Touch panel assembly
First Claim
1. A touch panel assembly comprising:
- a spread illuminating device which comprises a light conductor plate made of a transparent material, and a rod-like lamp composed of a light conductor rod made of a transparent material and disposed close to and along at least one of end surfaces of the light conductor plate, and a point light source disposed adjacent to at least one of two ends of the light conductor rod, and in which light, that is emitted from the rod-like lamp, falls incident on the end surface of the light conductor plate and is introduced into the light conductor plate, exits out of the light conductor plate from its major surface toward a display portion of a liquid crystal display device;
characterized in that a housing frame to support components of the spread illuminating device in an integral manner is provided with a positioning mechanism for a touch panel, and a touch panel having no reinforcement member is fixed to the positioning mechanism.

Abstract
In a touch panel assembly, the thickness of a touch panel is successfully reduced by using a touch panel 10 provided with no reinforcement member. A housing frame 50 that supports the components of a front light unit 20 in an integral manner is provided with a touch panel positioning mechanism, and the touch panel 10 is fixed to the positioning mechanism, whereby the absence of a reinforcement member is duly compensated for, thus ensuring the strength of the touch panel 10. Deformation of the touch panel 10 that occurs when the touch panel 10 is pressed for operation can be attenuated by a transparent buffer member 5 disposed between the touch panel 10 and a light conductor plate 22. Therefore, the touch panel 10 deformed is prohibited from contacting and damaging the light conductor plate 22, thus preventing the light conductor plate 22 from deteriorating in its functional performance. Consequently, reduction in dimension and reduction of the number of components can be achieved without deteriorating the functional performance of the touch panel assembly.
