A shelving system including a plurality of movable shelves ( 1 ) installed for back-and-forth movement on a travel path through a travel support device, thereby to handle articles with respect to the movable shelves ( 1 ) opposed to a working aisle (S) by using the working aisle (S) opened between the movable shelves ( 1 ). Each movable shelf ( 1 ) includes a pair of movement detectors ( 19 ) disposed in a left-right direction (B) perpendicular to the travel direction (A) of the movable shelves ( 1 ). Absolute coordinates of each movement detector ( 19 ) are found based on detection signals from the pair of movement detectors ( 19 ) of each movable shelve ( 1 ). The amount of left-right directional deviation from the travel path (i) of the movable shelves ( 1 ) is corrected based on the amount of deviation of the absolute coordinates in the left-right direction (B). Further, the attitude of the movable shelves ( 1 ) is corrected to be perpendicular to the travel direction (A) based on positional deviation of the absolute coordinates in the travel direction (A), i.e. traveled distance deviation.
