- A
motor gear 6 is arranged at the output shaft 5A of the driving motor 5 and atransmission gear 7 for use in transferring the driving force of the driving motor 5 to either the sheet transferring mechanism or the sheet cutting mechanism is engaged with themotor gear 6.

- At this time, in the case that the sheet is transferred during the printing and the like, the driving motor 5 is driven to rotate in a normal direction, the
oscillation gear 21 is engaged with theroller driving gear 4 and its driving force is transmitted only to the sheet transferring mechanism. That is, at this time, since theoscillation gear 22 is not engaged with thecutter driving gear 19, the sheet cutting mechanism is not driven. - Then, upon completion of the predetermined printing, the sheet of appropriate length is transferred to cause the printed sheet portion to be discharged out of the
