The specific embodiment

See also Fig. 3, Fig. 4, and Fig. 5 be respectively the utility model one preferred embodiment be mounted on black circle, when printing and be mounted on the position view of printer.The optical decoder device 10 of present embodiment includes: a housing 20, an optical transmission 30, an optical receiver 40, a bar code band 50, an and paster 60.Wherein, housing 20 includes room 21 in, a slotted eye 22, reaches a breach 23, and this breach 23 communicates with this slotted eye 22.

Optical transmission 30, and optical receiver 40 are interior rooms 21 that parallel and mutual correspondence is located in housing 20, and optical transmission 30, and optical receiver 40 and be positioned at the opposite side of the slotted eye 22 of housing 20, optical receiver 40 is in order to receive the optical signal that optical transmission 30 is transmitted.Bar code band 50 is vertically to be arranged between optical transmission 30 and the optical receiver 40 by slotted eye 22 in addition, and be positioned on the optical signal path that optical transmission 30 transmitted, bar code band 50 makes it have printing opacity and lighttight characteristic by the hole on it, covers or the optical signal that transmitted of shield light conveyer 30 not in order to selecting type.

In the present embodiment, optical decoder device 10 is to be mounted on the black circle 71 of a printer 70, and optical decoder device 10 is to slide also data to be printed on the printing paper 73 with black circle 71.Optical transmission 30 on the optical decoder device 10 is to be an optical diode, and optical receiver 40 then is a photistor.And because of optical transmission 30 and optical receiver 40 are in the parallel and mutual corresponding interior room 21 that is located in housing 20, so the transmission of optical signal, and receive very accurate.In addition, bar code band 50 is that the breach 23 via housing 20 vertically is arranged in the slotted eye 22, and bar code band 50 is positioned on the optical signal path that optical transmission 30 transmitted, so bar code band 50 covers or the position of the optical signal that transmitted of shield light conveyer 30 is very not accurate yet.

As shown in Figure 3, the breach 23 of the housing 20 of optical decoder device 10 is the bottom sides that are opened in housing 20, and paster 60 is then sticking to be located at the bottom side of housing 20 and to cover this breach 23.In the present embodiment, this paster 60 is to be a single face sticker sheet, directly sticking being located on the bottom side of this housing 20.

As shown in Figure 4, when printer 70 when printing, the ink droplet major part that is sprayed by the nozzle 72 of black circle 71 can be adhered on the printing paper 73, the ink droplet that fraction is not adhered to printing paper 73 then can form aerosol thing 74 near nozzle 72 floating, these aerosol things 74 are because of being subjected to stopping of paster 60, can't enter in the slotted eye 22 via the breach 23 of this housing 20, and then be attached on optical transmission 30 or optical receiver 40 elements.

By last explanation, the optical decoder device 10 of present embodiment has paster 60 because of the bottom side of housing 20, adhering to of aerosol thing 74 can be reduced significantly, so optical transmission 81 transmit optical signals, and the accuracy of optical receiver 82 receiving optical signals greatly improve, the optical decoder device of commonly using can reduce the probability of step level operation mistake significantly.

The foregoing description only is to give an example for convenience of description, and the interest field that the utility model is advocated should be as the criterion so that the claim scope is described certainly, but not only limits to the foregoing description.
