Benefits of technology

[0007]The present invention is to provide a light guiding plate and a keystroke module for use therewith; during the pressing operation of the fingers, it is uneasy for the surface of the light guiding plate to generate quick wearing; in the meanwh

Problems solved by technology

However, in the keystroke module of the prior arts, following drawbacks are still existent under practical application: first of all, since its light guiding plate is a hard plate body, so it is easy for each component contacted with the light guiding plate to generate wearing damage under the pressing operation of longtime and high frequency, besides the touching feeling of keystroke being very poor; second, a spring membrane, having plural metallic springs, is usually arranged under the light guiding plate, and its surface easily generates plastic deformation, after being

Embodiment Construction

[0017]In cooperation with attached drawings, the technical contents and detailed description of the present invention will be as follows.

[0018]Please refer to FIG. 1 through FIG. 3, which separately are a respective explosion view of the light guiding plate and an assembling illustration of the keystroke module according to the present invention, and partial enlargement view of the A area indicated in FIG. 2. The present invention is to provide a light guiding plate and a keystroke module for use therewith, the keystroke module mainly comprising a contacting and controlling layer 10, a light guiding plate 20, and a light source 30, wherein:

[0019]The contacting and controlling layer 10 is made of the material of polycarbonate (PC) and has a pressing side 11 and a contacting and light guiding side 12 formed under the pressing side 11. In this embodiment, plural protrusive key buttons 13 are formed at intervals on the pressing side. Corresponding to the center of each key button 13, a con

Abstract

A keystroke module for use with a light guiding plate includes a contacting and controlling layer, a light guiding plate and a light source. The contacting and controlling layer has a pressing side and a contacting and light guiding side. The light guiding plate is arranged under the contacting and light guiding side of the contacting and controlling layer and further includes a light auxiliary layer and a light inducting layer, which is a soft piece body having a reflecting side, on which plural light guiding parts are arranged, while the auxiliary light layer is a hard transparent piece body that is laminated correspondingly above the reflecting side of the light inducting layer. In addition, the light source is arranged at one side of the light guiding plate for irradiating light from the light auxiliary layer, then the light being reflected out by the reflecting side and the light guiding parts of the light inducting layer; thereby, it is possible to prevent the components contacted with the light inducting layer of the light guiding plate from easy wearing and permanent deforming, and the using lifetime of the light guiding plate or the keystroke module may be prolonged significantly.
