Abstract

An image recording apparatus which performs time division and driving of 128 recording devices arrayed within an LED chip includes shift registers for sequentially serially outputting 128 bits of continuous pixel data to 56 signal lines, corresponding to each LED, from one line of serially input pixel data row, selectors which perform time division of the 56 pieces of pixel data into 8 times of 7 pieces apiece and then outputs the data, and registers which hold the pixel data output from the selectors for each corresponding LED chip. The image recording apparatus may be used as a recording head for a printer using solid recording devices is simplified, and costs are reduced.
