PURPOSE:To obtain sharp recording generating no disturbance of printing by stabilizing the running of a recording medium and prevented from the detachment possibility of the recording medium during use, by providing a guide having a width equal to or more than the width dimension of the recording medium to the end part of the part relatively slid with the recording medium. CONSTITUTION:24 heat generation parts 2 are usually arranged to a head 1 in a line in the direction parallel to the feed direction X of recording paper. The single sides of heat generat ing layers 6 arranged so as to traverse the upper surface of the protective layer 5 provided on the straight line on a heat generating substrate 4 are connected to a common electrode 7 and the other sides thereof are connected to signal electrodes 8. The heat generating parts 2 selectively generate heat by the pulse signals from the signal electrodes 8 and the head 1 performs printing while moves to a direction Y and, when the head 1 reaches a right side predetermined position to complete the printing of one line, the head 1 is returned to the original left side predetermined position while recording paper is sent by one line in a direction X during the returning of the head 1. Notches are provided to both sides of a part, where an ink ribbon is contacted in a slidable manner, to form a guide 3. If the internal width dimension of the guide is set to x+alpha with respect to the width dimension (x) of the ink ribbon, the relation between alpha and (x) is desirably 0<=alpha<=2x and the depth dimension (y) is desirably set to 0.3mm or more. |
