As No. 4, a coil spring or urethane rubber is attached.

The embodiment of the mounting base member 26 shown in the drawing is a plate made of synthetic resin molded into a shape, size and thickness that can be fitted into the recess 27 of the upright surface 13 described above. A drive source fitting hole 35 penetrating through the solenoid 31 is positioned at a predetermined position (in the present embodiment, a lower right portion in the drawing).
And a positioning protrusion 3 as a positioning member for specifying the positions of the firing unit 14 and the unit support on the back surface.
6 are provided at predetermined positions by integral molding. In order to mount the rotary solenoid 31 on the mounting base member 26, the rotary solenoid 31 is penetrated from the front side of the mounting base member 26 into the drive source fitting hole 35 and a mounting piece 37 extending from the main body of the rotary solenoid 31 is mounted. What is necessary is just to contact the surface of the base member 26, pass a screw through the mounting hole of the mounting piece 37, and tighten the screw into the mounting hole of the mounting base member 26. In addition, the rotary solenoid 3
The mounting of the first mounting base 26 is not limited to the front side of the mounting base 26, and the mounting base 26 may be provided with a through hole for the output shaft and mounted from the rear side.

The firing rail 33 is a rail for guiding the hit ball hit by the firing punch 32 toward the hitting guide flow path of the game board 8, and is provided at a predetermined angle (front surface) on the upper left side of the mounting base member 26. When the frame is mounted, the inclined upper end is provided obliquely at an inclination angle slightly upward of the lower end entrance of the hitting ball guide channel 16). In the embodiment shown in the drawings, since the mounting base member 26 is formed of synthetic resin, the rail base 38 is formed integrally with the mounting base member 26,
A shallow V-shaped groove 39 is formed on the upper surface, and the front V-shaped groove 3 is formed.
A metal plate upper surface member 41 having a fastening piece 40 formed downward from the upper end of 9 is placed on the rail base 38 and fastened to the rail base 38 through a screw in a fastening hole of the fastening piece 40. is there.

As described above, when the mounting base member 26 and the rail base 38 are integrally formed, the position of the firing rail 33 with respect to the mounting base member 26 is always constant, so that the position adjusting operation becomes unnecessary and the assembling operation is rationalized. Can be.

As shown in FIG. 5, a second fastening piece 40 'is formed upward from the upper end of the V-shaped groove 39 of the rail upper surface member 41 on the mounting base member side, and the second fastening piece 40' is formed. Piece 40 '
Is fixed to the surface of the mounting base member 26 with screws or the like, so that the lower surface of the rail upper surface member 41 can reliably contact the upper surface of the rail base 38. Therefore, the positional relationship between the V-shaped groove 39, which is the hit ball running surface, and the mounting base member 26 can be further stabilized, and the accuracy can be further improved.

Further, the inclined lower end of the shooting rail 33 is a hitting ball firing position 19 when shooting a ball, and it is necessary to stop the ball supplied from the ball feeding device 20 at the hitting ball firing position 19. Therefore, in the present embodiment, the ball stopping member 42 is provided above the inclined lower end of the firing rail 33 at an interval at which the resilient portion 34 of the firing punch 32 can enter, from the surface of the mounting base member 26 to the mounting base member 26. 26 and are integrally formed. In this manner, when the ball stopping member 42 is integrally formed with the mounting base member 26, there is no need to align the firing rail 33 and the ball stopping member 42, so that the assembly can be rationalized. Further, if the positional relationship between the firing rail 33 and the ball stopping member 42 is always constant, the ball supplied on the firing rail 33 will always stop at a fixed position regardless of which firing unit 14 is used. In addition, the individual difference of the firing unit 14 can be eliminated, and the adjustment work of the firing punch 32 can be greatly reduced.

In this embodiment, the ball stopping member 42 is formed integrally with the mounting base member 26. However, the present invention is not limited to this. The ball stopping member 42 may be formed separately from the mounting base member 26 by fixing means such as screws. May be fixed.

A first stopper 43 and a second stopper 44 for restricting the rotation range of the firing punch 32 are attached to the attachment base member 26. As shown in FIG. 3, the first stopper 43 causes the firing punch 32 to stand by at a firing preparation position separated from the hit ball firing position 19 rearward. In the present embodiment, the cylindrical rubber mass is attached to the mounting base member 26. It is fixed on the surface with screws. On the other hand, the second stopper 44 is configured such that the launching punch 32 that has launched the ball at the hit ball launching position 19 is
3 is a stopper for preventing a collision with the rubber block 3. The rubber block is provided in a holder 44 'having a long hole, and the firing punch 32 is brought into contact with the rubber block to regulate the advance position.

When the screw passing through the long hole of the holder 44 'is loosened, the front / rear position can be adjusted, and the stop position of the firing punch 32 can be finely adjusted by this position adjustment. In the present embodiment, since the position of the firing rail 33 and the position of the ball stop member 42 are preset positions, the second stopper 44 can be fixed in the same manner as the first stopper 43. No adjustment work is required, and work efficiency can be improved.

The firing unit 14 having the above configuration
Can be combined and stored as a unit in advance, and what has been stored in the assembling process of the pachinko machine 1 may be assembled. In assembling the firing unit 14, in this embodiment, since the rail base 38 and the ball stopping member 42 are integrally formed on the mounting base member 26, the positions of the firing rail 33 and the ball stopping member 42 with respect to the mounting base member 26. No adjustment work is required. In addition, since the mounting position of the rotary solenoid 31 is also set in advance, in the assembling process of the firing unit 14, it is sufficient to confirm the positional relationship between the tip of the resilient portion 34 of the firing punch 32 and the hit ball firing position 19. It is. In order to adjust the position due to the warp of the launching punch 32 or the position error of the resilient portion 34, the mounting hole of the rotary solenoid 31 may be formed to be slightly larger or elongated to allow fine adjustment. Good. Further, since the firing unit 14 includes the firing rail 33, it is possible to adjust and confirm the elasticity of the firing punch 32 by performing trial hitting before assembling to the front frame 5.

The firing unit 14 assembled in this manner
In order to assemble into the front frame 5 of the pachinko machine 1, with the opening and closing panel 3 opened, as shown in FIG. 5, the rear side of the firing unit 14 is attached to the upright surface 13 of the front frame 5 from the front of the pachinko machine 1. In this state, the firing unit 14 is retracted, the rotary solenoid 31 is inserted into the drive source housing hole 28, and the mounting base member 26 is inserted into the recess 27 of the upright surface 13.
By fitting the positioning projection 36 into the positioning hole 45 of the concave portion 27, the position of the firing unit 14 is adjusted to a predetermined position. Then, the mounting base member 26
A screw is inserted into the mounting hole 46 from the surface side of the mounting hole 46 and tightened to fix the mounting base member 26 in the concave portion 27.

In this embodiment, since the shape and size of the concave portion 27 formed in the upright surface 13 are formed in accordance with the shape and size of the mounting base member 26, the recess 27 is protruded from the rear surface of the mounting base member 26. Positioning protrusion 36 and recess 27
Even if the positional relationship with the positioning hole 45 is not visible from the front, if the fitting is performed so that the outer peripheral edge of the mounting base member 26 fits within the opening edge of the concave portion 27, the position of the positioning projection 36 and the positioning hole 45 is adjusted. Matches naturally. Therefore,
Even if the mounting base member 26 cannot be seen from the front side,
Can be easily attached to a predetermined position. That is,
In the present embodiment, the upper, lower, left, and right edges of the recess 27 regulate the left, right, up, and down positions of the mounting base member 26. If a member such as a part is provided, the mounting base member 26 can be easily adjusted to a predetermined position.

When the firing unit 14 is mounted on the front frame 5 side of the pachinko machine 1 in this manner, the firing unit 14 can be mounted by working only from the front of the front frame 5. Alternatively, since there is no need to invert the front frame 5, the operation is easy. In the event that a trouble occurs, the firing unit 14 can be removed from the front side of the pachinko machine 1 simply by opening the open / close panel 3 and loosening the screw, so that repair is easy. When the opening / closing panel 3 is opened, the firing punch 32 and the firing rail 33 are easily accessible, so that daily maintenance work such as cleaning of the rail is also easy.

The thickness of the mounting base member 26 and the recess 2
7 are set to the same size, when the mounting base member 26 is fitted into the concave portion 27, the upright surface 13 and the surface of the mounting base member 26 become flush, and the V-shaped The center line of the groove 39 coincides with the center line of the hitting guide path of the game board 8.

When the firing unit 14 is attached to the unit supporting portion of the front frame 5, the entrance of the hitting guide flow path 16 of the game board 8 is located ahead of the inclined upper end of the firing rail 33. When the launching punch 32 is rotated by the driving of the ball 31 and the ball at the hitting ball firing position 19 is hit, this hitting ball is V-shaped guide groove 39 on the upper surface of the firing rail 33.
And then jumps into the upper part of the game area 9 through the inside of the ball guide path 16 of the game board 8, thereafter hits an obstacle nail, flows down while changing the flow direction, and wins one of the winning tools. The ball flows down without making a prize, or flows into the out-opening opening at the bottom of the game area 9 and becomes an out-ball.

Further, although the shot ball which has been shot does not reach the game area 9 or once hits the game area 9, the ball which rebounds and goes back through the hitting guide channel 16 becomes a foul ball. These foul spheres are filled with overflow gutter 18
, Which is opened between the lower end of the outer guide rail 15 a and the upper end of the firing rail 33, and is discharged to the lower plate 11 via the overflow gutter 18.

The unit support in the above-described embodiment is formed by forming the recess 27 in the upright surface 13 erected below the game board 8, but the unit support in the present invention supports the firing unit 14. Any configuration may be used as long as it has a function. For example, it may be a simple upright surface 13 having no recess 27 formed thereon, or may be a crosspiece, an arm, or a support pillar.

The positioning member for specifying the position of the firing unit 14 and the unit support portion includes a positioning projection 36 projecting from the mounting base member 26 shown in the above-described embodiment and a bottom surface 27 ′ of the concave portion 27 of the upright surface 13. However, the present invention is not limited to the positioning hole 45 opened in the first embodiment. For example, a positioning hole may be formed in the mounting base member 26, and a positioning protrusion 36 fitted into the positioning hole may be protrudingly provided on the upright surface 13 side (unit support portion side). The outer peripheral surface of the mounting base member 26 may be used as a positioning member.

The driving source of the firing unit 14 is not limited to the rotary solenoid 31, but may have any configuration as long as it has a function of driving the firing punch 32. For example, a plunger solenoid may be used. Also,
The firing punch 32 is not limited to the rotary type as in the above embodiment, but may be a linear motion type in which the rod-shaped firing punch 32 is moved in the axial direction.

The mounting base member 26 is not limited to a synthetic resin. For example, the mounting base member 26 may be formed of a metal plate having good heat conductivity, and may function as a heat sink for radiating heat generated from a driving source such as the rotary solenoid 31. In this case, it is desirable to form a radiation fin on the mounting base member 26.

The above-described embodiment is a pachinko machine 1 that shoots a thrown ball to play a game. However, the present invention is not limited to this, and any game machine that shoots a ball to play a game. A gaming machine may be used. For example, it may be a ball-and-ball game machine such as an enclosed-ball-type pachinko machine, an arranged-ball-type game machine, and a sparrow-ball-type game machine that circulates balls enclosed therein.
