Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a coin processing device used in public telephones and the like.

[Prior art] In general, in public telephones, etc., an insertion detection sensor, a coin sorting device, and a coin sorting device are sequentially arranged on the coin trajectory from the coin insertion slot, and the coins inserted from the coin insertion slot are detected by the insertion detection sensor. After detecting the coin, the quality, diameter, and thickness of the inserted coin are inspected by a coin sorting device to determine the authenticity and scale of the inserted coin. A coin processing if is used in which the coins are stored in a predetermined storage section.

By the way, in this type of coin processing device, if coins are continuously inserted, the coin sorting device may make an erroneous judgment or the device may make an erroneous sorting of the coins.

Therefore, in order to solve such misjudgment and misallocation, as shown in Japanese Patent Publication No. 57-52634, a timer is started by detecting the insertion of the preceding coin, and the subsequent coin is inserted within the set time of this timer. When detecting the insertion of coins, the IC device proposes that the coin sorting machine, which is normally in the return direction, will continue to control the machine s' in the return direction and return the preceding and following coins to prompt the individual insertion of coins. has been done.

However, with this conventional device, there is no problem in sorting coins from the insertion detection sensor or the coin sorting device if the path to the device is long, but if the path is not long, such as in a desk-top public telephone, there is no problem. This method has a drawback in that consecutively inserted coins are continuously accumulated as they are based on one judgment signal. That is, the setting time of the above-mentioned timer is determined based on the timing of the operation and recovery of the mechanism, the mechanical delay time of these, and the timing of the mechanism's operation and recovery, so that the preceding coins and subsequent coins can be distributed according to their respective determination signals. It is determined by taking into consideration the coin interval that causes false judgments. Therefore, if the trajectory of the coin is long, even if a subsequent coin is inserted, the preceding coin has not yet reached the coin distribution position within the timer setting time, so continuous insertion detection No. 43 will cause the preceding coin to The coin sorting mechanism can be controlled (for example, by restoring the mechanism that was operating on the storage side to the return side) with sufficient outside time before the coin sorting reaches the position of the mechanism, and thereby the preceding coin and the following coin can be returned to prevent erroneous accumulation due to continuous input. However, in cases where the coin trajectory cannot be kept long, the preceding coins have already reached the front of the machine within the timer setting time, and the sorting mechanism returns to the return side when continuous insertion is detected. When the signal is generated, the sorting mechanism will recover while the preceding coin is passing, and depending on the timing of continuous insertion detection,
A problem arises in that the preceding coins are stacked or returned, or the distribution is held in the mechanism. On the other hand, if you try to restore the sorting mechanism after checking the accumulation of preceding coins, there is a problem that the subsequent coins will continue to accumulate because it is in a state of continuous input. It has the disadvantage that it cannot prevent erroneous accumulation due to continuous input.

rObject and structure of the invention] The present invention was made to solve the above-mentioned drawbacks, and its purpose is to sort coins so that even when coins cannot be distributed over a long trajectory to the mechanism, when coins are continuously inserted, To provide a coin processing device that can reliably return coins and reliably prevent erroneous accumulation due to continuous input.

To this end, the present invention, as shown in the basic configuration diagram of FIG. 1, has a coin insertion detection sensor 4. A storage lever 8 is arranged, which is driven by the coin sorting device 5 and the storage magnet 6 to the storage side (the side shown by the broken line), and is driven to the return side (the side shown by the solid line) by the recovery magnet 7. a timer 9 which is started by the insertion detection signal 4 and monitors the interval between coins CN, and a sorting operation of the coin sorting device 5 according to the sorting results of the inserted coins and the insertion state, and the accumulation magnet 6 and the Togaru magnet. A control device 10 is provided to control the operation of the coin sorting device 5, and when the insertion of a subsequent coin is detected during the timer 9's timing operation, the sorting operation of the coin sorting device 5 is electrically inhibited and the accumulation lever 8 is set to the accumulation side. Both the preceding coin and the succeeding coin are returned via a return track 12a branching from the position of the accumulation lever 8 toward the return section 11. On the other hand, an overflow mechanism 13 that operates in conjunction with the storage lever 8 on the upstream side of the coin sorting device 5 and is driven to the return side (the side shown by the broken line) when the storage lever 8 is driven one time to the storage side is installed. If the control device 10 determines whether or not the inserted coin is a proper coin based on the output signal of the coin sorting device 5 and the coin is a proper coin, the accumulation lever 8 is moved to the accumulation side by the genuine coin determination signal at this time. After the operation, the subsequent coins are returned via the return track 1211 by the over 70-iso structure 13 interlocked with the storage lever 8. .

Furthermore, the present invention provides a process from when the genuine coin determination signal of the preceding coin is generated until the recovery magnet 7 returns to the return side due to the drive of the recovery magnet 7 and until the drive signal of the recovery magnet T ends. During this period, the control device 10 prohibits the input detection sensor 4 from detecting the input, so that the subsequent coins are not sorted, and the subsequent coins are returned to the return unit 11 by the overflow machine [13 or the accumulation lever 8]. This is how it was done.

〔Example〕

FIG. 2 is a schematic diagram showing an embodiment of a coin processing mechanism in a public telephone to which the present invention is applied.

In the figure, a two-dot chain line indicated by the symbol 20 represents the external appearance of the side surface of the telephone main body. A coin slot 21 is provided at the upper right side of the figure, and a storage section 22 for storing coins in response to a billing signal from the station is provided at the lower left side of the figure. In the coin track 23 between the coin slot 21 and the storage section 22, insertion detection sensors 24. Overflow rail 25. Material selection coil 269, dimension detection coil 27, backflow detection sensor 8. Accumulation coin guide 29° Accumulation lever 30. Accumulation detection sensor 31. Accumulation confirmation sensor 32. Storage lever 33. A storage detection sensor 34 is arranged. Further, an L return track 35 is provided below the coin track 23, and is configured such that inserted coins that are not allowed to be accumulated from the over 70-rail 25 or the accumulated coin guide 29 are returned to the return section 36. On the other hand, on the back side of the return track 35, there is an accumulated magnet) 37 as shown by the broken line.
and a recovery magnet 38 are arranged, and by driving the accumulation lever 30 in the depth direction and the front direction in the figure,
The entrance of the storage track 23a formed by the track between the storage lever 30 and storage lever 33 is opened and closed.

The insertion detection sensor 24 detects the insertion of a coin from the coin insertion slot 21, and here is constituted by a light emitting diode and a light receiving element that optically detects the insertion of a coin.

When the storage lever 30 is driven to the storage side, the overflow rail 25 is pushed toward the front in the figure with the support shaft 25b as a fulcrum by a lever (not shown). The coin track 23 is disconnected from the detection coil 27, and the inserted coin is dropped onto the return track 35 and returned to the return unit 36.As explained in the basic configuration diagram of FIG.
It works in conjunction with.

The material selection coil 26 detects the material of the inserted coin. Specifically, it consists of a transmitting coil and a receiving coil that are arranged opposite to each other with the coin track 23 in between.The receiving coil outputs a voltage according to the magnetic permeability of the inserted coin. is taken out, and an output voltage corresponding to the eddy current product of the inserted coin is taken out from one transmitting coil, and based on these output voltages, iron coins and genuine nickel coins are discriminated.

The dimension detection coil 2T detects the thickness and diameter of the inserted coin by changes in a high frequency magnetic field formed in the space of the coin orbit 23, and is specifically composed of a thickness detection coil and a diameter detection filter.

The backflow detection sensor 28 detects when coins that have been determined to be genuine coins by the material selection coil 26 and the size detection coil 2T and are once stored are intentionally withdrawn by tilting the telephone body or otherwise withdrawing them. and a light receiving element.

When the accumulation lever 30 is driven to the return side, the accumulation coin guide 29 has its lower end 29b biased toward the front in the figure by a weight attached to the upper end of the accumulation coin guide 29, using the support shafts 29a-f as fulcrums. As a result, the side wall of the coin track between the backflow detection sensor 28 and the accumulation lever 30 is opened, and the inserted coins are dropped onto the return track 35 and returned to the return section 36.
Operates in conjunction with 0.

In this case, in this embodiment, only a maximum of three coins Fi can be stored in the W fil track 23a between the storage lever 30 and the storage lever 33, so when the fourth specie coin is inserted, the storage lever 30 Linked coin accumulation guide 2
9 remains driven to the accumulation side, and the fourth genuine coin is accumulated at this position, thereby compensating for the decrease in the number of coins that can be accumulated due to the short coin trajectory 23.

The storage lever 30 opens the entrance of the storage track 23a by being driven in the depth direction in the figure by the storage magnet 37 when the inserted coin is determined to be a genuine coin. Once driven, the storage side drive state is mechanically maintained until it is released by the recovery magnet 38.

The accumulation detection sensor 31 detects whether coins to be accumulated have entered the accumulation track 23a after the accumulation lever 30 is driven to the accumulation side, and is composed of a light emitting diode and a light receiving element. The restoration magnet 38 is driven by the coin accumulation detection by the accumulation detection sensor 31, and the accumulation lever 30 is restored to the return side.

The accumulation confirmation sensor 32 detects whether or not there are accumulated coins in the accumulation track 23a, and when it detects that there are no accumulated coins due to the storage lever 33 being driven by the arrival of charge number 18, A coin insertion tone is emitted from the receiver.

The storage detection sensor 34 detects whether a coin to be stored is stored in the storage section 22 after the storage lever 33 is driven. Both the storage detection sensor 34 and the accumulation confirmation sensor 32 are constructed of a light emitting diode and a light receiving element.

FIGS. 3(a) to 3(c) show the overflow rail 25. 2 is a sectional view taken along line A-A in FIG. 2 for explaining the interlocking mechanism of the storage lever 30 and the storage coin guide 29.

First, in the standby state before coins are inserted, over 70
- The rail 2s, the '4g lever 30 and the accumulated coin guide 29 are in the state shown in FIG. 3(a). In other words, the storage lever 30 having the locking portion 31d is biased clockwise in the drawing by a spring 31c with the shaft 31b as a fulcrum, and this biasing force and a counterforce force cause the tip of the storage lever 30 to hold a coin. The lever 3 is configured to be able to move forward and backward on the track 23, and on the opposite side is a lever 3 that comes into contact with the protrusion 25c of the overflow rail 25.
1a is provided. On the other hand, the L-shaped locking lever 41, which has two stepped portions 4ia and 41b at one end that locks into the locking portion 31d of the storage lever 30, has a pin protruding downward from the arm 37a of the storage magnet 37 at the other end. 37
It has an elongated hole 41c into which b' is inserted, and is biased counterclockwise about the shaft 40 by a spring 42. Therefore, in the coin insertion standby state, the storage digit magnet 37 and the recovery magnet 38 are de-energized, so that the storage lever 30 and the locking lever 41 are biased by the biasing forces of their respective springs. The locking portion 31d of the lever 30 is connected to the stepped portion 4 of the locking lever 41.
1b to maintain this state. This results in
The tip of the storage lever 30 projects onto the coin track 23, and the overflow rail 25 is pressed against the coin track 23 by a spring (not shown). By pressing the open roll rail 25 against the coin track, the inserted coin CN can reach the track of the material selection coil 26.

Next, when the inserted coin hits a genuine coin and the storage magnet 37 becomes energized, the arm 37a rotates counterclockwise and is locked by the cooperation of the bin 37b and the long hole 41c. The lever 41 is rotated clockwise against the spring 42. Due to this, the locking portion 3id of the storage lever 30 is released from being locked with the stepped portion 41b of the locking lever 41, and the storage lever 30 is rotated clockwise to the position shown in FIG. 3(b). As shown, the locking portion 31dr is connected to the stepped portion 41a.
This state is maintained even after the storage magnet 37 is de-energized. As a result, the storage lever 30 exits the coin track 23 and the overflow rail 25
is separated from the coin track 23 by pushing the protrusion 25c by the lever 31a. As a result, the inserted coins are guided to the accumulation track, and subsequent coins inserted during this accumulation operation are returned to the return section 36 by the flow rail 25.

Next, when the recovery magnet 38 becomes energized after the coin reaches the storage track 23a, the storage lever 30 is pushed in the direction of the coin track 23 by the arm 38aK of the storage magnet 38, as shown in FIG. 3(C). Then, the locking portion 31d that was locked to the step portion 41a changes to a locked state with the step portion 411), and the storage coin <-30 is mechanically held in a state protruding from the coin track 23. At the same time, the overflow rail 25 returns to the direction of the coin track 23. After that, when the power supply to the recovery magnet 38 is stopped, as shown in FIG.
Return to the state shown in a).

FIGS. 4(a) and 4(b) are cross-sectional views taken along line BB in FIG. 2 for explaining the operation of the accumulated coin guide 29, and when the accumulating lever 30 is driven to the return side, the weight 29
c, the side wall of the coin track 23 is opened as shown in FIG. 4(a). However, a lever 44 that pushes up the weight 29C is provided, and this lever 44 pushes up the locking lever 44.
It is configured to rotate counterclockwise in the figure by means of a protrusion 43 erected at 1. Therefore, when the storage magnet 37 is energized, the lever 44 is rotated counterclockwise in the figure by the protrusion 43, and accordingly
4 acts against the weight 29c, and the accumulated coin guide 29 moves along the coin trajectory 2 as shown in FIG. 4(b).
Close the side wall of No. 3, lock this state, and hold by locking <-41. As a result, the inserted coins are guided toward the accumulation lever 30 and finally reach the accumulation track 23a.

In addition, in FIGS. 3 and 4, parts that are not relevant to the explanation of the operation are omitted.

FIG. 5 is a block diagram showing an embodiment of an electric circuit unit that processes calls and coins. Roughly divided into 91, there is a telephone circuit unit 50, and a billing charge sent from the central office side power 1 through this telephone circuit unit 50. A control unit 60 receives a signal and controls storage of coins, etc. Based on commands from the control unit 60, the input coins are sorted and stored in the storage unit 22 (FIG. 2), and the return unit 3
6 (Fig. 2) is composed of a coin handling section TO and a coin processing section TO.

The telephone circuit unit 50 has central office line terminals L1. It is connected to the office side by Lx, and this office line terminal Ll.

Between Lg and Lg, there is an incoming call display circuit 500 for notifying the incoming call via the hook switch contact H8+. ! I! A line signal receiving circuit 501 that outputs a gold signal. Diode bridge circuit 502. Power supply circuit 503. Dial pulse sending circuit 504. When the telephone call circuit 505 is connected and the hook switch contact H8+ is switched to the side opposite to the illustrated side in conjunction with off-hook, a DC loop including the telephone call circuit 505 is formed for the office line terminals Ll and L2.

The diode bridge circuit 502 connects the station line terminal Ll +
Is it the polarity of the DC voltage from the station that is applied between Ij1?
The power supply circuit 503 supplies a DC voltage of constant polarity to the power supply circuit 503 and the dial pulse sending circuit 504, and the power supply circuit 503 charges a capacitor with the local current from the diode bridge circuit 502 and performs the calculation processing described later.
It forms the power supply voltage for operation of the CPU and other devices. In this case, the power supply circuit 503 is connected to the office line terminal L1 via a high resistance R, and is used as a terminal to charge the built-in capacitor and protect the contents of the random access memory (RAM) even after on-hook. Power supply voltage B
UP is occurring.

The dial pulse sending circuit 504 receives the dial pulse signal Di and sends it to the central office line.The dial pulse signal Di here is generated by the CPU 600 in response to a signal from the keyboard (not shown), and is input. This dial pulse sending circuit 5 via the output interface circuit 603
04 is input. In this case, the dial pulse signal Di
During transmission, a dial shunt signal DS is applied via the turnout interface circuit 603, thereby short-circuiting the telephone call circuit 505, so that the dial pulse signal Di does not cause pulse noise to the caller. ing. Further, this dial pulse sending circuit 504 is configured to be able to forcibly disconnect a call by giving a forced disconnection signal via an input/output interface circuit 603 in the event that there is a shortage of accumulated coins.

The control unit 60 is centered around the CPU 600 and sends and receives signals to and from a random access memory (RAM) 601, a read-only memory (ROM) 602 that stores programs and constants necessary for processing coins and phone calls, and various sensors. It is equipped with input/output interface circuits 603 and 604 for performing the following operations.

Furthermore, a display 6 that displays the remaining amount of accumulated coins and in the event of a malfunction is also provided.
05, a posture sensor 606 that detects when the phone main body is tilted by a predetermined angle or more, and a hook switch contact H8++ that opens and closes in conjunction with on-hook and off-hook.

The posture sensor 606 is provided to prevent fraud by tilting the telephone body, and when the telephone body is tilted by a predetermined angle or more, a forced disconnection signal is issued and the call is forcibly disconnected.

In this control section 60, when the charging voltage of the capacitor built into the power supply circuit 503 reaches a predetermined value due to off-hook, a program for processing calls and coins is activated. Then, when the program is started, coin insertion and dial operation cause a slow dial pulse signal Di and a dial shunt signal D6 to be generated, and when the billing signal receiving circuit 501 receives a billing signal detection signal during a call, it will be described later. A drive signal is generated for the housing magnet (706). Furthermore, when there is a shortage of accumulated coins or when the telephone body is abnormally tilted, a forced call cut-off FFr signal is generated.

Next, the one coin processing section 70 includes an optical sensor circuit 701 such as a coin insertion detection sensor 24', a material selection circuit 102 including a material selection coil 26, a thickness selection circuit 703 including a thickness detection coil, and a diameter detection circuit. A diameter selection circuit 704 including a coil, and an AD converter (AD converter) that selectively converts the analog output signals of these selection circuits 702 to 704 into digital signals.
ADC)) 705 has an accumulation magnet 37 and a recovery magnet 3B that constitute a coin sorting mechanism together with the accumulation lever 30, and furthermore, the accumulation lever 22 according to the charge signal.
(Fig. 2).

Next, the operation related to the above configuration will be explained. Note that the operation of the telephone circuit section 50 is not directly related to the gist of the present invention, so a description thereof will be omitted.

First, in the coin processing of this embodiment, for example, 4
As a result of reading all input signals to the CPU 600 at ms intervals and determining their contents or states, if there is a process to be executed, a task ready flag indicating a request to execute that process is set, and then the task ready flag is set. If the status is determined and there is only one task ready flag set, the process corresponding to this flag is executed within the remaining time of 4ms, and if there are multiple task ready flags set, selects one process with the highest priority among the individually disassembled individual processes such as coin detection processing and display processing, executes it within the remaining time within 4 rns, and executes the remaining processes with low priority. next new 4rn
The processing is executed sequentially on the condition that there is no processing request with a higher priority in the processing cycle of s. Therefore,
Within a 4 mB processing cycle, only one of the individually decomposed processes, such as the coin detection process, is executed. Then, when this individual processing is completed, CPTJ60
0 indicates an interrupt (INT) indicating the arrival of the next processing cycle by an internal reference timer, and 1 indicates an idle state.

Here, the priority of each individual process is further classified into the first group and the second group, and the processes belonging to the first group are executed in priority order every 4 ms processing cycle, and the
The processing belonging to the group is configured to be executed every 32m5 processing cycles only when there is no request for execution of the processing belonging to the first group.

This processing system was adopted in order to reduce power consumption. In other words, since coins are inserted irregularly in public telephones, responsiveness to these calls must be set to be high, but on the other hand, coins, such as processing requests for payment signals, occur at relatively long intervals. Also request processing to be done.

Therefore, in such a case, if the clock frequency or processing cycle is determined based on the responsiveness to irregular processing requests, the program may started and CPU
is in constant operation, resulting in wasted time and increased power consumption. For this reason, in this example, all processes were classified into the first group of processes that needed to be executed in a short cycle of 4ms, and the second group of processes that only needed to be executed in a relatively long cycle of 32m5. In addition, priorities are determined within each group, necessary processing is executed according to this priority, and when the process is completed, a new processing cycle arrives, so the CPU 600 is placed in an idle state (sleep state), and responsiveness is improved. Efforts are being made to reduce power consumption. Note that C with an idle state
As for the PU, model name I-H) 6301V (newly manufactured by Hitachi Seisakusho) is [F].

In this embodiment, the processes executed by the CPU 600 are divided as shown in Table 1 below, and their priorities are determined.

Table 1 And since the above processing system is adopted, R
A task ready flag register corresponding to each process is provided in the AM 601 to store the execution request of each process using the memory area, and for example, when the insertion of a coin is detected, it corresponds to the coin detection process. Its execution is requested by setting 111n in the task ready flag register, and it is reset (
Or 0 points.

In addition, the RAM 601 includes a coin data register and a coin flag register that store coin data regarding the material and dimensions of the coin, and a coin flag to indicate whether the coin is a genuine coin or a counterfeit coin. A register is provided for a control timer, such as a coin sorting timer.

Note that the coin sorting timer is realized by a soft timer using the above-mentioned register. This coin sorting timer is shared by the material sorting timer and the dimension detection timer, and when the timer flag is 11, it works as a material sorting timer, and when the timer flag is 2 or 1, it works as a dimension detection timer. .

The operation from inserting coins to accumulating coins will be explained in detail below based on the flowcharts shown in FIGS. 6 to 10.

FIG. 6 is a diagram showing the general flow of processing executed by the CPU 60G, in which the power supply circuit 503
When the charging voltage of the built-in capacitor reaches a predetermined voltage value, the process shown in the general 70- is started. In this general flow, the CPU 60 first connects the input/output interface circuit 603.13 in step 800.
Buffer register in 04 or RAM601
In the next step 801, it is checked whether there is any abnormality in the input detection sensor 24, etc. in the sensor circuit 101.
Furthermore, it is diagnosed whether the storage section 22 is full or not, and if it is possible to make a normal call, the process moves to the next step 802. However, if there is an abnormality in the input detection sensor 24 or the like, or if the beat collecting section 22 is in an abnormal state, a flag indicating this is set, and then the process moves to step 802. . If an abnormal state is detected in the self-bell cutting process in step 801, step 880 (described later) is performed.
In the display process shown in FIG. 7), an abnormality display corresponding to the contents of the flag is displayed on the display 605.

In the process of step 802, the CPU 600
A timer time of 4 ms is set in the first reference timer that defines the processing cycle of the process to be transferred to the group, and the time counting operation is started. Note that this first reference timer is CP
This is built into the U600. After this CPU6
00 detects in step 803 whether or not there is a control timer that is in a timing operation among a plurality of control timers provided for timing, for example, the energization time of the storage magnet 30, and detects whether or not there is a control timer that is in a timing operation. If so, the time value is incremented, and then it is detected whether or not the timer time has expired. If the timer time has expired, for example, a process of stopping the energization of the storage magnet 37 is executed. In this case, from step 802 to step 8091, which will be described later.
The processing time is 4ms defined by the first reference timer.
However, for example, the energization time of the storage magnet 37 is about several hundred m5, so the first frequency division timer returns all green at a cycle eight times 4ms (32m8). Furthermore, the timer time of this first branch timer is divided to have a period of 28 times 32m8 (89
A 20th frequency division timer is provided which repeats the timing operation at a frequency of 6ms), and the timer time of about several hundred m5 is measured using the output of the first frequency division timer, and the timer time of 1 second or more is measured using the second frequency division timer. Time is measured using the output of the branch timer. Note that the control timer and branch timer used in this timer processing may be constituted by a soft timer that utilizes the memory area of the RAM 601, as described above.

Each control timer has its timekeeping function, for example,
- It is not used exclusively for measuring the energization time of the magnet 37, but for example, the program for accumulation/unloading processing described later uses the timer time to be measured and the timer time end conditions for the register corresponding to the desired control timer. By giving the memory address of the program of the process to be executed, it is configured such that it can be used to measure the energization time of the storage magnet 3T or to time the energization time of the recovery magnet 38. There is. That is, the time measurement function of the control timer is selectively defined by the programs for each process shown in Table 1, and after being defined, the time measurement value is updated in the timer process at step 803. In this case, the definition of the timekeeping function is determined by the content of the process to be executed under the condition that the timer time ends.

Thereafter, in step 8040 input sense processing, the CPU 6QO receives all the signals input to the CPU 600, that is, the billing signal receiving circuit 501 and the attitude sensor 60.
6. Hook switch contact H82.

Each output signal of the sensor circuit 701, as well as the output signals of a coin processing function test switch (not shown) and a keyboard dial button (not shown) are detected. Then, C
Based on this detection result, the PU 600 checks whether or not it is necessary to execute individual processing such as coin detection processing in the next ready task check processing at step 805, and determines whether or not it is necessary to execute individual processing. If so, a task ready flag representing the execution request is set in the task flag register corresponding to the required individual process.

Next, in the CPU 600 id step 806, it is checked whether any task ready flags corresponding to each individual process are set according to the priority order shown in Table 1, and if none are set, Proceeding to step 809, the self-operating state is set to the idle state. However, if you check which one of the task ready flags corresponding to each individual process is set, the first detected task ready flag, that is, the task ready with the highest priority among the set task ready flags. The start address of the individual process corresponding to the flag is set in the program counter in the task start process in step 807, and the program of the individual process whose start address is the address set in the program counter in the task execution process in the next step 808 is executed. One of the processes shown in steps 810 to 900 in FIG. 7 is executed. When this individual processing is completed, the self is set to an idle state in step 809, and the 4m
If an interrupt indicating that the timer time s has expired and a new processing cycle has arrived is generated from the first reference timer, the process returns to step 802 and the same process is repeated thereafter. In this case, the task ready flag of the individual process that has been executed is reset at the stage when the start address is set in the program counter. Therefore, in the next new processing cycle, the next priority j[-ranked individual processing will be executed.

However, for the task ready flag requesting execution of an individual process belonging to the second group, the CPU 600 executes 32r in the ready task check process in step 805.
The timer time of the second reference timer of ns has expired, and the first
The set state is detected on the condition that all the task ready flags of the group are not set. And C
Regarding the second reference timer of 32m5 that defines the processing cycle of individual processing belonging to the M2 group, the PU 600 determines in the ready task check processing in step 805 that there is no processing request for the "th group" or has disappeared immediately after off-hook. After that, the timer value is updated each time step 805 is passed, and as a result of the update, when the timer time expires, the process is restarted on the condition that there is no execution request for the individual processing belonging to the first group.

Therefore, immediately after off-hook, the individual processing belonging to the second group is given the opportunity to execute for the first time after 32m5 has passed since the first group no longer has a processing request, and after that, if there is no processing request from the first group, 32m5
You will be given an opportunity to perform each step.

In this way, all processes related to call processing and coin processing are broken down individually, and are processed every 4ms or 32m depending on the priority seat order.
The CPU 500 is executed every 5 cycles, and the CPU 500 is placed in an idle state immediately after the execution is completed.

Therefore, by assigning the processing to be performed when coin insertion is detected to the first group, which has a high priority, the response to this process will not be lost and power consumption can be reduced.

Next, each step shown in steps 810 to 900 in FIG. 7 is not directly related to the gist of the present invention, so a description thereof will be omitted.

a1 Normal Operation First, the normal operation when the inserted coins are genuine coins and are inserted at fixed time intervals will be explained using detailed flowcharts shown in FIGS. 8 to 10.

Usually, the coin detection process shown in FIG. 8 is executed first.

This coin detection processing has the highest priority over other processing requests when the insertion of a coin is detected by the coin insertion detection sensor 24 and a task ready flag indicating a request to execute the coin detection processing based on this insertion detection is set. and executed.

In this coin detection process, the CPU 600 first checks in step 8100 whether or not the coin sorting timer is on, that is, whether or not it is in a timing operation. As a result, Hikokere is Stella 7" 8101 during the timekeeping operation.
At this point, the coin data register and the coin flag register are reset, and then the power to the thickness sorting circuit 703 and diameter sorting circuit 1 port 4, which constitute the coin sorting circuit, is turned on. That is, in this embodiment, in order to reduce power consumption, the operating power of the thickness sorting circuit 703 and the diameter sorting circuit 704 is cut off in the standby state for coin insertion. For this reason, when the coin sorting timer is not in a timing operation and insertion detection occurs, the CPU 600 turns on power to these circuits 703 and 704, making it possible to detect the thickness and diameter. Note that the light emitting diode constituting the coin insertion detection sensor 24 is also dynamically illuminated at a 4 ms cycle for the same purpose. However, the power for operating the material selection circuit 702 is always turned on. In this case, circuits 703 and 704
The power is turned on and off via the input/output interface circuit 604, and the time when the power is turned on is determined when the timer flag of the coin sorting timer is "1" or [21], and the coin sorting timer is the material sorting timer or the size sorting timer. It is only for a certain period of time while working as a timer. Normally, the coin sorting timer first works as a material sorting timer and then continuously as a dimension detection timer. The operating power is turned on for a certain period of time.

Therefore, when the insertion of a coin is detected by the coin insertion detection sensor 24, unless the coin sorting timer is in a timing operation, the power to the thickness detection circuit 703 and the diameter detection circuit 704 is turned on for a certain period of time, thereby detecting the insertion of the inserted coin. Along with material selection, coin dimensions such as thickness and diameter can be detected.

The CPU 600 operates the circuits 703 and 70 as described above.
4, a predetermined time is set in the coin sorting timer in step 8103, and then the timer 75f (TMFLG) f is turned on in step 8104.
: rlj) Then, the function of the timer for each hard lever 1 is defined as a material selection timer, and the process returns to the general 70- shown in FIG. When the function of the coin sorting timer is defined as a material sorting timer, the material sorting timer entrusts its timekeeping operation and management of the timer time end to the timer processing in step 803.

In this way, the thickness selection circuit γ03 and the diameter selection circuit 1
When the material sorting timer starts measuring operation following the power-on of the "6704," in the ready task check process of step 805 in the next new 4.ms processing cycle, the CPU 600 causes the coin sorting timer to operate as the material sorting timer. It is detected that the coin data input process is executed, and a task ready flag indicating a request to execute the coin data input process is set, and in the subsequent task execution process of step 80B, the coin data input process shown in detail in FIG. 9 is executed.

In this coin data input process, after inputting data regarding the material of the inserted coin from the material sorting circuit 702, if the material is appropriate, the function of the coin sorting timer is redefined as a dimension detection timer, and the thickness sorting circuit 703 and the diameter selection circuit γo4 also input data regarding the thickness and diameter of the inserted coin.

In the coin data input process of FIG. 9, the CPU 600 sets the timer flag (TMFL
After confirming that G) is “1-1,”
The input mode of the converter 705 is set to the iron coin material B mode, and the output signals from the receiving coil for material selection provided in the material selection circuit 702 are selected as input to the AD converter 7050. In step 8202 , the output signal from the receiving coil is sampled at predetermined time intervals, converted to digital data, and taken in via the input/output interface circuit 604 . Next, step 82o3
Then, the input mode f of the AD converter 705 is set to the Tsugaru coin material selection mode, and the output signal from the material selection transmitting coil is selected as the input to the AD converter γ05. The output signal from the receiving coil is sampled, converted into digital data, and processed via the input/output interface circuit 604. Thereafter, by comparing the data regarding the material of the inserted coin obtained in this manner with a predetermined value, it is determined in step 82o5 whether or not the inserted coin is made of an appropriate material. Step 8
206, the timer flag (TMFLG) is set to “2-I
By doing so, the coin sorting timer is redefined as a dimension detection timer, and in the following step 82o7, a predetermined time is set in this dimension detection timer to start a timing operation. After this tv, the CPU 600 returns to the general flow process shown in FIG.
It remains in an idle state until the next processing cycle arrives.

After that, when a new processing cycle of 4 ma determined by the first reference timer arrives, steps 802 to 804
Following the process, the ready task check process in step 805 is executed, but since the coin sorting timer is operating as a dimension detection timer at this time, the task ready flag is set again to request execution of the coin data input process. 1
, in the subsequent task execution process (step 808), the coin data input processing FI! Execute. Then, the timer flag (T]', /IFLG) becomes "2-1".
Therefore, the CPU 600 executes step 8200.
After the judgment process in step 8208, the process in step 8209 and subsequent steps is executed to check whether the thickness and diameter of the inserted coin are appropriate.

Therefore, first in step 8209, the CPU 600 sets the input mode of the AD converter 705 to the thickness screening mode, selects the output signal from the thickness screening circuit 703 as the input to the AD converter 705, and then performs the next step 8210.
Then, the output signal of the circuit 703 is sampled at predetermined time intervals, converted into digital data, and captured while extracting a peak value that appears depending on the thickness, and temporarily storing the peak value. Next, in step 8211, AD
setting the input mode of the converter 705 to diameter sorting mode;
The output signal from the diameter selection circuit 704 is sent to the AD converter 705.
In the next step 8212, the four output signals of the circuit 704 are sampled at predetermined time intervals, converted to digital data, and captured while extracting the peak value that appears depending on the diameter. Remember.

After this, it is determined in step 8213 whether the inserted coin has the appropriate thickness and diameter based on the data regarding the thickness and diameter of the inserted coin obtained in this way, and it is determined whether the inserted coin has the appropriate thickness and diameter. If it's the correct currency, step 8
After setting a coin flag representing the type of coin in the determination process of step 214, a process for accumulating the coin in the accumulation track 23a is performed in steps 8215 and thereafter.

That is, if the inserted coin is a proper coin, the CPU 600 turns on all the coin sorting timers that were currently functioning as dimension detection timers in step 8215, and then turns on the power source of the coin sorting circuit, that is, the thickness sorting circuit γ03 and After cutting off the power to the diameter selection circuit 704, in the next step 8217, a drive signal is sent to the storage magnet 37, and this magnet 3T
Turn on. After this, in step 8218, it is checked whether the accumulated number of coins in the coin trajectory 23a has already reached 3, and if it is less than 3, step 8
In step 219, the accumulation detection operation by the accumulation detection sensor 31 is permitted. That is, if the number of accumulated coins is less than three, the light emitting diode constituting the accumulation detection sensor 31 is dynamically illuminated at predetermined time intervals, and the inserted coins entering the coin track 23a are detected through the accumulation lever 30 driven to the accumulation side. Make it possible. After this, the CPU 600 prohibits loading and unloading of coins in step 8220.

That is, the dynamic lighting of the light emitting diode of the coin insertion detection sensor 24 is stopped, and insertion detection is not performed until the accumulation operation of the inserted coins currently being accumulated is completely completed. The newly inserted coins are dropped onto the return track 35 from the overflow rail 25 which is driven toward the return side.

When the above process is completed, the CPU 6013 returns to the general flow process shown in FIG. 6, but since the storage lever 30 is driven to the storage side by driving the storage magnet 3T, the inserted coins will be removed after a certain period of time has passed. Accumulation trajectory 2
3a, and an accumulation detection signal is generated from the accumulation detection sensor 31 accordingly. This accumulation detection signal is 4rns
Input sense processing for a new processing cycle (step 80
4) is detected by the CPU 600. Then, the CPU 600 sets the task RESOLUTION flag indicating a request to execute the accumulation detection process, and executes the accumulation detection process shown in detail in FIG. 10 in the subsequent task execution process (step 808). In the detection process, the CPU 6001
In jtf step 8300, the amount of inserted coins is calculated based on the coin flag representing the type of inserted coin obtained by the above-mentioned coin data input process, and this amount of inserted coins is stored in the memory area corresponding to the storage rank in the storage type memory. Store.

After this, in the credit addition process of step 8301, the unused amount of coins stored in the storage unit 22 as a call fee is added to the accumulation order stored in the accumulation order memory, and the amount of coins stored in the storage unit 22 is added to Calculate the coin amount. In this case, a task ready flag is set to display the amount of coins that can be called on the display 605 in the display process (step 880 in FIG. 7), and then the display 605 is set when the display process is executed. will be displayed in numbers.

Next, since it is no longer necessary to perform accumulation detection, the CPU 600 detects the accumulation detection sensor 31 in step 8302.
Dynamic lighting of the light emitting diodes is stopped, and accumulation detection 91] is prohibited. After that, in step 8303, it is determined whether or not the number of accumulated images is 4. If 4 images are not displayed, the accumulation magnet 37 is
The next step 83 is performed after the transmission of drive signals to the target has completely stopped and a predetermined interval time (for example, 32 m5) has elapsed.
At step 05, a drive signal to the old magnet 38 is sent out for a certain period of time. When the time for sending the drive signal to the recovery magnet 38 ends, the coin insertion detection, which has been prohibited since step 8220 in FIG. 9, is returned to the permitted state in step 8306.

As a result, the accumulation lever 30 and the input detection sensor 24
returns to the same state as before the coin was inserted.

Note that the sending time of the drive signal to the recovery magnet 38 is controlled using the aforementioned control timer, and the timer time of this control timer is determined by the amount of time the storage lever 30 is switched to the return side after the recovery magnet 38 is turned on. From the time at
It has been set for a long time. Therefore, the insertion detection, which has been prohibited from the time when the drive signal Ig of the storage magnet 3T is generated, is performed after a certain waiting time has elapsed after the storage lever 30 is switched to the return side. However, even if the next coin is inserted immediately after the M stacking bar 30 is moved, the insertion detection will not be performed and size sorting will not be performed. The coins inserted at the time will be restored to the return side and will be returned by the accumulated coin (□-30).

On the other hand, for the storage magnet 37. The drive time is also controlled using the aforementioned control timer, and the timer time is set to be longer than the time from when the accumulation lever 30 is turned on until the inserted coin reaches the orbit of the accumulation detection sensor 31. Teroru. Therefore, in practice, accumulation is almost always detected before the timer expires.
In such cases, priority is given to accumulation detection (accumulation magnets).
Sending of the drive signal to 37 is stopped in step 8304. At the same time, since there is no need to manage the sending time of the drive signal to the storage magnet 37, the control timer for managing the drive time is reset in step 8304 and its mission is canceled.

By the way, in this embodiment, in order to compensate for the short coin trajectory, when the next coin is inserted when the number of accumulated coins is already 3, the accumulated coin guide 29 is set to the accumulation side and set to 1\. , the fourth coin is accumulated on the orbit of this accumulation coin guide 29.

In such a case, the accumulation detection sensor 31 cannot perform accumulation detection in order to store the third accumulated coin. Therefore, in step 8221 of FIG. 9, the CPU 600 u waits for the timer time of the control timer that manages the drive time of the storage magnet 37 to end, and immediately after the timer time ends, sets a task ready flag indicating a request to execute the grass pile detection process. At the same time, the sending of the drive signal to the storage magnet 37 is stopped, and thereafter the execution of the storage detection process shown in FIG. 10 is started. Then, step 830 of this accumulation detection process
In step 830T, it is determined that the accumulated number of coins has become 4 based on the contents of the accumulation order memory, and in step 830T, insertion detection is prohibited, while newly inserted coins are detected by the accumulation lever 30.
The vehicle is returned to the return track 35 via the overflow rail 25 which is driven to the return side in conjunction with the above. Furthermore, at this time, the accumulation lever 30 is removed while being mechanically held on the accumulation side, so if the phone body is intentionally tilted, the accumulated coins will automatically flow through the flow rail 25 and return to the return track 35. It is conceivable that the product may fall and lead to fraudulent activity. Therefore, backflow detection by the backflow detection sensor 28 is permitted in the CPU 600 U step 830B. If the backflow of coins is detected by this backflow detection sensor 28, and if an output signal from the ruruike attitude sensor 606 is generated, a task ready flag indicating a request to execute the hook process shown in step 890 in FIG. 7 is set. death,
By executing this hook process, a forced disconnection signal is generated in the call circuit 505, and the call is forcibly disconnected.

b. Operation when a coin with poor material is inserted When a coin with poor material is inserted fc, after the CPU 600 detects the insertion, the CPU 600 executes the coin detection process 'f: shown in FIG. 8.
The coin data input process shown in FIG. 9 is executed, but since the material is defective, the process returns immediately from step 8205 to the general throw process shown in FIG. 6.

For this reason, the timer flag (TMFLG) of the coin sorting timer
) is not updated to ``2-1'' and its timer time is not reset.As a result, the power to the thickness sorting circuit 703 and diameter sorting circuit 704 is turned off so that the coin sorting timer ends its time as the material sorting timer. Therefore, the storage lever 30 is not driven in any way.
Inserted coins with poor material hit the storage lever 3o that is in the return drive state and are transferred to the return track 3 via the coin storage guide 29.

FIG. 14 is a time chart when coins with poor quality are inserted.

C9 When a coin with defective dimensions is input, the material is appropriate, but if a coin with an inappropriate thickness or diameter is input, the CPU 600 selects the material, and after the sorting process, performs steps 82o9 onward in FIG. The process is executed, but since either the thickness or the diameter is inappropriate, the process immediately returns to the general flow shown in FIG. 6 from step 8214. For this reason, the storage lever 3oI-i is not driven in any way, and the inserted coins with a defective thickness or diameter hit the storage lever 3o, fall into the return track 35 via the coin storage guide 29, and are returned to the return section 36. be done.

d. Operation when coins are continuously inserted. As a mode of continuous coin insertion, the timer of the coin sorting timer that starts operation by the insertion of the prisoner's preceding coin is the case in which a subsequent coin is inserted before r#IJ ends, ω) Advance. In the case where a subsequent coin is inserted after the coin genuineness determination signal is generated until the storage lever 30 returns to the return side, (0) the drive time of the recovery magnet 3B after the storage lever 30 marks the return side. There are three types of cases in which subsequent coins are inserted until the end of the coin.
Tz.

There are three ways in which subsequent coins are inserted in each period of T3.

Among these cases, in case g3), since the overflow rail 25 is driven to the return side in conjunction with the accumulation lever 30, the subsequent coins are returned to the return unit 36 by the overflow rail 25. Also, overflow rail 25
Even if a subsequent coin is inserted near the boundary of the timing when returns to the storage side and passes through the orbit of the material sorting coil 26, the storage lever 30 is not driven to the storage side because insertion detection is not performed at this time. The coins are returned to the return unit 36 via the coin accumulation guide 29. In case <C), the item is returned to the return unit 36 for the same reason.

On the other hand, in case (■), the thickness sorting circuit 703 and the diameter sorting circuit 70 are used in the coin detection process shown in FIG.
4's power supply 'ff: By cutting off, the subsequent coins are transferred to the return section 36 along with the preceding coins via the coin accumulation guide 29.
will be returned to.

That is, if a subsequent coin is inserted during the coin sorting operation due to the insertion of a preceding coin, the CPU 600 selects the subsequent coin.
When coins are detected, the coin detection process shown in FIG. 8 is executed, but since the coin sorting timer is in operation, the process moves from step 8100 to step 8105, where coins are continuously inserted into the coin flag register. Sets the continuous input error flag to indicate that the

After this, in the next step 8106, the timer flag (
Check the contents of TMFLG) and confirm that the contents are ``
If it is not 0-1, the power to the thickness sorting circuit 703 and diameter sorting circuit 704 is cut off in the next step 8107, and if it is "O", a coin sorting timer is set in step 8108. That is, if the coin sorting timer is operating as a material sorting timer or a dimension detection timer, the timer flag (TMFLG) is "1" or r21. Therefore, if a subsequent coin is inserted in this state, the CPU60G
In step 8107, the power to circuit 703 and circuit 704 constituting the coin sorting circuit is cut off. After this,
The timer time is reset to the coin sorting timer and the time counting operation is started. Then, in the next step 8109, the timer flag (TMFLGl) is set to 01, and in the subsequent step 8110, the input detection sensor 24 prohibits the input detection.In other words, the CPU 600 activates the coin sorting circuit by continuously inputting the second coin. The coin sorting timer is restarted from its initial value, and insertion detection is prohibited.

Furthermore, a timer flag (TMFILG) is set to indicate that the coin sorting timer is operating due to continuous input.
Let be ``01.''

As a result, coin sorting of both the preceding coin and the following coin becomes impossible, and both coins hit the accumulation lever 30 which changes to the return drive state and are returned to the return section 36 via the coin accumulation guide 29.

Thereafter, when the timer time of the coin sorting timer operating with the timer flag "OJ" ends, the timer end process shown in FIG. 11 is selected and executed in the timer process in the general flow of FIG. 6.

In this timer end processing in FIG. 11, the CPU 60
0 checks in step 8120 whether or not the input detection is in the permitted state. When the second coin is continuously inserted, since insertion detection is already prohibited in step 8110 of FIG. 8, the CPU 600 selects the coin selection timer 8121d and resets the timer time in the coin sorting timer. Then, in step 8122, the timer ready flag is also set to 1'', and in the next step 8123, the prohibition of input detection is canceled.The timer ready flag is set to 11'' because the timer in FIG. This is done to update the coin sorting timer's clock value during processing.

That is, here, the coin sorting timer that was restarted by the continuous insertion of the second coin is restarted a third time, and the inhibition of insertion detection is canceled. by this,
It becomes possible to detect the insertion of the third coin. After that, when the timer time of the coin sorting timer that was started three times expires, the timer flag (TMFLG) remains rO.
Since J is output, the timer end process shown in FIG. 11 is selected.

Then, at this time, the input detection is stuck in the permission state, so C
The PU 600 selects the process in step 8124 based on the determination in step 812o, sets the timer ready flag to qOu, and returns to the process in the general flow of FIG. 6.

This completes a series of processes for preventing continuous coin insertion.

Here, the coin sorting timer is set to step 8121 in FIG.
When the third coin is inserted following the second coin while the timing is started three times and the timing operation is being executed by the process of The coin detection process shown in the figure is executed, and steps 8105~
The process of 811o is executed again. In other words, if a third coin is inserted after the second coin, the process returns to the same state as when the second coin is inserted after the first coin, and the third coin is inserted. The coins are also returned to the return unit 36.

As a result, the continuously inserted coins are returned one after another.

Furthermore, in this embodiment, both the preceding coin and the succeeding coin that have been inserted can be returned to the return unit 36 after the timing of canceling the inhibition of insertion detection.

That is, when a second coin is inserted after the first coin, the coin sorting operation is electrically inhibited and the coin sorting timer is restarted, and the subsequent coins whose coin sorting timer is restarting are Since coins are inevitably inserted continuously, insertion detection is prohibited to save power consumption, but if the prohibition of insertion detection is simply canceled after the restarted coin sorting timer expires, insertion detection will be disabled. In the 1F state, it is unknown whether a coin has been inserted or not, so if the third coin is inserted while the insertion detection is prohibited, and the fourth coin is inserted after the insertion detection prohibition is canceled. If this is the case, these third and fourth coins are considered to be continuous input coins, but the fourth coin is judged to be an individual input. A $ situation occurs in which the preceding third coin is also accumulated continuously.

However, as mentioned above, the coin sorting timer is restarted only once even after the inhibition of insertion detection is lifted, so the coins inserted when the inhibition of insertion detection is disabled do not accumulate, and both coins are continuously inserted. It can be returned as. That is, even if the insertion detection prohibition operation is performed, the continuous insertion monitoring function can be maintained by restarting the coin sorting timer only once.

Furthermore, if no coin is inserted before the operation of the coin sorting timer restarted after the insertion detection prohibition is canceled, the system returns to the initial coin insertion waiting state, and after that, the individual inserted coins are detected normally. Ru.

Fig. 16 is a time chart when coins are continuously inserted, and Fig. 16 (a) shows the operating time of the coin sorting timer;
(b) shows the processing contents of the CPU 600, where Xl shows the coin detection process and X2 shows the size selection process. (c) is the power supply time to the thickness selection circuit 703 and the diameter selection circuit 704, and (d) is the power supply time to the input detection sensor. 24 operating hours. Moreover, the diagonally shaded section in FIG. 3A indicates that the coin sorting timer is restarted by canceling the insertion detection prohibition. Furthermore, to represents the insertion detection timing of the second coin, and arrow A indicates the timing at which the input detection timing is restarted by canceling the insertion detection prohibition. It represents a return to normal condition.

〔Effect of the invention〕

As explained above, the present invention includes a timer that is started when a coin is detected and cleared by a genuine coin determination signal, and a control that completely stops the sorting operation of the coin sorting device when a subsequent coin is detected while the timer is operating. A device is provided, and when the insertion of a subsequent coin is detected while the timer is operating, the coin distribution mechanism is set to the return side/ζ1X so that both the preceding coin and the subsequent coin are returned, and furthermore, the coin distribution is An overflow mechanism is provided to return subsequent coins in conjunction with the accumulating operating state of the mechanism, and while the mechanism is driven to the accumulating side, coins are distributed according to the genuine coin determination signal of the preceding coin, and subsequent coins are returned by this overflow mechanism. It is designed so that only the following items are returned.

Furthermore, the present invention prohibits insertion detection from the output of the genuine coin determination signal until the completion of the recovery signal to the coin sorting mechanism, and allows subsequent coins to be returned by the overflow mechanism or by the coin sorting mechanism. The one I made is Ruru.

Therefore, even when coin sorting cannot take a long path to the mechanism, when coins are continuously inserted, they can be returned reliably, and erroneous accumulation due to continuous insertion can be reliably prevented. In addition, since only the preceding coins are accumulated after the genuineness determination signal of the preceding coin is generated, there is no waste in coin processing, and the user side does not have to worry about the trouble of having to re-insert coins even if they go bankrupt. This reduces the number of operations required, which is also beneficial in terms of processing efficiency and operability. Therefore, when applied to devices such as desk-top public telephones, extremely beneficial effects can be achieved.

An overflow mechanism is provided on the downstream side of the coin sorter, and the coin sorting is performed by an overflow mechanism that returns subsequently inserted coins in conjunction with the accumulating operating state of the device, and an overflow mechanism that returns subsequently inserted coins in conjunction with the accumulation operation state of the device, and a misstart mechanism that returns the coins that have been inserted subsequently by the insertion detection sensor. The operation of the coin sorting device is permitted during the timer time of the timer based on the timer that is cleared and the insertion of a coin is detected by the input detection sensor, and the operation of the coin sorting device is enabled by detecting the insertion of a subsequent coin during the timer time. and a control device that stops the operation of the input detection sensor from when the genuine coin determination signal is output until the coin distribution operation recovery signal for the coin distribution device is terminated. , K was added to prevent continuous coin insertion.
