PURPOSE: To provide a drive system which can be simplified in a circuit configuration by controlling the recording start or end of a recording head specified by a specific signal when the comparison result of an address data with a numeric data coincide.

CONSTITUTION: A CPU 10 outputs K1 through an output port 21 to a comparator 12 upon inputting of a pulse signal Z, and sets the other input of an AND gate 23 to a high level through an output port 28. A counter 11 which is reset by the pulse signal Z counts the pulse signals B, and when the counted value becomes K1, the output of the comparator 12 becomes high level, the D terminal of D-FF 22 becomes high level, is then set at the timing that the pulse signal B becomes high level, and the Q output becomes high level. The other input of the AND gate 23 is high, the D-FF 29 is reset, and the D input is high. Accordingly, when the Q output of the D-FF 22 is inverted to high, an FF 23 is set, the Q output becomes high, and the pulse signal Py rises.
