Abstract

PROBLEM TO BE SOLVED: To vary the color of an ornament at low cost using an inexpensive material having optically active properties which can be easily prepared by injection molding and punching. SOLUTION: A polarizing plate 2, a turntable 5, a polarizing plate 1, and a white light source 3 are disposed in a row as seen from an observer 6. The polarizing plates 1, 2 are set at right angles to the direction of the axis of polarization. A colorless and transparent three-dimensional ornament 4 made from a material having optically active properties is placed on a turntable 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a colorless transparent three-dimensional figurine made of a material having optically active properties, which transmits polarized light to give a color to the figurine and turns the figurine on the figurine. The present invention relates to an apparatus that changes the color of an ornament by rotating a table, and that changes the color of the ornament using polarized light.

[0002]

2. Description of the Related Art Conventionally, most figurines such as dolls, models, and pottery are colored in advance, and the color changes over time with fading or fading, but from red to green and blue in a short time. Various color changes such as yellow do not occur. As a device for changing the color of a figurine, there is a mood lamp that produces a figurine such as a flower or a bird using optical fibers as a material and changes the color of light passing through the optical fiber to thereby change the color of the figurine.

[0003]

This has the following disadvantages. (A) The ornaments that have been painted in advance get tired of looking at them. (B) In an ornament made of optical fibers, the optical fibers of the material are expensive. (C) When an ornament made of optical fibers is used as an ornament,
It is not permissible to damage or cut off the optical fiber in the middle,
There are many restrictions on molding, and advanced technology is required.

[0004] The present invention can be manufactured by an easy method such as injection molding or die-cutting molding using a material having optically active properties such as inexpensive cellophane, polyester, PET resin, etc. It is an object of the present invention to provide a device for changing the temperature.

[0005]

(A) From the viewpoint of the observer (6), the polarizing plate (2), the turntable (5), the polarizing plate (1), and the white light source (3) are arranged in this order. Set up in a line. (B) The polarizing plate (1) and the polarizing plate (2) are installed such that the directions of the polarization axes are orthogonal to each other. (C) A colorless, transparent, three-dimensional object (4) made of a material having optical activity such as cellophane, polyester, PET resin, etc. is placed on a turntable (5). This is an apparatus for changing the color of an ornament using polarized light having the above configuration.

[0006]

Embodiments of the present invention will be described below. This will be described with reference to the drawings. The drawing shows a state in which an observer (6) is located on the right side of the apparatus and looks to the left and sees the ornament (4) through the polarizing plate (2). (A) When viewed from the observer (6), the polarizing plate (2), the turntable (5), the polarizing plate (1), and the white light source (3) are arranged in a line in this order. (B) The polarizing plate (1) and the polarizing plate (2) are installed such that the directions of the polarization axes are orthogonal to each other. (C) A colorless, transparent and three-dimensional figurine (4) made of a material having optical activity such as cellophane, polyester, PET resin, etc. by a method such as injection molding or die cutting. 5) Place on top. The above is the basic configuration of the present invention. To use the invention, the white light source (3) is first turned on. Then, the light passes through the polarizing plate (1) ornament (4) and the polarizing plate (2) and reaches the eyes of the observer (6). At this time, light refracts, reflects and interferes in the material of the ornament (4). Due to this phenomenon, the components of various colors contained in the white light are strengthened in a certain color, weakened in a certain color, and are observed by the observer (6) as if the color arrived on the colorless and transparent figurine (4). appear. Next, when the turntable (5) is rotated, the ornament (4) placed on the turntable (5)
Also rotates, the path length of the light transmitted through the material of the object (4) changes, and the color components that strengthen each other change according to the length. Thus, the observer (6) looks as if the color of the ornament (4) is variously changed while the ornament (4) is rotating.

[0007]

FIG. 2 shows an embodiment of the present invention. (A) two polarizing plates (1, 2) and colorless and transparent acrylic,
A square tubular case (11) without a bottom plate is made of a plastic plate such as vinyl chloride. The polarizing plate (1) is a partition of the case (11), and a light reflecting plate (7) is incorporated on the back surface of the polarizing plate (1). (B) The case base (12) is made of a wooden plate or a colored plastic plate. This case stand (12)
Then, a white light source (3) such as an incandescent lamp or a fluorescent lamp is attached, and a turntable (5) that rotates using a motor, a mainspring or the like is incorporated. (C) A colorless, transparent and three-dimensional figurine (4) made of a material having optical activity such as cellophane, polyester, PET resin, etc. by a method such as injection molding or die cutting. 5) Place on top. (D) Put the case (11) on the case stand (12). The above is the configuration of the embodiment of the present invention. When using
Insert the plug (10) into the outlet, and turn on the white light source switch (8) and the turntable switch (9). Then, the observer (6) looks as if the color of the ornament (4) is changing in various ways.

[0008]

According to the present invention, it is possible to provide a figurine whose color can be variously changed in a short time, which has not been achieved in the past. Moreover, the figurine can be manufactured with a cheaper material than the figurine using the optical fiber and by an easy method such as injection molding, die-cutting molding, etc., and the production cost can be reduced. Furthermore, cellophane paper, polyester film, and the like are easily available in ordinary households, and individuals can freely and easily make figurines such as origami, paper craft, and art flowers using these materials.
