ABSTRACT:
In a printing apparatus using a plurality of heating elements as printing elements, there are provided CCD elements for storing electric charges whose quantity correspond to temperatures in correspondence to each of the printing elements, and for sequentially transferring these electric charges. As a printing head driving apparatus, an analog shift register having a series of CCD elements is employed in order to perform data transfer operation, data alignment, and driving operations of the respective printing elements. Also, the above-described CCD elements are commonly used with CCD elements for storing and transferring temperature data. As a result, a compact printing apparatus can be made while suppressing shading in images caused by temperature increasing due to the driving operation of the printing elements.
