The slip clutch mechanism is provided between the large gear 34a and the small gear 34b of No. 4 respectively.

As shown in FIG. 3, a first detection member 23 of a push switch is provided on the inner surface of the first housing 11, and the first detection member 23 is provided on a side surface of the second housing 16. Detection member 2
3, detection holes 16a and 16b are formed. In addition, on the front of the fixed panel 13,
A second detection member 25 and a third detection member 26, each of which is a push switch for detecting the posture of the camera, are provided.

The operation of the vehicle-mounted electronic device 10 will be described below. 1 and 3, the second housing 16
Are retracted inside the first housing 11, and the open / close panel 12 is in a closed posture that covers the front surface of the second housing 16 that has receded. In this state, when the start operation member 12b provided on the surface 12a of the opening / closing panel 12 is pressed, the motor 19 of the drive unit is started by the control operation of the control unit in the first housing 11. The power of the motor 19 is transmitted to the gear group shown in FIG. 4 and applied to the bevel gear 37a, and a rotational force is applied to the bevel gear 21 fixed to the open / close panel 12 so that the open / close panel 12 moves from the closed position shown in FIG. It turns so that it may be turned upside down, and as shown in FIG.

In synchronism with the reversing operation of the open / close panel 12, the rack 20 is driven by the small gear 33b of the pinion gear 33.
Is supplied with forward power in the Y1 direction, and the second housing 16 moves forward from the first housing 11.

When the first detection member 23 shown in FIG. 3 detects the rear detection hole 16b, the second housing 16 cannot move forward any more. Therefore, the first detection member 23 detects the detection hole 16b, and the second detection member 25 and the third detection member 26 are in the inverted position.
Is detected, the motor 19 stops.

Here, the forward movement of the second housing 16 is completed, the timing at which the rear detection hole 16b is detected by the first detection member 23, and the opening / closing panel 12 assumes the inverted posture of FIG. There may be a difference between the timing and the timing detected by the third detection member 26. At this time, the slip clutch between the large gear 33a and the small gear 33b of the pinion gear 33 or the large gear 34a of the first transmission gear 34
The slip clutch between the gear and the small gear 34b slips, thereby absorbing the timing shift.

Also, when the opening / closing panel 12 during the reversing operation is pressed by hand, or when the second housing 16 during the forward movement is pressed by hand, the slip clutch operates and the motor 19 is forced. It is prevented from being stopped temporarily.

In the state shown in FIG. 2, the front surface of the second housing 16 is
The detection hole 16b is formed so that the same position as the surface 12c of the opening / closing panel 12 in the inverted posture, preferably the front surface of the second casing 16 moves forward from the surface 12c. As a result, the front surface of the second housing 16 is located in a vacant area below the open / close panel 12 that has been turned upward, and the operating member 17 provided on the front surface of the second housing 16
And the position of the insertion port 18 can be easily visually confirmed by a line of sight from obliquely above. Therefore, the operation member 17 can be reliably operated, and a recording medium such as a disc can be easily inserted from the insertion port 18.

When the apparatus is to be stopped from the state shown in FIG. 2, one of the operation members 17 provided on the front surface of the second housing 16 is operated. When this operation signal is given to the control unit, the motor 19 of the driving means rotates in the reverse direction, and a moving force in the Y2 direction is given to the rack 20, so that the second housing 16 is moved into the first housing 11. fall back. In synchronization with this, a rotating power is applied to the bevel gear 21, and the opening / closing panel 12 rotates from the inverted posture shown in FIG. 2 to the closed posture shown in FIG.

The first detecting member 23 detects the detecting hole 16a located in front of the second housing 16, and the second detecting member 25 detects the open / close panel 12 in the closed position. At this point, the motor 19 stops. At this time, even if the timing of the completion of the retreat operation of the second housing 16 and the timing of the completion of the opening / closing panel 12 to the closed position are shifted, the motor 19 is forcibly stopped by the operation of the slip clutch. Can be prevented.

[0044]

As described above, according to the present invention, the first
When the movable part is turned upside down, the second movable part moves forward in a region below the movable part, so that the position of the operation part and the like provided in the second movable part is visually observed obliquely from the upper front. It will be easier.
