装置の感材供給装置。[Scope of claim for utility model registration] In order to rotate the photosensitive material sheet within the optical path for exposure,
A drum is rotated by a drum drive motor so that the photosensitive material sheet is wrapped around the outer circumferential surface by air adsorption, and a motor drive rotor is rotated so as to make contact with the photosensitive material sheet, and the photosensitive material sheet is rotated by the rotation. a feed roller that feeds the photosensitive material sheet to the drum; a detection device that detects the moving speed of the photosensitive material sheet before it is wound around the drum near the feed roller; and a feed roller that detects the feeding speed of the photosensitive material sheet relative to the rotational speed of the drum based on the detection data from the detection device. 1. A photosensitive material supplying device for an exposure apparatus, comprising: control means for controlling at least one of the drum drive motor and the roller drive motor so that the speed thereof is relatively increased.
