Description

[Detailed description of the invention] <Technical field> The present invention relates to a constellation learning device.

<Prior Art> Conventionally, the most common method for observing and learning constellations is to take a constellation map outdoors and compare it with the actual stars in the sky. However, since conventional constellation maps represent the entire sky within a single oval or circle, it requires skill to compare the actual stars in the sky with the constellation map, making it quite difficult for elementary school students to learn. . In addition, since learning must be done outdoors, learning cannot be done on cloudy or rainy days, and students' motivation to learn decreases when the temperature is low, such as in the winter.

<Object of the Invention> The object of the present invention is to enable the user to observe stars while staying indoors with the same sense of reality as looking up at the actual stars in the sky, and to instantly switch to use the same device for a constellation map. [Structure of the Invention] To achieve this object, the constellation learning device of the present invention has pinholes arranged corresponding to the stars in the sky, and constellation names and constellation names on the surface. A constellation panel on which constellation lines are displayed, a dark box in which the constellation panel is removably attached to a window on one side and an eyepiece for observing the constellation panel, and the surface of the constellation panel is illuminated. It is characterized by having a lamp that blinks and an operation switch that causes the lamp to blink.

<Function> If you look into the dark box from the eyepiece with a constellation panel attached to the window of the dark box, when the lamp is off, the external light that passes through the pinhole and enters will be observed as if it were starlight, and the lamp When the light is on, the constellation names and lines displayed on the surface of the constellation panel can be visually recognized by superimposing the external light that passes through the pinhole and enters the constellation panel.

<Example> FIG. 1 shows a perspective view of an external appearance of an example of the present invention, FIG. 2 shows a sectional view thereof, and FIG. 3 shows a surface view of an example of a constellation panel.

A window 2 is opened on one side of a rectangular parallelepiped dark box 1, and a constellation panel 3 is attached to cover the window. An eyepiece hole 4 is provided at the center of the wall surface of the dark box 1 facing the window 2, so that the constellation panel 3 can be observed. A lamp 5 that illuminates the surface of the constellation panel 3 is installed inside the dark box 1, and a lamp 5 is installed outside the dark box.
A battery 6 and a flashing switch 7 are provided for lighting the lamp.

In the constellation panel 3, pinholes 8 of sizes corresponding to the stars of the constellation are bored at the positions of the stars of the constellation, and constellation names 9, constellation lines 10, etc. are displayed on the surface. A plurality of constellation panels 3 are manufactured according to the time and direction, and can be selectively used.

When using this device, first point the dark box 1 toward a bright source such as sunlight or an indoor lamp and observe it through the eyepiece hole 4.The transmitted light from the pinhole 8 will appear as if it were starlight. It gives you the feeling of observing the stars in the night sky. After sufficiently observing the stars in this state, by turning on the switch 7 and lighting the lamp 5, the constellation name 9 and the constellation line 10 displayed on the surface of the constellation panel 3 are illuminated. By repeatedly turning the switch 7 on and off, the child learns to associate constellations with the stars visible in the night sky.

As a modified embodiment of the present invention, a side observation hole may be provided on the side surface of the dark box 1 so that the instructor can provide explanations while looking through the side observation hole. Additionally, a fluorescent or light-emitting diode light-emitting arrow is attached to the end of the pole that can be operated by the instructor.
It can also be structured so that you can point out any star and explain it.

FIG. 4 shows a sectional view of another embodiment of the invention.
In this embodiment, an eyepiece lens 11 is provided in the eyepiece section,
A feature is that a reduced size constellation panel 3 can be detachably attached to the opening at the tip of the cylindrical body 12 which serves as a dark box. According to this embodiment, it is possible to obtain a realistic feeling of the actual night sky while downsizing the entire apparatus.

<Effects of the Invention> According to the present invention, since it is not an image type like a planetarium or a projector but a translucent type, it is visually perceived in the same way as actual starlight, giving an excellent sense of realism.
Furthermore, since the same star image can be shared and explanatory diagrams such as constellation names and constellation lines can be added or deleted, the learning effect is high. Moreover, it has a simple structure and can be manufactured at an extremely low cost, making it ideal for use as a craft teaching material for children, an appendix for educational magazines, and the like.
