etc. are provided. When this game board 6 is fixed from the back with the game section 40 facing the window 5 of the front frame 3, the starting position 22 of the guide rail 21 is connected to the ball feeding device 23 through the outlet 39 of the case 20. facing the ball feeding section 31. In addition, game board 6
The lower part 42 of the back surface of the front frame 3 constituted by the surface of the front frame 3 and the case 20 is provided with the ball launcher 1
1 will be provided. The ball launcher 11 is located at a launch position 22
The ball is fired into the gaming section 40, and as shown in FIG.
The drive section 44 is electrically connected to the batted ball firing operation section 10.

The firing punch 35 has its base end connected to the base plate 43 by a support shaft 45.
It is rotatably mounted on a bearing part 46 of the ball, and a springing part 47 is provided at the upper free end to project the ball into the firing position 22, and a springing part 47 is provided in the middle of the length in a substantially horizontal direction. Connect one end of spring 48.

Further, the spindle 45 of the firing punch 35 is provided with a stay 49 that rotates integrally with the firing punch 35, and a roller 50 is horizontally pivoted on the upper portion of the stay 49.

The drive unit 44 includes a drive source (for example, a motor equipped with a speed reducer) 52 on the frame 51 of the board 43,
A cam 54 is provided on the output shaft 53 of the drive source 52, and the rotating cam presses the roller 50 to tilt the firing punch 35 backward from the firing position 22.

The batted ball firing operation unit 10 includes an operation dial 55 and a take-up pulley 5 provided on a shaft 56 of the operation dial 55.
7, and one end of a wire rod 58 is wound and fixed around the winding pulley 57. The wire 58 changes its direction by pulleys 59, 59 pivoted on the back surface of the front frame 3, and is connected to one end of the spring 48 via an adjustment rod 60. Further, a start switch 61 is provided facing the winding pulley 57, and the start switch 61 is electrically connected to the drive source 52.

Therefore, when the player rotates the operating handle 55, the take-up pulley 57 rotates, the protrusion 62 provided on the pulley 57 disengages from the start switch 61, turns on the switch 61, and the wire rod Wind up 58. When the wire 58 is wound, the spring 48 is expanded and the desired bias is applied to the firing punch 35. Further, when the start switch 61 is turned on, the cam 54 of the drive source 52 rotates, and the cam 54 rotates.
presses the roller 50 and moves the firing punch 35 to the firing position 2.
2. Tilt backwards. The firing punch 35 is linked with a pressing rod 36 that tilts integrally with the firing punch 35. In the embodiment shown in the drawings, the pressing rod 36 is shown as a rod-like member extending from a base end fixed midway along the length of the firing rod 35, with the tip thereof bent into a hook shape. However, the pressing rod 36 may be in the form of a shaft that projects directly laterally from the side surface of the firing punch 35, or the pressing rod 36 may be extended from the support shaft 45 of the firing punch 35. good. In addition, the pressing rod 36
An operating cam 37 is pivotally supported on the upper mounting plate 63, and a cam piece 37'' of the operating cam 37 is attached to the pressing rod 3.
It is located within the rotation range of the upper end hook portion 36' of 6.
Therefore, when the pressing rod 36 rotates due to the tilting of the firing punch 35, the hook portion 36' presses the cam piece 37'' and rotates the operating cam 37.The hook portion 3 of the pressing rod 36
The contact start point P ₀ where the cam 6' contacts the operating cam 37 and starts pressing is as shown in FIGS. 7 and 8.
The shaft 37' of the operating cam 37 and the support shaft 45 of the firing punch 35
It is located behind the firing position 22 from the straight line connecting the two.

Furthermore, as is clear from FIG. 8, the contact starting point P ₀
A gap is formed between the rotation start position of the pressing rod 36 (the position indicated by a solid line in the figure). That is,
The pressing rod 36 starts to tilt integrally with the firing punch 35, but there is a slight time lag until the hook 36' of the pressing rod 36 reaches the contact starting point _P0 , ₀ is located at a point later than the start of tilting of the firing punch 35.

Therefore, when the pressing rod 36 starts to tilt integrally with the firing punch 35, the pressing rod 36 does not act on the operating cam 37, but when the firing punch 35 is further tilted, the hook portion 36' moves into the cam piece 37''. Rotate the cam piece 37'' while moving the side part from top to bottom,
A pressing rod 36 acts on an actuating cam 37.

Note that the load applied to the pressing rod 36 is
As the actuating cam 37'' rotates, the contact point P between the hook portion 36' and the actuating cam 37 becomes closer to the shaft 3 of the actuating cam 37.
As it moves away from 7', it is gradually reduced. Therefore, the load on the drive source 52 is at its minimum from the start of the tilting of the firing punch 35 until the hook portion 36' reaches the abutment starting point _P0 , and when the pusher rod 36 and the operating cam 37 make contact with each other. The load at the starting point P ₀ is maximum,
Thereafter, as the actuating cam 37 rotates, it is reduced.

In addition, as shown in FIG. 9, the contact starting point P ₀ is
The shaft 37' of the operating cam 37 and the support shaft 45 of the firing punch 35
If the position is located forward of the straight line connecting the two, that is, closer to the firing position 22, the portion where the trajectory a of the hook portion 36' and the trajectory b of the contact start point _P0 of the actuating cam 37'' overlap (in the figure) , the shaded area), the hook 36' abnormally presses the side of the cam piece 37'', and while the hook 36' moves within the shaded area, the load on the drive source 52 is reduced. It may increase or decrease.

However, as in the present invention, if the contact start point P ₀ is located behind the straight line connecting the shaft 37' and the support shaft 45, the contact start point between the locus b of the hook portion 36' and the actuating cam 37'' The locus b of P ₀ does not overlap.Therefore, the operating cam 37 operates smoothly.

When the firing punch 35 is tilted to its maximum angle as shown by the chain line in FIG.
8 is inclined to raise the rear end of the ball feeding section 31.
When the rear end of the ball feeding section 31 rises, the ball mounting section 3 at the front end
1' is lowered, and the balls that had been stopped near the lower end of the slope of the supply number control gutter 30 are placed on the ball mounting portion 31'. Then, when the cam 54 of the drive unit 44 is disengaged from the roller 50, the firing punch 35 returns and rotates vigorously due to the bias of the spring 48, and fires the ball at the firing position 22. When the firing punch 35 returns and rotates, the pressing rod 36 separates from the operating cam 37, so that the operating cam 37 and the operating lever 38 become freely rotatable. When the operating lever 37 becomes freely rotatable, the ball feeding section 31 swings by the weight 64 to raise the ball on the ball mounting section 31'. The ball is
When the ball rises, it falls from the outlet 39 of the case 20 onto the guide rail 21 due to the slope of the upper surface of the ball mounting portion 31', and stops at the firing position 22.

The firing punch 35 repeats the above tilting movement to the firing position 2.
At the same time as firing two balls, the ball supply device 23 is operated to supply one ball to the firing position 22.

As explained above, according to the present invention, the contact point between the pressing rod and the operating cam gradually moves and the two do not interfere with each other, so that the load on the pressing rod does not increase midway. This prevents damage to the pressing rod and unnecessary load on the drive source.

As a result, the rotation of the actuating lever becomes smooth, and the swinging movement of the swinging ball feeder becomes stable, allowing the ball to be regularly and smoothly fed to the firing position, and the ball sits well at the shooting position. This eliminates uneven skipping.
