摘要:
A lamp unit (A) for use in an electrophotographic copying apparatus, moves under an original on the original support. The lamp unit (A) is formed with a slit (2) through which the light from the lamp (1) is shed on to the original and reflected by it on to a photo-sensitive object to form an image thereon. The slit (2) is the narrowest at its center and gradually widens toward its both ends. Also, the lamp unit (A) is accelerated until it reaches the center of the original support and is decelerated thereafter. This assures a uniform distribution of light over the surface of a photosensitive object.

A photographic copying apparatus for reproducing an image of an original on a sheet of photosensitive paper. A roll of photosensitive paper (S) mounted in a magazine (27) is fed downwardly and cut into sheets. Each sheet is sucked to a vertically arranged suction conveyor (22) and fed down. When it reaches a predetermined position, the feed of the sheet stops. An exposure table (1) which is turnable and movable between two points is turned to its upright position and pressed against the sheet on the conveyor. In this state, the suction conveyor stops sucking the sheet while the exposure table starts sucking it, so that the sheet is handed over to the latter. The table now carrying the sheet moves toward the other end for exposure. On its way, it is turned to bring the sheet carrying side up and passed under a corona charger (54). As the table reaches the other end where there is provided an exposure unit, it is turned again to an upright position. In this state, the light reflected by an original is shed on the sheet for light exposure. The table is then turned to bring its sheet carrying side down and moved in an opposite direction toward the conveyor. On its way, the sheet is brought into contact with one of several kinds of developing solutions in tanks which are adapted to be raised into contact with the sheet one after another. Any excess solution applied to the sheet is then removed by a squeezer (58). After this first development cycle, the table is turned by 180 degrees and moved toward the exposure unit again for another cycle of development. This cycle is repeated as many times as the number of colors used.

A printing device of the present invention includes a printing head for carrying out a printing operation on one side of a surface of a disk, such as a CD-R medium, and arranged such that the printing operation is performed on the disk as the disk and the printing head are relatively shifted by the rotation of the disk.
