On the other hand, while the striking mallet 18 is being driven by the cam body 23 of the firing motor 20, the permanent magnet of the operating member 25 of this striking mallet 18 is driven.
As shown by the phantom lines in FIG. 2, 29,67 are separated from the ball feeding member 33, and repulsive force is not generated between the permanent magnets 29,67. Support shaft
It is in the return position where it rotates about 32 times and comes into contact with the first stopper 70. That is, the ball receiving portion 59 of the ball feeding member 33 is the ball holding portion.
It corresponds to the lower side of 37. Therefore, the sphere holder 37
The game ball B inside is fitted in the ball receiving portion 59 and is supported from below.

From this state, when the hammer 18 is rotated in the direction of the arrow e, the permanent magnets 29,67 on the operating member 25 side approach the permanent magnets 29,67 on the driven member 57 side, as shown in FIG. Therefore, a repulsive force is generated between the permanent magnets 29 and 67, and the hammer 18
The ball feed member 33 is connected to the support shaft 32 in conjunction with the rotation of the e in the arrow direction.
Rotate around in the direction of arrow b. At this time, the game ball B fitted in the ball receiving portion 59 of the ball feeding member 33 is fed from the ball holding portion 37 to the ball guiding portion 52 side by the rotation of the ball feeding member 33 in the ball feeding case 31. Go.

Then, the hammer 18 is rotated to the striking position, the permanent magnets 29,67 of the actuating member 25 reach the straight line connecting the fixed shaft 8 and the support shaft 32, and the permanent magnets 29,67 The repulsive force causes the ball feeding member 33 to come into contact with the second stopper 71. Therefore, the game ball at the launch position A of the launch rail 14
At the same time as hitting B, the ball receiving portion 59 of the ball feeding member 33 corresponds to the ball guiding portion 52 as shown in FIG. 3, and the game ball B of the ball receiving portion 59 moves backward along the inclination of the receiving surface. It rolls and falls to the side of the ball guide 52, and the game ball B is dropped from the ball guide 52 through the ball outlet 51 onto the launch rail 14. Therefore, the next game ball B can be fed onto the launch rail 14 after the game ball B has been launched.

On the other hand, if the ball feeding member 33 is in the rotating position,
As shown in FIG. 3, the ball support part 58 of the ball feed member 33 corresponds to the lower side of the ball holding part 37, and after sending the game ball B fitted in the ball receiving part 59, from the ball entrance 36 to the ball holding part.

Further, the repulsive force of the two permanent magnets 29, 67 is utilized to interlock with the rotation of the striking mallet 18 in the firing direction to move the ball feeding member 33 to the rotation position where it abuts against the second stopper 71. Since the is being rotated, the striking mallet 18 side has rotated too much at this time,
It is only necessary that the different poles of the two permanent magnets 29, 67 correspond to each other so that an attractive force is generated, and therefore it is not necessary to exactly match the rotational strokes of the hammer 18 and the ball feed member 33. .

After the striking mallet 18 has launched the game ball B at the launch position A of the launch rail 14, the cam body 23 on the launch motor 20 side again contacts the cam roller 22 and starts driving the striking mallet 18, 18 rotates rapidly around the fixed shaft 8 in the direction of arrow c against the spring 19. Therefore, the permanent magnet on the operating member 25 side
Since 29,67 are suddenly separated from the permanent magnets 29,67 on the driven member 57 side of the ball feeding member 33 in the rotating position, both permanent magnets 2
The repulsive force is not generated between 9,67, and the ball feeding member 33 returns to the return position by the gravity of the weight 65 as shown in FIG.
