    • Disclosed is a method and an apparatus comprising a feed control apparatus (500) for a lengthy photographic film (110) which includes a rotation control means (190) for calculating a winding diameter of a film roll (116A, 116B) on the basis of a number of revolutions of a driving motor obtained when the lengthy photographic film is fed in a predetermined length corresponding to a pre set film size from the film roll with the lengthy photographic film wound thereon, and for calculating a number of revolutions to be used to feed the lengthy photographic film in the predetermined length within a predetermined period of time on the basis of the winding diameter so that the number of revolutions is used as a corrected number of revolutions; and a motor control means (202) for making feedback control so that the number of revolutions of the driving motor is changed to the corrected number of revolutions within a predetermined period of time, while comparing the corrected number of revolutions supplied from the rotation control means (190) with a current number of revolutions of the driving motor (112).
    • 公开了一种方法和装置,包括用于长时间的照相胶片(110)的进给控制装置(500),其包括用于基于以下步骤计算胶卷(116A,116B)的卷绕直径的旋转控制装置(190) 当长时间的照相胶片以卷绕在其上的长时间的照相胶片的胶片卷以相当于预定胶片尺寸的预定长度进给时,获得的驱动电机的转数,并且用于计算用于 基于卷绕直径在预定时间段内将长时间的照相胶片进给到预定时间段,以使转数作为校正转数; 以及电动机控制装置(202),用于进行反馈控制,使得在预定时间段内将驱动电动机的转数改变为校正转数,同时比较从旋转控制装置提供的校正转数 (190),其具有驱动电动机(112)的当前转数。
