PURPOSE:To switch and transfer power with accurate timing by including a planetary gear energizing with a sun gear provided freely rotatable at an arm, a pair of gears arranged keeping a gap in the circumferential direction of the sun gear, and a means which initializes the planetary gear in a state engaging with one of the pair of gears. CONSTITUTION:In transmission/reception facsimile equipment, an original 1 is carried by sandwiching with a pair of rollers 3, 4 via a guide member 2 in transmission, and it is carried in a direction of arrow head 6 via a guide member 5. The sun gear 15 is fixed at a rotary shaft 16, and is driven rotatably by a pulse motor 30 rotating in forward/backward directions. The sleeve 18 of the arm 17 is inserted to the rotary shaft 16, therefore, the arm 17 can be rocked around the rotary shaft of the sun gear 15. The planetary gear 19 engaging with the sun gear 15 is provided at the arm 17. The planetary gear 19 can be engaged selectively with driven gears 13, 14. The driven gears 13, 14 are arranged keeping the gap in the circumferential direction of the sun gear 15. |
