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

〔Example〕

1 and 2 show an embodiment of the present invention. A magazine 3 is detachably set in the upper left portion of the main body 2 of the photoprinting apparatus, and a photosensitive material such as photographic paper 4 is wound in a roll and accommodated therein. This photographic printing paper 4 is intermittently pulled out by a pull-out roller 5 to be exposed in an exposure chamber 6
It enters the inside and is sent to the exposure position located between the easel mask 7 and the pressure plate 8. On the right side of the easel mask 7, a cutter for cutting the exposed photographic printing paper 4 in a short length is arranged.

A white light source 11 is provided below the exposure chamber 6. The white light emitted from the white light source 11 passes through the diffusion box 12 and the film deck 13, reaches the photographic film, for example, the color negative film 14 set at the printing position, and illuminates it from the bottom. The diffusion box 12 is formed by a square tube formed on the inner surface of the mirror surface and a diffusion plate attached to the open ends of both ends thereof. Between the diffusion box 12 and the white light source 11, a cyan filter 15 for adjusting the red component of the illumination light, a magenta filter 16 for adjusting the green component, and a yellow filter 17 for adjusting the blue component are provided. Are arranged. The filter adjustment unit 18
The amount of each of the color filters 15 to 17 inserted into the optical path is controlled, and the light quality of the illumination light is adjusted according to the image of the color negative film 14 (hereinafter referred to as a negative image). The color negative film 14 is pressed from above by a mask 19 operated by a solenoid (not shown) at the time of photo printing. In the case of printing a reversal film or a positive image of a printed photograph, reverse color photographic paper and a special developer are used, and in this case, printing from a negative film is not possible.

An opening 21 is formed in the lower portion of the exposure chamber 6, and a printing lens 20 is detachably attached to the opening 21. It should be noted that the image capturing lens 20 may be slid to retract from the image capturing optical path when the image is captured by the TV camera.

A double-sided mirror 22 is disposed on the printing lens 20, and when printing a negative image, the double-sided mirror 22 is printed by a mirror driving unit 71 such as a solenoid.
Are evacuated from.

The shutter control unit 25 controls the opening and closing of the shutter 24. When printing a negative image with a photographic image exposure system, the shutter 24 is opened once for a time corresponding to the sensitivity of the printing paper, and then a video image is displayed with the CRT exposure system. For baking, open and close once for each color, three times in total. This is because a black and white CRT is used in the CRT exposure system in order to enhance the resolution. Therefore, if you use a color CRT,
Video images can be printed on color photographic paper in one go. The present invention can also be used in the case of printing a black-and-white image on a black-and-white printing paper.

A CRT 27 that constitutes a CRT exposure system is arranged in the lateral direction of the double-sided mirror 22. The CRT 27 sequentially displays a monochrome image in which a red image, a green image, and a blue image, which are negative images, are represented by luminance during printing. In order to observe the video image to be printed, a monitor 40 is mounted on the main body of the photo printing apparatus 2, and a positive image is displayed on the monitor 40.

A TV camera 28 is arranged so as to face the CRT 27 via the double-sided mirror 22, and a negative image of the negative film 14 set on the film deck 13 is picked up and inputted to the CRT exposure system.

The CRT 27 displays a black-and-white image in which the image of the red, green and blue components of the negative image is represented by the luminance when the video image is printed. In order to convert this black-and-white image into a single color image of red, green and blue, A red filter 42, a green filter 43, and a blue filter 44 are arranged between the printing lens 41 and the mirror 21, and are selectively inserted into the optical path of the printing lens 41 by the filter switching unit 45.

A development processing chamber 48 is formed on the right side of the main body 2 of the photographic printing apparatus, in which a color developing tank 50 and a bleach-fixing tank 5 are formed.
1, a washing tank 52, a drying drum 53, a cutter 54 for cutting into one frame, and a large number of rollers 55 for transferring the photographic printing paper 4 are appropriately arranged between them. In the development processing chamber 48, the exposed photographic printing paper 4 is sequentially subjected to color development, bleach-fixing, water washing and drying steps to form a positive image on each frame, and finally is cut by the cutter 54 one by one to be tray 56. Is discharged to.

FIG. 3 shows the electrical configuration of the present invention. The TV camera 28 and the video image input device 60 built in the photo printing apparatus main body 2 are connected to the selector 61. The video image input device 60 is for inputting a video signal such as a figure stored in an image storage medium. The selector 61 selects one of the video signals input by the TV camera 28 and the video image input device 60, sends it to the A / D converter 62, and converts it into a digital signal. The video signal converted into the digital signal is separated into the color signals and stored in the memory 63 via the image processing device 29. Further, this memory 63 can store a plurality of video images so that a plurality of negative images can be printed side by side.

The image processing device 29 performs image synthesis, for example, arranging different images or the same image in a matrix, or embedding characters or figures in a video image, as well as image enlargement, reduction, shift, color and Correct the density. The image-processed video signal is converted into an analog signal by the D / A converter 72, and then sent to the monitor system and the print system, respectively. This monitor system is composed of a driver 73 and a monitor 40, and displays a video image to be printed on the monitor 40 in color. The printing system is
It is composed of a positive-negative inverting circuit 66, a selector 67 for taking out the inverted three-color signals (red signal, green signal, blue signal) at the time of selection, a driver 68, and a CRT 27.

The keyboard 65 includes a power key, a print start key, etc., and inputs necessary commands to the controller 64.
According to the program, the controller 64 controls the filter adjusting unit 18, the shutter driving unit 25, the filter switching unit 4
Photo printing unit 69 composed of 5 and the like, and processing tanks 50 to 5
2, a photo developing unit 70 including a drying drum 53, a cutter 54, etc., a mirror driving unit 71, selectors 61, 6
7 and the like are sequence-controlled.

Next, the operation of the above embodiment will be described. When printing a negative image, the color negative film 14 to be printed is set on the film deck 13. Normally, the color filters 15 to 17 are inserted in the standard position, and the illumination light emitted from the white light source 11 in the dimmed state is adjusted to the standard light quality. The filter adjustment unit 18
The insertion amount of the color filters 15 to 17 into the optical path 23 is automatically adjusted according to the measurement value measured by a scanner (not shown). If the print key of the keyboard 65 is operated after this adjustment, the white light source 11 emits full light and
Since the shutter 24 is opened for a predetermined time, the negative image of the color negative film 14 is printed on the printing paper 4 by the printing lens 20. When the printing of the negative image is completed, the color filters 15 to 17 are returned to the standard position, and the white light source 11 is in the dimmed state. At the same time, the unexposed photographic printing paper 4 is pulled out from the magazine 3, and the exposed portion is sent to the development processing chamber 48.

The above procedure is repeated to print a plurality of negative images on the printing paper 4, but this portion forms a loop and is temporarily stocked. When the number of frames designated in advance is exposed, the cutter 9 is activated to cut it into short pieces, and the exposed photographic printing paper 4 is transferred toward the color developing tank 50. This short photographic paper is subjected to photographic development processing by a roller 55 through a color developing tank 50, a bleach-fixing tank 51, a water washing tank 52, and a drying drum 53 in that order. The color printing paper on which a positive image has been formed by the developing process is cut by the cutter 54 frame by frame and then discharged to the tray 56.

Next, with reference to FIG. 4, description will be made on a case where a plurality of negative images are printed on one print photograph by using the CRT exposure system. First, the color negative film 14 is set on the film deck 13, and the printing lens 20 is removed from the opening 21. Next, when the CRT exposure system is switched by the keyboard 65, the TV camera 28 is turned on and the white light source 11 emits light to illuminate the color negative film 14 set on the film deck 13. In addition, the double-sided mirror 22 in the retracted position has the mirror driving unit 7
It is rotated by 1 and is inserted into the optical path 23 in a state of being inclined at 45 degrees. If the tilt angle of the double-sided mirror 22 is not 45 degrees, a distorted image is displayed on the CRT 27.
Since this image is projected on the photographic printing paper 4 by the same double-sided mirror 22 whose inclination angle is not 45 degrees, the image formed on the photographic printing paper 4 does not deviate. Also, when the double-sided mirror 22 is warped, a distorted image is displayed on the CRT 27, but since this image is projected on the photographic paper 4 by the same double-sided mirror 22, the image formed on the photographic paper 4 is There is no distortion. At the same time, the filter adjusting unit 18 adjusts the light quality of the illumination light.

The light passing through the color negative film 14 is reflected by the double-sided mirror 2
It is reflected by 2, enters the TV camera 28, and is converted into a video signal. This video signal is sent to the selector 61, A /
Sent to the image processing device 29 via the D converter 62,
It is stored in the memory 63. The color negative film 14 is moved to pick up the next frame and store it in the memory 63.

After the frames are sequentially imaged in this manner, the keyboard 65 is operated to fit and combine the frames. After confirming this combined state on the monitor 40, the print key of the keyboard 65 is operated to burn the combined video image. That is, since the synthesized video image is stored in the memory 63, the synthesized video image is read from the memory 63 and sent to the selector 67 via the positive-negative inverting circuit 66. The selector 67 first extracts, for example, a red image signal, sends it to the CRT 27 via the driver 68, and causes the CRT 27 to display an image corresponding to the brightness of the red image (more accurately, the negative image of the red image). When a red image is displayed in black and white on this CRT 27, the red filter 42
Is inserted in the optical path of the baking lens 41, and the black and white image displayed on the CRT 27 is converted into a red image. In this state, the shutter 24 is opened for the exposure time determined according to the red sensitivity of the printing paper 4, and the red image is printed on the printing paper 4 during this period.

After the exposure of the red image, the shutter 24 is closed, during which the red filter 42 is retracted, and instead the green filter 4 is replaced.
3 is inserted. At the same time, a green image is displayed in black and white on the CRT 27. Immediately after this, since the shutter 24 is opened again, the monochrome image displayed on the CRT 27 is converted into a green image by the green filter 43, and the photographic printing paper 4 is exposed. Similarly, the blue image displayed on the CRT 27 is exposed on the photographic printing paper 4. When a video image is printed on the photographic printing paper 4 by this three-color sequential exposure method, the photographic printing paper 4 is moved by one frame and the unexposed portion is set at the exposure position.

As described above, the exposed photographic printing paper 4 is transferred to the development processing chamber 4
After being sent to the inside of the tray 8 and subjected to photographic development processing, they are cut into frames one by one and then discharged to the tray 56.

As a result of the above-mentioned inset composition, a print photograph 79 is produced by printing four negative images 75 to 78 shown in the color negative film 14 as shown in FIG.

In the above-mentioned embodiment, four different negative images are printed on one print photograph, but it is also possible to print a plurality of the same negative images side by side. It is also possible to combine one negative image, characters input by a keyboard or the like, or a computer graphics image created by a digitizer, display the combined image on a CRT, and print it on photographic paper.

When a video image is printed in the same manner as in the conventional case, the video image is input from the video image input device 60, the image processing device 29 corrects the color and density, and then the CRT 27.
You can display it in.

〔The invention's effect〕

As described in detail above, according to the present invention, a double-sided mirror is arranged in the printing optical path, and the photograph film set on the VCR is imaged by the TV camera through one mirror surface, and the obtained video is obtained. The image is processed and sent to a CRT for display, and the video image displayed on the CRT is printed on the photosensitive material through the other mirror surface. You can use the deck and light source. Therefore, it is not necessary to provide a special film deck or a light source for picking up an image of the photographic film, so that the cost can be reduced as a whole.
