Abstract: An apparatus automatically feeds photosensitive printing plates having the characteristic that transport and storage are possible in a state where the photosensitive printing plates have been stacked together such that back sides of the photosensitive printing plates are brought into direct contact with photosensitive surfaces on front sides of the photosensitive printing plates. The apparatus includes: a storage member that accommodates a bundle comprising a plural number of the photosensitive printing plates stacked together without slip sheets; a takeout member that separates and takes out the photosensitive printing plates from the bundle one plate at a time; and a conveyance member that conveys the taken-out photosensitive printing plates to an exposure apparatus. According to this apparatus, the conventional configuration and process of separating, conveying, and stocking slip sheets from the photosensitive surfaces of the photosensitive printing plates can be omitted.
