The ball receiving portion 69 of FIG. 8 correctly faces the firing position of the firing rail 38. When the front plate 7 is closed, it is a rear cover portion 57b of the case body 57, and a ball introduction port 65 provided in the rear wall 64 and a ball outlet 80 of the ball feed tray 6 provided in the front plate 7 are provided. Is to be communicated. A positioning protrusion 81 for properly regulating the position of the automatic ball feeder 42 is provided inside the front plate 7.
And a rear cover portion 57 b of the case body 57, and a rear surface wall 64 is provided with a positioning hole 82 into which the positioning protrusion 81 is fitted.

When the electromagnet 59 is excited in synchronization with the firing operation of the hitting rod 39 by the rotary solenoid 41, the movable plate 74 is attracted by the excitation of the electromagnet 59 (see the chain line in FIG. 10). The ball supply member 58 is rotated upward (counterclockwise direction) as indicated by a chain line in FIG. 11 via the member 71, and is linked by the downward rotation (movable line position in FIG. 10) of the movable plate 74 due to the demagnetization of the electromagnet 59. The ball supply member 58 is rotated downward (clockwise) through the member 71, and the hit ball located at the head of the ball passage 67 is received by the ball receiving portion 69 and held by the upward rotation of the ball supply member 58. Then, 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 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 exposed from the front side to the circular mounting hole 15 formed therethrough.
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. By pushing down the holding body 43, the small projections 86 of the elastic pieces 85 are fitted into the concave holes 89, 89 of the holding body 43, so that the position of the holding body 43 is reliably regulated so as not to rattle in the vertical direction. by this,
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.

Further, 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 holding body 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. Then, the automatic ball feeder 42 is housed in the case body 57 and attached to the holding body 43 so as to be openable and closable, so that the automatic ball feeder 42 can be guarded from falling balls and the like, and the case body 57 is closed. Firing rail 3 at
Front cover portion 57 of case body 57 which is almost in close contact with the front edge of
a serves as a guide surface of a hit ball fired by the hitting rod 39, so that a good ball jump can be obtained. Also, as shown in FIG. 6, when the automatic ball feeder 42 is opened, the firing rail 3
There is an advantage that wiping, inspection, replacement work, and the like of FIG.

[0026]

As described above, according to the first aspect of the present invention, the firing rail, the hitting rod facing the firing position of the firing rail, and the driving source of the hitting rod are each integrated with the holder. The automatic ball feeder that supplies the hit balls stored in the hitting ball supply tray one by one to the firing position of the firing rail in conjunction with the firing operation of the hitting rod is housed in the case body, and the case body is mounted. Since the hitting ball firing mechanism is unitized by being attached to the holding body so as to be openable and closable in the front-rear direction, the unitized hitting ball firing mechanism is detachably mounted on the front frame body. The assembling work becomes very easy and the working cost can be reduced. In addition, by opening the case body, wiping and cleaning, inspection, and replacement work of the firing rail 38 can be easily performed.

Further, since the rear wall of the case body is brought into close contact with the front edge of the firing rail when the front plate is closed, the front cover portion of the case body is hit by a hitting rod. And a good ball jump is obtained.
