[0002]

2. Description of the Related Art Conventionally, to train an infant's imagination and creativity, there is a method in which an infant is made to combine blocks of different shapes to form a shape similar to an existing thing. However, since such blocks do not have any means for connection, if they are touched with a little effort, they fall down and separate quickly, so that the preservability of the finished blocks is poor. For this reason, blocks of the same shape that are formed in a predetermined shape and can be connected to each other by a combination of a projection and a concave portion have been proposed.

[0003]

However, in such blocks having the same shape, since the shape is the same, the shape of the one made always has a great difference from the real one, so that the recreational property and the recognition of the thing for the infant can be obtained. Educational effect is low.

[0004] In the development stage of infant recognition of objects, two-dimensional letters and numbers are completely recognized before three-dimensional object shapes. Even so, almost nothing can be made.
Rather, it is easier to recognize two-dimensional letters and numbers first. However, such a block exclusively for letters and numbers has not yet been proposed in the world.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a building block having connection means and capable of producing a shape similar to a correct character.
