For example, in the case of a film with only one page, mark 70b-70e pair, mark 7
0b-70g pair, mark 70c-70f pair, or mark 70c-70h pair, and in the case of a double-page spread film, it is detected by mark 70a-70d pair. According to the detection result, the Xθ table 36 is rotated by the θ angle, and the Xθ table 36 is moved in the X direction and the Y table 34 is moved in the Y direction by x, y so that the positions of the marks are aligned on the 4th plate. Make a match. This alignment amount θ, x, y
An example of how to obtain
No. 07, the detailed description will be omitted.

The operation of this embodiment will be described with reference to the flow charts shown in FIGS. First, in the tray unit 10,
A mount (base film) is set on the mount trays 18 and 20, and a color separation plate for one item is set on the film trays 14 and 16 in a predetermined order. The film tray is a size that can accommodate the largest size of film (two-page spread in the case of newspaper), and when only one page is set, the film is set on one side corresponding to the page of the tray.
When the operation start is instructed by operating a button, a switch, or the like, the upper table 60 moves down to the mount receiving position, and the pin 5 for positioning the mount from the Xθ table 36.
4 rises. After that, the mount tray 20 or 22 is inserted between the upper and lower tables.

When completely entered, as shown in FIG. 4 (a), the suction pad 62 descends from the upper table 60, and the pad vacuum device operates. Thereafter, the pins in the mount tray are lowered and buried in the tray to facilitate removal of the mount. As shown in FIG. 4B, the suction pad 62 moves up, and the table vacuum device of the upper table 60 operates. When the backing tray is retracted from between the upper and lower tables, as shown in FIG.
It is adsorbed to zero.

After that, the pins in the mount tray rise again and the upper table 60 descends to the mount passing position. The board transfer position is a position when the board is transferred from the upper table to the lower table. After stopping the operation of the table vacuum device of the upper table 60, the Xθ table 3
Reference numeral 6 reads an identification mark on the backing sheet and checks whether the front and back of the backing sheet and the backing sheet pattern are correct. If the result of the check is correct, the table vacuum of the Xθ table 36 is operated, and the upper table 60 is lowered to the lowest point to hold the mount on the Xθ table 36.
Thereafter, the upper table is raised to the film receiving position.
Thereby, the backing sheet is taken out from the backing tray and placed at a predetermined position on the Xθ table. The mounted backing sheet is sucked by the table vacuum device and fixed on the table.

When the negative tray 14 or 16 is inserted between the upper and lower tables, the color separation plate is taken out of the tray as shown in FIG. Adsorbed on the table 60. In addition, the size of the disassembled plate is 12 steps or 1 for the negative tray.
There is a function to identify whether it is a 5-step spread or whether it is a spread. Then, the upper table 60 descends to the positioning position. An optical sensor provided in the Xθ table 36 detects the film positioning mark 70, checks the film registration error, and determines the color separation plate positioning amounts θ, x, and y. In addition, it is also checked whether the color, front and back, pages, etc. of the separated plate are correct by the identification mark. If the check result is incorrect, a warning to that effect is given.

During positioning (registration), the pad vacuum device of the upper table 60 stops operating. By moving and rotating the Y table 34 and the Xθ table 36, the color separation plate is registered. Thereafter, the upper table 60 is lowered to the lowest point.

Since the table vacuum device of the Xθ table 36 is operating, the color separation plate is transferred from the upper table 60 to the mount on the Xθ table 36 by the operation.
The color separation plate is pressed down on the mount on the Xθ table 36. After that, the color separation plate is attached to the mount by the tape applying machine 64 incorporated in the upper table 60.

Then, the mount positioning pin 54 of the Xθ table 36 is lowered to be buried in the table, and the operation of the table vacuum device is stopped. At this time, since the upper table 60 is located at the lowest point, the upper table 6
By operating the pad vacuum device No. 0, it is possible to make the upper table 60 adsorb the backing sheet after being pasted. Then, the upper table 60 moves up to the plate ejection position, and the plate ejection tray 22 is inserted between the upper and lower tables. The lower table 30 is returned to the origin position.

After that, the table vacuum device of the upper table 60 is stopped, the suction pad is lowered, the pad vacuum is stopped, and then the suction pad is raised, so that the sheet after being stuck in the plate discharge tray 22 is mounted. To collect. The plate discharge tray 22 exits between the upper and lower tables, and the operation ends.

As described above, according to this embodiment, simply by setting the mount and the color separation plate in the tray, the mount and the film are automatically taken out from the tray and aligned on the lower table. The color separation plate can be pasted on the mount by the tape pasting machine which is placed and incorporated in the upper table, and the film can be pasted easily with high accuracy without burdening the operator.

The present invention is not limited to the above-described embodiments, but can be modified in various ways. For example, the mount may be directly placed on the lower table without being set in the tray. Further, although the decomposed plate is a negative film, it may be a positive film, and the object is a color photograph such as a newspaper. However, the present invention is not limited to this.
