Abstract

PURPOSE: To prevent a drive ball from colliding with a game board, or allow it to collide with the game board with small force, and stably stop the drive ball in a short time by forming an inclined face on a ball receiving recess, and applying the force of the component parallel with the game board. CONSTITUTION: When a driving hammer is tilted and the drive preparation is completed, an interlocking lever 20 is rocked to thrust up the coupling pin 21 of a feed control member 7. The ball stop section 18 of the feed control member 7 is retreated from a case trough 5, and the front drive ball is mounted on a ball receiving recess 22. When the driving hammer is returned from the drive preparation position, the interlocking lever 20 is returned to the original position to release the thrust-up of the feed control member 7. The feed control member 7 is returned to the initial position by the weight of the drive ball on the ball receiving recess 22 and the excitation by a heavy bob section 19, and the drive ball is discharged onto a driving rail (s) from a ball outlet 14. The force of the component parallel with a game board (u) is applied to the drive ball by the inclination of the ball receiving recess 22, and the drive ball does not collide with the game board (u).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a launching ball supply device for sending launching balls (pachinko balls) of a ball tray to a launching portion of a launching rail one by one in conjunction with the movement of a hammer or the like.

[0002]

2. Description of the Related Art As a conventional launch ball supply device,
There is No. 38859. As shown in FIGS. 5 and 6, this launch ball supply device has a ball entrance d communicating with the end of the ball dish c via a front plate r, and a ball exit e facing the launch part t of the launch rail s. Vertical case gutter f provided and the case gutter f
A horizontal axis g provided parallel to the game plate u surface at the lower end of
It is comprised of a supply control member h which is axially supported by the horizontal axis g and which reciprocally swings toward the firing rail s in the case gutter f.
The supply control member h has a ball stopper j formed on the top and a ball receiving recess k cut in an L-shape from the end of the ball stopper j, and is reciprocally rocked to move the case gutter f. The ball passage i is opened and closed by the ball stopper j, and the launch ball falling off the ball stopper j is received by the ball receiver k and discharged to the ball outlet e. In this supply control member h, an engagement pin m protruding parallel to the horizontal axis g is linked to a batting mallet via an interlocking lever n, and reciprocates once for each firing motion of the batting mallet.

[0003]

If the launch ball is not stationary at the launch portion t on the launch rail s before it is hit with a hammer, the ball flight is not stable. On the other hand, the launch ball supply device is set so as to send up to about 100 launch balls on the launch rail in one minute in conjunction with the hitting mallet, so that the launch balls are stopped within a very short time. Function is required.

Thus, in the conventional ball stopping portion j of the supply control member h, since the ball receiving concave portion k is parallel to the surface of the game board u, the launch ball is as shown by the arrow x in FIG. It is sent out with a straight force toward the u-face of the game board. Therefore, the launch ball first gets over the launch rail s and collides with the game board u,
It bounces back to the side of the launch ball supply device and sways for a while between the game board u and the launch ball supply device. Therefore, it takes too long until the launch ball comes to rest, resulting in unstable ball flight.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a launch ball supply device capable of stopping a launch ball in an extremely short time.

[0006]

In order to achieve the above object, the present invention is directed to a vertical case gutter which communicates with the end of the bowl on the front surface of a pachinko machine and through which one firing ball can pass, and a case gutter of the case. A ball stopper which is located at the lower end and which reciprocally swings about a horizontal axis parallel to the game plate, and a ball stopper formed above the horizontal axis, and a ball cut into a substantially L shape from the end of the ball stopper. In a launch ball supply device of a pachinko machine, which comprises a supply control member having a receiving concave portion, and one reciprocating swing of the supply control member sends out the launch balls of the case gutter one by one to the launch part of the game board. Provided is a launching ball supply device for a pachinko machine, in which an inclined surface for exerting a force of a component parallel to the game plate on the ball is formed in the ball receiving recess.

[0007]

By the inclined surface formed in the ball receiving concave portion of the supply control member, a force of a component parallel to the game board acts on the launching ball to be sent out. Therefore, the launch ball emitted from the supply control member does not collide with the game board, or collides with a force smaller than conventional. Therefore, the time to sway between the launch ball supply device and the game board after being placed on the launch rail is shortened, and the time to stand still is shortened, and as a result, the ball jump is stabilized.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of the launch ball supply device, FIG. 2 is an enlarged cross-sectional view of the main parts of the pachinko machine, FIG. 3 is an enlarged cross-sectional view of the main parts of the pachinko machine showing the operating state, and FIG. 4 is a front view of the pachinko machine. is there. As shown in FIG. 4, the pachinko machine P has a front plate 2 under a glass door frame 1, and a ball plate 3 attached to the front plate 2. The launch ball supply device 4 is arranged inside the front plate 2 in association with the end of the ball tray 3, and includes a device body 6 including a vertical case gutter 5 and a supply control member for sending out launch balls one by one. 7 and 7.

The apparatus main body 6 has a structure in which a mounting base 8 and a gutter base 9 screwed to the front surface of the mounting base 8 are coupled to each other, and a vertically elongated recessed portion 10 formed on the front surface of the mounting base 8.
A box-shaped case gutter 5 protruding from the front surface of the gutter base 9 forms a ball passage 11 through which one launch ball can pass. A ball inlet 13 is formed in the mounting base 8 so as to communicate with the end of the bowl 3 through the ball opening 12 of the front plate 2, and the bowl 3 and the case are formed through the ball opening 12 and the ball inlet 13. The gutter 5 communicates. On the other hand, in the case gutter 5 of the gutter base 9, a ball outlet 14 facing the firing rail s is formed on the lower front surface.
Further, the case gutter 5 has an open lower end, and a supply control member 7 is arranged at the lower end of the case gutter 5. A window hole 15 is formed in the front surface of the case gutter 5, and a ventilation hole 16 is formed in the upper portion of the mounting base 8 so as to communicate with the recess 10. This window hole 15 and ventilation hole 1
6 improves the air permeability in the case trough 5, so that the dirt such as tar and dust adhering to the case trough 5 becomes moist and sticks, which obstructs the flow of the launch ball. The harmful effect can be improved. Also, when a ball clogging occurs in the case gutter 5, the state of the launch ball can be confirmed through the window hole 15, and if a driver or the like is inserted into the window hole 15, the clogged launch ball can be moved. It is also effective in resolving problems.

The supply control member 7 is swingably supported by a horizontal shaft 17 installed at the lower end of the case gutter 5 in parallel with the game board u. The supply control member 7 has a ball stopper portion 18 above the horizontal shaft 17, and a weight portion 1 below the horizontal shaft 17.
There is 9. The top of the ball stopper 18 is located at a position substantially the same level as the upper end of the ball outlet 14 of the case gutter 5 and is formed in an arc shape around the horizontal axis 17. On the other hand, the weight portion 19 is formed in an arc shape around the horizontal axis 17,
The supply control member 7 is biased clockwise in FIG. In addition, an engagement pin 21 that engages with an interlocking lever 20 described later is provided on the side surface of the weight portion 19 so as to project. The supply control member 7 is provided with a ball receiving recessed portion 22 which is cut into a substantially L shape from the end of the ball stopper portion 18 downward. The ball receiving concave portion 22 has a size capable of holding one launch ball, and is gradually approached from the launch portion t of the launch rail s in the launch direction, that is, in the direction from the front to the other side in FIG. An inclined surface is formed that is slightly inclined in the direction.

Thus, the engagement pin 2 of the supply control member 7
1, one end of an interlocking lever 20 is engaged as shown by the chain double-dashed line in FIG. The interlocking lever 20 has an arm 24 extending below a swing shaft 23 engaged with a ball striking mallet 25 and swings in conjunction with the firing operation of the ball striking mallet 25, whereby an engagement pin of the supply control member 7 is provided. Push up 21.

Next, the operation of the launch ball supply device 4 will be described. Normally, when the batting mallet 25 is stationary, as shown in FIGS. 1 and 2, the end of the interlocking lever 20 is in a lowered position, and the ball stopper 18 of the supply control member 7 is located in the middle of the case gutter 5. It is in a closed state. Therefore, the firing ball flowing in from the ball dish 3 is stopped by the ball stopping portion 18 of the supply control member 7 and stopped.

In this state, when the hitting mallet 25 tilts to reach the firing preparation position, the interlocking lever 20 swings to push up the engaging pin 21 of the supply control member 7. As a result, as shown in FIG. 3, the ball stopper 18 of the supply control member 7 is retracted from the case gutter 5, and the leading ball is placed in the ball receiving recess 22. Then, when the batting mallet 25 vigorously returns from the firing preparation position, the interlocking lever 20 returns to the original position and the thrust of the supply control member 7 is released. Then, the weight of the launch ball in the ball receiving recess 22 and the bias of the weight portion 19 cause the supply control member 7 to move to the position shown in FIG.
As it returns to its initial position, the launch ball of the ball receiving recess 22 is discharged through the ball exit 14 onto the launch rail s. At this time, due to the inclination of the ball receiving concave portion 22 on the launch ball, the game board u
Since a force of a component parallel to is applied, the launch rail s slightly swings in the ball flying direction. As a result, the motion of the swaying ball swaying between the launching ball supply device 4 and the game board u is drastically reduced, and it stabilizes on the launching rail s within a short period of time, so it rolls straight and remains stationary at the launching portion t. On the other hand, the batting mallet 25 is pulled back to the firing preparation position again by the drive of a firing motor (not shown) and vigorously returns to hit the firing ball in the firing section t. Of course, when the hitting mallet 25 is tilted to the firing preparation position, the supply control member 7 swings in the same manner as described above and the ball receiving concave portion 22
The launch ball is placed on the ball and the hammer 25 launches the previous launch ball and at the same time sends the next launch ball onto the launch rail s.

Although the present invention has been described with reference to the embodiments, the present invention is of course not limited to the above embodiments. For example, the inclination direction of the ball receiving recess 22 may be the opposite direction to that shown. Also, the supply control member 7
Is not limited to the structure of being driven by the interlocking lever 20, and may be driven by the force of the solenoid or the like by operating a solenoid or a motor in synchronization with the ball hammer 25. Further, the hitting mallet 25 is illustrated as a typical means for launching a launch ball, and may have any structure as long as it has a function of launching the launch ball.

[0015]

According to the present invention, since the inclined surface is formed in the ball receiving concave portion of the supply control member and the force of the component parallel to the game plate is applied to the launching ball to be sent, the supply control member is discharged. The ball does not hit the game board, or
Collide with less force than before. Therefore, since there is less useless movement of the launch ball swaying between the launch ball supply device and the game board and the time to stand still is greatly shortened, there is an excellent effect of stabilizing the ball flight. .
