<Operation> Next, a procedure for accommodating and reproducing a CD in the case 1 will be described.

(A) Opening and closing the front panel First, the front panel 1 in the recess 87b of the panel frame 87 is opened.
In order to open 00, the open / close switch 127 of FIG. 9 provided on the front surface of the front panel 100 is pushed, and the panel motor 1
Rotate 03. Then, in FIG. 10, the rotation of the panel motor 103 is changed from the worm 117 to the wheel 118.
Through 121 to the large gear 106 on the left side, and through the gear 113 and the shaft 102, the large gear 10 on the right side.
6, the pair of large gears 106 simultaneously rotate in the same direction. At this time, since the pin 107b moves to the outside of the large gear 106 along the spiral groove 106b of the large gear 106, the toothed lever 107 rotates about the shaft 107a, and the portion of the tooth 107c moves to the front side. . For this reason,
Toothed lever 1 having teeth 111a that mesh with teeth 107c
The drive arm 109 in which 11 is integrated is a shaft 109a.
And the tip of the drive arm 109 descends from the top to the bottom in front of the panel frame 87. A mounting plate 98 is coupled to the tip of the drive arm 109, and the mounting plate 98
The tip of the driven arm 110 is coupled to the
When the front panel 100 is in the closed state as shown in (a), the rotation connecting portion 141 of the driven arm 110 is positioned above the rotation connecting portion 141 of the drive arm 109.
The position of the shaft 110a at the base end of the driven arm 110,
The length of the driven arm 110 is set. And
When the panel motor (panel driving means) 103 is driven from the closed state of the front panel 100, the drive arm 109 and the driven arm 110 rotate about the shaft 109a and the shaft 110a at the base end portions, respectively. 14 to the fully open state of the front panel 100 shown in FIG. 15 through the half open state of the front panel 100. When the front panel 100 is fully open, the driven arm 11
0 is pulled by the mounting plate 98 to the position of FIG. 15 against the biasing force of the spring 112. Then, when the dog 106c of the left large gear 106 shown in FIG. 10 of the front panel 100 attached to the attachment plate 98 pushes the limit switch 124, the rotation of the panel motor 103 is stopped. When the front panel 100 is open, the worm 117 cannot be turned from the wheel 118, and it is difficult to turn the large gear 106 from the pin 107b.
0 is in a restrained state, and the switches on the front panel 100 can be easily operated.

By the way, as shown in FIG. 13B, the bearing hole 142 of the drive arm 109 and the driven arm 110.
The outer space L1 between the bearing holes 142 of the drive arm 10 is
9. The outer distance between the shaft 144 of 9 and the shaft 144 of the driven arm 110
It is set to a value obtained by adding the play gap G to L2. This value is kept constant both when the front panel 100 is closed and when it is fully opened. Needless to say, the play gap G is indispensable for smoothly rotating the shaft 144 with respect to the mounting plate 98.

However, if the play gap G exists when the front panel 100 is fully opened, the front panel 100 will be exposed when an operating force (pressing force) is applied when operating the operator (switch) or the like provided on the front panel 100. It will bend. In particular, in an in-vehicle device such as a car stereo, the front panel 10 tends to use a so-called heavy touch operator in order to clarify the operation touch.
There is a possibility that the deflection of 0 may increase and cause the operation feeling to deteriorate.

FIG. 22 shows an embodiment in which the play gap G can be prevented by substantially eliminating the play gap G when the front panel 100 is fully opened. In this embodiment, the outer space L1 between the bearing hole 142 of the drive arm 109 and the bearing hole 142 of the driven arm 110 in the closed state of the front panel 100 is the outer side of the shaft 144 of the drive arm 109 and the shaft 144 of the driven arm 110. It becomes a value obtained by adding the play gap G to the gap L2, and the outer gap L3 between the bearing hole 142 of the drive arm 109 and the bearing hole 142 of the driven arm 110 when the front panel 100 is fully opened is equal to the gap L of the drive arm 109. The shaft 144 and the shaft 144 of the driven arm 110
The outer gap L2 of the above plus the play gap 2G (L3
The movement locus R1 of the tip end portion (bearing hole 142) of the drive arm 109 and the movement locus R2 of the tip end portion (bearing hole 142) of the driven arm 110 are set so that ≧ L2 + 2G).

Specifically, when the driven arm 110 is rotated to a position where the front panel 100 is fully opened, the projection 151 provided on the driven arm 110 abuts the projection abutment portion 152, and the driven arm 110 is driven. The arm 110 is adapted to slightly move in a direction in which the gap between the bearing hole 142 of the arm 110 and the bearing hole 142 of the drive arm 109 is enlarged.

Therefore, in the fully open position of the front panel 100, the play gap G is substantially eliminated, and the bending of the front panel 100 caused by the existence of the play gap G is eliminated, and the front panel 100 is eliminated.
It is possible to improve the operability and operation feeling of the operator (switch) provided in the.
