Abstract

PURPOSE: To make an apparatus smaller and perfecting rotation prevention of a plunger shaft without special working of the shaft bearing etc. by preparing the guide part of the plunger shaft of the plunger type hammer outside of the plunger driving body.
CONSTITUTION: The plunger shaft 18 connected with a plunger moves leftward and strikes with its tips the back of a type 24 and letters on a paper 25 by the force generated between the plunger and the yokes 15, 16 by current supply to a coil. On this occasion the tip of the plunger shaft 18 moves without rotating because it has a long shaped cross-sectional part 27 in accordance with the shape of the type back and is held by the guide part 29. The guide part 29 is set to the elastic guide plate 30 attached to the carriage 31 etc. and provides the shaft 18 with return force, and at the same time visibility of letter is improved because it is outside of the driving body 22.
