PROBLEM TO BE SOLVED: To reduce the number of components by using an energizing mechanism for raising a top plate also as an unlocking drive mechanism which unlocks a locking mechanism for locking the top plate horizontally in common, in each flap table whose top plate can be automatically raised when housing a large number of flap tables in a used state where the top plates are horizontal, after using. SOLUTION: The flap table including the top plate, where the top plate can rise and fall to be displaced into a horizontal attitude or an raised attitude, includes the energizing mechanism for energizing the top plate in an raised direction; the locking mechanism for locking the top plate in the horizontal attitude; and the unlocking drive mechanism for unlocking the locking mechanism. The energizing mechanism is used also as the unlocking drive mechanism. COPYRIGHT: (C)2008,JPO&INPIT
