Hereinafter, embodiments of the ball launching mechanism of the gaming machine of the present invention will be described with reference to the drawings.
Example 1
As shown in FIG. 1, the ball launching mechanism 4 of the gaming machine 1 of this example is disposed on the main body frame 2 of the gaming machine 1 and launches a gaming ball to the gaming area of the gaming board. The ball launching mechanism 4 is provided with a hitting ball 52 for launching a game ball on the rear surface side with respect to the base plate 51, and with a launch drive source 53 for applying driving force to the hitting ball 52 on the front side with respect to the base plate 51. Do it. The base plate 51 is in a state of being attached to the main body frame 2 from the front side, and in this attached state, between the front surface portion of the main body frame 2 and the base plate 51 (specifically, the front surface portion of the main body frame 2 and the hit ball) A predetermined space 22 is formed between the rear surface portion of the flange 52 and the rear surface portion. In addition, a ball discharge portion 23 that can discharge the game ball that has entered the space 22 to the outside of the main body frame 2 is formed below the predetermined space 22.

Hereinafter, the ball launching mechanism 4 of the gaming machine 1 of this example will be described in detail with reference to FIGS.
As shown in FIG. 2, the gaming machine 1 of this example is a pachinko gaming machine. A game board (not shown) for forming a game area is attached to the main body frame 2, and a ball tray panel 3 provided with a hitting ball supply tray and an auxiliary ball receiving tray is arranged on the front side of the main body frame 2 so as to be openable and closable. It is set up.
The main body frame 2 is formed with an overflow channel 26 that allows the game ball to flow down to the auxiliary ball tray when the hitting ball supply tray is filled with the game ball.

The ball launching mechanism 4 of this example is provided as one of the elements constituting the ball launching mechanism 4, and the ball launching device 5 having a function for launching a game ball is placed at a substantially central position (specifically, in the gaming machine 1). It is arranged at a position slightly on the right side of the center), and is configured to fire a game ball from this position toward the upper left.
On the main body frame 2, a launch rail 24 for guiding a game ball launched from the ball launcher 5 toward the game board is formed from the ball launcher 5 obliquely upward to the left. Further, a ball guide (outer rail) 25 for guiding the game ball toward the game area formed on the game board surface is formed in an arc shape at a position extended from the upper end of the launch rail 24. At the inner position of the ball guide 25, an inner rail (not shown) provided for partitioning the game area on the game board surface is arranged in a shape similar to the arc shape of the ball guide 25. Yes. The launched game ball is configured to be guided to the game area through the area between the ball guide 25 and the inner rail.

Then, between the firing rail 24 and the ball guide 25, a foul ball that is launched from the ball launching device 5 and then returns to the ball launching device 5 side without reaching the game area is collected. An inlet portion 271 for collecting to the flow path 27 is formed. The main foul ball collection flow path 27 is configured to return the foul ball to the hitting ball supply tray.
Most of the foul spheres are collected in the main foul sphere collecting flow path 27. On the other hand, when the fire balls (game balls) launched from the ball launcher 5 collide with the foul balls, the fire balls flow backward to the launch rail 24. There is a risk. Therefore, in the portion of the firing rail 24 closer to the ball launching device 5, the foul sphere collecting flow path 28 for collecting the foul sphere backflowed (returned) to the firing rail 24 and joining it to the overflow flow path 26. Is formed.

  As shown in FIG. 2, the firing rail 24 and the ball guide 25 of this example are gently formed with the inclination angle obliquely upward to the left, unlike the case of the substantially vertical firing method. In the case of the substantially vertical launch method, the game ball launched from the ball launcher 5 is not guided smoothly along the shape with respect to the ball guide 25, but directly played while bouncing multiple times. It was led to the area. Therefore, it becomes necessary to form a region between the ball guide 25 and the inner rail through which the launched game ball passes with a slight margin, and as a result, the arrangement position of the inner rail is positioned more outward. It became one of the factors that hindered the horizontal expansion of the game area of the game board.

  On the other hand, the game ball launched from the ball launching device 5 of this example hardly bounces against the ball guide 25 and is smoothly guided to the game area along the arc shape with respect to the ball guide 25. . As a result, the area between the ball guide 25 and the inner rail can be made narrower. As a result, the arrangement position of the inner rail can be more outwardly positioned, and the left and right direction of the game area of the game board Can be expanded more. Moreover, the loss applied to the game ball launched from the ball launcher 5 can be reduced, and the capacity of the launch drive source 53 can be reduced.

  FIG. 3 shows the periphery of the ball discharge portion 23 formed in the main body frame 2. The ball discharge portion 23 includes a ball discharge passage 232 formed at the lower end portion of the attachment portion 21 of the main body frame 2 for attaching the base plate 51 so as to incline downward toward the left and right sides, and a ball discharge passage 232. And a ball discharge port 231 through which the game ball is discharged forward from the base plate 5. A base plate 51 is attached to the attachment portion 21 in a state where the hitting ball 52 is rotatable. In addition, a predetermined space 22 is formed in the mounting portion 21 so that a game ball that has entered unintentionally is discharged from the periphery of the hitting ball 52 without being placed on the hitting ball 52 or the like as it is. .

FIG. 4 shows a state where the ball launching device 5 of this example is viewed from the front side of the base plate 51, and FIG. 5 shows a state where the ball launching device 5 of this example is viewed from the rear side of the base plate 51.
The hitting ball 52 rotates around a rotation center portion 522 to which a motor as the firing drive source 53 is attached, and hits a game ball placed on the launch pad 56 of the launch rail 24 by the hitting ball tip portion 521. It is configured to fire. The hitting ball 52 is provided in a specific direction from the rotation center portion 522, and is provided with a long arm portion 523 provided with a hitting ball tip 521, and provided in another specific direction from the rotation center portion 522, and a launch rubber stopper described later. It is formed in a substantially “<” shape by a short arm portion 524 that abuts on 55. In FIG. 4 and FIG. 5, the game ball arranged on the launch pad 56 is indicated by the symbol X.

The base plate 51 is provided with a standby rubber stopper 54 that comes into contact with the long arm portion 523 of the hitting ball 52 at the waiting position 501 from below to define the waiting position of the hitting ball 52. The standby rubber stopper 54 is housed and fixed in a standby rubber stopper housing member 541 provided on the front surface side of the base plate 51. The standby rubber stopper storage member 541 is disposed on the front surface side of the base plate 51 using mounting screws so as to be slightly rotatable (position adjustment). When the operator opens the ball tray panel 3 with respect to the main body frame 2, the arrangement position of the standby rubber stopper storage member 541 is finely adjusted to adjust the arrangement position of the standby rubber stopper 54 stored. Tweak the. Thereby, by slightly changing the standby position (initial position) of the hitting ball 52, fine adjustment of the firing strength of the game ball by the hitting ball 52 can be easily performed.
Further, the base plate 51 is in contact with the short arm portion 524 of the hitting ball 52 rotated to the hitting position 502 where the game ball is to be launched, and a launching rubber stopper for defining the turning position when firing the game ball. 55 is arranged.

  As shown in FIG. 1, the base plate 51 is attached to the attachment portion 21 of the main body frame 2 from the front side, and in this attachment state, the front surface portion of the attachment portion 21 of the main body frame 2 and the base plate 51 are concerned. (Specifically, between the front surface portion of the mounting portion 21 of the main body frame 2 and the rear surface portion of the hitting ball 52), a predetermined space 22 is formed. Further, a cylindrical storage portion 233 for storing a standby rubber stopper 54 that protrudes rearward from the rear surface of the base plate 51 is formed in the attachment portion 21 of the main body frame 2. In addition, a ball discharge portion 23 that can discharge the game ball that has entered the space 22 to the outside of the main body frame 2 is formed below the predetermined space 22.

In FIG. 6, a state in which the predetermined space 22 is formed between the front surface portion of the attachment portion 21 of the main body frame 2 and the base plate 51 is shown in a cross section viewed from the side.
As shown in FIG. 1, the base plate 51 is formed with an open notch 511 that opens the front side of the periphery of the hit ball tip 521 when the hit ball 52 is at the standby position 501. A person who performs maintenance can perform maintenance around the hitting ball tip 521 of the hitting ball 52 through the open notch 511.

The ball launching mechanism 4 of the gaming machine 1 of the present example is devised so as not to reduce the work efficiency when performing maintenance around the ball launching mechanism 4.
Specifically, in the ball launching device 5 of the present example, a hitting ball 52 is disposed on the rear surface side of the base plate 51, a firing drive source 53 is disposed on the front surface side of the base plate 51, and the base plate 51 is It is attached from the front side of the main body frame 2. Thereby, when installing the gaming machine 1 on the island facility, the launch drive source 53 of the ball launching device 5 provided at a substantially central position below the gaming machine 1 interferes with the ball tray provided at the lower portion of the island facility. You can avoid doing that.

Further, a predetermined space 22 is formed between the front surface portion of the main body frame 2 and the base plate 51 (specifically, between the front surface portion of the mounting portion 21 of the main body frame 2 and the rear surface portion of the hitting ball 52). In the lower part of the space 22, a ball discharge passage 232 and a ball discharge port 231 are formed as the ball discharge portion 23 so as to be connected to the cylindrical storage portion 233.
As a result, when the ball tray panel 3 is opened with respect to the main body frame 2 and maintenance around the ball launching mechanism 4 is performed, even if the game ball enters the space 22 unintentionally, the base plate 51 The game ball can be easily discharged to the outside of the main body frame 2 without removing it from the main body frame 2. Therefore, it is possible to prevent the maintenance work efficiency from deteriorating.

  Therefore, according to the ball launching mechanism 4 of the gaming machine 1 of this example, it is possible to easily avoid interference with the island facility where the gaming machine 1 is installed, and to prevent the maintenance work efficiency from deteriorating. it can.

The long arm portion 523 and the short arm portion 524 of the hitting ball 52 can be formed with an inclined surface that is inclined downward toward the rear. In this case, the game ball that has entered the long arm portion 523 or the short arm portion 524 can be appropriately flowed toward the predetermined space 22 formed behind the game ball without being placed there as it is. it can.
Further, the open cutout 511 of this example is formed in a substantially triangular fan-like cutout on the right side of the base plate 51. The shape of the open notch 511 is not limited to the above shape, and may be any shape as long as the periphery of the tip portion 521 of the hitting ball 52 is exposed to the front side. In addition, the base plate 51 may be configured such that the tip 521 of the hitting ball 52 protrudes outward from the base plate 51 without providing a notch shape.

Further, the base plate 51 is not only formed in a flat plate shape, but also can be formed in, for example, a substantially L-shaped section having an end bent backward or a substantially U-shaped section. A component formed by bending the base plate 51 can appropriately cover components such as the hitting ball 52 disposed behind the base plate 51.
In addition, the structure of the ball discharge unit 23 may be any structure as long as the game ball that has entered can be appropriately discharged.

(Example 2)
In this example, various variations are provided in which a cover member 6 that prevents a game ball from entering the space 22 formed in the attachment portion 21 of the main body frame 2 is detachably attached to the open notch 511 provided in the base plate 51. It is an example to show.
As shown in FIG. 7, the cover member 6 can be rotatably attached to the attachment portion 21 in the main body frame 2. The cover member 6 is rotated to an attachment position 601 that covers the opening notch 511 and covers the periphery of the hitting ball tip 521 in the hitting ball 52, and an opening position 602 that opens the opening notch 511 and opens the periphery of the hitting ball tip 521. Make it movable.

  Further, the cover member 6 can be attached to a rotation fulcrum 61 provided at the upper end of the attachment portion 21 by a screw or the like.
