Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a firing device that is used in a pinball game machine such as a pachinko machine and has a function of adjusting the firing direction of a ball.

[Prior Art] For example, a firing device in a pachinko machine is equipped with a hammer-based firing mechanism as a ball firing means, but electric ball hitting devices that use a plunger type solenoid as a driving source are also known. It is also necessary to accurately set the direction in which the ball is launched.

[Problems to be Solved by the Invention] However, when actually assembling a pinball game machine, the direction in which the balls are launched may vary somewhat due to misalignment in the mounting position of the firing device. In particular, in a pachinko game machine in which the game board is arranged vertically, the ball fired from the firing device is moved along the guide rail on the game board surface, so the tip of the firing device is directed toward the entrance of the guide rail. In addition to determining the launch angle in the vertical direction, it is also important to ensure that the ball that comes out of the launcher does not collide with the launcher mounting plate or the front glass plate surface of the game machine before reaching the guide rail.
It is important to mount the firing device so that the direction of ball launch is parallel to the mounting surface. Therefore, when the launcher is attached to the mounting surface of the gaming machine,
Even if the mounting angle in the vertical direction parallel to the mounting surface changes slightly, it is sufficient for the ball to reach the guide rail. ) changes even slightly, the direction of the ball being launched will no longer be parallel to the mounting surface, and the ball may collide with the mounting surface or the glass surface.

However, although conventional technology has provided a firing device that allows adjustment of the vertical tilt angle when attached to a pinball game machine, there is no known device that allows adjustment of the mounting angle with respect to the mounting surface. do not have.

Therefore, the purpose of the present invention is to provide a ball launcher that can correct the launch direction of the hit ball by adjusting the mounting angle to the mounting surface of the pinball game machine even if the launch direction of the batted ball fluctuates when attached to the pinball game machine. The goal is to provide equipment.

[Means for Solving the Problems] The present invention provides a firing device equipped with a ball launching means for launching a ball toward the game board surface of a pinball game machine, in which the ball launching means is housed and a housing that is rotatably mounted in a direction perpendicular to the mounting surface using a predetermined position on the mounting surface of the machine as a fulcrum; an elastic member that presses the housing against the mounting surface; and a rotating side of the housing. and a manually operated adjustment member disposed between the mounting surface and the housing and having an inclined surface abutting against the mounting surface of the housing, the inclined surface of the adjustment member being manually operated to adjust the elastic member. The housing is characterized in that the mounting angle of the housing relative to the mounting surface is changed by moving the housing against the pressing force.

[Operation] When the firing device of the present invention is attached to the mounting surface of the pinball game machine, the inclined surface of the adjustment member located between the housing and the mounting surface comes into contact with the housing. Therefore, when the inclined surface of the adjustment member is manually moved, the housing in contact with the inclined surface rotates in a direction perpendicular to the mounting surface, and the mounting angle of the housing relative to the mounting surface changes. Thereby, the direction in which the ball is launched can be adjusted.

[Embodiments] Hereinafter, embodiments of the present invention shown in the accompanying drawings will be described.

FIGS. 1 and 2 show a firing device attached to the lower part of a pachinko machine as an embodiment of the present invention. This launching device 1 includes a ball launching section 3 consisting of a solenoid that reciprocates a plunger 2 using electromagnetic force, a ball guiding section 4 coupled to the protruding side of the plunger, and a ball launching section 3 that is mounted on a pachinko machine. Board 6
The connecting portion 5 is provided with a mechanism for adjusting the ball hitting direction. The structure and operation of the adjustment mechanism will be described later.

First, the solenoid of the ball launcher 3 is used to supply balls one by one to the ball guide 4 from a ball supply device 21 provided at the bottom of the back side of the front plate 20 of the pachinko machine as shown in FIG. It is excited by a drive signal sent from the control circuit of the pachinko machine in response to the
The plunger 2 is made to protrude. Then, the pachinko ball 7 held at the firing position of the ball guide part 4 is
The projecting force of the plunger 2 causes the ball to be sent out with force from the outlet 4a of the ball hitting guide section 4, as shown in FIG.

Next, the ball-hitting guide section 4 is made of a substantially cylindrical member that is integrally formed on the end surface of the plunger protruding side of a cylindrical housing 8 that surrounds the solenoid of the ball-launching section 3, and is made of a synthetic resin material and is integrally formed with the housing 8. Can be molded. Further, during assembly, the ball-hitting guide section 4 is coupled to the ball-launching section 3 by screwing the end surface of the housing 8 to the plunger protruding surface of the solenoid. A portion of the ball guide portion 4 from a position a predetermined distance away from the proximal end, that is, the joint surface with the housing 8, to the tip is cut out in the axial direction, and the cutout portion 4b is
It is provided to feed the ball from the ball feeding device 21 to the firing position, and its width is larger than the diameter of the ball 7, and its starting point is connected to the plunger 2 from the ball launcher 3 to determine the firing position of the ball 7. When it protrudes, its tip is closer to the solenoid. Further, the upper end portion located at the starting point of the notch portion 4b inside the ball-hitting guide portion 4 extends to a height through which the tip of the plunger 2 can pass, and the outside thereof forms a flat surface 4c.

Furthermore, on the inner lower surface of the cutout part of the ball guide part 4, there is a three-point support for the ball fed from the ball feeding device 21 to be brought into contact with the flat surface 4c and placed at the firing position, as shown in FIG. At the same time, a pair of protrusions 9 are arranged in parallel to support the ball launched by the tip of the plunger 2 at two points. The protrusion 9 can be easily made of a band plate made of metal or synthetic resin, for example, and can be easily attached by inserting it into a long groove formed in advance inside the ball-striking guide 4. When molding the part 4, it is also possible to integrally mold it as a strip-like protrusion, in which case manufacturing becomes simpler. Note that the protrusions provided on the inside of the ball guide section 4 are not limited to the pair of band plate-like protrusions as shown in the figure, but may be formed by inserting a band plate bent into a V shape, or by inserting a band plate bent into a V shape, or It can also be formed by integrally molding the lower surface into a V-shape.

Next, the connecting part 5 for fixing the ball launching part 3 to the mounting plate 6 of the pachinko machine is connected to both left and right ends of the upper overhang piece 10 that projects from the upper end of the housing 8 and to a lower part that projects from the center of the lower end of the housing 8. Overhang piece 1
It has three support shafts 12 that penetrate through 1, and each support shaft 12
A circular flange 13 forming the head of the and upper and lower overhang pieces 1
A coil spring 15 interposed between the recesses 14 formed at 0 and 11 allows the housing 8 to be
It is configured to be mounted by pressing it against the mounting plate 6 at a point. Then, the upper overhang piece 1 of the housing 8
An adjustment member 16 rotatably attached around each support shaft 12 is disposed between the mounting plate 6 and both left and right ends in which the recess 14 of 0 is formed.

Note that as a means for pressing the housing 8 against the mounting plate 6, an elastic member other than the coil spring 15 (for example, a plate-shaped spring or a rubber plate) may be used.

As shown in FIG. 3, each adjustment member 16 has an inclined surface 17 formed in an annular shape around a hole 18 through which the support shaft 12 passes, on a flat oval plate surface as a whole, and a slanted surface 17 formed in an annular manner around a hole 18 through which the support shaft 12 passes. When the firing device 1 is attached to the mounting plate 6 as shown in FIG.
comes into contact with the upper end of the back surface of the upper overhang piece 10 of the housing 8 . Therefore, when each adjustment member 16 is rotated appropriately, the distance between the upper overhang piece 10 pressed against the inclined surface 17 and the mounting plate 6 is changed by the pressing force of the spring 15, and thereby the lower overhang piece The mounting angle (clockwise angle in FIG. 2) of the firing device 1 relative to the mounting plate 6 changes using the support shaft portion of the piece 11 as a fulcrum. In this case, as shown in FIG. 1, when both the front and rear adjustment members 16 provided between the upper overhang piece 10 of the housing 8 and the mounting plate 6 are rotated to the same angular position, the upper overhang piece 10 is attached. Since it is parallel to the plate 6, the firing direction of the pachinko balls 7 is also parallel to the mounting plate 6.

On the other hand, if the ball guide part 4, which determines the launching direction of the pachinko ball 7, is not parallel to the mounting plate 6 when viewed from directly above, rotate one of the two adjustment members 16 to adjust the inclination. By increasing or decreasing the distance between the portion of the upper overhanging piece 10 that the surface 17 contacts and the mounting plate 6, the firing direction of the pachinko balls 7 can be adjusted to be parallel to the mounting plate 6.

The launcher 1 configured as described above is attached via the mounting plate 6 to the lower part of the base frame 22 installed on the front side of a pachinko machine as shown in FIG. 4, for example, and is located above the front. The pachinko balls 7 supplied one by one from the ball supply device 21 are launched from the launch position by the operation of the ball launch unit 3, and the ball guide unit 4
By forcefully jumping out from the front plate 23 toward the inclined plate 23, it can be sent between the two guide rails 24 and 25 on the game board surface of the front plate 20.

Although the illustrated embodiment has been described above, the present invention is not limited thereto. For example, although a plunger type solenoid is used as the ball ejecting means in the embodiment, the present invention is equally applicable to a ejecting device using a hammer ejecting mechanism. Further, the shape and mounting position of the adjusting member are not limited to those shown in the drawings, and the inclined surface may be formed so that the distance between the housing and the mounting surface can be changed by movement other than rotation.

[Effect of the invention] Since the firing device of the present invention is configured as described above, when it is attached to a pinball game machine, the mounting surface of the pinball game machine can be adjusted by operating the adjustment member as necessary. By changing the angle at which the firing device is attached to the ball, the firing direction of the ball can be adjusted correctly. Therefore, it is possible to prevent the fired ball from colliding with the mounting surface or the glass surface before reaching the guide rail on the game board surface.
