Description

  The present invention relates to a game board support structure when replacing a game board of a ball game machine.

  As a pachinko machine, that is, a ball game machine, there is known a game board as shown in Patent Document 1 which is inserted into a holding part (support base part) and attached to a game machine frame. In this structure, a support base for holding the game board is rotatably provided on one side of the mounting base (game machine frame). After one end of the gaming board is inserted into the support base from the front surface of the gaming machine frame, the gaming board is fitted into an accommodation recess formed on the front surface of the gaming machine frame, and the pair of stopper members are rotated. The gaming board can be fixed to the gaming machine frame as described above.

  However, according to the above disclosure, since the launch rail (primary rail) in the ball launcher is disposed on the gaming machine frame side, and the outer rail (secondary rail) is disposed on the game board, There is a problem that the center position of the rails is likely to shift after the game board is inserted and the ball trajectory is not stable.

  Further, since the width (thickness) of the receiving hole of the support base is equal to the thickness of the game board, the bending of the game board cannot be absorbed. Since the longitudinal length of the socket is equal to the longitudinal length of the game board, the frictional resistance when the game board is inserted is large, so that it is difficult to attach and detach the game board. Since the insertion depth of the game board is not determined when the game board is inserted into the receptacle, the lateral position of the game board tends to vary. Since the vertical positioning of the game board is not performed when the game board is fitted into the housing recess, the vertical position of the game board is likely to be shifted. Furthermore, since the stopper member does not include a mechanism for absorbing fluctuations in the thickness of the game board, it has many problems that rattling tends to occur after the game board is tightened.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view showing a state in which the ball game machine of the present invention is opened, and includes a front frame 1 having a glass window 11, an outer frame 2 formed in a vertically long rectangular shape, and an outer frame 2 And a gaming machine frame 3 attached to be openable and closable inside. Inside the gaming machine frame 3, a support base 4 is pivotally mounted so as to be horizontally rotatable, and a game board 5 is inserted into the support base 4 from the side and held in a cantilever manner. 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 in which the support base 4 is disposed. The gaming machine frame 3 is provided with a window portion 31 for mounting the gaming board 5, and inside the gaming machine frame 3. A fitting recess 33 with a step 32 is formed on the upper side and the lower right. The upper and right ends of the game board 5 are fitted into the fitting recess 33. A plurality of ridges 35 are formed on the inner side of the lower side 34 of the gaming machine frame 3. The ridge 35 has a front half portion that is highly inclined toward the rear, and a second half portion that is formed flat. The lower side of the game board 5 is positioned by pushing the game board 5 fitted in the window 31 upward. And it has a structure to hold without rattling.

  3 and 4 show details of the support base 4. The support base 4 is formed by bending a front surface 41 formed of a metal plate and its upper and lower ends into a U-shape or the like toward the rear. Insertion groove 42. At the entrance of the insertion groove 42, a guide plate 45 formed by being bent obliquely outward from the entrance is provided in order to facilitate the insertion of the game board 5. Since only the upper end and the lower end of the game board 5 are inserted into the insertion groove 42, the friction resistance at the time of attachment / detachment can be reduced as compared with the conventional one in which the entire end of the game board is inserted. Replacement can be performed easily.

  A curved portion 44 is formed at the right end of the front surface 41 so as to correspond to a circular game area. Four screws 49 for fixing the ball launcher 6 are provided below the support base 4. The support base 4 has a left side plate 43, and the side plate 43 has protrusions 46 formed at least at two locations. When the end of the game board 5 comes into contact with the protrusion 46, the position of the game board 5 in the left-right direction is positioned.

  The length of the insertion groove 42 in the left-right direction is made as short as possible in comparison with the length in the left-right direction of the game board 5 in order to cope with poor attachment / detachment due to bending of the game board 5. The length of the insertion groove 42 may be a length that can hold the game board 5 in a cantilever manner. Further, the length of the insertion groove 42 in the front-rear direction is made about 1 mm thicker than the thickness of the game board 5 so that a slight play space is generated in order to cope with the variation in the thickness of the game board 5. Thereby, even if thickness becomes a little thick, the game board 5 can be inserted without trouble.

  In addition, the left end portion of the front surface 41 is provided with hinge portions 47 on the upper and lower sides, and these hinge portions 47 are mounted inside the gaming machine frame 3 so that the support base portion 4 can be rotated horizontally.

  As shown in FIG. 5, the front surface 41 of the support base 4 is provided with a launching device 6 and an outer rail 7 bent into 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 Plustech 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 which is the same plane, even when the game board 5 is replaced, the center position of the ball trajectory is shifted. There is no. In addition, as the ballistic device 62, instead of a linear motion type cage, a rotary type cage can be used.

  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 end 52 and a lower end 53, and an upper edge corner 54 and a lower edge corner 55 are cut into the respective end portions. The game board 5 can be attached to the support base 4 by inserting the insertion edge 42 from the right side while guiding the upper edge corner 54 and the lower edge corner 55 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.

  Clamp members 9 are disposed at corner portions of the gaming machine frame 3 (FIG. 11). The clamp member 9 includes a pressing member 91 that is provided in the fitting recess 33 and presses the game board 5 forward from the rear, and a rotation member 92 that rotates to pinch the game board 5 (FIG. 12). . The pressing member 91 includes a head 93 that is in contact with the back of the game board 5 and a spring 94 that repels the head 93 (FIG. 13). The rotating member 92 includes a shaft portion 95, a rotating piece 96 that is rotated by a finger, and a pressing surface 97 provided on the back side of the rotating piece 96. In the present embodiment, the clamp members 9 are provided at a total of three locations of the upper right corner, the lower right corner, and the upper left corner portion of the gaming machine frame 3, but may also be provided at the lower left corner portion. In that case, it is desirable to provide a back-and-forth backlash in the hinge portion 47 so that the support base 4 can be positioned in the front-back direction.

  In the gaming machine configured as described above, when the gaming board 5 is mounted, first, the left end of the gaming board 5 is inserted into the insertion groove 42 of the support base 4. As a result, the left end of the game board 5 is brought into contact with the protrusion 46 of the side plate 43 of the support base 4 to determine the position of the game board 5 in the left-right direction. Next, the right side of the game board 5 is rotated backward about the hinge portion 47 and fitted into the window portion 31. As a result, the upper end 52 of the game board 5 is fitted into the fitting recess 33, and the lower end 53 of the game board 5 is pushed upward along the inclination of the first half of the protrusion 35, and then the flat surface of the second half The lower end 53 is positioned. Since the game board 5 has a weight of several tens of kilograms, the vertical position of the game board 5 is fixed by positioning the lower end 53.

  Further, the game board 5 is fastened by the pressing member 91 and the rotation member 92 by turning the rotation member 92. Since the back surface of the game board 5 is pushed forward by the head 93 by the elastic force of the spring 94 and the front surface of the game board 5 is pressed by the pressing surface 97, the front surface of the gaming board 5 is based on the pressing surface 97. It can be mounted on the gaming machine frame 3 in the correct position without rattling.

  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 support 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 launch rail 61 and the outer rail 7 are fixed at predetermined positions on the front surface 41 of the support base 4, the center positions of the rails are not shifted at all by exchanging the game board 5.

  Furthermore, since the insertion port 42 of the game board 5 is arranged to be vertically opposed to be short, the insertion resistance of the game board 5 can be reduced. Since the protrusion 35 is provided on the lower side 34 of the gaming machine frame 3, the vertical position can be correctly fixed by positioning the lower end of the game board 5 with the protrusion 35. Since the side plate 43 and the protrusion 46 are provided on the support base 4, the lateral position of the game board 5 can be positioned. Since a play space is provided in the insertion groove 42, the frictional resistance when the game board 5 is attached and detached can be reduced, and the thickness variation of the game board 5 can be absorbed. Furthermore, the clamp member 9 can be fastened and fixed without absorbing a variation in the thickness of the game board 5.
