Description
Technical field
The utility model relates to barcode scanning device, especially a kind of code reader Laser emission receiving trap.
Background technology
Barcode scanner is also called bar code scan rifle or reader etc. by people usually, be for bar code reading comprise the equipment of information, one dimension, two-dimensional bar code scanner can be divided into.The structure of barcode scanner is generally following a few part: light source, receiving trap, photoelectric conversion part, decoding scheme, computer interface.The basic functional principle of scanner is: the light sent by light source is above irradiation optical system to bar code symbol.The light be reflected back on photoelectric commutator, is interpreted as through code translator the digital signal that computing machine can directly accept through optical system imaging.
At present, the barcode scanning job step that code reader common on the market adopts is: laser tube-condenser-reflective mirror-bar code, and then from the launching and receiving form of bar code-reflective mirror-condenser-receiving tube.In use, laser from laser tube emissions out after, will through multiple reflection, scanning and the reception work of bar code can be completed, in laser reflection transmittance process frequently like this, laser signal creates certain loss, simultaneously, can signal be received through multipath reflection, reduce the working sensitivity of code reader.As can be seen here, the Laser emission of existing code reader is large with the loss of reception ubiquity, the shortcoming that reaction velocity is slow.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, and laser scanning is highly sensitive, the code reader Laser emission receiving trap that laser reflection loss is few.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of code reader Laser emission receiving trap, comprise: circuit substrate, circuit substrate is provided with laser tube and receiving tube, it is characterized in that: be provided with pendulous device in described front, laser tube emissions direction, pendulous device is provided with reflective mirror, and this reflective mirror is corresponding with laser tube position; Between laser tube and reflective mirror, be also provided with condenser, this condenser is corresponding with reflective mirror and receiving tube position respectively; Condenser is provided with light hole, and the laser of laser tube emissions through light hole projection on a mirror.
Preferably, described condenser is concave mirror, is located at the middle part of condenser at light hole, the position of light hole just to laser tube, the laser making condenser can not block laser tube to send.
Preferably, side by side, the reflective mirror on pendulous device forms laser refraction by condenser and receiving tube for described receiving tube and pendulous device, by the laser projection that returns on receiving tube.
Preferably, described receiving tube is photoresistance.
After the utility model adopts said structure, on condenser, light hole is increased by adopting, the laser of laser tube emissions is directly projected reflective mirror from light hole, decrease the reflection of a laser, shorten working time and the length of laser, thus improve the barcode scanning sensitivity of code reader, reduce the loss of laser, guarantee the accuracy of data.The utility model structure is simple, and laser scanning is highly sensitive, and laser reflection loss is few.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, for achieving the above object, the technical scheme that the utility model adopts is: a kind of code reader Laser emission receiving trap, comprise: circuit substrate 1, circuit substrate 1 is provided with laser tube 2 and receiving tube 3, it is characterized in that: be provided with pendulous device 4 in described laser tube 2 transmit direction front, pendulous device 4 is provided with reflective mirror 5, and this reflective mirror 5 is corresponding with laser tube 2 position; Between laser tube 2 and reflective mirror 5, be also provided with condenser 6, this condenser 6 is corresponding with reflective mirror 5 and receiving tube 3 position respectively; Condenser 6 is provided with light hole 61, and the laser that laser tube 2 is launched is incident upon on reflective mirror 5 through light hole 61.
Preferably, described condenser 6 is concave mirror, is located at the middle part of condenser 6 at light hole 61, the position of light hole 61 just to laser tube 2, the laser making condenser 6 can not block laser tube 2 to send.
Preferably, side by side, the reflective mirror 5 on pendulous device 4 forms laser refraction by condenser 6 and receiving tube 3 for described receiving tube 3 and pendulous device 4, by the laser projection that returns on receiving tube 3.
Preferably, described receiving tube 3 is photoresistance.
Embodiment:
During barcode scanning work, the laser of barcode scanning sends from laser tube 2, laser is through the light hole 61 be arranged on laser tube 2 front condenser 6, project on the reflective mirror 5 on pendulous device 4, simultaneously, pendulous device 4 does reciprocally swinging, followed by the swing of pendulous device 4, laser is transformed into wire by point-like by reflective mirror 5, and projects on corresponding bar code simultaneously.Through the reflection of bar code to laser, laser with bar code information returns along former road, reflex to condenser 6 from reflective mirror 5, through the focusing of condenser 6 pairs of laser, improve the energy of laser, and make corresponding receiving tube 3 receive the laser returned, through digitized analysis, thus obtain the numerical information contained by bar code.
The above is preferred implementation of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
