Abstract
PURPOSE:Uneveness of development for facsimile unit is prevented by stopping rotation of driven elements such as magnet roll and the others and synchronizing rotation of cliven elements and step motor by using retarding torque of step motor. CONSTITUTION:Back roll 23 of facsimile receiver and the others is driven intermittently by step motor 28 via gear 33, while magnet roll 25 is driven by torque motor 31 via gear 34. Magnet roll 25 and back roll 23 are connected together by belt 32a. Under the condition that output torque for magnet roll 25 on the side of torque motor is smaller than retarding torque and number of revolutions at the side of torque motor is faster than retarding torque at the step motor side, uneveness of development for recording chart is prevented, because magnet roll 25 can be synchronized with back roll 23.
