Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention synthesizes a main image recorded on a photographic film and an illustration image such as a character, a picture, or a computer graphic (CG) in the same frame. The present invention relates to a photosynthesis printing apparatus for performing.

[Conventional technology]

Recently, as a postcard, a synthetic print photograph in which an image of a person or the like is printed as a main image on a color photographic paper (color paper) and an illustration image such as a greeting is printed adjacent to the image is widely used.

In this composite print photograph, it is necessary to separately print the main image and the illustration image due to the difference in the printing exposure condition between the main image and the illustration image, and therefore, for example, the illustration image printing exposure section and the main image printing exposure section are used as the photosensitive material transfer section. They are installed side by side. An illustration image lith film having an illustration image is set in the illustration image printing exposure unit, and a main image negative film having a main image is set in the main image printing exposure unit.

[Problems to be solved by the invention]

There are several types of postcards based on recent composite print photographs depending on the position and size of the illustration image, and the user can select the desired one from these. Therefore, it is necessary to change the printing magnification of the main image and the size of the mask in correspondence with the illustration image depending on the type of postcard. Further, when the print size of the main image changes, it is necessary to correct the exposure amount correspondingly.

However, conventionally, the printing exposure condition of the main image is manually set according to the pattern of the illustration image. Since this setting is complicated, mistakes in setting or forgetting of settings are likely to occur, and if mistakes in setting occur, proper composite print cannot be obtained.
Moreover, there is a problem that the efficiency cannot be improved because the setting is done manually.

The present invention is to solve the above problems, and accurately and quickly sets the printing exposure condition of the main image even when the composite pattern of the illustration image and the main image is changed in the composite print photograph such as a postcard. It is an object of the present invention to provide a photosynthesis printing apparatus capable of performing.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention is recorded on an illustration image film or a holder holding this film, and is arranged in an identification signal section for identifying the type of a composite pattern and an illustration image printing exposure section, and A signal reading unit for reading the identification signal unit and a control unit for setting the main image printing exposure unit to the main image printing exposure condition of the main image corresponding to the illustration image based on the signal output from the signal reading unit. is there.

[Action]

When the illustration image film is set in the illustration image printing / exposing section, the identification signal section of the illustration image film is read. Then, based on the read identification data, the printing exposure condition of the main image to be combined with the illustration image is obtained. With respect to this printing exposure condition, the printing exposure condition of the corresponding main image is searched using the identification data as the search data, so that the printing exposure condition of the main image corresponding to the illustration image can be obtained quickly and accurately without human intervention. Based on this printing exposure condition, the opening size and position of the main image mask are adjusted corresponding to the set illustration image, and the data of the printing magnification is sent to the exposure amount calculation unit to calculate the appropriate exposure amount. It will be possible.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 10 is a color paper, which is wound into a roll and stored in a magazine 11.
The color paper 10 is set at the print position 15 of the illustration image and the print position 16 of the main image by the pair of conveying rollers 13 and 14. At each printing position 15 and 16, a pressure plate 17 and a paper mask 18 for holding the color paper 10 flat are provided. An illustration image printing exposure unit 20 and a main image printing exposure unit 21 are provided below each print position. Further, a loop forming stage 22 for temporarily storing the color paper 10 on which the illustration image has been exposed and exposed in a loop shape is provided between the printing positions 15 and 16. The loop forming stage 22 is provided with a movable guide plate 23 for guiding the front end of the color paper 10 to the pair of transport rollers 14 of the main image printing exposure section 21. The movable guide plate 23 is swingably attached to the shaft of the lower roller of the conveying roller pair 13 of the illustration image printing / exposure unit 21, is horizontal when guiding the leading edge of the color paper, and rotates downward when forming a loop. Will be retracted.

The illustration image printing / exposure unit 20 is configured as follows. The white light from the light source 25 is sufficiently diffused by the diffusion box 26, and then the illustration film 28 on the board holder 27.
Illuminate. The diffusion box 26 has a diffusion plate attached to both ends of a rectangular tube whose inner surface is a mirror surface, and diffuses the printing light sufficiently. An illustration image such as characters and pictures recorded on the lith film 28 is imaged on the color paper 10 at the print position by the printing lens 29. A shutter 30 is provided between the printing lens 29 and the color paper 10 to control the exposure time so as to obtain a predetermined exposure amount. The shutter 30 is driven by a shutter drive unit 31. Also,
On the color paper entry side of print position 15, a notch as a frame position mark is set on color paper 10 to accurately set the frame on which the illustration image is printed and exposed at this print position to the print position of the next main image. A notch 32 for opening is provided. Instead of the notcher 32, a pinhole may be formed or a mark may be recorded.

As shown in FIG. 2, the lith film 28 for illustration images
Is attached to the frame 33 as a film holder,
This forms the illustration image printing board 34. The illustration image printing board 34 is detachably attached to the board holder 27. Board holder 27 is the holder body
36, and a board retainer 37 which cooperates with this and holds the illustration image printing board 34 therebetween. Holder body
A mounting groove 38 into which the illustration image printing board 34 is fitted is provided in 36.

The illustration image lith film 28 is configured by arranging a mask portion 40 for vertically forming a main image exposure area in the central portion of the screen and arranging illustration images 41 on both sides thereof. In addition to this, a plurality of patterns in which the combined pattern of the illustration image and the main image is changed are prepared. Third example of this
Shown in the figure. FIG. 3A shows an illustration image printing exposure board 44 in which a mask portion 42 for vertically forming a main image exposure area is vertically arranged on the right side of the screen and an illustration image 43 is arranged on the left side thereof.
FIG. 2B shows a mask portion 46 for forming a rectangular main image exposure area in the central portion of the screen.
3 shows an illustration image printing board 48 around which an illustration image 47 is arranged.

The illustration image lith film 28 can be easily created by photographing a document with a lithographic negative and then developing the photograph. In this lith film, when a document written in black on a white background is photographed, white characters in which character portions are transparent are recorded. When a document is photographed in which the character portion is white and the surroundings are black, a lith film in which the portions other than the character are transparent can be obtained. When recording colored characters on color paper, it is only necessary to use a lithographic film in which the characters are transparent and adjust the ratio of the three-color exposure amount. Instead of the lith film, a transparent or opaque plastic sheet or the like may be used, and characters may be printed or punched on this. In addition to characters, pictures, CG, etc. can also be recorded on the lith film 28. The mask portions 40, 42, and 46 can be simultaneously recorded together with the characters when the lith film is formed, or can be formed by extending the frame 33 or stacking the mask member on the lithographic negative.

At a position close to the corner of the frame 33, an identification signal section 50 for identifying the type of the combined pattern of the illustration image printing board 34 and the main image is provided. Identification signal section 50
Is configured by arranging a plurality of light-shielding portions 51 and light-transmitting holes 52 in parallel, and identifies the types of composite patterns of various baking boats by permuting the presence or absence of light-shielding or light-transmitting. The identification signal section 50
Can be formed by cutting out a part of the frame 33, or can be recorded as an optical mark on the surface of the frame 33 by coating or printing. Further, it may be composed of a non-conductive part of a conductive part like a DX code of Patrone.

The board holder 27 includes an illustration image printing board 3
A signal portion reading sensor 54 for detecting the identification signal portion 50 when the 4, 44 and 48 are attached is provided. The signal section reading sensor 54 is for detecting the presence or absence of light shielding to identify the type of composite pattern of the illustration image printing board. This signal reading sensor 54
A transmissive sensor is used, but a reflective sensor may be used instead. In this case, marks having different reflectances, such as white or black, are layered on the surface of the frame 33. Further, the illustration image printing board can be identified by using a switch that is mechanically turned on instead of the optical sensor.

The main image printing exposure unit 21 shown in FIG. 1 is configured as follows. White light emitted from the light source 60 passes through a cyan filter 61, a magenta filter 62, a yellow filter 63, and then enters a diffusion box 64. The filters 61 to 63 of the respective colors are adjusted in the amount of insertion into the printing optical path 66 by the filter adjusting unit 65, and the light quality of the printing light is adjusted.

The printing light diffused by the diffusion box 64 illuminates the negative film 68 set on the film carrier 67. The film carrier 67 is composed of a carrier base 70 and a negative retainer 71 that holds the negative film 68 in cooperation with the carrier base 70. The negative retainer 71 is configured to be pressed against the negative film 68 to ensure its flatness during exposure of the main image by a spring material or the like, and when the negative film 68 is moved,
It is designed to release the pressure contact.

A variable mask 73 for printing and exposing the main image at a predetermined position on the color paper 10 is arranged above the negative press 71. The variable mask 73 is for printing and exposing the main image on the main image print area (the area where the mask portion of the illustration image printing board is projected on the color paper) of the color paper on which the illustration image is printed and exposed. As shown in FIG. 4, this variable mask 73 has mask main bodies 75 to 78 arranged on four sides of a rectangular mask opening 74, and the mask main bodies 75 to 78 can be moved in parallel by a shift means 80. It is said that. The shift means 80 is controlled by a controller 94, which will be described later, and moves in parallel to each of the mask main bodies 75 to 78 to change the position and the size of the mask opening 74 in accordance with the mask portion of the illustration image printing board. .

As shown in FIGS. 1 and 4, a zoom lens 81 for forming a main image on the color paper 10 is arranged between the variable mask 73 and the color paper 10. The zoom lens 81 is driven by the focal length adjusting means 82 to form a main image on the color paper 10 at an optimum printing magnification.

A shutter 84 is arranged in the printing optical path 66 between the print position 16 of the main image and the zoom lens 81, and is controlled by the shutter drive unit 85 so that a predetermined exposure amount is obtained.
A knock sensor 87 is provided on the color paper entry side of the print position 16. Based on the notch detection signal of the notch sensor 87, the controller 94, which will be described later, controls the rotation of the conveying roller pair 14 to accurately set the frame on which the illustration image has been printed and exposed at the print position 16.

A light receiver 89 is arranged diagonally above the film carrier 67. This light receiver 89 includes a lens 90 and a light receiving sensor 91.
It measures the average transmitted light of the main image. This photometric value is converted into a density value by the logarithmic conversion unit 92 and then sent to the controller 94.

The controller 94 identifies the type of the illustration image printing board 34 set in the board holder 27 based on the signal from the signal reading sensor 54, and obtains the printing magnification of the main image according to the identification data. Since the relationship between the printing magnification and the magnification balance value is stored in ROM95, this ROM
Using the magnification balance value M _i (i represents one of B, G, and R) read from 95 and the average transmission density value D _i output from the logarithmic conversion unit 92, The exposure amount E _i is calculated, and the filter adjustment unit 65 is controlled based on this.

log E _i = α _i × (D _i −D N _i ) + M _i + β _i DN _i : Normal control negative density value D _i : Main image density value to be printed α _i : Coefficient β _i : Constant This controller 94 It is composed of a well-known microcomputer, and controls each part based on various data stored in the RAM 96 and detection signals from various sensors by a program stored in a built-in ROM 95.

The RAM 96 stores optimum printing exposure conditions for printing the main image for each type of composite pattern. The printing exposure conditions are: the opening size and opening position data of the variable mask for printing the main image onto the main image print area that has been printed with the illustration image, and the main image is displayed when the mask opening is set by this data. There are magnification balance values M _i for printing and exposing the main image print area at an appropriate density, and focal length data of a zoom lens for printing and exposing the main image on the main image print area at an optimum magnification. It is recorded in the print channel format. The print channel stores the respective data of the printing exposure conditions for each kind of composite pattern, using the identification number obtained by reading the identification signal 50 as search data. In addition, each of the above data is an illustration image printing board
It is obtained in advance for each type of 34, 44, and 48 composite patterns.

A keyboard 97 is connected to the controller 94. The keyboard 97 is provided with a print key 98 that is operated when starting printing, a numeric key 99 for designating the number of prints, and other control keys.

 Next, the operation of this embodiment will be described.

First, the illustration image baking board 34 is attached to the board holder 27.
Then, the main image negative films 68 are set on the film carriers 67, respectively. After this, the numeric keys on keyboard 97
Operate 99 to enter the number of prints. Then, by operating the print key 98, the controller 94 changes the identification signal section 50 of the illustration image printing board 34 to the signal section reading sensor.
Read by 54.

In the controller 94, as shown in FIG. 5, the signal from the signal section reading sensor 54 is first decoded by the decoder 100 to obtain an identification signal. Next, the search circuit 101 searches the print channel corresponding to this identification number from the RAM 96 by using the identification number as search data, and controls each part based on the printing exposure condition obtained from this print channel. That is, the variable mask 73 is driven via the shift means 80 and the zoom lens 81 is driven by the focal length adjusting means 82 based on the printing exposure condition. This makes it possible to print the main image at an accurate position and at an appropriate printing magnification in an area corresponding to the mask portion of the illustration image.

In this state, the controller 94 prints and exposes the illustration image with the illustration image printing and exposure section 20. First, the unexposed color paper 10 is set at the print position by the transport roller 13, and then the color paper 10 is set by the notcher 32.
Make a notch on the side edge of the. After that, printing exposure of the illustration image is performed. In the same manner, printing exposure of the illustration images for the number of prints is performed.

Next, the controller 94 stores the color paper 10 on which the illustration image has been printed and exposed on the loop forming stage 22 for a predetermined length, and thereafter sets the color paper 10 at the print position 16 of the main image. Since this setting is performed based on the notch, the frame on which the illustration image has been printed and exposed is accurately set at the main image print position 16.

After setting this color paper 10, the controller 94
Activates the light receiver 91 to obtain the average transmission density D _i . The exposure amount calculation unit of the controller 94 calculates the optimum exposure amount at the time of main image printing exposure from the magnification balance value M _i and the density value D _i, and controls the filter adjustment unit 65 based on this. In addition,
If the filter adjustment unit 65 cannot correct the
Controls the opening time of 84. In this way, since the shutter 84 is opened for a predetermined time after the dimming of the printing light, the main image is printed and exposed on the frame on which the illustration image is printed and exposed.
The illustration image and the main image can be combined and printed.
The color paper 10 that has been synthetically baked is taken up by the take-up reel 12 and then developed by a processor (not shown) and cut into each frame.

When a new main image is to be printed and exposed while keeping the illustration image as it is, the negative film 68 for the new main image is set on the film carrier 67 and the number of copies is designated by the keyboard 97. In this case,
Since the aperture position and size of the variable max 73 and the focal length of the zoom lens 81 have already been adjusted in correspondence with the illustration image printing board, each point of the main image newly set by the light receiver 89 is set. All you have to do is measure the light. Then, this photometric value and the magnification balance value previously searched and used
With M _i , an appropriate exposure amount is calculated according to the newly set main image, and the main image is subjected to printing exposure based on this.

When the illustration image is also changed, the desired illustration image printing board is set in the board holder 27 and the negative film 68 for the main image is set in the film carrier 67. Then, after setting the desired number of prints, by operating the print key 98, in the same manner as described above, the optimum printing exposure condition of the main image is set according to the composite pattern of the set illustration image printing board. It
Therefore, a print photograph of a new composite pattern can be created with an appropriate exposure amount.

In the above example, the print position of the illustration image
A loop forming stage 22 for temporarily storing the color image 10 on which the illustration image has been printed and exposed is provided between 15 and the print position 16 of the main image, and the illustration image and the main image 2
Although the two exposures are performed independently, if the color paper 10 is fed by a predetermined pitch according to the interval between these two print positions and the frame size, and the printing exposure is performed alternately, the loop forming stage is omitted. You can also

Further, in the above-mentioned embodiment, the change of the printing magnification is performed by using the zoom lens 81, but instead of this, a lens turret can be used. In this case, the lens balance value is automatically set according to the lens used.

Further, in the above embodiment, the identification signal section 50 is
Although it is formed in the frame 33 that holds 28, instead of this, it may be formed in a blank portion of the lith film on which the illustration image is recorded and which does not affect the illustration image.

As the negative film 68, in addition to the 135 type full size, 135 type half size, 110 size, 12
6 sizes and the like can be used. When using a negative film other than the 135 type full size,
The film size is entered from the keyboard. And
The printing magnification is determined in consideration of this film size.
