Abstract
A thermal transfer printer containing a means for feeding a plurality of thermal transfer sheets and a plurality of image receiving sheets, a platen roller placed in the feeding path of the thermal transfer and image receiving sheets, and a recording section with a thermal head with a plurality of heating resistors for selective activation based upon image data to record the image on the image receiving sheets when they and the thermal transfer sheets are forced together by the platen roller so each image receiving sheet is pressed on the thermal head surface by the platen roller. The recording section also has a means to detect when at least one of the thermal transfer and image receiving sheets being recorded are out and a means automatically to exchange the thermal transfer or image receiving sheets with new sheets based upon the detected result.
