Abstract

PURPOSE: To make possible the high-speed recording of data in a high quality state using a compact ink jet printer by providing drive elements performing conduction control of electrothermal conversion elements sequentially in units of block, and sequentially driving every several blocks.
CONSTITUTION: Recorded data S1 consisting of the same number of bits as the number of electrothermal conversion elements is input synchronously to a clock signal CLK for recorded data transmission, then this recorded data is read into a latch circuit 5 in a drive IC 3 by a latch signal LAT. After that, the block of the electrothermal conversion elements which can be energized is shifted upon input of a signal EI for divided drive and a clock ECK for transferring a divided drive signal, and each block begins to be energized by the input of a signal ENB. The signal EI and the clock ECk are input at such a timing that every other group of the blocks is energized, that is, a power is turned ON to every other group of two blocks. Subsequently, the adjacent blocks are no longer driven continuously, so that a pressure variation is propagated to an adjoining ink path when the ink is discharged. Thus the irregularities in density nuance of a recorded image can be eliminated using a simple device.
