1. Field of the Invention
The present invention relates to a device for automatically supplying/discharging photosensitive material such as a presensitized plate (referred to as "PS plate" hereinafter) in an inclined-type step and repeat machine having a rearwardly inclined exposing table.
2. Description of the Prior Art
FIG. 1 is an elevation view of an inclined step and repeat machine equipped with a device for supplying/discharging photosensitive material according to a preferred embodiment of the invention;
FIG. 2 is a partially cutaway perspective view of the machine;
FIG. 3 is a left side elevation view of the body of the machine;
Now referring to the drawings, there are described below preferred embodiments of the invention.
FIG. 1 is an elevation view of an inclined step and repeat machine equipped with a supplying/discharging device according to an embodiment of the invention, FIG. 2 is a partially cutaway perspective view of the body of the machine, FIG. 3 is a left elevation side view of the body of the machine, FIG. 4 is a right side elevation view of the device omitting a side board thereof for convenience of illustration, in which 2 denotes the body of the machine and 4 designates the supplying/discharging device.
In FIG. 3, an exposing table 6 on which photosensitive material such as a PS plate is positioned and secured by means of register pins (not shown) is rearwardly inclined at an angle of .theta., for example, 70.degree. or so with respect to the horizontal as illustrated in FIG. 3. A light source and an original film holder (not shown) are incorporated in a carrier unit 8 movable up and down on a moving frame 10, which is so designed as to move transversely of the exposing table 6. In step and repeat operations, the original film holder mounted in the carrier unit 8 is moved to a desired position on the PS plate on the exposing table 6 while the frame 10 and the unit 8 are being moved properly, so that the light source repeats the act of exposing through the original film the plate after the original film in the holder (as positioned) is brought into direct contact with the PS plate, thus effecting the printing.
