ABSTRACT:
A simplified and compact typing machine to be incorporated in an electronic calculator has a type wheel for presenting different numerals upon rotation. The type wheel is moved along a line of digits, i.e., laterally and in the generally horizontal direction, for typing successive numerals and the typing is performed when a hammer head is swung, or the type wheel is rotated, by the movement in one direction of an acting rod of an electromagnetic relay. The same relay acting rod also laterally moves the type wheel in the direction of the line of digits, on its return motion, by a distance corresponding to the space of one digit.
