Description

[Detailed description of the invention] This invention relates to a reflective block or mirror cube that can make various images appear by utilizing the reflection of light. By enjoying various images, students can understand the linearity of light rays and the properties of reflective mirrors.

The present product will be explained below with reference to the drawings. Reference numeral 10 is a block in the form of a regular cubic box, and reference numerals 1 and 2 are open faces from which two adjacent faces have been removed, which together form an opening 7.

Reference numeral 8 denotes a plane reflecting mirror (mirror) arranged and fixed on a common diagonal surface with respect to the aperture, and is
2 has two optical paths 7a,
7b is formed. Numerals 5 and 6 are block surfaces that form the back surface of the mirror, and 3 and 4 are block surfaces that form the side surfaces of the mirror.

The proposed block itself has the above-mentioned structure, but by preparing a plurality of these blocks, changing the orientation of the respective two opening surfaces 1 and 2, and combining and connecting them, various images can be viewed. It is.

When connected as shown in FIG. 2, the image light beam entering from the aperture surface 1, that is, the optical path 7a, is reflected by the two mirrors 8, and the viewer sees an inverted image.

Further, a yellow circular mark is pasted on the outer surface 4 of each block, and when the four blocks are arranged as shown in FIG. 3 and observed from above, a yellow circle is reflected on each mirror 8.

Furthermore, if the blocks are arranged in the relationship shown in FIG. 4 and observed, an erect image can be seen.

As described above, with this product, a specific aperture of one block can be connected to the apertures of other blocks in three directions, so that a variety of images can be enjoyed by alternately combining these.

Each surface of the block is colored red for 3, yellow for 4,
By commonly specifying colors such as blue for 5 and green for 6, it is possible to easily determine the stationary state of the adjacent blocks facing the mirror 8, and also to determine the positional state of the surface of the mirror 8 of each block from the outside. In addition, when playing with combinations such as those shown in FIG. 4, the combinations can be easily achieved.

[Brief explanation of the drawing]

Figure 1 is a perspective view of the proposed reflective block alone, Figure 2
The figure is a perspective view of a two-tiered combination, FIG. 3 is a perspective view of an arrangement example that creates a reflective pattern on the side surface of the blocks, and FIG. 4 is a perspective view of another mode of connection. 1, 2... are aperture surfaces, and 8 is a mirror.

Claims (1)

[Claims for Utility Model Registration] (1) A two-sided opening block formed by removing two adjacent sides of a regular cubic box, and a flat reflecting mirror 8 provided on a diagonal surface common to the opening. A reflective block. (2) The reflective block according to claim 1 of the utility model registration claim, wherein a colored display mark is attached to each surface of the two-sided open block.
