And the support shaft 17b slip by friction. In this embodiment, the planetary gear 36 and the rack member 34
And the support shaft 17b and the guide groove 33 form a first power conversion portion 37. The first power conversion portion 37 is meshed with the gear 35 and the planetary gear 36, and the second power conversion portion 37 is formed by the drive shaft 17c and the rotation guide portion 33a. A power converter 38 is configured.

The operation of the vehicle-mounted device having the above structure will be described with reference to FIG. FIG. 6 shows a television monitor 1.
7 shows a series of operation states in which the state 7 is projected from the state stored in the case 32 to the outside of the case 32 and turned. When the drive shaft 23a of the motor 23 is driven to rotate in one direction at the illustrated storage position (a), this drive force is transmitted to the support shaft 17b via the gear 23b, the intermediate gear 26, and the gear 22,
Thus, the support shaft 17b is driven to rotate clockwise in the drawing. This rotational force is applied to the gear 3 fixed to the support shaft 17b.

At this time, the support shaft 17 is
The television monitor 17 attempts to rotate clockwise following the rotation of the b. However, since the drive shaft 17c is vertically restrained by the linear portion of the guide groove 33, the friction mechanism slips and the television monitor 17 slips. 17 does not rotate and remains in a horizontal posture. The rotation of the planetary gear 36 in the counterclockwise direction and the engagement between the planetary gear 36 and the rack 34a cause the support member 18 to move in the direction of arrow A1.

When the support shaft 17c abuts on the left end 33b of the guide groove 33 in the figure, the television monitor 17 is in a state of protruding outside the case 16 (b), and is prevented from moving in the direction A1 in the figure. In this state, since the drive shaft 17c is located at the lower end of the rotation guide portion 33a, upward movement is allowed. Therefore, when the motor 23 is continuously driven, the television monitor 17 is rotated clockwise about the support shaft 17b by the friction mechanism between the support shaft 17b and the television monitor 17. When the storage switch is operated from the standing posture of the television monitor 17 shown in (d), the motor 23 is driven in the opposite direction, and
Is turned into a horizontal state and then stored in the case 32.

A guide member 42 having a groove 42a is provided, and a support shaft 17b and a drive shaft 1 are provided.
Both ends of the guide shaft 7c may move in the guide groove 42a so that the vertical movement of the drive shaft 17c can be restricted while the support member 18 is moving in the A1 direction. In this case, as shown in FIG. 7, when the support member 18 moves to the left end in the figure, only the drive shaft 17c comes out of the guide groove 42a, and the upward movement of the drive shaft 17c is allowed. At this time, the clockwise rotating force of the gear 24 is transmitted to the planetary gear 27, and the planetary gear 27 rotates along the internal teeth 21 a of the large-diameter gear 21 due to the rotation of the planetary gear 27 in the counterclockwise direction. The monitor 17 starts up. With this structure, the tension spring 25 shown in FIG. 2 becomes unnecessary.

5 and 6, the television monitor 17 rotates clockwise together with the support shaft 17b by a friction mechanism provided between the support shaft 17b and the television monitor 17. As shown in FIG.
An arc portion 43c may be integrally formed on the left end side of FIG. 3 in the drawing, and a rack 43d may be formed on the inner periphery of the arc portion 43c. In this case, a toothless portion 43e is formed at the boundary between the arc-shaped rack 43d and the linear rack 43a. In this embodiment, when the support member 18 moves to the left end in the figure along the rack 43a, the planetary gear 36 is moved to the rack 43 of the arc portion 43c.
The drive shaft 17c rotates upward and the television monitor 17 rotates clockwise in the drawing. In this case, the friction mechanism is unnecessary.

In each of the above embodiments, the apparatus main body is a television monitor. However, display devices other than the television monitor, such as a character display device, various data display devices, a facsimile reception content display device, a navigation system display device, Alternatively, it may be a device other than the display device.
