Description

  The present invention relates to a gaming machine provided with various detection switches for detecting that a game ball has won or passed.

  Conventional gaming machines are provided with a regular winning opening, a starting opening, a gate, a big winning opening, etc. on a gaming board in which a gaming area is formed. Are provided with various detection switches for detecting whether or not the game ball has won or passed (in such a conventional gaming machine, there are four normal winning ports, one start port, and two gates). , And many have one big prize opening).

  When the game ball wins or passes through the normal winning opening, the starting opening and the gate, a signal to that effect is input to the main control board. The main control board controls the progress of the game based on these detection signals. For example, when a game ball wins a start opening, a detection signal detected by a detection switch is input to the main control board, and the main control board is in a special gaming state (big hit) that is advantageous to the player when a predetermined condition is satisfied. State). In this special game state, the main control board performs control to open the big winning opening so that the game ball wins. Then, when a game ball wins the grand prize opening, a detection signal detected by the detection switch is inputted to the main control board, and the main control board counts the game balls won in the big prize opening by this detection signal and closes it. When the condition is satisfied, the control for closing the special winning opening is performed again.

  In this way, the game board is provided with a plurality of detection switches, and these detection switches include electromagnetic (non-contact) proximity switches that electrically detect winning or passing of game balls, There is a mechanical (contact type) mechanical switch that is detected by an ON / OFF operation of the switch. While this mechanical switch is less expensive than a proximity switch, its life is determined by the number of operations because the detection method is a contact type, and its life is shorter than that of a non-contact type proximity switch.

  In order to maintain game play, the above-described obstacle nails around the normal winning opening are adjusted to return the game ball to the player to some extent, but the frequency at which the game ball wins the normal winning opening is never high. On the other hand, the start opening and gate described above have a higher frequency of winning or passing than the normal winning opening, and determine the progress of the game. Further, in the above-mentioned big hit state, the big winning opening is opened, so that the frequency of game balls to be won in the big winning opening is higher than that in the normal winning opening. Thus, at the start opening, the gate, and the big winning opening in the big hit state, detection of winning or passing of the game ball frequently occurs.

  For this reason, when considering the period of use (life cycle) from installation to disposal of gaming machines, detection switches used for start openings, gates, and prize winning openings are required to have a long life, and the above-described operation Mechanical switches whose life is determined by the number of times are not suitable.

By the way, in order to increase the variation of the game so that the game does not become monotonous, various types having a plurality of the above-described start opening or big winning opening have been proposed. For example, one start port is provided on each of the left and right sides, and when a game ball wins in each of these start ports, the display pattern displayed on the screen of the liquid crystal unit differs depending on the winning start port (for example, , Patent Document 1), and one prize winning opening is provided below the start opening and one obliquely below the right side of the liquid crystal display, respectively, and when the big hit state is reached, the two prize winning openings are opened simultaneously, There have been proposed ones (for example, Patent Document 2) that open a large winning opening where a game ball has been won first under a predetermined opening condition.
Japanese Patent Laying-Open No. 2003-230711 (FIG. 6) Japanese Patent Laying-Open No. 2005-211230 (FIG. 5)

  However, if the number of normal winning openings, starting openings, gates and special winning openings is changed according to the specifications of the gaming machine, such as when the number of starting openings and big winning openings described above increases, Since the number is changed, it is necessary to change the design of the input circuit for the detection switch provided on the main control board that controls the progress of the game in response to a signal from the detection switch provided on the game board. As described above, it is necessary to produce different main control boards for each specification of the gaming machine, which takes time and effort for development.

  Therefore, it is conceivable to share the main control board by fixing the number of signals received from the detection switches described above, that is, the number of inputs of the main control board. However, as described above, there is a problem that the number of detection switches for detecting the winning or passing of a ball game ball varies depending on the specifications of the gaming machine.

  The present invention has been made in view of such a problem in the case where the number of detection switches varies according to the specifications of the gaming machine, the purpose of which is, according to the specifications of the gaming machine, An object of the present invention is to provide a gaming machine that can use a common main control board even when a mechanical switch is used instead of a proximity switch.

The acoustic illumination device 29 includes a transparent cover body 35, a middle / high tone speaker 36, a speaker cover 37, a reflector body (not shown), and the like, and these constituent members are assembled together to form a unit.

  Next, the back surface configuration of the main body frame 3 will be described. As shown in FIG. 3, on the upper back side of the main body frame 3, a ball tank 140 that stores a game ball supplied from a ball lifting device installed on the game island, and a game ball stored in the ball tank 140. A tank rail 141 that flows down and a payout device 103 that takes in game balls flowing down along the tank rail 141 are arranged. The payout device 103 is formed in a unit shape and pays out a predetermined number of game balls based on a signal instructing payout of game balls.

  Below the tank rail 141, the above-described game board 4 is disposed. On the upper back side of the game board 4, a lamp drive board box 130 containing a lamp drive board described later, and a liquid crystal control board described later. And a liquid crystal control board box 132 containing a liquid crystal display, and a main control board box 134 containing a main control board and a sub board, which will be described later, is arranged below the back of the game board 4. A sub-integrated board box 136 containing a sub-integrated board, which will be described later, is disposed between the main control board box 134 and the back side of the game board 4, and the main integrated board box 136 is superposed on the sub-integrated board box 136. A control board box 134 is mounted.

  A board protection cover 142 that protects the lamp driving board box 130 and the liquid crystal control board box 132 is provided on the back side of the game board 4 so as to protrude from the back side of the pachinko machine 1. And the liquid crystal control board box 132 is covered.

Further, gradation lamps 49a and 49b whose luminance is adjusted (gradation control is performed) are attached below the rendering device 40 (below the display area 42).

  Below the stage device 40, there are provided a start winning opening 45 and an electric start winning opening 46 having a pair of opening and closing blades 47 below the starting winning opening 45. The electric start winning opening 46 includes an opening / closing blade solenoid 63 a that is a driving source for opening / closing the opening / closing blade 47. When the display result of the normal symbol display 50 is “winning”, the opening / closing blade 47 is opened for a predetermined time (for example, normal state: 0.5 seconds (s), or probability variation state: 3 s). To be controlled. It should be noted that a game ball from above can be won in the start winning opening 45, and the upper side is blocked by the start winning opening 45 in the electric start winning opening 46, and a game ball cannot be won if the open / close wing 47 is closed. It is in a state. For this reason, when the open / close wing 47 is in the open state, the game ball can be won.

  In addition, the game ball won in the start winning opening 45 is detected by the upper start opening switch 55a, while the game ball won in the electric start winning opening 46 is detected by the lower start opening switch 55b. Based on this detection (predetermined conditions are met), the special symbol display 41 performs special symbol variation display (decorative symbol variation display in the display area 42).

  When a game ball wins the start winning opening 45 or the electric start winning opening 46 and the game ball is detected by the upper start opening switch 55a or the lower start opening switch 55b, the display result of the special symbol on the special symbol display 41 is hit. A jackpot determination random number for determining whether or not to be (a specific display mode) is extracted. Also, if the winning winning opening 45 or the electric starting winning opening 46 is won during the change of the special symbol and the game ball is detected by the upper starting opening switch 55a or the lower starting opening switch 55b, the extracted big hit determination random number is predetermined. Up to the number (for example, 4) is stored. This stored number (starting stored number) is displayed by lighting a special-purpose memory lamp 54 composed of a plurality of light emitters (for example, four LEDs). The special figure storage lamp 54 is arranged at substantially the same position as the special symbol display 41.

  On the left side of the game area 12, a normal symbol display 50 is provided that variably displays a normal symbol by lighting and blinking of a light emitter (for example, LED). Also, a probability variation state lamp 51 that is turned on or off (in this embodiment, lighted in the probability variation state) is attached below the normal symbol display 50 depending on whether or not the gaming state is a probability variation state. Yes.

  In addition, on the left side and the right side below the rendering device 40, a left gate including a left gate switch 53a and a right gate including a right gate switch 53b are disposed. When the game ball is detected by the left gate switch 53a or the right gate switch 53b based on the game ball passing through the left gate or the right gate, the normal symbol display 50 starts to display the variation of the normal symbol. That is, the normal symbol variation display on the normal symbol display 50 is performed according to the detection of the game ball by the left gate switch 53a and the right gate switch 53b.

  When a game ball is detected by the left gate switch 53a and the right gate switch 53b, it is determined whether or not the normal symbol display result on the normal symbol display 50 is “winning”. Is extracted. Further, when the game ball passes the left gate or the right gate while the normal symbol changes, and the game ball is detected by the left gate switch 53a or the right gate switch 53b, the extracted random numbers for determining the normal symbol are a predetermined number ( For example, 4) are stored.

[5. Sub-board]

  Next, a sub-board for relaying detection signals from various switches to the main control board 101 will be described. 6 is a block diagram of the sub-board 105, and FIG. 7 is a block diagram of the sub-board 105 'having different specifications. As described above, the sub board 105 (105 ′) is housed in the main control board box 134 together with the main control board 101, and the sub board 105 (105 ′) and the main control board 101 are contained in the main control board box 134. The connector is connected with. In the present embodiment, the upper start port switch 55a, the lower start port switch 55b, the left gate switch 53a, the right gate switch 53b, and the count switch 64 described above are electrically detected electromagnetic (non-contact type). A proximity switch is used, and a mechanical (contact type) mechanical switch that is detected by an ON / OFF operation of the switch is used for the left winning port switch 57a and the right winning port switch 57b.

  As described above, a game ball won in the start winning opening 45 is detected by the upper start opening switch 55a, and a game ball won in the electric start winning opening 46 is detected by the lower start opening switch 55b and passed through the left gate. The ball is detected by the left gate switch 53a, the game ball that has passed through the right gate is detected by the right gate switch 53b, and the game ball that has won the big winning opening 61 is detected by the count switch 64, and the normal winning holes 66a and 66b are detected. A winning game ball is detected by the left winning port switch 57a, and a gaming ball winning the normal winning port 66c, 66d is detected by the right winning port switch 57b.

  At the electric start winning hole 46, the left gate and the right gate, the game balls are won or passed frequently, and the game balls are won by the upper start switch 55a, the lower start switch 55b, the left gate switch 53a and the right gate switch 53b. Or detection of passage occurs frequently. Therefore, long-life proximity switches are used as the upper start port switch 55a, the lower start port switch 55b, the left gate switch 53a, and the right gate switch 53b. Further, when the big hit state is reached, the big winning opening 61 is opened, the game ball is won, and the detection of the game ball by the count switch 64 occurs frequently. Therefore, a long-life proximity switch is used for the count switch 64 as well as the upper start port switch 55a, the lower start port switch 55b, the left gate switch 53a, and the right gate switch 53b.

  On the other hand, at the normal winning ports 66a to 66d, the frequency of winning the game balls is not high, and the detection of the winning of the game balls by the left winning port switch 57a and the right winning port switch 57b does not frequently occur. For this reason, a mechanical switch having a shorter life than the proximity switch is used for the left winning port switch 57a and the right winning port switch 57b.

  The detection signals detected by these left gate switch 53a, right gate switch 53b, upper start port switch 55a, lower start port switch 55b, count switch 64, left winning port switch 57a and right winning port switch 57b are shown in FIG. As shown, each input is made to the sub-board 105.

  The sub-board 105 includes a conversion circuit 105a and a pass line 105b, and the conversion circuit 105a includes a resistor R0 and a pull-down resistor R1. Detection signals from the left winning port switch 57a and the right winning port switch 57b, that is, detection signals from the mechanical switch are input to the main control board 101 via the conversion circuit 105a. On the other hand, the detection signal from the left gate switch 53a, the right gate switch 53b, the upper start port switch 55a, the lower start port switch 55b and the count switch 64, that is, the detection signal from the proximity switch is passed through the pass line 105b (conversion circuit). (Without going through 105 a)). The sub-board 105 is connected to a +12 volt (V) power line and a power ground (GND) line of the main control board 101, respectively.

  The main control board 101 includes a proximity switch input circuit 101c and a waveform shaping unit 200 in addition to the main control MPU 101a and the main control I / O port 101b described above. The proximity switch input circuit 101c includes a pull-up resistor R2 and a capacitor C0 as a low-pass filter (LPF). The detection signal from the proximity switch and the detection signal from the mechanical switch are used for the proximity switch. The signals are input to the waveform shaping unit 200 via the input circuit 101c. The waveform shaping unit 200 shapes the waveforms of various input detection signals, and transmits the shaped detection signals to the main control I / O port 101b. The waveform shaping unit 200 is connected to a + 12V power supply, a + 5V power supply, and a power supply GND, and a capacitor C1 as a decoupling capacitor is provided between the + 12V power supply and the power supply GND, and between the + 5V power supply and the power supply GND. It is connected.

  As described above, the detection switch input circuit of the mechanical switch and the proximity switch includes the conversion circuit 105a provided in the sub-board 105 and the proximity switch input circuit 101c provided in the main control board 101. In the circuit 105a, the voltage of the detection signal from the mechanical switch is converted to a voltage level input to the proximity switch input circuit 101c.

  Next, a pachinko machine 1 ′ having such a specification, which has an electric start winning opening 46 and a left gate, for example, not including the starting winning opening 45 and the right gate shown in FIG. 4 will be described. Since the main configuration of the pachinko machine 1 'is the same as that of the pachinko machine 1 described above, its description is omitted.

  Since the pachinko machine 1 ′ does not include the start winning opening 45 and the right gate, the upper start opening switch 55a and the right gate switch 53b described above are used as winning opening switches for detecting game balls that have won the normal winning openings 66a to 66d. Use.

  Specifically, the game balls won in the normal winning ports 66a and 66b are added to the left winning port switch 57a, and the upper start port switch 55a is used as the left winning port switch 55a ', while the normal winning ports 66c and 66d are used. In addition to the right winning port switch 57b, the right gate switch 53b is used as the right winning port switch 53b ′. That is, each of the normal winning ports 66a to 66d is provided with a detection switch (for example, the left winning port switch 55a 'for the normal winning port 66a, the left winning port switch 57a for the normal winning port 66b, and the normal winning port). The right winning port switch 57b is provided in the mouth 66c, and the right winning port switch 53b 'is provided in the normal winning port 66d).

  As described above, the start winning opening 45 provided with the upper start opening switch 55a and the right gate provided with the right gate switch 53b have a high frequency of winning or passing game balls, and the upper start opening switch 55a and Detection of winning or passing of a game ball by the right gate switch 53b frequently occurs. For this reason, long-life proximity switches are used as the upper start opening switch 55a and the right gate switch 53b. On the other hand, the regular winning ports 66a to 66d having the left winning port switch 57a and the right winning port switch 57b do not have a high frequency of winning game balls, and the winning of the game ball by the left winning port switch 57a and the right winning port switch 57b is not. Detection does not occur frequently. For this reason, a mechanical switch having a shorter life than the proximity switch is used for the left winning port switch 57a and the right winning port switch 57b.

  In the pachinko machine 1 described above, the game balls won in the normal winning ports 66a and 66b are detected by the left winning port switch 57a, and the game balls won in the normal winning ports 66c and 66d are detected by the right winning port switch 57b. However, in the pachinko machine 1 ′, the game ball won in the normal winning port 66a is detected by the left winning port switch 57a, and the game ball won in the normal winning port 66b is detected by the left winning port switch 55a ′. The game ball won in 66c is detected by the right winning port switch 57b, and the game ball won in the normal winning port 66d is detected by the right winning port switch 53b '.

  As described above, the mechanical switch is used as the detection switch for detecting the game ball won in the normal winning openings 66a to 66d. For this reason, the upper start port switch 55a, which is a proximity switch for detecting the game ball won in the start winning port 45 in the pachinko machine 1, is used as the left winning for detecting the game ball won in the normal winning port 66a in the pachinko machine 1 '. When used as the mouth switch 55a ′, the proximity switch is changed to a mechanical switch. Further, in the pachinko machine 1, a right gate switch 53b, which is a proximity switch that detects a game ball that has passed through the right gate, is used as a right winning port switch 53b ′ that detects a game ball that has passed through the normal winning hole 66d in the pachinko machine 1 ′. When used as a switch, the proximity switch is changed to a mechanical switch. In this case, as shown in FIG. 7, the detection signals from the left winning opening switches 55a 'and 57a and the right winning opening switches 53b' and 57b, that is, the detection signals from the mechanical switches are sent to the main control via the conversion circuit 105a. Input to the substrate 101. On the other hand, detection signals from the left gate switch 53a, the lower start port switch 55b, and the count switch 64, that is, detection signals from the proximity switch, are transmitted to the main control board 101 via the passage line 105b (not via the conversion circuit 105a). Entered.

  Thus, according to the specifications of the pachinko machine, even if the number of proximity switches changes, the sum of the number of proximity switches and the number of mechanical switches is always a fixed value (7 in this embodiment). The number of mechanical switches is increased or decreased. That is, the number of detection signals input to the main control board 101 is always fixed by compensating for the increase / decrease of the proximity switch due to the specifications of the pachinko machine by the number of mechanical switches.

  When using a mechanical switch instead of a proximity switch, as shown in FIG. 7, a sub-board 105 ′ having a conversion circuit 105a may be created according to the number of mechanical switches, depending on the specifications of the pachinko machine. This eliminates the need to recreate the main control board 101. Therefore, in accordance with various specifications of the pachinko machine, the common main control board 101 can be used even when a mechanical switch is used instead of the proximity switch.

The number of proximity switches and the number of mechanical switches shown in FIGS. 6 and 7 are set so as to satisfy the relationships of the following formulas (1) to (3).
(formula)
M = L−N (1)
1 ≦ M ≦ F (2)
1 ≦ N ≦ L−F (3)
(However, F: number of normal winning openings (pieces), N: number of proximity switches (pieces), M: number of mechanical switches (pieces), L: number of proximity switch input circuits provided on the main control board 101 ( ))

  Specifically, in the pachinko machine 1, the number F of the normal winning holes is four by the normal winning holes 66a to 66d, and the number N of the proximity switches is the left gate switch 53a, the right gate switch 53b, and the upper start. By the mouth switch 55a, the lower start port switch 55b, and the count switch 64, there are five, and as shown in FIG. 6, the number L of proximity switch input circuits is seven. Here, since the number N of the proximity switches is 5, the above-described formula (2), that is, 1 or more and 3 (= L−F = 7−4) or less is satisfied. Therefore, in the pachinko machine 1, the number M of the mechanical switches for winning the normal winning ports 66a to 66d shown in FIG. 4 is the above-described formula (1), that is, M = 7-5 = 2 (pieces). Here, since the number M of the mechanical switches is 2, the above-described expression (3), that is, 1 or more and 4 (= F) or less is satisfied. In this way, by setting the number M of mechanical switches, the game balls won in the normal winning ports 66a and 66b are detected by the left winning port switch 57a, and the game balls won in the normal winning ports 66c and 66d are It is detected by the winning opening switch 57b.

  On the other hand, in the pachinko machine 1 ′, as described above, the number F of the normal winning ports is four by the normal winning ports 66a to 66d, and the number N of the proximity switches is the left gate switch 53a, the lower start port switch. 55b and the count switch 64, and the number L of the proximity switch input circuits is seven as shown in FIG. Here, since the number N of the proximity switches is 3, the above-described formula (2), that is, 1 or more and 3 (= L−F = 7−4) or less is satisfied. Therefore, in the pachinko machine 1 ′, the number M of mechanical switches for winning the normal winning ports 66 a to 66 d is the above-described formula (1), that is, M = 7−3 = 4 (pieces). Here, since the number M of the mechanical switches is 4, the above-described expression (3), that is, 1 or more and 4 (= F) or less is satisfied. In this way, by setting the number M of mechanical switches, the game ball won in the normal winning port 66a is detected by the left winning port switch 55a ', and the game ball won in the normal winning port 66b is detected by the left winning port switch. The game ball detected by 57a and won in the normal winning port 66c is detected by the right winning port switch 57b, and the game ball won in the normal winning port 66d is detected by the right winning port switch 53b '.

  According to the pachinko machine 1 of the present embodiment described above, the left gate switch 53a, the right gate switch 53b, and the upper start opening switch 55a that detect winning or passing of a game ball in the game area 12 formed on the game board 4 are detected. Further, proximity switches such as the lower start port switch 55b and the count switch 64 and mechanical switches such as the left winning port switch 57a and the right winning port switch 57b are mixed.

  The mechanical switch is a contact type mechanical detection switch, and is provided in the normal winning holes 66a to 66d, and detects that the game ball has won. The proximity switch is a non-contact type electromagnetic detection switch, which is provided at each of the left gate, the right gate, the start winning port 45, the electric start winning port 46, and the big winning port 61, and indicates that the game ball has passed or won. To detect.

  The main control board 101 includes a proximity switch input circuit 101c to which a detection signal from the proximity switch is input, and controls the progress of the game based on the detection signal. The sub board 105 outputs the detection signal from the proximity switch to the main control board 101, while converting the detection signal from the mechanical switch into a voltage level input to the proximity switch input circuit 101c, 101 is provided with a conversion circuit 105 a that outputs the data to 101. In this way, the detection signal from the mechanical switch is converted by the sub-board 105 so that the voltage level of the detection signal from the proximity switch is at a level. Therefore, according to the specifications of the pachinko machine, the mechanical switch is replaced with the proximity switch. Even if it is used, the common main control board 101 can be used.

  Further, in the main control board box 134, the sub board 105 and the main control board 101 are accommodated in a connector connection. In order to transmit the detection signal that affects the game result to the main control board 101, the sub board 105 accommodates the sub board 105 and the main control board 101 in the main control board box 134, thereby preventing illegal connection between the connectors. Can be prevented.

  Furthermore, the number of proximity switches and the number of mechanical switches mixed in the pachinko machine 1 and the pachinko machine 1 ′ are set so that the predetermined number (seven in this embodiment) of the proximity switch input circuits 101c is obtained. ing. Further, since the sub-board 105 is provided with a passage line 105b that matches the number of proximity switches and a conversion circuit 105a that matches the number of mechanical switches, the specifications are similar to those of the pachinko machine 1 and the pachinko machine 1 ′. Even if the number of proximity switches is changed by the above, it is only necessary to change the sub board 105 to the sub board 105 ′, and even if the specifications of the pachinko machine 1 and the pachinko machine 1 ′ are changed, the main control board 101 is shared. Can be used.

And since the number of mechanical switches is set so as to satisfy the above-mentioned formulas (1) to (3), the number of normal winning holes provided in the game board 4 is within the range of the number of normal winning holes. The number of mechanical switches allocated to detect winning game balls can be adjusted, and the number of conversion circuits 105a on the sub-board 105 can be changed to match the number of mechanical switches. Thus, since the number of proximity switch input circuits 101c and the total number of proximity switches and mechanical switches can be made the same, even if the number of proximity switches changes according to the specifications of the pachinko machine, the main control The common main control board 101 can be used without making an empty terminal on the board 101.
