In a bulk type automatic deposit machine, when a deposit button is pressed, a door 1 is opened, and the banknotes inserted in a batch from an input slot 1 are taken into the deposit machine by taking belts 3 and 4.

The banknotes taken into the deposit machine are fed out from the payout rows 25 to 9.
The cards are fed out one by one.

The fed banknotes are fed into the discrimination section BD through between conveyance rollers 10 and 11.

The discrimination unit BD discriminates whether a banknote is a normal banknote or a defective banknote.

The banknotes sent out from the discrimination section BD are passed through the rollers 12 and 13.

FIG. 2 is a block diagram of one embodiment of the present invention, with 30
-1 to 30-5 are medium passage detectors, 31-1 to 31-4 are rising detectors, 32-1 to 32-2 are falling detectors, 33 is a feeding timing signal generator, 34
is a timer, 35 is an OR circuit, 36 is a hard timer, 3
7 is a delay circuit, 38 to 46 are AND circuits, 47-1
47-4 are adders, 48-1 to 48-4 are registers, 49 is a comparator, 50-1 to 50-4 are allocation units T1 to T4 are timer tables, 51 is a standard passage time table, 52- 1 and 52-2 are comparison circuits, 53 is an OR circuit, 54 is a timer table selection circuit, and 55 is a timer control table.

Although only one AND circuit 38 is illustrated,
Assuming that the time value of the hard timer 36 is expressed in n bits, there are actually n AND circuits 38.

The same applies to the AND circuits 39, 40, 41, and 42.

The timer 34 is cleared and restarted when a signal is supplied to the hard timer 36, and outputs a pulse signal when the set value is reached.

The hard timer 36 stops when a pulse is input.

After the pulse is input, the delay circuit 37 generates a clear start signal to clear and start the hard timer 36.

The time between the above stop and clear start is practically negligible.

Now, as shown in FIG. 6, it is assumed that three banknotes are conveyed one after another.

It is also assumed that the set value of the timer 34 is greater than any of the time values S1 to S15 in FIG.

When the dispensing timing signal is generated, dispensing of the first banknote is started.

If timer tables T1 to T4 are empty, then
When the payout timing signal is generated, timer table selection circuit 54 selects timer table T1.

Then, a busy mark is placed in the storage area 55-1 of the timer control table 55.

Further, when the payout timing signal is generated, the hard timer 36 starts timing.

When the first banknote arrives at the photo sensor P15, the rise detector 31-1 outputs a pulse signal, and this pulse signal is supplied to the hard timer 36 via the OR circuit 35.

The hard timer 36 stops and its count value S1 becomes A.
The signal is sent to the adder 47-1 via the ND circuits 38 and 39.

The timer tables T1 to T4 have a configuration as shown in FIG. 3, and nothing is written at the time of starting bill conveyance.

The contents of the first address of timer table T1 are stored in register 48.
-1 and is added to the clocked value S1, but since the contents of the register 48-1 is zero, the clocked value S1 is directly sent to the work allocation section 50-1.

The allocation units 50-1 to 50-4 write the adder output at the address next to the address where the pass mark has been set.

However, if pass marks are not set at all addresses, the adder output is written in the first address.

In this case, since no passing mark is attached to any of the first to sixth addresses of the timer table, the timed value S1 is written in the first address of the timer table T1.

The allocation units 50-2 to 50-4 have the same functions as the allocation unit 50-1.

Passage marks are written to the timer table as follows.

First, the timer table in use is selected, and then, based on the type of input signal input to the hard timer 36, the corresponding address is selected.

Then, the contents of the selected address of the timer table in use are read out and inputted to the comparator 49.

Comparator 49 selects the largest value and sends a pass mark to the timer table with the largest value.

This passing mark is written in the O-th bit position of the address next to the address where the passing mark is set.

At this address, a passage mark is written at the first address of timer tape /L/T1.

When the first banknote arrives at the photo sensor Psi 6, the rise detector 31-2 outputs a pulse signal, which causes the hard timer 36 to stop.

Then, the time value S2 is sent to the adder 47-1 and added to the contents of the second address of the timer table T1, and the addition result S2 is entered in the second address of the timer table T1. Stands in the bit position.

When the rear end of the first banknote passes the photo sensor PS16, the fall detector 32-1 outputs a pulse signal and the hard timer 36 stops.

The time value S3 is then stored at the third address of the timer table T1.

When the banknote passes the photo sensor PS16, feeding for the next banknote is started.

When the feeding timing signal indicating the start of feeding is generated,
The count value S4 of the hard timer 36 is stored in the timer table T.
1, the timer table T2 is assigned to the second banknote.

When the second bill arrives at the photo sensor PS15,
The clock value S5 of the hard timer is added to the adder 47-1.47-
Sent to 2.

The adder 47-1 adds the content S4 of the address next to the address where the passing mark is set, that is, the fourth address, and the time value S5.

As a result, S4+85 is written at the fourth address.

The time value S5 is entered at the first address of the timer table T2, and a pass mark is placed at the O-th bit position.

When the first bill arrives at the photo sensor PS23,
The clock value S6 is sent to the adder 47-1.47-2.

Adder 47-1 adds the contents of timer table T1 S4+S
5 and the clocked value S6 are added.

The 4th address of the timer table T1 contains the total clock value S4+
S5+S6 is entered and a passing mark is placed.

The clock value S6 is written in the second address of the timer table T2.

At the same time as the passing mark is set at the fourth address of the timer table T1, the storage area 55- of the timer control table 55 is set.
1, the discrimination results are entered.

Since it is assumed that the first bill is a normal bill, no defective mark is placed in the storage area 55-1.

When the second bill arrives at the photo sensor PS16,
The count value S7 of the hard timer 36 is stored in the timer table T.
It is entered at the 6th address of 1.

The allocation unit 50-1 stores the storage area 5 of the timer control table 55.
If a defective mark is not entered in 5-1, the adder 47-1 is placed in the 6th address after the passing marker is set in the 4th address.
Fill in the output of

If a defective mark is written, the output of adder 47-1 is written to the fifth address.

Note that the allocation section 50-2.50-3.50-4 also has a similar function.

The second address of timer table T2 has a total of 36+ clock values.
87 is entered and a passing mark is placed.

When the second bill passes through the photo sensor PS16,
The 6th address of the timer table T1 contains the total clock value S7+
88 is entered.

The clock value S8 is entered at the third address of the timer table T2, and a passing mark is set.

When the second bill passes through the photo sensor PS16,
A command is given to dispense the third bill, and a dispense timing signal is generated.

When the payout timing signal is generated, the total clocked value S7+S8+S9 is written in the 6th address of the timer table T1, and the clocked value S9 is written in the 4th address of the timer table T2.
is entered.

Then, for the third banknote, the timer table T3
will be assigned.

When the first bill arrives at the photo sensor PS42,
The 6th address of the timer table T1 contains the total clock value S7+
S8+S9+S10 is entered and a passing mark is placed.

The total timed value is 89+ in the 4th address of timer table T2.
810 is entered.

The clock value S10 is entered at the first address of the timer table T3.

Each of the timer tables T1 to T4 clears its own contents and outputs a clear signal when a pass mark is placed at the fifth or sixth address.

Since the pass mark has been set at address 6 of the timer table T1, the timer table T1 outputs a clear signal.

This clear signal causes the memory area 55-1 allocated to the timer table T1 of the timer control table 55 to be cleared.
The contents of are cleared.

Additionally, timer table T1 is also cleared. When the third banknote arrives at the photo sensor PS15, the total timed value S9+S10+S11 is added to the fourth banknote of the timer table T2.
It is entered in the street address.

The first address of the timer table T3 contains a total of 81 clock values.
0+811 is entered and a passing mark is set.

When the second bill arrives at the photo sensor PS23,
The total timed value S9+S10+S11+S12 is entered in the fourth address of the timer table T2, and a passing mark is set.

When a pass mark is set at the fourth address of the timer table T2, the discrimination result is written into the storage area 55-2 of the timer control table 55.

Since the second banknote is assumed to be a defective banknote, a defective mark is placed in the storage area 55-2.

The clock value S12 is written in the second address of the timer table T3.

When the third bill arrives at the photo sensor PS16,
A clock value 813 is entered in the fifth address of the timer table T2, a total clock value 812+813 is entered in the second address of the timer table T3, and a passing mark is set.

When the second bill passes through the photo sensor PS25,
The 5th address of the timer table T2 contains the total time value S1.
3+814 is entered and a passing mark is placed.

The clock value S14 is entered at the third address of the timer table T3.

Timer table T2 outputs a clear signal, thereby clearing storage area 55-2 assigned to timer table T2 of timer control table 55.

Timer table T2 is also cleared.

When the third banknote passes the photo sensor 16, the total time value 814+81 is displayed at the third address of the timer table T3.
5 is entered and a passing mark is placed.

Thereafter, when the third bill arrives at the photo sensor PS23, a passage mark is placed at the fourth address in which the required time is written.

Assuming that the third bill is a normal bill, when the tip of the third bill reaches the photo sensor PS42, the hard timer 3
The clock value of 6 is entered at the 6th address and a passing mark is set.

If the third banknote is a defective banknote, when the banknote passes the photo sensor PS25, the hard timer 36
The measured value is entered at address 5, and a passing mark is placed.

The standard transit time table 51 has a configuration as shown in FIG.

In FIG. 4, A indicates the maximum standard value of the time from when the banknote is fed until it arrives at the photo sensor PS15,
l indicates its minimum standard value.

B indicates the maximum standard value of the time it takes for a bill to move from photo sensor Psis to Psi 6, and ``B'' indicates the minimum standard value.

C indicates the maximum standard value of the time for removing and removing the banknote after it arrives at the photo sensor PSI 6, and C' indicates the minimum standard value.

D is a photo sensor after the banknote passes through the photo sensor PS16.
It shows the maximum standard value of the time until it arrives at sensor PS23, and %D' shows its minimum standard value.

E indicates the maximum standard value of the time from when the bill arrives at photo sensor PS23 until it passes photo sensor PS25, and E' indicates the minimum standard value.

F is the maximum standard value of the time required for the leading edge of the bill to move from photo sensor PS23 to PS42, and F4 indicates the minimum standard value.

Bill jam detection is performed as follows.

Now, suppose that the first banknote arrives at the photo sensor PS16, as mentioned earlier, the timer table T1
A passage mark is placed at the second address where the clock value S2 is entered.

When the passage mark is set, the time value S2 is transferred to the comparator circuit 52.
-1,522.

On the other hand, since the bill has arrived at the photo sensor PS16, the maximum standard passage time B and the minimum standard passage time y are read from the standard passage time tape A151 and sent to the comparison circuits 52-1 and 52-2, respectively.

and S2>B or S2<B' In this case, it is determined that the banknote is jammed.

The timer 34 is used in the following cases.

Now, in FIG. 6, it is assumed that the first bill that has arrived at the photo sensor P16 is jammed and does not pass through the photo sensor 16 no matter how long it takes.

In this case, the timer 34 outputs a pulse signal, and the clock value Sn of the hard timer 36 at this time is sent to the adder 47-1.
The contents of the address and the clocked value Sn are added, and the addition result is written in the third address.

When a pulse signal is generated from the timer 34, by comparing it with the standard passing time, the maximum standard passing time C and the minimum standard passing time C' are read out, and the third address ( In this case, the third address is compared with the contents of the third address (which is the address next to the address where the pass mark has been set), and jam detection is performed.

If time information is written in all of timer tables T1 to T4, the contents of the address next to the address where the passing mark in timer table T1 is set are compared with the corresponding standard passing time, and the timer table・The contents of the address next to the address marked with a passage mark in table T2 are compared with the corresponding standard passage time, and the standard passage time corresponding to the contents of the address next to the address marked with a passage mark in timer table T3 is compared. compared to time.

The same applies to timer table T4.

Note that, instead of the timer 34, an interval timer that outputs a signal periodically can also be used.
