Method of transferring photosensitive material and apparatus used therefor

The present invention relates to a method of transferring photosensitive material and apparatus used therefor. More particularly, the present invention relates to a method of transferring strip-form photosensitive material (hereinafter called "paper") and an apparatus used therefor which can transfer the paper in such a manner to prevent a difference between the predetermined feed size, in particular, when the paper head end portion is sent out only by feed rollers (the size is a print size corresponding to one image which is intermittently sent by a transferring device). If, for example, film has mixed images of varying print sizes, such as full size or panorama size, each adequate predetermined length of the paper, corresponding to the relevant one image, is sent out, and the feed size, when the paper head end portion is transferred after being sandwiched between transferring rollers, and with back tension between the transferring rollers and the feed rollers. The present invention also relates to a method of transferring the paper and apparatus used therefor, which can accurately form a punch hole on the paper for serving as a positioner when the photosensitive material is transferred. A method or transferring a strip-form photosensitive material comprising mounting a feed roller on an upstream side and a transferring roller on the downstream side with an exposure table located therebetween and intermittently transferring the photosensitive material onto the exposure table only in the predetermined feed size, characterized by measuring in advance a feed size of the paper based on number of revolution of the feed roller and a feed size of the paper based on number of revolution of the transferring roller and compensating for the number of revolution given to both rollers in order to prevent an error generated between both paper feed sizes. It is possible to accurately transfer the same size as that after the paper is sandwitched between the transferring roller even when the paper head end is not yet sandwitched between the transferring roller and is sent out only by the feed roller, because the paper feed size based on the number of revolution of the feed roller is controlled to be the same as the paper feed size based on the number of revolution of the transferring roller.
