Abstract
PURPOSE: To obtain the small serial printer having simple printing mechanism, excellent printing quality and quiet printing noise by a method wherein printing is carried out by the revolution of an oscillating lever generated when the rotation of a type wheel carrying types is locked.
CONSTITUTION: When desired type on the type wheel 3 rotated by the main shaft 1 appears at the type position, if electric current is supplied to an electric magnet 15 by the signal of a detector 21, an operating lever 13 rotates a locking pawl 8 in an arrow A direction, interlocks with corrugated teeth and arrests the rotation of the type wheel 3. This makes selective operation of types 4. The type wheel 3 where rotation has been arrested begins to revolve around the main shaft 1 at the revolving speed given by the teeth of both a driving gear 2 and its following one 5 and moves in an arrow B direction of an oscillating lever 11. This makes printing operation. As the oscillating lever 11 moves in the arrow B direction, the locking pawl 8 obtains operating power in an arrow C direction by a lock-releasing body 12, releases the type wheel 3 from its locking, the oscillating lever 11 oscillates in an arrow D direction by a controlling spring 24 and the printing operation is completed.
