Description

  The present invention relates to a ball launcher unit of a pachinko machine for launching a ball supplied from a ball tray to a launch rail into a game area.

  A pachinko machine, which is a gaming machine, is provided with a ball launching device for launching a ball into the game area and a ball feeding device for sending the balls supplied from the ball tray to the ball launching device one by one. ing. The ball launcher has a launch rail and a ball cage for firing a ball stationary at a predetermined position on the launch rail.

  The ball feeding device has a structure as shown in FIG. 2 of Patent Document 1, for example, and has a ball feeding member and a ball feeding solenoid. In this ball feeder, a ball outlet to the launch rail is provided below the ball inlet from the ball tray. The ball feeding member has an upward ball receiving portion. A magnetic plate is attached to the ball feeding member, and is attracted when the solenoid is energized, and the ball feeding member rotates around the shaft to take the ball into the ball receiving portion. Next, when the solenoid is turned off and the ball feeding member returns to the state before suction and the position of the ball receiving portion coincides with the ball delivery port, the ball is delivered to the firing rail. The bullet ball fires a ball that is stationary on the firing rail. As described above, the ball feeding device sends the balls one by one to the firing rail in synchronization with the movement of the ball cage.

  Conventionally, as described above, since the solenoid is disposed sideways on the side of the ball feeding member that faces upward, it is not possible to secure a space for arranging the control board on the side of the ball feeding device. It was. Further, the control of the driving of the ball feeding member and the ball cage is performed by the control board. However, since many control components are individually mounted on the control board, the control board itself has a large area. For this reason, the ball feeder and the control board cannot be provided adjacent to each other, and the control board is disposed on the back side of the gaming machine. Therefore, since the control board is separate from the ball feeding device and the ball launching device, there is a problem that the number of parts increases, and the parts transportation cost and the pachinko machine assembly cost increase.

JP 2002-331080 A (FIG. 2)

  In view of the above-described conventional problems, an object of the present invention is to provide a ball launcher unit of a pachinko machine in which a ball feeder, a ball launcher, and a control board are integrated.

A ball launcher unit of a pachinko machine according to the present invention made to solve the above-mentioned problem is a ball launcher unit of a pachinko machine comprising a base plate and a lid united and applied to the base plate. Because
The base plate is provided with a ball launcher including a launch rail and a ball cage that launches a ball on the launch rail by driving a launch solenoid;
The lid includes a ball feeding device including a ball feeding member that sends the balls introduced from the ball tray to the firing rail one by one, and a control board on which a launch control module that controls the launch of the ball is mounted. They are provided adjacent to each other.

  In the above-described invention, the ball feeding device is assumed to be provided with a ball introducing path from the ball tray and a ball feeding path to the firing rail adjacent to the lid body. It is possible to arrange the control board on one side, secure a space for mounting the control board on the other side of the lid, and arrange the control board in this space.

  The launch control module includes a touch sensor unit that detects that the player has touched the operation handle, a volume unit that adjusts the ball launch intensity, and a switch input unit that detects an input signal that is switched by the player. , A signal selection unit for selecting a firing signal from the touch sensor unit and the volume unit and a stop signal from the switch input unit, and a ball feed solenoid and a firing solenoid are driven in synchronization by the firing signal from the signal selection unit And a solenoid control unit that transmits a firing control signal for this purpose.

  The base plate is integrally formed with at least a mounting base for screwing the firing rail, a lower guide member for dropping the return ball downward, and an upper guide member for stopping the ball on the firing rail. Can be formed.

  Since the ball launcher unit of the present invention is provided with the ball introduction path and the ball delivery path adjacent to the lid, the ball feed device is made smaller and a space for mounting the control board is secured next to the ball feed device. can do. Since the control board is equipped with a launch control module including a touch sensor part, a volume part, a switch input part, a signal selection part, and a solenoid control part, the control board itself can be reduced in area. . Therefore, since it becomes possible to attach the launch control board to the secured space, the ball feeder and the control board can be provided adjacent to the lid.

  As described above, since the ball feeding device, the ball launching device, and the control board are incorporated as one assembly, it is not necessary to transport these devices and the control board separately or to assemble them separately into the pachinko machine. . Therefore, an advantageous effect that the conveyance cost and the assembly cost can be greatly reduced can be obtained.

Hereinafter, embodiments of the present invention will be described.
1-4 is a diagram showing a ball launcher unit according to the present invention, wherein 1 is a substantially rectangular base plate made of synthetic resin, and 2 is a lid formed entirely in a box shape. The base plate 1 includes a ball launching device described later, and the lid 2 includes a ball feeding device and a control board adjacent to each other. The lid body 2 has locking pieces 21 on the left and right side surfaces, and the locking pieces 21 lock the side surfaces of the base plate 1 so as to be united with the base plate 1 and applied. The lid 2 can be combined with the base plate 1 so as to open and close the hinge around one end of the base plate 1 and then closed using a clip member or the like. The lid body 2 needs to be locked to the base plate 1 in a closed state, but an opening / closing mechanism and a closing mechanism for the lid body 2 can be appropriately structured.

  In FIG. 1, 22 is a ball introduction path from a ball tray (not shown), 23 is a storage chamber for a ball feeder, 24 is a storage chamber for the control board 7, and 25 is a ball launch port. Note that an input terminal 71 and an output terminal 72 described later of the control board 7 are not accommodated in the accommodation chamber 24 for connection to the outside. A firing solenoid H, which is a rotary solenoid, is disposed on the back side of the base plate 1 (FIG. 4).

  Since the firing solenoid H is 19 mm, which is the same thickness as the game board, with respect to the conventional thickness of several centimeters, the back surface of the firing solenoid H can be positioned in the same plane as the back surface of the game board. . This prevents the solenoid H from protruding to the back side of the game board, eliminates a gap with the board case provided on the back side, and prevents an illegal act from being applied to the gaming machine. In addition, since the launcher unit itself can be made thin, it has the effect that it can be stored in a limited depth space on the back side of the ball tray and the back side of the game board.

  The structure of the ball launcher is shown in FIG. The ball launcher 3 includes a base plate 1 made of synthetic resin and a launch rail 4 and a ball cage 5. The firing rail 4 is M-shaped in a side view formed by bending a metal plate, and a contact surface of a sphere is recessed in a V shape, and is screwed to a mounting base 41 formed integrally with the base plate 1. It is worn. Adjacent to the firing rail 4, a lower guide member 42 is provided for preventing a return ball caused by hitting from directly colliding with the firing rail 4. In the vicinity of the firing rail 4, an upper guide member 43 for stopping the ball at the bullet position is provided. The lower guide member 42 and the upper guide member 43 can be formed integrally with the base plate 1.

  The ball cage 5 includes a cage body 51 made of a thin metal plate, and a synthetic resin covering 52 formed to cover the rear end, one side, and the tip of the cage body 51 by insert molding. Since a bullet surface 53 is provided at the tip, and a hole 54 is formed in the vicinity of the bullet surface 53, the resilient force of the synthetic resin is increased so that the bullet surface 53 launches a ball with high impact. It is. The ball cage 5 has a step 59 for stopping rotation in the vicinity of the hole 54. The bullet sphere 53 only needs to collide with the sphere at the center of the bullet sphere 53, so the shape can be an appropriate shape such as a rectangle or a circle, and the width is less than the radius of the game sphere. However, it is preferable from the viewpoint of resource protection.

  The ball cage 5 is pivotally attached to the rotation shaft 55 of the firing solenoid H, and rotates between the upper stopper 56 and the lower stopper 57. The upper stopper 56 and the lower stopper 57 are each composed of base portions 561 and 571 formed integrally with the base plate 1 and synthetic resin cushion bodies 562 and 572 fitted therein.

  As shown in FIG. 14, the base 571 of the lower stopper 57 has a boss 573 that protrudes rearward. A hole 574 of the cushion body 572 is fitted into the boss 573 and is pressed by the firing solenoid H. The cushion body 572 is fixed. The upper stopper 56 has the same structure as the lower stopper 57. The firing rotation is started from the state in which the bullet ball cage 5 is in contact with the lower stopper 57, and the firing rotation is stopped by colliding with the upper stopper 56. Here, since the step 59 is collided with the lower end of the upper guide member 43 after the contact surface 58 of the ball cage 5 collides with the upper stopper 56, an excessive impact is applied to the cushion body 562. The durability of the cushion body 562 is improved.

  Furthermore, by providing the stopper 56 at the position farthest from the rotating shaft 55, the load on the ball cage 5 and the cushion body 562 due to the impact when the rotation is stopped can be reduced, and deformation and damage can be prevented. Can do. Furthermore, by taking a large distance, even if the position of the contact surface 58 of the stopper 56 is changed due to an error due to attachment or wear, the influence can be reduced.

A lid 2 is applied on the base plate 1 including the above-described ball launcher 3, and a ball feeder 6 and a control board 7 are disposed on the ball launcher 3 as shown in FIG. The
In the ball feeding device 6, the lid body 2 is provided with a ball introduction path 22 for receiving a ball from the ball tray and a ball feeding path 26 for feeding the ball to the firing rail 4 adjacent to each other. The front side (player side) of the ball introduction path 22 is opened, the rear side (base plate side) is closed, and the side surface on the delivery unit 26 side is opened. Since the bottom surface 221 of the sphere introduction path 22 is inclined downward toward the sphere delivery path 26, the sphere introduced from the sphere dish flows down toward the sphere delivery path 26. The ball delivery path 26 is closed on the front side and opened on the rear side, and the side surface on the side of the ball introduction path 22 communicates with the ball introduction path 22. By making the ball introduction path 22 and the ball delivery path 26 adjacent to each other, a connecting path that connects the ball introduction path 22 and the ball delivery path 26 becomes unnecessary, and the lateral width necessary for installation can be reduced.

  Improper acts such as making it easier to win using a ball with a diameter smaller than the normal dimension (φ11) (for example, φ10.5), or clogging a sensor with a ball with a larger diameter (for example, φ11.5) There is. Therefore, as a countermeasure, the width of the sphere introduction path 22 is set to 11.1 to 11.4 mm to prevent the entry of a sphere having a diameter of 11.5. Further, the width of the firing rail 4 and the upper guide member 43 is set to 10.6 to 10.9 mm so that a sphere of φ10.5 is dropped at the lower side without being held at the ball firing position.

  Reference numeral 8 denotes a ball feeding member, and a ball receiving recess 81 is mounted on a rotation shaft 82 in a lateral direction toward the ball introduction path 22. The ball receiving recess 81 is located in the ball delivery path 26. Since the ball feeding member 8 is formed on the ball stop piece 83 on the upper side of the ball receiving recess 81 and on the bottom surface 84 inclined lower from the front side to the rear side on the ball receiving recess 81, The taken-in sphere flows down toward the base plate 1 side. And since the iron plate 85 is being fixed to the upper surface of the ball feed member 8 and the ball feed solenoid T is arranged downward above it, the iron plate 85 is attracted by energization of the ball feed solenoid T, The ball feeding member 8 is rotated around a rotation shaft 82. The ball receiving recess 81 moves up and down in the ball delivery path 26. Since the ball feed solenoid T is directed downward, the lateral width of the space necessary for installation can be reduced. The state shown in FIG. 6 is a non-game state in which the ball feed solenoid T is not energized.

  As described above, the ball introduction path 22 and the ball delivery path 26 are provided adjacent to the lid 2, and the ball feed member 8 is placed sideways so that the ball receiving recess 81 is positioned in the ball delivery path 26. Since the ball feed solenoid T is disposed above the ball feed member 8, a space for mounting the control board 7 can be secured next to the ball feed device 6.

  The control board 7 is provided with an input terminal 71, an output terminal 72, and a ball launch control module 9 for controlling the launch of the ball. As shown in FIG. 12, the firing control module 9 includes a touch sensor unit 91, a volume unit 95, a switch input unit 92, a signal selection unit 93, and a solenoid control unit 94.

  The touch sensor unit 91 detects the player's tentacles from a touch sensor input unit attached to the operation handle, and transmits a firing signal to the signal selection unit 93. The volume unit 95 changes the resistance of the variable resistor in accordance with the rotation amount of the operation handle, and transmits the ball launch intensity corresponding to the resistance to the signal selection unit 93. The switch input unit 92 transmits a stop signal for stopping the ball firing to the signal selection unit 3 when a stop switch attached to the operation handle is operated by the player. The signal selection unit 93 selects either a firing signal from the touch sensor unit 91 or a stop signal from the switch input unit, and transmits the selected signal to the solenoid control unit 94.

  Based on the firing signal transmitted from the signal selection unit 93, the solenoid control unit 94 transmits a firing control signal to the ball feed solenoid T at a constant period, and synchronizes with the drive of the ball feed solenoid T to launch the firing solenoid H. Sends a launch control signal to

  In the ball launching device unit configured as described above, when the player operates the operation handle, the firing signal from the touch sensor unit 91 is selected by the signal selection unit 93, and the solenoid control unit 94 moves the ball feed solenoid T. And an output signal to the launch solenoid H. First, the ball feeder 6 is actuated by the output signal.

The introduction and delivery of spheres in the ball feeder 6 will be described below.
First, when the solenoid T is energized, the ball feeding member 8 that has been rotated downward is rotated upward. As a result, as shown in FIG. 7, the sphere passes through the sphere introduction path 22 and is guided to the sphere receiving recess 81 located in the sphere delivery path 26. 7 and 8, the ball is supported on the inner wall 261 of the ball delivery path 26. When the solenoid T is de-energized, the ball receiving recess 81 is lowered by its own weight (FIG. 9), so that the position of the ball receiving recess 81 matches the ball delivery port 262, and the ball is sent to the launch rail 4. (FIG. 10). When the ball receiving recess 81 descends, the upper ball stop piece 83 restricts the flow of the succeeding ball, so that the ball feeding member 8 can send the ball to the firing rail 4 one by one (FIG. 9).

  The solenoid control unit 94 issues an output signal to the firing solenoid H after a predetermined time has elapsed since the output signal was issued to the ball feed solenoid T. As a result, the tip of the bullet ball cage 5 is rotated upward to launch a ball on the firing rail 4. Upon completion of launching, the firing solenoid H is de-energized and the ball cage 5 is returned to its original position. The solenoid control unit 94 shifts to the next ball launch operation. In addition, even if the input conditions of the touch sensor unit 91 and the switch input unit 92 are turned on / off within one cycle of the output of the ball feed solenoid T, the ball feed cycle does not become short, and the ball feed cycle does not shorten. The ball is fired with the feed.
