Description

  The present invention relates to a gaming machine such as a pachinko gaming machine.

  Conventionally, as described in Patent Document 1 below, a pachinko gaming machine has a game ball launching means (a launch unit including a launch solenoid) that can launch a game ball toward a game area, and a launch that can be operated by a player. Operation means (a handle body including a touch sensor and the like) and a launch control board including a launch control circuit capable of controlling launch by the game ball launching means are provided. The launch control circuit of the launch control board can be operated when power of a predetermined voltage (for example, 5V) is supplied from the power supply board. Further, the game ball launching means can be driven by supplying power of a specific voltage (for example, 37V) different from a predetermined voltage from the power supply board.

  In this pachinko machine, when the player operates the firing operation means, an operation detection signal corresponding to the operation on the firing operation means is output from the firing operation means to the launch control circuit of the launch control board. The launch control circuit outputs a drive signal for driving the game ball launching means to the game ball launching means based on the input operation detection signal. As a result, the game ball launching means is driven, and the game ball is launched toward the game area.

JP 2011-10756 A

  By the way, the firing operation means requires power of a predetermined voltage (for example, 5 V) in order to output an operation detection signal in response to, for example, a player's operation. Therefore, there is a gaming machine in which the power supply board supplies power of a predetermined voltage to the launch control circuit of the launch control board and supplies power of the predetermined voltage to the launch operation means via the launch control board. That is, there is a gaming machine in which power of a predetermined voltage output from the power supply board is branched into two or more systems and supplied to the launch control circuit and launch operation means of the launch control board.

  However, in such a gaming machine, when a charged player touches the firing operation means, high-voltage noise due to static electricity passes through a power line through which a predetermined voltage of power flows from the firing operation means. Can be transmitted. If high-voltage noise is transmitted to the launch control board and a large current flows through the launch control circuit, the launch control circuit breaks down, causing malfunction of the game ball launching means.

  The present invention has been made in view of the above circumstances. That is, the problem is that in a gaming machine capable of supplying power of a predetermined voltage output from the power supply board to the launch control circuit and launch operation means of the launch control board, it is difficult to cause a failure of the launch control circuit. An object is to provide a possible gaming machine.

A general hold display 44 is included.

  The variable display of the first special symbol is performed in response to the winning of a game ball at the first start port 20. The variable display of the second special symbol is performed in response to a winning of a game ball at the second start port 21. In the following description, the first special symbol and the second special symbol may be collectively referred to as a special symbol. The first special symbol display 41a and the second special symbol display 41b may be collectively referred to as a special symbol display 41. Further, the first special figure hold indicator 43a and the second special figure hold indicator 43b may be collectively referred to as a special figure hold indicator 43.

  In the special symbol display 41, the special symbol is variably displayed (variable display) and then stopped to display a lottery (special symbol lottery, jackpot lottery) based on winning at the first starting port 20 or the second starting port 21. Inform the results. The special symbol that is stopped and displayed (the special symbol that is derived and displayed as the display result of the stop symbol and variable display) is one special symbol that is selected from a plurality of types of special symbols by the special symbol lottery. When the stop symbol is a predetermined special symbol (a special symbol of a specific stop mode, that is, a jackpot symbol), an open pattern corresponding to the type of the special symbol that has been stopped (that is, the winning type) Then, a special game (a jackpot game) is performed in which the first grand prize opening 30 or the second big prize opening 35 is opened.

  Specifically, the special symbol display 41 is composed of, for example, eight LEDs arranged side by side, and displays a special symbol corresponding to the result of the jackpot lottery (the jackpot lottery) according to the lighting mode. is there. When winning the jackpot, for example, “○ ●●● ○○ ●●” (○: lit, ●: unlit), the jackpot symbol (1, 2, 5 and 6) from the left is lit ( Special notification mode) is displayed.

  In the case of a loss, a lost symbol in which only the rightmost LED is lit, such as “●●●●●●● ○”, is displayed. You may employ | adopt the aspect which light-extinguishes all LED as a loss pattern. Note that the lost symbol is not a specific special symbol. In addition, before the special symbol is stopped and displayed, the special symbol variation display (variable display) is performed over a predetermined variation time. The variation display mode is, for example, such that light repeatedly flows from left to right. In this mode, the LED is turned on. The mode of the variable display may be anything such as all the LEDs blinking at once as long as each LED is not stopped (lighted display in a specific mode).

  In this pachinko gaming machine 1, when there is a winning game ball (win ball) at the first starting port 20 or the second starting port 21, various random number values such as jackpot random numbers acquired for the winning are special.

Yes.

  The special figure hold stored in the special figure hold storage unit 85 is digested when a special symbol based on the special figure hold can be variably displayed. Digesting a special figure hold means that a jackpot random number corresponding to the special figure hold is determined, and a special symbol variable display for indicating the determination result is executed. Therefore, in this pachinko gaming machine 1, when the variable display of the special symbol based on the winning of the game ball to the first starting port 20 or the second starting port 21 cannot be performed immediately after the winning, that is, the execution of the variable symbol variable display Even if there is a prize during the execution of a special game or during a special game, the right of lottery for the prize can be reserved up to a predetermined number.

  The number of special figure hold is displayed on the special figure hold display 43. Specifically, the special figure hold indicator 43 is composed of, for example, four LEDs, and displays the number of special figure holds by turning on the LEDs by the number of special figure holds.

  The variable display of the normal symbol is performed with the passage of the game ball to the gate 28 as an opportunity. The normal symbol display 42 notifies the result of the normal symbol lottery based on the passage of the game ball to the gate 28 by variably displaying the normal symbol and then displaying the stop symbol. A normal symbol that is stopped and displayed (a normal symbol that is derived and displayed as a variable display result) is one normal symbol selected from a plurality of types of normal symbols by a normal symbol lottery. When the stop-displayed normal symbol is a predetermined specific symbol (a normal symbol of a predetermined stop mode, that is, a normal winning symbol), the second start port 21 is opened with an opening pattern corresponding to the current gaming state. An auxiliary game to be performed is performed.

  Specifically, the normal symbol display 42 is composed of, for example, two LEDs (see FIG. 4), and displays a normal symbol corresponding to the result of the normal symbol lottery depending on the lighting state. For example, when the lottery result is a winning (ordinary winning), a normal winning symbol in which both LEDs are lit is displayed such as “◯◯” (◯: lit, ●: unlit). Further, when the lottery result is a loss, a normal lose symbol in which only the right LED is lit is displayed as “● ○”. You may employ | adopt the aspect which light-extinguishes all LED as a normal lose pattern. Note that the normal lose symbol is not a specific normal symbol. Before the normal symbol is stopped and displayed, the normal symbol is displayed for a predetermined variation time. The variation display mode is, for example, a mode in which both LEDs are alternately lit. The mode of the variable display may be anything such as all the LEDs blinking at once as long as each LED is not stopped (lighted display in a specific mode).

  In the pachinko gaming machine 1, when a game ball passes to the gate 28, the value of the normal symbol random number (hit random number) acquired for the passage is stored in the common figure storage unit 86 (see FIG. 6). Temporarily stored as figure hold. There is an upper limit to the number of universal map holds that can be stored in the general map hold storage unit 86, and the upper limit number of universal map holds in this embodiment is four.

  The general map reservation stored in the general map storage unit 86 is digested when the variable display of the normal symbol based on the general map storage becomes possible. The digestion of the general symbol hold means that a normal symbol random number (per random number) corresponding to the general symbol hold is determined and variable symbol display for displaying the determination result is executed. Therefore, in this pachinko gaming machine 1, when the variable display of the normal symbol based on the passage of the game ball to the gate 28 cannot be performed immediately after the passage, that is, during the execution of the variable symbol display of the normal symbol or the execution of the auxiliary game Even if there is a case, the right of the normal symbol lottery for the passage can be reserved up to a predetermined number.

  The number of the general map hold is displayed on the general map hold display 44. Specifically, the general-purpose hold indicator 44 is composed of, for example, four LEDs, and displays the number of general-purpose holds by turning on the LEDs by the number of general-purpose holds.

In addition, the paid-out ball rental is detected by the ball rental sensor 132 for counting.

  The launch control board 140 is a board provided with a launch control circuit (control IC) 141 (see FIG. 8) that can control the launch of the game ball by the launch unit 180 based on an operation of the handle main body 170 by the player. The launch control board 140 is connected to the launch unit 180 and is connected to the handle body 170 via the relay terminal board 150 and the launch relay terminal board 160.

  The handle main body (launching operation means) 170 can be rotated by the player, and includes a firing volume 171, a firing stop switch (single switch) 172, and a touch sensor (touch switch) 173. The firing volume 171 detects the amount of rotation of the handle body 170. A detection signal of the firing volume 171 (an operation detection signal based on the rotation amount of the handle body 170) is output from the firing volume 171 to the launch control board 140 via the launch relay terminal plate 160 and the relay terminal plate 150.

  The firing stop switch 172 is pressed when the player stops firing the game ball. The press on the firing stop switch 172 is detected by the launch control circuit 141 of the launch control board 140 as described later. The touch sensor 173 includes a touch electrode (not shown) that is attached to the handle body 170 so as to be exposed, and detects a human body (player) contact with the touch electrode. A detection signal of the touch sensor 173 (operation detection signal based on contact with the touch electrode) is output to the firing control board 140 via the launch relay terminal plate 160 and the relay terminal plate 150.

  The launch unit 180 launches a game ball toward the game area 3 based on a rotation operation of the handle main body 170 by the player, and includes a launch solenoid 181 and a ball feed solenoid 182. The firing solenoid 181 is driven by a drive signal (drive current) input from the launch control board 140 (launch control circuit 141), and moves a bullet cage (not shown). When the bullet ball cage moves, a game ball waiting at a predetermined position on a launch rail (not shown) is driven toward the game area 3. The ball feeding solenoid 182 is driven by a driving signal (driving current) input from the firing control board 140 (launching control circuit 141) to play game balls stored in the hitting ball supply tray 61 one by one on the firing rail. To send to the position.

  When the player rotates the handle body 170 in this manner, the firing volume 171 outputs a detection signal corresponding to the amount of rotation of the handle body 170, and the touch sensor 173 outputs a detection signal based on the touch electrode contact. These detection signals are input to the launch control circuit 141 (see FIG. 8) of the launch control board 140, and the launch control circuit 141 outputs drive signals to the ball feed solenoid 182 and the launch solenoid 181 based on these detection signals. Thereby, the ball feed solenoid 182 and the launch solenoid 181 are driven, and the game ball is launched toward the game area 3 with a strength corresponding to the rotation amount of the handle body 170. In this pachinko gaming machine 1, a single game ball is launched in about 0.6 seconds.

  Here, when the player presses the firing stop switch 172, the firing control circuit 141 of the launch control board 140 detects the press on the launch stop switch 172. As a result, the firing control circuit 141 does not drive the ball feed solenoid 182 and the firing solenoid 181. Therefore, even when the player rotates the handle main body 170, the firing of the game ball is stopped by pressing the firing stop switch 172.

In detail, the production control microcomputer 91 creates light emission pattern data (also referred to as data for determining lighting / extinction and light emission color, or lamp data) that determines the light emission mode of the frame lamp 66 and the panel lamp 5. Light emission of lamps such as the frame lamp 66 and the panel lamp 5 is controlled according to the data. Note that data stored in the ROM 93 of the sub-control board 90 is used to create the light emission pattern data.

  Further, the effect control microcomputer 91 operates the decorative movable body 15 (see FIG. 1) connected to the lamp control board 107 via the relay board 108 based on the command received from the main control board 80.

Then, the DC 37V power is supplied to the firing solenoid 181 from the 2 pin of the connector CN14 (see FIG. 8). The launch solenoid 181 is configured to supply DC 37V power to the launch control circuit 141 and then to the launch solenoid 181 from the launch control circuit 141 in order to control the strength of the drive by the launch control circuit 141. .

  As shown in FIG. 10B, the wiring Xb extends from the firing control circuit 141, and the tip of the wiring Xb is connected to the 1 pin of the connector CN14. Therefore, the drive signal output by the firing control circuit 141 is transmitted to the firing solenoid 181 through the wiring Xb and the pin 1 of the connector CN14 (see FIG. 8).

  As shown in FIG. 10A, the wiring RR extends from the three pins of the connector CN2, and the tip portion J1 of the wiring RR is branched into the wiring R1 and the wiring R2. The tip portion J1 of the wiring RR corresponds to the “branch portion” of the present invention, and will be referred to as “branch portion J1” below. By this branch portion J1, the power of DC5V flowing through the wiring RR is transmitted toward the wiring R1 and also toward the wiring R2.

  A first filter (first noise removing unit) F1 is connected to the wiring R1. The first filter F1 is composed of two coils (inductors) and one capacitor, and is a so-called three-element type low-pass filter. Two coils are connected in series to the wiring R1, and one capacitor is connected in parallel to the wiring R1. That is, one side of the capacitor is connected to the wiring R1, and the other side of the capacitor is connected to the ground G. The first filter F1 has, for example, a rated current of 6A, a rated voltage of 100V (DC), a withstand voltage of 250V (DC), and a capacitance of about 10,000 pF, and removes high-frequency noise by the wiring R1. is there. The first filter F1 can also be referred to as an EMI filter as a filter for eliminating electromagnetic interference.

  FIG. 16 shows the frequency characteristics of the insertion loss of the first filter F1 in this embodiment. That is, FIG. 16 shows how much the signal can be attenuated (removed) by the first filter F1, and it can be understood how much the gain (dB) of the signal is attenuated with respect to a certain frequency. As can be seen from FIG. 16, the insertion loss increases as the frequency increases to around 100 MHz, and the gain of the signal can be greatly attenuated. Thus, it can be seen that the first filter F1 is a low-pass filter capable of removing high-frequency components. The effect of the first filter F1 will be described later.

  A capacitor C2 is connected in parallel to the wiring R1. That is, one side of the capacitor C2 is connected to the wiring R1, and the other side of the capacitor C2 is connected to the ground G. Capacitor C2 serves as a low-pass filter that removes high-frequency components (high-frequency noise) contained in DC5V power. By this capacitor C2, it is possible to flow a high frequency component included in the power of DC5 toward the ground G. As a result, it is possible to suppress the DC5V voltage fluctuation and to stabilize the DC5V power.

  A Zener diode (control circuit protection means) ZD1 is connected in parallel to the wiring R1. That is, the anode side an of the Zener diode ZD1 is connected to the ground G, and the cathode side ks of the Zener diode ZD1 is connected to the wiring R1. When a voltage equal to or lower than a set Zener voltage (breakdown voltage) is applied, the Zener diode ZD1 hardly flows current toward the Zener diode ZD1. However, when a voltage larger than the Zener voltage is applied, the Zener diode ZD1 drops the applied voltage to be equal to the Zener voltage (constant voltage) by the Zener effect, and the current flows to the Zener diode ZD1. Make it easier to flow.

  In the Zener diode ZD1 of this embodiment, the Zener voltage is set to 6.1 V which is larger than 5V. Therefore, when a voltage of DC5V is applied to the wiring R1, the Zener effect does not occur, and current hardly flows from the wiring R1 through the Zener diode ZD1 to the ground G. On the other hand, when a voltage exceeding the Zener voltage 6.1V (excess voltage) is applied to the wiring R1, a Zener effect occurs, and current easily flows from the wiring R1 through the Zener diode ZD1 to the ground G1. The effect of the Zener diode ZD1 will be described later.

  As shown in FIG. 10B, the wiring R1 is branched into a wiring R1a, a wiring R1b, and a wiring R1c. In order to facilitate understanding that the voltage 5V applied to the wiring R1 in FIG. 10A and the voltages applied to the wirings R1a, R1b, and R1c in FIG. 10B are the same, “DC5V ( A) ". The wiring R1a and the wiring R1b are connected to the launch control circuit 141. Therefore, the DC5V power flowing through the wiring R1 is supplied to the launch control circuit 141 through the wirings R1a and R1b. In this way, the launch control circuit 141 can operate when supplied with DC 5V power.

  The wiring R1c is connected to the oscillation circuit 190. The oscillation circuit 190 oscillates the output signal so that the frequency of the output signal is about 100/60. A wiring R1d extends from the oscillation circuit 190, and the tip of the wiring R1d is connected to the firing control circuit 141. Therefore, the firing control circuit 141 controls driving of the firing solenoid 181 (output of the drive signal) and driving of the ball feed solenoid 182 based on the output signal input from the oscillation circuit 190. As a result, when the player rotates the handle main body 170, about 100 game balls can be launched per minute.

  On the other hand, as shown in FIG. 10A, a second filter (second noise removing means) F2 is connected to the wiring R2. The second filter F2 is composed of two coils and one capacitor. Two coils are connected in series with the wiring R2, and one capacitor is connected in parallel with the wiring R2. The second filter F2 is the same as the first filter F1 described above, and is a low-pass filter that can remove high-frequency components by the wiring R2. The effect of the second filter F2 will be described later.

  The wiring R2 is connected to the 3rd pin of the connector CN3 as shown in FIG. In order to make it easy to understand that the voltage 5V applied to the wiring R2 in FIG. 10A is the same as the voltage 5V applied to the wiring R2 in FIG. 10B, “DC5V (B)”. It is shown. Therefore, the DC5V power flowing through the wiring R2 does not go toward the firing control circuit 141, but goes toward the handle body 170 via the connector CN3 (see FIGS. 8 and 9).

  Further, the wiring U1 extends from the launch control circuit 141, and the tip of the wiring U1 is connected to the 6th pin of the connector C3. The 6th pin of the connector is connected to the wiring for transmitting the detection signal of the touch sensor 173 in the harness H2 (see FIG. 8). Therefore, the detection signal of the touch sensor 173 is input from the 6th pin of the connector CN3 to the launch control circuit 141 via the wiring U1.

  A surge absorber (surge absorbing means) SA1 is connected in parallel to the wiring U1. That is, one side of the surge absorber SA1 is connected to the wiring U1, and the other side of the surge absorber SA1 is connected to the ground G. The surge absorber SA1 is capable of absorbing the surge voltage when a surge voltage of several hundred V (300 V or more in this embodiment) is applied. That is, the surge absorber SA1 of the present embodiment has an absorbable surge voltage set to 300V or higher.

  Specifically, the surge absorber SA1 includes a thin film electrode disposed on the wiring U1 side and a thin film electrode disposed on the ground G side, and these electrodes are opposed to each other with a micro gap interposed therebetween. . Therefore, when a high voltage (surge voltage) due to electrostatic discharge is applied to the touch sensor 173 and a surge voltage of 300 V or more is applied to the surge absorber SA1, arc discharge occurs in the micro gap, and the two electrodes are electrically connected. It becomes a state. As a result, it is possible to absorb a surge voltage by causing a current due to the surge voltage to flow toward the ground G. Thus, the surge absorber SA1 can make it difficult for a high current due to the surge voltage to flow from the wiring U1 to the firing control circuit 141, and it is possible to make it difficult for the firing control circuit 141 to fail.

  Next, based on FIG. 11, the electric circuit of the conventional launch control board 140 by the present applicant will be described. In the following description, portions of the electrical circuit of the conventional launch control board 140 that are different from the electrical circuit of the launch control board 140 according to the present embodiment (see FIG. 10) will be mainly described. The description is omitted. As shown in FIG. 11A, one end of the wiring T1 is connected to the 3rd pin of the connector CN2. Then, as shown in FIG. 11B, the other end side of the wiring T1 is branched into a wiring T1a, a wiring T1b, a wiring T1c, and a wiring T1d.

  The wiring T1a and the wiring T1b are connected to the launch control circuit 141, and are substantially the same as the wiring R1a and the wiring R1b (see FIG. 10B) of the present embodiment described above. The wiring T1c is connected to the oscillation circuit 190 and is substantially the same as the wiring R1c of this embodiment described above (see FIG. 10B). The wiring T1d is connected to the 3rd pin of the connector CN3, and is substantially the same as the wiring R2 of this embodiment described above (see FIG. 10B).

  Next, a conventional electric circuit of the power supply board 200, the launch control board 140, the launch unit 180, and the handle body 170 will be schematically described with reference to FIG. In FIG. 12 and FIGS. 13 to 15 to be described later, the wiring through which the DC 5V power flows is indicated by a solid line. Further, the wiring through which the detection signal output from the handle main body 170 (detection signal of the touch sensor 173) is transmitted is indicated by a broken line. Further, the wiring through which the drive signal output from the launch control circuit 141 is transmitted is indicated by a one-dot chain line.

  As shown in FIG. 12, the first filter F1 is connected in series to the wiring T1 of the launch control board 140. The wirings T1a and T1b extend from the branch portion J2 of the wiring T1 toward the launch control circuit 141, and the wiring T1d extends from the branch portion J2 of the wiring T1 toward the handle main body 170. As is apparent from FIG. 12, in the conventional electric circuit, unlike the electric circuit of the present embodiment, no Zener diode is connected to the wirings T1a and T1b from the branch portion J2 to the launch control circuit 141. And the filter (filter corresponding to the 1st filter F1 and the 2nd filter F2) which can remove a high frequency component is not connected to wiring T1a and T1b and wiring T1d which goes to the direction of handle body 170 from branching part J2.

  Here, problems of the conventional electric circuit will be described with reference to FIG. As shown in FIG. 13, for example, when a player tries to rotate the handle body 170, a high voltage due to static electricity charged to the player is applied to the handle body 170 (particularly, the touch electrode of the touch sensor 173). Cases can arise. In this case, high-voltage noise based on static electricity can be transmitted to the launch control board 140 via the launch relay terminal plate 160 and the relay terminal plate 150 through the wiring (see the broken line in FIG. 12) for transmitting the detection signal. . When high-voltage noise is transmitted to the launch control board 140, the game ball may be rubbed with a decorative member made of synthetic resin, in addition to the case where static electricity is charged to the player as described above. May be caused by static electricity charged on the game ball.

  Thus, when high voltage noise is transmitted to the firing control board 140 and a high voltage of several hundred volts (300 V or more) is applied to the wiring U1, the micro gap of the surge absorber SA1 becomes conductive. As a result, it is possible to flow a high current due to high-voltage noise to the ground G instead of the firing control circuit 141. Therefore, in the wiring U1 that transmits the detection signal, it is possible to suppress a high current from flowing into the firing control circuit 141.

  However, when a high voltage due to static electricity is applied to the handle body 170, high-voltage noise may be transmitted to the launch control board 140 through a wiring through which DC 5V power flows. In this case, a high voltage may be instantaneously applied to the wirings T1d and T1a, T1b, so that a high current may flow into the firing control circuit 141. As a result, there is a possibility that the firing control circuit 141 may be broken or destroyed, and the firing unit 180 cannot be driven normally. FIG. 17 schematically shows a peak portion W1 of high-voltage noise flowing through the wirings T1a and T1b. The voltage of the peak portion W1 is about 10 V, and the time t1 is about 1 ns. FIG. 17 schematically shows the high-frequency component W2 included in the high-voltage noise flowing through the wirings T1a and T1b, and the time t2 is about 3 ns.

  Therefore, in the electric circuit of this embodiment, the above-described problems are dealt with as follows. In FIG. 14, the electric circuit of the power supply board 200, the launch control board 140, the launch unit 180, and the handle body 170 in this embodiment is schematically shown. As shown in FIG. 14, this embodiment is characterized in that a Zener diode ZD1 is connected to a wiring R1 from the branch portion J1 to the firing control circuit 141.

  Therefore, when high-voltage noise is transmitted to the firing control board 140 and a voltage of about 10 V (peak portion W1 shown in FIG. 16) is instantaneously applied to the wiring R1, as shown in FIG. 15, the wiring R1 Can flow to the ground G instead of the firing control circuit 141. That is, the Zener diode ZD1 lowers the peak portion W1 shown in FIG. 16 to the Zener voltage (6.1 V) to make it difficult for a high current to flow to the firing control circuit 141, while allowing a high current to easily flow to the ground G. It is possible. Therefore, when a high voltage due to static electricity is applied to the wirings R1 and R2, it is possible to make the firing control circuit 141 unlikely to fail or break. In the electric circuit of this embodiment, as in the conventional electric circuit, high-voltage noise is transmitted to the wiring U1 that transmits the detection signal, and a high voltage of several hundred volts (300 V or more) is applied to the wiring U1. Then, it is possible to suppress a high current from flowing into the firing control circuit 141 by the surge absorber SA1.

  In the electric circuit of the present embodiment, as shown in FIG. 14, the first filter F1 is arranged on the wiring R1 from the branch portion J1 to the launch control circuit 141. Therefore, when the DC5V power supplied from the power supply substrate 200 flows through the wiring R1, the first filter F1 causes the high frequency noise (high frequency component) included in the DC5V power to flow (attenuate) toward the ground G. It is possible to supply 5V DC power excluding high-frequency noise to the launch control circuit 141. Furthermore, even when high-voltage noise due to static electricity is transmitted from the handle body 170 to the launch control board 140, the first filter F1 can remove the high-frequency component W2 as shown in FIG. Therefore, it is possible to stabilize the DC5V power supplied to the launch control circuit 141, and to stabilize the operation of the launch control circuit 141.

  In the electric circuit of the present embodiment, as shown in FIG. 14, the second filter F2 is arranged on the wiring R2 from the branch portion J1 to the handle body 170. Therefore, when the DC5V power supplied from the power supply substrate 200 flows through the wiring R2, the second filter F2 allows the high-frequency noise included in the DC5V power to flow toward the ground G. It is possible to supply the power of the removed DC 5V to the handle body 170. Accordingly, it is possible to stabilize the DC5V power supplied to the handle body 170, and it is possible to stabilize the detection signal output operation by the firing volume 171 and the detection signal output operation by the touch sensor 173.

  The second filter F2 can remove the high-frequency component W2 as shown in FIG. 16 at the location of the wiring R2 when high voltage noise due to static electricity is transmitted from the handle body 170 to the launch control board 140. It is. Therefore, it is possible to suppress both adverse effects on the power supply substrate 200 due to static electricity and adverse effects on the launch control circuit 141 due to static electricity by the second filter F2 disposed on the wiring R2. The high-frequency noise traveling from the handle body 170 toward the firing control circuit 141 can be removed by the first filter F1 and the second filter F2, and the high-frequency noise based on static electricity can be removed from the firing control circuit 141. It is possible to make it harder to enter.

  In this embodiment, the wiring through which the DC 5V power flows in the harness H1 and the wiring RR correspond to the “common power line” of the present invention. The wiring R1 corresponds to the “first power line” of the present invention. Further, the wiring R2 and the wiring through which the DC5V power flows out of the harnesses H2, H3, H4, and H6 correspond to the “second power line” of the present invention. In addition, the wiring for transmitting the detection signal of the touch sensor 173 in the harnesses H2, H3, and H6 and the wiring U1 correspond to the “operation detection signal line” of the present invention.

4). Description of jackpot etc. In the pachinko gaming machine 1 of the present embodiment, there are “hits” and “off” as a result of the jackpot lottery (special symbol lottery). In the case of “hit”, the “hit symbol” is stopped and displayed on the special symbol display 41. In the case of “missing”, the “design symbol” is stopped and displayed on the special symbol display 41. When winning a jackpot, the winning prize opening (the first winning prize opening 30 and the second winning prize opening 35) is opened with an opening pattern corresponding to the type of special symbol (the type of jackpot) that is stopped and displayed. Is executed. The jackpot game is an example of a special game.

  In this embodiment, the jackpot game is a multi-round game (unit open game), an opening before the first round game is started (also referred to as OP), and an ending after the last round game is completed (Also expressed as ED). Each round game starts with the end of OP or the end of the previous round game, and ends with the start of the next round game or the start of ED. The closing time (interval time) of the big prize opening between round games is included in the open round game before the closing.

  There are several types of jackpots. The types of jackpots are as shown in FIGS. As shown in FIGS. 18 and 19, in this embodiment, there are two types of jackpots (V long jackpot and V short jackpot). The “V long jackpot” is a jackpot for operating the opening / closing member 32 and the opening / closing member 37 in a first opening pattern (V long opening pattern) that allows a game ball to pass through the specific area 39 during the jackpot game. The “V short jackpot” is a jackpot for operating the opening / closing member 32 and the opening / closing member 37 in a second opening pattern (V short opening pattern) in which a game ball cannot pass to the specific area 39 during the jackpot game.

  More specifically, as shown in FIG. 19, “V long jackpot” has a total number of rounds of 16R. From 1R to 13R and 15R, the first grand prize opening 30 is opened for a maximum of 25.0 seconds per 1R. 14R and 16R open the second grand prize opening 35 for a maximum of 25.0 seconds per 1R. In these 14R and 16R, passage to the specific area 39 in the second big prize opening 35 is easily possible.

  On the other hand, “V short jackpot” has a total number of rounds of 16R, but a substantial total number of rounds of 13R. In other words, from 1R to 13R, the first big prize opening 30 is opened for a maximum of 25.0 seconds per 1R, but at 15R, the first big prize opening 30 is opened only 0.08 seconds per 1R, and 14R and Even at 16R, the second grand prize opening 35 is opened only 0.08 seconds per 1R. Therefore, in this V short jackpot, from 14R to 16R, the opening time of the big winning opening is extremely short, and it is a round in which a prize ball cannot be expected. That is, the V short jackpot is a substantial jackpot of 13R.

  In addition, in 14R and 16R in the V short jackpot, the second grand prize opening 35 is opened, but the opening time is extremely short, and it is almost impossible for the game ball to pass through the specific area 39 in the second big prize opening 35. It is possible. At 14R and 16R in the V short jackpot, not only the opening time of the second big prize opening 35 is short, but also the opening timing of the second big prize opening 35 and the operation timing of the distribution member 71 (second state (FIG. 3 (see (B)) to the first state (see FIG. 3 (A)), it is almost impossible for the game ball to pass through the specific area 39.

  In the pachinko gaming machine 1 of the present embodiment, the gaming control microcomputer 81 changes the gaming state after the jackpot game to the high probability state described later based on the passing of the gaming ball to the specific area 39 in the jackpot game. Transition. Therefore, when the above-mentioned V long jackpot is won, the game state after the jackpot game can be shifted to the high probability state by passing the game ball to the specific area 39 during the execution of the jackpot game. On the other hand, when the V short jackpot is won, the game ball cannot be passed to the specific area 39 while the jackpot game is being executed. Therefore, the game state after the jackpot game is a normal probability state described later. (Non-high probability state).

  Here, in the present pachinko gaming machine 1, the lottery for determining whether or not the jackpot is won is performed based on the “big hit random number”, and the lottery for the type of winning jackpot is performed based on the “big hit type random number”. The jackpot random number takes a value in the range of 0 to 65535. The jackpot type random number takes a value in the range of 0-9. In addition to the jackpot random number and the jackpot type random number, the random numbers acquired based on the winning at the first starting port 20 or the second starting port 21 include “reach random number” and “special pattern variation pattern random number”. .

  The reach random number is a random number that determines whether or not a reach is generated in the effect design variation effect indicating the result when the result of the jackpot determination is out of place. Reach is a state where there is only one effect symbol that is variably displayed among a plurality of effect symbols (decorative symbols), and depending on which symbol the effect symbol that is variably displayed is stopped and displayed. It is a state (for example, a state of “7 ↓ 7”) that is a combination of effect symbols indicating a big win. It should be noted that the effect symbols that are stopped and displayed in the reach state may be displayed as if they are slightly shaken in the display screen 7a. This reach random number takes a value in the range of 0-127.

  The special figure fluctuation pattern random number is a random number for determining a fluctuation pattern including the fluctuation time of the special symbol. The special figure variation pattern random number takes a value in the range of 0-127. The random numbers acquired based on the passage through the gate 28 include a normal symbol random number (per random number) and a common symbol variation pattern random number. The normal symbol random number is a random number for a lottery (ordinary symbol lottery) for determining whether or not to perform an auxiliary game for opening the electric chew 22. The normal symbol random number takes a value in the range of 0 to 65535. The regular pattern variation pattern random number is a random number for determining a variation pattern including a variation time of a normal symbol. The usual fluctuation pattern random number takes a value in the range of 0-232.

5. Description of the gaming state Next, the gaming state of the pachinko gaming machine 1 of the present embodiment will be described. The special symbol display 41 and the normal symbol display 42 of the pachinko gaming machine 1 each have a probability variation function and a variation time shortening function. A state in which the probability variation function of the special symbol display 41 is activated is referred to as a “high probability state”, and a state in which it is not activated is referred to as a “normal probability state (non-high probability state)”. In the high probability state, the jackpot probability is higher than in the normal probability state. That is, the jackpot determination is performed using a jackpot determination table in which the value of the jackpot random number determined to be a jackpot is larger than the jackpot determination table used in the normal probability state (see FIG. 20A). That is, when the probability variation function of the special symbol display 41 is activated, the probability that the display result of the special symbol variable display by the special symbol display 41 (that is, the stop symbol) becomes a jackpot symbol compared to when the special symbol display 41 is not activated. Becomes higher.

  In addition, a state in which the function for reducing the variation time of the special symbol display 41 is in operation is referred to as “time-short state”, and a state in which the special symbol display 41 is not in operation is referred to as “non-time-short state”. In the short-time state, the variation time of the special symbol (the time from the start of variation display to the time when the display result is derived and displayed) is shorter than in the non-short-time state. As a result, in the short-time state, the pace of digestion of the special figure hold increases, and an effective winning (a prize that can be stored as the special figure hold) at the starting port is likely to occur. Therefore, it is possible to aim for a big hit with smooth progress of the game.

  The probability variation function and the variation time shortening function of the special symbol display 41 may be activated at the same time, or only one of them may be activated. The probability variation function and the variation time shortening function of the normal symbol display 42 operate in synchronization with the variation time shortening function of the special symbol display 41. That is, the probability variation function and the variation time shortening function of the normal symbol display 42 operate in the time-short state and do not operate in the non-time-short state. Therefore, in the short time state, the winning probability in the normal symbol lottery is higher than that in the non-short time state (see FIG. 20C). In the short time state, the normal symbol variation time is shorter than in the non-short time state. That is, when the fluctuation time shortening function of the normal symbol display 42 is activated, a shorter fluctuation time is easily selected as the fluctuation time of the variable symbol variable display compared to when the normal symbol display 42 is not activated.

  As shown in FIG. 21, in the time-saving state, the opening time of the electric chew 22 in the auxiliary game is longer than that in the non-time-saving state. That is, the open time extension function of the electric chew 22 is activated. However, in the time-saving state and the non-time-saving state, the number of times the electric chew 22 is opened in the auxiliary game is one. That is, in the time-short state, the function of increasing the number of times of opening the electric chew 22 is not activated. In the short time state, the function of increasing the number of times of opening the electric chew 22 may be activated.

  In the situation where the probability variation function and the variation time shortening function of the normal symbol display 42 and the open time extension function of the electronic chew 22 are activated, the electric chew 22 is compared with the case where these functions are not activated. Are frequently released, and game balls frequently win the second start port 21. As a result, the base, which is the ratio of the number of prize balls to the number of shot balls, becomes high. Therefore, a state in which these functions are activated is referred to as a “high base state”, and a state in which these functions are not activated is referred to as a “low base state”. In the high base state, it is possible to aim for a big hit without greatly reducing the hand-held game balls. The high base state is a state in which so-called electric support control (control to support winning at the second starting port 21 by the electric chew 22) is executed.

  In the high base state (electric support control state), the above-described plurality of functions may not operate. That is, the operation of one or more of the probability variation function of the normal symbol display 42, the variation time shortening function of the normal symbol display 42, the opening time extension function of the electric chew 22, and the opening frequency increasing function of the electric chew 22 Therefore, it is only necessary that the electric chew 22 be opened more easily than when the function is not activated. Further, the high base state (electric support control state) may be independently controlled without accompanying the time-short state.

  In the pachinko gaming machine 1 according to the present embodiment, the gaming state after the jackpot game by winning the V long jackpot is a high probability state, a short time state, and a high base if the game is passed to the specific area 39 during the jackpot game. State. This gaming state is particularly referred to as a “highly accurate base state”. The high-accuracy base state is terminated when a special symbol variable display is executed a predetermined number of times (100 times in the present embodiment) or when the jackpot is won and the jackpot game is executed.

  In addition, the game state after the jackpot game by winning the V short jackpot is a normal probability state (non-high probability state, i.e., if the specific area 39 is not passed during the jackpot game). A low probability state), a short time state, and a high base state. This gaming state is particularly referred to as a “low-accuracy base state”. The low-accuracy base state ends when a special symbol variable display is executed a predetermined number of times (100 times in this embodiment), or when the jackpot is won and the jackpot game is executed.

6). Operation of Pachinko Gaming Machine 1 Next, the operation of the game control microcomputer 81 will be described based on FIG. 22, and the operation of the effect control microcomputer 91 will be described based on FIG. First, the operation of the game control microcomputer 81 will be described.

  [Main-side timer interrupt processing] The game control microcomputer 81 repeats the main-side timer interrupt processing shown in FIG. 22 every short time, for example, 4 msec. First, the game control microcomputer 81 is a jackpot random number used in the jackpot lottery, a jackpot type random number for determining the type of jackpot, a reach random number for determining whether or not to reach a reach state in the decorative symbol variation effect, a special symbol variation pattern A random number update process is performed to update a special figure fluctuation pattern random number for determining the normal pattern random number (per random number) used for the normal symbol lottery, a normal figure fluctuation pattern random number for determining the fluctuation pattern of the normal symbol, and the like (S101).

  Next, the game control microcomputer 81 performs input processing (S102). In the input process (S102), various sensors (first start port sensor 20a, second start port sensor 21a, first big prize port sensor 30a, second big prize port sensor 35a, which are mainly attached to the pachinko gaming machine 1. The detection signals detected by the normal winning hole sensor 27a, the specific area sensor 39a, the non-specific area sensor 70a, etc. (see FIG. 6)) are read out, and payout data for paying out a winning ball corresponding to the type of the winning hole is stored in the RAM 84. Set to the output buffer.

  Subsequently, the game control microcomputer 81 executes a start port sensor detection process (S103), a special operation process (S104), and a normal operation process (S105). In the start port sensor detection process (S103), if the first start port sensor 20a or the second start port sensor 21a is ON, it is a big hit on the condition that there are less than four reserved memories corresponding to the ON start ports. Random numbers such as random numbers (big hit random numbers, big hit symbol random numbers, reach random numbers, and special figure variation pattern random numbers) are acquired. If the gate sensor 28a is ON, the normal symbol random number and the normal symbol variation pattern random number are acquired on condition that the number of hit random numbers already stored is less than four.

  In the special operation process (S104), a random number such as a jackpot random number acquired in the start port sensor process is determined, and a special symbol for displaying the determination result (variation display and stop display) is displayed. When displaying the special symbol, a special symbol variation start command (variation start command of the first special symbol or the second special symbol) including information on the variation pattern of the variation display of the special symbol is set in the output buffer of the RAM 84. If, as a result of the determination of the jackpot random number, if the jackpot is won, the first big prize opening 30 or the second big prize opening 35 is opened according to a predetermined opening pattern (opening time and number of opening times) shown in FIG. A jackpot game (special game) to be performed.

  In the normal operation process (S105), the normal symbol random number acquired in the start port sensor process is determined, and the normal symbol display (variation display and stop display) for notifying the determination result is performed. At the time of displaying the normal symbol, a common symbol variation start command including information on the variation pattern of the regular symbol variation display is set in the output buffer of the RAM 84. If, as a result of the determination of the normal symbol random number, a win is made per normal symbol, an auxiliary game is performed in which the electric chew 22 is opened according to a predetermined opening pattern (opening time and number of times of opening) shown in FIG.

  Next, the game control microcomputer 81 performs an output process (S106) for outputting the command set in each process described above to the sub-control board 90 and the like, and ends this process.

  In parallel with the above-described processing in the game control microcomputer 81, the effect control microcomputer 91 performs the process shown in FIG. The operation of the effect control microcomputer 91 will be described below.

  [Sub-side timer interrupt process] The effect control microcomputer 91 repeats the sub-side timer interrupt process as shown in FIG. 23 every predetermined short time. In the sub timer interruption process, first, a received command analysis process (S1001) described later is performed.

  In the received command analysis process (S1001), for example, if the effect control microcomputer 91 receives a special figure variation start command from the game control microcomputer 81, the variable effect pattern determination random number is acquired and the special figure change start command is obtained. One table is selected based on the analysis result. Next, the variation effect pattern is selected by determining the acquired random effect pattern determination random number using the selected table. Then, a change effect start command including information on the selected change effect pattern is set in the output buffer of the RAM 94.

  The effect control microcomputer 91 performs a command transmission process (S1002) following the received command analysis process (S1001). In the command transmission process (S1002), various commands set in the received command analysis process are transmitted to the image control board 100. When the command transmission process is executed, the image control board 100 that has received the various commands executes various effects (such as fluctuation effects and jackpot effects) using the image display device 7. For example, the image control board 100 that has received the change effect start command executes the change effect with the content specified in the change effect start command.

7). Effects of the Present Embodiment According to the pachinko gaming machine 1 of the present embodiment, as shown in FIG. 14, when the power of DC5V flows from the power supply board 200 to the wiring RR, the wiring R1, and the wiring R2 of the launch control board 140, the Zener diode ZD1 A voltage of DC5V is applied to At this time, since the voltage (DC5V) applied to the Zener diode ZD1 is lower than the Zener voltage (6.1V), the current flowing through the wiring R1 hardly flows toward the ground G through the Zener diode ZD1. Therefore, it is possible to supply DC5V power (current) to the launch control circuit 141, and to make the launch control circuit 141 operate normally.

  On the other hand, for example, when a charged player touches the handle main body 170, high voltage noise based on static electricity may be transmitted from the handle main body 170 to the wiring R2 and the wiring R1 of the launch control board 140. In this case, when a high voltage (a voltage of about 10 V exceeding 6.1 V) is applied to the Zener diode ZD1, a current due to high-voltage noise flows toward the ground G as shown in FIG. It is possible to make it difficult to flow toward the control circuit 141. Therefore, it is possible to make it difficult for the firing control circuit 141 to fail.

  Further, according to the present embodiment, since the Zener diode (control circuit protection means) ZD1 is simply connected to the wiring R1 in order to protect the launch control circuit 141, the control circuit protection means can be configured inexpensively and simply. It is. In addition, since the Zener diode ZD1 has been conventionally used as a control circuit protection means for a DC circuit, reliability can be increased. The present applicant has actually confirmed that the firing control circuit 141 does not fail or break by applying static electricity to the handle body 170 on a trial basis (discharging).

  Further, according to the present embodiment, the Zener diode ZD1 is connected to the wiring R1 extending from the branch portion J1 of the launch control board 140 toward the launch control circuit 141. Therefore, for example, compared with the case where the Zener diode ZD1 is connected to the wiring R2 extending from the branch portion J1 toward the handle body 170, it is possible to block high-voltage noise at a position closer to the firing control circuit 141. is there. Therefore, it is possible to more reliably cut off the high voltage noise for the launch control circuit 141.

  Further, according to this embodiment, a relatively high voltage (for example, 300 V or more) applied to the wiring (wiring shown by the broken line in FIG. 15) to which the detection signal of the touch sensor 173 is transmitted due to the discharge of the handle main body 170 due to static electricity. Can be handled by the surge absorber SA1. Further, a Zener diode ZD1 can cope with a relatively low voltage (for example, a voltage of about 10 V) applied to a wiring (wiring shown by a solid line in FIG. 15) through which DC5V power flows. In other words, in the wiring to which the detection signal of the touch sensor 173 is transmitted, the launch control circuit 141 is protected by the surge absorber SA1 as in the conventional case, and the Zener diode ZD1 is newly disposed in the wiring through which the power of DC5V flows. The firing control circuit 141 is protected from a certain amount of noise.

8). Modification Example A modification example will be described below. In the description of the modification, the same components as those of the first form of the pachinko gaming machine 1 are denoted by the same reference numerals as those of the first form, and the description thereof is omitted.

<Second form>
A gaming machine of the second form will be described based on FIG. In the first embodiment, as shown in FIG. 14, the Zener diode ZD1 is connected to the wiring R1 extending from the branch portion J1 toward the firing control circuit 141 in the firing control board 140. However, in the second embodiment, as shown in FIG. 24, the Zener diode ZD2 is connected to the wiring R2 extending from the branch portion J1 toward the handle body 170 in the firing control board 140. The Zener diode ZD2 has the same configuration as the Zener diode ZD1, and the Zener voltage is set to 6.1V. In the second embodiment, as in the first embodiment described above, when high voltage noise is transmitted from the handle body 170 to the launch control board 140 due to static electricity, a high voltage exceeding 5 V is instantaneously applied to the Zener diode ZD2. Is done. As a result, it is possible to cause a current due to high-voltage noise to flow toward the ground G, and to make it difficult for the firing control circuit 141 to fail.

<Third form>
Based on FIG. 25, the gaming machine of the third form will be described. In the first embodiment, as shown in FIG. 14, the Zener diode ZD1 is arranged on the launch control board 140. However, in the third embodiment, as shown in FIG. 24, a Zener diode ZD3 is arranged on the relay terminal plate 150. Zener diode ZD3 is connected in parallel to wiring 151 through which DC 5V power flows in relay terminal plate 150. The Zener diode ZD3 has the same configuration as the Zener diode ZD1, and the Zener voltage is set to 6.1V. Both ends of the wiring 151 are connected to a wiring through which DC5V power flows in the harnesses H2 and H3. In the third embodiment, as in the first embodiment described above, when high-voltage noise is transmitted from the handle body 170 to the relay terminal board 150 due to static electricity, a high voltage exceeding 5 V is instantaneously applied to the Zener diode ZD3. The As a result, it is possible to cause a current due to high-voltage noise to flow toward the ground G, and to make it difficult for the firing control circuit 141 to fail.

  As can be seen from the above description of the third embodiment, the position of the Zener diode is not limited to the firing control board 140, but is provided between the firing control circuit 141 and the handle body 170 and supplied from the power supply board 200. The wiring can be appropriately changed as long as it is a wiring through which DC5V power flows. Therefore, it may be arranged on the launch relay terminal plate 160 or the handle main body 170.

<4th form>
A gaming machine of the fourth form will be described based on FIG. In the first embodiment, as shown in FIG. 14, the control circuit protection means for protecting the firing control circuit 141 is constituted by the Zener diode ZD1. However, in the fourth embodiment, the control circuit protection means is composed of the varistor VR1. The varistor VR1 has a high electrical resistance when the applied voltage is low, but the electrical resistance rapidly decreases when the applied voltage exceeds a certain reference voltage (varistor voltage). The varistor VR1 of this embodiment is a chip-type multilayer varistor whose varistor voltage is set to, for example, several V (for example, 6V). One side of the varistor VR1 is connected to the wiring R1, and the other side of the varistor VR1 is connected to the ground G. ing.

  In this fourth embodiment, when electric power of DC5V flows from the power supply board 200 to the wiring RR, wiring R1, and wiring R2 of the launch control board 140, the electrical resistance of the varistor V1 is high. Therefore, it is possible to flow the current flowing through the wiring R1 toward the launch control circuit 141 while hardly flowing toward the ground G through the varistor VR1. On the other hand, when high-voltage noise is transmitted from the handle body 170 to the launch control board 140 due to static electricity, a high voltage (for example, about 10 V) exceeding the varistor voltage (6 V) is instantaneously applied to the varistor VR1. At this time, since the varistor VR1 sharply lowers the electric resistance, it is possible to make a current caused by high-voltage noise flow toward the ground G and hardly flow toward the firing control circuit 141. Therefore, it is possible to make it difficult for the firing control circuit 141 to fail even if the varistor VR1 is used instead of the Zener diode.

<5th form>
A fifth embodiment of the gaming machine will be described with reference to FIG. In the first embodiment, as shown in FIG. 14, the second filter F2 is arranged in the wiring R2. However, in the fifth embodiment, as shown in FIG. 26, the third filter F3 is arranged in the wiring RR instead of the second filter F2. The third filter F3 is a low-pass filter similar to the second filter F2 (first filter F1). Therefore, when the DC5V power supplied from the power supply substrate 200 flows through the wiring RR, the third filter F3 allows high-frequency noise (high-frequency component) included in the DC5V power to flow toward the ground G. The power of DC 5V supplied to the handle body 170 can be stabilized. Furthermore, when high-voltage noise due to static electricity is transmitted from the handle body 170 to the launch control board 140, the third filter F3 can remove the high-frequency component W2 as shown in FIG. An adverse effect on the substrate 200 can be suppressed.

<Other changes>
In each form mentioned above, the 1st filter F1, the 2nd filter F2, and the 3rd filter F3 were 3 element type low-pass filters comprised from two coils (inductors) and one capacitor. However, as a filter F4 shown in FIG. 28A, it may be a three-element type low-pass filter including one coil and two capacitors. Further, as a filter F5 shown in FIG. 28B, an LC2 element type low-pass filter including one coil and one capacitor may be used. Further, as a filter F6 shown in FIG. 28C, a CL2 element type low-pass filter including one capacitor and one coil may be used. Further, an L single low-pass filter including one coil may be used as a filter F7 shown in FIG. Further, as a filter F8 shown in FIG. 28E, a single-capacitor low-pass filter composed of one capacitor may be used. As the number of low-pass filter elements decreases, the slope of the line indicating the frequency characteristics of the insertion loss (see FIG. 16) becomes gentler, and it is difficult to remove (attenuate) high-frequency components. Therefore, it is preferable to use a three-element low-pass filter such as the first filter F1, the second filter F2, the third filter F3, and the filter F4 shown in FIG.

  In the above embodiments, the first filter F1, the second filter F2, and the third filter F3 are low-pass filters having the same configuration. However, the first filter F1, the second filter F2, and the third filter F3 may be low-pass filters having different configurations. For example, the first filter F1 uses a three-element low-pass filter according to a high-frequency component to be removed. For the second filter F2, a two-element type low-pass filter may be used. Further, the number of low-pass filters that remove high-frequency components in the wiring through which DC5V power flows is not limited to two, but may be one or three or more. Further, the first filter F1, the second filter F2, and the third filter F3 may be arranged at positions other than the positions shown in FIG. 14 and FIG. 27. For example, the second filter F2 or the third filter F3 is connected to the relay terminal plate. 150 may be arranged.

  In the first, second, third, and fifth embodiments, the Zener diodes ZD1, ZD2, and ZD3 whose Zener voltage is set to 6.1 V are used. However, the Zener voltage can be appropriately changed as long as it is higher than 5V. For example, a Zener diode whose Zener voltage is set to 8V may be used. However, considering that the surge absorber SA1 absorbs a surge voltage of 300V or more as described above and the Zener diode ZD1 corresponds to a voltage lower than the surge absorber SA1, the Zener voltage is less than 300V. Is preferably low. In particular, considering that the voltage applied to the wiring R1 is about 10V when high voltage noise due to static electricity is transmitted to the firing control board 140, the Zener voltage is more preferably lower than 10V. In the fourth embodiment, the varistor VR1 whose varistor voltage is set to 6V is used. However, a varistor whose varistor voltage is set to other than 6V may be used. In order to protect the firing control circuit 141, two or more Zener diodes or varistors may be arranged on the wiring R1 and the wiring R2, or a combination of a Zener diode and a varistor may be arranged.

  In each of the embodiments described above, the surge absorbing means capable of absorbing the surge voltage by the wiring U1 is the surge absorber SA1 using the micro gap. However, the surge absorbing means may be a surge absorber using a varistor, a gas arrester, or a Si voltage element (zener diode). The surge absorber SA1 can absorb a surge voltage of 300V or more, but it is of course possible to use a surge absorber whose absorbable surge voltage range is not 300V or more (for example, 200V or more).

  In each of the above embodiments, as shown in FIG. 6, the launch control board 140 and the dispensing control board 110 are separate control boards. However, the launch control board and the payout control board may be integrated, and the control board in which the launch control board and the payout control board are integrated also corresponds to the “launch control board” of the present invention.

  Further, in each of the above-described forms, the power supply board 200 has a power of DC 5 V (predetermined voltage) in order to operate the firing control circuit 141 and to cause the handle body 170 (the firing volume 171 and the touch sensor 173) to output a detection signal. However, you may supply the electric power of voltage values other than 5V. Further, in order to drive the firing unit 180 (the launch solenoid 181 and the ball feed solenoid 182), the power supply board 200 supplies power of DC 37V, but supplies power of a voltage value other than 37V (for example, 34V). Also good.

  Further, in each embodiment described above, as shown in FIG. 5, a main control board 80, a sub control board 90, an image control board 100, an audio control board 106, a payout control board 110, a launch control board 140, and a power supply board 200 are arranged. However, the arrangement of the control boards can be changed as appropriate. As shown in FIG. 6, the launch control board 140 and the handle body 170 are connected via the relay terminal board 150 and the launch relay terminal board 160, but the launch control board 140 and the handle body 170 are connected to each other. One or three or more relay boards may be interposed therebetween, and may be directly connected without using the relay board.

  Moreover, in each of the above-described forms, the pachinko gaming machine that is shifted to the high probability state based on the passing of the game ball to the specific area 39 has been described, but the pachinko gaming machine that is shifted to the high probability state according to the type of the special symbol, It may be configured as other types of gaming machines such as so-called type 1 type 2 mixing machine, type 2 type (feather type gaming machine), and the like.

  Moreover, in each above-mentioned form, as shown in FIG. 19, the big prize opening was opened, but the opening aspect of the big prize opening may not be restricted to these. In addition, the jackpot determination table shown in FIG. 20A, the reach determination table shown in FIG. 20B, and the normal symbol hit determination table shown in FIG. 20C are used. Of course it is possible. Of course, it is possible to combine the features of the above-described embodiments.
