The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of anti-sticking paper apparatus of printer.
The utility model provides a kind of anti-sticking paper apparatus of printer; Comprise reflective photoelectric sensor, control module; Said control module is installed in the printer; Said reflective photoelectric sensor is installed in the paper delivery passage of printer, and said reflective photoelectric sensor links to each other with said control module; Said reflective photoelectric sensor is used to detect the whether gryposis of printing paper in the said paper delivery passage, and said control module is used to receive the signal of said reflective photoelectric sensor transmission and according to the print state of the signal controlling printer that receives.
As the further improvement of the utility model, said paper delivery passage is curved, and said paper delivery passage is formed by connecting beeline channel and angled channel, and said reflective photoelectric sensor is installed on said angled channel place.
As the further improvement of the utility model, this anti-sticking paper apparatus also comprises static electricity proof cover, and said static electricity proof cover is installed on the printhead of printer, and said reflective photoelectric sensor is installed on the said static electricity proof cover.
As the further improvement of the utility model, this anti-sticking paper apparatus also comprises baffle plate, and said paper delivery passage is made up of cover, static electricity proof cover and the said baffle plate of printer.
As the further improvement of the utility model, said paper delivery passage is shape linearly, and said paper delivery channel interior has a maximum arch paper position, and said reflective photoelectric sensor is installed on said maximum arch paper position.
The beneficial effect of the utility model is: detect the whether gryposis of printing paper in the paper delivery passage through reflective photoelectric sensor, and then the print state through control module control printer, printing paper gryposis state promptly occurs and then stop to print; Fault is got rid of, and then in time gets into the normal printing state when printing paper resets to normal condition naturally; Can effectively avoid the paper jam phenomenon of printer, guarantee the operate as normal of printer, increase work efficiency.
Description of drawings

Fig. 2 is first embodiment cross-sectional view of the utility model, the abnormality that occurs when wherein being obstructed for printing paper.
Fig. 3 is first embodiment cross-sectional view of the utility model, wherein stops up the extreme position state for printing paper.
Fig. 4 is second embodiment cross-sectional view of the utility model, wherein is the normal printing state during paperboard not.
Fig. 5 is second embodiment cross-sectional view of the utility model, the abnormality that occurs when wherein being obstructed for printing paper.
The specific embodiment
Extremely shown in Figure 3 like Fig. 1; The utility model discloses a kind of anti-sticking paper apparatus of printer; Comprise reflective photoelectric sensor 3, control module; Said control module is installed in the printer, and said reflective photoelectric sensor 3 is installed in the paper delivery passage 8 of printer, and said reflective photoelectric sensor 3 links to each other with said control module; Whether the printing paper 7 that said reflective photoelectric sensor 3 is used to detect in the said paper delivery passage 8 is crooked, and said control module is used to receive the signal of said reflective photoelectric sensor 3 transmission and according to the print state of the signal controlling printer that receives.
Reflective photoelectric sensor 3 detects the whether gryposis of printing paper 7 in the paper delivery passages 8, if not gryposis of printing paper 7, normal printing so; If printing paper 7 gryposis; Reflective photoelectric sensor 3 can detect barrier; Promptly detect printing paper 7; When reflective photoelectric sensor 3 detects printing paper 7, just prove printing paper 7 gryposis, reflective photoelectric sensor 3 transmitted to control module and stopped print signal this moment, and the control printer stopped to print after control module was received and stopped print signal; When reflective photoelectric sensor 3 did not detect printing paper 7, reflective photoelectric sensor 3 transmitted the normal printing signal to control module, and control module is controlled the printer normal printing after receiving the normal printing signal.Detect the whether gryposis of printing paper 7 in the paper delivery passages 8 through reflective photoelectric sensor 3; And then the print state through control module control printer; Can effectively avoid the paper jam phenomenon of printer, guarantee the operate as normal of printer, increase work efficiency.Said paper delivery passage 8 is under the situation that receives the external force interference, the printing paper 7 compelled bendings of being obstructed, and external force is removed, and promptly resets to normal condition naturally.
As first embodiment of the utility model, said paper delivery passage 8 is curved, and said paper delivery passage 8 is formed by connecting beeline channel 9 and angled channel 10, and said reflective photoelectric sensor 3 is installed on said angled channel 10 places.
Like Fig. 4 and shown in Figure 5, as second embodiment of the utility model, said paper delivery passage 8 is shape linearly, and there is a maximum arch paper position said paper delivery passage 8 inside, and said reflective photoelectric sensor 3 is installed on said maximum arch paper position.
This anti-sticking paper apparatus also comprises static electricity proof cover 6, and said static electricity proof cover 6 is installed on the printhead 5 of printer, and said reflective photoelectric sensor 3 is installed on the said static electricity proof cover 6.
This anti-sticking paper apparatus also comprises baffle plate 1, and said paper delivery passage 8 is made up of with said baffle plate 1 cover 2 of printer.
Described printing paper 7 gryposis of the utility model are meant when printing paper 7 receives extraneous resistance or paper jam phenomenon occurs, the phenomenon that printing paper 7 bends.Because paper delivery passage 8 might be an arc, printing paper 7 must have bending slightly in the motion process in the paper delivery passage 8 of arc, and this bending belongs to normal bending.That is to say through reflective photoelectric sensor 3 to detect under the situation of printing paper 7 that printing paper 7 all belongs to gryposis.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
