Heat-sensitive recording apparatus

摘要

The heat-sensitive recording apparatus having a thermal head with heating elements arranged in one direction, a transport unit by which the thermal head and a heat-sensitive recording material being pressed by it are transported relative to each other in a direction normal to the one direction in which the heating elements are arranged and a drive unit that disperses image data for one pixel into a specified number of pieces and which drives the heating elements in the thermal head in accordance with the dispersed image data to perform heat-sensitive recording. The heat-sensitive recording by means of the drive unit satisfies T/n<=50 musec, where T is a period of recording the one pixel and n is the specified number of pieces into which the image data for one pixel is dispersed. The apparatus produces small enough recording sound to permit quiet heat-sensitive recording with the thermal head.
