Abstract

PURPOSE: To stabilize the stop positon of a type wheel and improve quality of letters by providing a ratchet wheel united with the type wheel to prevent reversal and proceed stepwise and controlling the ratchet catching the ratchet wheel by the signal from a code plate.
CONSTITUTION: The pulse motor 35 starts to rotate according to printing instruction, a type wheel rotates stepwise through the gears 37, 42. In this time S, R corresponding to th even number series and the odd number series of the type belts 5 of the type wheel 4 are taken out from the contact piece 38 contacting to the code plate 36, and home position signal TR is from code signal, the code plate 44 and the contact piece 45. Signals S, R start to count by this home position signal, stop the pulse motor 35 at the position of the type to be printed, energize also the stop solenoid 48, pull the armature 49 and make the hook part 52b of the ratchet 52 engage the ratchet wheel 43 and stop the type wheel surely.
