Abstract

PURPOSE:To enable to reduce by half the quantity of recording medium in a printing machine for an information processor by arranging a pair of typing heads at relative positions and printing on both side surfaces of the medium while moving synchronously the heads in the same directions. CONSTITUTION:A clutch 13 is engaged in accordance with a typing operation start command, the rotation of a motor 14 is transmitted through a shaft 12 to pulleys 8, 9, typing units 2, 3 are moved synchronously, printing information is provided, and both sides are simultaneously pinted. Since the units 2, 3 move synchronously with each other, the unit 2 prints forwardly, the unit 3 prints backwardly, and when one line is printed completely, a recording sheet 1 is fed upwardly by one line, and a printing of next line is performed in a direction opposite to the previous printing. This control can be performed by inverting the information logic of the software of a controller.
