Circuit board, for controlling motor 2, and detect leaf switch or microswitch 15 signal and infrared receiving tube 13 receive it is red
External signal.
The main realization process of the utility model printer engine includes：
（1）The separation of seat and anabolic process under the thermal printing head seat of honour and printer core.
As shown in figure 4, unitary hook is hooked with hanging hook assembly when closing, seat combines under the thermal printing head seat of honour and printer core
Together, being integrally formed structure detaches button and is not pressed at this time.
As shown in figure 3, being detached to the hanging hook assembly closed and unitary hook will be hooked, then need to press separation button, make
Side where button is detached in interlocking bar moves inwards, and the side being connected in interlocking bar with hanging hook assembly moves out, with band
The hanging hook assembly of dynamic interlocking bar opposite side leaves unitary hook.
（2）Lateral paperboard locator position fixing process.
Two lateral paperboard locators 14 can be according to the two the lateral paperboard positioning of the big minor adjustment of transverse width of label paper
Distance between device 14, to realize the located lateral of label paper.The two lateral paperboard locators can limit the laterally inclined of label paper
It moves, avoids the occurrence of the situation for making the position deviation of printing excessive due to lateral shift of the label paper in print procedure is excessive.
（3）Automatic reading label paper breaks realizes positioning and judgement number of labels process every position.
Label machine can use the double-deck printing paper being made of base's printing paper and label paper when printing, wherein, label
Paper cannot penetrate infrared light, and base's printing paper can penetrate infrared light.The disconnected of label paper only has one layer of base's printing paper every position.
Based on above theory, can the utility model can receive infrared according to the infrared receiving tube of seat under printer core
Light reads label paper automatically and breaks every position：In the disconnected at position of each label paper, infrared receiving tube can receive infrared light；
And in the other positions of label paper, infrared receiving tube cannot receive infrared light.And two the disconnected of label paper have 1 between position
Label paper is opened, therefore, can number of labels be judged every total number of positions amount by the disconnected of label paper.
It is that the preferable of the utility model is implemented to be illustrated, but the utility model is not limited to the reality above
Example is applied, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Shape or replacement, these equivalent deformations or replacement are all contained in the application claim limited range.
