Abstract
PURPOSE: To minuaturize a printer and to improve the printing quality, by housing a hammer mechanism in a type wheel, and performing the rotation of the type wheel, and the feeding of paper by a pulse motor.
CONSTITUTION: Before printing, pulse signals are applied at out of timing successively to the pulse motor and when every pulse signal is applied the type wheel is rotated by a certain degree. Then when command is issued from a control circuit for printing a specified letter, the type wheel is stopped at a prescribed printing position, an electric current flows through the coil 31 of a selected plunger 34 and a movable iron core 30 is attracted. As a result the hammer 23 moves forward, and a striking part 24 strikes a selected projection 10 of the type wheel, so that the printing paper 99 is pushed against a platen 76 to perform printing. In this occasion, the resilient type belt is extended to print securely.
