BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming plate capable of producing a desired image on a viscous fluid.

[0002]

2. Description of the Related Art Conventionally, there are known daylight photography devices that print a film image on photographic paper, but there is no image forming plate capable of causing an image such as a film to appear in a viscous fluid that emits sunlight. It was

SUMMARY OF THE INVENTION The object of the present invention is to allow a desired image to appear in a sunlight-coloring viscous fluid by the irradiation of sunlight, and to make the image appearing in the viscous fluid form an air pool. Easy to erase by spreading by moving bubbles
It is to provide an image forming plate capable of

[0004]

In order to achieve the above-mentioned object, the image forming plate of the present invention is formed between a front plate 3 and a back plate 2 of a transparent flat hollow plate 1 through which sunlight can pass. The flat interior chamber 4 is filled with a sunlight-coloring viscous fluid 5 that leaves the air pool 6 and develops a color by the irradiation of sunlight, and naturally disappears when moved to a place not exposed to the sunlight and left to stand. A desired image can be formed on this viscous fluid.

[0005] The viscous fluid 5 is a highly viscous fluid which is mixed spiropyran (photochromic a color former), for example, liquid paraffin, a flat interior 4 of the hollow plate 1 you sealed leaving an air reservoir 6.

[0006]

The image forming plate having the above-described structure is a positive film F (for example, an appropriate shaped body in which the modeling portion serves as a light-shielding portion) on the surface plate 3 of the flat hollow plate 1 having the image portion 10 serving as a light-shielding portion. May be present), and the film F or the flat hollow plate 1 on which the shaped body is placed is placed in a place exposed to sunlight and irradiated for a certain period of time, for example, for about 30 seconds, to obtain a film image 10 of the viscous fluid 5. Alternatively, the irradiated portion 5a which is not shielded by the image of the shaped object develops, for example, reddish purple, and the viscous fluid 5
The light-shielded portion of the film image 10 or the image of the molded body is formed as a white transferred image 11 that does not change color, and the white transferred image 11 appearing in the viscous fluid 5 is used as the film F or the molded body. Can be removed for perspective.

The image 11 appearing in the viscous fluid 5 is
When the hollow plate 1 is moved to a place not exposed to sunlight and left to stand, the color of the viscous fluid 5 disappears and is naturally erased. However, if an air pocket 6 is formed in the viscous fluid 5, it becomes thick.
Without shifts left in place not exposed sunlight, diffused appearance image 11 of the viscous fluid 5 it can be easily erased in bubble movement of the air reservoir 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a transparent flat hollow plate through which sunlight can pass, and the flat hollow plate 1 has a fitting edge 2a and an injection port 2.
A transparent synthetic resin back plate 2 having b, and a transparent synthetic resin front plate 3 fitted and bonded to a fitting edge portion 2a of the back plate 2.
A flat inner chamber 4 having a width of about 2 mm is formed between the front plate 3 and the back plate 2.

5 is a viscous fluid of a sunlight-developing color which is enclosed in the flat inner chamber 4 of the hollow plate 1 leaving an air reservoir 6 (a color is generated when the sunlight is irradiated for a certain period of time, for example, about 30 seconds, and is not exposed to the sunlight. It is a viscous fluid that loses its color spontaneously when moved to a place and left in the place. In the case of this example, a suitable amount of spiropyran (photochromic which is a color former) is mixed in liquid paraffin to produce a reddish violet color when irradiated with sunlight. A cap 7 screwed into the inlet 2b by applying a highly viscous liquid
Sealed to prevent leaks.

The surface plate 3 of the hollow plate 1 is provided with a film positioning recess 3a and a projection 3b for locking the transparent film pressing sheet 8 by hole fitting.

Film positioning recess 3a of the surface plate 3
The film F to be superposed on the inside is a positive film formed by printing or photo-printing the light-shielding image portion 10 on a transparent sheet, for example, and is a film positioning recess 3a.
The sheet is held by the film pressing sheet 8 as shown in FIG.

Then, the positive film F having the image portion 10 as a light-shielding portion is superposed on the surface plate 3 of the hollow plate 1, and the flat hollow plate 4 on this film is exposed to sunlight. When placed in a place as shown in FIG. 1 and irradiated for a certain period of time, for example, for about 30 seconds, the irradiated portion 5a which is not shielded by the film image 10 of the viscous fluid 5 develops a reddish purple color and is shielded by the film image 10 of the viscous fluid 5. 3 is formed as a white transferred image 11 that does not change color, as shown in FIG. 3, and the white transferred image 1 that appears in the viscous fluid 5 is formed.
1 can be seen through by removing the film F.

In the above embodiment, the case where the film image 10 is made to appear in the viscous fluid 5 has been described. Instead of the positive film F, the image portion 10 is a blank image and the other film surface is a light shielding portion. It is also possible to use a negative image film described above. In this case, since the portion of the viscous fluid 5 corresponding to the film image 10 develops a reddish purple color, a discolored image opposite to the white transfer image 11 shown in FIG. Can be formed.

If an appropriate flat plate shaped body (not shown) having a shaped portion as a light-shielding portion is placed on the surface plate 3 of the hollow plate 1 instead of the film F, this shaped body It is also possible to cause the image to appear on the viscous fluid 5 as a white transferred image 11.

[0016]

The image forming plate of the present invention is such that the viscous fluid as described above is enclosed in the flat inner chamber of the flat hollow plate while leaving an air reservoir, so that it is desirable for a viscous fluid that is capable of producing sunlight. The image can be made to appear by the irradiation of sunlight, and the image that appeared in the viscous fluid can be moved by moving bubbles in the air pool.
Ru can be erased easily diffused.

Claims (1)

[Scope of utility model registration request] 1. A flat inner chamber formed between a front plate and a back plate of a transparent flat hollow plate through which sunlight can pass, and is transferred to a place where it is colored by the irradiation of sunlight and is not exposed to the sunlight. The image forming plate is characterized in that a viscous fluid that develops sunlight, which naturally loses its color when left unattended, is enclosed in an air pocket so that a desired image can be formed on this viscous fluid.
