Abstract

A display device is provided and includes: a display portion; a storage member configured to house the display portion and including 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 folded up and overlapped with each other at the region; and travel control means configured to cause the plurality of cover members to transfer to a first condition in which the opening is closed by the plurality of cover members and also to a second condition in which the plurality of cover members are folded up and overlapped with each other.

First claim

What is claimed is:

1. A display device comprising:
an opening;
a combiner which, in use, is raised up through the opening with information displayed thereon and which, out of use, is retracted and stored;
a plurality of divided lids including a first lid, a second lid, and a third lid which is disposed closer to an end portion of the opening than the first and second lids and which opens and closes a part of the opening by rotation action, which, in use, are configured to be folded up and stored by cover opening action to thereby open the opening and which, out of use, are configured to close the opening;
an opening and closing drive structure including a pinion and rack that is arranged in parallel with the lids, configured to open and close the plurality of lids at respective different speeds;
a support member configured to rotatably support the third lid and having a drive boss;
an elastic member configured to bias the third lid in an opening direction; and
a closing action portion configured, when the first and second lids are closed, to move the drive boss of the support member to thereby close the part of opening by the third lid.

2. A display device comprising:
a display portion configured to display information;
a storage member configured to store the display portion and comprising an opening at an upper side thereof for allowing the display portion to protrude through;
a plurality of cover members which are-configured to cover the opening and which each have a smaller surface area than the opening; comprising a first cover member comprising first bosses and a second cover member comprising second bosses;
a cover opening and closing drive structure including a pinion and a rack that is arranged in parallel with the cover member,
wherein the drive structure is configured to open and close the plurality of cover members, respectively, wherein a first condition is present in which the plurality of cover members are overlapped with one another, and a second condition is present in which the plurality of cover members close the opening;
a travel means configured to move the plurality of cover members at respective different speeds, one of when the first condition is transferred to the second condition, and when the second condition is transferred to the first condition

and
wherein the display device further comprises:
a first drive source disposed in the storage member and configured to move the travel means;
a drive shaft configured to travel in a travel direction of the cover member;
a first cam disposed parallel to a side of the storage member and configured to travel in the travel direction in accordance with a rotation action of the drive shaft and a travel action thereof in the travel direction; and
a second cam disposed parallel to the side of the storage member and configured to travel in the travel direction in accordance with the travel action of the drive shaft in the travel direction,
wherein the first cover member is engaged with the first cam by the first bosses, and the second cover member is engaged with the second cam by the second bosses.

3. A display device according to claim 2 , wherein a first guide grove is disposed on the side of the storage member and comprises:
a first horizontal portion extending in the travel direction; and
a first vertical portion connected with the first horizontal portion and extending in a first direction intersecting with the travel direction, wherein the first cam comprises a first guide hole comprising a first inclined portion extending in a second direction intersecting with the travel direction, the first boss of the first cam is engaged with the first guide groove and the first guide hole, and wherein the first cover member is transferred from the first condition to the second condition and also is transferred from the second condition to the first condition in accordance with traveling of the first cam moving in the travel direction.

4. A display device according to claim 3 , wherein a second guide groove is disposed at the side of the storage member and comprises:
a second horizontal portion extending in the travel direction; and
a second vertical portion connected with the second horizontal portion and extending in the second direction intersecting with the travel direction,
wherein the second cam comprises a second guide hole comprising a second inclined portion extending in the second direction, and the second boss of the second cam is engaged with the second guide-groove and the second guide hole, and
wherein the second cover member is transferred from the first condition to the second condition and also is transferred from the second condition to the first condition in accordance with traveling of the second cam moving in the travel direction.

5. A display device according to claim 3 , wherein an angle made between the first direction and the second direction is substantially 45 degrees.

6. A display device according to claim 2 , wherein the display device further comprises a second drive source disposed independent from the first drive source and configured to raise up and retract the display portion.

7. A display device according to claim 2 , wherein the first drive shaft comprises a pinion, and the first cam comprises a rack to engage with the pinion.
