Description

Description: FIELD OF THE INVENTION The present invention relates to a ball launching device for a pachinko machine, and in particular, it does not use a conventional striking lever to hit a pachinko ball, but uses a rotating force to rotate the pachinko ball. The present invention relates to a ball launching device of a launching type.

(Prior Art) Although a pachinko ball is normally fired by a striking lever, the tip of the striking lever and the center of the pachinko ball must be correctly aligned in order to accurately fire the pachinko ball. In order to do so, a fairly sophisticated technique is required for the position adjustment, and there is a problem that it takes time to assemble the pachinko machine. In addition, the impact sound generated when hitting a pachinko ball has also been a problem. In order to solve this, a ball launching device using a rotating body has been proposed, and an example thereof is that shown in Japanese Utility Model Application Publication No. 102085 in 1984. In this ball launching device, a rotating body made of an elastic material is arranged and installed above a launching portion of a guide rail at a predetermined interval, and the rotating body is rotated by a drive motor.

According to this ball launching device, the pachinko ball is sandwiched between the guide rail base end and the rotating body, and is then launched along the guiding rail by the rotational force of the rotating body. Therefore, the rotating body frequently presses the pachinko ball to the base end of the guide rail, which causes the base end of the guide rail to be worn or damaged within a short period of time, which in turn causes accurate pachinko ball firing. It becomes difficult to replace the guide rail. Further, normally, it is desirable that the launching intensity of the pachinko ball can be changed according to the preference of the player, but if the configuration like this conventional ball launching device is used,
It is necessary to make it possible to change the driving force and the pressing strength of the pachinko ball by one rotating body, and in order to perform such a function, the driving mechanism of the rotating body may become very complicated. is there.

(Problems to be Solved by the Invention) Since the present invention has been made in view of the above problems,
The problem to be solved is that in a ball launching device for a pachinko machine that uses a rotating body, there is no wear or damage to the guide rail even after long-term use, and it is possible to accurately launch a pachinko ball, and the player Another object of the present invention is to provide a ball launching device having a simple structure, the launching intensity of which can be easily changed according to the preference of the player.

(Means for Solving the Problems) The means adopted by the present invention for solving the above problems is a pachinko machine for launching a pachinko ball supplied from a ball supply device toward a guide rail for guiding a game board surface. A ball launching device in a machine, comprising: a main rotating body that is rotationally driven by a drive motor; and a sub-rotating body that is rotatably arranged in the launching portion of the guide rail so as to face the main rotating body.
A ball launching device in a pachinko machine, characterized in that elastic bands are wound around and fixed to the outer circumferences of the main rotating body and the sub rotating body. That is, the ball launching device according to the present invention is one in which a pachinko ball is sandwiched between a pair of rotating bodies and is launched toward the guide rail by the rotational force of the rotating bodies.

(Operation) The operation of the ball launching device according to the present invention configured as described above will be described with reference to the reference numerals attached to the drawings. The main rotating body (20) is rotated by operating the handle (H). At the same time, pachinko balls (B) are supplied from above the introduction plate (13). This pachinko ball (B) enters between the main rotating body (20) and the sub rotating body (30) along the introduction plate (13), and is sandwiched by the main rotating body (20) and the sub rotating body (30). Fired by the rotational force of the main rotating body (20). Pachinko ball fired (B)
Is guided to the game board surface by the guide rail (11). At this time, the pachinko ball (B) is not hit by the striking lever as in the conventional case, but the main rotating body (20) having the rubber band (21) and the auxiliary rotating body (30) having the rubber band (31). Since it is sandwiched by) and sent out by the rotational force of the main rotating body (20), no noise is generated as in the case of hitting, and no impact is transmitted to the hand holding the handle (H). Further, in this ball launching device, the pachinko ball (B) is shot by being sandwiched between the main rotating body (20) and the sub rotating body (30), so that the pachinko ball is driven by one rotating body. The pachinko ball (B) is not strongly pressed against the guide rail (11) and the guide rail (11) is not worn or damaged as compared with the case of firing the ball.

(Examples) Next, the present invention will be described below according to the examples shown in the drawings. FIG. 1 shows a perspective view of an embodiment of a ball launching device according to the present invention.
It is configured by disposing a main rotating body (20) and a sub rotating body (30) in the vicinity of 1).

The guide rails (11), the main rotating body (20) and the auxiliary rotating body (30) are attached to a board (12), and the board (12) is fixed to the lower part of the game board surface of the pachinko machine. The guide rail (11)
It guides the fired ball to the upper part of the game board surface, and an opening (11a) is formed at a part of its base end. This opening (1
At the rear part of 1a), there is fixed an introduction plate (13) for introducing the spheres intermittently supplied from a sphere supply device (not shown) between the main rotary body (20) and the sub rotary body (30).

The main rotating body (20) is arranged above the opening (11a) with a distance about the diameter of the pachinko ball (B), and is driven by the drive motor (22) attached to the back surface of the substrate (12). Rotate in the direction of the arrow shown. Further, a rubber band (21) is wound around and fixed to the outer periphery of the main rotating body (20), so that the main rotating body (20) is assumed to have elasticity with respect to the pachinko ball (B). is there. In addition, serrations (2
1a) is applied.

The sub rotary body (30) is arranged below the main rotary body (20),
The upper end of this sub-rotor (30) is the opening (11a) of the guide rail (11).
It projects slightly upward from. This sub rotary body (30) is
In the case of this example, it rotates freely, and its position in the vertical direction can be slightly changed by a position adjusting device attached to the back surface of the substrate (12). The position adjustment device is operated by the handle (H) arranged on the front of the pachinko machine, and the auxiliary rotating body is operated according to the rotation amount of the handle (H).
Move (30) up and down. Further, a rubber band (31) is wound around and fixed to the outer periphery of the sub-rotating body (30), whereby the sub-rotating body (30) has elasticity with respect to the pachinko ball (B). . Also, serrations (31
a) has been applied.

Furthermore, in this example, by rotating the handle (H), the drive motor (22) of the main rotating body (20) is driven first, and the pachinko ball (B) supply device (not shown) supplies the pachinko ball. (B) is intermittently supplied from above the introduction plate (13). Further, by further rotating the handle (H), the position of the sub-rotating body (30) is adjusted upward or downward.

For the ball launching device configured as above, the handle
By operating (H), the main rotating body (20) rotates and the pachinko balls (B) are supplied from above the introduction plate (13). This pachinko ball (B) enters between the main rotating body (20) and the sub rotating body (30) along the introduction plate (13), and is sandwiched by the main rotating body (20) and the sub rotating body (30). Fired by the rotational force of the main rotating body (20). The launched pachinko ball (B) is guided to the game board surface by the guide rail (11). At this time, the pachinko ball (B) is the main rotating body having the rubber band (21).
Since it is sandwiched between the sub-rotating body (30) having the (20) and the rubber band (31) and is sent out by the rotational force of the main rotating body (20), noise such as when hitting is not generated, and the handle ( There is no impact on the hand holding H).

Further, in this ball launching device, since the pachinko ball (B) is shot by being sandwiched between the main rotating body (20) and the sub rotating body (30), the pachinko ball (B) is guided by the guide rail ( There is no strong pressure on 11) and there is no wear or damage to the guide rail (11).

In the above example, the sub-rotating body (30) which can be freely rotated, that is, the pachinko ball (B) is driven by the main rotating body (20) and rotated, is described below. With this configuration, it is possible to reach the target position on the game board for a long period of time without spinning the pachinko ball (B), and also after the game board reaches the pachinko ball (B). The falling direction of can be stabilized.

The falling direction of (B) can be stabilized.

Further, in the above example, the main rotating body (20) and the sub-rotating body
The case where the rubber band (21) and the rubber band (31) are fixed to the (30) has been explained, but since the hard pachinko balls (B) are sandwiched and repelled, sudden uneven wear is caused in a short time. It is expected that the rotating bodies (20) (30) will be replaced more frequently, but by configuring as described above, the replacement can be performed extremely easily, and the rotating bodies (20) (30) It is convenient because it can reduce the parts cost.

In the above example, if only the auxiliary rotating body (30) is configured to be able to move up and down, and this up and down movement is adjusted appropriately by operating the handle (H), the firing strength according to the player's preference can be set freely. It can be a ball launching device that can be selected. Of course, the main rotating body (20) and the sub-rotating body (30) rotate at their arranged positions, and even if the sub-rotating body (30) can be moved up and down, its moving range is small. Therefore, the space for storing the ball launching device does not need to be so large. Further, the ball launching device of the pachinko machine can be arranged not only at the launching part (base end) of the guide rail (11) but also above it, for example, by sandwiching the pachinko ball (B) and guiding it. The main rotating body (20) and the sub rotating body (30) may be arranged so as to face each other so that they can be fired toward the rail (11). As a result, the pachinko machine itself can be made compact, and a space for accommodating other devices can be secured if necessary.

(Effects of the Invention) As described in detail above, according to the ball launching device of the present invention, the guide rail is not worn or damaged even when used for a long period of time, and the pachinko ball is not spun. It is possible to reach the target position on the game board over a period of time and to stabilize the falling direction of the pachinko ball after reaching the game board, so that accurate pachinko ball firing can be realized. Since it is possible to easily replace a portion that is heavily worn, it is possible to provide a ball launching device that is easy to maintain and manage with a simple configuration.
