Description

Optical mouse and optical devices thereof

Technical field

The utility model relates to a kind of optical mouse and optical devices thereof, and wherein optical mouse provides the optical devices of two groups of different sensing light sources, and optical mouse can be worked on various surface.

Background technology

Formerly in the optical mouse technology field of technology, its principle mainly is to use a light supply apparatus (as light emitting diode) to project an incident light to desktop or mouse pad, and judge that by the reflected light that on using planar, produced of acquisition the inhomogeneous or nick that its surface has is protruding, with the action situation of control optical mouse.

Please refer to disclosed prior art in No. the 504638th, the TaiWan, China patent announcement, see also Fig. 1, is the partial exploded view of the optical devices in the existing optical mouse.The optical devices of existing optical mouse, it comprises a drain pan 1a, it has an opening 10a; One leaded light component 2a is contained on the opening 10a of drain pan 1a, and leaded light component 2a includes an eyeglass 20a, one first reflecting surface 22a and one second reflecting surface 24a; One circuit board 3a is located on the leaded light component 2a.Circuit board 3a has a hole 30a, be positioned at eyeglass 20a top, and an optical sensor 4a just is contained in the top of circuit board 3a hole 30a.Optical sensor 4a can obtain the image that optical mouse slips over the plane, and analyzes the obtained picture of optical sensor 4a with circuit (figure slightly), therefore determines the displacement of optical mouse.One light emitting diode 5a also is contained on the circuit board 3a.Light emitting diode 5a is intended for the light source of optical sensor 4a, because outside the first reflecting surface 22a outburst hole 30a, make and win reflecting surface 22a just between light emitting diode 5a and optical sensor 4a, at last, one light shield 6a also is contained on the circuit board 3a, and the light that is used for avoiding light emitting diode 5a to be sent is directly injected optical sensor 4a.

Seeing also Fig. 2, is the cut-open view of the optical devices among Fig. 1.Light 11a is emitted by light emitting diode 5a, though light shield 6a has interdicted the sub-fraction of light 11a, but the direction direct projection that most light 11a can face towards light emitting diode 5a and going out, since the direction that light emitting diode 5a faces is exactly the first reflecting surface 22a, so most light 11a can penetrate towards the first reflecting surface 22a, and reflex to the second reflecting surface 24a downwards by the first reflecting surface 22a, reflection through the second reflecting surface 24a, light 11a can pass the opening 10a of drain pan 1a, and illuminates plane 13a.The light 11a that is incident in plane 13a can be become reflection ray 12a by the character of surface modulation of plane 13a and reflection.Next reflection ray 12a can be collected by eyeglass 20a and focus on the optical sensor 4a, and optical sensor 4a utilizes reflection ray 12a to obtain the picture of plane 13a continuously, and analyzes these continuous pictures, with direction and the distance that determines that optical mouse moves.

After the light signal of aforementioned light emitting diode 5a is radial sending, must just can be passed to optical sensor 4a, so light signal can loss in transmittance process through the first reflecting surface 22a, the second reflecting surface 24a and eyeglass 20a.In other words, the light signal that sent of light emitting diode 5a can't be passed to optical sensor 4a fully.When a little less than the light signal, the sensitivity of optical sensor 4a and resolution can reduce, and then influence the performance of optical mouse.

In addition, when traditional optical mouse is used on smooth surface, can quite have some setbacks usually, the optical image of the computing machine that sends to chases after vertical, and can't the accurate localization mouse moving.

Be with, above-mentioned traditional optical mouse still exists shortcoming to be solved and improves part.

Therefore, the inventor is according to abundant for many years practice experience, concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively solve the utility model of the shortcoming of prior art finally.
