PURPOSE: To use article storing space effectively by providing article storing places disposed in a matrix and article loading tables capable of moving in a matrix, which are mounted on the article storing places.

CONSTITUTION: Article storing places A11WA66 are disposed in a matrix of six rows and six columns, and article loading tables B11WB55 are respectively mounted corresponding to the article storing places A11WA56. In case of taking out the article loading table B22 mounted on the article storing place A22, the article loading tables B32WB35, B42WB45, B52WB55 positioned in the third, fourth and fifth rows are respectively moved along the row, to the right for one article storing place. Subsequently, the article loading table B22 is moved along the column downward to the article storing place A62, and the article loading table B22 is moved along the row to right to the article storing place A66. Thus, the article loading table B22 is taken out from the article storing place A66.
