Abstract
A protective sheet protects a recording surface of a recording sheet. Plural recording sheets are stacked with the recording surface of the recording sheets oriented toward the protective sheet. The recording sheet is fed for recording while an advancing edge of the recording sheet is advanced. The protective sheet includes a discriminative mark, disposed away from the advancing edge and on a surface oriented opposite to the plural recording sheets for signaling presence of the protective sheet. For use with those sheets, a printer records with a thermal head on a recording surface of a recording sheet set on a platen drum in rotation of the platen drum. The advancing edge is clamped by a clamper on the platen drum. The recording sheets and the protective sheet are fed one after another toward the platen drum, to pass the advancing edge of the one fed sheet inside the clamper. The advancing edge at the clamper is detected by the position sensor. The one fed sheet is mounted on the platen drum while rotating the platen drum after the clamper clamps the advancing edge. Presence of the discriminative mark is detected on the one fed sheet on the platen drum. If the discriminative mark is detected, the one fed sheet is judged as the protective sheet, to exit at least the protective sheet from the platen drum.
