ABSTRACT:
A plurality of thermal heads each having a resistance heating element array are provided for a single platen roller. The individual thermal heads are arranged away from one another in the axial direction of the platen roller in such a way that regions in which images are recorded by their respective heating element arrays overlap each other at the joint portion of said regions. The thermal heads are also spaced away from one another in the circumferential direction of the platen roller so as to avoid mutual interference. The above arrangement makes it possible to use only a single platen roller for a recording apparatus which performs recording in a large recording area, thus contributing to making the apparatus compact.
