Description

  The present invention relates to a medal gaming machine in which a plurality of medal sensors are arranged along the distribution direction of medals in order to detect that medals inserted from a medal insertion slot have circulated from upstream to downstream of the medal passage. About.

Conventionally, in order to enjoy a game, a medal gaming machine such as a slot machine that requires a medal for gaming to be inserted into a medal slot has been used.
For example, a slot machine operates a stop button so that a plurality of rotating reels are rotationally driven all at once by operating a start lever, and then the symbols of the rotating reels appearing inside the reel window are in a specific combination. It is a gaming machine.
Here, the slot machine cannot operate the start lever unless the medal is inserted into the medal slot.

Then, as a result of operating the stop button, if the symbols appearing inside the reel window become a specific combination, a winning is established. When the winning is established, the slot machine pays out the number of medals according to the winning combination, thereby making the player entertained.
In such a slot machine, a medal selector that selects whether or not a medal inserted into a medal slot is appropriate, discharges an improper medal, and accepts only a proper medal, and a medal selector There is provided a photoelectric medal passage sensor that is arranged on the downstream side and counts the number of medals determined to be appropriate by the medal selector.
Here, before starting the game, the player counts the number of medals with the medal passage sensor inserted if a certain number of medals are inserted into the medal insertion slot. A certain numerical value is recognized as the number of credits that can be used for games instead of medals. This allows the player to play the game until the number of credits is exhausted without inserting medals into the medal slot, and is freed from the hassle of throwing medals into the medal slot every time the game starts. It has become so.

In addition, when it is desired to end the game halfway, such as before the number of credits is exhausted, the number of medals corresponding to the number of credits can be returned by operating the settlement button or the like.
In the medal gaming machine as described above, if a so-called thread hanging medal with a medal tied to the tip of the thread is inserted into the medal insertion slot, and the thread of the thread hanging medal that is exposed to the outside from the medal insertion slot is operated. The thread-hanging medal can be moved so as to reciprocate before and after the medal passage sensor, whereby the number of credits can be obtained illegally.
In order to prevent such illegal acts caused by the thread medals, two photoelectric medal passage sensors are provided on the downstream side of the medal selector, and these medal passage sensors are arranged along the distribution direction of the medals, There is known a medal gaming machine that can detect that an inserted medal has moved in a reverse direction from downstream to upstream (see, for example, Patent Document 1).

According to such a medal gaming machine, in order to obtain the number of credits with the thread medal, when the thread medal reciprocates around the medal passage sensor, the two medal passage sensors cause the thread medal to move in the reverse direction. Detected, thereby detecting fraudulent acts, and can also prevent fraudulent acts by issuing an alarm sound as necessary.
For such a medal gaming machine equipped with two medal passage sensors, an elongated plate-like instrument having a width smaller than the width dimension of the medal passage set according to the medal diameter is inserted into the medal slot. Then, when reciprocating the tip part of the plate-shaped instrument, the direction is to block the optical path of the two medal passage sensors sequentially from the upstream side at the tip part of the plate-shaped instrument. Then, in order not to block the optical path of the two medal passage sensors, the tip portion of the plate-like instrument is returned to the upstream side from the medal passage sensor, and the reciprocating motion allows the medal gaming machine to detect an illegal act. The number of credits can be obtained illegally.

In order to counter such cheating, it has two sensors that detect the approach of an object with light or magnetism over the entire width direction of the medal passage, and arranges these sensors along the circulation direction of the medal, There is known a medal gaming machine in which the movement of the plate-like instrument described above can be detected by these sensors over the entire width dimension of the medal passage (see, for example, Patent Document 2).
According to such a medal gaming machine, even if the plate-shaped instrument is manipulated skillfully, the plate-shaped instrument cannot be deviated from the detection area of the sensor. Detected, and thereby cheating can be detected.

(Effect of Claim 1)
The present invention configured as described above has the following effects.
That is, according to the first aspect of the present invention, when a deceptive instrument that actively changes a physical quantity corresponding to a sensor that detects the passage of a medal is inserted into the medal insertion slot, the tip of the deceptive instrument is placed on the sensor. Mechanically contacts the passing object detector before reaching. If the tip of the deceptive instrument is further inserted from this state, the passing object detector is pushed away and moved, and movement of the passing object detector is detected by the movement detection sensor. If the movement signal is monitored, it is possible to detect fraudulent acts by fraudulent devices.

  In addition, when the passing object detector is provided to move from the basic position crossing the medal passage along the medal thickness direction, the medal passage is inserted no matter how small the thickness dimension is. Since the fraudulent device cannot reach the sensor unless it pushes away the passing object detector, the movement detection sensor can always detect fraudulent acts by the fraudulent device.

In the above, a passing object detector having a cross-sectional dimension capable of completely closing the medal passage is employed, and the passing object detector moves so that the passing object detector moves from a fully closed position where the medal passage is completely closed. If the passing object detector is provided, even if the fraudulent device is long and thin like a wire, the movement detection sensor can surely detect fraud by the fraud device.
Further, when it is determined whether or not there is an abnormality in the medal path based on the movement signal output from the movement detection sensor, the abnormality can also be determined by the game control device provided in the medal gaming machine. In addition, if various conditions are set in advance to output an abnormal alarm signal, if an abnormality occurs in the medal passage due to the insertion of a fraudulent instrument, the abnormal alarm signal is output reliably. Thus, illegal acts by the fraudulent device are surely notified to the outside.

In addition, the movement signal output from the movement detection sensor due to the circulation of medals does not become a continuous signal but an intermittent signal. Therefore, the movement signal from the movement detection sensor continues for a predetermined time υ or more during the medal insertion possible period. When an insertion possible abnormality detection means for outputting an abnormality notification signal is provided, when the medal can be inserted, no matter how many medals are inserted, the abnormality detection means when the insertion is possible notifies the abnormality. No signal is output.
On the other hand, when the tip of the deception instrument reaches the sensor, the movement signal output from the movement detection sensor becomes a continuous signal that continues for a predetermined time or more when the medal insertion slot is inserted deeper. Therefore, if a fraudulent act is performed with a fraudulent device, the fraudulent act is detected by the abnormality detection means when it can be inserted, and the occurrence of the fraudulent act can be reliably notified to the outside.

In addition, the period during which the medal cannot be inserted is a period during which the detection function is suspended, and the sensor does not react at all even if a fraudulent instrument is inserted. Trying to insert a deception device inside.
On the other hand, when the movement signal is output from the movement detection sensor until the predetermined minute time τ elapses after the transition from the medal insertion impossible period to the medal insertion possible period, an abnormality notification signal is output. When the detection means is provided, when the movement signal is output from the movement detection sensor at the transition from the medal insertion impossible period to the medal insertion possible period, the transition abnormality detection means immediately outputs the abnormality notification signal. Therefore, it becomes possible to quickly notify the outside of the occurrence of fraud.

That is, as shown in FIG. 2, the medal selector 20 is provided with a medal passage 21 for distributing medals along the base plate 20A that supports the components constituting the medal selector 20. The medal passage 21 and the medal insertion slot 11 have dimensions that are slightly larger than the diameter and thickness of the appropriate medal M in the cross section, and are smaller than the appropriate medal M and the appropriate medal M. It is possible to distribute MS.
On the other hand, a medal ML larger than the appropriate medal M cannot be distributed through the medal passage 21 and the medal insertion slot 11.

Here, the medal selector 20 accepts, as shown in FIGS. 2 and 3, a medal M having a diameter within a predetermined range among medals inserted into the medal insertion slot 11 as appropriate. A sorting unit 22 is provided for returning a medal MS having a diameter smaller than a predetermined dimension to the player as inappropriate.
Further, on the downstream side of the sorting unit 22 of the medal selector 20, in order to count the number of medals passing through the sorting unit 22 and heading to the hopper unit 4, a photo interrupter type first sensor 23 and second sensor 24 are provided. Are arranged along the distribution direction of medals.
These sensors 23 and 24 are medal sensors for detecting that medals inserted from the medal insertion slot 11 have circulated from upstream to downstream of the medal passage 21.

The sorting unit 22 will be described in detail. As shown in FIG. 3, the sorting unit 22 is provided in the middle of the tilted medal passage 21 through which the medals M and MS that are tilted from the upright state to the predetermined angle are circulated. Yes. The sorting unit 22 includes an upper engagement collar 22A that engages with the upper side of the periphery of the appropriate medal M, a lower engagement collar 22B that engages with the lower side of the periphery of the medals M and MS, A drop-off opening 22C formed between the upper engagement hook portion 22A and the lower engagement hook portion 22B for dropping an inappropriate medal MS is provided.
Of the medals inserted into the medal insertion slot 11, the medals M having a diameter within a predetermined range are supported by both the upper engaging ridge part 22A and the lower engaging ridge part 22B. The first sensor 23 and the second sensor 24 are sequentially passed to the hopper unit 4. Here, when the appropriate medal M passes through the first sensor 23 and the second sensor 24, the number of credits of the slot machine 1 is increased.

On the other hand, the medal MS whose diameter is smaller than a predetermined dimension is not supported by the upper engagement collar 22A but falls off from the sorting unit 22 through the dropout opening 22C, and is sent to the lower payout port 17. It is like that. As a result, the improper medal MS is prevented from approaching the first sensor 23 and the second sensor 24. As a result, an increase in the number of credits of the slot machine 1 due to the improper insertion of the medal MS is prevented. It has become.
(Route changer 25)
The medal selector 20 as described above is provided with a course switching device 25 that switches an appropriate course of the medal M from one of the hopper unit 4 and the payout opening 17 to the other. This course switching device 25 moves the bottom plate portion 21B of the medal passage 21 in the direction away from the ceiling portion 21A of the medal passage 21 at the portion where the selection portion 22 of the medal passage 21 is formed, as shown in FIG. The proper medal M is allowed to pass through the dropout opening 22C, the proper medal M is dropped from the medal passage 21, and the medal M is advanced toward the payout opening 17.

That is, a side wall portion 21C for forming the inner surface of the medal passage 21 is provided between the ceiling portion 21A and the bottom plate portion 21B of the medal passage 21 as shown in FIGS. The side wall portion 21C is provided with a bracket 21D that protrudes in the direction opposite to the medal passage 21.
At the front end of the bracket 21D, two plate-like portions 26A, 26B intersect with an L shape, and a swing arm 26 whose front end portion is the bottom plate portion 21B of the medal passage 21 is swingably attached. ing.
As shown in FIG. 2, the swing arm 26 has a narrow plate-like portion 26A on the proximal end side attached to the bracket 21D and a wide plate-like portion 26B on the distal end side. Yes. A path switching device 25 is configured including the swing arm 26.

2 to 4, in addition to the swing arm 26 described above, the course switching device 25 is resistant to the biasing means 25A for biasing the swing arm 26 and the biasing force of the biasing means 25A. Thus, a cancel coil 25B for driving the swing arm 26 is provided.
Of these, the biasing means 25A is an extension that biases the swing arm 26 in a direction in which the plate-like portion 26A of the swing arm 26 moves away from the medal passage 21, in other words, in a direction in which the bottom plate portion 21B moves away from the ceiling portion 21A. This is a coil spring of the formula.
At this time, the swing arm 26 is provided so that the plate-like portion 26A can swing between two positions of the swing position α and the swing position β.

Here, in the state where the plate-like portion 26A has reached the swinging position α, as shown in FIG. 3, the plate-like portion 26A comes into contact with the iron core of the cancel coil 25B, and the distance between the ceiling portion 21A and the bottom plate portion 21B is appropriate. The size of the medal M is approximately equal to the diameter of the medal M, and the periphery of the medal M is supported by both the upper engagement collar 22A and the lower engagement collar 22B.
On the other hand, in the state where the plate-like portion 26A has reached the swing position β, the plate-like portion 26A is separated from the iron core of the cancel coil 25B, and the distance between the ceiling portion 21A and the bottom plate portion 21B is as shown in FIG. The size is sufficiently larger than the diameter, so that the upper peripheral edge of the medal M does not reach the upper engaging collar 22A, and the medal M can pass through the dropout opening 22C.

Here, in the slot machine 1, the period from the operation of the start lever 14 to the end of the game is set as a period in which the medal M cannot be inserted, while one game is completed. A period until the start lever is operated in the next game is set as a medal insertion possible period during which the medal M can be inserted.
In the course switching device 25 as described above, during the medal insertion possible period, a current is conducted to the cancel coil 25B, and the plate-like portion 26A of the swing arm 26 is moved to the swing position α as shown in FIG. Thereby, the medal M is advanced to the hopper unit 4.
Further, the path switching device 25 is set in a state in which no current flows through the cancel coil 25B during the period when the medal cannot be inserted, whereby the plate-like portion 26A of the swing arm 26 is moved to the swing position β as shown in FIG. The medal M is advanced to the payout opening 17.

(Passing object detection device 40)
Returning to FIG. 2, the medal selector 20 further mechanically contacts an object passing through the inside of the medal passage 21 on the upstream side of the selecting portion 22 of the medal passage 21, and a predetermined portion in the medal passage 21 is A passing object detection device 40 for detecting an object passing therethrough is provided.
As shown in FIGS. 5 and 6, the passing object detection device 40 includes a passing object detector 41 provided to move when pushed by an object passing through the medal passage 21, and the passing object detector. A movement detection sensor 42 for detecting the movement of 41 is provided.
The movement detection sensor 42 is a photo interrupter type sensor. That is, as shown in FIG. 6, the movement detection sensor 42 includes a light projecting unit 42A provided with a light emitting diode that emits light for detecting an object, and a light receiving unit 42B provided with a photodiode that receives light from the light projecting unit. Are provided at intervals. The movement detection sensor 42 is configured such that when an object enters between the light projecting unit 42A and the light receiving unit 42B, the object blocks light from the light projecting unit 42A, and the light receiving unit 42B outputs a movement signal. It has become. Based on the output of the movement signal, the movement detection sensor 42 can notify the outside of the object.

Here, as shown in FIG. 5, the medal passage 21 is a space formed between the base plate 20A and the side wall portion 21C by disposing the base plate 20A and the side wall portion 21C at intervals.
Then, the passing object detector 41 pushes the passing material passing through the inside of the medal path 21 and the rotating shaft part 41A rotatably supported by the side wall part 21C constituting one side wall of the medal path 21. For this purpose, a contact piece 41B is provided, and a light shielding plate 41C for blocking the light projected by the light projecting portion 42A of the movement detection sensor 42.
Here, when the contact piece 41B is pushed by an object passing through the inside of the medal passage 21, the contact piece 41B moves along the circumferential direction of the passing object detector 41, and the whole rotates. The passing object detector 41 is disposed between the medal slot 11 and the sensors 23 and 24.

As shown in FIGS. 5 and 6, the contact piece 41B is a plate-like portion that protrudes in the radial direction from the outer peripheral surface 41D of the rotating shaft portion 41A and extends in the axial direction of the rotating shaft portion 41A. The vertical dimension H1 of the contact piece 41B is slightly smaller than the vertical dimension H2 of the medal passage 21.
Further, the contact piece 41B is installed so as to start moving from a rotation position γ, which is a basic position crossing the medal passage 21 along the thickness direction of the circulating medal M, and from the medal passage 21. It can be moved to a rotational position δ that deviates.
The light shielding plate 41C is a flat plate having a surface projecting radially from the outer peripheral surface 41D of the rotating shaft portion 41A at a position different from the contact piece 41B in the circumferential direction and having a surface orthogonal to the axial direction of the rotating shaft portion 41A. It is a part of.

Further, the light shielding plate 41C moves between the two positions of the rotation position ε and the rotation position ζ as the contact piece 41B moves between the two positions of the rotation position γ and the rotation position δ. ing.
The rotation position ε is a rotation position where the light shielding plate 41C is completely removed from the space between the light projecting unit 42A and the light receiving unit 42B.
On the other hand, in the rotation position ζ, the light shielding plate 41C enters between the light projecting unit 42A and the light receiving unit 42B, and the light shielding plate 41C blocks the light projected by the light projecting unit 42A toward the light receiving unit 42B. Position. When the light shielding plate 41C arrives at this rotational position ζ, the light from the light projecting portion 42A does not reach the light receiving portion 42B.

Here, the rotation range of the light shielding plate 41C, that is, the rotation range from the rotation position ε to the rotation position ζ is completely out of the medal path 21. The rotation range of the light shielding plate 41C is isolated from the medal passage 21 together with the movement detection sensor 42 by the side wall portion 21C.
As a result, it is impossible to illegally operate the movement detection sensor 42 with an elongated instrument inserted into the medal passage 21.
Here, as shown in FIG. 6, the passing object detector 41 is engaged with a biasing means 43 that biases the contact piece 41B provided on the passing object detector 41 toward the rotational position γ. ing. The urging means 43 is a torsion type coil spring that is arranged substantially coaxially with the rotating shaft portion 41A and urges the rotating shaft portion 41A in a direction to rotate counterclockwise in FIG. Yes.

Here, the urging force of the urging means 43 is such that the contact piece 41B is rotated by the weight of the medal M when the medal M that has circulated through the medal passage 21 contacts the contact piece 41B of the passing object detection body 41. It is set weakly. As a result, when the medal M that has circulated through the medal passage 21 reaches the passing object detection body 41, the biasing force of the biasing means 43 cannot resist the weight of the medal M, and the contact piece 41B moves from the rotation position γ. Thus, the medal M is allowed to pass.
At the same time when the contact piece 41B moves from the rotation position γ, the light shielding plate 41C moves from the rotation position ε and enters the space between the light projecting unit 42A and the light receiving unit 42B. As a result, the light shielding plate 41C blocks the light from the light projecting portion 42A. As a result, a movement signal is output from the light receiving unit 42B, and the movement signal can detect the passage of the coin M that has been distributed through the medal path 21 or the deceptive instrument described above.

(Abnormality detection means 31 when loading is possible and abnormality detection means 32 during transition)
Next, the thrown time abnormality detecting means 31 and the transition abnormality detecting means 32 for determining the presence / absence of an abnormality in the medal passage 21 will be described in detail with reference to FIGS.
As shown in FIG. 7, the abnormality detecting means 31 at the time of insertion and the abnormality detecting means 32 at the time of transition detect whether or not there is an abnormality in the medal passage 21, and if an abnormality is detected, an abnormality alarm is given to the game control device 6. A signal is output. The abnormality alarm signal is received by the game control device 6 as a signal from the second sensor 24.
That is, the game control device 6 is configured to include a microcomputer in which a program for appropriately progressing the game is installed while appropriately controlling each device of the slot machine 1. The game control device 6 is supplied with the output signal of the first sensor 23, the output signal of the second sensor 24, and the two output signals of the abnormality notification device 30.

Further, the game control device 6 outputs a drive command signal to the cancel coil 25B of the medal selector 20.
The abnormality notification device 30 receives a movement signal output from the movement detection sensor 42 and a drive command signal for driving the cancellation coil 25B via the cancellation coil 25B. ing.
This drive command signal is switched from the Hi level to the Lo level when the cancel coil 25B is to be driven, and from the Lo level to the Hi level when the drive of the cancel coil 25B is to be released.

Here, the game control device 6 considers that an appropriate medal M has been inserted only when the output signal of the second sensor 24 is received immediately after receiving the output signal of the first sensor 23, and the number of credits One is added.
On the other hand, the game control device 6 receives the output signal of the first sensor 23 immediately after receiving the output signal of the second sensor 24, or does not receive the output signal of the first sensor 23. When the output signal of the sensor 24 is received, it is considered that an illegal act has been performed and an error signal is output.
As a result, it is possible to determine which of the plurality of slot machines 1 installed in the amusement hall has the slot machine 1 in which the housing 2 is abnormal, and to prevent illegal acts caused by a thread hanging medal or the like. ing.

Of the signals input to the game control device 6, the output signal of the second sensor 24 and the output signal of the abnormality notification device 30 are sent to the game control device 6 via the logic operation means 7 that outputs the logical sum of the input signals. It is designed to be entered. Thereby, the game control device 6 recognizes an abnormality alarm signal that is an output signal output from the abnormality notification device 30 as a signal from the second sensor 24.
Here, in the present embodiment, when it is determined that there is an abnormality in the medal insertion possible period, an abnormality detection means 31 that outputs an abnormality notification signal, and during the transition from the medal insertion impossible period to the medal insertion possible period And a transition abnormality detection means 32 that outputs an abnormality notification signal when it is determined that there is an abnormality.

The insertion-possible abnormality detection means 31 outputs an abnormality notification signal when a movement signal is continuously output from the movement detection sensor 42 for a predetermined time υ during the medal insertion-possible period.
Here, the predetermined time υ is set sufficiently longer than the maximum duration of the movement signal output from the movement detection sensor 42 when the medal M is continuously inserted by manual operation, in other words, in the manual operation. In the continuous insertion of medals M, the duration of the movement signal cannot be reached, and it is set so that the abnormality detection means 31 does not transmit an abnormality alarm signal when the insertion of the medals M is possible.
In addition, when the movement detection sensor 42 outputs the movement signal from the movement detection sensor 42 until a predetermined minute time τ elapses after the transition from the medal insertion impossible period to the medal insertion possible period, An abnormality notification signal is output.

Here, the minute time τ is set to a time sufficiently longer than the duration of noise generated in the surroundings, in other words, a time length that is impossible for noise, and the transition abnormality detection means 32 picks up the noise. Is set so as not to send an abnormal alarm signal.
When the deception device is inserted into the medal slot 11 in order to increase the number of credits illegally, the abnormality detection unit 31 and the transition abnormality detection 31 Any one of the means 32 outputs an abnormality notification signal.
The game control device 6 receives the above-described abnormality notification signal as an output signal of the second sensor 24, and the above-described abnormality notification signal does not accompany the output signal of the first sensor 23, so that an illegal act is performed. An error signal is output.

Here, the insertion possible abnormality detection means 31 and the transition abnormality detection means 32, which are the main parts of the present embodiment, are configured by electronic circuits in which a plurality of elements are assembled and wired on a circuit board. The circuit configuration of this electronic circuit will be described below.
(Circuit configuration of the main part of this embodiment)
FIG. 8 shows a circuit configuration of a main part of the present embodiment. In FIG. 8, the output signals of the first sensor 23, the second sensor 24 and the movement detection sensor 42, and the drive command signal for driving the cancel coil 25B are respectively connected to contacts 23F and 24F whose one ends are grounded. , 42F, 25C.

More specifically, the output signal of the first sensor 23 indicates that the output voltage corresponding to “1” indicating that passage of a medal or the like is detected is Lo level, and that passage is not detected. The output voltage corresponding to “0” becomes Hi level. Therefore, the voltage signal applied to the input terminal 23G of the game control device 6 that receives the output signal of the first sensor 23 can be expressed by the contact 23F OFF (“0”) when the voltage is at the Hi level. Can be expressed by ON (“1”) of the contact 23F, thereby making it easy to explain.
As for the signals of the second sensor 24, the movement detection sensor 42, and the cancel coil 25B, the signal voltages applied to the input terminals 24G, 42G, and 25D that receive these signals are Hi level as in the case of the first sensor 23. When the voltage is at the Lo level, it can be expressed as ON (“1”) of the contact 23F.

Based on the above premise, the circuit configuration of the main part of the present embodiment will be described below.
In FIG. 8, the substrate 33 is formed with an on-loadable abnormality detecting means 31 and a transition abnormality detecting means 32 which are electronic circuits. As for the output signals of the abnormality detection means 31 at the time of enabling and the abnormality detection means 32 at the time of transition, similarly to the output signal of the first sensor 23, the output voltage corresponding to “1” becomes Lo level and corresponds to “0”. Output voltage to be Hi level.
In addition, on the substrate 33, logical operation means 7 for outputting a logical sum of input signals is formed. In this logical operation means 7, the voltage corresponding to “1” in the output signals of the second sensor 24, the abnormality detection means 31 at the time of enabling, and the abnormality detection means 32 at the time of transition becomes the Lo level, and the voltage corresponding to “0” Since it is at the Hi level, it has a simple configuration in which the connection point 7A for connecting the outputs of the second sensor 24, the abnormality detection means 31 at the time of enabling and the abnormality detection means 32 at the time of transition is provided. It has become.

(Abnormality detection means 31 when charging is possible)
If the output signal of the movement detection sensor 42 continues to output the Lo level (“1”) over a predetermined time υ, the electrolysis effect transistors Q4 and Q5 which are two active elements are turned on. A voltage signal of Lo level (“1”) to be output is generated.
That is, a DC resistance R2 and a diode D2 connected in series with each other are provided at the input portion of the possible-on-time abnormality detection means 31. The power supply voltage VDD is applied to the end of the DC resistor R2 where the diode D2 is not connected, and the end of the diode D2 where the DC resistor R2 is not connected, in other words, the negative electrode has movement detection. A sensor 42 (contact 42F in FIG. 8) is connected in series.

A connection point 8A between the DC resistor R2 and the diode D2 is connected to the gate of the field effect transistor Q4 via a DC resistor R4 and a DC resistor R6 connected in series with each other. A connection point 8B between the DC resistor R4 and the DC resistor R6 is grounded via the capacitor C2. Further, the positive point of the diode D3 is connected to the connection point 8A, and the negative electrode of the diode D3 is connected to the connection point 8B.
The diode D3 is connected in parallel with the DC resistor R4 between the connection point 8A and the connection point 8B, whereby the capacitor C2 is quickly charged.
On the other hand, when the movement detection sensor 42 (contact 42F) is turned ON, the capacitor C2 is grounded via the DC resistance R4 and the movement detection sensor 42, and the charge is discharged via the DC resistance R4. The voltage at both ends is gradually decreased.

Here, since the gate voltage of the field effect transistor Q4 is determined by the voltage across the capacitor C2, even if the movement detection sensor 42 (contact 42F) is turned on, it does not drop immediately.
In other words, even when the movement detection sensor 42 is turned on, the field effect transistor Q4 does not immediately turn off, and the predetermined time υ corresponding to the time constant determined by the capacitor C2 and the DC resistance R4 is not obtained. Even after the lapse of time, the circuit is set so as to be in the OFF state only when the movement detection sensor 42 is maintained in the ON state.
The drain of the field effect transistor Q4 and the gate of the field effect transistor Q5 are connected to each other, thereby forming a connection point 8C. A power supply voltage VDD is applied to the connection point 8C via a DC resistor R8. The sources of the field effect transistor Q4 and the field effect transistor Q5 are both grounded. The drain of the field effect transistor Q5 is the output of the abnormality detecting means 31 when it can be turned on, and is connected to the logic operation means 7.

The field effect transistor Q5 has a drain voltage, that is, a Lo level corresponding to “1” when the field effect transistor Q4 is in an OFF state, and an output when the field effect transistor Q4 is in an ON state. The signal is configured to have a Hi level corresponding to “0”.
When the movement detection sensor 42 is turned on, the abnormality detection means 31 at the time of enabling can be set so that the output signal of the field effect transistor Q5 is “1” only when the movement detection sensor 42 is turned on for a predetermined time υ or more. "Lo level corresponding to"", and an abnormal alarm signal is transmitted.

(Transition abnormality detection means 32)
When the drive command signal for driving the cancel coil 25B becomes Lo level (“1”), the transitional abnormality detecting means 32 generates a pulse having a length of a minute time τ by the field effect transistor Q1. The pulse turns the two field effect transistors Q2 and Q3 on, and the movement signal of the movement detection sensor 42 is output to the logic operation means 7 only while the field effect transistors Q2 and Q3 are on. Yes.
That is, the input part of the transition time abnormality detection means 32 is provided with a DC resistor R1 and a diode D1 connected in series with each other. The power supply voltage VDD is applied to the end of the DC resistance R1 where the diode D1 is not connected, and the end of the diode D1 where the DC resistance R1 is not connected, in other words, the negative electrode has a cancel coil. A contact point 25C indicating a drive command signal for 25B is connected in series.

A connection point 9A between the DC resistor R1 and the diode D1 is connected to the gate of the field effect transistor Q1. The power supply voltage VDD is applied to the drain of the field effect transistor Q1 via the DC resistance R3, and the source of the field effect transistor Q1 is grounded.
The drain of the field effect transistor Q1 is connected to the gates of the field effect transistors Q2 and Q3 via the capacitor C1.
A connection point 9B between the gates of the field effect transistors Q2 and Q3 and the capacitor C1 is grounded via a DC resistance R5. The node 9A is connected to the positive electrode of the diode D4 to which the power supply voltage VDD is applied to the negative electrode and the negative electrode of the diode D5 whose positive electrode is grounded.

The diodes D4 and D5 are for absorbing a surge voltage generated when the field effect transistor Q1 is cut off.
Here, when the contact point 25C (the drive command signal for the cancel coil 25B) is turned ON, the gate voltage of the field effect transistor Q1 is lowered, and the field effect transistor Q1 is cut off.
Then, until the predetermined charge is stored in the capacitor C1, a current flows through the DC resistor R5, and a voltage drop occurs at both ends of the DC resistor R5.In other words, a voltage pulse having a time length of a minute time τ is generated by the DC resistor. It occurs at both ends of R5. This minute time τ corresponds to a time constant determined by the capacitor C1 and the DC resistance R5.

In the field effect transistor Q2 to which the voltage pulse having the minute time length is applied to the gate, the power supply voltage VDD is applied to the drain via the DC resistance R7. The drain of the field effect transistor Q2 is the output of the transition abnormality detection means 32 and is connected to the logic operation means 7. The source of the field effect transistor Q2 is connected to the drain of the field effect transistor Q3.
The source of the field effect transistor Q3 is connected to the connection point 8A of the abnormality detecting means 31 when it can be turned on via the diode D6 for preventing backflow.
Such transition abnormality detection means 32, when the contact 25C (the drive command signal for the cancel coil 25B) is turned ON, the field effect transistor Q1 generates a voltage pulse having a time length of a minute time τ. A pulse is applied to the gates of the field effect transistors Q2 and Q3, and the field effect transistors Q2 and Q3 are turned on until a minute time τ elapses.

Then, the drain of the field effect transistor Q2, that is, the output of the transition abnormality detection means 32 is in a conductive state with the movement detection sensor 42, and the movement signal of the movement detection sensor 42 is the output signal of the transition abnormality detection means 32, that is, It is output as it is as an abnormal alarm signal. As a result, when a movement signal is output from the movement detection sensor 42 until a minute time τ elapses after the transition from the medal insertion impossible period to the medal insertion possible period, an abnormality alarm signal is output from the transition abnormality detection means 32. Is to be sent promptly.
(Description of operation of this embodiment)
Next, the operation of the present embodiment when an appropriate medal M is inserted and when a deception device is used will be described.

First, an operation when an appropriate medal M is inserted into the slot machine 1 during the medal insertion possible period will be described.
The slot machine 1 is configured to alternately repeat the medal insertion impossible period and the medal insertion possible period. That is, when the rotation of the rotary reel 3A is started after the medals are first inserted, the medals cannot be inserted, and then the rotation of all the rotary reels 3A is stopped. When the winning determination (determination of winning or losing) is completed, the medal insertion possible period during which medals can be inserted is returned.
Here, as shown in FIG. 9 (A), at time t1, the slot machine 1 shifts from the medal insertion impossible period to the medal insertion possible period, and a cancel coil signal (drive command signal) for driving the cancel coil 25B. ) Switches to “1”. Then, after the time t1, until the time t2 when the rotation of the rotary reel 3A is started, in other words, several medals M are inserted during the transition from the medal insertion possible period to the medal insertion impossible period. Suppose that

Then, as shown in FIG. 9A, when the medal M passes, the medal M moves the contact piece 41B of the passing object detector 41 from the rotation position γ, so that the movement signal of the movement detection sensor 42 is “1”. ”. However, since the time during which one medal M moves the contact piece 41B is shorter than the predetermined time υ, the abnormality alarm signal and the housing error output are both “0” no matter how many medals M pass. ”Is maintained, and it is not switched to“ 1 ”.
Next, a case will be described in which a deceptive device that blinks light so as to deceive the sensors 23 and 24 is inserted into the medal insertion slot 11 before the medal insertion possible period.
As shown in FIG. 9 (B), it is assumed that the fraudulent instrument is inserted into the medal slot 11 at time t3, which is a point before the slot machine 1 shifts from the medal slot period to the medal slot period. .

In this state, when the medal insertion possible period is reached, the movement signal of the movement detection sensor 42 is switched to “1” before the minute time τ elapses from the time t4 when the medal insertion possible period is reached. In FIG. 9B, the minute time τ elapses from the start time t4 of the medal insertion possible period at time t5.
Here, in the period from the start of the medal insertion possible period until the minute time τ elapses, the movement signal of the movement detection sensor 42 becomes the abnormality alarm signal as it is, as described above. At the time of switching to “1”, that is, substantially the same time as the time t4 when the medal insertion possible period is started, the abnormality alarm signal is switched to “1”. Then, after a minute time delay after the abnormal alarm signal is switched to “1”, the housing error output is switched to “1”, and the cancel coil signal (drive command signal) is returned to “0”. The function stops. For this reason, an abnormal alarm signal is output without giving time for performing fraud with the fraudulent device, and fraud is prevented in advance.

Next, the case where an attempt is made to cheat with a fraudulent instrument during the medal insertion possible period will be described.
As shown in FIG. 9C, the deceptive instrument is inserted into the medal insertion slot 11 at a time t8 after a time t7 when a minute time τ has elapsed from the time t6 when the medal insertable period starts. It is assumed that the front end portion moves the contact piece 41B of the passing object detector 41 from the rotation position γ, and the movement signal of the movement detection sensor 42 is switched to “1”. More precisely, it is assumed that the movement signal of the movement detection sensor 42 is switched to “1” at time t8.
Here, the predetermined time υ is set to a time length in which the continuous time of the movement signal cannot be reached by continuous insertion of the medal M by manual operation, and can be inserted even if the medal M is continuously input by manual operation. The hour abnormality detection means 31 does not send out an abnormality alarm signal, so that the insertion of the medal M and the insertion of the deception device are discriminated.

For example, if the insertion of the cheating instrument into the medal slot 11 continues until time t10 after the time t9, at time t9 when a predetermined time υ has elapsed from the time t8 when the cheating instrument is inserted into the medal slot 11. The abnormality alarm signal is switched to “1”, and after a slight time delay after the abnormality alarm signal is switched to “1”, the housing error output is switched to “1”, and the cancel coil signal (drive command signal) is “0”. ”, The functions of the sensors 23 and 24 are stopped. For this reason, an abnormality alarm signal is output immediately before the number of credits is increased by the fraudulent device, and fraud is prevented in advance.
As described above, during the medal insertion possible period, even if a fraudulent instrument is inserted into the medal insertion slot 11 to increase the number of credits illegally, an abnormality alarm signal and a housing error output are transmitted. Since the functions of the sensors 23 and 24 are stopped, an increase in the number of unauthorized credits due to fraudulent devices is also prevented.

Further, only when the duration of the movement signal output from the movement detection sensor 42 is long, it is determined that the fraudulent instrument has been inserted into the medal slot 11, so that the medal M inserted into the medal slot 11 is a passing object detector. Even if the contact piece 41B of 41 is accessed, there is no transmission of an abnormal alarm signal and housing error output, the function of the sensors 23, 24 is not stopped, and the game proceeds as usual if there is no fraud.
(Effect of embodiment)
According to this embodiment as described above, the following effects can be obtained.
That is, since the passing object detector 41 is provided on the upstream side of the sensors 23 and 24 in the medal passage 21, when the deceptive instrument is inserted into the medal insertion slot 11, the tip portion of the deceptive instrument is connected to the sensors 23 and 24. Prior to reaching, the passing object detector 41 is contacted, and the contact piece 41B of the passing object detector 41 is pushed away and moved. Since the movement of the passing object detector 41 is detected by the movement detection sensor 42, if the movement signal output from the movement detection sensor 42 is monitored, it is possible to reliably detect fraud by the deception instrument.

In addition, since the contact piece 41B of the passing object detection body 41 is rotatably provided starting from a rotation position γ, which is a basic position crossing the medal passage 21 along the thickness direction of the medal M, the deception device No matter how small the thickness dimension, the deception device inserted in the medal passage 21 cannot reach the sensors 23 and 24 unless it pushes away the contact piece 41B of the passing object detector 41. The sensor 42 can always detect an illegal act by a fraudulent instrument.
Further, since it is configured to determine whether or not there is an abnormality in the medal path 21 based on the movement signal output from the movement detection sensor 42, the duration of the movement signal output from the movement detection sensor 42 is long. Various conditions for outputting an abnormal alarm signal, such as outputting an abnormal alarm signal only in the case, can be set in advance in the abnormality notification device 30, so that there is an abnormality in the medal passage 21 due to the insertion of a fraudulent instrument. When it occurs, it is possible to reliably detect an abnormality and output an abnormality alarm signal, so that an illegal act by a deception device can be reliably notified to the outside.

  Furthermore, in the continuous insertion of the medal M by manual operation, even if the predetermined time υ is set as the length of time during which the duration of the movement signal cannot be reached and the medal M is continuously inserted by manual operation during the medal insertion possible period, Since the abnormality warning signal is not transmitted, and when the duration of the movement signal exceeds the predetermined time υ, the deception device is provided with an insertion-possible abnormality detection means 31 that determines that the deception device has been inserted into the medal insertion slot 11. In addition, it is possible to reliably detect fraudulent acts caused by the system, and when the medal M is inserted into the medal insertion slot 11, the alarm alarm signal and the housing error output are not transmitted and the functions of the sensors 23 and 24 are not stopped. If there is no cheating, the game can proceed as usual.

In addition, since the minute time τ is sufficiently longer than the duration of noise generated in the surroundings, in other words, the minute time τ is a time length that is impossible for noise. When the abnormality detection means 32 does not malfunction due to noise, and the deception device is inserted into the medal insertion slot 11, when the medal insertion impossible period shifts to the medal insertion possible period, the movement detection sensor 42 When the movement signal is output, the transition abnormality detection means 32 immediately outputs the abnormality notification signal, so that it is possible to quickly notify the outside of the occurrence of fraudulent activity by the fraudulent instrument.
In addition, this invention is not limited to the said embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included.

For example, the passing object detector is not limited to the one having a contact piece that is pushed away and rotated when pushed by an object passing through the inside of the medal passage, and passes through the inside of the medal passage 21, as shown in FIG. When pressed by an object such as a medal M, the passing object detection body 45 having a contact piece 45B that moves backward, that is, linearly moves, may be used.
Further, the contact piece of the passing object detector is not limited to one whose vertical dimension is slightly smaller than the vertical dimension of the medal passage 21, and as shown in FIG. The contact piece 45B may be slightly larger than the vertical dimension H2 of the medal passage 21 and can completely close the medal passage 21 at the basic position.

If such a contact piece 45B is adopted, even if the deception device is elongated like a wire, the movement detection sensor 42 can always detect an illegal act by the deception device.
Further, the medal sensor and the movement detection sensor are not limited to the photo-interrupter type sensor, but may be a magnetic coil type sensor that reacts to magnetism. The specific detection principle and mechanism of the medal sensor and the movement detection sensor are appropriately determined in the implementation. Can be set.
In addition, the means for detecting an abnormality in the medal path is not limited to hardware such as an electronic circuit in which elements such as transistors and DC resistors are combined, but is digitally programmed so as to realize a predetermined operation. It may be configured to include software such as a sequencer.
