Abstract

A display device is provided. The display device includes a chassis with an opening, a touch-screen unit, which is arranged to have a first plane thereof toward the opening and is configured to accept an input operation entered through a reactive area in the first plane when the reactive area is touched, a positioning part, which is formed on the chassis and is configured to be in contact with a non-reactive area being different from the reactive area in the touch-screen unit, and a resilient member, which is configured to urge the touch-screen unit against the positioning part.

Claims

1. A display device, comprising:

a chassis with an opening;

a touch-screen unit, which is arranged to have a first plane thereof toward the opening and is configured to accept an input operation entered through a reactive area in the first plane when the reactive area is touched;

a positioning part, which is formed on the chassis and is configured to be in contact with a non-reactive area being different from the reactive area in the touch-screen unit; and

a resilient member, which is configured to urge the touch-screen unit against the positioning part.

2. The display device according to claim 1,

wherein the positioning part is arranged in a position spaced apart from a rim of the opening.

3. The display device according to claim 2, further comprising:

a sealer configured to fill clearance between the chassis and the non-reactive area in the touch-screen unit in a position between the positioning part and the rim of the opening.

4. The display device according to claim 1,

wherein the positioning part protrudes toward the touch-screen unit.

5. The display device according to claim 4

wherein the positioning part is contacted with the first plane.

6. The display device according to claim 4,

wherein the positioning part is formed in a shape of a rib, which extends along the rim of the opening.

7. The display device according to claim 1, further comprising:

an image display unit, which is arranged to face a second plane of the touch-screen unit, the second plane being on a side opposite from the first plane, and is configured to display an image therein; and

a support frame, which is configured to hold the image display unit,

wherein the resilient member is configured to be deformable and to urge the touch-screen unit via the support frame against the positioning part.

8. The display device according to claim 7,

wherein the touch-screen unit comprises:

a touch-panel including the first plane; and

a metal frame configured to hold outer rims of the touch-panel; and

wherein the metal frame is urged against the positioning part.

9. The display device according to claim 8,

wherein the metal frame and the support frame are in contact with each other.

10. The display device according to claim 7,

wherein the support frame has portions which are disposed at outer side areas of a screen of the image display unit when the support frame is installed in the display device to hold the image display unit, and

wherein the resilient member includes a plurality of resilient members, which are arranged to urge the outer side areas.

11. The display device according to claim 10,

wherein the plurality of resilient members are arranged in end positions on the support frame and in an intermediate position between the end positions on the support frame;

and

wherein urging force produced by the resilient members at the end positions is greater than urging force produced by the resilient member at the intermediate position.

12. The display device according to claim 11,

wherein the support frame projects toward the resilient members at the end positions with respect to the intermediate position.

13. The display device according to claim 7, further comprising:

a stopper, which is configured to be in contact with one of the support frame and the resilient member and is configured to restrict an amount of deformation of the resilient member.

14. The display device according to claim 1, further comprising:

a metal-planar shield member configured to cover the touch-screen unit on a side opposite from the first plane of the touch-screen unit,

wherein the shield member is fixed to the chassis with the resilient member holding thereon.

15. The display device according to claim 10,

wherein the plurality of resilient members are arranged in end positions on the touch-screen unit and in an intermediate position between the end positions on the touch-screen unit;

and

wherein urging force produced by the resilient members at the end positions is greater than urging force produced by the resilient member at the intermediate position.

16. An image forming apparatus, comprising:

an image forming unit; and

a display device, which comprises;

a chassis with an opening;

a touch-screen unit, which is arranged to have a first plane thereof toward the opening and is configured to accept an input operation entered through a reactive area in the first plane when the reactive area is touched;

a positioning part, which is formed on the chassis and is configured to be in contact with a non-reactive area being different from the reactive area in the touch-screen unit; and

a resilient member, which is configured to urge the touch-screen unit against the positioning part,

wherein the chassis is formed to have an elongated shape, of which length is greater than a length of the touch-screen unit.

17. A display device, comprising:

a chassis with an opening;

a touch-panel which is arranged to have a first plane thereof toward the opening and is configured to accept an input operation entered through a reactive area in the first plane when the reactive area is touched;

a frame, which is configured to hold outer rims of the touch-panel;

a positioning part, which is formed on the chassis and is configured to be in contact with the frame; and

a resilient member, which is configured to urge the frame against the positioning part.

18. The display device according to claim 17,

wherein the frame is contacted with a second plane of the touch-panel, the second plane being on a side opposite from the first plane.
