Abstract
The utility model relates to a photoelectric sensing device. The utility model comprises an outer shell, a light source part which is mounted in the outer shell for the transmission of the photoelectric information, a sensor module which is used to receive the photoelectric information, a PCB board which is connected with the sensor module and a lens which is used for light guidance. An optical gap for the transmission of the light which is reflected by a finger is mounted on the outer shell. As the photoelectric sensing device of the utility model is fixed and the reference plane (the finger) moves correspondingly relative to the photoelectric sensing device, the photoelectric sensing device senses the movement of the reference plane and calculates the corresponding displacement information. And the resolution of the photoelectric sensing device of the utility model reaches 3000CPI, therefore, when the center of the finger aligns to the center of the sensor, only one time movement of the finger can cover the whole screen. Simultaneously, when the photoelectric sensing device of the utility model is mounted on a notebook computer, a PDA or a remoter control, the equipments can be produced thinner due to the lack of one layer of touch screen.
Description
Technical field
The utility model relates to photoelectric sensing apparatus, more particularly, relates to a kind of photoelectric sensing apparatus that is used on the products such as notebook computer, palm PC.
Background technology
Former notebook computer adopts a touch pad of bottom to realize the cursor of mouse, for consumer electronics, and handheld device especially, the integrating mouse cursor device, difficult to realize.And traditional optical mouse is to rely on mouse to move in the position of reference surface to realize moving of cursor of mouse.Present PDA, smart mobile phone all uses touch-screen to carry out the location of cursor, and the displacement of hand is very big, and cost is also high, but also across one deck touch-screen.Digital TV set-top box for another example, it is very inconvenient to be used for online, does not have cursor on the telepilot, need be with directionkeys by more than once.Traditional optical mouse is to rely on mouse to move in the position of reference surface to realize moving of cursor of mouse, and this is for PDA, smart mobile phone, and application scenarios such as telepilot are difficult to provide the bigger reference planes for the mouse use.
The utility model content
The technical problems to be solved in the utility model is, the defective at the above-mentioned moving cursor inconvenience of prior art provides a kind of photoelectric sensing apparatus.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of photoelectric sensing apparatus, comprise shell, be arranged on the light source portion that being used in the described shell sends optoelectronic information, be used to receive optoelectronic information sensor assembly, with the pcb board that described sensor assembly links to each other, also be provided with on the described shell and be used to the light slit mouth that appears light and reflect back by the human body contact site.
In photoelectric sensing apparatus described in the utility model, be used for light slit mouth that the light emission that described light source portion is sent is gone out, described light slit mouth is circular.
In photoelectric sensing apparatus described in the utility model, the diameter of described light slit mouth is less than 4 millimeters.
In photoelectric sensing apparatus described in the utility model, described light slit mouth opening be arranged on the user and point the contact position, described shell also is provided with the finger position at described light slit mouth place.
In photoelectric sensing apparatus described in the utility model, described light source portion, sensor assembly are structure as a whole.
In photoelectric sensing apparatus described in the utility model, the resolution of described sensor assembly is greater than 3000CPI (Count Per Inch, per inch 3000 points).
In photoelectric sensing apparatus described in the utility model, described light source portion is LED, laser beam emitting device.
Implement photoelectric sensing apparatus of the present utility model, have following beneficial effect: when being arranged on the equipment such as notebook computer, PDA, telepilot owing to photoelectric sensing apparatus of the present utility model, because lacked one deck touch-screen, equipment can be done thinlyyer.
Photoelectric sensing apparatus of the present utility model is fixed itself, and reference surface (finger) relatively photoelectric sensing apparatus is done corresponding mobile, the moving of photoelectric sensing apparatus sensing reference face, and calculate corresponding cursor displacement information.And the resolution of the sensing equipment that the utility model adopts has reached 3000CPI, when finger centrally aligned center sensor, only need move once finger and just can cover whole screen like this.When being arranged on the equipment such as notebook computer, PDA, telepilot owing to photoelectric sensing apparatus of the present utility model simultaneously, because lacked one deck touch-screen, equipment can be done thinlyyer.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the cross-sectional view of photoelectric sensing apparatus of the present utility model.
Embodiment
The structure of photoelectric sensing apparatus of the present utility model is described in conjunction with Fig. 1, photoelectric sensing apparatus structure of the present utility model is as follows, comprise shell 4, be arranged on the light source portion in the described shell 4, be used to send the light source portion of optoelectronic information, be used to receive optoelectronic information sensor assembly 3, with the pcb board 2 that described sensor assembly 3 links to each other, also be provided with light slit mouth 1 on the described shell 4, light slit mouth 1 is used to appear light and reflects back by finger again.Wherein light slit mouth 1 can be circle.1 diameter of light slit mouth is 3.5 millimeters, and for the convenience of the users, shell 4 is provided with the finger position of depression in user's contact position.Light source portion, sensor assembly 3 are structure as a whole in the present embodiment.Certainly light source portion, sensor assembly 3 etc. also can divide and are arranged.
The resolution of sensor assembly 3 is greater than 3000CPI.Photoelectric sensing apparatus of the present utility model can be arranged on the equipment such as notebook computer, PDA.Use this device on PDA, equipment can be done thinner, because lacked one deck touch-screen.And if CPI reaches 3000CPI, the finger area calculates according to 10mm x10mm, work as the user like this finger centrally aligned center sensor, finger displacement is when being 5mm, and corresponding sensor 600 points that can count are coordinate like this with the screen center, can count up and down each 600, the displacement of a finger just can produce the distance of 1200x 1200, and enough pointers location has been used.The positional information that photoelectric sensing apparatus produced, only needs process software carries out the simple process on the left and right, up and down direction, uses just can for notebook computer, PDA equipment.
Photoelectric sensing apparatus of the present utility model also can be with on the telepilot at home, digital TV set-top box for example, and it is very inconvenient to be used for online, because there is not cursor, need be with directionkeys by more than once.Be provided with photoelectric sensing apparatus of the present utility model just can be hand held in, carried out cursor positioning.
