Description

  The present invention relates to a ball game machine in which a game board is detachable and replaceable.

  As a pachinko machine, that is, a ball game machine, a game board provided with a circular game area as shown in Patent Document 1 is detachable and replaceable. In this system, the gaming board is detachably exchanged from the back side with respect to the gaming machine frame attached to the outer frame so as to be freely opened and closed. However, on the back side of the gaming machine frame, there is a mechanism board equipped with a storage tank, a ball alignment rail, a ball payout device, etc., and it is necessary to remove it when attaching and detaching the gaming board. It was. In particular, when working in the hall, it is necessary to pull out the ball in the storage tank, and it is difficult to work from the back side because the opening angle of the gaming machine frame is small, so the workability is very bad. There was a problem.

  In order to solve the above-described problems, Patent Document 2 provides a holding part on one side of a gaming machine frame so as to be rotatable, and a gaming board is mounted on the holding part by inserting from the front side. What has been made to be disclosed is disclosed. However, in this case, since the launch rail on the launcher side (primary rail) and the outer rail on the game board side (secondary rail) are mounted on separate boards, the center position of the rails after assembly is There is a problem that the ball easily collides with the outer rail, or the ball trajectory is unstable and unstable.

  Patent Document 3 discloses a structure in which a launch rail and an outer rail are integrally provided on a rail base. This eliminates the need for center alignment between the rails, and solves the problem that the ball hits the outer rail and the ball trajectory becomes unstable. However, since the rail base is detachably attached to the game board, it is difficult to remove the rail base from the old game board and attach it to the new game board when replacing the game board in bad conditions of pachinko halls. There was a problem that it was actually very difficult in terms of management.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view showing a state in which a bullet ball game machine of the present invention is opened, wherein 1 is a front frame having a glass window 11 and 3 is a game machine frame. Inside the gaming machine frame 3, a mounting base 4 is pivotally mounted so as to be horizontally rotatable, and a gaming board 5 is inserted and attached to the mounting base 4 from the side. Hereinafter, the front frame 1 side is assumed to be the front, the gaming machine frame 3 side is assumed to be the rear, and the left and right and the upper and lower sides will be described with reference to the state in which the ball game machine is viewed from the front.

  FIG. 2 is a view showing the gaming machine frame 3 to which the mounting base 4 is mounted. The gaming machine frame 3 is provided with a window portion 31 for mounting the gaming board 5. A fitting recess 33 is formed with a step 32. In addition, the lower surface 34 of the window portion 31 is formed with a plurality of protrusions 35 that are highly inclined from the front to the rear, and the game board 5 fitted in the window portion 31 is pushed upward to be firmly held without rattling. It has a structure to do.

  3 and 4 show details of the mounting base 4. The mounting base 4 is formed by bending a front surface 41 formed of a metal plate and upper and lower ends thereof in a U-shape toward the rear. And an insertion recess 42. At the entrance of the insertion recess 42, a guide plate 45 is provided that is formed by being bent obliquely outward from the entrance in order to facilitate the insertion of the game board 5. A curved portion 44 is formed at one end on the right side of the front surface 41 corresponding to a circular game area. Four screws for fixing the ball launcher 6 are provided below the mounting base 4. Further, the mounting base 4 has a left side plate 43, and a protrusion 46 for determining the vertical position of the game board 5 is formed on the side plate 43.

  The length in the left-right direction of the insertion recess 42 is set to a minimum necessary length compared to the length in the left-right direction of the game board 5 in order to cope with a detachment failure due to bending of the game board 5. Further, the length of the insertion recess 42 in the front-rear direction is about 1 mm thicker than the thickness of the game board 5 so that a slight play space is created in order to cope with the variation in the thickness of the game board 5. In addition, the left end portion of the front surface 41 is provided with hinge portions 47 on the upper side and the lower side, and these hinge portions 47 are mounted inside the gaming machine frame 3 so that the mounting base 4 can be rotated horizontally.

  As shown in FIG. 5, the front surface 41 of the mounting base 4 is provided with a launching device 6 and an outer rail 7 bent in an arc shape with a gradually decreasing curvature radius in the longitudinal direction. The launching device 6 has a casing 64 in which a foul ball collection port 63 is formed for collecting a ball that has been bulleted but does not reach a later-described game area 51 and has become a foul ball. Inside, a firing rail 61 and a plunger-type solenoid that spheres a ball on the firing rail 61, that is, a bullet baller 62, are disposed (FIG. 6). The outer rail 7 is made of stainless steel or super engineering plastic and has a circular cross section. Since the launching device 6 and the outer rail 7 to which the firing rail 61 is fixed are fixed at a required position on the front surface 41 that is on the same plane with the foul ball collection port 63 interposed therebetween, even when the game board 5 is replaced, the bullet The center position of the spherical orbit is not shifted. In addition, as the ballistic device 62, a rotary-type heel can be used instead of the direct-action heel.

  As shown in FIG. 7, the game board 5 has a square shape as a whole and is surrounded by the inner rail 8 to form a game area 51. The game board 5 has an upper side 52 and a bottom side 53, and an upper edge corner 54 and a lower edge corner 55 are formed at the respective left ends. The game board 5 can be attached to the attachment base 4 by inserting the upper edge corner 54 and the lower edge corner 55 through the insertion recess 42 from the right side while being guided by the guide plate 45 (FIGS. 9 and 10). At this time, the curved portion 44 is formed in the same shape as the inner rail 8, and a path for a launch ball is formed between the inner rail 8 and the outer rail 7. At the end of the inner rail 8, a return prevention valve 81 is provided to prevent the ball from returning from the game area 51 to the path of the launch ball. A part of the left side of the inner rail 8 and the return prevention valve 81 may be provided not on the game board 5 but on the mounting base 4.

  Then, the right side of the game board 5 is rotated backward with the hinge portion 47 as the center, and is fitted into the window portion 31. As a result, the upper portion of the game board 5 is fitted into the recessed portion 33 in a state where the bottom 53 is pushed upward by the protrusion 35 and the upper side 52 is in contact with the inside of the gaming machine frame 3. Furthermore, the game board 5 can be mounted on the gaming machine frame 3 without rattling by turning and clamping the clamp member 9.

  As described above, the gaming board 5 can be attached to the gaming machine frame 3 simply by inserting the gaming board 5 into the mounting base 4 and rotating backward, so that when the gaming board 5 is replaced, the mechanism board can be removed or removed from the ball tank. The replacement work can be easily performed without the need for a beading. At this time, since the firing rail 61 and the outer rail 7 are fixed at predetermined positions on the front surface 41 of the mounting base 4, the center positions of the rails are not shifted at all by exchanging the game board 5.
