Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to a coin handling device used in public telephones and the like. [Prior art] Generally, 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 insertion detection sensor detects the coins inserted from the coin insertion slot. After that, the material, diameter, and thickness of the inserted coin are inspected by a coin sorting device to determine the authenticity and type of the inserted coin, and if the coin is suitable, the coin sorting device is driven and the coin is transferred to a predetermined storage section. Accumulating coin handling equipment is used. 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 coin sorting device may make an erroneous sorting. Therefore, in order to solve such misjudgments and misallocations, as shown in Japanese Patent Publication No. 57-52634, a timer is started by detecting the insertion of a preceding coin, and within the set time of this timer, A device has been proposed in which, when the insertion of a subsequent coin is detected, the coin sorting mechanism, which is always in the return direction, is kept controlled in the return direction and the preceding and following coins are returned, thereby prompting individual coin insertion. There is. [Problems to be Solved by the Invention] However, with this conventional device, there is no problem as long as the trajectory from the insertion detection sensor or the coin sorting device to the coin sorting device can be long.
When a long orbit is not possible, such as in a desk-top public telephone, there is a drawback that consecutively inserted coins are accumulated in succession based on one determination signal. In other words, the timer setting time mentioned above is
In order to be able to sort the preceding coins and subsequent coins according to their respective judgment signals, the timing of the operation and recovery of the coin sorting mechanism, the mechanical delay time thereof, and the interval between coins that cause erroneous judgments are taken into account. It is determined. Therefore, if the trajectory of the coin is long, even if a subsequent coin is inserted, the preceding coin will not reach the position of the coin sorting mechanism within the timer setting time, so the continuous insertion detection signal will cause the preceding coin to The coin sorting mechanism can be controlled with sufficient time to reach the position of the coin sorting mechanism (for example, the mechanism that was operating on the storage side is restored to the return side), and thereby the preceding coin and the following coin can be returned to prevent erroneous accumulation due to continuous input. However, if the trajectory of the coins cannot be kept long, the preceding coins have already reached the vicinity of the sorting mechanism within the timer setting time, and a signal is generated to restore the sorting mechanism to the return side by detecting continuous insertion. The problem arises that the sorting mechanism is restored while the preceding coins are passing, and that the preceding coins are accumulated or held in the sorting mechanism depending on the timing of continuous insertion detection. On the other hand, if you try to restore the sorting mechanism after confirming the accumulation of preceding coins, there is a problem that subsequent coins will continue to be accumulated due to continuous input, and in any case, erroneous accumulation due to continuous input may occur. The disadvantage is that it cannot be prevented. The present invention was made to solve the above-mentioned drawbacks, and its purpose is to reliably return coins when they are continuously inserted, even if the trajectory to the coin sorting mechanism is not long. It is an object of the present invention to provide a coin processing device that can reliably prevent erroneous accumulation caused by coins. [Means for Solving the Problems] As shown in the functional block diagram of FIG. An overflow linking with the coin sorting device 8 guides the inserted coins to the coin sorting device 5 when the coin sorting device 8 is on the return side, and guides the inserted coins to the return side when the coin sorting device 8 is on the storage side. mechanism 13, a timer 9 which is started when a coin is inserted into the insertion detection sensor 4 and cleared by a genuine coin determination signal, and a timer 9 which is started when the coin is inserted into the insertion detection sensor 4; Sorting device operation permission means 101 for permission for a period of time;
A subsequent coin insertion detection means 102 detects the insertion of a subsequent coin during the operation time of the timer 9, a sorting device stop means 103 stops the operation of the coin sorting device 5 by detecting the insertion of the subsequent coin, and a genuine coin determination signal is detected. Detection sensor operation stop means 104 that stops the operation of the input detection sensor 4 from the time the coin sorting device 8 is restored from the storage side to the return side after the coin is output.
and a control device having. As shown in FIG. 1B, the specific arrangement is such that a coin insertion detection sensor 4, a coin sorting device 5, and an accumulation magnet 6 are installed in order from the upstream side on a coin trajectory 3 leading from a coin input port 1 to an accumulation section 2. A storage lever 8 is arranged, which is driven by the storage lever 8 to the storage side (the side shown by the broken line) and driven to the return side (the side shown by the solid line) by the recovery magnet 7, and is started by the input detection signal from the input detection sensor 4. coin CN
A timer 9 for monitoring the input interval of the input coins, and a control device 10 for controlling the sorting operation of the coin sorting device 5 and the operation of the storage magnet 6 and the recovery magnet 7 according to the sorting results of the input coins and the input state. It is something. In addition, 11 is the return department, 12a,
12b is a return trajectory. [Operation] When the inserted coin is detected by the insertion detection sensor 4, the timer 9 starts, and during this timer operation time, the coin sorting device 5 operates as the sorting device operation permission means 1.
01, the operation is permitted, and if the inserted coin is a genuine coin, a genuine coin determination signal is output from the coin sorting device 5, and the accumulation lever 8, which is a coin sorting device, is driven from the return side to the accumulation side. Subsequently inserted coins during this timer operation time are detected by the subsequent coin insertion operation stopping means 102, and the operation of the coin sorting device 5 is thereby stopped by the action of the sorting device operation stopping means 103, and the accumulation lever 8 is Subsequent coins that return to the return side are returned via the return track 12a. In addition, from the time the coin sorting device 5 outputs the genuine coin determination signal until the storage lever 8 is restored,
The operation of the input detection sensor 4 is stopped by the input detection sensor operation stop means 104. At this time, the accumulation lever 8 is on the accumulation side due to the genuine coin determination signal, but the overflow mechanism 13, which is driven in conjunction with the accumulation lever 8 to the opposite side, is on the return side, so even if the trajectory is Even if coins are continuously inserted for a short period of time, the overflow mechanism 13 ensures that subsequent coins are returned via the return track 12b. [Embodiment] 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 input port 21 and the storage section 22, in order from the coin input port 21, a deposit detection sensor 24, an overflow rail 25, a material sorting coil 26, a dimension detection coil 27, a backflow detection sensor 28, an accumulation Coin guide 29, accumulation lever 30, accumulation detection sensor 31,
An accumulation confirmation sensor 32, a storage lever 33, and a storage detection sensor 34 are arranged. Also, coin trajectory 2
A return track 35 is provided below 3, and is configured such that the inserted coins that are not allowed to be accumulated from the overflow 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, a storage magnet 37 and a recovery magnet 38 are arranged as shown by broken lines. It opens and closes the entrance of the storage track 23a, which is comprised of a track between. The insertion detection sensor 24 detects the insertion of a coin from the coin insertion slot 21, and is composed of a light emitting diode and a light receiving element for optically detecting the insertion of a coin. When the storage lever 30 is driven toward the storage side, the overflow rail 25 is pushed toward the front in the figure by a lever (not shown) about the support shaft 25b, so that the overflow rail 25 is connected to the input detection sensor 24. The coin track 23 is disconnected from the dimension detection coil 27, and the inserted coin is dropped onto the return track 35 and returned to the return section 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, and outputs an output voltage from the receiving coil according to the magnetic permeability of the inserted coin. The output voltage corresponding to the eddy current loss of the inserted coin is extracted from one transmitting coil, and based on these output voltages, iron coins and genuine nickel coins are discriminated. The dimension detection coil 27 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 coil. 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 27 and are once stored are intentionally withdrawn by tilting the phone body or otherwise, and are connected to a light emitting diode. and a light receiving element. When the accumulation lever 30 is driven toward the return side, the accumulation coin guide 29 has its lower end 29b biased toward the front in the figure with the support shaft 29a as a fulcrum by a weight attached to its upper end. , thereby opening the side wall of the coin track between the backflow detection sensor 28 and the accumulation lever 30, allowing the inserted coin to fall into the return track 35 and return it to the return unit 36.
Accumulation lever 30 similar to overflow rail 25
It works in conjunction with. In this case, in this embodiment, only a maximum of three coins can be stored in the storage track 23a between the storage lever 30 and the storage lever 33, so when the fourth genuine coin is inserted, the storage lever 30 is moved. By keeping the accumulation coin guide 29 driven toward the accumulation side and accumulating the fourth genuine coin at this position, the decrease in the number of coins that can be accumulated due to the short coin trajectory 23 is compensated for. . When the input coin is determined to be a genuine coin, the storage lever 30 is driven by the storage magnet 37 in the depth direction in the figure, so that the storage lever 30 moves along the storage track 23a.
When driven to the accumulation side by the accumulation magnet 37, the recovery magnet 38 opens.
The storage side driving state is mechanically maintained until released by . The accumulation detection sensor 31 detects the coins to be accumulated in the accumulation track 23 after the accumulation lever 30 is driven to the accumulation side.
It detects whether the light has entered a, and is composed of a light emitting diode and a light receiving element. The recovery magnet 38 is driven by the detection of coin accumulation 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 the storage lever 33 is driven by the arrival of the charge signal and detects that the accumulated coins are gone. , a tone reminding you to insert coins 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 composed of a light emitting diode and a light receiving element. 3A to 3C are sectional views taken along the line AA in FIG. 2 for explaining the interlocking mechanism of the overflow rail 25, the storage lever 30, and the storage coin guide 29. First, in a standby state before a coin is inserted, the overflow rail 25, accumulation lever 30, and accumulation coin guide 29 are in a state as shown in FIG. 3a. That is, 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 31 is configured to be movable forward and backward on the track 23, and on the opposite side is a lever 31 that comes into contact with the protrusion 25c of the overflow rail 25.
A is provided. On the other hand, two step portions 41a and 41b that are locked to the locking portion 31d of the storage lever 30
The L-shaped locking lever 41 has a long hole 41c at the other end into which a pin 37b protruding downward from the arm 37a of the storage magnet 37 is inserted, and is rotated counterclockwise around the shaft 40 by a spring 42. energized. Therefore, in the coin insertion standby state, the storage magnet 37 and the recovery magnet 38 are in a de-energized state, so the storage lever 30 and the locking lever 41 are biased by the biasing forces of their respective springs, so that the storage lever The locking portion 31d of 30 is locked by the stepped portion 41b of the locking lever 41 to maintain this state. As a result, the tip of the storage lever 30 is connected to the coin track 2.
3, and the overflow rail 25 is pressed against the coin track 23 by a spring (not shown). By pressing the overflow rail 25 against the coin track, the input coin CN can reach the track of the material selection coil 26. Next, if the coin inserted is a genuine coin,
When the storage magnet 37 is energized, the arm 37a rotates counterclockwise, and the locking lever 41 rotates clockwise against the spring 42 due to cooperation between the pin 37b and the elongated hole 41c. As a result, the locking portion 31d of the storage lever 30 is connected to the locking lever 41.
The locking state with the stepped portion 41b is released, the storage lever 30 rotates clockwise, and the locking portion 31d is locked with the step portion 41a as shown in FIG. 3b.
This state is maintained even after the energization of the storage magnet 37 is terminated. 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 coin is guided to the accumulation track, and subsequent coins inserted during this accumulation operation are returned to the return section 36 by the overflow 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 38a of the storage magnet 38, as shown in FIG. 3c. , the locking portion 31d that was locked to the stepped portion 41a changes to the locked state with the stepped portion 41b, and the storage lever 30
is mechanically held in a protruding state in the storage track 23. At the same time, the overflow rail 25 returns to the direction of the coin track 23. Thereafter, when the power supply to the restoration magnet 38 is stopped, the state returns to the state shown in FIG. 3a. 4a and 4b are sectional views taken along line BB in FIG. 2 for explaining the operation of the accumulated coin guide 29,
When the storage lever 30 is driven to the return side, the side wall of the coin track 23 is opened by the weight 29c as shown in FIG. 4a. However, the weight is 29c
A lever 44 is provided to push up the lever 4.
4 is configured to rotate counterclockwise in the figure by a protrusion 43 provided upright on the locking lever 41. Therefore, when the storage magnet 37 is energized, the lever 44 is rotated counterclockwise in the figure by the protrusion 43, and accordingly, the lever 44 exerts a force against the weight 29c, and the storage coins are removed. The guide 29 guides the coin trajectory 2 as shown in FIG. 4b.
3 is closed, and this state is maintained by the locking lever 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 section for processing calls and coins, and roughly divided into telephone circuit section 50;
a control unit 60 that receives charging signals sent from the station side through 0 and controls coin storage, etc.;
Based on the command from 0, the inserted coins are returned and stored in the storage section 22 (Fig. 2), and the coins are returned to the return section 36 (second
The coin processing section 70 returns the coins to The telephone circuit section 50 is connected to the office side through office line terminals L ₁ and L ₂ , and notifies that there is an incoming call via a box switch contact HS ₁ between the line terminals L ₁ and L ₂ . An incoming call display circuit 500, a billing signal receiving circuit 501 that detects billing signals, a diode bridge circuit 502, a power supply circuit 503, a dial pulse sending circuit 504, and a telephone call circuit 505 are connected, and the hook switch contact HS ₁ is connected in conjunction with the off hook. When switched to the side opposite to the side shown, a DC loop including the communication circuit 505 is formed for the office line terminals L ₁ and L ₂ . The diode bridge circuit 502 has a central line terminal
Regardless of the polarity of the DC voltage from the station applied between L ₁ and L ₂ , a DC voltage of constant polarity is supplied to the power supply circuit 503 and the dial pulse sending circuit 504 , and the power supply circuit 503 is A capacitor is charged with the local current from the diode bridge circuit 502 to form a power supply voltage for operation of an arithmetic processing unit (CPU), etc., which will be described later. In this case, the power supply circuit 503 is connected to the office line terminal via the high-low resistor R.
Connected to L ₁ , the built-in capacitor is charged even after on-hook and used as random access memory (RAM).
A backup power supply voltage BUP is generated to protect the memory contents. The dial pulse sending circuit 504 receives the dial pulse signal Di and sends it to the office line.The dial pulse signal Di here is generated by the CPU 600 in response to a signal from the keyboard (not shown).
The signal is input to this dial pulse sending circuit 504 via an input/output interface circuit 603. In this case, while the dial pulse signal Di is being sent, the dial shunt signal DS is given via the input/output interface circuit 603, thereby short-circuiting the telephone call circuit 505 to the caller using the dial pulse signal Di. It is constructed so as not to give rise to pulse noise. Further, this dial pulse sending circuit 504 is configured to be able to forcibly disconnect a call by giving a forced disconnection signal via the input/output interface circuit 603 in the event that there is a shortage of accumulated coins. The control unit 60 includes a CPU 600, a random access memory (RAM) 601, and a read-only memory (ROM) 60 that stores programs and constants necessary for coin processing or telephone call processing.
2. It is equipped with input/output interface circuits 603 and 604 for transmitting and receiving signals with various sensors and the like. Furthermore, a display 605 that displays the accumulated amount of coins and the time of failure, an attitude sensor 606 that detects when the phone body is tilted at a predetermined angle or more,
Equipped with a hook switch contact HS ₂ that opens and closes in conjunction with on-hook and off-hook. The posture sensor 608 is provided to prevent fraud caused 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 the control unit 60, when the charging voltage of the built-in capacitor in the power supply circuit 503 reaches a predetermined value due to off-hook, programs for call processing and coin processing are activated. If a coin is inserted and a dial is operated after the program is started, a dial pulse signal Di and a dial shunt signal Ds are generated, and if a billing signal detection signal is received from the billing signal receiving circuit 501 during a call, which will be described later. A drive signal for storage magnet 706 is generated. Further, when there is a shortage of accumulated coins or when the telephone body is abnormally tilted, a forced call disconnection signal is generated. Next, the coin processing section 70 operates the coin insertion detection sensor 2.
4, etc., a material selection circuit 702 including a material selection coil 26, a thickness selection circuit 703 including a thickness detection coil, a diameter selection circuit 704 including a diameter detection coil, and these selection circuits 702- AD converter (ADC) 70 that selectively converts the analog output signal of 704 into a digital signal.
5. A storage magnet 706, which has a storage magnet 37 and a recovery magnet 38, which together with the storage lever 30 constitute a coin sorting mechanism, and further drives the storage lever 22 (FIG. 2) in response to a billing signal.
have. 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 example,
For example, as a result of reading all input signals to the CPU 600 at a 4ms cycle and determining their contents or status, 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 there is only one task ready flag set, the process corresponding to this flag is executed within the remaining 4ms, and if there are multiple task ready flags set, the process is executed. Select one process with the highest priority among the individual processes such as coin detection processing and display processing that have been disassembled individually and execute it within the remaining time within 4ms, and then execute the remaining processes with lower priority. are executed sequentially on the condition that there is no higher priority processing request in the next new 4ms processing cycle. Therefore, only one of the individually decomposed individual processes such as the coin detection process is executed within the 4 ms processing cycle. Then, when this individual processing is finished, the CPU60
0 is kept in an idle state by an internal reference timer until an interrupt (INT) indicating the arrival of the next processing cycle occurs. 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 order of priority every 4 ms processing cycle, and the processes belonging to the second group are executed for 32 ms. The process is configured to be executed only when there is no request for execution of the process belonging to the first group in each processing cycle. The reason for adopting such a processing system is to reduce power consumption. In other words, inserting coins into public telephones occurs irregularly, so
The responsiveness to this must be set high, but on the other hand, there are processing requests that occur in relatively long cycles, such as processing requests for billing signals. 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 start even though there is no processing request for billing signals. As a result, the CPU is constantly running, resulting in wasted time and increased power consumption. For this reason, in this example, all processes are classified into the first group of processes that need to be executed in a short cycle of 4ms, and the second group of processes that only need to be executed in a relatively long cycle of 32ms. In addition, priorities are set within each group, necessary processing is executed according to this priority, and when the processing is completed, the CPU 600 is placed in an idle state (sleep state) until a new processing cycle arrives, improving responsiveness. At the same time, we aim to reduce power consumption. Note that a CPU with an idle state has the model name HD6301V (manufactured by Hitachi). In this embodiment, the processes executed by the CPU 600 are divided as shown in Table 1 below, and their priorities are determined.

〔Effect of the invention〕

As explained above, the present invention has a timer that is started by detecting the insertion of a coin and is cleared by a genuine coin determination signal, and a coin sorting device that starts by detecting the insertion of a subsequent coin while the timer is operating. a control device for stopping the sorting operation, and when the input of a subsequent coin is detected while the timer is operating, the coin sorting mechanism is left on the return side and both the preceding coin and the subsequent coin are returned; Furthermore, an overflow mechanism is provided that returns subsequent coins in conjunction with the accumulating operating state of the coin sorting mechanism, and while the coin sorting mechanism is driven to the accumulation side by the genuine coin determination signal of the preceding coin, this overflow mechanism is used. This means that only subsequent coins will be returned. Furthermore, the present invention prohibits insertion detection from the time the genuine coin determination signal is output until the recovery signal to the coin sorting mechanism is completed, and subsequent coins are returned by the overflow mechanism or the coin sorting mechanism. It is something. Therefore, even if it is not possible to take a long path to the coin sorting mechanism, when coins are continuously inserted, the coins 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 for the preceding coin is generated, there is no waste in coin processing, and the user side is not burdened with the trouble of having to re-insert coins many times. 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.
