The engagement height is at the base end side of the engagement piece 931b.
So that it is equal to or slightly smaller than the thickness of the mounting surface
It is set (see FIG. 18). For this reason, the engagement operation
It is light at the beginning of the operation, and engages securely near the completed state of engagement.
It has become so. The case-side engaging portion 931 and the base frame
As the engagement state with the body-side engagement portion 831 progresses,
The lock claw 934 of the plate case 930 is
Over the lock part 834b of the lock arm 834 on the side
Move downwards. At this time, the lock arm 834 is
Inclined part 934a of the locking claw 934 and the locking part 93
4b, the arm portion 834a is elastically deformed forward.
The locking piece 934b is bent and bent near the engagement completed state.
When elasticity exceeds the lock portion 834b, the elastic force and the original state
And the lock piece 934b and the lock 844b
The substrate case 930 is locked in the engaged state by being engaged.
You. The removal of the board case 930 is as described above.
The procedure is reversed, and the lock portion 834 of the lock arm 834 is used.
b is pushed forward to lock part 834b and lock piece 83
4b is released, and the board case 93 is kept in this state.
0 is pressed upward, and the guided portion 938 is moved to the guide space 83.
8s and slide it up and down
Piece 931b on the case side and the piece on the base frame side
831b. Next, the board case 93
0, and pulls the guide portion 938 toward the introduction portion 8.
38c, the substrate case 930 is
It is removed from the mounting part 83. For this reason, the board case 930 has a lamp / sound
It is detachable from the board mounting part 83 of the voice control board.
As a result, the lamp / voice control board 93 is attached to and detached from the base frame 30.
Can be interchangeably mounted. In addition, in this embodiment,
At the attachment part, the left rear end face of the window 31 and part of the upper and lower parts are used.
Window area of window 31 (acceptable to window
The main control board
Ramp / voice control on substantially the same plane as 91 and the prize ball control board 92
The control board 93 can be mounted. In addition, installation of this lamp / voice control board
The connection part 83 also includes the main control board and the prize ball control base described above.
The shield plate 730 is similar to the mounting portions 81 and 82 of the plates.
It is configured to be removable. FIG. 22 shows a shield plate 730.
As shown in the mounting structure of FIG.
The base-side engaging portion 931 can pass through and attach the substrate case 930.
Penetration with a size that does not allow the case side engaging portion 931 to come into contact when detached
Holes 731 are formed at two locations above and below. Also seal
The left side of the plate 730 is aligned with the lock arm 834
As a result, a lock concave portion 734 with which the lock portion 834b can engage is formed.
Is formed. Shield plate attachment 836
The configuration of the lot hole 736 depends on the mounting / dismounting direction of the board case 930.
The direction has been changed to match the vertical direction
However, these detailed configurations and operations are
The configuration is the same as that of the mounting plate 710. The shield plate 730 is attached to the substrate mounting portion 83.
When attaching, the upper and lower shield plate engaging portions 836
Align the head with the passage hole of the slot hole 736
Cover so as to cover the upper surface of the substrate mounting portion 83, and
While pressing the shield plate 730 forward,
Ride the slot hole 736 and the shield plate
836 is engaged. At this time, the lock arm 834 is
The locking portion 834b is pressed against the back of the shield plate 730.
It is elastically deformed, and the lock portion 834b is once retracted forward.
Thereafter, the pressing force is released by the downward movement of the lock concave portion 734.
The arm 8 is restored to its original state by the elastic force of the arm and the lock 8
34b and the lower side of the lock concave portion 734 are engaged with each other to form a shield.
The plate 730 engages with the substrate mounting portion 83 and holds the lock.
Is done. On the other hand, on the back side of the board case 930,
As shown in FIG. 16, the ribs 935 (935a to 935c, 9
35α to 935ε) are integrally formed. Rib 935
Are peripheral ribs erected on four sides around the base member 930a.
