Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, in pachinko machines, for example, Japanese Examined Patent Publication No. 2-35586 and Japanese Examined Patent Publication No. 4-62755.
As described in the publication, etc., the firing rail is attached to the synthetic resin middle plate (base frame) mounted on the front frame, and at the predetermined position corresponding to the firing rail on the front frame, A launch device is mounted for launching the supplied pachinko ball on the launch rail.

The middle plate is composed of an upper frame for holding and fixing the game board, and a lower plate integrally provided under the upper frame, and holds the game board on the upper frame. -In the fixed state, the front surface of the lower plate and the front surface of the game board are flush with each other.

The firing rail is attached to the front surface of the lower plate of the middle plate in an inclined manner.
In addition, the launching device includes a launching pestle that is rotatably supported with its upper end facing the lower end of the launching rail, and urges this launching rod in the direction in which its upper end faces the lower end of the launching rail. And a drive motor for rotating the launching punch against the biasing force of the coil spring and opening the launching punch at a predetermined turning position. When the firing handle is rotated, the drive motor operates, the firing pestle reciprocally rotates toward the firing rail, and the pachinko balls from the prize ball saucer sequentially supplied to the lower end of the firing rail are It is configured to be struck at the upper end of the launching pestle and fired along the launch rail.

[0005]

However, in general,
In a pachinko machine, the launching device is directly attached to the front frame, whereas the launch rail is attached to the front frame via the middle plate, so the relative position between the launch rail and the launching punch is displaced. As a result, there is a problem in that the center of the pachinko ball placed on the launch rail cannot be reliably pierced by the upper end of the launch pestle.

If the center of the pachinko ball is not reliably hit by the launching punch, irregular rotation of the pachinko ball occurs, causing so-called "flying unevenness" in which the direction and speed of the launching ball are not stable. In the above-mentioned conventional pachinko machine, it is necessary to adjust the relative position of the launch rail and the launching punch very delicately, and it takes a lot of time and effort to assemble or install the pachinko machine.

Even if the relative position between the launch rail and the launching pestle can be adjusted optimally, the positional relationship between the two will shift due to long-term use, so it is extremely difficult to prevent "unevenness" of the launch ball. It was difficult. The present invention has been made in view of such a problem, and an object thereof is to provide a pachinko machine capable of stably firing a pachinko ball.

[0008]

In order to achieve the above object, the present invention according to claim 1 is such that a plate rail mounted on a front frame is obliquely attached to a firing rail, and the front frame is provided. Attached to a predetermined position of the launch rail, the launch rod being pivotally supported with its upper end facing the lower end of the launch rail, and the launch rod attached to the launch rail in a direction in which its upper end faces the lower end of the launch rail. An urging member for urging, and a launching device having a drive means for rotating the firing pestle against the urging force of the urging member and then returning and rotating the urging member by the urging force of the urging member. In a pachinko machine, a rod-shaped member that is attached to the lower end of the launch rail and that projects a pachinko ball supplied on the launch rail at its tip end so as to reciprocally move in the longitudinal direction of the launch rail. , The rod-shaped member A second urging member for urging in a direction in which the rear end protrudes from the support member to the firing punch side,
The upper end of the launching pestle that rotates back strikes the rear end of the rod-shaped member, and the tip of the rod-shaped member protrudes from the support member to the upper end side of the firing rail, thereby The gist is a pachinko machine, which is configured to be launched from the launch rail.

According to a second aspect of the present invention, in the pachinko machine according to the first aspect, a plate portion having a larger area than the end surface of the rod-shaped member is provided at the rear end of the rod-shaped member. It is characterized by

[0010]

In the pachinko machine according to the first aspect of the present invention configured as described above, the firing rail is attached to the plate member mounted on the front frame in a tilted manner, and the predetermined position of the front frame. A launch device is attached to the.
The launching device urges the launching pestle, which is rotatably supported with its upper end facing the lower end of the launching rail, and the launching pestle in a direction in which its upper end is directed to the lower end of the launching rail. An urging member and a drive means for rotating the firing pestle against the urging force of the urging member and then returning and rotating the urging force by the urging force of the urging member.

A support member is attached to the lower end of the launch rail, and a rod-shaped member for ejecting the pachinko ball supplied onto the launch rail at its tip is attached to the support member. It is supported so that it can reciprocate in any direction. Further, the rod-shaped member is urged by the second urging member in the direction in which the rear end of the rod-shaped member projects from the support member toward the launching punch.

In such a pachinko machine according to the first aspect of the invention, the launching punch is rotated by the drive means against the biasing force of the biasing member and then returned by the biasing force of the biasing member. When moved, the rear end of the rod-shaped member supported by the supporting member on the launch rail side is hit by the upper end of the launching punch.

Then, the tip of the rod-shaped member projects from the support member toward the upper end of the launch rail, and the pachinko ball supplied onto the launch rail is projected by the tip of the rod-shaped member and is launched from the launch rail. . That is, in the pachinko machine according to claim 1, instead of directly hitting the pachinko ball on the launch rail with the upper end of the launching punch, a support member for reciprocally supporting the rod-shaped member is attached to the lower end portion of the launch rail. The pachinko ball is projected by hitting the rear end of the rod-shaped member with the upper end of the launching pestle that returns and pivots, and projecting the tip of the rod-shaped member from the support member toward the upper end of the firing rail.

Therefore, according to the pachinko machine according to the first aspect, even if the relative positions of the launch rail and the launching punch (launching device) are slightly displaced, the upper end of the launching punch even hits the rear end of the rod member. By doing so, the center of the pachinko ball can be reliably pushed by the tip of the rod-shaped member. Therefore, it is possible to stably launch the pachinko ball for a long period of time without the need for delicately adjusting the relative position between the launch rail and the launching pestle.

Next, in the pachinko machine according to claim 2,
In the pachinko machine according to claim 1, a plate portion having a larger area than the end surface of the rod-shaped member is provided at the rear end of the rod-shaped member. Therefore, according to the pachinko machine according to the second aspect, even when the relative position between the launch rail and the launch pestle is greatly displaced, the upper end of the launch pestle strikes the plate portion of the rod-shaped member. The tip of the rod-shaped member can be surely projected. Therefore, even when the relative position between the launch rail and the launching punch is significantly displaced, the pachinko ball can be stably launched.

In the present embodiment, the cylindrical member 32 and the frame member 34 (the lower frame 34a and the upper frame 34b) correspond to the supporting member. In the ball striking device 28 configured as described above, the launching punch 22 of the launching device 24 has the launching rail 18
When it is rotated to the lower end side, the upper end 22a of the launching punch 22 strikes the disc member 38, as shown by the arrow in FIG. 4 and FIG.

Then, the coil spring 36 contracts,
The coil spring 36 and the disk member 38 are the frame member 34.
The second tip end 30a of the rod-shaped member 30 protrudes from the side of the flange 32a of the cylindrical member 32 by that much. Then, the pachinko ball T supplied on the launch rail 18 and stopped by the ball stopping member 29.
Is the tip 30 of the rod-shaped member 30 protruding from the cylindrical member 32.
It will be pierced by a, and as a result, it will be fired from the firing rail 18 toward the guide rail 10 as shown by the arrow in FIG.

Since the diameter of the notch 29c provided in the wall portion 29b of the ball stopping member 29 is larger than the diameter of the flange 30b provided in the rod member 30,
The rod-shaped member 30 protruding from the cylindrical member 32 can hit the pachinko ball T without being hindered by the ball stopping member 29.

Next, the launching device 24 will be described with reference to FIGS. 3 and 6. 6 is a configuration diagram showing the launching device 24 together with the launching rail 18, the ball thrusting device 28, and the ball stopping member 29 from the back side (opposite side of FIG. 1) of the pachinko machine 2. Therefore, FIG. 3 shows the main part of the launching device 24 from the left side of FIG.

As shown in FIGS. 3 and 6, the launcher 24
Is a launching pestle 22 and a motor 58 as a driving means for tilting the launching pestle 22 on a mounting board 56 mounted on the back surface of the front plate portion 4a located below the lower plate M in the front frame 4. While rotating integrally with the support shaft 26a of the operation handle 26, a first pulley 62 to which one end of the wire 60 is attached, a second pulley 64 on which the wire 60 is bridged, and a first pulley of the wire 60 An end portion on the side opposite to the pulley 62 side includes a third pulley 68 attached via a tension adjusting plate 66.

Although not shown, the motor 58
Are attached by stays or the like fixed to the attachment substrate 56. Further, the motor 58 is operated by the operation handle 26.
Is configured to be energized when it is rotated.
Here, the launching punch 22 has its upper end 22a at the lower end of the launching rail 18, that is, the ball thrusting device 2 due to the bearing portion including the support shaft 70, the nut 72 and the like protruding from the mounting substrate 56.
8 is rotatably supported so as to face the disk member 38.

Then, at the launching punch 22, the upper end 22a thereof
A coil spring 74 as a biasing member that biases the launching punch 22 in a direction in which the upper end 22a moves toward the lower end of the launching rail 18 at a predetermined position between the rotation center position pivotally supported by the bearing portion. Is attached to the third pulley 68. The other end of the coil spring 74 is attached to the third pulley 68.

That is, when the operating handle 26 is rotated, in FIG. 6, the first pulley 62 rotates counterclockwise and the wire 60 is pulled to the left.
The third pulley 68 rotates clockwise and the coil spring 74 is pulled rightward.
As a result, the biasing force of the coil spring 74 with respect to the firing punch 22 is changed in accordance with the amount of rotation operation of the operation handle 26.

The tension adjusting plate 66 is formed so that its attachment angular position to the third pulley 68 can be adjusted, whereby the biasing force of the coil spring 74 can be finely adjusted. Further, in FIG. 6, S1 and S2
Is a rubber cushioning member fixed to the mounting substrate 56, and when the firing punch 22 is rotated by the urging force of the coil spring 74 (when rotated clockwise in FIG. 6), The cushion members S1 and S2 are brought into contact with each other to stop.

On the other hand, the launching punch 22 is provided with an arm 76 which rotates integrally with the launching punch 22.
A roller 78 extends horizontally from the tip of 6. A rotary member 80 is attached to the rotary shaft 58a of the motor 58, and a cam piece 80a engaging with and disengaging from the roller 78 extends from the rotary member 80.

Next, the launching device 2 constructed as described above.
4 will be described together with the operation of the ball striking device 28 with reference to FIGS. 6 and 7. 6 shows a state immediately after the pachinko ball T is fired, and FIG. 7 shows a state immediately before the pachinko ball T is fired.

First, when the operating handle 26 is rotated, the motor 58 is energized, and the cam piece 80a of the rotating member 80 rotates clockwise in FIG. 6 together with the rotating shaft 58a thereof. Then, the cam piece 80a becomes the arm 76.
When it is not engaged with the roller 78 provided on the
Since the firing rail 18 is returned to the lower end side and rotated, the upper end 22a thereof comes into contact with the disc member 38 of the ball thrusting device 28 and the tip end 30a of the rod member 30 projects, that is, the pachinko ball T is fired. It is in a state after finishing.

Thereafter, when the cam piece 80a further rotates and engages with the roller 78 provided on the arm 76, the launching punch 22 resists the biasing force of the coil spring 74, as shown in FIG. Tilted to the rear of 18. Then, the upper end 22a of the launching pestle 22 separates from the disc member 38 of the ball thrusting device 28. Therefore, in the ball thrusting device 28, the tip 30a of the rod-shaped member 30 is retracted by the urging force of the coil spring 36, and the rod-shaped member 30 is pulled. The rear end 30c side projects to the launching pestle 22 side. By this time, the ball supply device 20 supplies the pachinko ball T to be next fired to the side of the ball stopping member 29 opposite to the ball thrusting device 28 side (that is, the firing position).

Then, as shown in FIG. 6, the cam piece 80a
At the moment when is separated from the roller 78, the firing pestle 22 returns clockwise by the urging force of the coil spring 74 and rotates,
The disc member 38 of the ball striking device 28 is struck by the upper end 22a of the firing pestle 22 that rotates back.

Then, in the ball thrusting device 28, as described above, the tip 30a of the rod-shaped member 30 has the cylindrical member 32.
The pachinko ball T, which is projected from the flange 32a side of the sticking member 29 and rested on the launch rail 18 by the ball stopping member 29, is projected by the tip 30a of the rod-shaped member 30 and, as shown by the arrow in FIG. Is fired toward the guide rail 10.

After that, the cam piece 80a of the rotating member 80 is repeatedly engaged and disengaged with the roller 78, whereby the launching punch 22 is periodically tilted, whereby the pachinko ball T.
Are fired sequentially. As described above in detail, in the pachinko machine 2 of the present embodiment, instead of directly hitting the pachinko ball T on the launch rail 18 with the upper end 22a of the launching punch 22, the rod-shaped member 30 is provided at the lower end of the launch rail 18. Attaching a ball thrusting device 28 equipped with a
The disc member 38 attached to the rear end 30c of the rod-shaped member 30 is hit by the upper end 22a of 2 and the tip 30a of the rod-shaped member 30 is projected accordingly, so that the pachinko ball T is projected. .

Therefore, according to the pachinko machine 2 of this embodiment, even if the relative position between the launch rail 18 and the launching punch 22 (the launching device 24) is slightly shifted, the upper end 22a of the launching punch 22 is formed.
However, as long as it hits the disc member 38 attached to the rear end 30c of the rod-shaped member 30, the center of the pachinko ball T can be reliably projected by the tip 30a of the rod-shaped member 30.

Therefore, in spite of the construction in which the launching device 24 is directly attached to the front frame 4 and the launch rail 18 is attached to the front frame 4 via the lower plate M of the middle plate, the launch rail 18 and the launching punch are attached. It is possible to stably launch the pachinko ball T for a long period of time without the need for delicately adjusting the relative position with respect to 22 and for a long period of time.

Furthermore, in the pachinko machine 2 of this embodiment,
Since the disc member 38 having a larger area than the end surface of the rod-shaped member 30 is attached to the rear end 30c of the rod-shaped member 30, the relative position between the firing rail 18 and the firing punch 22 is further deviated. Even if the launch pestle 2
The upper end 22a of 2 strikes the disc member 38,
The tip 30a of 0 can be reliably projected.

Therefore, the pachinko ball T can be stably fired even when the relative positions of the firing rail 18 and the firing pestle 22 are further deviated from each other. Further, in the pachinko machine 2 of the present embodiment, the ball bearing 42 is embedded in the inner surface of the cylindrical member 32 that supports the rod-shaped member 30 so that the rod-shaped member 30 can reciprocate, so that the rod-shaped member 30 can be moved smoothly. Therefore, the kinetic energy when the launching punch 22 returns and rotates can be efficiently transmitted to the pachinko ball T.

In the ball thrusting device 28 of the above embodiment, the cylindrical member 32 and the frame member 34 (the lower frame 34a and the upper frame 34b).
Although and are formed separately, both members may be formed integrally. Further, in the above embodiment, the ball stopping member 2
9 is fixed on the launch rail 18 separately from the ball striking device 28, but a member for stopping the pachinko ball T may be provided integrally with the ball striking device 28. .

For example, in the ball thrusting device 28, a tubular member capable of inserting the flange 30b of the rod member 30 into the end of the flange 32a of the cylindrical member 32 or the frame member 34 is provided at the upper end side of the firing rail 18 (see FIG. 4). The pachinko ball T can be made to stand still by the tip of the tubular member.

On the other hand, a member for stopping the pachinko ball T may be fixed to the lower plate M of the middle plate, and the pachinko ball T may be held between the member and the launch rail 18 so as to be stationary. .
