Abstract

PURPOSE: To stabilize the printing action by providing a guide member between the adjacent printing hammers and thereby preventing the spring of the hammer from being bent when it is in the compressed state in the printing hammer device which acts by the electromagnetic force.
CONSTITUTION: The printing hammer 21 moves to the right for printing against the spring force of the spring 25 by the attracting force of an electromagnet 33. On the occasion, the spring 25 turns to be in the compressed state, and the vertical curvature in this state is corrected by the guides 22 and 23, while the horizontal curvature is corrected by the guide 35, whereby the contact of the printing hammer 21 with the spring 25 and also the contact of adjacent springs 25 with each other are eliminated. For the guides 22, 23 and 35 is used the resin whose friction coefficient is small and which has abrasion resistance property and the guide 22 and the guide 35 can be formed in one body.
