Claims

[Scope of utility model registration request]

A roll paper remaining amount detector that is composed of a plurality of sensors and outputs a detection signal to detect the remaining amount of the roll paper as it is consumed by printing, and outputs correction information based on the detection signal. a remaining amount detection circuit, a curl correction control unit that outputs a correction control signal that sets an amount to correct the curl of the roll paper based on the correction information, and a curl correction mechanism that corrects the curl of the roll paper based on the correction control signal. A roll paper feeding mechanism comprising: a paper ejecting mechanism section for cutting and ejecting the paper fed from the curl correction mechanism section;
