Abstract

PURPOSE:To accurately perform the positioning for image composition by providing a means for forming a photosensitive material in a free loop on the entrance side of common guides for two exposure stages which are provided along a conveyance path for the photosensitive material. CONSTITUTION:The looper means 11 which form the photosensitive material 1 in the free loop is provided on the entrance side of the common guides 12 and 13 which guide the photosensitive material 1 to the two exposure stages 5 and 6 arranged along the conveyance path for the photosensitive material 1. Thus, the free loop is formed on the entrance side of the common guides 12 and 13 for the two stages, so a drawing-out roller couple 15 for positioning the photosensitive material 1 at the 1st and 2nd stages 5 and 6 has no back tension and a slide due to back tension at the time of feeding the photosensitive material 1 is eliminated. Consequently, multiexposure image planes of a photographic image and a CRT image are positioned accurately and mutually.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image composition printer, and particularly to an image composition printer that improves the accuracy of positioning in image composition.

[Conventional technology]

For example, as an image compositing printer that prints a photographic image and a CRT image overlappingly to combine the images, for example, a movable mirror that can be inserted into and removed from the optical axis of the photographic image exposure system is installed, and the movable mirror allows the photographic image to be There has been proposed an apparatus that forms a CRT image from a CRT image exposure system at the exposure position and performs overlapping printing (for example, Japanese Patent Laid-Open No. 58-122529).

[Problems to be Solved by the Invention] However, in the above-mentioned image composition printer, since a photographic image and a CRT image are selectively formed on a photosensitive material by a movable mirror, for example, a CRT image is formed by a movable mirror. When forming an image on a photosensitive material, there is a problem that the optical axis adjustment becomes complicated. Also, because of the mirror mechanism,
If the imaging lens is moved when changing the magnification, the lens hits this movable mirror, which causes a problem in that the magnification is limited.

In contrast, a dedicated exposure stage is provided for each of the photographic image and CRT image for overlapping exposure, and the first stage performs the first exposure, and then the exposed frame is transported a certain amount to the second stage. It is also conceivable that the second exposure is performed by positioning the target on the stage shown in FIG. However, in this case, there is a problem in that if the feeding accuracy of the photosensitive material is poor, positioning for image composition cannot be performed accurately. That is, in order to position the photosensitive material on the exposure stage, a pair of conveying rollers for drawing out the photosensitive material is provided. Since the back tension of this pair of transport rollers changes depending on the use of the photosensitive material, slippage occurs in the feeding of the photosensitive material, and since the amount of slippage changes, accurate constant speed cannot be achieved. Therefore, it is not possible to precisely align the mutually exposed screens.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an image composition printer that has a simple configuration and can perform positioning for image composition with high precision.

[Means to solve the problem]

In order to achieve the above object, the present invention has two exposure stages arranged side by side along the conveyance path of the photosensitive material, a common guide for guiding the photosensitive material on the two exposure stages, and an entrance side of the common guide. A looper means is provided to make the photosensitive material into a free loop.

The two exposure stages are a photographic image exposure stage and C
'It is preferably a stage for RT image exposure. Further, the interval between the two exposure stages may be set so that printing can be performed simultaneously on the two exposure stages. Furthermore, it is preferable to control the timing of feeding the photosensitive material to each stage so that printing is performed separately in the two exposure stages.

In addition, there are two exposure stages arranged in parallel along the conveyance path of the photosensitive material, a common guide for guiding the photosensitive material to these two exposure stages, and a common guide placed on the entrance side of the common guide for guiding the photosensitive material. a louver means for making a free loop; a pair of conveying rollers for setting the photosensitive material on the two exposure stages; and a pair of conveying rollers for feeding the photosensitive material in order to print simultaneously or separately on the two exposure stages. An image synthesis printer may be constructed from a feed control means that selectively switches the timing.

[Effect]

When two images, for example a photographic image and a CRT image, are to be printed overlappingly on a photosensitive material, first, for example, the photographic image is printed in the first stage, and then the photosensitive material is conveyed one frame.
In the second stage the CRT image is printed. At this time, 2
Since a free loop is formed on the entrance side of the common guide for the two stages, there is no back tension of the pull-out roller pair for positioning the photosensitive material on the first and second stages, and the back tension when feeding the photosensitive material is eliminated. It can eliminate slippage. As a result, the photosensitive material can be accurately fed by a predetermined amount, and the mutual positioning of the photographic image and the CRT image can be performed with high precision during overlapping exposure.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1 showing an image synthesis printer processor in which the present invention is implemented, a photosensitive material such as color paper 1 is
It is stored in a roll in the magazine 2. This color paper 1 is pulled out from the magazine 2 by a pair of conveying rollers 3, and set by a pair of conveying rollers 15 on a first exposure stage 5 where a photographic image is printed and a second exposure stage 6 where a CRT image is printed. . These first and second exposure stages 5.6 are arranged in parallel along the conveyance path of the color paper 1, and a common pressure plate 7, which also serves as a guide member for the color paper 1, is connected to the first exposure stage 5. A mask 8 is placed on the exposure stage 6, and a mask 9 is placed on the second exposure stage 6. Note that although the masks 8 and 9 are provided separately, they may be integrated. The interval between the first and second exposure stages 5.6 is set so that the color paper 1 is set on each exposure stage by the pair of transport rollers 15 transporting the color paper 1 by one frame. It is said that

A free loop forming stage 11 for bending the color paper 1 upward to form a free loop 10 is provided between the inlet side of the pressure plate 7 and the pair of conveying rollers 3. This stage 11 includes a horizontal guide plate 12 for guiding the leading edge of the color paper 1 to be positioned on the first exposure stage 6, and a horizontal guide plate 12 that is placed close to the inlet side of the pressure plate 7, which is used to guide the tip of the color paper 1 when forming a free loop. It is composed of a guide roller 13 for guiding. Further, a pair of conveying rollers 15 for setting are arranged close to the exit side of the color paper 1 of the pressure plate 7 for pulling out the photosensitive material 1 formed in the free loop 1O and setting it on each exposure stage 5.6. ing. This conveyor roller pair 1
5 and a pair of transport rollers 3 disposed on the entrance side of the free loop forming stage 11 are rotationally driven by pulse motors 16 and 17, and these pulse motors 16 and 17 control the driver 1 based on control signals from a controller 52, which will be described later.
Driven by 8.19.

After the leading edge of the color paper 1 is nipped by a pair of conveyance rollers 15 for setting, a pair of conveyance rollers 3 on the entrance side transfers the color paper 1 by a length corresponding to a length of one frame or more to form a free loop. This is done by conveying the paper 1.

Note that when the free loop 10 is transported by the set transport roller pair 15 and becomes less than a predetermined length,
The pair of entrance side conveyance rollers 3 is driven to form a free loop 10 of a constant length or more at all times. This free loop E0 is provided to prevent back tension from being applied to the pair of conveying rollers I5 when the color paper 1 is pulled out by the pair of conveying rollers 15 for setting.

A photographic image exposure system 20 and a CRT image exposure system 21 are arranged corresponding to the first and second exposure stages 5.6. The photographic image exposure system 20 prints a photographic image, for example, a negative image of a color negative film 22, onto the color paper 1 of the first exposure stage 5. The CRT image exposure system 21 prints character images such as texts and addresses, logo marks, computer graphic images (C0 images), etc. onto the color paper 1 via the CRT.

The white light emitted from the white light source 23 passes through the diffusion box 24 and the film carrier 25, reaches the negative film 22 set at the printing position, and illuminates it from below. The diffusion box 24 is composed of a rectangular tube whose inner surface is formed into a mirror surface, and diffusion boxes attached to both open ends of the rectangular tube. A cyan filter 26, a magenta filter 27, and a yellow filter 28 are arranged between the diffusion box 24 and the white light source 23 to adjust the quality of illumination light. The filter adjustment unit 29 controls the amount of each of the color filters 26 to 28 inserted into the optical path, and adjusts the quality of the illumination light according to the negative image on the negative film 22. The negative film 2
°2 is applied to the film carrier 25, and the mask 3
1 is pressed down from above.

A zoom lens 32 is arranged above the film carrier 25, which allows the negative image of the negative film 22 to be captured in the first lens while the shutter 33 is retracted from the optical path.
The image is formed on the color paper l of the exposure stage 5. This boom lens 32 enlarges or reduces a negative image to a desired size, and the focal length can be changed by manual operation. The opening and closing of the shutter 33 is controlled by a shutter driving section 34, and is configured to open only for a time corresponding to the sensitivity of the color paper 1.

Facing the color paper 1 of the second exposure stage 6, a black-and-white CRT 40 is arranged at the bottom, and when printing, it prints a black-and-white image in which a red image, a dusk image, and a blue image of the negative image are each displayed in brightness. The images are displayed sequentially for a predetermined period of time.

Above this black-and-white CR'r40, there is a zoom lens 41 for focusing the image of the CRT40 on the color paper 1 of the second exposure stage 6, and a zoom lens 41 for converting the black-and-white image of the CRT40 into a monochromatic image of red, green, and blue. Red filter 4 for
2. A green filter 43, a blue filter 44, a filter switching unit 45 for selectively inserting these filters 42 to 44 into the optical path, and a monochromatic image of each color on the color paper 1.
A shutter 46 is arranged to print the image for a predetermined period of time. The filter switching unit 45 selectively inserts the red filter 42 into the optical path when a black and white image in which a red image is displayed in brightness is displayed on the CRT, and exposes the red image onto the color paper 1. ing. Similarly, when a black-and-white image corresponding to a green image and a black-and-white image corresponding to a blue image are sequentially displayed on the CRT 40, a green filter 43 and a blue filter are sequentially inserted into the optical path in response to this, and the three-color surface Exposure is performed sequentially. The shutter 45
is controlled by a shutter drive section 47.

The color paper 1 that has been exposed repeatedly at the first and second exposure stages 5.6 is sent to the developing section 4, where it is developed, cut into frames by a cutter, and discharged onto a tray 49. Ru.

FIG. 2 shows a CRT display device 50 for displaying text, character images such as addresses, logo marks, 00 images, etc. on a black and white CRT 40. As the graphic image input device 51, for example, an image scanner is used, and a logo mark or the like is input into the controller 52.

Further, characters such as address and name can be entered manually from the keyboard 53. This keyboard 53 is also used to operate each part. Furthermore, the 00 image written on the floppy disk 54 or the magnetic tape 55 can be input to the controller 52 via the recording medium drive circuit 56.

Further, this controller 52 can electrically synthesize characters manually inputted from the keyboard 53 and logo marks etc. manually inputted from the graphic image input device 51 by adding these characters.

The image input to the controller 52 is subjected to logarithmic conversion and color correction, and then stored in the frame memory 58 in a separated state for each color. The color signals stored in the frame memory 58 are read out during printing and sent to the image magnification conversion circuit 59, where the size of the CRT image is expanded or reduced to the magnification specified by the keyboard 53. It is sent to lookup table 60. The lookup table 60 performs gradation correction according to the gradation of the color paper 1 and positive/negative inversion. Note that when using reversal color paper, positive/negative conversion is not performed.

The output signal of the lookup table 60 is converted into an analog signal by a D/A converter 61 and then sent to a selection circuit 62.
sent to. The selection circuit 62 takes out any one of the three color signals and CRs it.

The signal is sent to the T drive circuit 64. The CRT drive circuit 64
A black and white image such as characters is displayed on the display screen 40.

The controller 52 is composed of a microcomputer, and in addition to controlling the CRT image exposure system 21 as described above, it also controls the photographic image exposure system 20, the development processing section 48, and the motors 16 and 17 of the respective conveyance rollers 3 and 15. control etc.

The motor 17 of the transport roller pair 15 for setting the color paper 1 on the first and second exposure stages 5 and 6 is controlled by a feed control means 52a in the controller 52. This feed control means 52a controls the color paper 1
The feed timing is selectively switched between simultaneous print feed and individual print feed by a feed switching signal from the keyboard 53 or the like. Simultaneous print feeding is to feed color paper 1 by the pitch of one print frame.
Thereby, new color papers 1 can be set simultaneously on the respective exposure stages 5 and 6, and these set color papers 1 can be exposed simultaneously. Further, the individual print feed is a feed for individually setting the color paper 1 on each of the exposure stages 5 and 6, and after the color paper 1 is set individually, exposure is performed on this stage. By switching the feeding timing of the color paper l in this manner, printing can be performed simultaneously or individually at each stage 5.6.

Next, the operation of this embodiment will be explained.

A color negative film 22 containing images of people, scenery, etc. is transferred to a film carrier 25 of a photographic image exposure system 20. In addition, the logo mark inputted from the graphic image human input device 51, the characters inputted from the keyboard 53, the 00 image inputted via the storage medium drive circuit 54, etc. are synthesized as necessary, and then each color is combined. It is separated into two parts and stored in the frame memory 58.

First, a photographic image on a negative film 22 is printed onto the color paper 1 set on the first exposure stage 5. The filter adjustment section 29 adjusts the insertion amount of the color filters 26 to 27 into the optical path according to the color density of the photographic image.

After this adjustment, the white light source 23 emits light. Immediately after this,
Since the shutter 33 is opened for a predetermined time, the photographic image of the negative film 22 is printed onto the color paper 1 by the zoom lens 32. When the printing of the photographic image is completed, the color filters 26 to 28 are returned to their standard positions, and the white light [23] is turned off.

Next, the frame on which the photographic image has been printed on the first exposure stage is set on the second exposure stage 6 by the pair of setting conveyor rollers 15 conveying the color paper 1 for one frame. Along with this setting of the exposed frame by the first exposure stage 5 on the second exposure stage 6, a new unexposed color paper 1 is set on the first exposure stage 5.

A photographic image of the negative film 22 is printed on the new color paper 1 set on the first exposure stage 5 in the same manner.

The first and second exposure stages 5 of this color paper 1,
6, color paper 1 is set using conveyor roller pair 15.
This is done by feeding a predetermined amount. At this time, since color paper 1 having a length of one frame or more is stored in advance as a free loop on the free loop forming stage 11, pack tension does not act on the pair of conveying rollers 15, and the pair of conveying rollers When the color paper 1 is fed by the color paper 15, slippage due to back tension does not occur. Therefore, the frame on which the photographic image has been printed on the first exposure stage 5 can be accurately positioned on the second exposure stage 6.

The CRT image exposure system 21 is operated to start printing a CRT image on the color paper 1 which has been exposed to a photographic image and is set on the second exposure stage 6 .

Each color signal of a positive image is read out from the frame memory 58, and after being converted to a predetermined magnification via an image magnification conversion circuit 59, the positive/negative image is inverted in a look-up table 60, and then the D/A converter 61, it is converted into an analog signal. The selection circuit 62 first takes out the red signal and sends it to the CRT drive circuit 64, causing the CRT 40 to display an image corresponding to the brightness of the red image. When a red image is displayed on the CRT 40, a red filter 42 is inserted into the optical path of the lens 41, and the image displayed on the CRT 40 is converted into a red image. In this state, shutter 4 is pressed for the exposure time determined according to the red sensitivity of color paper 1.
6 is opened, and a red image is printed onto the color paper 1 during this time. Similarly, a green image and a blue image are printed on the color paper 1, and the sequential exposure of the three color planes is completed.

Although the simultaneous print feed operation in which printing is performed simultaneously on each stage 5 and 6 has been described so far, it is also possible to select individual print feed instead. In this case, is there a delivery system? The ff11 means 52a is switched to the individual print feeding side, and each exposure stage 5, 6 is automatically
Color paper 1 is individually set at each stage, and printing is automatically performed at each exposure stage.

The above procedure is repeated to sequentially expose a plurality of frames of color composite images onto the color paper 1.

When a predetermined number of frames have been printed, the rear end of the color paper 1 is automatically cut, and this color paper 1 is developed in the development processing section and cut into 9 pieces.
It is discharged onto a tray 49.

In this embodiment, since bank tension is not applied to the set conveyance roller pair 15 when conveying the color paper 1, when overlapping exposure is performed, the photographic image 70 and the CRT image 71 are separated as shown in FIG. and can be burned in correctly at the predetermined position. In the example shown in FIG. 3, a photographic image 70 is placed at the top and a CRT image 71 is placed at the bottom.
This arrangement can be changed as appropriate; for example, photographic images and CRT images can be arranged in the width direction.

In the above embodiment, in order to form the free loop 10, after the leading end of the color paper 1 is nipped by the pair of conveyor rollers 15 for the cellar 1, the color paper 1 is moved to the entrance side by a length of one frame or more. The free loop 10 is conveyed by the conveying roller pair 3 for setting, and the free loop 10 is conveyed by the conveying roller pair 1 for setting.
5, and when the length becomes less than a predetermined length, the inlet side conveyance roller pair 3 is driven to form a free loop 10 that is always longer than a certain length, but instead of this, , other methods, for example, a pair of conveying rollers 3 on the entrance side
A free loop may be formed by making the conveying speed of the set conveying roller pair 15 faster than that of the set conveying roller pair 15.

Furthermore, in the above embodiment, the CRT image is printed in 3
Although the color plane sequential exposure is used, the present invention is not limited thereto, and may be performed by line exposure using a flat CRT, or exposure using a laser beam deflected by a galvanometer, a polygon, or the like.

Further, in the above embodiment, the photographic image exposure system 20 is arranged on the first exposure stage 5, and the CR
Although the T-image exposure system 21 is arranged to combine a photographic image and a CRT image, the present invention is not limited to this, and can print only a photographic image or a CRT image, or combine photographic images or It is also possible to combine CRT images.

4゜In addition, in the above embodiment, in addition to the printer that combines and prints images, the printer processor is equipped with a development section that develops the exposed photosensitive material, but the present invention is not limited to this. It is also possible to create an image composition printer without the development processing section.

〔Effect of the invention〕

As explained above, according to the present invention, a common guide for guiding the photosensitive material is provided on two stages arranged in series, and a looper means for free looping the photosensitive material is provided on the artificial side of this common guide. The back tension of the pair of conveyance rollers for setting for positioning the photosensitive material on the first and second stages is eliminated, and slippage caused by the back tension when feeding the photosensitive material can be eliminated. This allows the photosensitive material to be accurately fed by a predetermined amount.
For example, when combining a photographic image and a CRT image, these images can be aligned with high precision.
