Abstract

PURPOSE:To form a three-dimensional image faithful to an original image by a simple operation by overlapping the image data obtained from the image to be copied of a photograph using an electrophotographic copier with the image data obtained by rotating the image to be copied by a specific angle and imagewise exposing a photosensitive material using the overlapped image data to develop the photosensitive material. CONSTITUTION:When an image to be copied (manuscript) is obtained from the photograph baked on printing paper, a first copy image 2 is formed, for example, on an OHP film from the manuscript using an electrophotographic copier. Next, the manuscript is rotated by 90 deg. and a second copy image 3 is formed in the same way. These copy images 2, 3 are superposed one upon another to be applied to a photosensitive resin 8 to expose the resin. Subsequently, the exposed resin is developed by flowing water and the entire surface of the developed resin is exposed to form a hard resin mold 9. Metal flame spraying is applied to the uneven surface of the mold 9 and the mold 9 is removed to form a female mold 13. A metal 14A is applied to the female mold 13 by flame spraying to obtain a three-dimensional image. Further, a product can be also obtained by applying a coating or plating to the mold 9.

An embodiment of the present invention will be described below.

<Embodiment 1> This embodiment and Embodiment 2 described later
Is an example in which a photograph (a positive image with respect to the original image) printed on photographic paper is used as an image to be copied (hereinafter referred to as an original), and copying is performed by regular development. In this example, a stereoscopic image is formed according to the procedure described below.

First, the manuscript 1 of the photograph (person image) shown in FIG.
From an electrophotographic copier (explained later with reference to FIG. 5) for transparent overhead projectors (OH
It is copied to a film (abbreviated as P) and a first copy image 2 shown in FIG. 2 is taken.

Next, the original 1 shown in FIG. 4 is rotated 90 degrees from the original position and the second copy image 3 shown in FIG. 3 is taken on the OHP film using the same copying machine as described above. Then, the first and second copy images 2 and 3 are superposed so that the images match each other to form a composite copy image 4 shown in FIG. The first and second copy images 2 and 3 are flat and do not show a stereoscopic effect,
The composite copy image 4 has a three-dimensional effect.

FIG. 5 is an internal front view showing the structure of the electrophotographic copying machine used for forming the first and second copy images 2 and 3.

In this copying machine 61, a glass original placing table 63 for placing the original 1 and a platen cover 64 for covering the original 1 are arranged on the upper part of the cabinet 62.

Below the document table 63, an optical scanning table composed of a light source 65 and a first mirror unit 67 having a first reflecting mirror 66 is provided so as to be linearly movable in the left-right direction in the drawing, and to serve as a document scanning point. The second mirror unit 68 for keeping the optical path length to the photosensitive member constant moves according to the speed of the first mirror unit 67, and the reflected light from the document table 63 side causes the lens 69, the reflection mirror 70A and the dichroic mirror. The light is incident on the photosensitive drum 71 serving as an image carrier via the slit 70B in a slit shape.

Around the drum 71, a corona charger 72, a developing device 74 with a developing sleeve 73, a transfer part 75A, and a separating part 75.
B, a cleaning unit 84 are arranged respectively, and a paper feed box 85
The OHP film 78, which is sent from the sheet feeding rollers 76 and 77, is further fixed in the fixing section 79 after the toner image on the drum 71 is transferred, and is discharged to the tray 83.

In the fixing section 79, a developed OHP is provided between a heating roller 81 having a heater 80 built-in and a pressure roller 82.
The fixing operation is performed through the film.

Since the composite copy image 4 of FIG. 1 has a stereoscopic effect, the image produced through the subsequent steps becomes a stereoscopic image. The reason why the composite copy image has a stereoscopic effect is shown in FIG. 6 and FIG. 7 will be described.

As shown in FIG. 6, when the exposure light 5 for illuminating the original 1 at the time of copying shifts from the relative dark portion to the relative light portion, for example, when shifting from the darkest portion D to the lightest portion L, The reflected light 6 from the boundary and the reflected light 6'transmitted through the lightest portion L and reflected from the upper surface of the reflected light make a line having a width d appear at the boundary in the copy image. The formation of lines at this boundary is undesired for general reproduction,
When a laser beam is used as the light source 65 of FIG. 5, it becomes particularly remarkable.

The line at the boundary appearing in the copy image gives a stereoscopic effect to the composite copy image. Therefore, it is advantageous for the method of the present invention to use the copying machine 41 which uses laser light as the light source 65. Is. Further, the scanning exposure with a laser beam is capable of high-density scanning exposure of 270 lines per 1 mm width, which is also preferable in terms of resolution.

FIG. 7 is a plan view schematically showing an enlarged shaded portion in the image for explaining the reason why the composite copy image has a three-dimensional effect.

FIG. 7A shows an example of the arrangement of white portions (lightest portions) L, black portions (darkest portions) D, and interstitial portions M in the image of the original 1.

FIG. 7B shows the same portion of the first copy image 2 as in FIG. 7A, and is to the right of the black portion D and the transparent portion T corresponding to the white portion L in FIG. A strong line appears at the boundary,
Weak lines appear on the right boundary between the intermediate portion M and the transparent portion T and between the black portion D and the intermediate portion M.

FIG. 7C shows the original 1 with respect to FIG.
Shows the same portion as the second copy image 3 copied at a position rotated by 90 degrees, and the appearance of the line is the same as in FIG.

The first copy image 2 of FIG. 7 (b) and FIG. 7 (c).
When the second copy image 3 of FIG. 3 is superposed so that the images coincide with each other to form the composite copy image 4 of FIG. 7D, the appearance of the line is as shown in the figure.

In the original 1, the concave portion of the subject becomes a shadow and becomes a dark portion (black portion D), and the convex portion becomes bright and becomes a light portion (white portion L). In the composite copy image 4, the difference in light and dark (difference between the black portion D, the intermediate portion M, and the transparent portion T) is microscopically emphasized by the above line, and a stereoscopic effect is shown. This three-dimensional effect causes three-dimensional unevenness due to image exposure, development and fixing on the photosensitive resin in the subsequent steps.

The following steps are carried out along the line AA, B in FIG.
A description will be given based on this light-dark pattern at the position of cutting the B line. In the following figures, the cross-sectional position along the line AA is shown in each figure (a).
The cross-sectional position along the line B-B is shown in each figure (b).

As shown in FIGS. 8A and 8B, the first,
The photosensitive resin 8 is covered with a composite copy image 4 formed by superimposing the second copy images 2 and 3, and image exposure is performed by exposure light 7 through the composite copy image 4. The photosensitive resin 8 is soft when it is not irradiated with light, and has a property of being cured according to the intensity of irradiation light when it is irradiated with light. Examples of such a resin include polyvinyl cinnamate and polyvinyl azidobenzal in which the exposed area is reinforced by a crosslinking reaction.

By the image exposure, the portion of the photosensitive resin 8 becomes a hard portion HA, a soft portion SO, and an intermediate portion MI between them in accordance with the light-dark pattern of the composite copy image 4. That is, this step is a latent image forming step. At the time of this image exposure, the first and second copy images 2 and 3 receive a considerable amount of heat, so that the transparent film carrying these copy images is preferably an OHP film having heat resistance. The OHP film can withstand the fixing temperature during copy image formation.

Next, the composite copy image 4 is removed and washed with running water while rubbing the photosensitive resin 8 with a brush, as shown in FIG.
Asperities are formed on the surface according to the degree of curing as shown in (b). That is, this step is a developing step.

Next, as shown in FIGS. 10 (a) and 10 (b),
When the entire surface is exposed with the exposure light 10, the photosensitive resin 8 is uniformly hardened to form the hard resin mold 9 having the irregularities shown in FIGS. 9 (a) and 9 (b). That is, this step is a fixing step. This whole surface exposure may be exposure with a halogen lamp, for example.

The hard resin mold 9 is used as a prototype of a later three-dimensional image. As shown in FIGS. 11 (a) and 11 (b), the paint 11 is applied to the uneven surface to give a predetermined color. Alternatively, it can be plated and used as a product.

To produce a three-dimensional image, FIG.
As shown in (b), a female die 13 made of a metal coating layer is formed on the uneven surface of the hard resin die 9. The female die 13 can be easily manufactured by metal spraying (metallikon). FIG. 19 is a schematic front view showing the procedure of the spraying, and the spray gun
16 using the molten resin 13a on the uneven surface of the hard resin mold 9
And the female mold 13 is produced.

Next, as shown in FIGS. 13 (a) and 13 (b),
Remove the hard resin mold (9 in Fig. 10) from the female mold 13, then
As shown in FIGS. 14 (a) and 14 (b), the metal 14A is sprayed to a concave surface of the female die 13 with a sufficient thickness, and after the female die 13 is removed, finishing is performed until a position indicated by an imaginary line in the drawing, A metal solid image 14B shown in FIGS. 15 (a) and 15 (b) is obtained.

Thus, a three-dimensional image 14B in which the image of the person who is the subject of the copied image (original document 1 of the photograph) of FIG. 4 is faithfully reproduced by the unevenness is produced. Then, a three-dimensional image is easily created by the above-mentioned work that does not require skill. Further, the female mold 13 from which the hard resin mold 9 is removed can be repeatedly used, and a large number of identical stereoscopic images can be produced.

In addition to the above-mentioned three-dimensional image 14B, a three-dimensional image due to unevenness can be formed by embossing on paper.

As shown in FIGS. 16 (a) and 16 (b),
When the thick paper 15A is applied to the concave side of the female die 13 and pushed as indicated by the arrow, the paper 15A is deformed in close contact with the concave surface of the female die 13 as shown in FIGS. 17 (a) and 17 (b). It becomes paper (relief) 15B. Then, the female mold 13 is removed to obtain a relief 15B in which a three-dimensional image shown in FIGS. Figure from Figure 16
Processing to 17 is easily performed by the usual embossing.

FIG. 20 is a perspective view of a medal with a three-dimensional portrait produced by the process of FIG. 15, and FIG. 21 is an enlarged perspective view of a similar golf marker. Such a medal or a marker has a high subjective value by providing a three-dimensional portrait of the owner and by making a precious metal such as gold or silver. Also, for example, a set of medals with three-dimensional portraits of successive US presidents is objectively valuable.

FIG. 22 is an enlarged perspective view of the hard resin marker manufactured by the process of FIG. 11, and by providing a three-dimensional portrait of the golf player, the golf player will be pleased with the player.

In these figures, 17 is a medal, 18 and 19 are markers, 17a, 18a and 19a are discs, 17b, 18b and 19b are three-dimensional portraits provided on the discs, and 18c and 19c are fixing pins. Is.

FIG. 23 shows a business card 20 made of a relief having a portrait 20a in the corner. The business card 20 has a better impression than a business card in which the photograph of the person is printed in the corner.

<Embodiment 2> In this example, the second copy image is formed at a position where the original is rotated by 60 degrees with respect to the position of the original at the time of forming the first copy image, and the original is further read from this position. This is an example in which a third copy image is formed at a position rotated by 60 degrees. The other steps are the same as those in the first embodiment.

FIG. 7 is a composite copy image 24 formed by superimposing 23A and 23B.
It is a figure similar to (d).

FIG. 25 is a sectional view similar to FIG. 8, showing a state in which the photosensitive resin 8 is image-exposed through the composite copy image 24.

In this example as well, the composite copy image 24 shows the same stereoscopic effect as the composite copy image 4 of the first embodiment. Therefore, after that, through the same steps as the steps of FIGS. 8 to 19 of the first embodiment, the medal 17 shown in FIG. 20, the markers 18, 19 shown in FIG. 21, and the business card shown in FIG. 20 are made.

It goes without saying that this example also has the same effects as in the first embodiment.

<Embodiment 3> This embodiment and Embodiment 4 described later

The cross-sectional position along the line B-B is shown in each figure (b).

As shown in FIGS. 30 (a) and 30 (b), the first,
The photosensitive resin 38 is covered with a composite copy image 34 formed by superimposing the second copy images 32 and 33, and image exposure is performed by the exposure light 7 through the composite copy image 34.

By the image exposure, the photosensitive resin 38 becomes a hard portion HA, a soft portion SO, and an intermediate portion MI between them in accordance with the light-dark pattern of the composite copy image 34, and a latent image is formed.

Next, the composite copy image 34 is removed, and the photosensitive resin 38 is washed with running water while rubbing the photosensitive resin 38 with a brush, that is, when it is developed, the degree of curing is as shown in FIGS. 31 (a) and 31 (b). Corresponding unevenness is formed on the surface. This uneven pattern is the reverse of the uneven pattern of FIG. 9 of the first embodiment.

Next, as shown in FIGS. 32 (a) and 32 (b),
When the entire surface is exposed with the exposure light 10, the photosensitive resin 8 is uniformly hardened and fixed to form the hard resin mold 39 having the unevenness shown in FIGS. 31 (a) and 31 (b).

Next, a mold is produced in which the concavo-convex pattern of the hard resin mold 39 is faithfully reproduced. This mold can be easily manufactured using a copy engraving machine. In this example, the copy engraving machine is a small three-dimensional engraving machine model S manufactured by Hoken Co., Ltd.

A metallic solid image 41B such as a medal shown in 35 (a) and (b).
And

The mold 40 is excellent in durability and can be repeatedly used, and it is possible to produce many identical three-dimensional images from a single mold.

In addition to the above-described three-dimensional image 41B, a three-dimensional image due to unevenness can be formed by embossing on paper.

As shown in FIGS. 36 (a) and 36 (b),
When the thick paper 15A is applied to the concave side of the mold 40 and pushed in the direction of the arrow, the paper 15A is deformed in close contact with the concave side of the mold 40 as shown in FIGS. 37 (a) and 37 (b). It becomes paper (relief) 15B. Next, this is removed from the mold 40, and FIG. 18 (a),

As described above, in the same manner as in the first embodiment, the medal 17, the markers 18 and 1 shown in FIGS.
9 、 Business card 20 is made. Even in this example, the same effect as in the first embodiment can be obtained. Besides, the mold
40 is more durable than a female mold made by metal spraying, and is more advantageous for producing many identical stereoscopic images.

<Embodiment 4> In this example, a second copy image is formed at a position where the original is rotated by 60 degrees with respect to the position of the original at the time of forming the first copy image, and the original is read from this position. This is an example in which a third copy image is formed at a position rotated by 60 degrees. The other steps are the same as those in the first embodiment.

FIG. 38 is an enlarged schematic plan view similar to FIG. 29 in the third embodiment, showing the shaded portion in each image.

FIG. 38A is exactly the same as FIG. 29A of the original 31. FIG. 38 (b) is exactly the same as FIG. 29 of the first copy image 32. 38 (c) and 38 (d) are second and third copied images.
29A is a view similar to FIG. 29C of FIGS. 43A and 43B, but in this example, the second copy image 43A is copied at a position rotated by 60 degrees with respect to the original position when the first copy image 32 is formed. And a third copy image 43B at a position further rotated by 60 degrees is formed. Figure
38 (e) is the first copy image 32 and the second and third copy images 43A,
FIG. 30 is a cross-sectional view similar to FIG. 29 (d) of the composite copy image 44 formed by superimposing 43B.

FIG. 39 shows the photosensitive resin through the synthetic copy image 44.
FIG. 31 is a sectional view similar to FIGS. 8, 25 and 30 showing a state where image exposure is performed on 38.

In this example as well, the composite copy image 24 optically exhibits the same stereoscopic effect as the composite copy image 34 of the third embodiment. Therefore, after that, through the same steps as the steps of FIG. 29 to FIG. 37 of the third embodiment, the medal 17, FIG.
The markers 18 and 19 shown in FIG. 22 and the business card 20 shown in FIG. 23 are produced.

It goes without saying that this example also has the same effects as in the third embodiment.

<Embodiment 5> In this example, when the first and second copy images are formed, the exposure of the image on the photosensitive drum is not performed by directly irradiating the image reflected by the original on the photosensitive drum. This is an example in which the reflected light from is converted into a signal suitable for recording and recorded, and dot exposure is performed on the photoconductor drum by laser light based on the recorded information.

FIG. 40 is an internal front view showing the structure of the electrophotographic copying machine 91 configured as described above. It should be noted that portions common to FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted.

The reflected light from the original 1 is converted into an electric signal by the image pickup device 92, converted into a digital signal by the input side image processing section 93, and input to the output side image processing section 94 and the CPU (central processing unit). Input side image processing unit 93 and CP
The output side image processing unit 94, to which the signal from U is input, outputs a digital signal for driving the laser optical system 95.

With this signal, the laser optical system 95 scans and exposes the photosensitive drum 71 corresponding to the image of the original 1. The scanning exposure L has a dot shape. The electrostatic latent image formed on the photosensitive drum 71 by this dot-shaped scanning image exposure is developed by the developing device 96 into a visible image, and this visible image is transferred to the OHP film 78, fixed and discharged. To be paper. Since the three-dimensional information of the original can be recorded by the dot image exposure, a three-dimensional image can be formed with one OHP film. This type of copying machine generally uses a reversal development method in which toner adheres to the exposed photosensitive drum portion.

The copying machine 91 of FIG. 40 is used, and FIGS.
24, FIG. 25, FIG. 26 to FIG. 37, FIG. 38, and FIG. 39, in the same manner as in Embodiments 1 to 4, the medal 17 shown in FIG. 20 and the marker 18 shown in FIG. 21 and FIG. , 19, the business card 20 shown in FIG. 23 is produced.

In this example, the same effects as those of the first to fourth embodiments are obtained, and the output signal of the output side image processing unit 94 is stored, and thereafter, a stereoscopic image is formed without a document. It has the advantage that it can be formed. Further, the stored signal can be sent from a remote place via a telephone line to perform image exposure.

<Embodiment 6> Using the copying machine 91 shown in FIG. 40, it is possible to form a three-dimensional image faithful to a full-color original with only one copy image. In addition to the developing machine 96, developing machines 97 and 98 indicated by imaginary lines are provided. Photoconductor drum 71
Image exposure is performed with monochromatic light of the three primary colors of light, red, green and blue. Such image exposure can be easily performed based on the image information obtained by the image processing. For development, three developing machines 96, 97 and 98 are used to develop the toners of cyan, magenta and yellow which are the three primary colors of subtractive color mixture. Thus, a full color copy image is formed on the OHP film.

In a full-color copy image, various colors appear in minute areas, so that the boundary between areas having different colors becomes clear, and one copy image has the first and second image information (first, The image information of the second copy image) is recorded, which makes it possible to form a more faithful stereoscopic image on the original. The subsequent steps are the same as those in Examples 1 and 3.

<Embodiment 7> This example is an example in which the copier of FIG. 40 is slightly modified to directly perform image exposure on the drum-shaped photosensitive resin without using the OHP film.

FIG. 41 is an internal front view showing the structure of the copying machine according to this example. In this copying machine 101, instead of the photosensitive drum 71 of FIG. 40, a photosensitive resin 48 wound around a support 47 having a circular cross section is provided. Imagewise exposure is carried out, and development and fixing are carried out in the same manner as described above to prepare a drum-shaped mold having a pattern similar to that of the hard resin molds 9 and 39 shown in FIGS.

FIG. 42 shows the procedure for producing a female die by spraying using the drum-shaped die 49 produced as described above. The hard resin mold 49 is removed from the copier together with the support 48, and sprayed with a spray gun while rotating to form a metal female mold 50. Figure 43 shows the cylindrical female mold 50 removed from the support.
Indicates. A concave-convex pattern is formed on the inner peripheral surface of the female die 50.

Next, as shown in FIG. 44, the spray gun 16 is installed inside the female die 50, and is sprayed on the inner peripheral surface of the rotating female die 50. A male mold 51 is produced. Then, in the same manner as in each of the above examples, the medal 17 shown in FIG.
21, the markers 18 and 19 shown in FIG. 22 and the business card 20 shown in FIG. 23 are manufactured (110 in the drawing is a processed paper, 111 is a roll).

Although the embodiments of the present invention have been described above, various modifications can be added to the above-described embodiments based on the technical idea of the present invention.

For example, using the copying machine shown in FIG. 5, the reversal development button is operated to form a negative copy image from a positive document.
Alternatively, a positive copy image can be formed from a negative original. Similarly, by using the copying machine shown in FIG. 40, a button for normal development can be operated to form a negative copy image from a positive document or a positive copy image from a negative document.
In this way, it is possible to appropriately combine the two types of originals and the two types of developing methods.

As the photosensitive resin, in addition to the above-mentioned polyvinyl cinnamate and polyvinyl azidobenza, a resin which is softened by irradiation with light, or a negative type acrylamide which becomes insoluble by photopolymerization or a quinonediazide group is photolyzed. A positive-type o-quinonediazido novolac resin, which forms a carboxylic acid and becomes easily soluble, can be used. In addition to the resin, it is possible to replace the photosensitive glass, which has a faster dissolution rate in hydrofluoric acid by light irradiation, with a photosensitive resin.

Further, as the three-dimensional image, in addition to the medal, the golf marker and the business card described above, the three-dimensional image can be formed by embossing the three-dimensional image on the jewelry container, the accessory, the miscellaneous goods and various cards by the method of the present invention. .

According to the present invention, the first image information and the second image information at the position rotated by a predetermined angle with respect to the first image information are superposed to form the combined image information. The unevenness of the original image is three-dimensionally recorded in this composite image information.
Therefore, a latent image is formed by imagewise exposing the photoconductor on the basis of the composite image information, and by developing the latent image, a stereoscopic image faithful to the original image is formed.

Furthermore, the formation of the above-mentioned three-dimensional image does not require special skill using an electrophotographic copying apparatus, and a large number of three-dimensional images can be formed at high speed and at low cost.
