ABSTRACT:
A miniature printer includes character rings, each having a series of characters on the outer periphery thereof and teeth on a side surface thereof for selection of a character to be printed. The shaft carrying the character rings also has mounted thereon a radially-slotted disc through the slots of which a light beam is passed for signalling the angular position of said shaft, the light beam being directed at light-detection means. Electronic circuitry controls pawls for selectively stopping the character rings so that a selected character on each ring is brought to rest at a printing position for printing. The electronic circuitry also controls the intermittent feed of printing paper and printing ribbon. A gear-selection mechanism provides for a plurality of printing-paper feed rates as well as for holding the paper stationary when required.
A number of the components are of unitary contruction to increase the ease of assembly and decrease the costs as well as the number of parts. In addition, a number of the parts can be housed in an individual case so that the parts can be handled as a unit.
