Abstract
A device for reproducing an image of an original by using photosensitive material and transfer material for receiving an image formed on the photosensitive material. The original is optionally scanned to produce an optical signal which represents an image of the original, and the photosensitive material is exposed in accordance with the optical signal from the scanner together with the movement of the photosensitive material in synchronization with the scanning. A developer device superposes the exposed photosensitive material on the transfer material and spreads a developer between the superposed photosensitive material and transfer material so as to reproduce the image on the transfer material.
Claims49
An image reproducing device for reproducing an image of an original using a photosensitive film and a transfer material for receiving an image formed on said photosensitive film, comprising:
- a scanning means for optically scanning a surface of an original, said surface being to be reproduced, in a predetermined direction, while generating sequentially light beams reflected from each of portions of said scanned surface;
- a supply means for supplying said photosensitive film;
- an exposure means for exposing said supplied photosensitive film, said exposure means comprising a pair of tension rollers and an exposure station, a pair of said tension rollers being adapted to rotate at a somewhat higher circumferential speed than a speed of said supplied photosensitive film so as to exert a tension on said supplied photosensitive film, said exposure station being situated in an image forming position of said generated light beams between said supply means and said tension rollers for exposing said supplied photosensitive film, and having a flat surface positioned at a height identical with or higher than a height of a straight line connecting a position of said photosensitive film supplied from said supply means with a nip of said tension rollers, said flat surface contacting with said supplied photosensitive film;
- and
- a developing means for superposing said exposed photosensitive film on said transfer material and for spreading a developer between said superposed photosensitive film and said transfer material.
An image reproducing device for reproducing an image of an original using a photosensitive film and a transfer material for receiving an image formed on said photosensitive film, comprising:
- an exposure means for forming a latent image of said original on said photosensitive film by an exposure;
- and
- a developing means for superposing said photosensitive film exposed by said exposure means on said transfer material, said developing means being provided with a pair of spreading rollers for spreading a developer between said superposed photosensitive film and said transfer material, with front ends of said exposed photosensitive film and said transfer material being aligned by striking said front ends thereof against said spreading rollers when said spreading rollers are not rotating, said transfer material comprising a transfer member and a developer sealing member, a front end portion of said developer sealing member being fixed to a front end portion of said transfer member and a rear end of said developer sealing member being free, said exposure means comprising a guide member for superposing said exposed photosensitive film on said transfer material, said guide member guiding said exposed photosensitive film so that said exposed photosensitive film runs over said developer sealing member of said transfer material to come into contact with said transfer material.
An image reproducing device for reproducing an image of an original using a photosensitive film and a transfer material for receiving an image formed on said photosensitive film, comprising:
- a scanning means for optically scanning a surface of said original, said surface being to be reproduced, in a predetermined direction, while generating sequentially light beams reflected from each of portions of said scanned surface;
- a sending means for sending forth said photosensitive film;
- an exposure means for exposing said sent photosensitive film, said exposure means comprising an exposure drum, on a surface of which an image of said original is formed, said exposure drum being adapted to be rotationally driven at a speed greater than that of said sent photosensitive film so as to exert a tension on said sent photosensitive film;
- and
- a developing means for superposing said exposed photosensitive film on said transfer material and for spreading a developer between said superposed photosensitive film and said transfer material.
