Abstract
The invention is a light guide coder structure, composed of a grating wheel made of photopermeability material, two mutually-vertical light emitting components and sensor, arranging a convex surface around the incident surface of the grating wheel, arranging the convex transparent part separated into equal arcs along the circle of the grating wheel, arranging a refraction space in the main body of the grating wheel, where the refraction space is able to guide the light primarily focused by the convex surface to the convex transparent part, making the light emitted by the light emitting component focused primarily by the convex surface and guided thought the refraction space to the corresponding convex transparent part for secondary focusing, and then transmitting the light to the sensor to generate different sequence phase signals, thus increasing tooth number of the grating wheel and simultaneously unable to influence the convenience in the preparing course.
Description
Technical field
The present invention relates to a kind of light conduct coder structure, refer to that especially a kind of increasing is located on the tooth number that grid are taken turns circumference, and the better light conduct coder of spotlight effect that makes light, simultaneously, can promote the convenience of its grid wheel when preparation process is produced.
Background technology
The main structure of general mouse, the X-axis and the Y-axis scrambler that comprise two groups of exportable sequential logic signals (as 11,10,00,01) utilize this mouse bottom surface to prop up desktop or other plane and move and make monitor desire the deal with data position to particular orientation and do relative displacement.With the principle of Data Position on this mouse mobile monitors is to utilize to operate X-axis and Y-axis scrambler simultaneously and produce moving of point on the plane basically.
See also Fig. 1, this scrambler generally by luminescence component 60, grid wheel 65 and sensor (its use two side by side sensitive chip S1, S2 to produce phase signal) 70 formed, during operation, because of making, the rotation of this grid wheel 65 is fixed on the not sensor 70 of homonymy of grid wheel 65 and luminescence component 60, and the light of luminescence component 60 covered or do not cover by grid wheel 65, makes sensor 70 produce the sequence signal of OFF (0) and ON (1) respectively.For example when grid wheel 65 rotated in a clockwise direction, the sequence signal that sensor 70 is produced was 111000011 ... continuous repeating signal, when rotating counterclockwise, then be 01001011010001 ... continuous repeating signal for the usefulness of circuit code.
Consult Fig. 2 A and Fig. 2 B again, this grid wheel 65 comprises the body 67 of a mechanical gear that removes square tooth 66 constructing, be the center of circle and be convexly equipped with a right cylinder 68 with cylindrical space with the center of this body 67 to the one side of body 67, on the plane of incidence of body 67, correspond to along circumference and be respectively equipped with a protruding grain 69 on the position of each square tooth 66, the ray cast of sending in order to luminescence component 60 can be with this light optically focused during to the plane of incidence of grid wheel 65, and with 671 refractions of the light behind the optically focused through space, a triangular-section, make light pass through the top of square tooth 66 and directive sensor 70, when this grid wheel 65 is subjected to rotating, the sensitive chip S1 of this sensor 70, S2 promptly can produce the sequence signal of OFF (0) and ON (1), for the usefulness of circuit code.
Above-mentioned grid are taken turns 65 structures, owing to will consider the quantity of the degree of depth, width and the protruding grain 69 of adjacent two square teeth 66, just can not cause this inconvenience of grid wheel 65 on preparation process is produced, these grid are taken turns 65 square tooth 66, protruding grain 69 numbers must be restricted so be located at, and can not arbitrarily increase.If can have one can make and be located on former grid and take turns the tooth number of 65 circumference and increase, and don't can influence it and on preparation process, perplex, must promote the convenience of this grid wheel 65 when producing.
Summary of the invention
One of the object of the invention is to provide one can increase the tooth number that is located on former grid wheel circumference, can not influence the light conduct coder structure of its convenience on preparation is produced again.
Another purpose of the present invention be to provide one optically focused of light is reflected again and secondary condensation to the light conduct coder structure of sensor.
For achieving the above object, the invention provides a kind of light conduct coder structure, be mutually vertical luminescence component with two and sensor is formed by grid wheels, be on the plane of incidence of this grid wheel, to be equipped with a projecting surface, the circumferential ring of grid wheel is provided with the convex part of arcuations such as being divided into, and grid wheel body is provided with one can be with the refraction space of the guiding of the light behind optically focused of projecting surface convex part; Optically focused of projecting surface that the light that this luminescence component sends is taken turns through these grid, and, be resent to sensor, to produce different sequence phase signals through reflecting steric direction to corresponding convex part secondary condensation.
That is to say, light conduct coder structure provided by the invention is to be equipped with a projecting surface on the plane of incidence of grid wheel, the circumferential ring of grid wheel is provided with the convex part of arcuations such as being divided into, grid wheel body is provided with one can be with the refraction space of the guiding of the light behind optically focused of projecting surface convex part, by this, can be in order to light through optically focused of projecting surface of this grid wheel, and through the refraction steric direction to corresponding convex part secondary condensation, be resent to sensor, to produce different sequence phase signals.
This grid wheel also comprises a discoid body, is the center of circle and is convexly equipped with one to the one side of body and has the right cylinder that is cylindrical space with the center of this body.
This refraction space is to be positioned at the cylindrical outside, and it is provided with several towards the beveled cone space that body is arranged with, and each beveled cone space has the inclined-plane that becomes the interface with body respectively, uses the light refraction behind optically focused to convex part.
