Abstract
A type carrier for use in an impact-type printing machine to form an imprint of virtually the equal quality when used with either a flat hammer or a detentable, shaped hammer is provided. The present type carrier includes a hub and a plurality of fingers extending from the hub, each finger having a printing section which has a front surface provided with at least one type and a back surface having a novel structure. The back surface of the printing section includes at least one flat portion and at least a pair of sloped portions. Preferably, the sloped portions are defined such that they slope down oppositely from a plane common to or below the flat portion in the direction substantially perpendicular to the lengthwise direction of the finger.
