(Examples) Hereinafter, with reference to the accompanying drawings, an XYZ plotter of the present invention, that is, a fly's eye lens, a photosensitive recording member installed on the focal plane of the fly's eye lens, and the fly's eye described above. XYZ comprising means for three-dimensionally displacing a point light source turned on at a position corresponding to the shape of the three-dimensional image to be recorded in the three-dimensional space in front of the lens.
The specific contents of the plotter will be described in detail.

FIG. 1 is a perspective view showing a schematic configuration of an XYZ plotter of the present invention, FIG. 2 is an explanatory view of a recording principle of a three-dimensional image by the XYZ plotter of the present invention, and FIG. 3 is recorded by the XYZ plotter of the present invention. It is explanatory drawing of the reproduction | regeneration principle of a three-dimensional image.

In FIG. 1, MB is a machine base, and a fly's eye lens (on the machine MB is similar to an insect compound eye composed of a large number of individual eyes, Eye lens, a lens with a commonly used configuration such as a lens) F
EL and a photosensitive recording member PSM arranged so as to be located on the focal plane of the fly-eye lens FEL are installed.

The fly-eye lens FEL described above has a minute diameter, for example, 0.
As a plurality of individual lenses having a diameter of 5 mm to 0.07 mm and a short focal length, or as a configuration form in which they are arrayed and assembled, for example, one configured as a molded product of transparent plastic can be used.

The fly-eye lens FEL has a configuration in which a large number of individual lenses are arranged in a predetermined arrangement pattern, as shown in FIG. In addition to the above, for example, as shown in FIG. 4, two cylindrical convex lens arrays CLA are used.
1 and CLA2, each of the above cylindrical, convex lens,
It is also possible to use a configuration in which the cylindrical lens axes of the arrays CLA1 and CLA2 are arranged in series in the optical path in a state of being arranged so as to be orthogonal to each other to form a fly-eye lens.

In FIG. 4, PSM (PSMp) is a photosensitive recording member (or recorded photosensitive recording member), and this photosensitive recording member PSM (or recorded photosensitive recording member PS).
Mp) is arranged on the focal planes of both of the two cylindrical / convex lens arrays CLA1 and CLA2 that compose the fly's-eye lens FEL.

As the photosensitive recording member PSM, for example, a photographic plate or a photographic film provided with a silver salt photosensitive material film is used, or a phase change from an amorphous state to a crystalline state by irradiation of light or A photosensitive recording member that causes a phase change from a crystalline state to an amorphous state, a magneto-optical recording member, or the like can be used, but in the following description of the embodiments, silver is used as the photosensitive recording member PSM. It is said that a photographic dry plate or a photographic film provided with a salt photosensitive material film is used.

Then, the XYZ plotter of the present invention is displacement-driven so that it can be turned on in the three-dimensional space in front of the fly-eye lens FEL at a position corresponding to the shape of the three-dimensional image to be recorded. The point light source PPS is provided, and the entire configuration is used in a dark box.

The above-mentioned point light source PPS to be configured so as to be capable of being displaced and driven to any position within a predetermined range in a three-dimensional space in front of the fly-eye lens FEL.
In the configuration of the XYZ plotter shown in FIG. 1, the displacement is driven by the drive unit DRA provided on the machine base MB.

That is, the point light source P in the XYZ plotter shown in FIG.
The drive device DRA of the PS is a transfer body in the X-axis direction that is transferred in the X-axis direction along a rail member Rx provided so as to extend in the X-axis direction in the XYZ orthogonal coordinate system by the drive rotation of the stepping motor Mx. Fx and the transfer member Fx in the X direction described above, along the rail member Rz provided so as to extend in the Z axis direction in the XYZ orthogonal coordinate system, along the Z axis direction by the driving rotation of the stepping motor Mz. Along the Z-axis transfer body Fz that is transferred to the Z-axis direction and the rail member Ry that is fixed to the Z-axis direction transfer body Fz and that is provided so as to extend in the Y-axis direction in the XYZ orthogonal coordinate system. And a transfer body F in the Y-axis direction that is transferred in the Y-axis direction by the driving rotation of the stepping motor My.
and y.

Then, the point light source PPS in the XYZ plotter of FIG.
The drive device DRA of FIG. 2 is such that the stepping motors Mx, My, Mz of the respective transport bodies Fx, Fy, Fz in the X, Y, Z axis directions are rotationally driven according to drive signals supplied from the computer. By the point light source PPS fixed to the transfer body Fy in the Y-axis direction.
However, it can be driven to be displaced to any position within a predetermined range in the three-dimensional space in front of the fly-eye lens FEL, and the lighting state of the point light source PPS is controlled by a computer. , Within the predetermined range in the three-dimensional space in front of the fly-eye lens FEL, the shape of the three-dimensional image to be recorded is displayed as a continuous linear light trajectory. Alternatively, the shape of the three-dimensional image to be recorded may be displayed by the array of light spots.

Now, when the point light source PPS is turned on in the three-dimensional space in front of the fly's eye lens FEL, the light emitted from the point light source PPS is the fly's eye lens as illustrated in FIG. (Compound eye lens) On the photosensitive recording member PSM installed on the focal plane of the FEL, an image of the point light source PPS is formed and recorded for each individual lens (single eye lens) in the compound eye lens FEL. In FIG. 2, a portion indicated by a circle on the photosensitive recording member PSM arranged so as to be located on the focal plane of the fly's eye lens FEL is a three-dimensional space in front of the fly's eye lens FEL. 3 shows an image forming portion of the image of the point light source PPS in FIG.

A fly-eye lens (compound-eye lens) F when the lighting position of the point light source PPS moves to a different position from the second illustrated position in the three-dimensional space in front of the fly-eye lens FEL.
With respect to the photosensitive recording member PSM installed on the focal plane of EL, the moved point light source PPS is formed into an image for each individual lens (single eye lens) in the compound eye lens FEL described above.
Needless to say, the image of is different from the image forming position of the image of the point light source PPS described above in the second illustration, and therefore, it is installed on the focal plane of the fly's eye lens (compound eye lens) FEL. In the photosensitive recording member PSM, the lighting position of each point light source PPS in the three-dimensional space in front of the fly's eye lens FEL is set to 1 for each individual lens (single lens) in the compound eye lens FEL. Since the image of the point light source PPS is formed and recorded at the position corresponding to the pair 1, the fly-eye lens FEL is formed on the photosensitive recording member PSM.
The position information of the point light source PPS is recorded for each position three-dimensionally displaced in the three-dimensional space in front of the.

In the recording mode as described above, a fly's eye lens (compound eye lens) F
If the photosensitive recording member PSM is a positive type, the image of the point light source in the three-dimensional space in front of the fly's eye lens FEL recorded on the photosensitive recording member PSM installed on the focal plane of the EL is By developing it, only the image portion of the point light source becomes transparent and the other portion becomes black, so that the image is developed.

FIG. 3 shows that the recorded photosensitive recording member PSMp on which the position information of the point light source PPS located in the three-dimensional space in front of the fly's eye lens FEL is recorded as described above is irradiated with scattered light. FIG. 3 is a diagram for explaining that a reproduced image PPSp of the original point light source PPS can be made to appear in the space in front of the fly's eye lens FEL. In FIG. 3, PSMp is an image of the point light source. This is the recorded photosensitive recording member PSMp which has been developed in such a manner that only the above portion becomes transparent and the other portions become black.

The above-mentioned recorded photosensitive recording member PSMp and the fly's-eye lens FEL having the same configuration as the fly's-eye lens FEL used at the time of recording have the same relative positional relationship as those at the time of recording. And the recorded photosensitive recording member PS from the side opposite to the fly-eye lens FEL.
When Mp is irradiated with scattered light from the light source DSP, the light transmitted through the recorded photosensitive recording member PSMp becomes the fly's eye lens FE.
By collecting light by each individual lens (single-eye lens) in L, a real image is formed on PPSp in the three-dimensional space in front of the fly's-eye lens FEL as illustrated in FIG. The real image PPSp of is viewed by a person who is located away from the position of the real image PPSp, and is perceived as a point of light existing at the position of the real image.

Then, if the image of the point light source PPS at each of a number of three-dimensionally displaced positions in the three-dimensional space is recorded as the recorded photosensitive recording member PSMp, the recorded photosensitive recording member PSMp is recorded. The image at each position of the point light source PPS that has been formed is condensed by each individual lens (single eye lens) in the fly's eye lens FEL, and the original image in the three-dimensional space in front of the fly's eye lens FEL is collected. Since a real image is formed at each point light source position of
When viewed by a person who is away from the position of Sp, the entire light line or light point appearing at the position of the real image in the three-dimensional space can be perceived as a three-dimensional image by light.

As is clear from the principle of recording / reproducing described with reference to FIGS. 2 and 3, the XYZ plotter of the present invention performs line drawing by light or point drawing by light by lighting a point light source in a three-dimensional space. Since the three-dimensional image by the drawn light is recorded on the photosensitive recording member installed on the focal plane of the fly's eye lens, a three-dimensional image by a color image can be obtained by selectively using the point light source and the photosensitive recording member. It is also possible to make a three-dimensional image appear.

Also, instead of a light transmissive type as a recorded photosensitive recording member, a light reflecting type recorded photosensitive recording member (for example, photographic paper) is used to illuminate with diffused light from the fly's eye lens side during reproduction. However, in the three-dimensional space in front of the fly's eye lens, a three-dimensional image by light drawn as line drawing by light or dot drawing by light can appear.

The photosensitive recording member PSM to be arranged so as to be positioned on the focal plane of the fly's eye lens FEL may be integrated with the fly's eye lens FEL, or may be the fly's eye. The photosensitive recording member PSM and the fly's-eye lens F to be arranged so as to be located on the focal plane of the lens FEL.
It may be configured separately from the EL.

In the case where the photosensitive recording member PSM to be arranged so as to be located on the focal plane of the fly's-eye lens FEL is configured separately from the fly's-eye lens FEL,
The recorded photosensitive recording member PSMp and the fly's eye lens F having the same configuration as the fly's eye lens FEL used at the time of recording.
It is needless to say that they should be combined and used for reproduction so that the relative positional relationship between them and EL is the same as that at the time of recording.

(Effects) As is apparent from the detailed description above, the XYZ plotter of the present invention is a fly-eye lens, a photosensitive recording member installed on the focal plane of the fly-eye lens, and the fly. The point light source that can be displaced and turned on in the three-dimensional space in front of the eye lens, and the shape of the three-dimensional image based on the computer data to be recorded are described above according to the movement locus of the point light source. As shown in a three-dimensional space, the point light source is provided with a displacement driving means for three-dimensionally displacing the point light source. Therefore, the XYZ plotter of the present invention has a simple structure, High quality 3
It is possible to easily provide a hard copy that allows a three-dimensional image to be easily drawn in a three-dimensional space as a line drawing or a dot drawing. According to the present invention, the above-mentioned conventional problems can be solved satisfactorily. it can.
