Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables setting the enlargement/reduction ratio, position, and trimming of a plurality of original film images as specified on the layout paper, and displays them on a single film or raw material such as photographic paper. This invention relates to a composing camera whose purpose is to obtain a duplicate original by performing composing (collective) exposure on the images.

Traditionally, when photographers independently use film of various standard sizes and take photos under various shooting conditions and use a scanner to separate the colors as originals, the color balance and shooting ratio of the originals differ. Then, load multiple sheets into the scanner at once.
It is often difficult to disassemble them at the same time.

Therefore, in such a case, it becomes necessary to unify the color balance of the original and the original size. Therefore, in order to obtain a document with a uniform color balance and size, conventionally a puller is used, the enlarger's reduction/enlargement ratio is set to the ratio specified for the layout paper, and various filters are also used. Duplicate manuscripts were created by exposing images to film or photographic paper while maintaining a uniform color balance.

However, with this method, color balance, reduction,
The enlargement ratio will be as specified, but since it is difficult to set the exact exposure position and trimming specified on the layout paper, the scanner will reduce and enlarge it to the final original size for printing, resulting in color separation and halftone dots. The resulting negative or positive film is cut out one by one, aligned as specified on the layout paper, and trimmed, which is a very time-consuming process that requires special skills. It didn't happen.

There are some composing cameras on the market that use a computer to control position and trimming at the same time during duplication, but they take time to input data, are large, and expensive. In reality it is hardly used.

The present invention is a composing camera that eliminates the drawbacks of the composing camera described above and allows composing to be performed easily and in a short time.
When the film obtained according to the present invention is used as a manuscript and the magnification is specified to the final original size for printing using a scanner and color separation and dot-shape are performed, the resulting negative or positive film can be printed without pasting. It can now be used as a contact plate-making film for direct printing.

Hereinafter, the present invention will be explained in detail based on the drawings. FIG. 1 is an external front view of the composing camera of the present invention. FIG. 2 is a right side view of the composing camera of the present invention. Figure 3 shows the document holder 1 that holds the original film document.
FIG. 4 is a sectional view of the document holder 1. FIG. The document holder 1 has a structure in which a document is sandwiched from above and below by a transparent presser member 2 and fixed by a presser metal fitting 3. Figure 5 shows the document holder 1 in Figure 3.
FIG. For attachment to the document holder receiving frame built into the camera head section 4, the fixing screw 5 may be screwed through the fixing hole 6 into the screw hole 7 of the document holder receiving frame.

To select a desired film original from among the multiple film originals inserted into the original holder 1,
With the original holder 1 set in the original holder holder frame, move the entire original holder holder frame to the camera head section 4.
The camera head 4 is moved left and right by the action of the rack gear 8 within the frame, and the camera head 4 is inserted into the center position fixing hole 9 made at the position corresponding to the center of each document window.
A locking pin 10 is inserted from the outside and fixed at a desired position within the camera head 4. For color balance adjustment, when the film original is submitted, the required filter setting values are determined from a preset color balance adjustment list, and if necessary, the filter box 12 located at the bottom of the light source section 11 of the camera head section 4 is used. Add a CC filter to the image.
A color control head using an interference filter may be used instead of the CC filter.

FIG. 6 is an external perspective view of the imaging stand installed below the projection lens 13. FIG. 7 is a schematic top view of the monitor/photographing surface for explaining the horizontal rotation state of the monitor surface 14 and the photographing surface 15 on the photographing table, and FIG. 8 is a front sectional view of FIG. 7.

Holes for tweezers were made in the layout paper and raw photosensitive material, and the layout paper was placed on the monitor surface 14 and the photographic surface 15
In this step, the raw material is set by inserting the pin bar 16 into each hole, and is fixed by vacuum suction from the vacuum hole 17 connected to a vacuum pump. In this case, instead of the pin bar 16, an L-shaped corner plate or the like may be used for positioning. Since the raw photosensitive material is normally shielded from light by the light shielding cover 18, the room where the composing camera is installed can be operated in a bright room except when the raw photosensitive material is set and exposed.

When photographing, the exposure lamp of the light source section 11 is turned on and the film image of the film document is displayed on the monitor surface 1.
4 onto the layout sheet vacuum-fixed,
The pattern must match the exposure position and enlargement/reduction ratio specified on the layout sheet.

In this case, since the document holder receiving frame is fixed by the locking pin 10, it is difficult to adjust the exposure position by moving the film document. Therefore, in the present invention, the X-direction positioning table 19, on which the monitor surface 14 and the photographing surface 15 are mounted, and the The Y-direction positioning table 20 is moved in the X and Y directions so that the projected picture and the picture center of the layout paper on the monitor surface 14 can be aligned.

If there is an angular misalignment of the pattern on the layout sheet with respect to the projected image, rotate the monitor surface 14 or rotation interlocking gear 21 left and right manually or by motor drive, etc. to instruct the pattern angle on the layout sheet. It is possible to match the angle of the picture.

The monitor surface 14 and the photographing surface 15 are mounted on the same surface, and when the monitor surface 14 rotates left and right, the photographing surface 15 also rotates in the same direction and by the same angle by the rotation interlocking gear 21, so that both do the same movement. In this way, the exposure position is determined,
Lock the X/Y rotation movement mechanism to a fixed state.

Adjustment of the enlargement/reduction ratio can be carried out by moving the entire camera head section 4, including the light source section 11, projection lens 13, etc., up and down to match the size of the projected image with the layout paper pattern, and focusing is done using the projection lens. All you have to do is move 13 up and down.

The camera head 4 can be moved up and down by operating the magnification adjustment handle 22, and the focus can be adjusted by operating the focus adjustment handle 23.

If trimming and alignment of the projected image are required, masking is performed using the masking device shown in FIG. 9.

FIG. 10 is a sectional view of the mask device.

In this mask device, the positioning pins 25 protruding from the lower part of the mask holding plate 24 are attached to the monitor surface 1.
By inserting the mask device into the pin receiving hole 26 provided in the photographing surface 15 and 4, the mask device can be always set in a fixed position.Even if the monitor surface 14 is rotated, the mask device also rotates, and the photographing surface 15 is also Since it rotates, when the positioning pin 25 of the mask device is inserted into the pin receiving hole 26 on the imaging surface 15, the monitor surface 1
The masking positional relationship set in step 4 can be reproduced as is on the imaging surface 15.

To mask, attach the mask light shielding plate 2 according to the masking instructions on the layout sheet.
This is done by moving 7, 28, 29, and 30. The mask light-shielding plates 27, 28, 29, and 30 move independently in parallel in the X and Y directions along the mask light-shielding plate movement grooves 31 and 32 to construct a mask of any size. . Through the steps described above, color balance, enlargement/reduction ratio on the monitor surface 14, exposure position, and masking settings are completed. Next, the mask device is moved to the photographing surface 15 using a cylindrical mask device suction arm 34 mounted on the camera stand 33. In this embodiment, the mask device suction arm 34 has a magnetic head 35 at its tip that can turn on and off the magnetic force by turning on and off the current, and by operating the lifting lever 36 of the mask device moving means, The magnetic head 35 is brought into contact with and attracted to the mask holding plate 24, and can be lifted while maintaining the masking positional relationship set in the above step. Further, this mask device suction arm 34 is
Directional positioning table 19 and Y direction positioning table 20
The structure is such that the suction arm can be moved to an arbitrary position and fixed by means of an X-direction moving rail 37 and a Y-direction moving rail 38 so as to follow the movement of the suction arm.

To actually perform the work, proceed as follows. First, the mask device suction arm 34 is moved and fixed onto the mask holding plate 24, and the elevating lever 36 is

Monitor/exposure switching table 3
After the movement and fixation of 9 is completed, lift lever 36
If the mask device suction arm 34 is lowered at
Positioning pin 25 at the bottom of the mask holding plate 24
is inserted into the pin receiving hole 26 provided in the photographing surface 15 to reproduce the masking state set on the monitor surface 14 on the photographing surface 15. Next, exposure is performed by turning on the exposure lamp of the light source section 11 for a predetermined exposure time or by opening the shutter.

This completes the exposure work including masking of the first surface.

To perform exposure work on the second surface, lift lever 3
At step 6, raise the mask device suction arm 34 that suctions the mask holding plate 24, release the fixation of the monitor/exposure switching table 39, and remove the stopper 42 at the right end.
The positioning pin 25 is positioned directly above the pin receiving hole 26 of the monitor surface 14 by moving and fixing the monitor surface 14 and the photographing surface 15 in the direction corresponding to the separation distance between the respective centers of rotation. Then, when the mask holding plate 24 is lowered using the lift lever 36, the pins 25 are inserted into the pin receiving holes 26 of the monitor surface 14. Next, the light shielding cover 18 is placed over the raw photosensitive material to block light, and the room is made into a bright room, so that the locking pin 10 of the document holder receiving frame is closed.
is pulled out, the film original held in the next original holder 1 is brought under the exposure lamp of the light source section 11 using the rack gear 8, the image of the film original is projected onto the layout paper, and the image is fixed with the locking pin 10. do. Next, color balance adjustment, exposure position adjustment according to the pattern of the layout paper, enlargement/reduction ratio adjustment, focus adjustment, masking operation, monitor exposure switching table 39
Operations such as movement are required, but these can be performed using the same operating procedures as those performed during the exposure of the first surface described above. The same operating procedure is followed when performing composing exposure on the third and fourth surfaces.

When the exposure of the final surface is completed, the vacuum pump is stopped in a dark room, and the raw photosensitive material that has been exposed for compositing is taken out from above the imaging surface 15, developed, and retouched if necessary, and then transferred to a scanner. If the film is reduced or enlarged to the required size and subjected to color separation and halftone cutting, the resulting negative or positive film can be used as is as a halftone film for contact platemaking.

Although the present invention has been described in detail above, the present invention is not limited thereto. Based on the input information, the X and Y directions of the mask light shielding plates 27, 28, 29, and 30 of the mask device installed on the photographing surface 15 are directly controlled, and masking is performed on the raw material. You can. When this method is used, there is no movement of the mask device from the monitor surface 14 to the imaging surface 15, so the number of work steps is reduced and work efficiency can be improved.

In addition, by moving the cursor to the required position of the pattern on the layout sheet set on the monitor surface 14, the distance traveled can be digitally displayed, and based on the digital display, the mask of the mask device installed on the photographing surface 15 is adjusted.
