When the supply member 58 is rotated downward, the hit ball of the ball receiving portion 69 is supplied to the launch position of the launch rail 38.
[0024]
In order to attach the hitting ball launching mechanism 37 unitized as described above to the main frame portion 12 of the front frame body 4, first, as shown in FIGS. 8 and 12, the plate-like portion 12 a of the main frame portion 12 is penetrated. The rotary solenoid 41 faces the circular mounting hole 15 from the front side, and the large-diameter head portion 50 of the fitting protrusion 52 is fitted into the large-diameter hole portion 21a of the engaging hole 21 formed in the plate-like portion 12a. Then, the holding body 43 is brought into close contact with the plate-like portion 12a. At this time, the restricting protrusions 88 and 88 of the holding body 43 are fitted into the longitudinal groove holes 83 and 83 of the plate-like portion 12a, so that the holding body 43 does not rattle in the left-right direction. Thus, the position is surely regulated. 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 protrusion 52 and the small-diameter hole portion 21b of the engaging hole 21 are engaged. When the holding body 43 is pushed down, the small protrusions 86 of the elastic piece 85 are fitted into the recessed holes 89, 89 of the holding body 43, so that the position of the holding body 43 is reliably regulated so that the holding body 43 does not rattle in the vertical direction. Thereby, the hitting ball launching mechanism 37 can be firmly and accurately attached with one touch without being screwed to the main frame portion 12 of the front frame 4.
[0025]
Further, in this way, in order to remove the hitting ball launching mechanism 37 attached to the main frame portion 12 of the front frame body 4, the holding body 43 is pushed upward and the small-diameter base portion 51 of the fitting protrusion 52 is engaged with the engagement hole. After being removed from the small-diameter hole portion 21 b of 21, the large-diameter head portion 50 of the fitting protrusion 52 is made to coincide with the large-diameter hole portion 21 a of the engaging hole 21. Then, the automatic ball feeding device 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 feeding device 42 can be guarded from a spilling ball and the case body 57 is closed. so that good ball jump becomes the guide surface of the ball to be fired cover portion 57a after the dense Chakusuru case body 57 by hitting rod 39 to the front edge of the firing rail 38 is obtained in. Further, if the automatic ball feeding device 42 is opened as shown in FIG. 6, there is an advantage that wiping cleaning, inspection, replacement work and the like of the firing rail 38 are facilitated.
[0026]
