Embodiment
See also Fig. 3, the device for locating optical pointer 100 of present embodiment mainly includes a housing 110, an elasticity light-passing board 120, one movable refractile body 130, one movable inductor 140, a light source 150, an actuator 160, a first circuit board 170, a second circuit board 180, two elastic partss 190 and a condenser lens 195.
As shown in Figure 3, housing 110 has an opening 111.Elasticity light-passing board 120 is to be connected in housing 110, and covers opening 111.
Movable refractile body 130 is to be arranged among the housing 110, and is to be positioned under the elasticity light-passing board 120.More detailed, movable refractile body 130 is to be connected in first circuit board 170, moves up and down so movable refractile body 130 can be done among housing 110.
As mentioned above, device for locating optical pointer 100 can be arranged in pairs or groups and is applied on the device such as computing machine, telepilot, mobile phone and PDA, and cursor on its screen moves and function clicks to carry out.When user's thumb (object) T is displaced on the elasticity light-passing board 120 of device for locating optical pointer 100, the light that light source 150 sent can be passed to elasticity light-passing board 120 via the refraction of movable refractile body 130 earlier, the thumb T image that will be positioned at then on the elasticity light-passing board 120 reflexes to movable inductor 140, and is received by movable inductor 140.Then, movable inductor 140 can change moving direction and the distance of judging thumb T according to the reflected image of thumb T, and the signal-arm of output correspondence moves to carry out cursor corresponding on its screen to computing machine, telepilot, mobile phone or PDA.Then, when cursor arrives location and user's desire execution point selection function on screen, the user can directly press compression elasticity light-passing board 120 with thumb T, at this moment, the elasticity light-passing board 120 that is connected in housing 110 can produce elastic deformation, and forcing the movable refractile body 130 and the movable inductor 140 that are connected in first circuit board 170 to move down, elastic parts 190 then can be compressed.At last, the movable inductor 140 that moves down can be pressed and be contacted actuator 160, and actuator 160 just can be exported the actuated signal of a correspondence to computing machine, telepilot, mobile phone or PDA, to carry out a selection operation.On the other hand, after a selection operation is finished, the user only need unclamp thumb T a little, and at this moment, first circuit board 170, movable refractile body 130 and movable inductor 140 just can be moved upward to its original position because of the elastic-restoring force that elastic parts 190 is provided.
In sum, device for locating optical pointer of the present invention can have easy-to-use advantage, and can avoid the mistake induction of movable inductor to take place.Moreover device for locating optical pointer of the present invention can be save the setting of button, thus can simplify the complicacy in the manufacturing, thereby can reduce its manufacturing cost.In addition, the profile of device for locating optical pointer of the present invention can meet the demand of ergonomics and do any variation.
Above-mentioned embodiment is only in order to explanation the present invention, but not in order to limit the present invention.
