The structure of the instrument is composed of a shell and a movement, and the movement includes a paper folding mechanism, a paper speed reduction mechanism and a thermal printing mechanism. In order to facilitate the replacement of the recording paper, the paper folding mechanism is designed to be shaken out. When replacing the recording paper, press down on the positioning sheet and the folding mechanism will automatically pop out.
The setting operation keyboard is designed on the left and right of the display panel, so there is no need to remove the paper folding mechanism during on-site operation. The instrument adopts the current international popular galvanized sheet material and is processed by CNC equipment, which makes the instrument more beautiful and reliable.
