PROBLEM TO BE SOLVED: To solve such the problem that conventional bookstands do not have the function to easily and securely maintain or change spaces for standing books, which causes the spaces to easily shift and the books to fall down when the books are inserted, removed or the like because of a structure of the conventional bookstands which are formed by vertically bending a plurality of plates at a right angle and by raising a part of each plate so that the books are placed in the spaces formed by arranging the raised parts.SOLUTION: Projections are set on bases of space regions of raised parts standing from a flat surface or in the vicinity of the bases so as to easily maintain or change the space of the arranged raised parts for supporting the books. A specification body is formed by forming a connection band in which a part of the flat surface is formed by providing a fitting hole for fitting the projection. The connection band is inserted into the duplicate base of a similar duplicate specification body, so that both the specification bodies are connected by fitting the duplicate projections into the fitting holes. Thereby, it is possible to obtain the bookstand having the function to easily and securely maintain or change the space. |
