Abstract

PURPOSE:To eliminate completely movement and distortion at the running time generated in a film driving system to prevent malfunctions, by obtaining a maximum curve of the film driving speed on a basis of the film length obtained from the difference between the current position and the retrieval position of the film to be retrieved. CONSTITUTION:Information of a frame position to be retrieved of a microfilm 3 set to an operating part (a) is supplied to a control part (b), and information to be displayed on a numeric display equipment of the operating part (a) is given from the control part (b). This control part (b) consists of a microcomputer, etc., and an optimum curve of the driving speed of the film 3 is operated on a basis of retrieval position information from the operating part (a) and the current position of the film 3 from an optical detecting part (c) which detects the driving state of the film 3. On a basis of this operation result, brakes 21 and 22 of driving shafts 19, 20, 15 and 16 provided between spools 23 and 24 and a stepping motor 11 which drive the film 3 are controlled to prevent completely movement and distortion at the running time generated in the film driving system.
