Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a coin insertion device in a coin insertion operating device such as a game machine or a vending machine.A conventional coin insertion device will be described with reference to FIG. FIG. 1 illustrates how an inserted coin 3 presses down an actuator 2 of a microswitch 1 provided in a coin insertion device in a conventional device. First, the coin 3 inserted into the coin insertion slot (not shown) moves inside the coin guiding member (not shown) (FIG. 1(a)), and pushes down the actuator 2 (FIG. 1(b)). When the actuator 2 is pushed down to a certain position by the coin 3, the microswitch 1 is operated and a signal indicating that the coin has been accepted is emitted from the terminal 4. As the coin 3 moves further, the actuator 2 finally leaves the coin 3 (FIG. 1(C)) and returns to its original position to prepare for insertion of the next coin (FIG. 1(D)).

Since conventional devices have the above-described configuration, customers often commit fraudulent acts.

A typical method is to tie a fishing line or the like to the coin to be inserted in advance, insert the coin through the coin insertion slot, operate a microswitch, and then pull up the coin with the string.

However, the conventional device shown in Figure 1 is configured to determine that the coin has been accepted by detecting that the actuator is pushed down by the inserted coin, so it detects the coin being pulled up by a fishing line or the like and detects fraud. It is difficult to determine that an action is being taken.

Also, by using three 7-way sensors, the inserted coin should be moving within the coin guide member in a time within the allowable range (moving within the coin guide member at a speed within the allowable range). There is a device that detects and prevents the above-mentioned fraud, but this device uses three photosensors, which is expensive (and generally prevents coins from entering the coin-conducting member). It does not detect movement in the opposite direction (the coinka bow being lifted up by a fishing line, etc.).

The m aspects of fraudulent acts by customers are as follows:
There are coins with different numbers, coins with holes, etc. that are inserted, but it is difficult to detect these fraudulent acts using the conventional devices described above.

The present invention has been made in view of the above-mentioned shortcomings of the prior art, and there is a possibility that an inserted coin may be pulled up by a fishing line or the like within the coin guide member due to fraudulent acts, or a coin of a different diameter or a coin with a hole may be inserted. It is an object of the present invention to provide a coin insertion device that can detect when a coin has been inserted and can be constructed at low cost.

In order to achieve the above object, the present invention provides a conventional coin insertion device with two 7-photo sensors for detecting passage of a coin, and the time required for a coin to move within a coin guiding member based on signals from a photosensor. A timer to measure the coin movement, a device to detect that the coin is moving in the opposite direction to the coin movement direction under normal conditions, and a device to detect that the diameter of the coin is not within the specified range. Based on these signals, it is determined whether a coin of a predetermined thickness is moving in a predetermined direction at a speed within an allowable range. The present invention provides a coin insertion device equipped with a determination processing circuit that prevents an insertion type actuator from performing a desired operation.

The present invention will be described in detail with reference to FIGS. 2 to 7. FIG. 2 is a circuit diagram of one embodiment.

A coin guide member 6 that guides coins moving in the direction of the arrow 5 (the coins are sorted in advance by a coin selector, etc.) has two sets of slits 7a spaced apart from each other by the diameter of the coin in the direction of movement of the coin. 7b, and two light sources 8a are provided at both ends thereof.

Photo sensors 8b and 21 are provided with photosensors 9a and 9be.

The light emitted from the light sources 8a and 8b passes through the slit 7a, respectively.
, 7bY and two photosensors 9a.

9b.Here, the photo sensor 9a,
It is assumed that each of 9b is constituted by a phototransistor, which turns on when irradiated with light and turns OFF when no light is irradiated.

The output of the photosensor 9a is applied to an AND circuit G0, an OR circuit G3 and a reverse movement detector 10, and the output of the photosensor 9b is applied to an AND circuit G2. applied to OR circuit G3 and reverse movement detector 10. Here, the reverse movement detector 10
is composed of flip-frogs, diodes, etc.
Photo sensor 9a.

The output is inverted by the signal from 9b. Further, the output of the OR circuit G3 is given to an AND circuit G4.

The clock pulses CLK generated from the oscillator 11 are respectively applied to AND circuits G1. G, , G4 to binary counters 12, 13, 14, where the clock pulses CLK are counted. Then, each count value is given to the determination processing circuit 15.

The determination processing circuit 15 determines whether or not a fraudulent act is being committed based on these count values, and when it is determined that a fraudulent act is being committed, it issues a signal from the terminal 16 to cause the coin insertion actuation device (not shown) to perform the desired operation. Do not allow any movement. Note that the determination processing circuit 15 includes binary counters 12 , 13 ,
Immediately after receiving the count value from the terminal 14, a pulse is generated from the terminal 17, and this pulse is applied to the AND circuit 05. At this point, since the output of the reverse movement detector 10 is given to the AND circuit G5, it is possible to determine whether the coin is moving in the opposite direction (a fraudulent act) based on the output of the AND circuit G5. 7 Next, the operation of the embodiment shown in FIG. 2 will be explained with reference to FIG. 3. Note that FIG. 3(a) shows the case when the predetermined coin is correctly inserted, and FIG. 3(b) does not show the case when the predetermined coin is moved in the opposite direction.

Before time t1, the inserted coin has not yet reached the slit 7a, so the light emitted from the light sources 8a and 8b has reached the photosensors 9a and 9b, both of which are turned on. Therefore, the inputs of the AND circuit GG, the OR circuit G3, and the reverse movement detector 10 are both at low level (hereinafter referred to as II).
A signal called L II) is given.

Therefore, no clock pulses from the oscillator 11 are applied to the binary counters 12, 13, 14.

At time t1, the coin emits light passing through the slit 7a and 'PItH', so the output of the photo sensor 5)a &', L barbell (hereinafter II l(II and when > vc
Become. The output (II HII) of the photosensor 9a is A
Since the clock pulse from the oscillator 11 is applied to the ND circuit G□, the clock pulse from the oscillator 11 passes through the AND circuit G1 and is input to the binary counter 12.
&c given. This causes the binary counter 12 to start counting clock pulses. Note that the output of the photosensor 9a (II (11)) is also given to the OR circuit G3, so the output of the OR circuit G3 is "H" K.
This is applied to AND circuit G4. As a result, the clock pulses emitted from the oscillator 11 pass through the AND circuit G4 and are applied to the binary counter 14, where they are counted.

At time t, the tip of the coin reaches the position of the slit 7b and cuts off the light passing through the slit 7b, so the output of the photosensor 9b changes from II LII to II J
Changes to II. As a result, one of the inputs of the AND circuit G2, the OR circuit G3 and one input of the reverse movement detector 10 is
It becomes Tor II. Input of AND circuit ()2 or II
Since it depends on HII, the clock pulses emitted from the oscillator 11 are thereafter applied to the AND circuit circuit 0 series 7 counter 13.

At time t3, Naki and the coin pass through slit 7a,
The light emitted from 5'J8a reaches the photosensor 9a. Therefore, the output of the photosensor 9a is +
+ ) (11 to II: [, If K fl 1, this is given to the AND circuit G, G3 and the reverse movement detector 10. As a result, the clock pulse CLK is no longer given to the binary counter 12, The count is stopped. In this way, the count value corresponding to the passing time of the coin 9a is obtained. By the way, since the output of the photosensor 9b remains 11, the output of the photosensor 9a is 11)(++
++ : [, Even after the output of the OR circuit G3 becomes 11, the output of the OR circuit G3 remains 11 ) (++. Therefore, the clock pulse generated by the oscillator 11 continues to be output from the AND circuit G4.
is applied to the binary counter 14 through .

At time t4, the coin passes the position of the slit 7b, and the light emitted from the light source 8b reaches the 7-point sensor 9b. Therefore, the output of the 7 oto sensor 9b is II L
++, which is applied to the input of the AND circuit G2.0R circuit G3 and one input of the reverse movement detector 10.

When one input of the AND circuit G2 becomes II L ++, the clock pulse emitted from the oscillator 11 no longer passes through the AND circuit G2, and counting by the binary counter 13 ends. Furthermore, since the input of II L ++ has already been applied to the other input of the OR circuit G3, the output is inverted from II H++ to IILI+. As a result, the clock pulses emitted from the oscillator 11 no longer pass through the AND circuit 04, and the counting by the binary counter 14 ends.

In this way, in the binary kakuntas 13 and 14, count values corresponding to the time required for the coin to pass through the slit 7b and the time from when the coin starts passing through the slit 7a to when it finishes passing through the slit 7b are obtained. It will be done.

When the binary counters 12, 13, and 14 finish counting the clock pulses, the count values are provided to the determination processing circuit 15, respectively. The judgment processing circuit 15 judges whether or not each count value is within a predetermined allowable range, and when it exceeds the allowable range, a signal is sent to the control section of the coin insertion type actuator (not shown) via a terminal 16. and issues a timeout signal. A timeout signal may be issued when there is a fraudulent act such as string fishing, when the coin is rusted and the speed of movement is reduced, or when a viscous substance (e.g. sugar) is attached to the coin. There are swords whose movement speed is reduced due to the presence of enemies. Therefore, the coin-inserted actuator does not immediately stop operation or issue an alarm, and does not show the inserted coin, since a time-out signal does not immediately indicate fraudulent activity. Eject the coins from the coin outlet.

On the other hand, when the counting of clock pulses by the binary counters 12, 13, and 14 is completed, a count end signal is issued from the determination processing circuit 15 via the terminal 17 (time 15), and this pulse is applied to the AND circuit G5.

Here, the reverse movement detector 10 constituted by a flip 70 tube, a diode, etc. is configured so that the input from the 7-point sensor 9a changes from II L ++ to II as shown in FIG. 3(a).
After reaching H11, the input from 7 Otosensor 9b is
The transition from L ++ to II H++ is II I,
11, and as shown in FIG. 3(b), when the input from the 7-face sensor 9b changes from II L ++ to II H++ before the input from the 7-face sensor 9a changes from It L ++ to ゛・H++. shall output II H11. If you do this, the coin will pass through the slit 7a.
When moving from the coin to the position of the slit 7b, the output of the reverse movement detector 10 after the coin passes the slit 7b becomes II L 11. Therefore, the pulse emitted from the determination processing circuit 15 at time t6 does not pass through the AND circuit G5. However, when the coin moves from the slit 7b to the slit 7a in the opposite direction to the normal position, the coin passes through the slit 7a' and the reverse movement detector 10.
The output is "H" Ic T1. As a result, the pulse emitted from the determination processing circuit 15 at time t5 is A
The signal passes through an ND circuit G5 and is applied to a control section of a coin insertion type actuator (not shown).

If a pulse (reverse movement signal) is emitted from the AND circuit G6, it means that the customer has committed a fraudulent act such as pulling a string, so the coin-operated machine cannot perform the desired operation, and the machine may be stopped or an alarm may be issued. to utter.

Note that the determination processing circuit shown in FIG. 2 can also be integrated into the control section of the coin insertion type actuating device.

According to the embodiment described above and shown in FIG. Since a device is provided for detecting movement in the opposite direction to the direction of movement, a coin insertion device that can clearly detect fraudulent acts such as string fishing can be obtained. Furthermore, since it can be constructed using only 72 photosensors, the cost can also be kept low.

Another embodiment of the present invention will be described by referring to FIGS. 4 and 5. ! FIG. 4 is a circuit diagram of another embodiment, in which the same elements as in FIG. 2 are designated by the same symbols. Unlike the embodiment shown in FIG. 2, this embodiment differs from the embodiment shown in FIG. It is equipped with a circuit that detects whether the coin is larger than the required coin.

The output of the photosensor 9a is given to one input of the AND circuit G1 and the J input of the JK flip-flop 18,
It is assumed that the output of the photosensor 5b is applied to one input of the AND circuit G2, one input of the OR circuit G3, and the input of the JK flip-flop 18. The clock pulses generated by the oscillator 11 are applied to the other inputs of the AND circuits G□ and G2, one input of the AND circuit G4, and the T input of the JK flip-flop 18. The Q output of JK flip-flop 18 is applied to the other input of OR circuit G3 and one input of AND circuit G6, and the output of OR circuit G3 is applied to the other input of AND circuit G4. Further, the AND circuit G is supplied with the outputs of both coin sensors 9a and 9b, and thereby detects whether or not a coin smaller than a prescribed size (diameter) has been inserted. When a coin larger than the specified size is inserted, a scale-out signal is applied from the AND circuit G6 to a coin insertion type actuating device (not shown), which prevents it from performing the desired operation.

Next, the operation of the embodiment shown in FIG. 4 will be explained with reference to FIG. 5. In addition, Fig. 5(a) and (b) show the slit 7.
This is an example when a coin with a diameter smaller than the interval between a and 7b (a coin with a specified thickness) is inserted, and Figure 5 (
C) is an example when a coin whose diameter is larger than the interval between the slits 7a and 7b (a coin with a specified thickness or more) is inserted.

Before time t, the inserted coin has not yet reached 7a, so the light emitted from the light sources 8a and 8b has reached the photosensors 9a and 9b, and both are ONL. Therefore, AND circuit G□, G2,
A signal of 1"L 11 is applied to the inputs of the OR circuit G3 and J of the JK flip-flop 18. Also, the Q output of the JK flip-flop 18 is in the initial state (I
I L II ) remains the same. As a result, the oscillator 11
The clock pulses from the binary counters J2, 13,
14 will not be given.

At time t1, the coin blocks the light passing through the slit 7a, so the output power of the photo sensor 9a is II.
Become a HII. Output of photosensor 9a (II HI
Since the AND circuit circuit voltage (I) is set to 0, the clock pulse from the oscillator 11 passes through the AND circuit G1'2 and is applied to the binary counter 12. This causes the binary counter 12 to start counting clock pulses. Note that the output '(IIHI+) of the photosensor 9a is also given to the J input of the JK79 tube flop 18.

At time t2, T of the JK flip-flop 18
Since the clock pulse applied to the input rises, the Q output becomes II HII in synchronization with this. As a result, O
The output of R circuit G3 also becomes II HII, which is AND
applied to circuit G4. As a result, the clock pulse emitted from the oscillator 11 passes through the AND circuit G4Y and is applied to the binary counter 14, where it is counted.

At time t3, the coin passes the position of the slit 7a, and the light emitted by the light source 8a reaches the photosensor 9a. As a result - the output of the photosensor 9a is II l,
It becomes [, and since this is given to the AND circuit G□, the clock pulse generated from the oscillator 11 no longer reaches the binary counter 12. In this way, the binary counter 121
The counting of clock pulses by c is stopped, and a count value corresponding to the time required for the inserted coin to pass through the slot 7a is given to the determination processing circuit 15. Note that the output of the photosensor 9a is JK flip 70 tube 1.
Since it is also given to the J input of 8, the J input changes from ``H'l to It LIf Vc, but the Q output remains It HIt and does not change. Therefore, the output of OR circuit G3 becomes ``H''.
” remains unchanged, and the clock pulse emitted from the oscillator 11 passes through the AND circuit G4Y and is input to the binary counter 14.
is counted.

At time t4Vc, the coin blocks the light passing through the slit 7b, so the output of the photosensor 9b is II:
[, II changes to "H11. As a result, AND
The inputs to the circuit G2, the OR circuit G3, and the JK flip-flop 180 become If HII. AND circuit G
The input of oscillator 2 becomes II : [(II, so from now on oscillator 1
The clock pulse generated from 1 passes through the AND circuit G2 and is applied to the binary counter 13.

When the clock pulse generated from the oscillator 11 rises at time t5, the Q output of the JK7 lip-flop 18 changes from II l (II to II L 11
to be reversed. By the way, the output of the photosensor 9b "H"
” has already been given to the OR circuit G3 at time t4, so even after the Q output becomes II L 11, the output of the OR circuit G3 remains II l (II. Therefore, the output from the oscillator 11 The clock pulse remains AN after that.
The signal is applied to the binary counter 14 through the D circuit G4Y.

At time t6, the coin passes the position of the slit 7b, and the light emitted from the light source 8b reaches the photosensor 9bvc. Therefore, the output of the photosensor 9b is II J
, II, which is AND circuit G2 % OR circuit G3 input and JK7u tube 70 tube 18'
is given to the input. Then, the clock pulse emitted from the oscillator 11 does not pass through the AND circuit G2 (and the counting by the binary counter 13 ends.
Since the input to the JK flip tube tube 18 becomes II L II, the Q output becomes II I, 11, and therefore O
The outputs of the R circuit G3 are also II I, II K 7. As a result, the clock pulse emitted from the oscillator 11 is A
It no longer passes through the ND circuit G4, and counting by the binary counter 14 ends.

In this way, the binary counters 13 and 14vc are calculated based on the time required for the coin to pass through the slit 7tl1 and the time from when the coin begins to pass through the slit 7a.
A count value corresponding to the time taken to complete the passage is obtained.

When the binary counters 12, 13, and 14 finish counting the clock pulses, the count values are provided to the determination processing circuit 15, respectively. The judgment processing circuit 15 judges whether each count value is within a predetermined tolerance range, and when the count value exceeds the tolerance range, a signal is sent to the control section of the coin insertion type actuator (not shown) via the terminal 16. Issue a timeout signal. A time-out signal may be issued when there is a fraudulent act such as string fishing, when the movement speed decreases because the coin is rusted, or when there is a viscous substance on the coin (for example, sugar).
There are some swords whose movement speed is reduced because they are attached to them. Therefore, even if a timeout signal is issued, it cannot immediately be said that fraudulent activity has been committed, and the coin-inserted actuator does not immediately stop operation or issue an alarm (it does not immediately indicate the inserted coin). Do not eject the coins from the coin ejector.

On the other hand, when the binary counters 12 , 13 , and 14 finish counting the clock pulses, a count end signal is issued from the determination processing circuit 15 (time 17 ), and this pulse is applied to the AND circuit 65 . By the way, Figure 5 (
As shown in a), the coin moves from slit 7a to slit 7.
When moving to position b, the Q output of JK flip 70 knob 18 after the coin passes through slit 7b is II J
, has become II. Therefore, the pulse emitted from the determination processing circuit 15 at time t7 does not pass through the AND circuit G5.

However, as shown in Fig. 5(b), when the coin moves from the slit 7b to the slit 7a in the opposite direction to the normal case, the coin passes through the slit 7a.
The Q output of the K flip-flop 18 is II 1 - I If
It has become. As a result, at time t7, the judgment processing circuit 1
The pulse emitted from 5 is given to the AND circuit 0 series 7 control section.

If a pulse (reverse movement signal) is emitted from the AND circuit G5, this means that the customer has committed a fraudulent act such as pulling a string, so the coin insertion type actuator will stop the device without performing the desired operation. To issue an alarm. Also, T
For machines with a V monitor, a signal from the coin acceptor indicating that a coin has moved in the opposite direction inside the coin inserter is used to indicate 'C01' on the machine's TV monitor.

Moreover, as shown in FIG. 5(a), a slit 7a is provided.

When a coin with a diameter smaller than the interval 7b (including coins of a specified size) is inserted, the photo sensor 9a

Therefore, the outputs of the AND circuit G6 remain III and II. However, as shown in Figure 5(C), Surin)7
When a coin with a diameter larger than the interval between a and 7b (a coin that is not the specified size) is inserted, the photo sensor 9
The outputs of a and 9b may both be 11)(11. Therefore, the output of AND circuit G6 or II)(
11, and this (scale-out signal) is applied to a coin-insertion type actuator (not shown), which does not perform the desired operation.

As described above, according to the embodiment shown in FIG. 4, it is possible to detect that the inserted coin is not moving at a normal speed within the coin guiding member, similar to the embodiment shown in FIG. Not only can it detect fraudulent activities such as sabota, thread fishing, etc.
The present invention provides a coin insertion device that detects whether an inserted coin is of a specified thickness (small diameter) or is too large, and prevents various fraudulent acts.

Another embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. 6 is a circuit diagram of this embodiment, in which the same elements as in FIGS. 2 and 4 are designated by the same reference numerals. In this embodiment, unlike the embodiment shown in FIG.
The distance between a and 7b is set to be approximately equal to and smaller than the diameter of the coin. Also, unlike the embodiment shown in FIG. 2, a circuit is provided for detecting whether the inserted coin is smaller than a specified thickness.

That is, as shown in FIG.
The output logic of b, ff1 (AND) AND [U path G
7, so that it can be detected that the inserted coin reaches the slit 81 after the coin has passed through the slit 8a.

In this case, when a coin of specified thickness (diameter) is inserted, a pulse of AND circuit G7';'v ``I-1'' is emitted as shown in FIG. 7(a)K. ShiD
) When a coin smaller than the thickness of the escape is inserted, the AND circuit G7 does not emit a pulse as shown in Figure 7(b).3 A good coin insertion type operating device as shown in Figure 7 is an AND circuit. When a pulse is emitted from G7, it is determined that a predetermined coin has been inserted, so a desired operation is performed. If a pulse is not emitted, it is determined that the prescribed coin has not been inserted, so the desired operation is not performed.

Similarly, whether or not holes are made in the coins by changing the spacing between the coins or changing the processing method, etc.
It can also detect whether it is a small slag.

Note that the determination processing circuit shown in FIGS. 4 and 6 can also be integrated into the control section of the coin insertion type actuating device.

As described above (according to the present invention), the conventional coin insertion device is provided with two photosensors for detecting the passage of a coin, and based on the signals from the seven sensors, the amount of light required for the coin to move within the coin guide member is A note that is equipped with a timer that measures the time plane and a judgment processing circuit that determines whether the measured time is within a preset tolerance range. It can detect that the vehicle is not moving at a certain speed, and
Since a device for detecting that the coin moves in the opposite direction to the normal movement direction is provided, a coin insertion device that can clearly detect fraudulent acts such as thread fishing can be obtained.

Further, the interval between the two sets of slits is set to be approximately equal to and larger than the diameter of the inserted coin, and a circuit is provided to detect when the inserted coin blocks both slits at the same time. This allows it to be detected that a coin with a diameter larger than the specified value has been inserted. Furthermore-
By setting the interval between the two sets of slits to be approximately equal to and smaller than the diameter of the coin to be inserted, it is possible to detect that a coin with a smaller diameter than the specified value has been inserted, as described above.

A thrown coin guide member, a light source that emits light that passes through each of the two sets of slits, two sensors that detect the light that passes through each of the two sets of slits, and the coin inserted into the coin insertion slot. a device that detects, based on the outputs of the two photosensors, that the coin has reached the slit on the side of the coin acceptor before reaching the slit on the side, and issues a reverse movement signal; ``A device for detecting that the coin has reached the slit on the coin receiving side after passing through the slit based on the outputs of the two 7-inch sensors and emitting a scale-out signal; a first timer that measures the time required for the coin to pass through the slit based on the output of the photosensor provided in the slit; and a first timer that measures the time required for the coin to pass through the slit on the coin acceptor side. A second timer is provided in the slit and measures the time based on the direction of the photo sensor. a third timer that measures the time until the end based on the outputs of the two photosensors; and one of the times measured based on the first, second, and third timers. and a circuit that issues a timeout signal when a preset allowable time range is exceeded for each.
The coin insertion device is characterized in that when the reverse movement signal, the scale-out signal, or the time-out signal is issued, the coin insertion type operating device is caused to perform a predetermined abnormal operation, respectively.
