．． F1 from +8! It is determined whether the cargo detection signal has been continuously input for 1 L for a predetermined time (step 52). If it is less than the predetermined time, in step S3, the transport drive time of the transport mechanism 15 by driving the drive motor 26 is determined. It is determined whether the time is less than a predetermined time or not, and if it is less than a predetermined time, the process proceeds to step S4. Therefore, if the presence of the flag is confirmed in step S1, if it is confirmed in step S2 that the coin detection signal has been continuously input for a predetermined number of hours, and if the presence of the drive motor 26 is confirmed in step S3, If it is confirmed that the transport time of the transport mechanism 15 by driving has reached the predetermined time, the process returns to step S1.

In step S4, a predetermined constant is set in the conveyance abnormality detection timer 53 as a permissible time period in which there is no pulse signal from the rotation processor 32, and in step S5, the drive motor 26
is driven in normal rotation to drive the transport mechanism 15 in the transport direction.

Then, in step S6, it is determined whether or not the transport mechanism 15 has been driven for a predetermined period of time based on the state of a predetermined constant set in the transport operation timer 52, and when it is confirmed that the predetermined time has elapsed, step S9 Then, the drive motor 26 is stopped, and the process returns to step S1. When it is confirmed in step S6 that the transport mechanism 15 has been driven within a predetermined time, the state of the sensor abnormality detection timer 56 is determined in step S7; The process proceeds to step S9, and if the predetermined time has elapsed, the process proceeds to step S8 to determine the state of the conveyance abnormality detection timer 53. Then, in step S8, the conveyance U detection timer 5
3 exceeds the predetermined time, the transport mechanism 15
It is determined that a locked state occurs due to a coin jam, etc., and that the coin cannot be transported, and step SI is performed.
The process proceeds to O, and if the predetermined time has elapsed, the process returns to step S6.

In step SIO, the drive motor 26 is stopped, and in step Sll, the reverse operation timer 55 is set to a predetermined value for the drive motor 26 in order to reversely drive the drive motor 26 and release the locked state of the transport mechanism 15 due to coin jamming, etc. Set the reverse drive time.

Then, the C,P U 50 drives the drive motor 26 in the reverse direction in step S], 2, drives the conveying mechanism 15 in the opposite direction by moving the coin by a dimension χ in the coin conveying direction, and at the same time, in step S
When the elapse of the predetermined reverse drive time set in the reverse rotation operation timer 55 in step S11 is confirmed in step S13, the process proceeds to step S13.
At step 14, the reverse drive of the drive motor 26 is stopped, and the transport mechanism 15
stop. By driving the transport mechanism 15 in the reverse direction, the lock state of the transport mechanism 15 can be released. A constant is set, and a predetermined time as a normal rotation driving time of the drive motor 26 is set in the conveyance operation timer 52 in the step S I 6.

This predetermined time is set to a time sufficient to convey the coins received in the coin receiving section 13 to the upper delivery port 16.

Then, in step S17, the CPU 50 drives the drive motor 2B in normal rotation, and in step S18, the transfer operation timer 52 is activated.
Determine whether the predetermined time has elapsed and whether the kotara or sake cup has been set;
If it is determined that the period of time has elapsed, the process proceeds to step S9, and if it has not elapsed, then in step S19, the predetermined period of time has elapsed; judge. If it is determined that the predetermined time has elapsed; -, the process proceeds to step S9; if it is determined that the predetermined time has not elapsed, the process proceeds to step S20, and it is determined whether the predetermined time set in the conveyance abnormality detection timer 53 has elapsed.

When the determination in step S20 determines that the predetermined time has elapsed, the CPU 50 sets a flag as a conveyance abnormality in the conveyance abnormality storage section 54 in step S21, and proceeds to step S9 to stop the drive motor 26. However, if it is determined in step S20 that the predetermined time has elapsed, the process returns to step 818.

That is, when the CPU 50 confirms that the predetermined time set in the transport abnormality detection timer 53 has elapsed in step S20, it is possible to release the locked state of the transport mechanism 15 by reversely driving the drive motor 26 in steps SIO to S14. If the value becomes 0, or if the locked state occurs again and becomes tc, then in step S21, a flag is set and stored in the transport abnormality storage section 54 to indicate the transport abnormality. At this time, the abnormality is displayed on an abnormality indicator (not shown).

Next, the timer interrupt flowchart shown in FIG. 9 will be explained.

In step S22, the CPU 50 determines whether the conveyance drive time set in the conveyance operation timer 52 is less than a predetermined time, and if the predetermined time has elapsed, the CPU 50 executes step S2.
4, and if it is less than the predetermined time, step S23
Then, the predetermined transport drive time set in the transport operation timer 52 is subtracted by 1 to update the time of the transport operation timer 52, and the process advances to step S24.

In step S24, it is determined whether the reverse rotation drive time set in the reverse rotation operation timer 55 has reached a predetermined time,
If the predetermined time has elapsed, proceed to step 526, and if it is less than the predetermined time, proceed to step S25, where the reverse rotation operation timer 55 is set to -1 for the remaining reverse rotation drive time.
Then, the time of the reverse operation timer 55 is updated, and the process proceeds to step S2.
Proceed to step 6.

In step 326, it is determined whether the predetermined time set in the conveyance abnormality detection timer 53 or the set time has elapsed.If the predetermined time has elapsed, the process advances to step S28, and if it is less than the predetermined time, it is determined. In step S27, the time set in the conveyance abnormality detection timer 53 is decremented by 1 to update the time of the conveyance abnormality detection timer 53, and in step S28
Proceed to.

The CPI number 50 detects the detection sensor 17.1 in step S28.
The presence or absence of the coin detection signal from 8 is determined, and when the coin detection signal is input, a predetermined time is set as the forward rotation drive time of the drive motor 26 in the transport operation timer 52 in step S29, and the process advances to step S30. In step S30, it is determined whether or not a predetermined time stored in the sensor abnormality detection timer 56 has elapsed. If the predetermined time has elapsed, the process proceeds to step S33, and if it is less than the predetermined time, step S3] At step S33, the time stored in the sensor abnormality detection timer 56 is updated by subtracting 1 from the time stored in the sensor abnormality detection timer 56, and the process proceeds to step S33.

On the other hand, if the coin detection signals from the detection sensors 17 and 18 are not detected manually in step S28, the CP tJ 50
In step S32, a constant value as a predetermined time is set in the sensor abnormality detection timer 56, and the process proceeds to step S33.

Then, the CPU 50 controls the main body control unit 5 in step S33.
1, and when the coin return command is inputted, a predetermined time is set as the forward rotation drive time of the drive motor 26 in the transport operation timer 52 in step S34, and the process proceeds to step S35, where the coin is returned. If there is no manpower to instruct the return, the process advances from step S33 to step S35.

In step S35, CP (J50 is the rotation sensor 32
After determining the presence or absence of a change in the pulse signal from the stenop S37, in step S36, the transport abnormality detection timer 53 sets the allowable time for allowing no change in the pulse signal to the stenope S37. The process proceeds to step S37, and the change in the pulse signal is confirmed. If the change cannot be confirmed, the process directly proceeds to step S37.

In step S37, it is determined that a conveyance abnormality is recorded in the conveyance abnormality storage unit 54, and it is checked whether the flag is set. If there is a flag, the process proceeds to step S39, and the coin input opening/closing device 32 for opening and closing the coin input opening 4 is activated. Stop operation and coin slot 4
, and prevents the insertion of coins. Proceed to l.

On the other hand, if there is no flag in step S37, it is checked in step S38 whether or not the sensor abnormality detection timer 56 has passed a predetermined time. If it is determined that the predetermined time has elapsed, the coin is near the coin receiving section It is determined that either a blockage has occurred in the detection sensor 1.7 or 1.8, or a failure has occurred in the detection sensors 1.7 and 1.8, or that the dispensing chute 14 has moved away from the receiving position, and the process proceeds to step S39.
The drive solenoid 34 of the slot opening/closing device 32 is turned off to be in a de-energized state, and the shutter member 33 closes the coin slot 4 to prevent coins from being inserted. If the controller abnormality detection timer 56 is less than the predetermined time, step S4
Go to 0.

In step S40, the coin slot opening/closing device 32 is driven to open the coin slot 4, allowing coins to be inserted, and the process proceeds to step 34.1.

The CPU 50 in step S41 checks whether or not a flag is set in the conveyance abnormality storage unit 54, and if the flag is set, in step S43, the CPU 50 sends a U normal signal to the main body control unit 51 and returns the main flow to the main flow. Return. If there is no flag in the conveyance abnormality storage unit 54, step S4
2, it is checked whether the sensor abnormality detection timer 56 has elapsed a predetermined time, and if the predetermined time has elapsed, the process proceeds to step S4.
3, if the time is less than the predetermined time, the abnormal signal specific force to the main body control unit 51 is stopped in step S44,
Return to main flow.

Therefore, the input port opening/closing device 32 is operated during a power outage and when the transport mechanism 1
When the transport mechanism 15 repeatedly stops for a predetermined period of time or more due to the occurrence of a lock state or the like in the detection sensor 17.
18 continues to detect coins for a predetermined period of time or longer, or when the dispensing chute 14 is removed from the receiving position, the coin inlet 4 is closed, and when the electricity is normally on, it is in the driving state and the coin inlet 4 is closed. It's open.

When the customer inserts a predetermined coin from the coin input slot 4, the coin is received into the coin processing device 10 through the input chute 11, and is sorted for authenticity and type by the coin sorting device +OA.

This coin sorting device! OA will select it as a genuine coin.
The coins are stored in the storage section 10B by type. and the coin sorting device unit], the tζ coin determined as a counterfeit coin by the OA, or the coin to be returned based on the return operation, is delivered from the bottom of the coin processing device 10 to the dispensing chute 14,
When the coin is sent to the coin receiving section 13, the detection sensor 17. +8
detects a coin, and the drive motor 26 is driven in normal rotation for a predetermined period of time.

On the other hand, even when the detection sensors 17 and 18 do not detect a coin, the drive motor 26 is driven in normal rotation for a predetermined period of time in response to a coin return command from the control section of the main body. The predetermined time set here is the transport mechanism 1 driven by the normal rotation of the drive motor 26.
The predetermined time is set to be sufficient for the coins in the coin receiving section 13 to be conveyed to the sending port 16 by the normal rotation drive of No. 5.

The transport mechanism 15 is driven to rotate normally by the forward rotation of the drive motor 26, and the packet 24 picks up the coins lying in the coin receiving section 13 and transports them to the upper outlet 16.

If the transport mechanism 15 is locked for a predetermined period of time or more due to a coin jam or the like while the transport mechanism 15 is being driven, the drive motor 26 is driven in the reverse direction for a short predetermined period of time t, and then back again for a predetermined period of time. This protective rolling drive can eliminate obstacles such as coin jams.

Furthermore, if the locked state is generated for a predetermined time or more again during the normal rotation drive, the slot opening/closing device 32 closes the coin slot 4 and prevents the insertion of coins.

On the other hand, if the detection sensors 17 and 18 detect a coin and the state continues for more than a predetermined time, the coin may become clogged near the coin receiving section 13, or the sensor 17.
7.1.8 is in a state where a failure is about to occur, or the dispensing mechanism 1-1 has left the receiving position, and the CPU 50 as a control means controls the transport mechanism 15.
At the same time, the driving solenoid 34 of the slot opening/closing device 32 is turned off to be in a de-energized state, and the coin slot 4 is closed by the puller member 33 to prevent coins from being inserted.

Then, it is transported to the outlet 16 by the transport mechanism 15.
The coins fall from the bucket 24 into the feeder 29 and are guided to the coin return slot 6.

(g) Effects of the Invention Since the present invention is constructed as described above, the position of the coin insertion slot can be set at a height where coins can be easily inserted. Since the coin can be placed in a position where it is easy to take and press the coin, the customer can easily take out the coin without having to bend over much. In this case, the conveyance mechanism can be stopped and the customer can be prevented from inserting coins.
