Abstract

PURPOSE:To eliminate a contact with a cutter and thereby prevent generation of a paper jam by providing a printing head, with a flat tip, formed suitable to press printing paper against a platen, and placing the head in the center of printing paper, if the feed volume of printing paper is counted and the count indicates that the volume stays within a specified range. CONSTITUTION:Printing paper 3 is placed on a tractor wheel 4, then a stepping motor 9 is driven by pressing a switch on a control panel, and the printing paper 3 is transported. After this, the top of the paper is detected by a printing paper detection sensor 12 and a specified volume of paper is transported. In this case, a carrier 7 is moved to the center of the paper by the driving of the stepping motor 11 at the same time as the switch on the control panel is pressed. Consequently, the paper 3 is pressed by a ribbon guide 6, so that the paper can be held only by a carrier operation control system without using a complex mechanism. Thus it is possible to reduce the number of mechanism parts and transport the paper reliably.
