CONSTITUTION:When data on the size of paper to be printed is entered through a memory key or ten keys, a motor 77 rotates to allow the data to be entered into a potentiometer 90 and a differential gear mechanism 85. Then the outer gear 91 of the differential gear mechanism 85 rotates and the inner gears 92, 93 are allowed to rotate. However, the inner gear 92 is connected to gears 73, 71, 32 and fixed by a braking device so that the gear does not move. In the meantime, the inner 93 is connected to a coupling 87, a differential gear 86, gears 74, 72 and an outer cylinder section 33. If the inner gear 93 is caused to rotate by using the difference between the numbers of teeth of the inner gears 92, 93 to rotate a paper end holding device 34 to the specified size of paper based on a claw device 55, the potentiometer 90 selects the paper size and connects a stop signal to the motor 77. Simultaneously with the stopping of the motor 77, a brake works to make a shaft 81 stationary, thus completing the changing-over of paper size.
