To sort main components built in a game machine without distinguishing a sample machine from a mass-produced machine according to whether the components are reusable.

A processor 42 of an apparatus 40 for managing the game machine obtains a tag ID of a unit 10A in the case of recovering the game machine from a reader 30 and retrieves a storage device 41 with the tag ID as a key to discriminate the class of the game machine 10. The processor 42 refers to a reusability criteria in a unit correspondence table d2 in the storage device 30 with the class as a key. The processor 42 sets the referred reusability criteria as a criteria, and refers to operation history information d9 in the storate device 30 with the tag ID as the key. The processor 42 sorts whether each unit 10A is reusable depending on whether the operation history meets the reusability criteria, and makes an output device of a local server 92 output the result to give information of the result to an operator carrying out recovery operation.
