4 is pivoted downward (in the position indicated by the solid line in FIG. 10), so that
The ball supply member 58 is pivoted downward (clockwise) through the ball 1, and the ball received at the head of the ball passage 67 is received and held by the ball receiving portion 69 by the upward rotation of the ball supply member 58. When the ball supply member 58 is rotated downward, the hit ball of the ball receiving portion 69 is supplied to the firing position of the firing rail 38. In this way, by attaching the automatic ball feeder 42 to the holding body 43 so as to be openable and closable,
Opening the automatic ball feeder 42 as shown in FIG. 6 has the advantage that wiping, inspection, and replacement work of the firing rail 38 are facilitated.

In order to attach the hitting and launching mechanism 37 unitized as described above to the main frame 12 of the front frame 4, first, as shown in FIGS.
a, the rotary solenoid 41 is made to face the circular mounting hole 19 formed through
Hole 21 formed in the plate-shaped portion 12a with the large-diameter head 50 of
The holding body 43 is closely fitted to the plate-shaped portion 12a by fitting into the large-diameter hole portion 21a. At this time, the regulating protrusions 88, 8 of the holding body 43
8 is fitted into the vertical slots 83 of the plate-shaped portion 12a, whereby the position of the holding body 43 is reliably regulated so as not to rattle in the left-right direction. Next, in this state, the handle piece 87 is pushed with a finger to push the holding body 43 downward, and the small-diameter base portion 51 of the fitting projection 52 and the engagement hole 21 are pressed.
With the small diameter hole 21b. When the holding member 43 is pressed down, the small projections 86 of the elastic pieces 85 are fitted into the recessed holes 89, 89 of the plate-shaped portion 12a, and the position of the holding member 43 is reliably regulated so as not to rattle in the vertical direction. . Thus, the hitting ball firing mechanism 37 can be firmly and accurately attached to the main frame portion 12 of the front frame body 4 with one touch without screwing.

In order to remove the hitting ball firing mechanism 37 attached to the main frame 12 of the front frame 4 in this manner, the holder 43 is pushed upward to remove the small-diameter base 51 of the fitting projection 52. After removing from the small diameter hole 21b of the engagement hole 21,
The large-diameter head 50 of the fitting projection 52 is connected to the large-diameter hole 2 of the engagement hole 21.
This is easily achieved by matching 1a.
