Abstract

A display device includes: a display portion; and a storage member configured to house the display portion and including an opening through which the display portion passes, wherein the display device further includes: a plurality of cover members configured to cover the opening and to travel from the opening to a region of the storage member adjacent to the opening so as to be overlapped with each other at the region; travel control means configured to cause the plurality of cover members to transfer to a covering position in which the opening is closed by the plurality of cover members, and also to a overlapping position in which the plurality of cover members are overlapped with each other, and configured to cause the display portion to transfer to rise-up and storage positions; and only one drive source configured to drive the travel control means.

First claim

What is claimed is:

1. A display device comprising:
a display portion;
a storage member configured to house the display portion and comprising an opening through which the display portion passes;
a plurality of cover members configured to cover the opening and to travel from the opening to a region of the storage member adjacent to the opening so as to be overlapped with each other at the region;
a travel control mechanism configured to cause the plurality of cover members to transfer between a covering position, in which the opening is closed by the plurality of cover members, and an overlapping position, in which the plurality of cover members are overlapped with each other, and configured to cause the display portion to transfer between a rise-up position and a storage position; and
only one drive source configured to drive the travel control mechanism,
wherein the travel control mechanism comprises: a rotary body rotated by drive force of the drive source; a first travel body configured to travel by rotation of the rotary body in a travel direction of the plurality of cover members to move the plurality of cover members; and a second travel body configured to cause the display portion to transfer between the rise-up position and the storage position in accordance with the rotation of the rotary body, and
wherein the display device comprises a lever engaged with the rotary body and configured to move the first travel body, and
wherein the rotary body has a partial gear and a guide rib to control the second travel body.

2. A display device according to claim 1 , wherein the travel control mechanism moves the plurality of cover members at respective different speeds.

3. A display device according to claim 1 , wherein each of the plurality of cover members has a surface area smaller than an area of the opening, and a total surface area of the plurality of cover members is larger than the area of the opening.

4. A display device according to claim 1 , wherein when the plurality of cover members are disposed in the overlapping position, one of the plurality of cover members with a longer travel distance of the plurality of cover members is located below another one of the plurality of cover members with a shorter travel distance.

5. A display device according to claim 1 , wherein the plurality of cover members comprise a first cover member comprising first bosses, which are disposed on opposing sides of the first cover member so as to protrude outwardly, and the second cover member comprising second bosses, which are disposed on opposing sides of the second cover member so as to protrude outwardly, the drive source is a motor, a first cover travel body comprising first guide holes having the first bosses set therein and configured to be moved by the first travel body thereby moving the first cover member, a second cover travel body comprising second guide holes having the second bosses set therein and configured to be moved by the first travel body thereby moving the second cover member, and a cover guide body comprising a third guide hole having the first bosses set therein and a fourth guide hole having the second bosses set therein and configured to guide the first cover travel body and the second cover travel body.

6. A display device according to claim 5 , wherein the first guide holes and the second guide holes comprise first inclined portions and second inclined portions, respectively, which are inclined with respect to the travel direction.

7. A display device according to claim 6 , wherein the first guide holes and the second guide holes each comprise parallel straight line portions, which are continuous respectively with at least one end of the first inclined portions and the second inclined portions and which are parallel to an upper surface of the storage member.

8. A display device according to claim 5 , wherein the first travel body comprises a drive shaft to move the plurality of cover members, the first cover travel body comprises a rack, and the drive shaft comprises a pinion to engage with the rack of the first cover travel body thereby moving the first cover travel body.

9. A display device according to claim 5 , wherein the lever comprises a first lever and a second lever that work in combination to move the first travel body in a first direction or a second direction based on a rotation direction of the rotary body.

10. A display device according to claim 9 , wherein when the plurality of cover members are moved to the storage position, a boss disposed at the second lever is set in a lock guide groove of a base so as to be maintained thereby stopping travel of the second lever and the first lever, whereby the plurality of cover members are kept in the storage position.

11. A display device according to claim 1 , wherein the second travel body comprises a display portion driving gear portion to drive the display portion and an angle detection gear portion having a shorter gear pitch than the display portion driving gear portion and configured to engage with a gear portion of an angle detector to detect the rise-up position of the display portion.

12. A display device according to claim 1 , wherein the display device comprises a covering position detection mechanism to detect the covering position by using a position of the travel control mechanism.

13. A display device according to claim 1 , wherein the display device comprises a biasing mechanism to bias the display portion in a retraction direction of the display portion when the display portion is raised up.

14. A display device according to claim 1 , wherein the travel control mechanism moves the plurality of cover members from the overlapping position to the covering position such that each of the plurality of cover members reach the covering position at a same timing, and also moves the plurality of cover members from the covering position to the overlapping position such that each of the plurality of cover members reach the overlapping position at a same timing.

15. A display device comprising:
a display portion to display information;
a storage member configured to house the display portion and comprising an opening through which the display portion passes;
a plurality of cover members configured to cover the opening, each thereof having a surface area smaller than an area of the opening;
a travel control mechanism to open and close each of the plurality of cover members;
the plurality of cover members traveling between an overlapping position in which the plurality of cover members are overlapped with each other, and a covering position in which the opening is closed by the plurality of cover members; and
a drive source configured to drive the travel control mechanism to raise up and store the display portion and also to open and close the plurality of cover members;
wherein the travel control mechanism comprises: a rotary body rotated by drive force of the drive source; a first travel body configured to travel by rotation of the rotary body in a travel direction of the plurality of cover members to move the plurality of cover members; and a second travel body configured to cause the display portion to transfer between a rise-up position and a storage position in accordance with the rotation of the rotary body;
wherein the display device comprises a lever engaged with the rotary body and configured to move the first travel body, and
wherein the rotary body has a partial gear and a guide rib to control the second travel body.

16. A display device according to claim 15 , wherein the travel control mechanism is config
