Abstract:
A recording head circuit is configured to drive a plurality of recording elements by dividing the plurality of recording elements into a plurality of blocks. The circuit delays not only heat signals, which are used to drive the recording elements in each of the blocks, but also block signals. Consequently, noises are prevented from appearing due to overlapping of signals.
