To attach the rotary solenoid 31 to the attachment base member 26, attach the attachment piece 37 extending from the main body of the rotary solenoid 31 by penetrating the rotary solenoid 31 from the front side of the attachment base member 26 into the drive source fitting hole 35. It suffices 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. The rotary solenoid 31
The mounting to the mounting base 26 is not limited to the front side of the mounting base 26, and the mounting base 26 may be mounted from the back side by forming a through hole for the output shaft.

The launch rail 33 is a rail for guiding the ball hit by the launching pestle 32 toward the ball hitting guide path of the game board 8, and a predetermined angle (front frame) on the upper left side of the mounting base member 26. When installed, the upper end of the slope is the ball hitting guide channel
6 is obliquely provided at an inclination angle slightly upward of the lower end entrance. In the embodiment shown in the drawings, the mounting base member 26 is made of synthetic resin, so that the rail base portion 38 is formed.
Is integrally formed with the mounting base member 26, a shallow V-shaped groove 39 is formed on the upper surface, and a fastening piece 40 is formed downward from the upper end of the front V-shaped groove 39. By covering the rail base portion 38 with the member material 41, the fastening piece 4
The rail base portion 38 is fastened to the rail base 38 by passing a screw through the fastening hole 0.

When the mounting base member 26 and the rail base portion 38 are integrally molded in this manner, the position of the firing rail 33 with respect to the mounting base member 26 is always constant, position adjustment work becomes unnecessary, and the assembling work is rationalized. You can

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 '
When is attached to the surface of the mounting base member 26 with a screw or the like, the lower surface of the rail upper surface member member 41 can be reliably brought into contact with the upper surface of the rail base portion 38. Therefore, the positional relationship between the V-shaped groove 39, which is the ball striking surface, and the mounting base member 26 can be further stabilized, and thereby the accuracy can be further enhanced.

Further, the inclined lower end of the launch rail 33 is the hitting ball launching position 19 when the ball is launched, and it is necessary to stop the ball supplied from the ball feeding device 20 at this hitting ball launching position 19. Therefore, in the present embodiment, the ball stopping member 42 is provided above the inclined lower end of the launch rail 33 with a space allowing the resilient portion 34 of the launching pestle 32 to enter from the surface of the mounting base member 26. It is projected integrally with 26. In this way, if the ball stopping member 42 is integrally molded with the mounting base member 26, it is not necessary to align the firing rail 33 and the ball stopping member 42.
It is possible to rationalize the assembly. Also, launch rail 3
If the positional relationship between 3 and the ball stopping member 42 is always constant,
Which firing unit 1 is the sphere supplied on the firing rail 33
Even if it is 4, it will always stop at a fixed position, so it is possible to eliminate individual differences in the firing unit 14,
As a result, the work of adjusting the firing pestle 32 is greatly reduced.

Although the ball stopping member 42 is integrally formed with the mounting base member 26 in this embodiment, the present invention is not limited to this, and a member formed separately from the mounting base member 26 is used as a fixing means such as a screw. May be fixed by.

Further, a first stopper 43 and a second stopper 44 for restricting the rotation range of the launching punch 32 are attached to the attachment base member 26. As shown in FIG. 3, the first stopper 43 causes the launching pestle 32 to stand by at a launch preparation position, which is separated rearward from the hitting launch position 19, and in this embodiment, a cylindrical rubber block is attached to the mounting base member 26. It is fixed with screws on the surface of. On the other hand, in the second stopper 44, the launching pestle 32 that has bounced off the ball at the hitting ball launching position 19 has the launch rail 33
The stopper 44 is a stopper for preventing contact with the rubber block in the holder 44 'having a long hole, and the firing punch 32 is brought into contact with the rubber block to regulate the forward movement position.

Then, by loosening the screw passed through the elongated hole of the holder 44 ', the front-back position can be adjusted, and the stop position of the firing punch 32 can be finely adjusted by this position adjustment. In this embodiment, since the position of the launch rail 33 and the position of the ball stop member 42 are preset positions,
Similarly to the first stopper 43, the second stopper 44 can also be of a fixed type, which makes adjustment work unnecessary and improves work efficiency.

The firing unit 14 having the above-mentioned structure
Can be combined and stored as a unit in advance, and what is stored in the pachinko machine 1 assembly process may be assembled. Then, when the firing unit 14 is assembled, in this embodiment, the rail base 38 and the ball stopping member 42 are integrally molded on the mounting base member 26.
The position adjustment work of the firing rail 33 and the ball stopping member 42 with respect to the mounting base member 26 is unnecessary. Further, since the mounting position of the rotary solenoid 31 is also set in advance, in the assembling process of the firing unit 14, the firing punch 3
It suffices to confirm the positional relationship between the tip of the second bullet firing portion 34 and the hitting ball firing position 19. Incidentally, in order to adjust the position due to the warp of the launching pestle 32 and the position error of the resilient part 34, the mounting hole of the rotary solenoid 31 may be made slightly larger or may be made a long hole for fine adjustment. Good. Further, since the firing unit 14 includes the firing rail 33, it is possible to adjust and confirm the resilience operation of the firing pestle 32 by performing a trial hit in advance before assembling the front rail 5.

The firing unit 14 assembled in this way
In order to assemble the front panel 5 of the pachinko machine 1, with the open / close panel 3 open, as shown in FIG. 5, the rear side of the firing unit 14 is placed on the standing 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 recessed in the standing surface 13.
By fitting the positioning projection 36 into the positioning hole 45 of the recess 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 and the mounting base member 26 is fixed in the recess 27 by tightening.

In this embodiment, the recess 2 formed on the upright surface 13
Since the shape and size of No. 7 are formed so as to correspond to the shape and size of the mounting base member 26, the positional relationship between the positioning protrusion 36 projecting on the back surface of the mounting base member 26 and the positioning hole 45 of the recess 27. Is not visible from the front,
If the outer peripheral edge of the mounting base member 26 is fitted so as to fit within the opening edge of the recess 27, the positions of the positioning protrusion 36 and the positioning hole 45 naturally coincide with each other. Therefore, the mounting base member 26 can be easily attached to a predetermined position even when it cannot be seen from the front side. That is, in this embodiment, the upper, lower, left, and right opening edges of the recess 27 regulate the left, right, upper, and lower positions of the mounting base member 26. In other words, the left, right, upper, and lower positions of the mounting base member 26 are regulated. If the mounting base member 26 is provided with a member such as a convex portion, the mounting base member 26 can be easily fitted to a predetermined position.

When the firing unit 14 is attached to the front frame 5 side of the pachinko machine 1 in this manner, it can be attached only from the front side of the front frame 5, so that the hand can be turned to the back side of the front frame 5, Alternatively, since it is not necessary to reverse the front frame 5, the work is easy. If a trouble should occur, 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 the repair is easy. When the opening / closing panel 3 is opened, the launching punch 32 and the launching rail 33 can be easily reached, and daily maintenance work such as cleaning the rails is also easy.

Further, the thickness of the mounting base member 26 and the recess 2
Since the depth of 7 is set to the same dimension, when the mounting base member 26 is fitted into the recess 27, the upright surface 13 and the surface of the mounting base member 26 are flush with each other, and the V-shaped firing rail 33 is formed. The center line of the groove 39 and the center line of the hitting ball guide path of the game board 8 coincide.

When the firing unit 14 is attached to the unit support portion of the front frame 5, the entrance of the hitting ball guide flow passage 16 of the game board 8 is located ahead of the upper end of the inclination of the firing rail 33, so that the rotary solenoid is provided. When the launching punch 32 is rotated by the drive of 31 to repel the ball at the hitting ball launching position 19, the hitting ball is V-shaped guide groove 39 on the upper surface of the launching rail 33.
After running, the ball passes through the hitting ball guide channel 16 of the game board 8 and jumps into the upper part of the game area 9, and then hits an obstacle nail and flows down while changing the flow direction, and wins one of the prize tools. Becomes a safe ball, or flows down without winning any of the winning tools and enters an out opening opened at the bottom of the game area 9 to become an out ball.

Further, although the shot ball that has been shot does not reach the game area 9, or even if it reaches the game area 9 once, the ball that bounces back and goes backwards through the ball guide passage 16 becomes a foul ball. These foul balls are overflow gutters 18
It enters the foul ball recovery port 47 which is opened in the middle of the opening between the slanted lower end of the outer guide rail 15a and the slanted upper end of the launch rail 33, and is discharged to the lower tray 11 via the overflow gutter 18.

The unit supporting portion in the above-mentioned embodiment is constituted by forming the recess 27 in the standing surface 13 standing upright under the game board 8, but the unit supporting portion in the present invention supports the firing unit 14. Any configuration may be used as long as it has a function. For example, the erected surface 13 without the recess 27 may be used, or a crosspiece, an arm, or a support column may be used.

Further, the positioning member for specifying the positions of the firing unit 14 and the unit supporting portion are the positioning projection 36 projecting from the mounting base member 26 shown in the above embodiment and the bottom surface 27 'of the recess 27 of the upright surface 13. It is not limited to the positioning hole 45 opened in the above. For example, a positioning hole may be formed in the mounting base member 26, and a positioning projection 36 that fits into the positioning hole may be 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.

Further, the drive source of the firing unit 14 is not limited to the rotary solenoid 31 and 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 launching pestle 32 is not limited to the rotary type as in the above-described embodiment, but may be a linear movement type that moves the rod-shaped launching pestle 32 in the axial direction.

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

Although the above embodiment is a pachinko machine 1 which shoots a thrown ball to play a game, the present invention is not limited to this, and any game machine which shoots a ball to play a game can be used. It may be a game machine. For example, an enclosed ball-type pachinko machine that circulates the balls that are enclosed inside, an arrangement ball-type game machine,
It may be a ball game machine such as a sparrow ball game machine.

Therefore, even if the drive source projects to the back surface of the mounting base member, the drive source does not interfere with the upright surface, and the mounting base member reliably contacts the bottom surface of the recess. Therefore, the firing unit can be securely attached in a more stable state. Further, when the drive source is penetrated into the drive source accommodation hole, the periphery of the drive source is attached in an open state, so that the heat generated by the drive source is easily released into the atmosphere, and the heat dissipation effect is excellent.

According to the seventh aspect of the present invention, since the rail base is integrally molded when the mounting base member is molded with the synthetic resin, the position of the rail base with respect to the mounting base member is always molded at the same position. Therefore, if the rail base is covered with the metal rail upper surface member to form the launch rail, the position of the launch rail with respect to the mounting base member is always the same. Therefore, it is not necessary to adjust the position of the launch rail.

According to the eighth aspect of the present invention, since the drive source is fixed to the mounting base member made of metal, the heat generated from the driving source is transmitted to the mounting base member, and the mounting base member also functions as a heat sink. It can radiate heat from the surface to the atmosphere. Therefore, heating of the drive source can be reliably prevented.
