The printer transmission switching device that this utility model provides, when printer works, the paper feed drive motor formed by the first drive motor, paper feed gear train and corresponding paper feed pressure roller form paper feed drive mechanism, and the print drive motor formed by the first drive motor, print drive gear train and printing pressure roller form printing drive mechanism, paper feed drive mechanism and the printing separate synchronization that interdepends again of drive mechanism, controlling simple and clear, paper feed moves relatively reliable；And, paper feed drive mechanism and printing drive mechanism are provided separately, make to print drive mechanism paper feed in print procedure stablize and perform reliable, make paper feed drive mechanism realize multichannel simultaneously, thus realizing many spools paper feed and optional wherein some spool paper feed, the conveying of many paper rolls can be realized in printer, and the automatic switchover between each paper roll can be realized by arranging paper feed switching mechanism, meet different paper roll conveyings and print requirement；In addition, by arranging switching stroke sheet in paper feed switching mechanism, suppressing fixed structure, realize fixing when fixed structure ball is rocked to the detent switching stroke sheet when suppressing, ensure that switching puts in place and switches accurately, paper handoff procedure can be made precisely reliable, be less likely to occur switching not in place or switch excessive and after causing the situation of handoff failure to ensure switching simultaneously mechanism stable, location rocking handle will not be subject to swinging change gear and chart drive motor (the second drive motor) impact and producing skew.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics is absent from contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
