Technical Field
[0001] The utility model relates to a thermal printer, in particular to a thermal printer which can simply position a thermal sheet. Background Art
[0002] Thermal printers are a common printing device with many unique features and application scenarios. The working principle of a thermal printer is based on thermal technology. It heats the thermal print head to cause a chemical reaction in the coating on the thermal paper, thereby forming text, images and other content. Thermal printers have a fast printing speed and can quickly output printing results. They have a relatively simple structure, a small size, are easy to carry and install, and take up little space. Existing thermal printers generally have a card holder for rotating and connecting the thermal paper roll and a winding assembly for winding the thermal paper base. However, when the thermal paper passes through the thermal sheet, there is a lack of a structure for positioning and guiding the thermal paper, which may result in the width of the thermal paper being inconsistent with the card holder for rotating and connecting the thermal paper roll in the thermal printer and the winding assembly for winding the thermal paper base. The thermal paper may deviate when it is output, resulting in printing errors and inconvenient adaptation to thermal papers of different widths for printing. Utility Model Content
