Abstract:
An information recording apparatus comprising:a recording head for recording a line of recording information on a recording medium, said recording head having a plurality of adjacent heat energy generating elements corresponding to a plurality of ejection portions for ejecting ink to record the line of recording information and a common ink supply chamber for supplying ink to the plurality of ejection portions, wherein each said heat energy generating element heats the ink in response to a drive signal, thereby ejecting ink droplets from a corresponding said ejection portion and attaching the ink droplets to the recording medium;information inputting means for inputting a line of recording information to be recorded by said recording head;information storing means connected to said information inputting means for storing the line of recording information input by said information inputting means; anddrive means for driving said heat energy generating elements, wherein said drive means is connected to said recording head and to said information storing means for applying to each of said heat energy generating elements a corresponding drive signal in accordance with the line of recording information stored in said information storing means; anda time-division driving circuit for providing to said drive means plural selection signals that permit said drive means to apply a drive signal to a corresponding said heat generating element, wherein during recording of the line of recording information the selection signals permit application of a drive signal to all of said heat generating elements independent of the recording information and permit simultaneous application of plural drive signals to plural said heat generating elements such that no two adjacent heat energy generating elements can be driven simultaneously.
