A printer which includes a movable type body and a solenoid system to move the type body is provided. The solenoid system comprises a plurality of opposing pairs of solenoids, each pair being connected together so as to provide simultaneous displacement of both solenoids in a pair when one of the solenoids of a pair is energized. The several pairs of solenoids are interrelated with respect to their relative displacements and the sum of all of the displacements is transmitted to the type body for selection of a position on the type body. The solenoid system may include a pulley system or a differential lever system for the purposes of transmitting the sum of the displacements to the type body. |
