Abstract

A rotating shaft supporting means 3 is provided with a rotating shaft shifting means 18 for shifting a rotating shaft 2 by a predetermined distance in a predetermined direction when a display means 1 is rotated on the rotating shaft 2 to a predetermined angle. Further, the rotating shaft of the display means is electrically driven.

Claims

1. A display device including a display means, which is rotatable in opening and closing directions;

a rotating shaft of the display means; and

a rotating shaft supporting means, the display device comprising;

a rotating shaft shifting means for shifting the rotating shaft by a predetermined distance with respect to the rotating shaft supporting means in a predetermined direction when the display means is rotated to a predetermined angle on the rotating shaft.

2. The display device according to claim 1, wherein the rotating shaft shifting means shifts the rotating shaft through a combined mechanism of a rack and a pinion provided in a joint of the rotating shaft and the rotating shaft supporting means.

3. The display device according to claim 1, wherein the rotating shaft shifting means, when the display means is rotated from a closed state to an opened state, shifts the rotating shaft such that a display screen of the display means moves by a predetermined distance in an upward direction viewing from a viewer.

4. The display device according to claim 2, wherein the pinion is integrally formed with the rotating shaft and the rotating shaft is rotatably and movably engaged in a guide slot restricting a shifting direction of the rotating shaft.

5. The display device according to claim 3, wherein the pinion is integrally formed with the rotating shaft and the rotating shaft is rotatably and movably engaged in a guide slot restricting a shifting direction of the rotating shaft.

6. The display device according to claim 1, wherein the shifting direction of the rotating shaft is inclined relative to the perpendicularity.

7. A display device including a display means, which is rotatable in opening and closing directions;

a rotating shaft of the display means; and

a rotating shaft supporting means, the display device comprising;

a follower gear integrally formed with the rotating shaft, and a motor-driven driving gear geared with the follower gear.

8. The display device according to claim 7, wherein a braking means, which can stop at least rotation of the display means by moment of self-weight of the display means.

9. The display device according to claim 7, wherein a rotating shaft shifting means for shifting the rotating shaft by a predetermined distance in a predetermined direction when the display means is rotated to a predetermined angle on the rotating shaft.

10. The display device according to claim 9, wherein the rotating shaft shifting means includes a pinion, which is coaxially and integrally provided with the follower gear;

and a circular arc-like rack gear, which is coaxially formed with the driving gear, and gears with the pinion, the rotating shaft shifting means shifting the rotating shaft along a guide through a combined mechanism of the pinion and rack gear.
