A frame receiving member 22 having portions 25 and 26 fitted into one end opening of the lens barrel 20, and a peripherally hinged portion of the frame receiving member 22 rotatably supported by the hinge portions 25 and 26. A pair of left and right lens frames 27 and 28 that are alternately inverted and fitted in the lens 22, a magnifying lens 29 for eyepiece observation that is fitted and held in the one lens frame 27, and a other lens frame 28 that are fitted and held. And a magnifying lens 30 for projection.

[0006]

According to the kaleidoscope having the above-described structure, the one lens frame 27 in which the magnifying lens 29 for eyepiece observation is fitted is reversely fitted in the frame receiving member 22 and the lamp 12 is turned on. Observed objects 1 such as colored paper pieces housed in 15
8 is illuminated with lamp light from the back side, and the image of the observation object 18 appears as a beautiful diffuse reflection image on the reflecting mirror surface 21 on the inner surface of the lens barrel. can do.

Further, the main body 1 is installed horizontally as shown in FIG. 3, and the magnifying lens 3 for projection is provided in this horizontally installed state.
The other lens frame 28 in which 0 is fitted is attached to the frame receiver 22.
If the lamp 12 is turned on and the lamp 12 is turned on, a beautiful diffuse reflection image reflected on the reflecting mirror surface 21 on the inner surface of the lens barrel can be projected on the projection screen S for enlarged observation.

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 base 3 having a horizontal installation surface 2.
In addition, the main body 1 is a synthetic resin main body which is provided with a lens barrel holder 4 and a lamp box 5 which are opposed to and spaced apart from the horizontal placement surface 2 and which can be installed horizontally and vertically. A pair of lens-barrel guide projections 6 and 7 projecting at the front and rear positions of the lamp box 5 and a container positioning recess 8 having a circular cross section that is recessed at the front position of the lamp box 5. The closed end surface portion 5a of the lamp box 5 and the box side end surface portion 3a of the base 3 form a main body upright support portion 9. The lens barrel holder 4 is provided with a lens barrel guide protrusion 4a and a V-shaped notch 4b for guiding the lens barrel as shown in FIG. Reference numeral 10 is a translucent cover of opalescent synthetic resin that closes the holder-side opening of the lamp box 5, and the translucent cover 10 forms a lamp projecting portion 11.

Reference numeral 12 denotes a projection lamp which is held in the box 5 as shown in FIG. 2 and which illuminates the translucent cover 10 from the inside of the box. The projection lamp 12 is a battery 13 housed in the switch 13 and the main body base 3. Electrically connected to
The switch 13 is turned on when the switch 13 is closed.

Reference numeral 15 denotes a flat transparent container which is set at a front side position of the lamp projecting portion 11 (portion of the container positioning recess 8) so as to be manually rotatable, and is attached to and detached from the circular container body 16. It is composed of a lid 17 capable of being opened, and an observation object 18 such as a piece of colored paper is stored inside.

Reference numeral 20 denotes a lens barrel holder 4 and lens barrel guide projections 6 and 7 of the main body 1 which are inserted and held so as to be movable toward and away from the set container 15 and which have a triangular cross section and are open at both ends. In the lens barrel, the inner surface of the triangular lens barrel 20 is formed as a reflecting mirror surface 21. Reference numeral 22 denotes a circular frame-shaped frame receiver fitted into the opening at one end of the lens barrel 20.
Reference numeral 2 is formed of a synthetic resin circular frame having a lens barrel fitting port 23, a communication hole 24 communicating with the inside of the lens barrel 20, and a pair of left and right peripheral side hinge portions 25 and 26.

Reference numerals 27 and 28 denote a pair of left and right lens frames which are rotatably supported by the peripheral side hinge portions 25 and 26 of the frame receiver 22 and which are alternately inverted and fitted in the receiver 22, respectively. A magnifying lens 29 (convex lens) for eyepiece observation is fitted and held in the lens frame 27, and a magnifying lens 30 for projection, which is a convex lens having a magnifying power larger than that of the lens 29, is fitted and held in the other lens frame 28. Has been done.

Then, the main body 1 is installed vertically as shown in FIG. 2, and in this vertically installed state, the one lens frame 27 in which the magnifying lens 29 for eyepiece observation is fitted is attached to the frame receiver 22. When the lamp 12 is turned on by closing the switch 13 as shown in FIG.
An observation object 18 such as a colored paper piece accommodated in the inside is illuminated with a lamp light from the back side, and an image of the observation object 18 is reflected on the reflection mirror surface 21 inside the lens barrel 20 as a beautiful diffuse reflection image. A magnifying observation can be performed by looking through the magnifying lens 29 for observation.

Further, the main body 1 is installed horizontally as shown in FIG. 3, and the magnifying lens 3 for projection is provided in this horizontally installed state.
The other lens frame 28 in which 0 is fitted is attached to the frame receiver 22.
If the lamp 12 is turned on by turning the switch 13 on and off as shown in FIG. 3, a beautiful diffuse reflection image reflected on the reflection mirror surface 21 inside the lens barrel 20 is projected on the projection screen S and enlarged. You can also observe.

[0016]

Since the kaleidoscope of the present invention is as described above, the observation object 18 such as a piece of colored paper is attached to the lens barrel 29 of the lens barrel.
The observation 1
The specular reflection image of 8 (a beautiful diffuse reflection image reflected on the reflection mirror surface 21 on the inner surface of the lens barrel) can be projected on the projection screen S and observed in a magnified manner, providing a kaleidoscope that is more interesting than before. It has an excellent practical effect.
