Filed: 1984-07-09
Abstract: PURPOSE:To shorten the entire moving width of a magnetic head, by changing the interval between magnetic heads at the time of operations, such as data writing, data reading, etc., from that at the time of waiting. CONSTITUTION:A motor M1 is actuated and it is discriminated whether or not the motor M1 is driven until a head H1 is moved and a prescribed interval is set between the head H1 and another head H2. When the motor M1 is driven until the interval between the heads H1 and H2 becomes a prescribed one, another motor M2 is actuated and the head H2 is moved. When the head H1 reaches the final end of paper and the motor M1 can be stopped while the motor M2 is driven, the motor M1 is turned off. Then it is discriminated whether or not the head H2 reaches the other final end of the paper and the motor M2 is to be stopped and, when the head H2 reaches the final end position, the motor M2 is turned off, and thus the operation is terminated. Therefore, the moving distances of the heads at the time of operation and waiting can be shortened and, as a result, the writing device using this invention can be miniaturized.
