d) a module transfer detecting means for detecting a transfer of an operation module (111a-c, 112a-c, 113a-c, 114a-c) from one of the plurality of analyzing devices (110a-c) to another one of the plurality of analyzing devices (110a-c), based on the module identifier associated with the identifier of each system controller (SC1, SC2, SC3) and stored in the information storing means; and e) an information managing means for changing an association of the module identifier of a transferred operation module (111a-c, 112a-c, 113a-c, 114a-c) and the information concerning the use history of the expendable part included in the operation module (111a-c, 112a-c, 113a-c, 114a-c), stored in the information storing means, from a state of being associated with the identifier of the system controller (SC1, SC2, SC3) on a giving end of the transfer, to a state of being associated with the identifier of the system controller (SC1, SC2, SC3) on a receiving end of the transfer, when the transfer of the operation module (111a-c, 112a-c, 113a-c, 114a-c) is detected by the module transfer detecting means. a) a module identifier acquiring means for repeatedly acquiring, from the system controller (115a-c) included in each of the analyzing devices (100a-c), with a previously determined first timing, a module identifier for each of the operation modules (111a-c, 112a-c, 113a-c, 114a-c) connected to the system controller (115a-c), the module identifier being a unique identifier for each of the operation modules (111a-c, 112a-c, 113a-c, 114a-c); b) an expendable part information acquiring means for repeatedly acquiring, from the system controller (115a-c) included in each of the analyzing devices (110a-c), with a previously determined second timing, information concerning a use history of an expendable part included in each of the operation modules (111a-c, 112a-c, 113a-c, 114a-c) connected to the system controller (115a-c); c) an information storing means for storing a module identifier acquired by the module identifier acquiring means, the module identifier being associated with an identifier of the system controller (SC1, SC2, SC3) to which the operation module (111a-c, 112a-c, 113a-c, 114a-c) corresponding to the module identifier is connected, and for storing the information concerning a use history of an expendable part acquired by the expendable part information acquiring means, the information being associated with the identifier of the system controller (SC1, SC2, SC3) to which the operation module (111a-c, 112a-c, 113a-c, 114a-c) including the expendable part is connected; d) a module transfer detecting means for detecting a transfer of an operation module (111a-c, 112a-c, 113a-c, 114a-c) from one of the plurality of analyzing devices (110a-c) to another one of the plurality of analyzing devices (110a-c), based on the module identifier associated with the identifier of each system controller (SC1, SC2, SC3) and stored in the information storing means; and e) an information managing means for changing an association of the module identifier of a transferred operation module (111a-c, 112a-c, 113a-c, 114a-c) and the information concerning the use history of the expendable part included in the operation module (111a-c, 112a-c, 113a-c, 114a-c), stored in the information storing means, from a state of being associated with the identifier of the system controller (SC1, SC2, SC3) on a giving end of the transfer, to a state of being associated with the identifier of the system controller (SC1, SC2, SC3) on a receiving end of the transfer, when the transfer of the operation module (111a-c, 112a-c, 113a-c, 114a-c) is detected by the module transfer detecting means.
