Abstract

PURPOSE:To quickly realize composite printing in order to form a composite picture by leaving a printing object existing on an optical axis on the axis as it is when both printing objects are printed in the same printing position on a photosensitive material, moving the photosensitive material only, and then arranging the subsequent printing position on the optical axis. CONSTITUTION:Composite printing method is such that first and second printing objects 14 and 16 are alternately arranged onto the optical axis, and composed and printed in the same printing position on the photosensitive material 12; under the condition where both printing objects are printed in the same place on the photosensitive material 12, the photosensitive material 12 is moved with the printing object on the optical axis while arranging the object on the optical axis, the following printing position is arranged on the optical axis, and printing for the subsequent position is started from the printing object arranged on the optical axis as it is. When the first and second printing objects are printed in the same printing position on the photosensitive material, only one operation to alter a conjugate length is required, therefore, efficient printing is carried out in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composite printing method for combining and printing different printing objects at the same printing position on a photosensitive material.

[Background technology]

A composite image can be obtained by combining an image and text and printing them at the same printing position on a photosensitive material.

In many cases, the composite image is printed by alternately placing a lithographic film having characters and a negative film having an image at the printing position. In this case, for example, after printing the image, printing the characters, and completing the composite printing, place the negative film on the printing optical axis to print the image again, and in this state shift the photographic paper to expose the next printing position. Place it on the axis. Therefore, the image is always printed on photographic paper first, followed by the text. Similarly, when printing letters for the first time, the letters are always printed first at different printing positions on the photographic paper.

Therefore, if the printing magnification of the image and the printing magnification of the text are different, it is necessary to move the optical means in the optical axis direction and change the conjugate length twice for one composite image, for the image and the text. Become. Therefore, the operation time required for this purpose becomes a hindrance to efficient image printing.

The present invention takes the above-mentioned facts into account, and provides a composite printing method that enables quick composite printing when performing composite printing for forming a composite image by printing multiple printing targets together at the same printing position on a photosensitive material. That is the purpose.

[Summary and operation of the invention]

In the present invention, a first printing object and a second printing object are arranged alternately on the optical axis, and both the first and second printing objects are combined and printed at the same printing position on a photosensitive material. This is a composite printing method in which both objects are printed at the same position on the photosensitive material, and then the photosensitive material is moved while the object on the optical axis remains on the optical axis to determine the next printing position. It is arranged on the optical axis, and the printing to the printing position of the above method is characterized in that the printing target that remains arranged on the optical axis is printed first.

In this way, in the present invention, when both printing objects are printed at the same position on the photosensitive material, the printing object on the optical axis remains on the optical axis, and only the photosensitive material is moved to the next printing position. is placed on the optical axis. When printing to the next printing position, the printing target placed on the optical axis is printed first. Therefore, the order in which composite images are printed at adjacent printing positions on the photosensitive material is different. In other words, at the first printing position, the first printing object is printed first and then the second printing object is printed, and at the second printing position, the second printing object is printed and then the first printing object is printed. is burned. Therefore, when printing the first and second printing objects at the same printing position on a photosensitive material, only one conjugate length change operation is required for printing the first or second printing object, and it is a short process. Efficient printing is possible in less time.

[Embodiments of the invention]

FIG. 1 shows a schematic diagram for forming a composite image according to the present invention. That is, photographic paper 12 which is a photosensitive material

A roller 48 is pivotally supported on the movable table 34 on the opposite side of the end to which the bracket 44 is attached, and the outer periphery of this roller 48 is in contact with the top of the base plate 32.

Further, an arm 52 protrudes from the movable table 34 between the pair of brackets 440 and is fixed to a part of the drive timing belt 54. This drive timing belt 54
is wound around pulleys 56 and 58 which are supported with their axes perpendicular to the base plate 32, so that a straight line is formed between them, and the arm 52 is fixed to a part of this straight line.

The pulley 56 is connected to the motor 6 disposed on the base plate 32.
When the motor 62 rotates, the drive timing belt 54 is moved in the longitudinal direction, and the movable table 34 is reciprocated in the direction of arrow A. It is now possible to do so.

A baking opening 84 is formed in each of the lower mask and upper mask, and suppressing glasses 83 and 85 are attached to each (pressing glass 83 of the lower mask 74).
(not shown) are arranged coaxially with the burning openings 66 and 67, respectively. In the state shown in FIG. 2.3, the lower mask 74 and the upper mask 78 are aligned with the optical axis, but when the moving stage 34 is moved toward the lower left of FIG. 2 in the direction of the arrow, the lower mask 76 and the upper mask 82 The printing aperture 84 is aligned with the optical axis.

A guide plate 94 is fixed to the base plate 32 through vertical pins 92 and 93 in parallel with the base plate 32, and covers the movable table 34. Handles 95 and 96 are fixed to the guide plate 94 near the upright pins 92 and 93 for gripping by an operator, and the center portion is attached to the base plate 9.
The lower part 94A is closer to the base plate 3 than the higher part 94B near which the handle 95.96 is fixed.
It is approaching 2. This lower portion 94A is designed not to interfere with the light diffusion box B (FIG. 8) when the base plate 32 is mounted on the printing apparatus P (FIG. 7). A firing opening 98 is also formed in this lower portion 94A and is coaxial with the firing opening of the base plate 32.

As shown in Fig. 4.5, the lower mask 74.76 has a rectangular shape, and is mounted in the recess 68.72 of the moving table 34 in the mounting state shown in Fig. 2.3 and in a state rotated 90 degrees around the vertical axis. It is possible.

Upper masks 78 and 82 are pivotally supported on the lower masks 74 and 76 via shafts 102, and are rotatable until the pressing glasses 83 and 85 are in close contact with each other and the object to be printed, such as a film, is sandwiched between them. It has become. On the opposite side of the shaft 102 there is a locking arm 10 from the upper mask 78.82.
4 protrudes and corresponds to the locking pin 106 supported by the lower mask 74, 76. This locking pin 106 has small diameter portions 106A at both ends pivotally supported by elongated holes 108A of a bracket 108 fixed to the lower mask 74, 76.
It is biased toward the locking arm 104 by a tension coil spring 110 .

At the distal end of the locking arm 104 in contact with the locking bottle 106, there is a bent portion 104 having a substantially V-shaped cross section as shown in FIG.
A is formed, and an inclined portion 104B on the locking arm 104 side of this bent portion 104A is inclined at an angle of about 45 degrees with respect to the locking arm 104, and is used for receiving a locking bottle 106. .

Therefore, the upper mask is 78.82 and the lower mask is 74.7.
6, the tension coil spring 110 causes the locking bottle 106 to ride up on this inclined portion 104B, and the upper mask 7
8.82 is brought into close contact with the lower mask 74.76. In this way, the locking pin 106 and the inclined portion 104
B means upper mask 78.82 and lower mask 74.76
It has an extremely thin latch structure to keep the two in close contact with each other. As a result, even if the moving table 34 is moved in the direction indicated by the arrow in FIG.
It is designed not to interfere with A.

From the lower mask 74, support plates 112.
114 is protruded to support the end of the film having the image frame following the negative film where the printing frame is placed into the printing aperture 84.

The support plate 112 has a curled portion 112A at its tip, and is configured to accommodate the film end portion in a bent state. This curled portion 112A does not reach below the guide plate 94 even when the movable table 34 is moved in the direction of arrow A, so it does not interfere with the guide plate 94, but the support plate 114
It has a flat plate shape so that it can fit between the movable table 34 and the movable table 34. The upper mask 78 also has these support plates 112.
Support-like support plates 116 and 118 corresponding to 114 are extended to serve as film holders, and can also be inserted under the guide plate lower portion 94A.

Note that the lower mask 74 and upper mask 78 are rotated 90 degrees around the vertical axis, and the lower mask and upper mask (see the imaginary line in FIG. 3) for loading the negative film are as shown by the imaginary line in FIG. 4. A curled portion 114A may be provided at the tip of the support plate 114, and this curled portion 114A moves below the guide plate 94 when the movable table 34 is moved, but does not enter below the lower portion 94A and moves toward the higher portion 94B. There is no interference as it enters downward. In this case, the support plate 118 has a short dimension as shown in phantom lines in FIG.

As shown in FIG. 4.5, in the recess 68.72 there is a positioning block 122 for the lower mask 74.76, and a holding plate spring 1.
24 are provided.

Further, as shown in FIG. 4.5, a gripping plate 126 is integrally extended and erected from the bracket 108, and is used for gripping when loading and unloading the upper mask 78, 82 and lower mask 74, 76 onto the moving table 34. ing.

Note that the lower mask 76 and the upper mask 78 are attached to the support plates 112 and 11 like the lower mask 74 and the upper mask 78.
4. Since there is no 118 or curled portion 112A, and the illustrated characters to be clamped have a relatively small area, it is thin and compact, and even if it is in the illustrated state in FIG. It can easily enter below the portion 94A.

Next, FIG. 8 shows a printing device P on which a base plate 32 is mounted. In this printing device P, the housing 2
A negative carrier 216 shown in FIG. 9 is mounted on the base plate 214 of the present embodiment.
can be installed. A light diffusing cylinder B is suspended above the base plate 214, and the light from the light source 220 is reflected by the mirror 221A and then passed through the printing object to the optical means 22.
4, the photographic paper 12 is exposed to light.

As shown in FIG. 9, openings 262 are provided in the base plate 214 at the four corners of the printing opening 260, and positioning protrusions 268 and 270 can be inserted into the base plate 214 from the directions of arrows B' and C, which are perpendicular to each other. It is possible to position it. However, these positioning protrusions 2
68.270 is the base play when shooting with trimming) 2
14 so that the negative carrier 216 can be moved to an arbitrary position.

As shown in FIG. 6, the base plate 32 has grooves 132 and 134 formed on the back surface of the base plate 1-21.
Positioning protrusions 268 and 270 protruding above 4 can be received for positioning.

As shown in FIG. 8, the negative carrier 216 is pressed and fixed to the base plate 214 by a plate 350 pushed down by a compression coil spring 352. This plate 350 is adapted to press down on the lower portion 94A when the base plate 32 is mounted on the base plate 214.

Next, the operation of this embodiment will be explained.

In the state shown in FIG. 8, since the negative carrier 216 is mounted, only the image is printed and the positioning projections 268, 27
By descending to 0, cropping photography is possible.

When printing a composite image, the negative carrier 216 is removed from the base plate 214, and the positioning protrusions 268 and 270 are removed.
Insert the base plate 32 onto the base plate 214 in the lower left direction in FIG. 2 with the protruding state. Positioning protrusion 2
68.270 engages the grooves 132.134, and the plate 350 of the printing device P is inserted into the printing opening 9 of the lower portion 94A.
Position the base plate 32 by pressing down both sides of the base plate 80. Although the light diffusion box B hangs down near the baking opening 98,
There is no interference due to the presence of the lower portion 94A.

Lower mask 74, upper mask 78 and lower mask 76
A negative film, which is the first object to be printed, and a lithium film, which is the second object to be printed, are sandwiched between the upper mask 82 and the upper mask 82, respectively.

In the state shown in FIG. 2.3, since the negative film is placed on the printing optical axis, the photographic image on the negative film is first printed at the first printing position on the photographic paper. Here, while driving the motor 62 to move the movable table 34 in the direction of arrow A (lower left direction in FIG. 2), illustration characters are printed on the lithographic film held between the lower mask 76 and the upper mask 82 to create a composite image. to form.

Here, while the lithographic film held between the lower mask 76 and the upper mask 82 is placed along the optical axis, the photographic paper is driven to place the second printing position on the optical axis. In this state, the illustrated characters are printed onto photographic paper using a lithium film placed on the optical axis.

Further, by driving the motor 62 in the opposite direction, the lower mask 74,
A negative film on which a photographic image is formed, which is held between the upper masks 78, is placed along the optical axis and printed onto photographic paper. The illustrated characters sandwiched between the lower mask 76 and the upper mask 82 are arranged on the optical axis by roughly driving the motor 62. As a result, the illustrated characters are first printed at the second printing position, and then the photographic image is printed, thereby forming a composite image.

Here, the photographic paper is driven while the lithographic film on which illustrated characters are formed is placed along the front axis, so that the third printing position is placed along the optical axis. Therefore, at the third printing position, the illustration characters on the lithographic film are first printed, and then the moving table 34 is driven to place the negative film on which the photographic image has been printed along the optical axis, and the photographic image is printed.

Thereafter, operations similar to those described above are sequentially performed to form a plurality of composite images on the photographic paper.

Even during such movement of the movable table 34, the high portion 94B of the guide plate 94 accommodates the curled portions 112A, 114A, ensuring smooth movement of the movable table 34.

Although the above embodiment describes a composite image using a negative film and a lithographic film, the present invention is not limited to this, and can be applied to any method in which different printing targets are compositely printed at the same printing position on a photosensitive material. It is.

〔Effect of the invention〕

Since the present invention employs the above-described method, there is little movement of the optical system to change the conjugate length at the same printing position, and it has the excellent effect of enabling rapid printing.
