Abstract

L'objet de la présente invention est de supprimer une diminution du nombre de substrats qui peuvent être stockés dans un bâti qui permet le remplacement de substrats ayant une pluralité de largeurs depuis l'avant du bâti, et d'assurer une liberté de stockage des substrats. La solution selon l'invention porte sur un bâti qui comprend : un premier guide qui comprend une paire de premières rainures permettant l'insertion et le retrait d'un premier substrat depuis l'avant, une paire de deuxièmes rainures dont la position par rapport à la paire de premières rainures est fixe et qui permettent l'insertion et le retrait d'un deuxième substrat depuis l'avant, une première section de fixation/détachement qui peut être attachée/détachée depuis l'avant dans une position prédéterminée par rapport aux premières rainures, et une troisième rainure dont la position par rapport à la première section de fixation/détachement est fixe, et qui, conjointement avec une rainure de la paire de premières rainures, permet l'insertion et le retrait depuis l'avant d'un troisième substrat ayant une largeur plus étroite que celle du premier substrat ; et un second guide qui comprend une seconde section de fixation/détachement qui peut être attachée/détachée depuis l'avant dans une position prédéterminée par rapport au premier guide, et une quatrième rainure dont la position par rapport à la seconde section de fixation/détachement est fixe, et qui, conjointement avec une rainure de la paire de deuxièmes rainures, permet l'insertion et le retrait depuis l'avant d'un quatrième substrat ayant une largeur plus étroite que celle du deuxième substrat.
