BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine having an improved pachinko ball launch system and a lower structure of a game board.
[0002]
[Prior art]
Conventionally, as shown schematically in FIG. 5, a pachinko machine has a safe ball passage 2 and an out ball passage 3 provided on the back side of the game board 1, and a pachinko ball (safe ball) that has won a prize opening is provided. The game board 1 leads to a safe ball passage 2 on the back side of the game board 1 and is discharged through a winning ball detection device (not shown) for paying out a winning ball. The out ball collection port 4 at the bottom of the game board 1 is led to the out ball passage 3 on the back side of the game board 1 to be discharged.
[0003]
[Problems to be solved by the invention]
A conventional general pachinko machine launches a pachinko ball in a left direction along a launch rail 5 from a ball launcher (not shown) provided on the lower right side of the game board 1 on the front of the game board 1. Therefore, in order to smoothly guide the firing ball to the front surface of the game board 1, it is necessary to align the position of the firing rail 5 that crosses the lower part of the game board 1 left and right with the front surface of the game board 1. For this reason, in the plastic body frame 6 of the pachinko machine, the front surface of the plate-like portion 7 that is the mounting portion of the launch rail 5 is made to substantially coincide with the front face of the game board 1 so that the position of the launch rail 5 is changed to the game board. 1 It is arranged to the front.
[0004]
However, since the thickness dimension of the plate-like portion 7 of the main body frame 6 integrally formed of plastic is thinner than the thickness dimension of the game board 1, the back side of the plate-like part 7 is the back side of the game board 1 at the lower part of the game board 1. Therefore, the back surface of the plate-like portion 7 cannot be used as it is as a constituent surface of the out-ball passage 3. For this reason, a back plate 8 as another member is attached to the rear of the plate-like portion 7, and the constituent surface of the out ball passage 3 is formed by the back plate 8, so that the out ball passage 3 is lowered from the back surface of the game board 1. It is formed to extend straight.
However, this leads to an increase in the number of parts, leading to a cost increase and a reduction in assembly efficiency.
[0005]
The present invention has been made in view of such circumstances, and an object thereof is to provide a pachinko machine capable of simplifying the structure of the lower part of the game board.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a pachinko machine according to claim 1 of the present invention is a ball launcher for launching a pachinko ball upward toward a game board attached to a main body frame formed of plastic. attached to the side bottom, thereby forming the game board of at least a portion of the recessed to a position of the back surface by remote behind the game board with passage surface of the plate-like portion extending downwardly of said main body frame by the the passage face portion and the back cover, the passage of the pachinko ball which flows downward from the back side of the game board in which have configured.
[0007]
In this configuration, since the ball launching device is provided at one side lower part of the main body frame and the pachinko ball is fired upward therefrom, it is not necessary to dispose the firing rail so as to cross the right and left below the game board. For this reason, there is no need to align the front surface of the main body frame plate-shaped portion below the game board with the front surface of the game board, so there is no problem even if at least a part of the main body frame plate-shaped portion below the game board is recessed backward. . Therefore, the body frame plate portion below the game board, the passage surface formed by recessed to a position of the I back surface remote rear of the game board and the back cover, can Rukoto forming structure of the passage of the pachinko balls Thus, a pachinko ball passage extending downward from the back side of the game board can be formed without attaching a separate member as in the prior art.
[0008]
In this case, as described in claim 2, the storage space for the pachinko balls in the ball dish may be expanded rearward in accordance with the shape of the recess toward the rear of the main body frame plate-like portion. As described above, if the storage space of the ball tray is expanded rearward by using the recess shape of the main body frame plate-like portion to the rear, more pachinko balls can be stored. In addition, the pachinko balls can be stored relatively shallowly in the storage space expanded rearward rather than being stacked high upward, so that the weight of the pachinko balls has an influence on the downstream pachinko balls for the amount of storage. Less is required, back pressure is not so much, and ball flow is not hindered. In addition, since the ball tray is expanded rearward, the amount of protrusion of the ball tray to the front can be made comparable to that of the conventional ball tray, and the ball tray does not get in the way.
[0009]

For example, a safe ball that has won a prize in any of the start winning port 14, the variable winning device 16, the winning port 17, and the winning device 18 in the middle of falling is in the safe ball passage 36 (collective bowl) on the back side of the game board 12. In the process, one by one is detected and discharged by a safe ball detector (not shown). Each time one safe ball is detected, a predetermined number of prize balls are discharged from a prize ball discharge device (not shown), flow into the rear tray portion 40 and are stored in the ball tray 25. On the other hand, the out ball collected at the out ball collection port 19 without winning a prize is guided to the back side of the game board 12 and flows down through the out ball passage 37 and is discharged.
[0021]
In the embodiment described above, the ball launching device 20 is attached to the lower left part of the plastic main body frame 11 and the pachinko ball is fired upward from there. There is no need to arrange a traversing firing rail, and it is not necessary to align the front surface of the plate-like portion 27 with the front surface of the game board 12. For this reason, portions other than the ball launcher mounting portion 28 in the plate-like portion 27 can be recessed backward.
[0022]
Thereby, the plate-like portion 27 of the main body frame 11 can be recessed backward except for the ball launcher mounting portion 28 to form the passage surface portion 29. In the lower portion of the game board 12, the passage surface portion 29 A safe ball passage 36 and an out ball passage 37 can be configured by the back surface and the back cover 38. Therefore, it is not necessary to use a separate member as in the prior art, the structure of the lower part of the game board 12 can be simplified, the number of parts can be reduced, and accordingly, cost reduction and assembly efficiency can be improved. Can be realized.
[0023]
Further, since the storage space of the ball tray 25 is expanded rearward in accordance with the shape of the recess on the rear side of the passage surface portion 29 of the main body frame 11, more pachinko balls can be stored than before, and the front plate portion The amount of protrusion of 39 to the front can be made comparable to that of a conventional ball tray, and the ball tray 25 does not get in the way. In addition, the pachinko balls can be stored relatively shallowly in a wide storage space expanded rearward, rather than being piled upward in the ball dish 25, so that the weight of the pachinko balls is on the downstream side for the amount of storage. The back pressure exerted on the pachinko sphere can be reduced, and it can be prevented that the pachinko sphere forms a bridge to deteriorate the sphere flow.
[0024]
However, the ball tray 25 may be configured not to expand in accordance with the shape of the recess toward the rear of the passage surface portion 29, and even in this case, the intended purpose of the present invention can be achieved.
[0025]
In the present embodiment, the safe ball passage 36 and the out ball passage 37 are provided so as to be lined up on the left and right sides in order to suppress the rearward protrusion amount (see FIG. 1). However, it goes without saying that the safe ball passage 36 and the out ball passage 37 may be provided so as to be lined up in the front and rear as in the prior art . Essential is the back side of the passage surface 29, if the back surface by remote behind the gaming board 12, without using a separate member, safe ball passage 36 that extends from the back side of the game board 12 downwardly and out ball passage 37 Can be provided.
