New description: [New technical field] The present invention relates to a light guiding structure for a button with a backlight source; in particular, a light guiding layer is disposed between the rubber pad layer and the button portion, The light source can be passed over the rubber mat layer to produce a more desirable retroreflective effect and reduce the likelihood of forming a black film on the button portion. [Prior Art] • * Electronic objects using a keyboard (such as a computer, mobile phone, computer...) = a turtle board is provided, and a printed circuit board is provided with a response to the keyboard tapping or pressing. The rubber layer; the rubber layer has a plurality of elastic support portions and guide points in the support portion, and the guide contacts can form an f-gas connection with the printed circuit board via the off-four (4) when the keyboard is not hit. In order to provide a backlight or illuminating slit that can be exposed to low light levels at night or in the surroundings, it is a well-known technique. For example, 'Taiwan No. 2458 "backlit button", No. 94107422 "Backlight type, key assembly", and No. 94316321 "Backlight type" patent case, etc., etc., provide a typical example. In order to obtain the effect of the brightness average sentence, they usually provide more than one light source under each button of the key, or because the number of light sources is more, so the cost is higher, the circuit design configuration is complicated, the energy consumption is higher, etc. Feelings are usually not compared to Wei's computer keyboard with a large face. • μ Xizhi County has also revealed the concept of means around the light source or light guide to guide the light source. For example, Taiwan No. 94137063 "Plate with Backlight Architecture", No. 94107422 "Backlight Type In the patent case, etc., a typical embodiment is respectively mentioned. In the case of the "Backlight Button Assembly" No. _7422, it is revealed that at the interval between each adjacent button or at the position around each button, 7 is placed with a view material. The light guiding element reads the light emitted from the light emitting element disposed under the button 5 M352119, and is led out from the periphery of the button. The above-mentioned No. 94137063 "has a back-to-back plus--a relatively complicated backlight structure, and it is a combination of the bridges, the boundary (10) - the light source conduction = and the second supply of the linkage The position of the side light guide is approximately in the position close to the periphery of the button. The light is directed to the direction of the button to form the backlight of the disk.

Therefore, in the embodiment taken, the button portion 40 is disposed on the upper surface of the light guiding layer 30, and is preferably made of two materials. Referring to Fig. 3, it is specifically noted that the light emitted from the light source 32 is guided to the button portion 4 through the reflective surface 33 of the light guiding layer 3; the third figure also shows the slope of the hole 34 = also the light source 32 The light beam is reflected upward to the button portion 40' so that the moonlight effect of the button portion 4〇 is better than the conventional structure. It will be appreciated that in a modified embodiment the angle of inclination of the bevel 35 of the aperture 34 can be varied. In another possible embodiment, the bottom surface of the light guiding layer 30 is a structure capable of forming reflective bumps, which helps to increase the light reflecting effect of the light guiding layer 30. Typically, the button light guiding structure provides the following design considerations under the condition of providing a structural simplification: L. In order to consider the ideal reflective or light guiding effect, the above-mentioned base layer 1 橡胶, rubber cushion penalty, The arrangement position or order of the light guiding layer 30 and the button portion 40 is specially designed and modified; when the light guiding layer 30 is disposed on the upper surface of the rubber mat layer 20 and below the button portion 4〇, the light guided by the light guiding layer 30 It can smoothly pass over the elastic support portion 22 of the rubber mat 20, so that most of the light source 32 or light is directly directed to the button portion, as in the case of forming a black film or black shadow on the button in the old method, as much as possible It is reduced to a minimum.
