Description
Technical Field
The utility model relates to a thermal printer field especially relates to a mechanism of quick change scroll of thermal printer in self-service equipment.
Background
Vertical self-service equipment is put in hospital hall, and the frequency of use is than higher, needs can accomplish daily maintenance fast, for example change the temperature sensing scroll. The required time is short, and the operation is very convenient. The original structure of the printer is that a plastic clamp spring is clamped on a paper shaft to prevent paper rolls from falling off. When the paper roll is replaced, the plastic clamp spring needs to be pried off the paper shaft by a tool to take out the old paper roll, and the plastic clamp spring is clamped on the paper shaft after a new paper roll is placed. This method requires a special tool, is time-consuming and inconvenient.
