Title: Heat-sensitive recorder
Inventor: NAKAMURA KOUZOU
IPC: B41J2/36
Filed: 1982-05-07
Abstract: PURPOSE:To realize the heat-sensitive recording having gradation with a simple circuit constitution, by carrying out plural times the electric conduction control of a prescribed time to each heating register with variation of the threshold level to a prescribed recording picture element. CONSTITUTION:An analog picture signal S is converted into a binary gradation information signal by an A/D converter 1 and then stored in a line memory 2. A threshold level generation counter 12 varies the level of a threshold signal D every time the electric condution control is executed for a prescribed time to a prescribed heating resistor. A digital comparator 13 compares a gradation information signal C read out of the memory 2 with the signal D. The output signal E of the comparator 13 is set at level H and at level L when the level of the signal C is higher than that of the signal D and vice versa. A shift register 14 gives a series-parallel conversion to the signal E and supplies it to a recording head 3 via a latch circuit 15 and a signal switch 8. The circuit 15 holds the block address delivered from a block counter 5 for plural times of conduction control of a fixed time.
