Abstract

There has been a problem with a film provided on a surface of an input section such as a touch panel etc., which is arranged on a display such as a conventional type of liquid crystal display or the like is swelled or corrugated owing to deterioration with the lapse of time, or change in temperature and humidity.

According to the present invention, there is provided an information input display device. The device comprises a drawing action section which generates tension to draw outward directly or indirectly by elasticity in a film, when an input section capable of displaying in a transmittable manner, which is arranged on a surface of a display section, is attached to an housing. The device prevents swelling or corrugation of the film from occurring by the tension.

Claims

1. An information input display device, comprising:

a display section to indicate information;

an input section arranged on a surface of the display section and capable of displaying the information in a transmittable manner; and

a casing to contain the display section and the input section, wherein

the input section comprises;

a base material capable of displaying in a transmittable manner;

a film capable of displaying in a transmittable manner; and

an adhesive to adhere a surrounding portion of the film to the base material on which the film is superposed, and

the casing has a drawing action section to apply tension to the film directly or indirectly.

2. The device according to claim 1, comprising an elastic member to come into contact with at least the surrounding portion of the input section, wherein

the drawing action section applies tension through the elastic member in a manner of drawing the film in a horizontal outward direction.

3. The device according to claim 1, wherein the drawing action section is an inclined plane, which is provided by forming in an integrated manner with the casing, so as to draw the film in a horizontal outward direction.

4. The device according to claim 1, wherein the drawing action section is a projection provided by forming in an integrated manner with the casing, so as to draw the film in a horizontal outward direction.

5. The device according to claim 2, wherein the elastic member comprises a projection, which comes into contact with the drawing action section.

6. An information input display device, comprising:

a display section to indicate information;

an input section arranged on a surface of the display section and capable of displaying the information in a transmittable manner;

a casing to contain the display section and the input section;

an elastic member to surrounds the entire side portion of the input section and the display section; and

a frame member to protect the surrounds of the display section and the input section through the elastic member and support the display section and the input section by connecting with the casing, wherein

the input section comprises a base material capable of displaying in a transmittable manner;

a film capable of displaying in a transmittable manner; and

an adhesives to adhere a surround portion of the film to the base material on which the film is superposed, and

the casing has a drawing action section to apply tension to the film directly or indirectly.

7. The device according to claim 6, wherein the drawing action section is an inclined plane provided by forming in an integrated manner with the casing, and causes a corner of the elastic member to come into contact with the film so as to draw the film in a horizontal outward direction.

8. The device according to claim 6, wherein the drawing action section is a projection provided by forming in an integrated manner with the casing, and causes of the elastic member to come into contact with the film so as to draw the film in a horizontal outward direction.

9. The device according to claim 6, wherein the frame member is arranged in that a supporting portion of the frame member has a height shorter than the thickness of display section and the input section, so that the frame member does not come into contact with the elastic member at least at a contacting surface of the casing.

10. The device according to claim 6, wherein the elastic member comprises a projection which comes into contact with the drawing action section.
