Abstract:
1. A control circuit of a multiplexing inkjet print system, for driving at least one heater circuit, comprising: a signal generating unit, for generating an enable signal according to a first clock signal and a data; a shift register, electrically connected to the signal generating unit, for shifting the data according to the enable signal and a second clock signal, so as to generate i address signals, wherein i is a positive integer; a counter, electrically connected to the signal generating unit, for counting according to the enable signal, so as to generate a plurality of time counting signals; and N decoders, electrically connected to the counter, for respectively receiving a portion of the time counting signals, wherein each of the decoders is used to decode the received time counting signals to generate a plurality of start signals, and N is a positive integer equal to or greater than 2; wherein the drive control of the heater circuit is achieved through the address signals and N groups of the start signals.
