Title: Touch type mouse structure

Description:
BACKGROUND OF THE INVENTION  
      1.Field of the invention  
      The present invention relates to a touch type mouse structure, especially one using fingers to interrupt light and simultaneous press mouse function keys.  
      2. Description of the related art  
      Commonly used desktop mouse press control key structures are mechanically designed and some noise will be emitted when the keys are being operated. This kind of situation is quite disturbing, especially at night and since the noise sounds like the traditional typewriter, much improvement is therefore necessary.  
      The above-mentioned mechanical press control key structures and rollers are operated independently and some space need to be left beforehand for rebounding action and therefore, dust and other residues can easily smudge on.  
     SUMMARY OF THE INVENTION  
      The present invention relates to a touch type mouse structure mainly consisting of four pressing points matched with an inner sensor wherein the four pressing points forms a concave body, illuminating at the conducting bar of the concave edge. The bottom edge allows light to pass through for reaction of the inner sensor.  
      The present invention relates to a touch type mouse structure mainly consisting of four pressing points matched with an inner sensor wherein the sensor is surrounded by the conducting bar material on the outside and the light interrupting material on the inside. The sensor is designed at the center of each pressing point and connected to the build-in circuit of the mouse.

     DETAILED DESCRIPTION OF THE INVENTION  
      With reference to  FIG. 1  showing a plan of the commonly used mouse structure, a gap is left beforehand between the left control key  11  and right control key  12  of mouse  10  and the four rollers  13  are similar at every angle for convenient pressing and rolling. However, since this kind of structure is designed mechanically, some noise will be emitted while in use and the gap in-between the keys interface easily keep dust as well as other residue thus influencing work quality and proper mouse function. With further reference to  FIG. 2  showing a plan of the control principles of the present invention, when pressing point is being pressed by finger  20 , the sensor zone  22  of the concave body is being covered and light  23  interrupted.  
      With more reference to  FIG. 3  and  FIG. 4  showing a sectional view of the structure of the present invention and a plan of the sensor location, the structure of a pressing point  30  mainly consists of surrounding conducting bar  31  on the outside, interrupting light material  32  in the middle and light sensor  33 . The conducting bar  31  is slightly higher using the top convex edge  34  for light such that the interrupting material  32  cannot cover light from the top edge for reaction of the light sensor  33  found at the center of the bottom edge  35 . The control key interface is designed in a round concave shape body for convenient touching and covering and a pass-through light layer  36  added for special dust and water-proof function.  
      With further reference to  FIG. 4 , the sensor  33  is placed according to the location of function keys such as left key light sensor  331 , right key light sensor  332 , upper roller key sensor  333  and down roller key sensor  334  as shown in the diagram. The top edge is used to respond to light interruption of the light sensing zone and the other edge is directly connected to the inner circuit of the mouse. In addition, if music lovers cannot adapt to the soundless effect, a software can easily resolve such a problem and different touching keys can emit different kinds of animals&#39; sounds. Hence, the present invention provides a very modernized mouse structure using the finger to touch function keys and interrupt light for silent effect. The key table is also designed with a pass-through light layer such that there are no gaps in-between the keys to avoid dust and other residues.
