Abstract
A travel roller moves between the initial and the end points in a loosening unit while supporting a photosensitive material to thereby form a loop thereof. A first sensor, for detecting that the travel roller locates on the end point, is provided in the loosening unit. When it is not detected at the end of recording that the travel roller locates on the end point, a portion of the photosensitive material is cut off, whereby the photosensitive material is divided into a sheet with a reproduced image and an unexposed photosensitive material. The unexposed photosensitive material is rewound until a leading edge portion thereof reaches a recording unit, and then an image to be reproduced next is recorded onto the unexposed photosensitive material.
Claims8
An apparatus for recording an image, comprising:
- a feeding unit for feeding a photosensitive material in a first direction;
- a loosening unit including a travel roller for supporting said photosensitive material from said feeding unit, said travel roller moving between initial and end points in a second direction approximately perpendicular to the first direction in order to form a loosening in said photosensitive material;
- a first sensor for detecting that said travel roller locates on the end point;
- a recording unit for recording an image to be reproduced onto said photosensitive material;
- a cutting unit for cutting off a portion of said photosensitive material, to thereby divide said photosensitive material into a photosensitive material sheet with the reproduced image and an unexposed photosensitive material;
- and
- a controller for controlling said feeding, loosening, recording and cutting units which are disposed serially in the first direction,
- wherein, when said first sensor does not detect at the end of recording that said travel roller locates on the end point, an image to be reproduced next is recorded onto said unexposed photosensitive material by said recording unit after said portion of said photosensitive material is cut off by said cutting unit and then said unexposed photosensitive material is rewound until a leading edge portion of said exposed photosensitive material reaches said recording unit.
A Method of recording an image, comprising steps of:
- feeding a photosensitive material in a first direction until a leading edge portion of said photosensitive material reaches a recording position;
- loosening said photosensitive material in a loosening position to thereby form a loop of said photosensitive material, the loosening position being upstream from the recording position relative to said first direction, a size of said loop being within a predetermined range;
- recording an image to be reproduced onto said photosensitive material;
- cutting off a portion of said photosensitive material to divide said photosensitive material into a photosensitive material sheet with the reproduced image and an unexposed photosensitive material;
- detecting at the end of recording whether a size of said loop is within the range or not;
- and
- rewinding said unexposed photosensitive material until a leading edge portion of said unexposed photosensitive material reaches the recording position if it is detected that the size of said loop is within the range, and thereafter recording a next image onto said unexposed photosensitive material.
