Abstract

PURPOSE: To provide a correct printing operation by a mechanism wherein a selective stopping action of a type wheel is used simultaneously as a signal for starting a pressing action of a platen roller.
CONSTITUTION: When the rotation of a motor MO is transmitted to a type wheel 1 through gears 7, 6, driving gear 5, planetary gear 4, holding disc 3 and driving shaft 2 and the desired type comes to a position directly before the printing position, a printing instruction is inputted to an electromagnetic device Mg to deenergize the latter. The deenergization causes a bent portion 16b of a change-over lever 16 to push a ratchet pawl lever 19, thereby restricting a ratchet wheel 9 and stopping the type wheel 1, while making a pin 19a retract from a notch 14a of a cam disc 14, and making platen roller 10 revolve through a platen shaft 12, and causes the roller 10 to press the type wheel 1 for printing on the printing paper 20. After completion of printing, the rotation of an eccentric cam 18 pushes a pin 16c upward, thereby causing a pole contacting portion 16a of the lever 16 to be attracted to and held on the permanent magnet of the device Mg. Simultaneously, the engagement between the lever 19 and the ratchet wheel 9 is released, the pin 19a is advanced into the notch 14a and the type wheel 1 is rotated.
