[As shown in Fig. 4, the light receiving element 1sCt'i, *perpendicular to the feeding direction, is selectively blocked by one banknote 5, S', and the direction 81 of the shielded element 15c is from 101 to 11''. direction, that is, in the longitudinal direction of the banknote 5, S', depending on the length L2 of the banknote 5.5' in the longitudinal direction,
Light receiving element IS where light 14 from light emitting element 15m is blocked
The number of C changes. The output 81 of the light receiving element 15C is 111
Then, the output 81 is waveform-shaped by the comparator 18, and the output 82 of the flip-flop 1T corresponding to the element 15CK whose output 81 becomes Ill is set to '1'& C-. On the other hand, when the banknote 5.5' enters the sensor row 15.15' and the output 81 of at least one light receiving element ISC changes to Ill, the output S3 of the flip-flop 26 changes to 11mK via the zero circuit 18. The banknotes 5 and S' are further conveyed in the direction C, and one sensor row Is, Is'
When all elements 15C have returned to 1olK by 9%, NOT[a[
2S (the D output 84 goes from @01 to Ill), and the output 85 of the AND circuit 21 goes from IOI to 111, driving the gate circuits 19 and 21. Then, the gate circuit 11t
-, the outputs 82 of all seven lip-flops 110 are latched into the shift register 20, and the tarock pulse CP output from the oscillator 3@ is input to the shift register 20 via the gate circuit 2s, and the latched contents are sent to the counter 21. K11 is read out. The counter 21 counts the number at which the output 82 of the flip-flop 11 becomes 111, that is, the number of light-receiving elements 11c blocked by the banknote 5.5'.
The number expressed as is large. ), is outputted to the correction circuit 23 as an output S6. On the other hand, correction - road 23, output saK%am
s and S' have entered the sensor array IS and 15' in a diagonal manner. When entering the Senna row 1s% 151, the light receiving element of the Senna row 15.1%' will measure the projected length l, 21 of the ISC banknote 5% 5' in the red stamp C direction9, and the accurate longitudinal direction. It becomes impossible to measure the length L2. Then, as the obliquely traveling banknote 5.5' crosses one of the innermost light receiving elements ISC, ISC' of the sensor array 15.15', the light is blocked, and the output 81 becomes 1.
When the value reaches 111, the counter 33 is driven via the %OFL circuit 31, and the banknote 5.5' that is obliquely fed to the banknote is conveyed in the C direction, and the innermost element 15C%ISC' is both shielded from light. When the outputs 81 are both K@1''K, the AND circuit 35 is opened via the %AND circuit 32, and the contents of the counter 33 at that point are outputted to the correction circuit 23 as the output S7. The distance L3 between the innermost light receiving elements 15C and 115C' is constant and To
In addition, since the conveyance speed of the banknotes 5.5' in the conveyance routes 7A and 7B is also constant, one of the light receiving elements 15C is blocked by the banknotes 5.5', and in the next i, both the light receiving elements l
The time until both 5CSISG' are blocked is determined by counting the clock pulse CP, and the output S
7, the correction circuit 23 can immediately calculate the amount of skew of the banknote 5.5' with respect to the transport direction.

Therefore, the correction circuit 23 outputs the measured banknote 5 from the output 86.
．． The 0 judgment circuit 22KFi calculates the length in the longitudinal direction of the banknote 5', corrects the value appropriately using the % output S7, and outputs the result to the judgment circuit 22 as the output S8.
The exact length L2 in the longitudinal direction of 5' is stored as standard data for each denomination, and this data is output and the calculation lengths are compared, and the output 88 and the stored 41111 data are read and output. By comparing the two, transport route 7
The denomination of banknote 5.5' among banknotes A and 7B can be immediately determined. In this way, when it is determined that the banknotes 5 and 5' fed out from the banknote storage 5s13' are banknotes of the correct denomination, the gate 11 is rotated in the direction B,
The banknotes 5 and S' pooled in the banknote pool section 12 are collectively discharged to the banknote discharge port 8 via the transport route IL) and 7I3, but it is determined that the banknotes 5 and 5' are not of the correct denomination. If so, the pool *t 20 banknotes 5.51 are put into the reject box 8aGPK all at once, and the banknote counting operation is restarted from the beginning by driving the rollers 6, 6', etc. again.

In addition, although the above-mentioned example described the case where there are two types of denominations to be determined, the number of denominations to be determined is not limited to two types.
It goes without saying that jin can be of any number of types.

In this case, multiple pieces of standard length data corresponding to the denomination are stored in the discriminator, read out and compared one after another, and the denomination corresponding to the collar standard data with the least amount of error is selected for the corresponding denomination. Display and output data indicating the species.

In the banknote stitch counting device 1, since the number of denominations to be checked is limited to one denomination, only one piece of marking data is required for inspection, and this can be achieved with a small circuit.

As explained above, according to the present invention, the banknote transport route)
A sensor array 15.15' consisting of a plurality of light emitting elements 1sa and light receiving elements 15C is provided on both sides of the transport routes 7A and 7B, sandwiching the transport routes 7A and 7B and crossing the routes 7A and 7B. Banknote 5% 5' from the output state of the light receiving element ISC
Since the length Ll in the longitudinal direction is determined and the denomination is determined, the length Ll in the transverse direction is fixed regardless of the denomination. It becomes possible to make a determination without changing the conveyance system.
