Abstract
PURPOSE: To provide a space control circuit for a serial peinter in which the time spent in moving the carrier uselessly can be eliminated by determining the direction of carrier return from the result of comparison of the present position of the carrier and the center of the carrier movement range and the signal of direction of the carrier movement.
CONSTITUTION: The circuit possesses a present position memory 2 and center margin memory 4 that stores the centers of carrier movement range, and also possesses a means 6 that compares the stored content in both memories upon arrival of the signal for the end of printing, and further possesses a direction determination means to determine the direction of the carrier movement for returning to the marginal position after the printing operation is finished by receiving the result of comparison at the means of comparison and the direction signal that indicates the carrier movement direction during the printing operation.
