Claims

[Scope of utility model registration request]

A roll paper cassette configured such that the roll paper pulled out from the supply reel is wound around a paper feed roller that also serves as a platen, and then wound onto a take-up reel;
A printer having an insertion section for the roll paper cassette, and having a print head facing the paper feed roller of the roll paper cassette inserted into the insertion section;
and a printing unit having a tension roller that comes into elastic contact with the paper feed roller and a drive mechanism that operates the paper feed roller, take-up reel, and printer, respectively; An opening/closing plate is attached to the inlet that is always supported by a spring to close the entrance. When this opening/closing plate is pressed open against the spring, the print head and tension roller of the printer are moved in conjunction with this. A cassette device for roll paper, characterized in that it is configured to operate away from the position of a paper feed roller.
