发明名称 COLOR INK JET RECORDING APPARATUS
摘要 PURPOSE:To express many hues and to constitute even a detailed image, by providing a counter capable of arbitrarily taking out a recording data signal indicating the variable density level of a pixel in synchronous relation to the generation of an ink jet particle. CONSTITUTION:A newly provided counter 27 outputs a signal requiring the output of a level signal to a level signal generating circuit 20' and a latch order signal latching said signal to a latch circuit 21 at each time when a predetermined number of pulses are inputted from a clock signal generating circuit 22. An address signal is successively outputted to a memory part 25 storing a threshold value in synchronous relation to the generation of ink jet particles and the threshold value stored in the address concerned is taken out to be inputted to a comparing circuit 26. Memory data indicating the variable density level of a pixel is taken out at the cycle set to the counter 27 synchronous to the generation of the ink jet particle to be inputted to the latch circuit 21 and compared with the aforementioned threshold value by the comparing circuit 26 and a dot recording signal is outputted corresponding to the comparing result.
