Abstract
The utility model relates to a bar code penlike scanner, comprising infrared light emitting diodes, a lens, a reflecting lens, an optical stop, and a printed circuit board for assembly the elements of photoelectric conversion circuit. The utility model has the technical proposal that the infrared light emitting diodes, the lens, the reflecting lens, the optical stop, and the printed circuit board for assembly the elements of the photoelectric conversion circuit are assembled inside a penlike casing in sequence. On the ground that a penlike structure adopts a penlike structure and a light source is the infrared light emitting diode, the utility model has small volume, simple structure, and convenient operation, and the utility model has functions for recognizing ordinary bar code symbols and hidden bar code symbols.
Description
The utility model relates to a kind of bar code pen type scanner that is used for the identification bar code symbol.
At present, the domestic barcode scanner that generally adopts is the slot type structure, this kind structure only is fit to detect the card of tape code mark, and detect extremely inconvenience for the bar code that is attached on the commodity, in addition, existing barcode scanner can only be discerned common bar code symbol, then is difficult to identification for the invisible-bar-number symbol.
In view of the foregoing, the purpose of this utility model provides a kind ofly can discern common bar code, can discern invisible-bar-number and pen type barcode scanner easy to use again.
The purpose of this utility model is achieved in that this scanner is assembled with infrarede emitting diode successively in a pen type housing, optical lens, catoptron, diaphragm, the printed wire of photodiode and assembling photoelectric switching circuit element, front port at the pen type housing is provided with a jewel ball, reduce force of sliding friction when being used to scan, at the infraluminescence pipe, optical lens, catoptron, diaphragm, in the optical system that photodiode is formed, light source adopts the infrarede emitting diode of peak wavelength 900nm to connect with integrated operational amplifier in the circuit board, carry out signal and amplify and shaping, output signal is connected by triple cable and five pin plug code translators.
The utility model is an infrarede emitting diode owing to having adopted pen type structure and light source, thereby not only volume is little, and is simple in structure, easy to use, and can have the function of common bar code symbol of identification and invisible-bar-number symbol simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
According to Fig. 1-2, describe concrete structure of the present utility model and operating process in detail.The pen type shell constitutes external form by nib 2, penholder 9, pen stand 10.Nib 2 and penholder 9 thread connection, penholder 9 and pen stand 10 screw attachment.Nib 2 front portions are stained with jewel ball 1.Infrarede emitting diode 3, optical lens 4, catoptron 5, diaphragm 6, photodiode 7, circuit board 8 are housed in the penholder 9.Be welded with cable 11 on the circuit board 8.Adopt this structure, behind written scan bar code symbol, the light signal that photoelectric switching circuit will react bar code symbol information converts electric signal to, and this signal is the millivolt order of magnitude, for satisfying singlechip CPU decoding requirement, has designed signal and has amplified and shaping circuit.Its circuit theory diagrams as shown in Figure 2, integrated operational amplifier U1 is amplified to the hundreds of millivolt with the signal of photodiode converts, 1/2U2 does the second level and amplifies, amplified signal is several volts, 1/2U2 compares shaping in addition, signal is output as Transistor-Transistor Logic level after the shaping.Output signal is connected with code translator through five pin plugs by triple cable.
Claims (2)
1, a kind of bar code pen type scanner, it comprises the printed-wiring board (PWB) of infrarede emitting diode, lens, catoptron, diaphragm and assembling photoelectric switching circuit element, it is characterized in that the printed-wiring board (PWB) of infrarede emitting diode, lens, catoptron, diaphragm and assembling photoelectric switching circuit element is assembled in the pen type housing successively.
