Description

  The present invention relates to a gaming machine having a control means for starting the progress of a game, for example, triggered by detection of an operation by a player, and a slot machine.

  As a gaming machine in which a player inserts game media and enjoys a game, the player rotates the reel on which a plurality of symbols are drawn in response to the player's operation, and depending on the symbol when stopped at an appropriate timing, the player There is a spinning machine (hereinafter referred to as a slot machine) that gains profits.

  Such a slot machine selects one result lottery result by internal lottery in response to the player's operation, and a game control board called a main control board or main control board that controls the start and stop of rotation of the reel. Various operations related to the game are controlled by a sub-control board that controls a production operation by voice or light emission according to the result of lottery or a production control board called a sub-control board (see Patent Document 1).

  By the way, Patent Document 1 proposes a technique for suppressing a game using an unauthorized device for falsifying control information transmitted from a game control board to an effect control board. Specifically, Patent Literature 1 adds a cumulative value in the main board and the sub board every time a command is transmitted from the main board to the sub board, and after the completion of one game, the cumulative value transmitted from the main board. The sub-board compares and determines the value and the accumulated value stored in the sub-board, and notifies if the accumulated values do not match. As a result, Patent Document 1 is said to be able to suppress a game using an unauthorized device that falsifies a command.

  However, in the technique of Patent Document 1, by inputting a start switch signal or the like that triggers the start of an internal lottery to the game control board, an action that automatically repeats the game, that is, a so-called driving machine is used. The deterrent effect cannot be obtained.

Specifically, when the start switch is on and the driving machine connected to the power supply line supplying power intermittently repeats the supply and cut-off of power to the start switch, the signal of the start switch controls the game. Since the game machine is repeatedly input to the board, the game machine automatically advances the game.
In this case, since there is no difference between the cumulative value transmitted by the game control board and the cumulative value stored by the production control board, the technique of Patent Document 1 cannot detect an action using a driving machine, The deterrent effect cannot be obtained.

  For this reason, the game store was able to improve the ability to attract customers by setting the slot machine just before the big hit using a driving machine before the store opened. However, the act using such a driving machine lacks the fairness of the game, and there is a risk that the player's gambling will be greatly reluctant.

Japanese Patent Laid-Open No. 2013-22096

  In view of the above-described problems, an object of the present invention is to provide a gaming machine and a slot machine that can prevent a fraudulent act that provokes a player's gambling and can ensure fairness of the game.

The present invention, at least one operation switch to permit operation by Yu technique's and game control board having game control means for controlling the progress of a game, a detection operation by the player who before Symbol operated switch is output and an operation detection signal transmission means for transmitting an operation detection signal shown in the game control unit, a gaming machine progresses the game by the internal lottery of the game control unit, together with the operating switch is connected, the It includes a connection board game control board is connected, a first power supply means for supplying power to the game control unit, and a second power supply means for supplying power to the operating switch through the connection substrate , the connection substrate, as well as driven by the power of the previous SL first power supply means comprises a voltage monitoring means for monitoring the voltage of the second power supply means, said voltage monitoring means If the voltage of the second power supply unit falls below the reference voltage, and configured to output a predetermined signal to the game control means connected at a given signal transmitting means, said game control means, from said voltage monitoring means A voltage error executing means for executing a predetermined error operation when the predetermined signal is input is provided.

The operation switch is a switch composed of a non-contact sensor or the like that is driven by receiving power supply, and may be, for example, a start switch, a bet switch, a stop switch, or a chance switch in a spinning cylinder type game machine. I can .

The gaming machine can be a spinning-type gaming machine or a pachinko gaming machine.
The first power supply unit and the second power supply unit may be a unit that supplies power from the same power source or a unit that supplies power from different power sources.

The operation detection signal transmission means, medium detection signal transmission means, and predetermined signal transmission means are means for electrically transmitting a signal, means for transmitting a signal by optical communication, means for transmitting a signal wirelessly, etc. Can do.
The predetermined error operation may be an error operation that stops the progress of the game, an error operation that does not perform internal lottery, or an operation that is notified by video, audio, and light emission.

According to the present invention, it is possible to prevent an illegal act that provokes the player's happiness and to ensure the fairness of the game.
Specifically, since the supply of power from the first power supply unit is accepted, the voltage monitoring unit does not stop its operation even when the power supply from the second power supply unit is interrupted, for example. .

Therefore, even when a driving machine that intermittently shorts the second power supply means is used, the voltage monitoring means can stably monitor the voltage of the second power supply means, and the game control means In contrast, a predetermined signal can be reliably output.
And when a predetermined signal is acquired, a game machine can suppress that a game advances automatically by a driving machine by performing a predetermined error operation. Thereby, the gaming machine can suppress, for example, being set to the state immediately before the jackpot.

  Furthermore, when the power is cut off except for a predetermined procedure, the gaming machine may cause an error in the control operation of the game control means. On the other hand, even if the power of the second power supply means is cut off by the driving machine, the game control means can continue its control operation with the power from the first power supply means. For this reason, the gaming machine can prevent an unintended error from occurring and prevent the execution of a predetermined error operation from being hindered.

In addition, by providing the voltage monitoring means on the connection board configured separately from the game control board, the gaming machine can prevent an increase in the number of parts on the game control board and the game control board according to the progress of the game The redesign of can be eliminated.
Therefore, the gaming machine ensures the fairness of the game by suppressing illegal acts that provoke the player's happiness by using voltage monitoring means provided on a connection board configured separately from the game control board. be able to.

As aspect of the invention, the gaming machine, are located in the medium flow path Yu technique medium flows, a medium sensor unit for detecting the insertion of the game medium by the player, the medium detection sensor unit has outputs Medium detection signal transmission means for transmitting a medium detection signal indicating detection of the game medium to the game control means, the connection board and the medium detection sensor unit are connected, and the medium detection sensor unit is A first medium detection sensor which is arranged upstream of the medium flow path and outputs a first medium detection signal indicating detection of the game medium to the game control means connected via the first medium detection signal transmission means And the game control means disposed in the medium flow path downstream of the first medium detection sensor and connected via the second medium detection signal transmission means. A second medium detection sensor that outputs a second medium detection signal indicating the detection of the medium, and the voltage monitoring means is configured to output the predetermined signal when the voltage supplied to the operation switch is equal to or lower than a reference voltage. The second medium detection signal is output to the game control means, and when the first medium detection signal and the second medium detection signal are not input to the game control means in this order, the predetermined error operation is executed. It is possible to provide a medium detection error executing means.

The medium detection sensor unit is a sensor unit configured by a non-contact sensor or the like that is driven by receiving supply of electric power, such as a sensor unit that detects passage of a game medium, or a sensor unit that identifies authenticity of a game medium. It can be. Furthermore, the medium detection sensor unit can be a unit configured with one medium detection sensor or a unit configured with a plurality of medium detection sensors.
According to the present invention, the gaming machine can achieve both detection of an illegal act using a driving machine and detection of an illegal insertion of a game medium while suppressing an increase in the number of parts.
Specifically, for example, an illegal act of playing a game by inserting a gaming medium with a string and then removing the gaming medium by pulling the string, causing the gaming machine to erroneously detect the insertion of the gaming medium. There is.

  On the other hand, by providing the first medium detection sensor, the second medium detection sensor, and the medium detection error execution means, the gaming machine can prevent the game from proceeding due to illegal insertion of the game medium.

  Specifically, when a game medium is illegally inserted, the first medium detection signal and the second medium detection signal are not input in this order, or only one of the first medium detection signal and the second medium detection signal is input. Therefore, the game control means can identify that it is not a normal game medium input. Thereby, the gaming machine can detect the illegal insertion of the game medium and prevent the progress of the game.

  On the other hand, the voltage monitoring means can output a predetermined signal as the second medium detection signal when detecting a change in the voltage supplied to the operation switch. That is, when the voltage monitoring means detects a change in voltage supplied to the operation switch, only the second medium detection signal is input to the game control means, so that the gaming machine performs a predetermined error operation by the medium detection error execution means. Can be executed.

Thereby, the gaming machine can realize the detection of the driving machine and the detection of the illegal insertion of the game medium with the same program. For this reason, the gaming machine can suppress the data size of the program that realizes the voltage error execution means, and can prevent the limited storage capacity of the game control means from being compressed.
Therefore, the gaming machine uses voltage monitoring means that outputs a predetermined signal as the second medium detection signal, so that the detection of illegal acts using the driving machine and the detection of illegal insertion of gaming media It is possible to achieve both of them by suppressing the increase of.

Further, as an aspect of the present invention, provided on the upstream side of the medium detection sensor unit in the medium flow path is provided with a flow path switching means for switching the medium flow path in a direction to return the inserted game medium to the player. The medium detection error execution means is configured not to execute the predetermined error operation until an elapsed time after switching the medium flow path in a direction to return the game medium to the player reaches a predetermined elapsed time. The voltage monitoring means may be configured to output the predetermined signal to the game control means for a predetermined time longer than the predetermined elapsed time when the voltage becomes equal to or lower than a reference voltage .

According to the present invention, the gaming machine can more surely suppress an illegal act that provokes the gambling feeling of the player.
Specifically, for example, when more than a predetermined number of game media that can be stored as credits are input, the gaming machine switches the medium flow path and returns the input game media to the player. When switching the medium flow path, by setting a predetermined elapsed time during which the error operation is not executed, the gaming machine can control the number of game media exceeding the predetermined number even if the medium flow path switching by the flow path switching unit is delayed. It prevents the occurrence of errors due to detection.

  For this reason, for example, even if only the second medium detection signal is input to the game control means during a predetermined elapsed time, the medium detection error execution means does not execute a predetermined error operation. In other words, if the driving machine short-circuits the second power supply means during a predetermined elapsed time, the gaming machine may progress the game.

Therefore, the medium detection error executing means, that is, the voltage error executing means outputs the second power during the predetermined elapsed time by the voltage monitoring means for outputting the predetermined signal to the game control means for a predetermined time longer than the predetermined elapsed time. Even when the supply means is short-circuited, a predetermined error operation can be reliably executed.
Therefore, the gaming machine can surely detect a short circuit of the second power supply means, and can more reliably suppress an illegal act that instigates the player's joy.

As an aspect of the present invention, the predetermined signal transmission means can be the second medium detection signal transmission means.
According to the present invention, the gaming machine can suppress an increase in the number of parts and suppress an illegal act that provokes the player's happiness.

  Specifically, the transmission means for transmitting the predetermined signal output from the voltage monitoring means to the game control means and the transmission means for transmitting the second medium detection signal output from the second medium detection sensor to the game control means are shared. Therefore, the gaming machine can reduce the number of parts such as terminals, connectors, and signal lines.

Furthermore, since the predetermined signal output can be input to the game control means via the second medium detection signal transmission means, the gaming machine suppresses an increase in the number of parts and circuit patterns on the game control board, and voltage error execution means. And the complication of the program which implement | achieves a medium detection error execution means can be suppressed more.
Therefore, the gaming machine can suppress an increase in the number of parts by using the predetermined signal transmission means as the second medium detection signal transmission means, thereby suppressing an illegal act that provokes the player's happiness. it can.

  The present invention is also a slot machine constituted by the above-described gaming machine, wherein one operation switch is a start switch in which detection of an operation by a player triggers the start of internal lottery in the game control means, and the voltage monitoring means Is configured to monitor the voltage supplied to the start switch.

According to the present invention, it is possible to prevent an illegal act that provokes the player's happiness and to ensure the fairness of the game.
Specifically, by using voltage monitoring means for monitoring the voltage supplied to the start switch, the slot machine can control the game even if the operation detection signal from the start switch is output by the driving machine. The start of the internal lottery can be prevented.

Thereby, the slot machine can suppress an illegal act such as setting a state just before the big hit using a driving machine.
Accordingly, the slot machine can ensure the fairness of the game by suppressing an illegal act that instigates the player's gambling by the voltage monitoring means for monitoring the voltage supplied to the start switch.

In addition, a voltage signal of Lo level is output to the sensor signal line SL7.

  The connection board 26 receives a supply of power from the second power line PW2, and supplies power to the maximum bet switch 15, the bet switch 16, the stop switch 17, the start switch 18, and the medal selector 23, and a harness 36. A function of outputting a voltage signal output from each switch to the game control device 40.

  Further, as shown in FIG. 6, the connection board 26 includes a power supply voltage monitoring circuit 27 that is driven by the power of the first power line PW1 supplied from the game control device 40 via the harness 36. The power supply voltage monitoring circuit 27 monitors the voltage drop of the power supply voltage Vb applied to the connection board 26, and when the power supply voltage Vb becomes equal to or lower than the reference voltage, the game control board 41 is output during the output time T1 (see FIG. 8). The low-level voltage signal is input to the downstream terminal 41b.

More specifically, the power supply voltage monitoring circuit 27 includes a transistor Q and a pulse generation circuit 27a connected to the transistor Q.
The transistor Q has a function as a switch that operates based on the output from the pulse generation circuit 27a. The transistor Q has a collector connected to the pattern wiring 26a of the connection substrate 26 connected to the sensor signal line SL7, an emitter grounded, and a base connected to the pulse generation circuit 27a via the resistor R1.

  The pulse generation circuit 27a is an integrated circuit that is driven by the power supply voltage Va applied through the harness 36, and includes a power supply terminal to which the power supply voltage Va is applied, a trigger terminal connected to the power supply voltage Vb, and a transistor Q. An OUT terminal to be connected is provided. When the trigger terminal voltage exceeds the reference voltage, the pulse generation circuit 27a outputs a Lo level voltage signal from the OUT terminal. When the trigger terminal voltage is equal to or lower than the reference voltage, the pulse generation circuit 27a is at the Hi level for the output time T1. A voltage signal is output from the OUT terminal.

  In the power supply voltage monitoring circuit 27 configured as described above, when the power supply voltage Vb applied to the connection substrate 26 becomes equal to or lower than the reference voltage, the transistor Q connected to the OUT terminal of the pulse generation circuit 27a is turned on. For this reason, a Lo level voltage signal can be input to the downstream terminal 41b of the game control board 41 during the output time T1.

In the slot machine 1 having such a configuration, medal detection control for detecting normal insertion of medals based on voltage signals input to the upstream terminal 41a and the downstream terminal 41b will be described in detail with reference to FIG. .
FIG. 7 shows a flowchart of medal detection control in the game control device.

When the power switch 33a is turned on, the first CPU 44c of the first microcomputer 44 starts the medal detection control by executing the program stored in the first ROM 44a.
When the medal detection control is started, the first CPU 44c determines whether or not the solenoid 23a is on (step S101).

When the solenoid 23a is off (step S101: No), the first CPU 44c determines whether or not a Lo level voltage signal is input to the downstream terminal 41b (step S102).
When the Lo-level voltage signal is input to the downstream terminal 41b (step S102: Yes), the first CPU 44c is in a state where the solenoid 23a is off, that is, all inserted medals are discharged to the medal payout port 21. Since the medal flowing down to the hopper unit 32 is detected, it is identified that the medal is not normally detected, and an error operation is executed (step S103).

At this time, as the error operation, for example, the first CPU 44c stops the progress of the control operation in the game control device 40 and performs an audio notification through the effect control device 50. The error operation by the first CPU 44c is repeatedly performed until the power is turned off by operating the power switch 33a.
On the other hand, when the Lo-level voltage signal is not input to the downstream terminal 41b in step S102 (step S102: No), the first CPU 44c ends the medal detection control.

In step S101, when the solenoid 23a is on (step S101: Yes), the first CPU 44c determines whether or not a Lo level voltage signal is input to the upstream terminal 41a or the downstream terminal 41b (step S104). .
When the Lo level voltage signal is not input to the upstream terminal 41a or the downstream terminal 41b (step S104: No), that is, the Hi level voltage signal is input to the upstream terminal 41a and the downstream terminal 41b. If there is, the first CPU 44c waits until a Lo level voltage signal is input to the upstream terminal 41a or the downstream terminal 41b.

  On the other hand, when the Lo level voltage signal is input to the upstream terminal 41a or the downstream terminal 41b (step S104: Yes), the first CPU 44c determines the Lo level voltage signal in the order of the upstream terminal 41a and the downstream terminal 41b. It is determined whether or not is input (step S105).

  When the Lo level voltage signal is not input in the order of the upstream terminal 41a and the downstream terminal 41b (step S105: No), the first CPU 44c does not normally flow down the inserted medal toward the hopper unit 32. The state or the inserted medal is identified as being extracted from the medal slot 14, and the process proceeds to step S103 to execute an error operation.

  On the other hand, when the Lo level voltage signal is input in the order of the upstream terminal 41a and the downstream terminal 41b (step S105: Yes), the first CPU 44c assumes that the inserted medal has flowed normally toward the hopper unit 32. The identified and detected medals are counted as valid medals (step S106) and temporarily stored in the first RAM 44b.

  At this time, when the number of medals stored in the first RAM 44b reaches the maximum number used in one game, the first CPU 44c enables the player to accept the operation of the start switch 18. Alternatively, when the number of medals stored in the first RAM 44b exceeds the maximum number used in one game, the detected medals are counted as credits. The maximum number used in one game is, for example, three.

Thereafter, the first CPU 44c determines whether or not the number of credits has reached the upper limit number (step S107). The upper limit number is, for example, the number that can be stored in credits, and is 50 in this embodiment.
If the number of credits is less than the upper limit number (step S107: No), the first CPU 44c ends the medal detection control.

  If the number of credits has reached the upper limit (step S107: Yes), the first CPU 44c starts timing and turns off the solenoid 23a (step S108). At this time, the first CPU 44c temporarily stores a time count value indicating the elapsed time in the first RAM 44b and updates the time count value according to the elapsed time.

When the solenoid 23a is turned off, the first CPU 44c determines whether or not the time count value has reached a threshold value (step S109). The threshold value is a value indicating a time shorter than an output time T1 in the power supply voltage monitoring circuit 27 (elapsed time T2 described later).
If the time count value has not reached the threshold value (step S109: No), the first CPU 44c waits until the time count value reaches the threshold value.

On the other hand, when the time count value reaches the threshold (step S109: Yes), the first CPU 44c resets the time count value (step S110) and ends the medal detection control.
Note that the slot machine 1 repeats the above-described steps S101 to S110 until the power switch 33a is turned off.

Subsequently, in the slot machine 1 that detects the normal insertion of medals in this way, the power supply voltage Vb, the voltage signal, and the error operation state when the driving machine is used will be described with reference to FIGS. 8 and 9. To do.
8 shows a timing chart when the second power line PW2 is short-circuited with the solenoid 23a being on, and FIG. 9 is a timing when the second power line PW2 is short-circuited at a timing when the solenoid 23a is switched off. A chart is shown.
The driving machine is a driving machine that short-circuits the second power line PW2 in order to output a voltage signal from the start switch 18 that is turned on by applying a load such as a weight.

First, the case where the second power line PW2 is short-circuited when the solenoid 23a is on will be described with reference to FIG.
As shown in FIG. 8, when the upstream detection sensor 23b of the medal selector 23 detects the inserted medal in the state where the solenoid 23a is on, the voltage signal output from the upstream detection sensor 23b becomes Lo level. Therefore, a Lo level voltage signal is input to the upstream terminal 41 a of the game control board 41.

  Thereafter, when the downstream detection sensor 23c of the medal selector 23 detects the flowing-down medal, the voltage signal output from the downstream detection sensor 23c becomes Lo level. Therefore, a Lo level voltage signal is input to the downstream terminal 41 b of the game control board 41.

  Therefore, the first CPU 44c executing the medal detection control shown in FIG. 7 outputs the Lo level voltage signal in the order of the upstream terminal 41a and the downstream terminal 41b when the solenoid 23a is on (step S101: Yes). Since it has been input (step S104: Yes and step S105: Yes), the inserted medal is counted as a valid medal (step S106). That is, since the Lo level voltage signal is input in the order of the upstream terminal 41a and the downstream terminal 41b, the slot machine 1 does not execute the error operation and validates the operation of the start switch 18.

In this state, when the driving machine short-circuits the second power line PW2, the power supply voltage Vb becomes equal to or lower than the reference voltage, and the power supply voltage monitoring circuit 27 outputs a Lo level voltage signal to the downstream terminal 41b during the output time T1. Let them enter.
Therefore, the first CPU 44c executing the medal detection control shown in FIG. 7 outputs the Lo level voltage signal in the order of the upstream terminal 41a and the downstream terminal 41b when the solenoid 23a is on (step S101: Yes). Since no input is made (step S104: Yes, step S105: No), an error operation is executed (step S103).

Next, a case where the second power line PW2 is short-circuited when the solenoid 23a is switched from the on state to the off state will be described with reference to FIG.
As shown in FIG. 9, when the upstream detection sensor 23b detects the inserted medal in a state where the solenoid 23a is on, the voltage signal output from the upstream detection sensor 23b becomes Lo level. For this reason, a Lo level voltage signal is input to the upstream terminal 41a.

  Thereafter, when the downstream detection sensor 23c detects the dropped medal, the voltage signal output from the downstream detection sensor 23c becomes Lo level. For this reason, a Lo level voltage signal is input to the downstream terminal 41b.

  That is, the first CPU 44c executing the medal detection control shown in FIG. 7 outputs the Lo level voltage signal in the order of the upstream terminal 41a and the downstream terminal 41b when the solenoid 23a is on (step S101: Yes). Since it has been input (step S104: Yes and step S105: Yes), the inserted medal is counted as a valid medal (step S106).

  At this time, when the number of credits reaches the upper limit number (step S107), the slot machine 1 switches the solenoid 23a to an off state and waits until the time count value reaches a threshold value (steps S108 and S109). In other words, the first CPU 44c does not perform any control operation according to the state of the solenoid 23a and the input level of the voltage signal during the elapsed time T2.

  When the driving machine short-circuits the second power line PW2 during this elapsed time T2, the power supply voltage Vb becomes equal to or lower than the reference voltage, and the power supply voltage monitoring circuit 27 sends the Lo level voltage signal downstream during the output time T1. Input to the side terminal 41b. However, as described above, during the elapsed time T2, the first CPU 44c does not execute an error operation.

Since the elapsed time T2 is shorter than the output time T1, the Lo-level voltage signal is input to the downstream terminal 41b even when the elapsed time T2 has elapsed.
Therefore, the first CPU 44c executing the medal detection control shown in FIG. 7 receives the Lo level voltage signal to the downstream terminal 41b when the solenoid 23a is off (step S101: No) (step S102). : Yes), an error operation is executed (step S103).

The slot machine 1 that realizes the above-described operation can prevent an illegal act that provokes the player's joy, and can ensure the fairness of the game.
Specifically, since the supply of power from the first power line PW1 is received via the game control board 41, the power supply voltage monitoring circuit 27 can be controlled even if the power supply from the second power line PW2 is interrupted, for example. Does not stop operation.

For this reason, even when a driving machine for intermittently short-circuiting the second power line PW2 is used, the power supply voltage monitoring circuit 27 can stably monitor the power supply voltage Vb and downstream the Lo level voltage signal. It can be input to the side terminal 41b.
When the Lo level voltage signal is input only to the downstream terminal 41b, the slot machine 1 can suppress the game from proceeding automatically by the driving machine by executing the error operation. Thereby, the slot machine 1 can suppress, for example, being set to the state immediately before the big hit.

  Furthermore, when the power is interrupted by a procedure other than a predetermined procedure, the slot machine 1 may cause an error in the control operation in the first microcomputer 44. On the other hand, even if the power of the second power line PW2 is cut off by the driving machine, the first microcomputer 44 can continue the control operation by the power from the first power line PW1. For this reason, the slot machine 1 can prevent an unintended error from occurring and prevent the execution of the error operation from being hindered.

In addition, since the power supply voltage monitoring circuit 27 is provided in the connection board 26 configured separately from the game control board 41, the slot machine 1 can prevent an increase in the number of parts in the game control board 41 and It is possible to eliminate the need to redesign the game control board 41 for the progress.
Therefore, the slot machine 1 suppresses an illegal act that provokes the player's gambling feeling by the power supply voltage monitoring circuit 27 provided on the connection board 26 configured separately from the game control board 41, Fairness can be ensured.

  In addition, when the power supply voltage Vb is equal to or lower than the reference voltage, the power supply voltage monitoring circuit 27 is configured to input a Lo level voltage signal to the downstream terminal 41b, and the Lo level voltage signal is sequentially input to the upstream terminal 41a and the downstream terminal 41b. If no is input, the first machine 44c executing the error operation causes the slot machine 1 to perform both detection of an illegal action using the driving machine and detection of an illegal insertion of a medal while suppressing an increase in the number of parts. be able to.

Specifically, for example, there is an illegal act of playing a game by causing the slot machine 1 to erroneously detect the insertion of a medal by, for example, inserting a medal linked with a string and then pulling out the medal by pulling the string. .
On the other hand, by providing the upstream side detection sensor 23b, the downstream side detection sensor 23c, and the first CPU 44c that executes medal detection control, the slot machine 1 can prevent the game from proceeding due to illegal insertion of medals. .

  Specifically, when a medal is illegally inserted, a Lo level voltage signal is not input in the order of the upstream terminal 41a and the downstream terminal 41b, or Lo only to either the upstream terminal 41a or the downstream terminal 41b. Since the voltage signal of the level is input, the first microcomputer 44 can identify that it is not a normal medal insertion. Thereby, the slot machine 1 can detect the illegal insertion of medals and prevent the progress of the game.

  On the other hand, when the power supply voltage Vb becomes equal to or lower than the reference voltage, the power supply voltage monitoring circuit 27 can input a Lo level voltage signal to the downstream terminal 41b. That is, when the power supply voltage monitoring circuit 27 detects a voltage drop of the power supply voltage Vb, the Lo level voltage signal is input only to the downstream terminal 41b, so the slot machine 1 is controlled by the first CPU 44c that executes the medal detection control. Error actions can be performed.

  Thereby, the slot machine 1 can implement the detection of the driving machine and the detection of unauthorized insertion of medals with the same program. Therefore, the slot machine 1 can suppress the data size of the program that implements the first CPU 44c that executes the medal detection control, and can prevent the limited storage capacity of the first microcomputer 44 from being compressed.

  Therefore, the slot machine 1 uses the power supply voltage monitoring circuit 27 that inputs the Lo level voltage signal to the downstream terminal 41b, thereby detecting illegal acts using the driving machine and detecting illegal insertion of medals. Can be achieved while suppressing an increase in the number of parts.

  Further, when the power supply voltage Vb is equal to or lower than the reference voltage, the slot machine is configured to supply the Lo level voltage signal to the downstream terminal 41b for the output time T1 longer than the elapsed time T2. No. 1 can more reliably suppress an illegal act that provokes the gambling feeling of the player.

  Specifically, for example, when more medals than the maximum number that can be stored as credits are inserted, the slot machine 1 switches the medal selector 23 and returns the inserted medals to the player. When the medal selector 23 is switched, by setting an elapsed time T2 during which no error operation is performed, the slot machine 1 may cause an error due to detection of medals exceeding the upper limit even if the medal selector 23 is delayed. Is preventing.

  Therefore, for example, even if only the Lo level voltage signal output from the downstream detection sensor 23c is input during the elapsed time T2, the first CPU 44c that executes the medal detection control does not execute an error operation. . In other words, if the driving machine short-circuits the second power line PW2 during the elapsed time T2, the slot machine 1 may advance the game.

Therefore, during the output time T1 longer than the elapsed time T2, the first CPU 44c that executes the medal detection control by the power supply voltage monitoring circuit 27 that inputs the Lo level voltage signal to the downstream terminal 41b performs the first operation during the elapsed time T2. Even when the two power lines PW2 are short-circuited, the error operation can be reliably performed.
Therefore, the slot machine 1 can surely detect a short circuit of the second power line PW2, and can more reliably suppress an illegal act that instigates the player's joy.

  Further, the slot machine 1 is configured to input the Lo level voltage signal from the power supply voltage monitoring circuit 27 to the downstream terminal 41b via the pattern wiring 26a connected to the sensor signal line SL7. By suppressing the increase, it is possible to suppress fraudulent acts that provoke the player's happiness.

  Specifically, a transmission unit that transmits a Lo level voltage signal from the power supply voltage monitoring circuit 27 to the first microcomputer 44, and a transmission unit that transmits a Lo level voltage signal from the downstream detection sensor 23c to the first microcomputer 44. Therefore, the slot machine 1 can reduce the number of parts such as terminals, connectors, and signal lines.

  Furthermore, since the Lo-level voltage signal from the power supply voltage monitoring circuit 27 can be input to the downstream terminal 41b via the pattern wiring 26a connected to the sensor signal line SL7, the slot machine 1 has the number of parts on the game control board 41. In addition, it is possible to suppress an increase in the number of circuit patterns and a complication of a program for realizing medal detection control.

  Therefore, the slot machine 1 is configured to input the Lo level voltage signal from the power supply voltage monitoring circuit 27 to the downstream terminal 41b via the pattern wiring 26a connected to the sensor signal line SL7, thereby reducing the number of parts. By suppressing the increase, it is possible to suppress fraudulent acts that provoke the player's happiness.

  In the present embodiment, the maximum bet switch 15, the bet switch 16, the stop switch 17, and the start switch 18 are configured by operation detection sensors that detect the player's operation in a non-contact manner, but the present invention is not limited thereto. As long as the power supply is received from the connection board 26 via each power line and a signal indicating that the player's operation is detected is transmitted to the game control device 40 via the signal line and the connection board 26, An appropriate operation detection sensor may be used.

  Further, although the upstream detection sensor 23b and the downstream detection sensor 23c configured separately are used as the medium detection sensors for detecting the flow of the medal, the upstream detection sensor 23b and the downstream detection sensor are not limited thereto. It is good also as a medium detection sensor which constituted sensor 23c integrally. Or it is good also as a medium detection sensor comprised with one sensor, a medium detection sensor which identifies the authenticity of a medal, a medium detection sensor which combined these, etc.

Further, the power supply connection board 33b that distributes the controlled power to the first power line PW1 and the second power line PW2 is provided inside the power supply unit 33. However, the present invention is not limited to this, and the power supply connection board 33b is provided outside the power supply unit 33. You may prepare for.
In addition, the power supply unit 33 is connected to the first power line PW1 and the second power line PW2. However, the present invention is not limited to this, and the power supply unit to which the first power line PW1 is connected and the power supply to which the second power line PW2 is connected. Units may be different.

Further, the maximum bet switch 15, the bet switch 16, the stop switch 17, the start switch 18, the upstream side detection sensor 23b, the downstream side detection sensor 23c, and the connection board 26 are connected to each other by signal lines. Instead, they may be connected by optical communication or wireless .
Also, the maximum BET switch 15, bet switch 16, stop switch 17, a start switch 18, connected upstream sensor 23b, and the downstream sensor 23c, the gaming control board 41 via the respective signal lines and the connection substrate 26 However, the present invention is not limited to this, and the game control board 41 may be directly connected via each signal line.

  Further, although the first microcomputer 44 and the second microcomputer 54 have been described as the control means, the present invention is not limited to this, and the CPU, RAM, and ROM are provided on the control board, respectively. It is good also as a control means of the structure which controls operation | movement by cooperation.

  In addition, the Lo level voltage signal from the power supply voltage monitoring circuit 27 is input to the downstream terminal 41b via the pattern wiring 26a connected to the sensor signal line SL7. However, the present invention is not limited to this, and the power supply voltage monitoring is performed. Any configuration can be used as long as the voltage signal from the circuit 27 can be input to the game control device 40. For example, a signal line for connecting the power supply voltage monitoring circuit 27 and the game control device 40 is provided separately, and a voltage signal from the power supply voltage monitoring circuit 27 is supplied to the game control device 40 via the signal line provided separately. It is good also as a structure made to input.

Further, outputs a Hi-level voltage signal when not detecting a medal, upstream sensor 23b that outputs a Lo level voltage signal when detecting a medal, and has been the downstream sensor 23c, which but not limited to, it outputs a Lo level voltage signal when not detecting a medal, upstream sensor 23b that outputs a voltage signal of Hi level when it detects the medal, and also as a downstream side sensor 23c Good.

  Further, when the Lo level voltage signal is input to the upstream terminal 41a or the downstream terminal 41b while the solenoid 23a is on, the Lo level voltage signal is input in the order of the upstream terminal 41a and the downstream terminal 41b. However, the present invention is not limited to this, but any configuration can be used as long as it can determine that a Lo level voltage signal has been input in the order of the upstream terminal 41a and the downstream terminal 41b. The control operation may be configured as follows.

  Further, the power supply voltage monitoring circuit 27 is configured by the transistor Q and the pulse generation circuit 27a. However, the present invention is not limited to this, and it is driven by the power supply voltage Va and a voltage signal is triggered by the voltage drop of the power supply voltage Vb. As long as the circuit can input to 40, an appropriate configuration may be adopted. Furthermore, a voltage detection unit having an appropriate configuration capable of detecting the voltage of the power supply voltage Vb may be connected to the trigger terminal of the pulse generation circuit 27a.

  Although the power supply voltage monitoring circuit 27 includes the pulse generation circuit 27a, the power supply voltage monitoring circuit 27 includes a comparator circuit instead of the pulse generation circuit 27a. More specifically, for example, when the transformed power supply voltage Va is input as a reference voltage and the power supply voltage Vb is input and the power supply voltage Vb exceeds the reference voltage, a Lo level voltage signal is output, and the power supply voltage Vb is When the voltage is equal to or lower than the reference voltage, the comparator circuit outputs a Hi level voltage signal. Then, based on the voltage signal output from the comparator circuit, the power supply voltage monitoring circuit 27 in which the switching element such as the transistor Q is turned on during the output time T1 may be used.

  In the medal detection control of FIG. 7, when a Lo level voltage signal is input to the downstream side terminal 41b (step S102: Yes), or the Lo level voltage signal is output in the order of the upstream side terminal 41a and the downstream side terminal 41b. When not input (step S105: No), the error operation of step S103 is executed. However, the present invention is not limited to this, and different error operations may be performed.

  For example, when the Lo level voltage signal is input to the downstream terminal 41b when the solenoid 32a is off (step S102: Yes), the first CPU 44c uses the driving machine to output the Lo level voltage signal to the downstream terminal 41b. Is displayed, and a warning screen is displayed on the liquid crystal monitor 12 to prohibit the use of the driving machine.

  On the other hand, when the solenoid 32a is in the ON state and the Lo level voltage signal is not input in the order of the upstream terminal 41a and the downstream terminal 41b (step S105: No), the first CPU 44c makes an erroneous detection of the insertion of a medal. It may be determined that an illegal act has occurred, and a warning screen for prohibiting an illegal act of counting medals may be displayed on the liquid crystal monitor 12.

Further, although the power supply voltage monitoring circuit 27 for monitoring the power supply voltage Vb applied to the connection substrate 26 is used, the present invention is not limited to this, and the power supply voltage Vb applied to the start switch 18 may be monitored.
As a result, when the driving machine short-circuits the power supply line PL4 for applying the power supply voltage Vb to the start switch 18, the power supply voltage monitoring circuit 27 detects the voltage drop of the power supply voltage Vb and outputs the Lo level voltage signal. The data can be input to the downstream terminal 41b.

  For this reason, even when a voltage signal is output from the start switch 18 by the driving machine, the slot machine 1 can prevent the start of the internal lottery in the first microcomputer 44 by the power supply voltage monitoring circuit 27. Unauthorized actions such as setting the state immediately before the jackpot can be suppressed.

  Therefore, in the slot machine 1, the power supply voltage monitoring circuit 27 that monitors the power supply voltage Vb applied to the start switch 18 is used to suppress an illegal act that instigates the player's gambling and ensure the fairness of the game. can do.
