Abstract

PURPOSE:To obtain a thermal printer which prevents a paper from staggering or skewing in a paper feeding and brings the paper into good contact with a thermal head, by providing a pinch roller in which the wall thickness of the center part of a rubber roller part is larger than that of the end parts thereof. CONSTITUTION:A platen is composed of a core bar 11 having a uniform diameter and a rubber roller part 12 which is provided around the core bar 11 so that the wall thickness of the center part is larger than that of the end parts; it is a rubber roller having approximately a barrel-shape. Therefore, the core bar 11 is deflected by being abutted by a thermal head 2, and the center part of the axis of the platen is more spaced from the surface of the thermal head than the end parts thereof. However, the large wall thickness of the rubber ensures a predetermined pressing force applied over the full length of the head and enables a uniform printing. Then, since the platen has a larger rotation radius in the center part than in the both ends parts, with the rotation of the platen a paper 3 is fed convergently. thereby being automatically corrected to a proper feed direction.
