Claims

[Claims for Utility Model Registration] A sub-chassis having a print head at the front end, a platen at the front end, and a roll paper accommodating section at the rear end is attached so as to be removable by a sliding mechanism, By placing the unrolled end of the roll paper stored in the paper storage section on the platen and pushing the sub-shear into the main chassis, the unwound end of the roll paper can be clamped between the print head and the platen. In the printer, the roll paper accommodating section has a rotary shaft on both sides, for fitting both ends of the rotary shaft attached to the center of the roll paper in a substantially horizontal state. A shaft introduction recess having a width slightly larger than the diameter is formed, and a semicircular arc shape having approximately the same curvature as the circumferential surface of the rotation shaft is formed at the lower end of the shaft introduction recess, and a lower half of the rotation shaft is formed. In response to this, a semicircular arc-shaped bearing part is provided in series to support the roll paper in a state that it is spaced apart from the bottom surface of the roll paper storage part, and the center part of the bearing part is set relative to the center part of the shaft introduction recess. A roll paper for a printer, which is eccentric to the platen side, and has a shaft holding part formed between the shaft introduction recess and the bearing part to suppress the upper peripheral surface of the rotating shaft on the platen side supported by the bearing part.
