Abstract

The invention provides a printer structure. When printing is performed, a roller applies a driving force on a thermal head and ensures the thermal head to move a certain distance backward, then an elastic device applies an opposite acting force on the thermal head to ensure that the thermal head closely sticks to the roller; and the flatness can be automatically adjusted through the opposite acting force of the elastic device. Therefore, the thermal head and the roller can be at the same level and the paper jamming phenomenon in the printing process can be avoided.

Description

【Technical field】 [0001] The invention relates to a printer structure, in particular to a printer structure used in medical equipment. 【Background technique】 [0002] Printers have been used in various fields, and they are also widely used in the field of medical equipment; for example, when people go to the hospital for physical examination, doctors need to use the printer on the medical equipment to print out waveforms for diagnosis and analysis, so as to judge the body of the examinee It can be seen that the application of printers in the medical field also plays an extremely important role, but the structure of printers currently used in the market has more serious paper jams during the printing process. 【Content of invention】 [0003] In order to solve the technical problem of printer jamming in the prior art, the invention provides a printer structure. [0004] The invention provides a printer structure, including a cover body, a roller, a limit device, a housing, a...
