The operation principle of printer of the present utility model and feeder embodiment thereof roughly comprises:
paper feeding process under normal operating conditions, referring to Fig. 5, printing paper 100 is through printhead, after cutting knife is processed, by lateral paper guide 4 and paper guide block 2, successfully enter into paper feed port, first sensor 3 has been sensed printing paper 100 and has been existed, send instruction to motor 12 via controller (scheming not shown) immediately, motor 12 starts, power train 13 entrys into service, order about driving wheel 11 forwards, pinch roller 6 reverses under the drive of driving wheel 11, when printing paper 100 touches driving wheel 11 with pinch roller 6, under the effect of the frictional force between printing paper 100 and driving wheel 11 and pinch roller 6, printing paper 100 is carried to the exit slot direction.
exist artificial or have barrier to block the paper feeding process of exit slot, referring to Fig. 6, at this moment motor 12 can not quit work, print procedure is still continuing, this moment is under the effect of the lower protuberance 42 of lateral paper guide 4, printing paper 100 has the trend of distortion downwards, continue to block exit slot, the deformation tendency of printing paper 100 as shown in phantom in Figure 6 so, hold the storage area that paper chamber 15 has become the printing paper 100 in a print procedure, after exit slot place's barrier eliminating, motor 12 works on regular time (time of software set), until printing paper 100 is sent fully, going out paper sensor (scheming not shown) signal this moment changes, motor 12 quits work, can enter next time and print.
the paper feeding process that printing paper 100 is not in time taken away, referring to Fig. 7, if within the time of setting, printing paper 100 does not have removed, this moment, the second sensor 9 also detected printing paper 100, motor 12 begins counter-rotating, driving wheel 11 counter-rotatings, drive lower pressure wheel 6 forwards at driving wheel 11, when printing paper 100 touches both, under the effect of printing paper 100 and frictional force (frictional force is regulated by shell fragment) between the two, printing paper 100 withdraws from along moving back the paper road, when the second sensor 9 detects when not having paper, motor 12 quits work, printer can be printed next time.
Compared with prior art, printer of the present utility model and feeder thereof, lateral paper guide 4, the paper guide block 2 that cooperatively interacts by setting, lead paper support 8, first sensor 3 and the second sensor 9, can guarantee that printer is not having removed and/or exit slot in particular cases yet can work stopping up such as paper delivery.
Need to prove, in the present embodiment, the second sensor 9 is can work to move back paper to detect in moving back the paper process, and plays paper delivery and detect in the paper delivery process.In other embodiment, two sensors also can be set, one be specifically designed to the paper situation of moving back that detects, another is specifically designed to the paper delivery situation that detects.
Above, be only the preferred embodiment of the utility model, be intended to further illustrate the utility model, but not it is limited.All simple replacements of carrying out according to above-mentioned word and the disclosed content of accompanying drawing are all at the row of the rights protection scope of this patent.
