FIG. 5 shows that notches 55, 55 are provided at the base of each of the locking pieces 41b, 41b of the upper side frame 27b in the terminal box 21, and an engagement hole is formed in the upper surrounding frame 42b also on the mechanism plate 6 side. Notches 56, 5 communicating with 44, 44
6, the terminal box 21 can be easily attached to or detached from the mechanism plate 6 in the same manner as described above.

FIGS. 6 and 7 show the mounting structure of the terminal box 20 mounted on the lower part of the mechanism plate 6. FIG. The terminal box 20 is also composed of a cover body 28 'made of synthetic resin with the rear surface opened by surrounding the front plate 25' with a side frame 27 ', and a wiring board 29' is arranged in the cover body 28 '. . The wiring board 29 ′ abuts on the rear end surface of the support cylinder 30 having a screw hole and protruding from the rear surface of the front plate 25 ′, and is fixed to the rear end surface by fixing the screw 31. Also, the power supply terminal 47, the speaker terminal 48, the ball cutting motor terminal 49, etc., which are exposed to the outside through the openings 25'a, 25'a... A firing motor power supply terminal 50 is provided for each. Reference numeral 51 denotes a connection terminal for connecting a wiring to the terminal box 21 via the connector 22.

A locking piece 52a having a hook-like portion 40 at the center thereof is provided on the outer surface of the right frame 27'a. Two locking pieces 52b having hook-shaped portions 40, 40 at the ends on both sides thereof,
52b is integrally extended. Further, a flat plate portion 53 having substantially the same size as the terminal box 20 is formed on the mechanism plate 6, and the four corners of the flat plate portion 53 can receive the wiring board 29 'in the terminal box 20 as described above. Support cylinders 54, 54,... An engagement hole 44 is formed on the right side of the flat plate portion 53 at a position corresponding to the locking piece 52a, and two engagement holes are formed on the left side at a position corresponding to the locking pieces 52b, 52b. Holes 44, 44 are opened.

First, the hooks 40, 40 at the tips of the locking pieces 52b, 52b are engaged with the two engagement holes 44, 44 on the left side, and then the locking piece 52a is pushed into the engagement hole 44 on the right side. To engage. Also in this case, the internal wiring board 29 '
The four corners are received by the support cylinders 54, 54,.
Since the opposite side is received by the support cylinder 30 to which the screw 31 is fixed, it is fixed firmly without rattling. Therefore, also in this case, when connecting the connector 22 at the tip of the wiring to the connection terminal 51, the wiring board 29 'does not bend significantly, and the damage can be prevented. When the terminal box 20 is removed, the right locking piece 52
a from the holding engagement hole 44 against the resilient force.
Then, the hooks 40, 40 are pulled out from the engagement holes 44, 44 on the left side. Thus, the work of attaching and detaching the terminal box 20 can be easily performed as described above.

[0019]

As described above, according to the present invention, since a plurality of support portions capable of receiving the wiring board arranged in the terminal box from the rear side are protruded from the mechanism plate, the connector is connected to the connection terminal. At the time of mounting, the wiring board does not bend significantly, whereby an accident such as breakage of the wiring board can be eliminated.

If a supporting portion is projected from the back surface of the terminal box and the wiring board is fixed to the supporting portion, the wiring portion is held by the supporting portion and the bending thereof is further suppressed. The effect of preventing a wiring board from being damaged is greatly improved.
