By the movement of the movable case 21 and the movable bracket 22 in the A1 direction, the guide pin 25 projecting on the bottom portion 20b of the fixed case 20 is moved in the A2 direction from the position shown in FIG. Move relative to.
When the moving case 21 moves forward in the A1 direction by a predetermined distance, the guide pin 25 moves the lock arms 42, 42 as described above.
The lock arms 42, 42 are rotated by being inserted into the arc portions 42c of the guide grooves 42b, 42b. By the operation of the lock arms 42, 42, the fixed case 20 and the movable case 21 are locked, and at the same time, the movable bracket 22 is moved.
The pin member 52 is detached from the pin holding portion 42g of the lock arms 42, 42, and the locked state between the moving bracket 22 and the moving case 21 is released. As a result, the moving case 21 is stopped at the position shown in FIG. 9, and thereafter, only the moving bracket 22 advances on the moving case 21 in the A1 direction.

That is, the case 2 is moved to the position shown in FIG.
When the 1 moves, the first fixed to the fixed case 20
The end portions of the rack member 24 and the second rack member 35 fixed on the moving case 21 are substantially continuously arranged. Therefore, when the moving case 21 is moving forward in the fixed case 20 in the A1 direction, the large gear 45 meshes only with the first rack member 24 on the fixed case 20 to roll, and the driving force causes the moving bracket to move. 22 moves forward together with the moving case 21 in the A1 direction. Then, as shown in FIG. 9, the fixed case 20 and the movable case 21 are locked, and the movable case 21 and the movable bracket 2 are locked.
When the lock with the second gear 2 is released, the large gear 45 then transfers from the first rack member 24 to the second rack member 35 on the moving case 21, and thereafter, due to the rotational force of the large gear 45, the moving case 21 moves. The moving bracket 22 moves forward in the A1 direction.

As described above, the moving case 21 and the moving bracket 22 are integrally moved to the position shown in FIG. 9 on the fixed case 20, and then the moving case 21 is locked to the fixed case 20 so that only the moving bracket 22 is moved. The motor 49 continues to rotate continuously while advancing in the A1 direction, and the advancing of the moving case 21 and the moving bracket 22 integrally and the subsequent moving of the moving bracket 22 alone are performed as a series of operations. Further, in the series of forward movements described above, as shown in FIGS. 4, 5, 9 and 10, the rollers 38 of the link member 34 provided on the television monitor 33 are provided on both side walls of the moving case 21. The television monitor 33 is supported by the guide member 39 so that the television monitor 33 moves in the A1 direction while maintaining a horizontal posture.

In the state shown in FIG. 9, the movable case 21 is locked to the fixed case 20, and the movable bracket 22 is further attached.
When only one moves forward to the position shown in FIG. 11 and FIG. 12, at this position, the third protrusion protruding to the side surface of the television monitor 33 is displayed.
Guide member (third fulcrum) 32 comes into contact with the opening-side end portion 29a of the second guide groove (regulating guide portion) 29, that is, the limit position. By this abutment, the movement of the television monitor 33, which has been moving in the horizontal state until now, in the same posture in the A1 direction is restricted. Even after the moving bracket 22 moves to the positions shown in FIGS. 11 and 12, the motor 49 continues to be driven, and the moving bracket 22 further advances in the A1 direction.

By moving the moving bracket 22 forward,
The moving case 2 is provided so as to project from the side surface of the television monitor 33.
The first guide member (first fulcrum) 30 inserted in the first guide groove 28 formed in the first sidewall moves further in the first guide groove 28 in the A1 direction. By the movement of the first guide member 30, the link member 34 and the television monitor 33 are given a turning force in the counterclockwise direction in the drawing with the third guide member 32 as the center.

That is, the TV monitor 33 is fixed to the fixed case 2.
0, the third guide member 32 is regulated by the tip of the second guide groove 29 as shown in FIG. 12, so that the advancing force of the moving bracket 22 in the A1 direction thereafter. As a result, counterclockwise turning force starts to act on the TV monitor 33. Then, as shown in FIG. 14, the first guide member 30 causes the curved portion 28 of the first guide groove 28 to move.
At the time of moving to a, the start-up of the television monitor 33 is completed. That is, when the first guide member 30 moves forward in the first guide groove 28, the link member 34 rotates counterclockwise about the guide member 32 as a fulcrum, and the link member 34 and the television monitor 33 are connected to each other. When the guide member 30 is relatively rotated by the pin member 44 serving as the connection fulcrum and the guide member 30 is moved to the curved portion 28a in the front portion of the guide groove 28, the television monitor 33 is raised to the posture shown in FIG.

Further, the click member 36 described above is biased in the upward direction in the figure by springs 37, 37 on the curved portion 28a of the guide groove 28. Therefore, the first
The guide member 30 is intermittently held in the recesses 36e to 36g formed on the click member 36, whereby the television monitor 33 is rotated while the television monitor 33 is rotated from the horizontal posture to the rising posture. The rotating operation is intermittently locked temporarily. Such a click mechanism 4
With 0, the rising posture of the television monitor 33 can be set to an arbitrary angle.

When the television monitor 33 starts to rise, the roller 38 provided on the link member 34 comes out upward from the opening 39a at the upper front end of the guide member 39 provided on the moving case 21. The contact piece 34a formed on the link member 34 contacts one end 21e of the bent portion 21d of the moving case 21 when the first guide member 30 moves to the first recess 36g of the click member 36. In contact with each other, the link member 34 exerts a stopper function of restricting further rotation in the counterclockwise direction from the posture of FIG.

To automatically set the rising angle of the television monitor 33, for example, the guide member 39 shown in FIG. 2 is used to form the reflecting member 53 in correspondence with the recesses 36e to 36g formed in the click member 36. In addition, an optical sensor 55 (see FIGS. 9 and 11) is arranged on the movable bracket 22 as a detection member so as to face the reflection member 53. Then, the signal from the optical sensor 55 is input to a control unit (not shown), and the control unit determines the order of the signal input from the optical sensor 55 to stop the driving of the motor 49. , The television monitor 33 can be automatically set to any starting posture. When the startup attitude of the television monitor 33 is not automatically set, the startup attitude may be changed manually.

In the case of a vehicle-mounted display device having the above-described structure, the television monitor 3 can be used like a conventional device of the same type.
Even if 3 is not completely projected to the outside of the fixed case 20,
Attach the TV monitor 33 to the outside of the fixed case 20 (A
It can be started and driven while moving in one direction). Therefore, it is possible to reduce the protruding size of the television monitor 33 protruding outside the fixed case 20.
