[0027]

Embodiments of the present invention will be described with reference to the drawings, including the operation thereof. First, the outline of CRT printing (printing) will be described.

As shown in the system configuration diagram of FIG. 7, a negative image, a reversal image, and a reflection original (color print, color copy, character original, etc.) image is input in the image input section.

For inputting a negative image, digital data such as a photo CD (PCD) can be read in addition to the image taken in through a scanner.

The input image is processed and image-processed by the image processing unit in accordance with a desired printing format.

The main functions of the processing unit are as follows.

Image enlargement, reduction, trimming, layout Text, illustration composition Image brightness, contrast adjustment, color correction Image resolution correction, enhancement function (scene composition, blur correction, edge enhancement, etc.) B / W Image Creation These processes are performed by a user operation or each standard processing algorithm prepared in advance, and at the same time, the process and results are displayed on the image display unit. The operator can add the necessary image processing operation interactively on the operation unit while checking the CRT screen on the display unit.

The finally processed image is displayed on the color CRT of the image output section, and the display image is optically exposed on the photographic paper.

Necessary exposure conditions (projection magnification, number of exposures, print size for printing, etc.) are input through the operation unit, and the control unit performs sequence control of each unit according to the conditions.

When docking with a minilab system for exposing and printing photographic film images, the image output unit (CRT)
It is also possible to connect the exposure unit, the paper transport unit, etc.) to the minilab, and to configure the image input unit, the image processing unit, the image display unit, etc. separately from the minilab connection unit to perform information processing online or offline. .

Next, the side sectional view of FIG. 1 shows an example of a minilab printer and a paper photographic paper developing system when a CRT exposure unit, which is a part of the construction of the photographic printing apparatus of the present invention, is not mounted.

A photosensitive material such as roll printing paper preset in the magazine 1 (hereinafter simply referred to as printing paper or color paper) (the magazine is exchanged depending on the paper width used) is a sub unit of the printer unit main body (film image exposure unit) 50A. It is pulled out from the magazine by the drive roller 16. The amount of withdrawal from the magazine 1 is managed according to the print size specified in advance (in this example, a pulse motor is used)
When a predetermined amount (one print) is fed, the cutter 17 operates and the photographic paper is cut. The cut photographic paper is sent to the belt carrying unit 19 by the first roller 18. The belt transport unit moves to the exposure position and waits while being sucked by the vacuum unit provided in contact with the lower surface of the belt transport unit.

The light source unit 10, the zoom lens 5, the dark shutter 4 and the like are controlled with respect to the negative set on the negative carrier 8 to expose the photographic paper.

When the exposure is completed, the photographic printing paper is again sent to the downstream side by the conveyor belt. Second roller 23 and discharge roller 24
The photographic paper is transferred from the belt to the photographic paper feeding unit.The feeding unit is composed of a plurality of feed roller pairs arranged at a pitch shorter than the minimum length of the cut photographic paper in the direction of advance, and the photographic paper is fed to the developing unit. Transport.

The back printer section 26 is provided in the middle of the sending section.
In this case, data such as exposure conditions can be printed on the back side of the printing paper.

Processing racks 34 to 38, turn guides 29 to 33, and a drying inlet guide 39 are sequentially arranged in the development processing section 50B, and predetermined development is performed. The developed printing paper is dried while passing through the drying rack unit and discharged to the outside of the developing machine.

The printer unit main body 50A and the development processing unit 50B are separable, and are docked and fixed as shown in FIG. 1 when the system is constructed. Further, the original winding magazine 1 is detachable from the printer body, and when the photographic paper is used up or when photographic paper of another width is used, the printer main body 50
It can be removed and replaced from A.

For positioning on the magazine 1 and the main body 50A, the magazine 1 is provided with a docking pin 61, and when set on the main body 50A, the docking pin 61 is fitted into a fitting hole inside the main body 50A to improve the setting position accuracy. I guarantee.

A scanner camera 15 is provided near the negative carrier 8, and each negative is imaged by the camera 15, and the data can be input to the CRT image input section.

Next, a minilab printer in which an exposure unit 50A for the film irradiation image for irradiating such a film image and printing it on a printing paper such as color paper as a light-sensitive material and its developing processing section 50B are connected, An embodiment of the photographic printing machine of the present invention in which the CRT image exposure unit 100 is attached to the developing system will be described.

A CRT image exposure unit is shown in the side sectional view of FIG.
The 1st Example which attached 100 is shown.

In this embodiment, the CRT image exposure unit 100
Is docked and fixed to the left side (printing paper magazine side) of the minilab printer unit main body 50A. The docking system is positioned by a docking pin 61 in the same manner as the magazine 1 and the printer main body 50A of the minilab, and the height is adjusted by the adjuster 163 in accordance with the printer main body cradle 165A.

On the left side surface of the CRT exposure unit, the magazine 1 used in the printer can be detachably set with the CRT image exposure unit 100.

The photographic printing paper P is pulled out from the magazine 1 by the feed roller 116, and the leading end of the photographic paper P is fed to the sub drive roller 16 of the printer unit main body 50A in a long size. When the tip reaches the roller 16, the feed roller of the CRT image exposure unit
The nip 116 is released and the photographic paper is fed by the roller 16 2
Two feed rollers (CRT unit and printer unit)
In order to prevent an error in feeding due to the roller 16, it is possible to prevent unnecessary back tension from being generated during the feeding by the roller 16.

The output image displayed on the CRT 110 is a lens (first lens L ₁ or second lens L ₂ ) and a total reflection mirror.
It is projected on the printing surface of the paper mask 113 through 112.

The paper mask 113 is formed in a plate shape having a hollow portion for cutting a projected image other than the printing screen which is required according to the conditions of the output print screen, and is arranged so that it can be replaced according to the conditions. However, the position of the opening surface,
The size may be variable so that mask replacement is not performed.

When the output image is exposed for a predetermined time, the dark shutter 104 shuts off the printing optical path to complete the exposure, and the sub drive roller 16 feeds the printing paper by the distance required for the next printing and the printer body side. The feed amount is stored in.

The center of the exposed portion (optical axis position) by the CRT and the center of the exposed portion (optical axis position) for exposure from a normal negative are preferably the most frequently used size (longitudinal direction, that is, the paper P in FIG. 2). It is preferable to take into account the screen boundary margin part of the paper conveyed in the normal cut state on the basis of the length in the exposure part), and make it an integer multiple of the sum of the paper length and the margin part, Easy to control and speed up.

However, it is preferable that the timings of the film image exposure and the CRT image exposure are shifted, for example, slightly in time so as not to be affected by the voltage drop due to the use of electric power.

Exposure and paper feed for several prints are sequentially performed, and the boundary portion of the already exposed screen is the cutter 17 of the printer body 50A.
When the position is reached, the feeding operation is stopped at 1 o'clock and the cutter 17 cuts the photographic paper. The cut photographic paper is conveyed in the same order as in the case of the printer alone, and if necessary, the printing operation is performed again in the exposure unit of the printer body. (For example, characters are printed on a CRT and a negative image is printed and synthesized on the printer side).

In the case of printing only the exposure section of the printer without printing the CRT screen, the printing paper is passed through the CRT unit section in an unexposed state, and printing is performed on the printer by the same control as the printing control of the printer alone. Is possible.

When the photographic paper P remains in the magazine 1, it may be replaced with a magazine 1 having a different photographic paper width if necessary.

In the above case, by inputting the information in advance from the operation unit, the rear end position of the final printing screen of the printing paper P is calculated, and the second cutter in the CRT image exposure unit 100 is calculated. 117 works. As a result, the area of the printing paper which is located outside the magazine and causes fog when the magazine 1 is replaced can be greatly reduced as compared with the case where the cutter in the printer is operated.

Instead of providing a second cutter in the CRT image exposure unit 100, a mechanism for rewinding the photographic paper in the magazine is provided, and most of the photographic paper outside the magazine is rewound in the magazine when the magazine is replaced. It is also possible to minimize the loss due to the fogging of the paper P.

In this CRT image exposure unit 100, two lenses L ₁ and L ₂ as a printing lens are switchably arranged, and the details thereof are shown in the side sectional view of FIG. 5 and
This is shown in the horizontal sectional view of FIG.

The two lenses of the first lens L ₁ and the second lens L ₂ are mounted on the lens board 171 which is engaged with the screw shaft 183 directly connected to the motor 184 via the bearing 181 via the screw shaft casing 171A. The first lens L ₁ is attached in FIG.
Is located on the optical axis for printing, and that position is in a state where the lens position detection sensor 173 detects the detection hole 175A on the lens board.

When the second lens L ₂ is used, the lens switching motor 184 is driven, and the second lens L ₂ position detecting hole 176A on the lens boat 171 is provided with the lens position detecting sensor 173.
The lens board 171 moves until it is detected by.

The lens board 171 is a lens board holder 170.
The guide rollers 172A, 172B mounted on the ball and the ball casings 177A, 177B are pressure-contacted by the crimping balls 179A, 179B urged by the springs 178A, 178B to stably position the lens regardless of the lens switching operation. Is done.

Two modes are prepared in which the CRT image can be reduced or enlarged within the range of the maximum output screen of the CRT, and at this time, a printing screen (print) of the same size can be obtained.

[0065] If when the magnification m ₁ <magnification m ₂ of the second lens L ₂ of the first lens L _1, m ₁ X if the CRT image dimensions of using each lens and X _1, X _{2 1} = m ₂ X ₂
X ₁ , X ₂ so that the image size on the photographic paper becomes
If you set, you can get the same size print. In this case, X ₁ > X ₂ .

That is, in the normal mode, the image output of X ₂ is printed by the second lens L ₂ , and when the fine mode is selected, the image output of X ₁ is printed by the first lens L ₁ to obtain a high quality image. It is possible to select according to the purpose so that the image can be printed.

The first and second lenses L _{1 of} the drawing shown in FIG.
A diffusing plate 189 is provided between L ₂ and the dark shutter 104 so that it can be inserted into the printing optical path, and is inserted into the optical path as needed.

This diffuser plate 189 is used as needed when a so-called sub-exposure effect is given by the CRT 110. As is generally known, the gradation characteristics of the photographic printing paper P are changed by applying a minute exposure before the exposure (main exposure) for image formation is applied to the photographic printing paper P so as not to cause fog. You can let me do it. The diffusing plate may be a ground glass or a liquid crystal whose transmittance can be varied by voltage.

FIG. 8 shows an experimental example of gradation change due to sub-exposure. The broken-line graph is a graph of the reflection density of a standard negative ring-around print (printed by changing the color and density during printing stepwise) using photographic paper that was previously sub-exposed before the main exposure. However, in particular, the slope of the print reflection density with respect to the printing light amount (energy) of the leg portion of the characteristic curve becomes gentle, so that the printing paper can be provided with a so-called soft characteristic. As a result, the range of exposure amount for tone reproduction of highlight scenes (for example, human faces during flash photography) can be expanded, and the optimum exposure condition setting range for printing can be expanded, resulting in print loss. Can be reduced.

When changing the gradation of the entire printing screen, a CRT is used.
Since it is preferable that the brightness of the screen is uniformly stabilized over the entire screen, the diffusing plate 189 can be inserted into the optical path if necessary.

It is also possible to change the gradation of only a part of the screen instead of changing the gradation of the entire screen as described above, but in this case, the diffusion plate is arranged outside the optical path. In this state, the luminance change at a specific position on the CRT screen will be dealt with.

The so-called "Oiyaki" used in news photographs (black and white) and the like is an example of this partial gradation change.

The CRT image does not necessarily have to be a color image. Adjust the color development ratio of each color (B, G, R) in advance so that a black and white print will result from the color development characteristics of the color photographic paper used for displaying the color film image on the CRT, or use black and white photographic paper for exposure. It is also possible to create a black-and-white print using a color photographic paper or a black-and-white photographic paper.

Another type of CRT image exposure unit 2 different from the CRT image exposure unit 100 shown in FIG. 2 is shown in FIG.
An example in which 00 is attached is shown. In this embodiment, by arranging the exposure surface of the CRT exposure unit in the vertical direction, firstly, the size of the CRT image exposure unit is reduced mainly for the purpose of compressing the entire width of the CRT image exposure unit. Secondly, up to the printer main body 50A. By shortening the distance from the magazine 1, it is possible to reduce the paper loss associated with magazine replacement during normal printing work. Since the second cutter 217 in the CRT image exposure unit 200 is not operated at the time of exchanging the magazine, it is possible to operate without changing the paper transport control sequence of the printer unit main body 50A alone. And CRT
During normal printing without image exposure, the paper feed path switching guide 291 waits in a state of moving downward from the illustrated position. The paper ejected from magazine 1 is the first feed roller 216A.
As a result, the nip of the first feed roller 216A is released after the paper is fed until it reaches the sub drive roller 16 in the printer unit main body 50A. Subsequent conveyance is the same as in the case of the embodiment shown in FIG.

When the magazine 1 is replaced, since the nip of the first feed roller 216A is released, the magazine 1 is released from the CRT image exposure unit 20 by releasing the lock lever between the magazine 1 and the CRT image exposure unit 200 (not shown).
It can be removed from 0. Next, when printing the CRT screen, the paper feed path switching guide 291 is moved to the position shown in the figure with the magazine 1 once removed in order to change the paper transport path.

The paper P conveyed by the first feed roller 216A is bent 90 ° by the path switching guide and is fed upward in the drawing. The paper is changed in the direction of 180 ° by the second feed roller 216B synchronized with the first feed roller 216A, forms a U-shaped path and is fed downward, and then is fed in the original horizontal direction by the paper feed path switching guide 291. When it reaches the sub drive roller 16 in the printer, the first and second feed rollers 21
The nip of 6A and 216B is released, and the subsequent feeding is performed by the sub drive roller 16.

Similar to the case of CRT exposure in the embodiment shown in FIG. 2, the boundary portion of the already exposed screen is the printer body portion.
When the paper reaches the position of the cutter 17 in 50A, the paper is cut, the cut paper is cut, and the subsequent conveyance is performed in the cut paper state.

When performing the last CRT exposure, the information corresponding to the rear end of the final exposure screen reaches the second cutter 217 in the CRT image exposure unit 200 by inputting the information to the CRT image exposure unit 200 in advance. At that time, the second cutter 217 is activated and the roll paper is separated.

When the CRT exposure is reunited again, the first feed roller 216A is nipped again and the paper P is fed as described above.
Will be sent.

In FIG. 3, the exposure table 213A is in a vertical position as shown in the drawing, and the CRT 210 located on the exposure table in the depth direction of the drawing.
Image is formed through the first and second lenses L ₁ and L ₂ and a dark shutter (not shown) total reflection mirror 212 (90 ° reflection).

The side sectional view of FIG. 4 shows an embodiment in which a CRT image exposure unit 300 is constructed between the printer unit main body 50A and the developing machine.

In this case, when the CRT image is printed, the cut photographic paper, which has been cut into a desired length by the cutter in the printer unit main body 50A in advance according to the information, passes through the printing unit of the film image printer unit without being exposed. Then, it is supplied into the CRT image exposure unit 300.

The sub-exposure described with reference to FIG. 2 cannot be applied in this case because it is necessary to give it before the exposure (main exposure) in the printer.

In the CRT image exposure unit 300, a paper mask 31 and a plurality of feed rollers formed at a pitch shorter than the final cut length for conveying cut paper.
3 A belt 319, a belt driving roller 318, and a vacuum box 325, which are located at the rear side, for sucking and conveying the color paper P are provided.

Incidentally, the belt driving roller 318 and the driven roller 323.
At least one of them is a crown roller, and it is desirable to give an automatic centering function to the meandering of the belt.

Before and after the belt transport section, the first feed roller 31 for feeding the paper P to the belt transport section (suction transport).
6A and a second feed roller 316B for receiving the paper P after the belt conveyance is arranged.

The CRT 310 is arranged in the depth direction of the drawing and projects the image on the paper mask 313 via the lenses L ₁ and L _{2, the} dark shutter (not shown) and the total reflection mirror 312.

A light emitting / receiving sensor 391 for confirming the paper position is provided in the vicinity of the upstream side of the paper mask 313, and the CRT is provided.
The color paper P can be accurately stopped at the position of the paper mask 313 by detecting the leading end of the paper P conveyed into the image exposure unit 300.

In this way, when the CRT image exposure unit 300 is docked on the downstream side of the printer main body 50A, the printer is read from the magazine 1 regardless of whether the CRT image is printed or the general film image is printed (normal print). The paper conveyance path to the outlet of the main body 50A is the same and the functions required for the original minilab system are sufficient. Further, since the color paper P is cut by the cutter in the printer unit main body 50A in advance, a new cutter function is not required in the CRT image exposure unit 300.

Next, the composition of the CRT image and the printer exposure image will be described.

The image resolution on the CRT screen is inevitably lower than that of the negative optical projection image, but on the other hand, there is an advantage that various image processing can be performed on the CRT screen.

In order to connect these two characteristics well, C
A print can be created by combining the RT image and the negative projection image.

For example, when synthesizing a CRT image such as characters and illustrations with a negative film image, the paper mask opening of the CRT printing part should be aligned with the projected part of the characters and illustrations, and the CRT screen should be printed. The formed paper may be stopped again at the printing unit of the printer unit main body 50A, and the image may be printed through a paper mask or the like having an opening at the required printing portion of the negative film image. Of course,
In the embodiment as shown in FIG. 4, the negative film image is printed first, and the CRT processed image of the character illustration is printed later. The composite image is, for example,
It becomes like the plan view of FIG.

In addition, the composition shown in FIG. 10 is performed by using a character original plate (such as a copy of characters on a lith film) to perform character printing for illustration on the screen in optical printing. This requires repeated baking, which is troublesome for printing, and causes deterioration of the image. Further, due to the above-mentioned work, in order to change the printing character, various works such as preparing and exchanging necessary lithographic originals are required each time.

Further, the index print is created by CR.
If it is synthesized on T, it can be done very easily.

FIG. 11 shows an example of an index print in which a negative film image of 24 EX is printed on one sheet of photographic paper. It is also possible to change the size and layout of each screen. However, doing this with optical printing requires a complex mechanism such as a very complex paper or negative two-dimensional moving mechanism.

Further, as shown in FIG.
It is also easy to create a sticker print printed on a sheet of photographic paper by the compositing function of the CRT. Optical printing requires a multi-lens such as a cluster lens or a complicated mechanism such as a negative or paper two-dimensional moving mechanism.

For the index print, it is possible to perform one-order optical printing by the CRT image exposure unit and the minilab main body, and then create and service the index print of the same order.

Further, as shown in FIG. 13, the CRT image exposure unit separately inputs the composition of the photographing date, place, description, etc., or reads the photographing date optically or magnetically recorded on the negative. It is easily possible to synthesize on top.

The above is the exposure printing of the film image and the CR.
Exposure printing of T image at different positions on photographic paper (color paper)
The method of printing and synthesizing on P. is particularly effective in improving the production speed of the printing for printing, but in order to achieve the purpose, the film image and the CRT image are printed at the same position almost at the same time. Provided is a photo printing device.

An embodiment having the structure shown in the side sectional view of FIG. 14 will be described.

Film image exposure unit (minilab main body) CRT 410 of CRT image exposure unit 400 is provided at a position perpendicular to the optical axis of the optical system of 50A, half mirror 412 is provided at the intersection of both optical axes, and printing paper for printing surface is provided. The image exposure of both units is performed on P at almost the same time.

The amount of reflected light and transmitted light of the half mirror is 50.
%, It is necessary to use a photographic paper having a high sensitivity corresponding to it.

As a result, the production speed of the exposure printing of the composite image can be maintained at a considerably high speed as in the case of the above-mentioned different position exposure.

Also, since the CRT image exposure can be preceded, albeit almost simultaneously, it is possible to improve the gradation of the film image by sub-exposure, and the illustration characters and imprinting are different from those described above. It is possible to freely combine the same as the position one. Of course, the exposure can be performed in two steps instead of simultaneously.

A specific method of creating the index print is as follows.

One order's worth is stored in the memory while being exposed, and after one order's completion, one order's worth is index printed by the CRT.

Images are decimated to 1/2 to 1/4 and stored, and are numbered from the start frame and stored together. All the image data may be stored and thinned out before being output.

When the exposure for one roll is completed, after the last frame, as an index print, for example, all 24 frames are reduced and printed in one service plate size.

By reading the film maker and the type signal recorded on the roll film and determining the size of the corresponding index print sheet, the index print that matches the size of the negative holder or is easy to set. Therefore, it is preferable.

In addition to this, when half size is added to panorama or high-definition size in one roll (mixed processing), mode selection is possible, and panorama is an area for two standard sizes. The panoramic size fits within the standard size in the horizontal direction. The half size is half the standard size (prints on the negative size as it is), and the half size is 90. Rotate and display the image in the same size as the standard size. Corresponding to the above mode, display and print the same as the index print on the CRT.

It is also possible to change the color of the edge portion for each splice so that it can be distinguished from other film rolls. CR
It can be easily distinguished by changing the background color of T.

In order to correct the distortion of the image on the print due to the curvature around the CRT, the CRT display is performed by applying the correction coefficient prepared in advance.

As another method, the print may be printed by displaying the whole frame in a small size on the center of the CRT and moving the optical system to make it larger than usual.

On the CRT, it is preferable to display the frame number assigned to each roll at the bottom of the screen or the like.

Further, when the shooting date information is stored in the negative, it is preferable to display the shooting date beside the frame number.

At this time, the information of the earliest date and the latest date of the photographing date information may be read and recorded in a part of the index print. The effect is that you can instantly see when the roll film was shot.

On the basis of the average density of each frame and the information obtained by the LATD photometry, the dark landscape of the frame can be displayed brightly on the CRT. In the case of index print, it is reduced, so it is possible to avoid making it difficult to read what was shot in a dark landscape.

A bright image may be difficult to read if it is reduced, and at least a bright image may be displayed on a CRT and printed by performing edge enhancement processing or widening the density distribution.

Even in the case of a dark image frame as a whole, expanding the density distribution is a preferable process.

Although the case where the index print is displayed on the CRT as one screen with one roll has been described above, the index print may be divided into two pieces or a plurality of pieces to be displayed and combined into one piece on the print. . This method requires some manipulation of the optics, as the CRT has less fine pixels, but the quality of the result is good.

By inserting the date and time of printing and the name of the DPT store in a part of the index print,
In addition, it can be useful for the next re-burning.

Since the index print is often held on the outside of the case or the like without being attached to an ordinary album, color correction may be performed in advance so as to have light resistance.

Similarly, although not shown, a laminating step can be automatically applied after development and fixing so as not to be damaged. In this case, an ultraviolet ray transmission inhibitor may be mixed in the laminate resin.

Next, the effect of the sub-exposure described above will be specifically described.

In order to control the finish gradation of printing, the sub-exposure has been performed on the entire surface with a lamp or the like until now, but unevenness of the light amount may occur, and it is necessary to maintain the uniformity of the irradiation light.

C used to print the electronic image this time
Sub-operation could be performed using RT. The entire surface is exposed with a single color, but white is generally used. However, light pink or light yellow can be intentionally sub-exposed.

Further, even if an attempt is made to irradiate white light, there is a danger that the light will be emitted from the phosphor and not completely white. Therefore, it is also possible to carry out a second sub-exposure with a color that compensates.

Further, in order to prevent the unevenness of the scanning line of the CRT from being reflected on the image, the scanning beam of the CRT may be slightly enlarged at the time of the sub-exposure so as to be blurred so that there is no local unevenness. it can. Although the CRT seems to emit light entirely to the human eye, since it is actually scanning at a high speed, the irradiation time of the sub-exposure is faster in the non-interlaced CRT than in the interlaced CRT. In either case, it depends on the frequency of the power used, but in the case of 50 Hz, a time that is an integral multiple of 20 msec is good. That is, it is necessary to make the light emitted from each pixel uniform.

When there is a failure piece in 24 rolls of negative film, it is displayed as the first measure, and the index piece is displayed as it is, and a mark such as "(defective)" is added to the frame indicating that it is not good. Either, or as a second measure, switch the display to the one that does not display the failed piece and replace it with a mark or other colorful display and display it to index burn it. be able to.

According to the present invention, film image exposure and CR
Both of the T image exposure and the combined exposure printing can be processed quickly and efficiently at a high production rate.

Further, as a result, the CRT image exposure can be used as a sub-exposure means for the film image exposure, the gradation can be stabilized, and the range of exposure amount for tone reproduction can be widened, and the apparatus can be used. Without upsizing,
It has become possible to greatly reduce print loss.

Further, since it is possible to easily perform the burning composition of the illustration characters, it is possible to easily realize the multifunctional printer function for performing the film image exposure.

Further, for CRT image exposure, it is possible to switch a plurality of lenses having different magnifications to give different image resolutions.
