PROBLEM TO BE SOLVED: To provide a recording apparatus which eliminates the need of changing a logic circuit of an apparatus body even when a driving pattern of a recording head is changed. SOLUTION: A printing trigger signal-generating circuit 39 is a circuit for generating a printing trigger signal. A head logic CLK-generating circuit 40, a printing data-converting circuit 38 and a data transfer CLK-generating circuit 37 are started to operate by the trigger signal. The head logic CLK-generating circuit 40 generates a logic CLK for operating a printing pulse-generating circuit 35 and a block select signal (SEL)-generating circuit 34 held inside recording heads 9A-9D. The logic CLK is a CLK obtained by multiplying a system CLK of the printer body by a fixed rate. The data transfer CLK-generating circuit 37 is a circuit for generating a printing data transfer CLK for transferring recording data to a shift register 33 held in the heads.
