Computer input unit and motion track perceptron thereof

Technical field

The utility model relates to a kind of computer input unit, relates in particular to a kind of computer input unit and motion track perceptron thereof of carrying out optical displacement sensing and button execution function.

Background technology

Along with development of science and technology and progress, no matter be personal computer (Personal Computer, PC) or mobile computer computer equipments such as (Notebook), become masses' indispensable portable tool in daily life or work, yet computer equipment must be by as pointer input devices such as mouse, Trackpad, trace balls, the controlling of the window interface of ability object computer equipment.

With the mouse is example, and its control mode roughly is divided into bobbin type mouse and optical mouse, to control the cursor position on the computer screen smoothly.The bobbin type MouseAcross is crossed the rotation of the spin that is installed in the bottom, so that detect the electron displacement signal that the grating wheel of change in displacement produces correspondence, and then the shift position of control cursor; Optical mouse projects light by the optical sensor module that is installed in the mouse bottom, and this light is learned in the optical sensor of induction module from an object surface refraction light echo, detecting variation, and then produce the cursor movable signal of a correspondence through the light of object surface refraction.

In addition, the TaiWan, China patent discloses a kind of optical pointer induction installation No. 592353, and it includes optical sensor module and printing opacity contact plate.The optical pointer induction installation presses the printing opacity contact plate by finger, and produces the optical sensor signal, advances the displacement start with controlling cursor.

The all types of mouse apparatus of above-mentioned prior art, its spin and optical sensor module only can be controlled the displacement start of computer cursor, click or relevant preset function as for execution, still must be dependent on a plurality of buttons (for example for commonly using the right and left key of mouse) of extra setting, push and carry out the pairing function of button for the user.

The mouse of prior art must dispose pointer induction module (for example being spin or optical sensor module) and operational and controlled key button, and mouse can be carried out start smoothly.Yet, in mouse inside pointer induction module and operational and controlled key button are set simultaneously, to make that the wiring of mouse inside is too complicated, cause the volume outward appearance of mouse too heavy, and can't slimming, and go up the wires design that must consider between each spare part in making, cause technique process relatively to increase, make peddling of computer input unit hold at high price, can't satisfy now the consumer must frivolous and cheap demand to electronic product.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of computer input unit and motion track perceptron thereof, pointer induction module and button so as to improvement prior art mouse apparatus, electrically be arranged at mouse inside respectively, make internal wiring be subjected to the restriction of pointer induction module and operational and controlled key button, cause in technology and the assembling too complicated, and the problem that the mouse volume can't slimming.

For achieving the above object, the disclosed computer input unit of the utility model includes housing and motion track perceptron, enclosure interior has an accommodation space, the motion track perceptron is movably set in the side in the housing, and has a circuit board, a displacement detecting unit and a microswitch.Wherein, the displacement detecting unit electrically is arranged at circuit board one side, and points the action of slippage by light source and optical sensor acquisition.Microswitch electrically is provided with the opposite side of circuit board with respect to the displacement detecting unit, and when pushing the motion track perceptron, microswitch is along with the displacement of motion track perceptron, and is resisted against housing, with the triggering for generating control signal.

And for achieving the above object, the present invention also provides a kind of motion track perceptron, is applied to a computer input unit, and this computer input unit has a processor, and this motion track perceptron includes: a circuit board; One displacement detecting unit electrically is arranged at first side of this circuit board, and this displacement detecting unit has a translucent element, and corresponding to a light source and an optical sensor of this translucent element, in order to the action of acquisition finger slippage; One microswitch electrically is arranged at second side of this circuit board with respect to this displacement detecting unit, produces a control signal; And an output port, electrically being arranged on this circuit board, and electrically connecting with this processor, the signal of exporting this displacement detecting unit or this microswitch is to this processor.

Effect of the present utility model is, by modular motion track perceptron, so that computer input unit can be carried out optical displacement sensing and key controlled function, its spare part is more simplified, manufacturing cost more reduces, and significantly promotes the assembleability of computer input unit.
