[Table] In this way, each bit b ₀ of each channel CHA to CHE in the film type identification indicator
In ~ _b3 , in order to provide information for identifying the film type, the * mark of each bit is painted black when there is a signal, that is, when the signal is "1",
When there is no signal, that is, when the signal is "0",
Leave it white and create a film type identification mark. Although not particularly shown, pallet stocker 4 (first
Figure) consists of a shelf for document storage on the first stage, a shelf for storing unexposed film and temporary storage on the second stage, a temporary storage shelf on the third stage, and a shelf for ejecting the fourth stage. The hand member 18 moves up and down and is placed at a position where it is easy to take out a suitable film. Next, an explanation will be given of the operation when multiple printing is performed according to this embodiment. 11A, B, and C are flowcharts for explaining the operation of the master plate production robot of this embodiment. It represents the order of reading processing into the device 2. Also,
The sequence numbers (1) to (31) of each operation to be described later are shown by assigning the same numbers to the corresponding parts of the flowcharts of FIGS. 1A, B, and C. This multi-printing process involves printing photos, illustrations, etc. on unexposed film according to the layout of the printed material
This is a process in which characters, lines, etc. are repeatedly exposed to light many times. Documents required for exposure in multiple printing operations include original films for photographs, illustrations, letters, and lines, as well as masking films for masking unnecessary portions of the layout. The quantity of these originals is different for each printed item, so in multiple printing work, when the originals and unexposed film are brought into close contact with each other during exposure, due to the nature of each original and unexposed film, the order in which they are stacked by type is different. It's decided. For example, as shown in FIG. 12, a mask plate or character plate 31 is set at the bottom of the surface of the printer glass 30, and a duplex plate 32, a print plate 33, and an unexposed film 34 are sequentially placed thereon. superimpose on In this operation, up to four unexposed films 34 are replaced and exposed for one mask plate 31. However, the mask plate 31 is the printer glass 30.
Because it is set at the bottom of the screen, eject it after exposing up to four images. Therefore, most of the information for distinguishing the type of film to be superimposed on the mask plate 31 can be collected from the mask plate 31. Also, Dakase version 3
2 is set immediately above the mask plate 31, but depending on the layout of the printed matter, the duplex plate 32 may not be necessary,
Since there are cases where it is necessary to handle the situation with just one copy of the copy plate 32, the copy copy plate 32 may be temporarily stored. Furthermore, there are cases where a plurality of sheets (up to two sheets) of the duplex plates 32 are stacked. The printing plate 33 is set so as to be in immediate contact with the unexposed film 34. That is, it is set on the duplex plate 32 or, if there is no duplex plate 32, on the mask plate 31. This printing plate 33 is discharged after exposing the unexposed film 34 once. As mentioned above, when performing multiple printing work,
If the following information is marked as the above-mentioned film type identification mark affixed on each film such as a mask version, a letter version, a duplex version, or a paperback version, the information detection sensor 21 attached to the hand member 18 of the robot reads the film type identification mark of the film, and the robot main unit performs multiple printing operations instead of humans, according to the flow chart shown in FIGS. 11A, B, and C.
