ABSTRACT:
A small-sized printing apparatus which operates at a low noise level and provides good printing quality includes a plurality of printing rings, each having type characters on the peripheral surface thereof. The printing rings are mounted on a shaft which reciprocates for the purpose of bringing a selected character on each of the rings to a printing position. The shaft reciprocates through forward and reverse directions of rotation. An inking roll transfers ink intermittently to the type characters.
