Abstract

PURPOSE: To provide a typewriter which sets right and left margin positions at a control part through a continuous single action under such mechanism that a recording head scans at the depression of a push-button on a margin set key and reading a distance to the right and left margin positions from a home position.
CONSTITUTION: In a typewriter where right and left margin positions can be independently set, a head moves until it detected right and left margin positions starting from a home position at the depression of a single margin set key and the value of a counter at time of detection is memorized at a control part. The counter moves to right from a home position as 0 which movement means "plus" and moves to left which signifies "minus". The pulses generated every fixed rotary angle of a motor has only to be counted. As a result, the right and left margins are set at positions 1, 3, and then printing is performed. Where a shift to the fifth line is carried out, only the left margin has to be changed to a position 2 and the right margin is automatically changed to a position 4.
