Abstract

PURPOSE: To prevent the over-revolution of a type member, to improve the speed of printing and to better the quality of printing, by a mechanism wherein a plunger is selectively connected to a connecting member rotating interlocking with the type member.
CONSTITUTION: A revolution angle detecting plate 3, a type member 6 and a connecting member 4 manufactured by forming connecting portions 4a at locations, whose number is the same as type on the type member 6 and which correspond in 1 to 1, are fixed to a shaft 2 of a stepping motor 1 so taht they be rotated in interlocking shapes. A plunger solenoid 5 is mounted which is provided with a plunger 5a, which rushes into the connecting portions 4a installed to the connecting member 4 and connects the connecting portions. When the stepping motor 1 over- rotates, the plunger 5a also crosses the bottoms B of the V-shaped grooves of the connecting portions 4a, and faces to one side inclined planes S in a shape that is shifted only by distances L. Thus, when the plunger 5a runs into the connecting portions 4a, over-revolution is forcedly pulled back because a nose T slides on the inclined planes S and plunges into the bottom portions B.
