DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lantern used for toys, indoor and outdoor decorations, advertisements, and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 8 and 9, a light source 2 arranged on a base 1, a rotating image body 3 surrounding the light source 2, and a rotating image body 3 surrounding the rotating image body 3 are shown. A lantern consisting of a projection body 4 arranged in a circle is known, and is used for toys, indoor and outdoor decorations, advertisements, and the like, for example.

[0003]

However, in the above-mentioned conventional lantern, the center of rotation of the rotating image body 3 and the center of the projection body 4 are arranged concentrically as shown in FIGS.

Accordingly, the image of the rotating image body 3 reflected on the projection body 4 moves only in the rotation direction, and it is not possible to obtain a variety of images.

The rotation center of the rotating image body 3 and the projection body 4
Are arranged concentrically with each other, so that the rotating image body 3 and the projection body 4 are arranged at a certain interval over the entire circumference between them, thereby preventing the two from coming into contact with each other. In. Therefore, there is a problem that the image of the rotating image body 3 reflected on the projection body 4 is blurred and not clear.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a light source disposed on a base, a rotating image member disposed around the light source, and In a turning lantern comprising a projection body arranged around an image body, the rotation center of the rotating image body and the center of the projection body are eccentric.

[0007] Where the center of rotation of the conventional rotating image body and the center of the projecting body are concentric, the image of the rotating image body projected on the projecting body shifts only in the rotating direction. By decentering the rotation center of the image object and the center of the projection object, the image of the rotation image object projected on the projection object changes not only in the rotation direction but also in the front-back direction.

Further, by decentering the rotation center of the rotating image body and the center of the projection body, the rotating image body on the eccentric side and the projection body can be arranged close to each other. , A very clear image can be projected.

Further, in the above-mentioned solution means, by providing a plurality of rotating image bodies, a more varied image can be obtained.

[0010]

Embodiments of the present invention will now be described with reference to the drawings.

FIGS. 1 and 2 show a preferred embodiment of the present invention, in which a light source 2 composed of a bulb 22 mounted on a socket 21 erected on a disk-shaped base 1 is shown. The base 1 is located around the light source 2
A cylindrical projection body 4 erected, for example, made of a translucent and appropriately hard synthetic resin material is arranged.

A cylindrical rotating image body 3 formed of a suitable hard synthetic resin material between the light source 2 and the projection body 4 and having an image drawn by a light-shielding portion, a light-transmitting portion and a semi-light-transmitting portion. Is arranged.

The center O of the projection body 4 is concentric with the center point P of the base 1, and the center Q of the light source 2 is not concentric with the center P of the base 1 and the projection body 4 but is eccentric. The rotation center R of the rotating image body 3 is arranged concentrically with the center Q of the light source 2.

A disc-shaped top wall 6 is provided on the top surface of the projection body 4, and the rotating image body 3 can be rotated on a rotating shaft 7 vertically provided on the lower surface of the top wall 6. The rotating image body 3 is rotated via a speed reducer 9 by a motor 8 disposed on the upper surface of the top wall 6, and the light of the light source 2 that has transmitted the image of the rotating image body 3 is projected onto the projection body 4. The image is projected on the screen.

In particular, in the present embodiment, the center of rotation of the rotating image body 3 and the center of the projection body 4 are decentered,
The image of the rotating image body 3 projected on the projection body 4 changes not only in the rotating direction but also in the front-back direction.

Also, the rotation center R of the rotating image body 3 and the center P of the projection body 4 are decentered, so that the rotating image body 3 is brought closer to the projection body 4 at the eccentric side portion 41 of the projection body 4. , And a very clear image can be displayed in this portion 41.

In the present embodiment, the case where the cylindrical rotating image body 3 and the projection body 4 are used is shown. However, for example, as shown in FIGS. Is also good.

In this embodiment, the rotating image body 3 is rotated by using a motor 8 driven by a battery (not shown) disposed in the base 1, for example. However, it goes without saying that the rotating image body 3 may be configured to rotate by an upward airflow as in the conventional example shown in FIGS.

For example, FIG. 3 shows a rotary image body 3 and a projection body 4 having a cylindrical shape with a lateral mortar, and FIG. 4 shows a rotary image body 3 and a projection body 4 with a side barrel-shaped cylinder. FIG. 5 shows a projection body 4 composed of a planar flower-shaped cylinder and a cylindrical rotating image body 3, and FIG. 6 shows a rotating image body 3 and a projection body 4 having side faces. The projection body 4 has a trapezoidal cylindrical body. In these cases, in addition to the effect produced by decentering the rotation center R of the rotating image body 3 and the center P of the projection body 4, the rotating image body 3 Since the projection body 4 has an irregular shape, it is possible to obtain an even more varied image.

Further, in the embodiment shown in FIG. 7, three rotating image bodies 31, 32, and 33 each having a shape having light sources 21, 22, and 23 inside the projection body 4 are rotated. It is rotatably arranged at a position where the center is eccentric with the center O of the projection body 4.

In the present embodiment, a more varied image can be enjoyed, and each of the rotating image bodies 31, 32,
It is also possible to enjoy the change of the image caused by changing the rotation direction and rotation speed of the light source 33 and the intensity of the light source.

[0022]

As described above, according to the present invention, since the center of rotation of the rotating image body and the center of the projecting object are decentered, the image of the rotating image body projected on the projecting object is not only in the rotating direction but also in the front-back direction. As a result, a variety of images can be obtained.

Further, by decentering the rotation center of the rotating image body and the center of the projection body, the rotating image body on the eccentric side and the projection body can be arranged close to each other. , A very clear image can be projected.

Further, by using a plurality of rotating image bodies, a more varied image can be enjoyed. In addition, the rotating direction and rotating speed of each rotating image body 31, 32, 33, and the intensity of the light source are further improved. It is also possible to enjoy the change of the image caused by changing the image.
