Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine.

  In a ball game machine such as a pachinko machine, the game ball launched by the launching means is guided to the upper side of the game area through a launch guide passage formed between the outer rail and the inner rail, for example. Furthermore, in the vicinity of the exit from the launch guide passage to the game area, return ball prevention means for allowing the game ball to pass in the launch direction and preventing the game ball from passing in the return direction is arranged to temporarily play the game. The game ball that has entered the area is prevented from returning to the firing guide passage side.

This return ball prevention means can be rotated around the rotation axis in the front-rear direction between a closed state in which the exit from the launch guide passage to the game area is substantially closed and an open state in which the exit from the closed state is opened in the direction of passing the shot ball And a supporting means for rotatably supporting the opening / closing portion and the weight portion, and a weight portion that is rotatably provided integrally with the opening / closing portion and urges the opening / closing portion to the closing side. (For example, Patent Document 1).
JP 2004-329298 A

  In the return ball prevention means described in Patent Document 1, since the vicinity of the rotation axis of the opening / closing part is exposed to the firing guide passage side, the shot ball frequently collides with the rotation axis immediately before reaching the exit, There is a possibility that the opening / closing portion cannot be smoothly rotated due to, for example, the rotation shaft being bent due to long-term use.

  Further, in recent ball game machines, the liquid crystal display arranged in the game area has been enlarged, and the game ball movable area particularly on the side of the liquid crystal display has become very narrow. In such a situation, it is necessary to dispose the return ball prevention means on the upper side of the game area as much as possible so that the return ball prevention means does not further limit the game ball movable area.

  However, if the arrangement position of the return ball prevention means moves upward as described above, the inclination angle of the tip end portion of the inner rail is reduced by that amount. Therefore, when the return ball prevention means described in Patent Document 1 is employed as it is. In some cases, the game ball may stop between the return ball prevention means and the inner rail.

  In view of such a conventional problem, the present invention can maintain smooth rotation of the opening / closing part even after long-term use, and even if the return ball preventing means is arranged on the upper side of the game area, An object of the present invention is to provide a bullet ball game machine in which game balls do not stop at the portion.

  The present invention is directed to a launching means 8 for launching a game ball, and a game ball formed between the outer rail 13 and the inner rail 14 and launched by the launching means 8 toward the game area 12 on the front side of the game board 11. And a return ball that is disposed in the vicinity of the exit 22 from the launch guide passage 21 to the game area 12 and that allows the game ball to pass in the launch direction and prevents the game ball from passing in the return direction. The return ball prevention means 23 is provided around the rotational axis 35 in the front-rear direction between a closed state in which the outlet 22 is substantially closed and an open state in which the outlet 22 is opened in the direction of the passing of the launch ball. In the ball game machine, comprising: a rotatable opening / closing portion 31, a biasing portion 37 for biasing the opening / closing portion 31 toward the closing side, and a support member 33 for rotatably supporting the opening / closing portion 31. Tip 1 of inner rail 14 The cover portion 44 for closing substantially between the opening and closing portion 31 of the closed state and a, are those arranged along the extension line of the inner rail 14.

  According to the present invention, since the launch ball does not directly collide with the rotating shaft 35 and an excessive force in the bending direction acts on the rotating shaft 35, the opening / closing portion 31 can rotate smoothly even after long-term use. Can be maintained. Further, it is possible to reliably prevent the game ball from stopping between the return ball preventing means 23 and the inner rail 14. In addition, since the return ball prevention means 23 can be arranged upward by the amount of the cover portion 44, there is also an advantage that a wider game ball movable area can be secured in the side area of the game area.

In addition, the inner rail 14 is disposed on the inner side so as to be parallel to the outer rail 13 from the upper left of the game board 11 to the substantially horizontal center on the lower side, and further to the vicinity of the right edge of the game board 11 as it is. It extends in an arc.

  As described above, the inner rail 14 and the outer rail 13 are arranged inside and outside at a predetermined distance from each other in the left portion of the game board 11, and the parallel portion guides the game ball toward the game area 12. It becomes the discharge guide passage 21 to be. Further, in the vicinity of the exit 22 from the launch guide passage 21 to the game area 12, return ball prevention means 23 for preventing the return of the game ball from the game area 12 side to the launch guide path 21 side is disposed.

  The center case 15 is disposed substantially at the center of the game area 12, and constitutes a display window 25 for a liquid crystal display (image display means) 24 mounted on the back side of the game board 11, for example, as shown in FIG. Display frame body 26, stage means 27 arranged on the lower side of the display frame body 26, ball guidance means 28 provided on the display frame body 26 for guiding a game ball to the stage means 27, and the like.

  Note that a flange portion 26 a that projects outward is integrally provided at the peripheral edge of the display frame body 26, and the center case 15 is in a state in which the flange portion 26 a is in contact with the front side of the game board 11. For example, it is detachably fixed by screwing.

  The return ball preventing means 23 allows the game ball to return from the game area 12 side to the discharge guide passage 21 side by allowing the game ball to pass in the discharge direction at the outlet 22 and preventing the game ball from passing in the return direction. As shown in FIGS. 3 to 7, a movable member 32 having a plate-like opening / closing portion 31 that opens and closes the outlet 22 and a support member 33 that rotatably supports the movable member 32 are provided. Yes.

  The support member 33 includes a plate-like base member 34 that extends along the front side of the game board 11 and a support pin (rotating shaft) 35 that projects from the front side of the base member 34 and rotatably supports the movable member 32. Provided so that the support pin 35 is located on the game area 12 side in the vicinity of the distal end portion 14a of the inner rail 14 so that the support pin 35 is located slightly on the game area 12 side with respect to the extension line of the inner rail 14. It is detachably fixed to.

  The movable member 32 is made of, for example, a synthetic resin and includes a cylindrical portion 36 having a shaft hole 36a through which the shaft portion 35a of the support pin 35 is inserted as shown in FIG. An open / close portion 31 and a weight portion (biasing portion) 37 are provided, for example, integrally projecting outward from the substantially radial direction.

  The opening / closing portion 31 is, for example, a thin plate shape whose thickness is smaller than the outer diameter of the cylindrical portion 36, and is disposed so as to be substantially upward with respect to the support pin 35, and has a predetermined angle around the support pin 35. By rotating in the range, it is possible to change between a closed state in which the outlet 22 is substantially closed and an open state in which the outlet 22 is opened in the direction in which the projecting ball passes.

  In the closed state shown in FIG. 3, the opening / closing part 31 protrudes toward the outlet 22 at an angle shallower than a right angle with respect to the direction in which the launch ball passes, and the distance between the tip side and the outer rail 13 is at least outside the game ball. It is comprised so that it may become smaller than a diameter. As a result, the game ball to be returned from the game area 12 side to the launch guide passage 21 side is a surface on the game area 12 side (hereinafter referred to as a return ball contact surface 31a) with respect to the opening / closing portion 31 in the closed state. And returned to the game area 12 side.

  Further, as shown in FIG. 4, the opening / closing unit 31 rotates in the direction in which the projecting ball passes, that is, in the clockwise direction, when the projecting ball collides with a surface on the firing guide passage 21 side (hereinafter referred to as the projecting ball contact surface 31b). And it changes from a closed state to an open state. In this open state (indicated by a solid line in FIG. 4), the distance between the distal end side of the opening / closing part 31 and the outer rail 13 is at least larger than the outer diameter of the game ball, and the passage of the shot ball to the game area 12 side is prevented. Permissible.

  Note that the return ball contact surface 31a of the opening / closing portion 31 is tapered at the tip side, and when the opening / closing portion 31 is in a closed state, the game ball that contacts the return ball contact surface 31a side can be smoothly smoothed. Guides you downward.

  The weight part 37 urges the opening / closing part 31 toward the closing side, and has a thickness substantially the same as the outer diameter of the cylindrical part 36, for example, and protrudes on the opposite side of the opening / closing part 31 with respect to the cylindrical part 36. Yes.

  As shown in FIG. 7, for example, a weight mounting hole 37a is formed in the weight portion 37 from the back side to the front, and a metal weight 38 formed in a columnar shape, for example, is formed in the weight mounting hole 37a. It is press-fitted.

  The arrangement angle of the opening / closing part 31 and the weight part 37 with respect to the cylindrical part 36 is such that, when the opening / closing part 31 is in the closed state shown in FIG. Is also set so as to come to a position slightly swung in the open side rotation direction, that is, clockwise.

  Further, the opening / closing part 31 is provided so as to be deviated to one side with respect to the central axis of the cylindrical part 36 so that the projecting ball contact surface 31b is substantially in contact with the outer peripheral surface of the cylindrical part 36. The ball contact surface 31 b is smoothly connected to the outer surface of the weight portion 37.

  The support member 33 that rotatably supports the movable member 32 includes the base member 34 and the support pins 35 as described above. The base member 34 is made of, for example, a synthetic resin, and has a plate-like fixing plate 41 arranged along the front side of the game board 11, a pin fixing base 42 protruding from the front side of the fixing plate 41, and a lower cover A portion 43 and an upper cover portion (cover portion) 44 are integrally provided.

  A plurality (for example, two) of fixing holes 41a are formed in the fixing plate 41, and a plurality of (for example, two) positioning protrusions 41b (FIG. 5) are integrally provided on the back surface side. In a state where the positioning protrusion 41b is fitted and positioned in a positioning hole (not shown) on the game board 11 side, it is detachably fixed to the front side of the game board 11 by a fixing screw 41c through the fixing hole 41a. It has become.

  The pin fixing base 42 fixes the support pin 35, and has a substantially cylindrical shape including a front-rear direction insertion hole 42 a into which the support pin 35 is inserted from the front side, and is integrally formed so as to protrude slightly forward from the fixing plate 41. Is formed. A concave portion 32a corresponding to the pin fixing base portion 42 is formed on the movable member 32 side.

  The lower cover portion 43 covers a part of the movable member 32 from the lower side, that is, from the game area 12 side. Of the outer peripheral surfaces of the cylindrical portion 36 and the weight portion 37 with respect to the movable member 32 in the closed state, The front area is substantially C-shaped so as to cover approximately half of the game area 12 side, and protrudes from the front side of the fixed plate 41.

  Further, the lower cover portion 43 has a closing direction restricting portion 45 that abuts on the weight portion 37 side when the movable member 32 is in a closed state and restricts the rotation operation in the closing direction, for example, protrudes toward the inner surface side. It is installed.

  Further, the upper end portion of the lower cover portion 43 is brought into contact with the return ball contact surface 31a side of the opening / closing portion 31 when the movable member 32 is in the open state, and the opening direction restricts the rotation operation in the opening direction. The restriction part 46 is configured. In the following description, a state (indicated by a one-dot chain line in FIG. 4) when the rotation operation is restricted by the opening direction restricting portion 46 among the open states is particularly referred to as a fully open state.

  The upper cover portion 44 substantially closes the gap between the front end portion 14 a of the inner rail 14 and the closed opening / closing portion 31, and is disposed on the opposite side of the lower cover portion 43 with respect to the movable member 32. Projected to the front.

  The upper cover portion 44 is formed in a plate shape, the rear end portion 44a in the firing direction is located in the vicinity of the front end portion 14a of the inner rail 14, and the front end portion 44b in the firing direction is the firing ball contact surface 31b of the opening / closing portion 31. Is disposed so that the rear end portion 44a side in the firing direction has a low inclination along the extension line of the inner rail 14 so as to be positioned in the vicinity of the inner rail 14.

  Moreover, the edge of the firing direction front end portion 44b of the upper cover portion 44 is formed in a taper shape, and the taper surface 47 on the upper surface side is inclined so that the rear end side in the firing direction is lower than the front end side.

  Note that the pin fixing base 42 and the lower cover portion 43 are connected to each other and the pin fixing base 42 and the upper cover portion 44 are connected to each other by connecting ribs 48 provided integrally along the fixing plate 41.

  Next, the return ball prevention operation by the return ball prevention means 23 described above will be specifically described. Since the movable member 32 is rotatably supported by the support pin 35, the return ball preventing means 23 is movable when the weight portion 37 tries to move to the lower side of the support pin 35 by its own weight in the normal state. The member 32 is biased counterclockwise, that is, in the closing direction, and the opening / closing portion 31 is in a closed state in which the outlet 22 is substantially closed (FIG. 3).

  In this closed state, the weight portion 37 abuts against the closing direction restricting portion 45 at a position slightly swung in the clockwise direction with respect to the support pin 35 from below vertically, so that the movable member 32 is stable in the closed state. Retained.

  When the player operates the launch handle 8a and the launch means 8 launches a game ball based on the manipulated handle, the launch ball is guided upward along the outer rail 13 in the launch guide passage 21 and reaches the exit 22. Then, it comes into contact with the projecting ball contact surface 31b of the opening / closing part 31 in the closed state.

  The launch ball that has come into contact with the opening / closing portion 31 receives a reaction force from the biasing force of the weight portion 37 from the opening / closing portion 31, but when the launch ball still maintains a sufficient speed, it resists the biasing force. Proceed in the launch direction. In this case, the opening / closing part 31 is pushed by the firing ball and rotates in the opening direction, that is, clockwise, and eventually the opening state in which the distance between the outer rail 13 and the distal end side of the opening / closing part 31 is larger than the outer diameter of the game ball. Thus, since the passage of the launch ball is permitted, the launch ball passes through the outlet 22 and enters the game area 12 (FIG. 4).

  In many cases, when the projecting ball comes into contact with the opening / closing part 31, the movable member 32 rotates to the fully open state indicated by the alternate long and short dash line in FIG. 4. When the fully opened state is reached, the return ball contact surface 31a side of the opening / closing part 31 comes into contact with the opening direction restricting part 46 on the lower cover part 43 side and its rotation is restricted.

  When the projecting ball passes through the outlet 22, the movable member 32 quickly rotates in the closing direction, that is, counterclockwise by the biasing force of the weight portion 37, and returns to the closed state (FIG. 3).

  Further, when the game ball is launched at a sufficient initial speed, the shot ball travels along the outer guide rail 13 while receiving a large centrifugal force, so that the shot ball passes through the outlet 22. In other words, the ball prevention means 23 does not come into contact with any part other than the opening / closing part 31.

  However, since the game ball fired at an insufficient initial speed receives a small centrifugal force while traveling in the firing guide passage 21, the game ball is separated from the outer rail 13 before reaching the outlet 22, for example, to the return ball prevention means 23. There may be a collision. Even in this case, in the return ball preventing means 23 of the present embodiment, since the upper cover portion 44 substantially blocks the space between the front end side of the inner rail 14 and the opening / closing portion 31, the fired ball is directly applied to the cylindrical portion 36 or the like. There is no collision. Therefore, an excessive force in the bending direction does not act on the support pin 35, and the smooth rotation of the opening / closing part 31 can be maintained even after long-term use.

  Further, the upper cover portion 44 is disposed on the inner rail 14 side in an inclined shape along the extension line of the inner rail 14, and the tapered surface 47 provided at the end edge of the firing direction front end portion 44 b also has the inner rail 14. Since the side is formed with a low slope, the game ball is stopped between the return ball prevention means 23 and the inner rail 14 even though the return ball prevention means 23 is arranged on the upper side of the game area 12. Can be surely prevented.

  In addition, since the return ball prevention means 23 can be disposed upward by the upper cover portion 44, there is an advantage that a wider game ball movable area on the side of the center case 15 can be secured.

  A game ball that has passed through the outlet 22 and entered the game area 12 may be bounced by a game nail or the like to return to the outlet 22 side and come into contact with the closed opening / closing part 31. In this case, the movable member 32 has its weight portion 37 abutting against the closing direction restricting portion 45 to restrict the counterclockwise rotation, and the distance between the outer rail 13 and the front end side of the opening / closing portion 31 is a game ball. Therefore, the game ball is guided to the lower game area 12 side along the return ball contact surface 31a of the opening / closing part 31, and does not return to the firing guide passage 21 side (FIG. 3). .

  In addition, since the movable member 32 has a substantially half of the outer peripheral surfaces of the cylindrical part 36 and the weight part 37 on the game area 12 side covered by the lower cover part 43, the game ball on the game area 12 side is also cylindrical. There is no direct collision with the part 36 or the like. Therefore, an excessive force in the bending direction does not act on the support pin 35, and the smooth rotation of the opening / closing part 31 can be maintained even after long-term use.

  FIG. 8 exemplifies the second embodiment of the present invention, and shows an example in which an opening direction restricting portion 46 for restricting the rotation operation of the movable member 32 in the opening direction is provided on the upper cover portion 44 side.

  As shown in FIG. 8, in this embodiment, the opening direction restricting portion 46 is integrally formed, for example, in a protruding shape on the lower surface side of the upper cover portion 44, that is, the game area 12 side, and the movable member 32 is in the open state. At this time, the weight portion 37 comes into contact with the opening direction restricting portion 46 and restricts the rotation operation in the opening direction. Other configurations are the same as those of the first embodiment.

  As described above, when the opening / closing part 31 is in the open state, the weight part 37 abuts on the upper cover part 44 side to restrict its rotation, so that the launch ball collides with the opening / closing part 31. Thus, when the movable member 32 rotates to the open state, the stress generated near the base of the opening / closing portion 31 can be dispersed, and fatigue of the return ball preventing means 23 due to long-term use can be reduced.

  FIG. 9 illustrates the third embodiment of the present invention, and shows an example in which the support member 33 is provided integrally with the center case 15.

  As shown in FIG. 9, the flange portion 26 a on the center case 15 side and the fixed plate 41 of the support member 33 on the return ball prevention means 23 side are plate-like connections arranged along the front side of the game board 11. The plates 51 are integrally connected.

  With such a configuration, there is an advantage that the number of parts can be suppressed and the assembling work can be made more efficient.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the return ball preventing means 23 may be configured to be mounted not on the game board 11 but on the inner rail 14 or the front frame 3 side, for example. Moreover, the mounting method is arbitrary. For example, when the return ball preventing means 23 is fixed to the game board 11 as in the embodiment, it may be fixed by press-fitting or the like.

  For example, the upper cover 44 may be configured such that the angle around the front-rear axis with respect to the fixed plate 41 can be adjusted. Thereby, even if the arrangement position of the return ball prevention means 23 changes for every model, the upper cover part 44 can be set to an optimal angle according to the angle of each inner rail 14 or the like.

  In the embodiment, an example in which the outer rail 13 and the inner rail 14 are mounted on the front side of the game board 11 has been shown, but at least one of the outer rail 13 and the inner rail 14 may be provided on the front frame 3 side.

  The urging portion that urges the opening / closing portion 31 toward the closing side may be constituted by, for example, a spring member or the like.

  Furthermore, in the embodiment, an example in which the present invention is applied to a pachinko machine has been shown, but it goes without saying that the present invention can be similarly applied to various ball game machines such as an arrange ball machine.
