Patent ID: 7607468

Claim:
A tape printer comprising: a feeding device for pulling out and feeding a long roll sheet wound in a rolled state so that a back surface is outside, the roll sheet having encoder marks formed at predetermined pitch on the back surface, and comprising one of: a die cut label sheet having plural labels provisionally adhered to a front surface of a long release sheet arranged along the longitudinal direction of the release sheet, and an unfixed-length roll sheet formed by winding a long continuous printing medium; a printing device for printing on the roll sheet being fed by the feeding device; a mark detection sensor for detecting the encoder marks and issuing one of a plurality of output voltages unique to the detected encoder marks; sheet discrimination sensors for detecting the kind of the roll sheet; and a control circuit for controlling the feeding device on the basis of the one output voltage issued from the mark detection sensor, the control circuit including: an output voltage storage section storing the plurality of output voltages of the mark detection sensor corresponding to each combination of length of plural kinds of encoder marks in a feeding direction and a feeding speed of plural kinds of roll sheets; and a controller programmed to: determine the kind of the roll sheet detected by the sheet discrimination sensors; feed the label of the die cut label sheet to a print start position on the basis of the output voltage of the mark detection sensor in the case where the roll sheet is the die cut label sheet; and judge a feeding state of the unfixed-length roll sheet based on the one output voltage of the mark detection sensor in the case where the roll sheet is the unfixed-length roll sheet.
