  However, since the conventional pachinko machine has a structure in which main parts of the ball launcher are exposed when the front panel is opened, a tool or the like is mistakenly in maintenance work in a place other than the ball launcher. There is a risk of hitting the main parts and damaging the main parts. In addition, falling balls (foul balls) that return to the ball launcher during the game, and foreign objects that are accidentally dropped during maintenance work enter the gaps in the movable area of the batting cage, causing the ball launcher to function properly. There is also a risk that it will become impossible to operate.

  It is an object of the present invention to improve a pachinko machine configured such that at least main parts of a ball launcher are exposed when the front panel is opened.

The present invention comprises a ball launcher that launches a pachinko ball from the lower left side of the pachinko machine substantially vertically upward, and a front panel that opens and closes the front side of the main body frame of the pachinko machine, and the ball launch when the front panel is opened. In the pachinko machine configured to expose at least main parts of the device, the ball launching device includes a ball introducing unit that introduces a pachinko ball for launching into a launch position, and a pachinko ball introduced by the ball introducing unit. A replenishment guide rail that determines the launch position of the ball, and a batting ball that strikes and fires a pachinko ball at the launch position,
A protective cover that protects at least the front side of the hitting ball in the initial position is provided on the front side of the ball launcher, and the left end of the protective cover is attached to the main body frame via a hinge mechanism, and the protection The cover is configured to be openable and closable around the hinge axis of the hinge mechanism, and the opening corresponding to the part of the protective cover corresponding to the sphere introduction part exposes the sphere introduction part to the front side. Formed into
On the back surface of the front panel, a ball sending device having a sending cam for sending a pachinko ball to the ball introducing portion in synchronization with the launching operation of the ball launching device faces the ball launching device with the protective cover interposed therebetween. The rear end portion of the delivery cam is inserted into the opening portion of the protective cover.

  In this configuration, the main parts such as the ball hitting basket of the ball launcher are covered with the protective cover, so when the front panel is opened, the tool hits the main parts of the ball launcher or has fallen near the ball launcher. It is possible to prevent a pachinko ball or a foreign object from entering the gap in the ball launching device.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the configuration of the front side of the pachinko machine will be schematically described with reference to FIG. A game board 12 is attached to the main body frame 11 of the pachinko machine, and the game board 12 is provided with a center character, a winning opening, a winning device, etc. (not shown). A glass door 13 is provided on the front side of the game board 12.

  In the present embodiment, a ball launching device 14 that launches a pachinko ball is provided at the lower left portion of the main body frame 11, and the pachinko ball is launched almost vertically upward from the lower left portion of the pachinko machine. A front panel 15 is provided at the lower part on the front side of the main body frame 11, and only one large-capacity ball tray 16 for storing pachinko balls is provided on the front panel 15. A firing operation handle 17 of the ball launching device 14 is provided on the lower right side of the ball tray 16.

  On the other hand, as shown in FIG. 5, on the back surface of the front panel 15 (in front of the ball launching device 14), a ball sending device 18 that feeds pachinko balls in the ball dish 16 to the ball launching device 14 is provided. In this ball delivery device 18, a pachinko ball flowing down from the ball dish 16 is introduced from the ball introduction port 19, and the delivery cam 20 moves up and down around the rotation shaft 21 in synchronization with the launch operation of the ball launch device 14. Then, the introduced pachinko balls are discharged one by one from the ball discharge port 22 and sent to the ball launching device 14.

Next, the configuration of the ball launching device 14 will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the main body substrate 23 of the ball launcher 14 is assembled to the main body frame 11, and a pachinko ball launch pad 24 is fixed to the main body substrate 23 with screws 25. A ball introduction portion 26 for introducing a pachinko ball supplied from the ball delivery device 18 is formed at the center of the launch pad 24, and a supply guide rail 27 having a V-shaped cross section is formed on the left side of the ball introduction portion 26. (See FIG. 3) is fixed with screws 28. The position where the lower part of the pachinko ball is fitted in the gap between the supply guide rail 27 and the receiving part 29 formed below the ball introduction part 26 and the pachinko ball is stationary is the firing position of the pachinko ball. It becomes.

  Further, on the right side of the launch pad 24, a hitting ball rod 30 for firing a pachinko ball is rotatably provided. By hitting the pachinko ball received at the launch position of the launch pad 24 from below with the hit ball portion 31 provided at the lower end of the hit ball 30, the pachinko ball is launched upward through the launch passage 32. .

  On the other hand, as shown in FIG. 3, a rotary solenoid 35 for driving the hitting ball 30 is attached to the back surface of the main body substrate 23. The rotary solenoid 35 has a configuration in which a rotor 37 is disposed on the inner peripheral side of a cylindrical stator 36. The rotating shaft 38 of the rotor 37 is rotatably supported by a bearing 39 fixed to the inner peripheral portion of the stator 36. One end side of the rotation shaft 38 of the rotor 37 protrudes to the front side of the main body substrate 23, and a hitting ball 30 is fastened and fixed to the front end portion with a bolt 40.

  As shown by a solid line in FIG. 2, the position at which the hitting ball 30 rotates downward about the rotation shaft 38 by its own weight or an urging force such as a spring and comes into contact with the lower stopper rubber 41. 30 is the initial position.

  When the firing operation handle 17 is fired, energization / disconnection of the rotary solenoid 35 is repeated at a voltage corresponding to the operation amount. As a result, as shown by a two-dot chain line in FIG. 2, the hitting ball 30 rotates in the firing direction (clockwise direction) from the initial position around the pivot shaft 38 and is received at the launch position of the launch pad 24. After the hit pachinko ball is hit by the hitting ball portion 31, as shown by a solid line in FIG.

  Note that the maximum rotation position of the hitting ball rod 30 in the firing direction is regulated by the stopper piece portion 42 formed integrally with the hitting ball rod 30 coming into contact with the upper stopper rubber 43.

  As shown in FIG. 1, a protective cover 44 made of a transparent resin is provided on the front side of the ball launcher 14. The left end portion of the protective cover 44 is attached to the main body frame 11 via a hinge mechanism 45 so that the protective cover 44 can be opened and closed around a hinge shaft 46 (see FIG. 3) of the hinge mechanism 45. An elastically deformable locking claw 47 (see FIG. 3) is formed at the right end portion of the protective cover 44, and the protective claw 47 is elastically engaged with the engaging portion 48 of the main body frame 11, thereby protecting the protective cover. 44 can be kept closed.

  An opening 49 is formed in the protective cover 44 at a portion corresponding to the sphere introduction portion 26 of the ball launching device 14, and the opening 49 causes the pachinko to be passed from the ball delivery device 18 to the ball introduction portion 26 of the ball launching device 14. A sphere can be introduced. The opening 49 is formed to be slightly larger than the ball introduction portion 26 of the ball launching device 14 so as to avoid interference between the protective cover 44 and the ball delivery device 18. Therefore, in the ball launching device 14, all the parts other than the vicinity of the ball introducing portion 26 are covered with the protective cover 44.

  Further, a launch passage cover portion 51 that covers the lower end portion 32a of the launch passage 32 is integrally formed on the upper portion of the protective cover 44. The launch passage cover portion 51 includes a plurality of ball play protruding toward the launch passage 32 side. A restriction rib 52 (see FIG. 4) is formed to extend along the firing passage 32. The play of the pachinko ball in the lower end 32a of the launch passage 32 is reduced by the ball play restricting rib 52, and a plurality of pachinko balls are accumulated at the lower end 32a of the launch passage 32 (above the launch position) by a foul ball or the like. The pachinko balls are stacked almost in a straight line in the launch direction.

  In the pachinko machine configured as described above, the protective cover 44 is normally closed as shown in FIG. Thereby, since main parts, such as the ball hitting rod 30 of the ball launcher 14, can be covered with the protective cover 44, when the front panel 15 is opened and maintenance work is performed at locations other than the ball launcher 14, It is possible to prevent foreign objects such as tools from accidentally hitting the main parts of the ball launcher 14 and prevent the ball launcher 14 from being damaged.

  Moreover, since the ball launcher 14 of the present embodiment has the hitting ball 30 facing downward, if a pachinko ball or a foreign object enters the ball launcher 14, as shown in FIG. 7, the pachinko ball Or foreign matter may be caught by the refracting portion of the hitting ball rod 30 or may enter the gap between the hitting ball rod 30 and the main body substrate 23, and the hitting ball rod 30 may not be normally fired. In the embodiment, the protective cover 44 can prevent a pachinko ball or foreign matter that has fallen in the vicinity of the ball launcher 14 from entering the ball launcher 14, thereby preventing malfunction of the hitting ball rod 30.

  On the other hand, when performing maintenance work such as cleaning, repair, and inspection of the ball launcher 14, as shown in FIG. 2, if the protective cover 44 is opened forward, the main components of the ball launcher 14 are exposed. Maintenance work of the ball launcher 14 can be performed.

  In the present embodiment, since the firing passage cover portion 51 that covers the lower end portion 32a of the pachinko ball launching passage 32 is integrally formed with the protective cover 44, the firing passage does not fall into the foul bulb passage. Even if it returns to the lower end part 32a of 32, the foul ball can be prevented from jumping out of the firing passage 32, and the foul ball can flow down to the firing position.

  By the way, when the play of the pachinko balls in the launch passage 32 is large, a plurality of pachinko balls accumulated at the lower end portion 32a (above the launch position) of the launch passage 32 by a foul ball or the like are stacked in a zigzag shape. For this reason, even if the lowest pachinko ball (launching pachinko ball) is hit with the striking ball 30, the hitting force is sufficiently applied in the firing direction to the pachinko ball stacked in a zigzag shape above it. The pachinko balls accumulated in the lower end portion 32a of the launch passage 32 cannot be ejected from the launch passage 32 onto the game board surface.

  In this regard, in the present embodiment, the ball play regulation rib 52 is formed in the launch passage cover portion 51 to reduce the play of the pachinko balls in the launch passage 32, so that the lower end 32a of the launch passage 32 is formed by a foul ball or the like. When a plurality of pachinko balls are accumulated (above the firing position), the pachinko balls are stacked almost in a straight line in the firing direction. The pachinko balls accumulated at the lower end portion 32a of the launch passage 32 can be quickly taken out from the launch passage 32.

  Moreover, when adjusting the play of the pachinko ball to the optimum size at the development stage, there is also an advantage that the play of the pachinko ball can be adjusted only by partially correcting the part of the ball play restricting rib 52 of the molding die. is there.

  However, in the present invention, the play of the pachinko ball may be reduced over the entire inner surface of the launch passage cover portion 51 without providing the launch passage cover rib 51 in the launch passage cover portion 51.

  In the above embodiment, only the lower end portion 32 a of the launch passage 32 is covered with the launch passage cover portion 52 of the protective cover 44, but the launch passage cover portion 52 extends upward to cover the upper portion of the launch passage 32. You may do it.

  Alternatively, the firing passage 32 may be covered with a separate component from the protective cover 44 without providing the firing passage cover portion 52 in the protective cover 44.

  Further, in the above embodiment, the protective cover 44 is provided so as to be openable and closable, but the protective cover may be provided so as to be detachable, and even in this case, the intended purpose of the present invention can be sufficiently achieved. .

  In addition, in the present invention, the shape of the protective cover and the parts of the ball launcher covered with the protective cover may be changed as appropriate. Further, the position of the ball launching device is not limited to the lower left part of the pachinko machine, and the ball launching apparatus may be provided in the lower right part of the pachinko machine or the upper part of the pachinko machine.
