Description

  The present invention relates to a pachinko gaming machine, and more particularly to driving a decorative body unit that moves forward and backward in a direction substantially parallel to a game board surface.

In pachinko machines, various board parts such as a prize opening, windmill, variable display device, and lighting device are provided on the board surface of the game board in order to diversify the contents of the game, winning prizes during the game, and other situation changes The stage effect is enhanced by moving the movable panel surface parts in various directions. For example, when a game ball wins a start winning opening provided on the game board, the symbol displayed on the variable display device in the game board starts to change, and the symbol stopped after a predetermined time elapses is a predetermined jackpot symbol. When it becomes, it becomes a big hit state, and a player can acquire a lot of balls. In such a gaming machine, various display effects are performed in order to enhance the interest of the game.
In addition, as a prior document, for example, Patent Document 1 according to the proposal of the present applicant includes a first movable accessory that reciprocates in the left-right direction parallel to the board surface of the game board, and a reciprocation in the front-rear direction of the game board. And a second movable accessory. According to this, it is possible to realize an effect corresponding to the complexity and sophistication of game contents.

However, when each movable accessory is moved up and down and left and right using the gear mechanism, it is difficult to maintain the movable accessory in a state of being stopped at the retracted position. In other words, due to backlash between gears, dimensional error between members, etc., the movable accessory often stops in a state of being deviated from the original stop position to the game area side, obstructing the path of the game ball, This will cause the game to become less fun and less fun.
Such inconvenience is likely to occur in a board surface component having a structure in which a movable accessory is attached to the tip of a long arm that rotates in a direction parallel to the board surface around a rotation axis provided at one end. This is because when the long arm is stopped at the retracted position because the distance between the rotation shaft provided at one end of the long arm and the movable accessory provided at the other end is long, the long arm and the movable arm are movable. This is because it is difficult to reliably stop the retracted position due to the weight of the accessory and the backlash of the gear portion.
For example, a long arm made of a resin material or a metal member such as iron is fixed to the movable accessory side, and a permanent magnet is fixedly arranged on the game board side as a measure for reliably stopping the movable accessory at a normal retreat position. Therefore, it is conceivable to hold the metal member by a permanent magnet when the movable accessory reaches the stop position, but it is only for positioning with respect to the long arm made of resin material or the movable accessory. It is not a good idea because it is necessary to make a design change to attach a dedicated metal part, which increases the number of parts and the number of assembly steps.
In particular, when the target part to which the metal member is to be attached or the member located in front of the metal member is made of a transparent material, the metal member is visually observed from the front, so that the appearance deteriorates.
The present invention has been made in view of the above-described problems, and without adding a special part to the movable accessory side, the movable accessory that moves in a direction substantially parallel to the game board surface is set to the stop position. An object is to provide a pachinko machine that can be held.

The present invention has been made to solve the above-described problems, and can be realized by the following modes.
That is, the pachinko gaming machine according to the first aspect includes an arm member that moves forward and backward in a direction substantially parallel to the game board surface, a decorative body supported by the arm member, a motor, and a driving force from the motor. A link mechanism that transmits to the member and moves the arm member forward and backward, and a decorative unit provided with the link mechanism;

A voltage supply circuit to supply, a decorative board fixedly disposed so as to be positioned in front of at least a part of the decorative body when the decorative body is held in the stop position, and a back side of the decorative board, A space for accommodating at least a part of the decorative body, and when the decorative body is in the stop position, press against the front surface of at least a part of the decorative body by the back surface of the decorative board; A lower edge portion of the decorative board is fixed and erected on the game board surface so that the decorative body is elastically pressed rearward to be fixed at a predetermined position, and the voltage supply circuit includes a switch element. Connect multiple resistors in series or / and in parallel. A voltage reduction circuit configured by the above circuit, wherein the first drive voltage is supplied via the switch element, and the second drive voltage is supplied via the voltage reduction circuit. To do.
The pachinko gaming machine according to a second aspect is characterized in that the motor is a four-phase monopolar stepping motor.

  According to the present invention, the first driving voltage is supplied to the motor that drives the decorative body when the decorative body is advanced and retracted, and the second driving voltage lower than the first driving voltage is supplied to the motor when the decorative body is held at the stop position. As a result of having a voltage supply circuit that supplies the drive voltage, the metal member attached to the movable platen surface component is visually recognized from the front and deteriorates the appearance as in the case where the movable platen surface component is made of a transparent member.

FIG. 6 is a diagram illustrating a configuration of a voltage supply circuit that supplies a drive voltage to the motor 31.
The motor 31 shown in FIG. 6 is constituted by a four-phase unipolar stepping motor, for example. A drive voltage is supplied to the motor 31 from the voltage supply circuit 51. Further, four drive signals (A phase, B phase, A phase A, and phase B phase) are supplied from the lamp control board 141 shown in FIG.
The voltage supply circuit 51 includes a PNP transistor Q1, four resistors R1, R2, R3, R4, and a diode D1.
The PNP transistor Q1 is a switch element, the emitter is connected to a drive power supply that outputs a drive voltage Vcc (for example, 15V), and the collector is connected to the power supply terminal t1 of the motor 31. In addition, a drive / stop signal is input from the lamp control board 141 to the base.
A resistor R1 is connected between the base and emitter of the PNP transistor Q1, and a diode D1 is connected between the emitter and collector in the direction as shown.
Further, in the present embodiment, a voltage reducing circuit 52 is connected between the emitter and collector of the PNP transistor Q1. The voltage reducing circuit 52 is configured by connecting a resistor R4 in series to resistors R2 and R3 connected in parallel.

FIG. 7 is a diagram showing another configuration example of the voltage supply circuit. In addition, the same code | symbol is attached | subjected to the same part as FIG. 6, and description is abbreviate | omitted.
The voltage supply circuit shown in FIG. 7 is different from the power supply circuit shown in FIG. 6 in that the voltage reduction circuit 52 is configured by a single resistor R11.
In the voltage supply circuit 51 of the present embodiment configured as described above, when the movable panel surface component 20 is moved back and forth, the drive / stop signal from the lamp control board 141 becomes L (low) level. As a result, the PNP transistor Q1 is turned on, and the drive voltage Vcc of the drive power supply (not shown) is supplied to the power supply terminal t1 of the motor 31 via the PNP transistor Q1. That is, the first drive voltage substantially equal to the drive voltage Vcc of the drive power supply is applied to the power supply terminal t1 of the motor 31. As a result, the motor 31 drives the movable panel surface component 20 including the gimmick 22a to move forward and backward based on the four drive signals from the lamp control board 141.

On the other hand, when the movable surface component 20 of the movable surface component unit 25 is held at the stop position, the drive / stop signal from the lamp control board 141 becomes the H (high) level. As a result, the PNP transistor Q1 is turned off, and the drive voltage is supplied to the power supply terminal t1 of the motor 31 via the voltage reduction circuit 52. In this case, the drive voltage Vcc of the drive power supply is reduced by the resistance of the voltage reduction circuit 52, and the second drive voltage lower than the first drive voltage is applied to the power supply terminal t1 of the motor 31.
If it does in this way, the motor 31 will be in an excitation state by the 2nd drive voltage, and can hold | maintain the movable surface component 20 in a predetermined stop position. In the voltage supply circuit shown in FIG. 6, the level of the second drive voltage can be set as appropriate by changing the resistance values of the resistors R2 to R4 of the voltage reducing circuit 52. In the voltage supply circuit shown in FIG. 6, the voltage reduction circuit 52 is configured using the resistors R2 to R4, so that heat generated in the voltage reduction circuit 52 can be dispersed. In the voltage reduction circuit 52 shown in FIG. 6, the resistor R4 is connected in series to the resistors R2 and R3 connected in parallel. However, this is merely an example, and a plurality of the voltage reduction circuits 52 are provided. These resistors can be constituted by a series circuit, a parallel circuit, or a circuit arbitrarily combining them.
Further, the voltage supply circuit shown in FIG. 7 has an advantage that the voltage reducing circuit 52 can be easily configured because the voltage reducing circuit 52 is configured by one resistor R11.

As described above, in the pachinko gaming machine according to the present embodiment, when the movable platen surface component 20 of the movable platen surface component unit 25 is advanced or retracted, the first drive voltage is supplied to the motor 31 that drives the movable platen surface component 20 to move the movable platen surface component 20. When the component 20 is held at the stop position, the movable platen surface component 20 is formed of a transparent member by providing the motor 31 with a voltage supply circuit 50 that supplies a second drive voltage lower than the first drive voltage. As described above, when the movable platen surface component unit 25 is at the stop position, the movable platen surface component 25 is surely placed at the stop position while eliminating the problem that the metal member attached to the movable platen surface component 20 is visually recognized from the front and deteriorates the appearance. It can be held so that it does not protrude toward the game area.
In the present embodiment, the movable platen surface component 20 is held at the stop position by the second drive voltage lower than the first drive voltage. For example, the movable platen surface component 20 is held by the first drive voltage. Heat generation of the motor 31 can be suppressed as compared with the case of holding. If the heat generation of the motor 31 is suppressed in this way, the magnetic force of the motor 31 is reduced along with the heat generation, and the occurrence of a misstep of the motor 31 during the advance / retreat operation can be prevented.
