Description

  The present invention relates to a gaming machine configured with a computer circuit, and more particularly to a gaming machine having a structure that can effectively eliminate fraudulent games.

  A ball and ball game machine such as a pachinko machine has a symbol start port provided on the game board, a symbol display unit for displaying a series of symbol variation modes such as stopping a plurality of display symbols after varying a predetermined time, and an opening / closing plate It is configured with a grand prize opening that opens and closes. When the detection switch provided at the symbol start port detects the passing of the game ball, the game ball enters a winning state, and after the game ball is paid out as a prize ball, the symbol display unit changes the display symbol for a predetermined time. Thereafter, when the symbol stops in a predetermined manner such as 7-7-7, a big hit state is established, and the big winning opening is repeatedly opened to generate a profit state advantageous to the player.

  Whether or not to enter the big hit state is determined based on, for example, a random number value at the time of winning when the game ball passes through the symbol start opening. That is, when a predetermined winning state is generated in relation to the player's gaming operation, it is determined whether or not to generate a profit state advantageous to the player by a lottery determination using a random value resulting therefrom.

  Therefore, an unauthorized player opens the gaming machine using a joint key or the like, or creates a gap between the frame body and the door body, from which foreign objects such as piano wire and celluloid board enter, There is concern about illegal acts that illegally win a large number of game balls in other winning holes. This is because not only a large amount of winning balls can be obtained by illegally winning a large number of game balls, but also the chance of hitting a big hit will be probabilistically approached when winning at the symbol start opening.

  Further, in a spinning machine such as a slot machine, a large amount of game medals to be paid out to a player according to the game state is stocked inside the game machine body. Therefore, an unauthorized player opens a gaming machine using a joint key or the like, or creates a gap between the frame body and the door body, from which foreign objects such as a piano wire and a celluloid board enter to play a game regardless of winning a prize. There is concern about illegal acts that illegally attempt to obtain a large number of game medals stocked inside the machine.

  Therefore, in order to eliminate such illegal actions, a conventional gaming machine has a mechanical switching contact SW on the gaming machine body corresponding to the opening / closing door GT (see FIG. 8). When the open / close door GT is opened, for example, the open / close contact SW that has been in an ON state is changed to an OFF state, and this change is detected by an electronic circuit.

  However, since the conventional gaming machine uses a simple opening / closing contact, for example, by sliding a thin plate into the gap between the opening / closing door GT and the gaming machine main body, the opening / closing door GT is maintained while the ON / OFF contact state is maintained. It is also possible to open the game, which may prevent illegal games.

However, nothing has been proposed about measures that can effectively prevent such illegal games. Although a circuit configuration using a comparator has been proposed (Patent Document 1), the technique described here is not directly related to the above-described problems.

Here, the term “resistor” is a concept that includes not only a normal resistance as an electronic element but also a resistance having a resistance value of 0Ω in a short-circuit state.

  The present invention is effective when used in a gaming machine that determines whether or not a profit state advantageous to a player is generated by a lottery determination resulting from the occurrence of a predetermined winning state related to the operation of the player. In particular, it is suitable for use in a ball game machine.

  The connector is preferably composed of a male member and a female member. In this case, the female member preferably has a movable contact that can be elastically deformed.

  The other two contacts are supplied with a DC voltage to one inspection voltage contact, while the other signal input contacts are connected to two comparison circuits. Is enough. Here, the two comparison circuits are configured to compare the voltage SG of the signal input contact with the two comparison reference voltages E1 and E2 and output two binary signals according to the comparison result. Is effective. In particular, the voltage SG of the signal input contact when the door is closed is preferably set to an intermediate value (E1 <SG <E2) between the comparison reference voltages E1 and E2 of the two comparison circuits. Further, two binary signals output from the two comparison circuits are supplied to a logic circuit, and a simple detection signal indicating whether or not the door is in a closed state is generated.

The chance button 11 is provided at a position where it can be operated with the left hand of the player, and the player can operate the chance button 11 without releasing the right hand from the firing handle 10. The chance button 11 does not function normally, but when the game state becomes the button chance state, the built-in lamp is turned on and can be operated. The button chance state is a game state provided as necessary.

  On the right side of the upper plate 8, an operation panel 12 for ball lending operation with respect to the card-type ball lending machine is provided, a frequency display unit for displaying the remaining amount of the card with a three-digit number, and a ball of game balls for a predetermined amount A ball lending switch for instructing lending and a return switch for instructing to return the card at the end of the game are provided.

  A key hole HO for opening the gaming machine is provided on the right side of the upper plate 8. The door 6 is configured to be opened from the front frame 3 when the key is inserted into the keyhole HO and rotated slightly in the clockwise direction (FIG. 2). Further, when the key inserted into the keyhole HO is rotated largely, the front frame 3 is released from the outer frame 1. In the open state of the front frame 3, the game board 5 and the control boards 20 to 26 are integrally opened with the front frame 3.

  As shown in FIG. 3, the game board 5 is provided with a guide rail 13 formed of a metal outer rail and an inner rail in an annular shape, and a liquid crystal color display DISP is provided at the approximate center of the game area 5a inside. Has been placed. In addition, at a suitable place in the game area 5a, a symbol starting port 15, a big winning port 16, a plurality of normal winning ports 17 (four on the right and left sides of the big winning port 16), and a gate 18 serving as two passing ports are arranged. Has been. Each of these winning openings 15 to 18 has a detection switch inside, and can detect the passage of a game ball.

  The liquid crystal display DISP is a device that variably displays a specific symbol related to a big hit state and displays a background image and various characters in an animated manner. This liquid crystal display DISP has special symbol display portions Da to Dc in the center portion and a normal symbol display portion 19 in the upper right portion. The special symbol display portions Da to Dc execute a reach effect that expects a big hit state to be invited, and the special symbol display portions Da to Dc and the surroundings perform a notice effect that informs the result of the determination indefinitely. The

  The normal symbol display unit 19 displays a normal symbol. When a game ball that has passed through the gate 18 is detected, the displayed normal symbol fluctuates for a predetermined time and is extracted at the time when the game ball passes through the gate 18. The stop symbol determined by the random number for lottery is displayed and stopped.

  For example, the symbol start opening 15 is configured to be opened and closed by an electric tulip having a pair of left and right opening and closing claws 15a. When the stop symbol after the fluctuation of the normal symbol display unit 19 displays a winning symbol, the symbol starting port 15 is opened and closed The claw 15a is opened for a predetermined time. When a game ball wins the symbol start port 15, the display symbols of the special symbol display portions Da to Dc change for a predetermined time and are determined based on the lottery result corresponding to the winning timing of the game ball to the symbol start port 15. Stop at the stop symbol. In addition, in special symbol display parts Da-Dc and its circumference, a notice effect may be performed between a series of symbol effects.

  The big winning opening 16 is controlled to open and close by, for example, an opening / closing plate 16a that can be opened forward.

A winning area 16 b is provided inside the big winning opening 16.

  After the opening / closing plate 16a of the big prize opening 16 is opened, the opening / closing plate 16a is closed when a predetermined time elapses or when a predetermined number (for example, 10) of game balls wins. In such an operation, the special game is continued up to 15 times, for example, and is controlled in a state advantageous to the player. In addition, when the stop symbol after the change of the special symbol display parts Da to Dc is a specific symbol of the special symbols, a privilege that the game after the end of the special game is in a high probability state is given. Usually, the big hit by this specific design is called “probable big hit”.

  FIG. 4 is a block diagram showing an overall circuit configuration of the pachinko machine 1 that realizes each operation described above. Broken lines in the figure mainly indicate DC voltage lines.

  As shown in the figure, this pachinko machine 1 receives AC 24V, outputs various DC voltages (5V, 12V, 32V, BU) and outputs a system reset signal SYS when the power is turned on, and a game operation. Main control board 21 to be controlled automatically, effect control board 22 that executes lamp effect and sound effect based on control command CMD received from main control board 21, and a signal received from effect control board 22 is transmitted to each part. The production interface board 23, the liquid crystal control board 24 that drives the liquid crystal display DISP based on the control command CMD ′ received from the production interface board 23, and the payout motor M based on the control command CMD ″ received from the main control board 21. A payout control board 25 for controlling and paying out a game ball, and issuing a game ball in response to a player's operation. It is organized around a firing control board 26 for.

  Here, the main control board 21, the effect control board 22, the liquid crystal control board 24, and the payout control board 25 are each mounted with a computer circuit including a one-chip microcomputer. Therefore, the functions mounted on the main control board 21, the production control board 22, the liquid crystal control board 24, and the payout control board 25 and the operations realized by the circuits are functionally named. Unit 21, effect control unit 22, liquid crystal control unit 24, and payout control unit 25. All or part of the effect control unit 22, the liquid crystal control unit 24, and the payout control unit 25 are sub-control units.

  FIG. 5 is a block diagram showing an internal configuration of the power supply board 20. As illustrated, the power supply substrate 20 includes three full-wave rectifier circuits 40 to 42 that convert AC 24 V into pulsating voltage (DC 24 V), and smoothing circuits 43 a to 43 d that smooth the output voltages of the full-wave rectifier circuits 40 and 41. A stabilized power supply circuit 44a to 44c using a three-terminal regulator, a backup power supply circuit 45 that maintains a DC voltage of 5V even after the power supply is cut off, and a full-wave rectifier circuit 40 when the DC output voltage (12V, 5V) rises abnormally. The forcible cut-off circuit 46 for short-circuiting the output and a power reset circuit (not shown) using a dedicated IC are included.

  As shown in FIG. 4, the main control board 21 receives a power supply abnormality signal ABN output from the power supply board 20 in addition to DC12V, DC32V, and backup power supply BU (= DC5V) (see FIG. 4), A system reset signal SYS output at power-on is received. In the main control board 21, the received DC 12V is stepped down to DC 5V, and used as the power supply voltage of the computer circuit in the board.

  The main control board 21 is connected to the command relay board 29 and is connected to each game component of the game board 5 via the game board relay board 27. And while receiving the switch signal of the detection switch built in each winning opening 16-18 on a game board, solenoids, such as an electric tulip, are driven. Note that the switch signal from the symbol start port 15 is received directly by the main control unit 21 without going through the game board relay board 27.

  The payout control unit 25 outputs a power supply abnormality signal ABN that is output when the voltage drops, and a power supply abnormality signal ABN that is output when the power is turned on, in addition to DC12V, AC24V, and backup power supply BU (= DC5V). System reset signal SYS is received. In the payout control board 20 as well, the received DC12V is stepped down to DC5V to be the power supply voltage of the computer circuit in the board. In this way, the payout control unit 25 and the main control unit 21 do not receive the direct-current power supply voltage 5V directly from the power supply board 20, so the high-frequency power is supplied from the other control boards 25, 23, 22, 24 through the DC5V power supply line. The risk of receiving noise is avoided.

  The payout control unit 25 performs a function of paying out a prize ball designated based on the control command CMD ″ received from the main control unit 21. Specifically, the payout control unit 25 is required by rotating the payout motor M1 a predetermined number of times. A prize ball counting signal indicating a game ball payout operation and a status signal CON relating to an abnormality in the payout operation are transmitted to the main controller 21. The status signal CON Includes, for example, an out-of-supply signal, an insufficient payout error signal, and a lower plate full signal.

  The payout control unit 25 outputs an AC voltage AC24V and a launch control signal CTL to the launch control board 26. The launch control signal CTL is a condition for operating the launch motor M2. When the launch control signal CTL is at L level, the launch operation of the game ball is prohibited.

  Further, the payout control unit 25 outputs a prize ball signal and a door signal DR to the hall computer. The hall computer is a computer device that centrally manages all the gaming machines in the gaming hall, and manages the winning ball operation of the payout motor M1 based on the winning ball signal received from each gaming machine. On the other hand, the door signal DR is a signal indicating that the glass door 6 has been opened, and it is possible to manage that the clerk has opened the glass door 6 in the event of an abnormality such as a game ball clogging a game member.

FIG. 6 is a plan view showing a male connector CN _m and a female connector CN _f for generating the door signal DR. The door signal DR is generated depending on whether or not the female connector CN _f and the male connector CN _m shown in the figure are fitted. In this embodiment, the male connector CN _m to which the detection resistor R1 is connected is the glass door 6. The female connector CN _f that is disposed inside the cable and is cable-connected to the payout control unit 25 is disposed on the front frame 3 (see FIG. 2).

As shown in FIG. 6C, the female connector CN _f of the embodiment is configured by connecting a plurality of movable contacts, and the left and right movable contact groups are arranged with a ½ pitch shift from each other. . Corresponding to this configuration, in the male connector CN _m , the left and right fixed contact groups are shifted from each other by ½ pitch so as to contact the movable contact group.

The movable contact is made of a conductive metal having spring elasticity. When the male connector CN _m enters and fits into the female connector CN _f , the movable contact is bent and deformed so that the two are surely in contact with each other. Thus, in this door connector CN, since the movable contact has spring elasticity, the contact is not worn even when the connector is attached or detached, and the connector can be used repeatedly (10,000 times or more even at the minimum guaranteed value).

FIG. 7 illustrates electronic circuits associated with male and female connectors CN _m and CN _f . As shown, between two fixed contacts of the male connector CN _m, the detection resistor R1 is connected (see FIG. 6 (a)). Further, the one movable contact of the female connector CN _f is supplied with power supply voltage Vcc from the payout controller 25, the other movable contact being connected to the earth line payout controller 25 through the voltage dividing resistors R2 ing.

Therefore, when the male and female connectors CN _m and CN _f are fitted, the detection voltage SG, which is the voltage across the voltage dividing resistor R2, is SG = R2 / (R1 + R2) × Vcc. On the other hand, when the connector CN is not fitted, the detection voltage SG is SG = 0.

  This detection voltage SG is supplied to the inverting terminals (−) of the two comparators COM1 and COM2. On the other hand, comparison reference voltages E1 and E2 are supplied to the non-inverting terminal (+) of each comparator. Here, the comparison reference voltages E1 and E2 have a relationship of E1 <E2 and are set to close values (E2−E1 = about 0.5 to 1.0 V).

  Thus, in this embodiment, since the comparison reference voltage has a relationship of E1 <E2, when SG <E1, both the output Q1 of the comparator COM1 and the output Q2 of the COM2 are at the H level. When E1 <SG <E2, the output Q1 of the comparator COM1 is L level and the output Q2 of COM2 is H level. Further, when E2 <SG, the output Q1 of the comparator COM1 and the output Q2 of the COM2 are both at the L level.

  As shown in FIG. 2, when the glass door 6 is opened, the connector CN is in a non-fitted state, so that the detection voltage SG becomes 0, and both the output Q1 of the comparator COM1 and the output Q2 of the COM2 are at the H level. Become. On the other hand, when the glass door 6 is closed, the connector CN is in a fitted state, so that the detection voltage SG is SG = R2 / (R1 + R2) × Vcc. Therefore, in this embodiment, the opening / closing of the glass door 6 is detected by setting E1 <R2 / (R1 + R2) × Vcc <E2. That is, when the glass door 6 is closed, Q1 = L level and Q2 = H level. When the glass door 6 is open, Q1 = H level and Q2 = H level. It becomes possible to grasp the open / closed state of the door 6.

  As shown in FIG. 7, the output Q1 of the comparator COM1 is connected to the AND gate G1 via the NOT gate, and the output Q2 of the COM2 is directly connected to the AND gate G1. Therefore, the output of the AND gate becomes H level only when Q1 = L level and Q2 = H level, that is, when the glass door 6 is closed, and otherwise becomes L level.

  Since the output of the AND gate G1 is logically inverted by the sink driver and becomes the door signal DR, the door signal becomes the L level only when the glass door 6 is closed, and the glass door 6 is opened or other. It becomes H level in the abnormal state. Therefore, the hall computer only needs to detect the rising timing of the door signal DR. Therefore, in this embodiment, the rising of the door signal DR is detected and the time is recorded.

  For example, even if an unauthorized player illegally opens the glass door 6 using a key or the like to illegally win a game ball, the door signal DR rises at the moment when the glass door 6 is opened, and the time is recorded. As a result, the staff can be dispatched immediately.

  Thus, in this embodiment, the connector CN connected to the detection resistor R1 is used instead of a simple contact switch, so that the glass door 6 is opened without changing the door signal DR as in the conventional gaming machine. It becomes impossible. Even if the resistor R1 is connected between the corresponding fixed contacts of the male connector immediately after the glass door 6 is opened, the door signal rises for a moment, so that an illegal act can be detected. Moreover, since the comparison reference voltages E1 and E2 have a relationship of E2> E1 and are set to close values, if a resistance value different from the resistance R1 is connected between the fixed contacts, the door signal DR is H Continue to notify the open state at the level. This is the same even if the fixed contacts are short-circuited.

  In the embodiment of FIG. 7, the output of the AND gate G1 is transmitted as a door signal DR to the hall computer. However, the 2-bit door signal DR obtained by adding the output Q2 of the comparator COM2 to the output of the AND gate G1. May be sent to the hall computer. For example, in such a case, the hall computer that has received the signal of the output Q2 = L level can grasp that an abnormal situation other than the opening of the door has occurred.

  Although the embodiments of the present invention have been specifically described above, the specific description content is not intended to limit the present invention, and various modifications can be made. For example, although the glass door 6 has been described in the embodiment, it is also effective to provide a male and female connector CN of the same type between the front frame 3 and the outer frame 1.

  In addition, the arrangement position of the connector can be freely set including which of the male and female connectors is arranged on the door. That is, in the embodiment, the male and female connectors are provided close to the hinge of the open / close door, but conversely, the connector may be arranged at a distance R by being far away from the hinge. In this case, even if the opening angle θ of the open / close door is small, the movement amount Rθ in the connector portion is large, so it is not possible to create a gap by slightly opening the gaming machine without separating the male and female connectors from each other. Can not. In addition, the circuit configuration and circuit elements specifically exemplified can be changed as appropriate. For example, although the detection resistor R1 is used in the embodiment, instead, the corresponding contact of the male connector may be short-circuited so that R1 = 0. However, in this case, the security level is inferior to that in the embodiment.

  In addition, as a process when it is detected that the open / close door is opened, not only is it notified to the hall computer, but in addition to this, for example, (1) corresponding to the level change of the door signal DR (detection signal) It is effective to take measures such as immediately prohibiting the award ball payout operation and / or (2) flashing the door open status using voice, lamp, or liquid crystal display. . In the case of adopting such an embodiment, the resumption of the payout operation is executed by operating a release button by a hall clerk. Note that the release button is provided, for example, on the payout control board.
