As described above, the first moving member 30 and the second moving member 35 are synchronously moved in the Y1-Y2 direction by the common drive mechanism unit 20. While the first moving member 30 moves from the retracted position shown in FIG. 6 to the forward position shown in FIG. 12, the display 10 advances in the Y1 direction from the state of being housed inside the housing 2 in a horizontal posture. When the rotation is completed about the reference rotation shaft 48 provided on the first moving member 30 and the rotation is completed, the screen 12a is in a standing posture with the screen 12a facing forward. On the other hand, while the second moving member 35 moves from the retracted position shown in FIG. 13 to the forward position shown in FIG. 17, the lid 4 moves from the initial posture to the first retracted posture, and further becomes the second retracted posture. After that, it returns to the operation completion posture.

6 to 12 show the relative postures of the display 10 and the lid 4 in this series of operations.

(Lid body 4 is the initial posture)
As shown in FIG. 6, when the first moving member 30 and the second moving member 35 are in the retracted positions in the Y2 direction, the lid 4 is in the initial posture. At this time, the lid 4 in the initial posture covers the display 10, and the display 10 is housed behind the lid 4 and the panel member 5. The opening width H1 of the gap 6 between the lid 4 and the panel member 5 is the minimum, and the opening width H1 is an interval at which the display 10 cannot pass.

(Lid body 4 is the first evacuation posture)
As the display 10 in the horizontal posture moves forward, the display shifts from FIG. 7 to FIG. 8, the lid 4 is in the first retracted posture, and the opening width of the gap 6 between the lid 4 and the panel member 5 is widened to H2. As a result, the display 10 in the horizontal posture can pass through the gap 6. In FIG. 9, the lid body 4 is still in the first retracted posture, but at this point, the display 10 further advances and begins to rotate so that the front end portion 15 faces upward.

(Lid body 4 is in the second evacuation posture)
When the display 10 is further advanced from FIG. 9 and the rotation angle of the display 10 gradually increases, the lid 4 rotates clockwise from the first retracted posture as shown in FIGS. 10 and 11. After moving, the lid 4 further retracts in the Y2 direction to take the second retracted posture, and the opening width of the gap 6 expands to the maximum H3.

The lid 4 rotates clockwise from the initial posture shown in FIG. 6 to the first retracted posture shown in FIG. 9, and moves backward (Y2 direction). As shown in FIG. 6, the height difference between the front end portion 4a and the rear end portion 4b located above the front end portion 4a of the lid body 4 in the initial posture is h1, but as shown in FIG. 9, the lid body When 4 is in the first retracted posture, the difference in height becomes small from h1 to h2. The lid 4 further rotates clockwise and moves rearward while going from the first retracted posture shown in FIG. 9 to the second retracted posture shown in FIG. In the lid 4 in the second retracted posture, the height difference between the front end portion 4a and the rear end portion 4b located above this is further narrowed from h2 to h3. h1>h2> h3.

As shown in FIGS. 8 and 9, until immediately after the display 10 advances in the Y1 direction in a parallel posture and the display 10 starts to rotate, the posture switching mechanism unit 40 uses the control arm portion 14 provided on the display 10 to move forward. The posture is such that the second link member 42 stands up in the Z1 direction, and the front end on the Y1 side stands up so that the connecting shaft 46 is located above the control shaft 45. Further, the connecting shaft 46 connecting the control arm portion 14 and the second link member 42 moves in the Y1 direction at a position separated above the display 10.

In the states shown in FIGS. 8 and 9, the lid 4 in the first retracted posture is in the forward tilted posture in which the height difference between the front end portion 4a and the rear end portion 4b is h2, so that the lid 4 is connected to the control arm portion 14. The 46 and the second link member 42 can enter the lower side of the lid 4 in the forward leaning posture from the rear. However, if the control arm portion 14, the connecting shaft 46, and the second link member 42 try to move forward in the Y1 direction further than the posture shown in FIG. 9, any one of the control arm portion 14, the connecting shaft 46, and the second link member 42 Will hit the lower surface of the lid 4 in the second retracted posture.

Therefore, as shown in FIGS. 10 to 11, in the second retracted posture, the lid 4 rotates clockwise, and the height difference h3 between the front end portion 4a and the rear end portion 4b becomes smaller, so that the lid The body 4 is in a posture closer to the horizontal posture than the forward leaning posture of the initial posture and the first retracted posture. As a result, the control arm portion 14, the connecting shaft 46, and the second link member 42 can move forward under the lid body 4.

Further, the lid 4 in the second retracted posture retracts in the Y2 direction, and the opening width of the gap 6 between the lid 4 and the panel member 5 widens to the maximum H3. Therefore, as shown in FIGS. 10 and 11, the display 10 can start rotating so that the front end portion 15 faces upward while advancing in the Y1 direction.

(The rotation completion posture of the display 10 and the operation completion posture of the lid 4)
As shown in FIG. 12, when the first moving member 30 moves to the forward position which is the end in the Y1 direction, the control shaft 45 connecting the first link member 41 and the second link member 42 becomes a fixed cam member. It moves to the terminal control unit 47c of the attitude control cam unit 47 formed on the 43, and the first link member 41 rotates counterclockwise to the maximum angle. As a result, the control arm portion 14, the connecting shaft 46, and the second link member 42 are aligned linearly in the Y1-Y2 direction, and the control arm portion 14, the connecting shaft 46, and the second link member 42 are first. The display 10 is rotatably supported by the moving member 30 so as to be parallel to the tip portion 30a, and the control arm portion 14, the connecting shaft 46, the second link member 42, and the tip portion 30a are aligned in the X1-X2 direction. Will be.

As shown in FIG. 12, when the display 10 is in the rotation complete posture, the lid 4 is rotated in the counterclockwise direction to be in the operation complete posture. When the operation is completed, the posture is the same as the initial posture shown in FIG. 6, and the opening width of the gap 6 between the lid 4 and the panel member 5 is H1. The control arm portion 14, the connecting shaft 46, the second link member 42, and the tip portion 30a of the first moving member 30 are located in the gap H1.

That is, the opening width H1 of the gap 6 between the lid 4 and the panel member 5 is the thickness dimension of the display 10 when the lid 4 is in the initial posture shown in FIG. 6 and when the operation completion posture is shown in FIG. Although narrower than the above, when the display 10 is in the rotation completed posture, the control arm portion 14, the connecting shaft 46, the second link member 42, and the first moving member 30, which are a part of the posture switching mechanism portion 40, The size is set so that a part of the tip portion 30a can intervene.

In the in-vehicle display device 1, as shown in FIG. 1, since the opening width H1 of the gap 6 between the lid 4 in the initial posture and the panel member 5 can be minimized, when the passenger in the vehicle sees it, The inside of the panel member 5 can be made difficult to see through the gap 6. Further, as shown in FIG. 2, when the display 10 stands up in the rotation completion posture, the lid 4 in the operation completion posture is in the same posture as in the initial posture shown in FIG. There is a difference between the state and the state of FIG. 2 whether or not the display 10 exists, but other changes do not occur.

That is, in the state of FIG. 2, it is possible to give an appearance as if the lid 4 is not moving, and it is possible to maintain a high-class feeling in the appearance of the instrument panel and the dash board. In particular, when the width dimension of the lid 4 and the panel member 5 in the X direction is larger than the width dimension of the display 10, the panel members 5 located on both sides of the display 10 in the X direction in FIGS. 1 and 2. Since the lid 4 is in the same state, it is possible to maintain a high-class appearance in the appearance of the instrument panel and the dash board.

Further, as shown in FIG. 2, when the display 10 is in the rotation completed posture, the opening width of the gap 6 is as narrow as H1, so that it is difficult for foreign matter to enter the lower side of the lid 4.

As shown in FIG. 12, the first moving member 30 and the second moving member 35 are moved in the Y2 direction by reversing the motor 23 from the state where the display 10 is in the rotation completed posture and the lid is in the operation completed posture. Then, as shown in FIG. 6, the display 10 is in the retracted posture and the lid is in the initial posture.
