Abstract

PURPOSE: To optimize the transmission efficiency and simplify a mechanism for moving a type body in the axial direction by linking a motor to the type body with a gear mechanism.
CONSTITUTION: By setting the gear ratio to be stipulated as J1=(Z1/Z2)2J2 where the inertia moment of the rotor of a motor 1 including a motor gear wheel 2 is J1, the inertia moment of the follower side including a gear wheel 5, a boss 6 and the type body 8, is J2 number of teeth of the motor gear wheel 2 is Z1 and the number of teeth of the gear wheel 5 is Z2, the rotational force of the motor 1 can be transmitted to the follower side most efficiently. When a type 9 positioned in the lower stage of a type blade 10 is used for printing, a plunger 14 is attracted into an electromagnet 13, a lever 15 is rotated at a certain angle around a shaft 16 to raise the tip of a roller 17 side, and thereby the type body 8 is raised by the distance of an interval between the types 9 positioned on the upper and lower stages along a shaft 4 together with the gear wheel 5 and the boss 7.
