FIG. 4 shows a block diagram of a control circuit of the coin processing device. The CPU 41 controls each circuit device according to a program stored in the ROM 42, and outputs its control data to the RA.
It is stored so that it can be read by M43.

In particular, when the coin is inserted into the slot 11, the CPU 41 controls the input side conveyor belt 16 at a low speed while the coin is discriminated by the discriminating section 13, and the coin discriminating section 13 is controlled. In order to prevent the discrimination failure due to the feeding of two coins, and the discrimination unit 13 is in the discrimination waiting state in which the next coin can be received, the input side conveyor belt 16 is immediately switched to the high speed conveyance to discriminate the next coin. The part 13 is provided with a transfer speed switching control function that allows the parts to be quickly taken in. Thereby, the transfer processing speed of the inserted coins can be increased, and the transfer processing time of the coins is shortened.

Further, the CPU 41 conveys the sorting-side transport belt 20 at a low speed when the sorted coins are fed out from the sorting section 13 and while the preceding coins are sorted in the sorting-side transport passage 14 at the subsequent stage. Control the coins into the passage 14
When the sorting side transport passage 14 is in the sorting standby mode in which the next coin can be received, the sorting side transport belt 20 is immediately switched to the high speed transport and the next coin is fed. Each of the storage sections 22 to 25 is provided with a transfer speed switching control function for swiftly sorting processing. Thereby, the distribution processing speed of the coins delivered from the discriminating unit 13 can be increased, and the distribution processing time of the coins can be shortened.

The timer 44 counts the time required for the regular transfer of the coin inserted into the slot 11 to the discriminating section 13, and detects the presence or absence of a coin jam and the next coin based on this time.

The coin processing operation on the input side of the coin processing device thus configured will be described with reference to the flowchart of FIG. Now, when a coin is inserted into the slot 11, the first detection sensor S1 detects the inserted first coin,
Based on this detection signal, the CPU 41 drives the loading-side transport belt 16 at a high speed and sets the timer 44 so that the loaded first coin is transported to the discrimination section 13 at a high speed (steps n1 to n4). ).

At this time, if the coins are not taken into the discriminating section 13 within a certain time after the input side conveyor belt 16 starts moving, the CPU 41 determines that the coins are jammed during the transportation, and the coin jamming canceling process is performed. Done (steps n5 to n6
).

When a coin is taken into the discrimination section 13, the CPU 41
Controls the feeding side conveyor belt 16 at a low speed so as to guide the next coin one by one to the discrimination section 13 (step n7).
).

During this transportation, coins are subsequently inserted,
If two coins are successively taken into the discriminating unit 13 by mistake, the inserted coins are immediately returned (steps n8 to n10).

Further, when the coin taken into the discriminating section 13 is fed out to the subsequent stage, the next discrimination processing in the discriminating section 13 is permitted, so that the CPU 41 conveys the input side conveyor belt 16 from low speed conveyance to high speed conveyance. , The next coin is immediately taken in, and the next discrimination processing is executed. In this way, by discriminating between high-speed conveyance and low-speed conveyance and repeating according to the processing state of the discrimination section 13, the discrimination processing speed of coins can be increased (step n11).

When the next coin is no longer recognized on the input-side transport passage 12, the input-side transport belt 16 is driven for a certain period of time to recheck the presence of the next coin, and after confirming that there is no next coin, The CPU 41 stops the feeding belt 16 and ends one transaction (steps n12 to n15).

Next, the coin processing operation on the distribution side of the coin processing device will be described with reference to the flowchart of FIG. When the coin inserted into the slot 11 is guided to the discriminating unit 13 and discriminated from the true coin, the coin is guided from the discriminating unit 13 to the internal transfer passage 14 to be discriminated as a defective coin. , And is guided to the return passage 15 (step n21). At this time, in the case of the first sheet, the CPU 41 drives the sorting-side transport belt 20 at high speed to transport it, thereby increasing the sorting processing speed. Further, when discriminating from true coins and deciding the storage at the time of discrimination, the CPU 41 causes the storage units 22 to 25 corresponding to the denominations.
An enable signal to enable the operation is output (step n22).

After that, when the coins guided to the distribution side transport passage 14 are guided to the storage section of the denomination corresponding to the storage enable signal, the distribution side transport belt 20 is driven at a low speed to sort and store the coins. After the speed is set to a low speed suitable for the operation (steps n23 to n26), the coin corresponding to the storage is stored by the sorting guide operation of the sorting guide plate 26 (steps n27 to n29).

After the storage, the sorting-side conveyor belt 20 is driven again at a high speed to increase the sorting processing speed of the coins to be guided next (step n30), and the storing processing is repeated until all the continuously inserted coins are exhausted. Executed (step n3
1).

Incidentally, among the storage sections 22 to 25 provided in the distribution side transfer passage 14, the storage enable signal is not output in the storage section which does not correspond to the denomination, so that the coins are transferred at high speed as they are (step). n32).

As described above, the inserted coins are switched between high-speed transfer and low-speed transfer according to the usage of the discrimination section,
The coin can be transported from the loading slot to the discrimination section at an optimal transport processing speed, and the coins delivered from the discrimination section can be switched between high-speed transportation and low-speed transportation depending on the usage on the sorting side, from the sorting section to the sorting section. Can be transported at an optimal transport processing speed, so that the coin transport processing speed can be increased without impairing the transport processing performance on the coin input side and the sorting side.
As a result, it is possible to reliably reduce the coin deposit processing time.

In the correspondence between the present invention and the configuration of the above-mentioned one embodiment, the feeding side conveying means of the present invention corresponds to the feeding side conveying belt 16 of the embodiment, and hereinafter, similarly, the distributing side conveying means, Corresponding to the sorting-side transport belt 20, the loading-side transport speed control means and the sorting-side transport speed control means are C
