In the pachinko machine having the above structure, when playing a pachinko game, after putting the game ball B on the upper plate 10, the operation handle 35 is operated to set the game ball B to 1 by the launching device 9.
Fire one by one along the guide rail 11 to the upper side of the game board 7.

At this time, the fixing means 19 is in a state where the operation handle 35 is released from being fixed. That is, the operating body of the fixing means 19
51 is pushed back by the return spring 55 and is in a state of protruding from the front surface of the palm rest 34 as shown by the solid line in FIG.
Therefore, the pressing body 49 is pulled back by the operating body 51 via the engaging portions 65 and 66 of both, and is in a state of being separated from the disc portion 41 of the operating handle 35. At this time, the pressing spring 50 is almost free. Therefore, the operation handle 35 can be freely rotated around the handle shaft 33.

Therefore, when the operation handle 35 is rotated about the handle shaft 33, the gear 37 rotates about the shaft portion via the handle shaft 33 and the gear 36, and therefore, it is proportional to the operation amount of the operation handle 35. As a result, the spring pressure of the tension spring 17 changes. For example, when the operation handle 35 is operated in the direction of arrow a in the figure,
Since the gear 37 rotates in the direction of the arrow b, the tension spring 17 is pulled and the spring pressure is increased.

On the other hand, at this time, the player touches the palm rest 34 with the palm and operates the operation handle 35, and the finger contacts the touch piece 47 of the touch switch, so that the operation handle 35 is rotated. Then, the firing motor 24 is actuated, the cam body 28 fixed to the rotary shaft 27 thereof rotates in the direction of arrow c, the cam body 28 contacts the cam roller 30, and the striking mallet 16 resists the tension spring 17. Rotate around the support shaft 21 in the direction of arrow d. And the cam body 28
When the hammer comes off the cam roller 30, the hammer 16 moves the tension spring 17
It is pulled back around the spindle 21 in the firing direction (the direction opposite to the arrow d), and hits the game ball B on the launch rail 15 with a hitting force corresponding to the spring pressure of the tension spring 17 at that time, and the game ball B is hit. Fire it on the guide rail 11 side.

Since the individual pachinko machines have different flight characteristics, drop characteristics, etc. of the game ball B for each individual, at the beginning of the game, the player appropriately operates the operation handle 35 about the handle shaft 33. Adjust the spring pressure of the tension spring 17 to confirm the flight state of the game ball B after launch and the position where the game ball B falls.
Then, when the game ball B comes to fly to the optimum position, thereafter, the fixing handle 19 fixes the operation handle 35 at that position.

At this time, with the position of the operating handle 35 being fixed, the operating body 51 is pushed in with the thumb or palm in the direction of arrow e in FIG. Then, the pressing body 49 is pressed through the pressing spring 50, and the disc portion 41 of the operation handle 35 is pressed against the pressing body 49 and the receiving plate.
It is clamped between 48 and the operating force is 35 due to the frictional force.
Is fixed.

At this time, the operating body 51 is locked by the lock mechanism 58 at the pushing position. That is, when the operating body 51 is pushed in, the locking pin 62 of the lock mechanism 58 moves in the direction of arrow f in FIG. 5 along the outward path side of the circulation groove 61. Then, when the pushing force is released, the locking pin 62 is locked by the locking portion 59, so that the operating body 51 is locked at the pressing position.

Therefore, since the operation handle 35 can be easily and surely fixed by the fixing means 19 at an arbitrary operation position, that is, an arbitrary spring pressure position, the player thereafter touches the touch piece.
All you have to do is put your hand on the palm rest 34 so that your fingers do not separate from 47.

At the end of the game or when the spring pressure of the tension spring 17 is readjusted, the operation handle 35 can be released by pushing the operation body 51 in the direction of arrow e in FIG. That is, when the operating body 51 is pushed again, the locking pin 62 disengages from the locking portion 59 and moves to the return path side of the circulation groove 61, so if the pushing of the operating body 51 is released after that, the return spring 55 operates it. The body 51 is pushed back to the protruding position. Therefore, the pressing body 49 is separated from the disc portion 41 of the operation handle 35,
The fixing of the operation handle 35 by the fixing means 19 is completely released, and the operation handle 35 becomes rotatable around the handle shaft 33.

When the player's finger is separated from the touch piece 47 while the operation handle 35 is being fixed by the fixing means 19, the firing motor
Although 24 stops and the shooting operation of the game ball B stops, when the touch piece 47 is swung again, the game ball B can be shot under the condition before the stop.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, even in a type in which the hammer 16 is fixed to the tip of the movable iron core of the solenoid, and the striking force is adjusted by controlling the solenoid current by the operating means 18, the solenoid current is fixed by the fixing means 19. If configured, it can be implemented in the same manner.

The operating means 18 may be provided by rotating the operating handle 35, or may be provided with a motor for rotating the gear forward and backward, and the spring pressure may be adjusted by controlling the motor by a switch operation. Further, the driving means 23 may be configured such that the striking mallet 16 is driven by a solenoid without using the firing motor 24.

It is sufficient that the fixing means 19 can be fixed with an arbitrary spring pressure so that the spring pressure of the tension spring 17 does not change,
Where the operation means 18 is fixed is free. For example,
The fixing means 19 may be provided so as to grasp and fix the handle shaft 33.

However, in the current launching device 9, the fixing means 19 is incorporated into the inside of the handle support 32 and the palm rest 34, particularly in the palm rest 34 as in the embodiment, and the operating body 51 is moved to the front side. If it is configured to be operated from, it can be easily implemented.
Further, in the embodiment, the pachinko machine has been exemplified, but the same can be applied to an arrangement ball machine and various other ball game machines.
