Abstract

By controlling the force applied by the hammer mechanism, it is possible to effect even imprinting of characters. A key 10 for positioning a type member 11 also connects a resistor 12 in series with an actuating solenoid 14 for the hammer mechanism 15. Each resistor limits the field current of the solenoid, thus controlling the velocity of the throw of the hammer mechanism. The resistances vary in accordance with the area of the character to be printed.
