Method of transferring photosensitive material and apparatus used therefor

An apparatus for transferring a strip-form photosensitive material comprising a feed roller mounted on an upstream side and a transferring roller on a downstream side with an exposure table located therebetween, and a control mechanism for controlling numbers of revolution of the both rollers in order to intermittently transferring a strip-form paper onto the exposure table only by a predetermined size, characterized in that the control mechanism compensates for the feed size of the paper based on the number of revolution of the feed roller and the feed size of the paper based on the number of revolution of the transferring paper so as to prevent any difference from being generated between the two feed sizes.

A method of transferring a strip-form photosensitive material comprising providing a feed roller mounted on an upstream side and a transferring roller on a downstream side with an exposure table located therebetween and a control mechanism for controlling numbers of revolution of the both rollers in order to intermittently transferring a strip-form paper onto the exposure table only by a predetermined size, characterized by controlling the predetermined feed size based on the number of revolution of the feed roller until a paper head end is sandwitched between the transferring roller and controlling the predetermined feed size based on the number of revolution of the transferring roller after the paper is sandwitched between the transferring roller;

• and if the predetermined size of the paper is unable to be sent out by the feed roller only and is sandwitched between the transferring roller, stopping the rotation of the feed roller just before the paper is sandwitched between the transferring roller, computing the size short for the predetermined feed size by computing the feed size which the feed roller has sent, computing the number of revolution of the transferring roller corresponding to the computed value, and rotating the transferring roller only as much as the computed value.

A method of transferring a strip-form photosensitive material comprising sending a strip-form paper stored and held with the paper being wrapped in a roll form onto an exposure table by a feed roller and transferring the paper with the head end being sandwitched between the transferring roller, characterized by transferring the paper with the paper mask mounted on the exposure table being closed until a head end of the paper is sandwitched between the transferring roller.

A method of transferring a strip-form photosensitive material comprising sending a strip-form paper stored and held with the paper being wrapped in a roll form onto an exposure table by a feed roller and transferring the paper with the head end being sandwitched between the transferring roller, characterized by keeping transferring speed of the photosensitive material slower than normal transferring speed till a head end of the photosensitive material is sandwitched between the transferring roller.

An apparatus for transferring a photosensitive material comprising an exposure table for printing an exposing the paper, a paper mask mounted on the exposure table, a feed roller disposed on an upstream side of the exposure table and a transferring roller disposed on a downstream side of the exposure table, characterized in that the paper mask is kept closed when a head end of the paper is sent out onto the exposure table with the feed roller until the head end is sandwitched between the transferring roller.

An apparatus for transferring a photosensitive material comprising an exposure table for printing and exposing the paper, a paper mask mounted on the exposure table, a feed roller disposed on an upstream side of the exposure table and a transferring roller disposed on a downstream side of the exposure table, characterized in that transferring speed is kept slower than normal transferring speed when a head end of the photosensitive material is sent out onto the exposure table with the feed roller until the head end is sandwitched between the transferring roller.

An apparatus for transferring a strip-form photosensitive material comprising a plurality of driving rollers arranged along a transferring route for transferring a strip-form paper via an exposure table, characterized in that the relative difference of capabilities of feed rate in adjoining driving rollers is adjusted to be smaller for driving rollers on an upstream side than for driving rollers on a downstream side.
