Description

  The present invention relates to a ball launcher mounting structure for launching a game ball upward from a ball launcher disposed on the lower left side of a gaming machine.

  In gaming machines such as pachinko machines, the lower left side of the gaming machine (left side of the ball tray) as described in, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2003-38736) for the purpose of expanding the gaming area. Some have adopted a vertical launching system in which a ball launching device is arranged and a game ball is launched almost vertically upward from this ball launching device. The ball launcher of Patent Document 1 has a configuration in which a hitting ball is arranged on the right side of a launch position of a launch pad (a position for holding a game ball to be fired next).

In general, the ball launcher is arranged on the back side of the front panel provided with a ball tray in a state of being attached and fixed to the main body frame from the back side or front side of the main body frame of the gaming machine, and the front panel is opened forward. By doing so, maintenance (cleaning, repair, inspection, etc.) of the ball launcher can be performed.
JP 2003-38736 A (page 3 etc.)

  By the way, in the configuration in which the front panel provided with the ball tray is opened forward to perform maintenance (cleaning, repair, inspection, etc.) of the ball launcher, the entire large front panel provided with the ball tray is opened forward. Since it is necessary to perform the maintenance work of the ball launcher in the state (that is, the state in which the entire large front panel protrudes forward), there is a drawback that the maintenance workability is poor because the front panel becomes an obstacle.

  Furthermore, when the ball launcher is attached or detached for repair or replacement, the ball launcher must be attached or detached with the entire large front panel opened forward in the configuration where the ball launcher is attached to the main body frame from the front side. On the other hand, in the configuration in which the ball launcher is attached to the main body frame from the back side, it is necessary to remove the back parts and the like arranged on the back side of the ball launcher. There is a disadvantage that the nature is bad.

  Further, as in Patent Document 1, in a vertical launch type gaming machine in which a ball launching device is disposed on the lower left side of the gaming machine, the left side of the trajectory of the game ball launched from the ball launching device (that is, the launch position) A foul ball recovery port is provided on the upper left side. However, in the configuration where the ball launcher of the ball launcher is placed to the right of the launch position, the placement space for the ball launcher is to the right of the launch position. There is a problem that the space below the mouth (that is, to the left of the launch position) is not used effectively.

  Further, in a vertical launch type gaming machine in which a ball launcher is arranged on the lower left side of the gaming machine, when the ball launcher of the ball launcher is arranged on the right side of the launch position, the space for placing the ball launcher becomes the launch position. When the game machine is installed in a game hall such as a pachinko hall, the game machine installation mechanism will be placed in the lower center of the back side of the game machine. Depending on the specifications (size, shape, etc.) of the ball collection mechanism, the out ball collection mechanism may interfere with the ball launching device.

  The present invention has been made in consideration of these circumstances. Accordingly, the object of the present invention is to improve the maintenance and detachability of a ball launcher in a vertical launch game machine, It is an object of the present invention to provide a mounting structure for a ball launcher capable of solving the problems relating to the arrangement space of the launcher.

  In order to achieve the above object, the invention according to claim 1 is a ball launching device in which a ball launching device is arranged on the left side of a ball receiving plate provided at the lower part of the gaming machine, and a game ball is launched upward from the ball launching device. In the mounting structure, the ball launching device has a mounting base portion, a launch seating portion that holds the game ball in the launch position, a hitting ball member that hits the game ball held in the launch position, and a rotational drive of the hit ball member And a stopper part for restricting the rotation range of the hitting ball member are integrally provided, and the rotation axis of the hitting ball member is arranged to the left of the launch position, and the front side of the ball launching device A front member that covers the ball is provided so as to be openable and closable separately from the ball tray, and the ball launcher is attached so that the ball launcher can be detached from the front of the gaming machine when the front member is opened. It is what.

  In this configuration, the front member that covers the front side of the ball launcher is provided so that it can be opened and closed separately from the ball tray, so a relatively small front member provided separately from the ball tray is opened forward. It is possible to perform the maintenance work of the ball launcher from the front by simply doing this, and the maintenance workability of the ball launcher can be improved.

  Moreover, since the ball launcher can be removed from the front when the front member is opened, the ball launcher can be removed from the front simply by opening the relatively small front member forward. It is possible to improve the workability of the ball launcher.

  In addition, in a vertical launch type gaming machine in which a ball launching device is arranged on the lower left side of the gaming machine, a foul ball recovery port is located on the left side of the trajectory of the game ball launched from the ball launching device (that is, on the left side above the launch position). However, since the rotation axis of the ball striking member is arranged to the left of the firing position, the placement space of the ball launching device can be shifted to the left with respect to the firing position, thereby collecting the foul ball. The space below the mouth can be effectively used as the space for arranging the ball launching device.

  Furthermore, since the rotation axis of the ball striking member is arranged to the left of the firing position, the space for placing the ball launching device can be shifted to the left (that is, outside the gaming machine) with respect to the firing position. For this reason, when a gaming machine is installed in a game hall such as a pachinko hall, various specifications (size, shape, etc.) of the out-ball collecting mechanism on the gaming machine installation mechanism side that is arranged in the lower center on the back side of the gaming machine On the other hand, the out-ball collecting mechanism can be prevented from interfering with the ball launching device.

  Further, as in the present invention, in the configuration in which the front member provided separately from the ball tray is opened forward to perform maintenance and removal of the ball launcher, the ball storage space of the ball tray is expanded to the left. If the ball tray covers the front side of the ball launcher, the maintenance and removal workability of the ball launcher will be impaired, but in the present invention, the rotation axis of the hitting member is to the left of the launch position. By arranging the ball launcher, the placement space of the ball launcher can be shifted to the left with respect to the launch position (that is, the outside of the gaming machine), so that the ball catcher does not cover the front side of the ball launcher. The ball storage space can be expanded to the left, and there is also an advantage that the storage amount of the ball tray can be increased without impairing the maintenance and removal workability of the ball launcher.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, based on FIG.1 and FIG.2, the schematic structure of the front side lower part of a pachinko machine is demonstrated. As shown in FIG. 1, an upper ball receiving tray 12 and a lower ball receiving tray 13 for receiving pachinko balls (game balls) are arranged side by side in the lower part on the front side of the main body frame 11 of the pachinko machine (game machine). Pachinko balls (prize balls) paid out from a payout device (not shown) flow down the ball payout passage (not shown) and flow into the upper ball tray 12 and exceed the amount stored in the upper ball tray 12. The surplus pachinko balls flow down the overflow passage (not shown) and flow into the lower ball tray 13.

  In addition, a ball launcher 14 that launches a pachinko ball supplied from the upper ball tray 12 is disposed at the lower left part of the main body frame 11 (to the left of the ball trays 12 and 13). A pachinko ball is launched almost vertically upward (or obliquely upward) from the lower left side of the. In front of the ball launcher 14, a left front door 15 (front member) that covers the front side of the ball launcher 14 is provided separately from the ball trays 12 and 13 so as to be opened and closed. On the other hand, a launch operation handle 16 of the ball launcher 14 is provided at the lower right side of the main body frame 11 (to the right of the ball trays 12 and 13).

  As shown in FIG. 2, the left front door 15 is attached to the main body frame 11 via a hinge mechanism or the like (not shown) so that it can be opened and closed. The front side of 14 can be exposed and maintenance (cleaning, repair, inspection, etc.) of the ball launcher 14 can be performed. Furthermore, when the left front door 15 is opened forward, the ball launcher 14 is attached to the main body frame 11 from the front side so that the ball launcher 14 can be detached from the front with respect to the pachinko machine.

  Further, a rectifier 17 is provided on the back surface of the left front door 15 to send out the pachinko balls one by one to the ball launcher 14, and the pachinko balls in the upper ball tray 12 are connected to the connection channel provided in the left front door 15. 18 flows into the rectifier 17 and is supplied from the rectifier 17 to the ball launcher 14. Further, the left front door 15 is provided with an upstream portion of a ball discharge channel 19 through which a pachinko ball flowing down from the upper ball tray 12 flows down to the lower ball tray 13 when a ball release lever (not shown) is operated. It has been.

  Further, above the ball launcher 14 in the main body frame 11, wiring of electrical parts such as a rectifier 17, an operation button, and a display (both not shown) provided on the left front door 15 is provided on the main body frame 11. A wiring hole 20 is formed for drawing out to the back side. As a result, the wiring on the left front door 15 side can be collectively pulled out from the wiring hole 20 to the back side of the main body frame 11, and the wiring on the left front door 15 side is prevented from protruding around the movable part of the ball launcher 14. I can do it. Further, the main body frame 11 is provided with one or a plurality of engagement lock portions 21 for holding the left front door 15 in a closed state when the left front door 15 is closed.

Next, the configuration of the ball launching device 14 will be described with reference to FIGS. 3 and 4.
As shown in FIG. 3, the mounting board 22 (mounting base part) of the ball launching device 14 is formed of a metal such as aluminum, for example. It is fixed. The launch seat 23 is formed with a ball introduction portion 25 for introducing a pachinko ball supplied from the rectifier 17, and a launch ball guide portion 26 having a substantially V-shaped cross section is provided to the left of the ball introduction portion 25. It has been. The position where the lower part of the pachinko ball is fitted in the gap between the launching ball guide part 26 and the receiving part 27 formed below the ball introducing part 25 and the pachinko ball is stationary is the launch position of the pachinko ball. Become.

  On the left side of the launch seat 23 on the front surface of the mounting substrate 22, a hitting ball 28 (hit ball member) for launching a pachinko ball is rotatably provided. By hitting the pachinko ball received at the launch position of the launch seat 23 from below with the hitting ball portion 29 provided at the tip of the hitting ball rod 28, the pachinko ball enters the launch passage 30 (see FIG. 2). It is designed to be launched almost vertically upward (or diagonally upward).

  As shown in FIG. 4, a rotary solenoid 31 (drive source) for rotationally driving the hitting ball 28 is attached to the back surface of the mounting substrate 22, and a rotary shaft 32 (see FIG. 3) of the rotary solenoid 31. Protrudes to the front side of the mounting substrate 22, and a ball striking rod 28 is fastened and fixed to the front end portion of the rotating shaft 32 with a bolt 33.

  In the present embodiment, as shown in FIG. 3, the hitting ball 28 so that the rotation axis of the hitting ball 28 (that is, the rotation shaft 32 of the rotary solenoid 31) is located to the left of the firing position of the firing seat 23. And the rotary solenoid 31 are arranged so that the arrangement space of the ball launching device 14 (that is, the placement space of the mounting board 22) is shifted to the left (that is, outside the pachinko machine) with respect to the launch position of the launch seat 23. ing.

  Further, a stopper rubber 34 (stopper portion) for restricting the rotation range of the hitting ball 28 is disposed below the rotation axis of the hitting ball 28 on the front surface of the mounting substrate 22, and the stopper rubber 34 is supported and fixed. A bracket 35 is fixed to the mounting substrate 22 with screws 36. As shown by a solid line in FIG. 3, the position at which the hitting ball 28 is rotated downward about the rotation axis by its own weight (or urging force of a spring or the like) and is in contact with the right side surface of the stopper rubber 34. 28 is the initial position.

  When the firing operation handle 16 is fired, energization / disconnection of the rotary solenoid 31 is repeated with a voltage corresponding to the operation amount. Thereby, as shown by a two-dot chain line in FIG. 3, the hitting ball 28 rotates from the initial position around the rotation axis in the firing direction (counterclockwise in FIG. 3), and After launching the pachinko ball received at the launch position by the hitting portion 29, as shown by the solid line in FIG. 3, the launch operation is rotated in the direction opposite to the launch direction (clockwise in FIG. 3) and returned to the initial position. repeat.

  The striking ball 28 is integrally provided with a stopper piece 37 protruding in the outer diameter direction from the vicinity of the rotation axis thereof, and the striking ball 28 rotates in the firing direction as shown by a two-dot chain line in FIG. When moved, the stopper piece 37 comes into contact with the left side surface of the stopper rubber 34 so that the maximum rotation position of the hitting ball 28 in the firing direction is regulated.

  Further, in the present embodiment, the hitting ball rod 28 is arranged so that the rotation axis of the hitting ball rod 28 is located below the firing position of the firing seat 23. In this way, since the launch position of the launch seat 23 is positioned above the pivot axis of the hitting ball 28, the initial position of the hitting ball 28 is rotated upward (in a direction approaching horizontal) accordingly. As a result, the height dimension from the launch position of the launch seat 23 to the lowest end of the ball launcher 14 can be reduced, and the ball launcher 14 can be miniaturized.

  By the way, when the hitting ball 28 is rotated upward in a state where the pachinko ball is placed on the hitting ball 28, the pachinko ball placed on the hitting ball 28 and the launching seat 23 collide with force, and the launching seat 23 and the hitting ball 28 are hit. There is a risk of damage. Further, when the pachinko ball placed on the hitting ball 28 collides with the firing seat 23, the tip of the hitting ball 28 may not reach the normal hitting point, or the firing accuracy may not be stable.

  Further, since the weight of the hitting ball 28 changes when the pachinko ball is placed on the hitting ball 28, there is a possibility that the firing accuracy of the pachinko ball becomes unstable.

  In addition, in the case of the vertical launching type ball launching device 14 that launches the pachinko ball almost vertically upward, the hitting ball 28 has a substantially square shape with a concave portion on the inside due to its structure. When pushing forward, there will be a space in which one pachinko ball fits.

  Therefore, in order to prevent the pachinko balls from being placed on the hitting ball 28 or to appropriately remove the pachinko balls placed on the hitting ball 28, an outwardly inclined surface is formed on the inner side of the hitting ball 28 bent in a substantially square shape. You may make it provide the ball | bowl mounting prevention mechanism which has. Alternatively, a ball placement prevention mechanism is provided on the launch seat 23 side, and when the hitting ball 28 is rotated upward with the pachinko ball placed, the pachinko ball is removed outward by the ball placement prevention mechanism. You may comprise.

  Since the ball launching device 14 configured as described above is integrated with one mounting substrate 22 by assembling main components such as the launch seat 23, the hitting ball 28, the rotary solenoid 31, and the stopper rubber 34, An arrangement error (dimensional error) between the parts can be reduced, the launch performance can be stabilized, and the ball launcher 16 can be easily stored.

  As shown by the arrows in FIG. 2, the pachinko ball launched from the ball launcher 14 passes through the launch passage 30 and then passes through the guide passage 40 formed between the outer rail 38 and the inner rail 39. It is driven above the game area (not shown) of the board. Further, to the left of the orbit of the pachinko ball launched from the ball launcher 14 (that is, the upper left side of the launch position of the launch seat 23), the game area of the pachinko balls launched from the ball launcher 14 is reached. A foul ball collection port 41 is provided for receiving a foul ball that returns to the guide passage 40 without being able to do so.

  In the present embodiment described above, the left front door 15 covering the front side of the ball launcher 14 is provided so as to be opened and closed separately from the ball trays 12 and 13, and therefore separate from the ball trays 12 and 13. The maintenance work of the ball launcher 14 can be performed from the front by simply opening the relatively small left front door 15 provided in the above, and the maintenance workability of the ball launcher 14 can be improved.

  Moreover, since the ball launcher 14 can be attached to and detached from the front of the pachinko machine when the left front door 15 is opened, it is possible to launch the ball from the front simply by opening the relatively small left front door 15 forward. The device 14 can be detached and the workability of the ball launcher 14 can be improved.

  Further, in the vertical launch pachinko machine in which the ball launcher 14 is disposed on the lower left side of the pachinko machine, it is located on the left side of the orbit of the pachinko ball launched from the ball launcher 14 (that is, above the launch position of the launch seat 23). A foul ball collection port 41 is provided on the left side, and the ball striking rod 28 is positioned so that the rotation axis of the ball striking rod 28 (that is, the rotation shaft 32 of the rotary solenoid 31) is located to the left of the firing position of the firing seat 23. Since the rotary solenoid 31 is arranged, the arrangement space of the ball launching device 14 (that is, the arrangement space of the mounting board 22) can be shifted to the left with respect to the firing position of the firing seat portion 23. The space below the ball collection port 41 can be effectively used as the space for arranging the ball launcher 14.

  Further, since the ball striking rod 28 and the rotary solenoid 31 are arranged so that the rotation axis of the ball striking rod 28 is located to the left of the firing position of the firing seat 23, the space for placing the ball launching device 14 is launched. It can be set to the left (that is, outside the pachinko machine) with respect to the launch position of the seating portion 23. For this reason, when a pachinko machine is installed in a game hall such as a pachinko hall, various specifications (size, shape, etc.) of the out-ball collecting mechanism on the gaming machine installation mechanism side that is arranged at the lower center of the back side of the pachinko machine In contrast, it is possible to prevent the out-ball collecting mechanism from interfering with the ball launching device 14.

  In the configuration in which the left front door 15 provided separately from the ball trays 12 and 13 is opened forward and the ball launcher 14 is maintained and removed as in this embodiment, the upper ball tray 12 and the lower If the ball storage space of the ball receiving tray 13 is expanded to the left and the upper ball receiving tray 12 and the lower ball receiving tray 13 cover the front side of the ball launching device 14, the maintenance and workability of the ball launching device 14 are impaired. However, in this embodiment, by arranging the rotation axis of the ball striking rod 28 to the left of the firing position of the launch seat 23, the space for placing the ball launcher 14 is set to the launch position of the launch seat 23. Since the upper ball tray 12 and the lower ball tray 13 do not cover the front side of the ball launcher 14, the upper ball tray 12 and the lower ball tray 13 can be moved to the left (that is, outside the pachinko machine). Left the ball storage space It is possible to expand the, without impairing the workability of maintenance and desorption of the sphere launcher 14, there is an advantage that it is possible to increase the reservoir volume of the upper ball pan 12 and the lower ball pan 13.

  In the above embodiment, the present invention is applied to a two-plate pachinko machine in which an upper ball tray 12 and a lower ball tray 13 are provided in the lower front portion of the pachinko machine, but one ball tray is provided in the lower front portion of the pachinko machine. The present invention may be applied to a single-plate pachinko machine provided with only one plate.

  The scope of application of the present invention is not limited to general pachinko machines, and the present invention may be applied to various gaming machines in which a ball launcher is disposed on the lower left side of the gaming machine, such as an arrangement ball gaming machine. .
