Patent ID: 7899920

Claim:
A network apparatus capable of being connected with a network and capable of connecting to one or more peripheral devices, and which controls access from terminals on the network to a connected peripheral device, the network apparatus comprising: a communicator that receives a reservation command and a sender identifier (sender ID) from one of the terminals on the network, wherein the reservation command requires the network apparatus to reserve an access right for a peripheral device that is not yet connected, and the sender ID identifies a sender of the reservation command; a detector that detects a peripheral device newly connected to the network apparatus and acquires a peripheral device identifier (peripheral device ID) from the detected peripheral device; and an access controller that rejects access to the detected peripheral device from senders other than the sender identified by the received sender ID in a case where the detector detects the newly connected peripheral device; wherein: the communicator is configured to receive a first reservation command that accompanies the peripheral device ID and a second reservation command that does not accompany the peripheral device ID; the access controller rejects access to the detected peripheral device from senders other than the sender identified by the received sender ID that is received along with the first reservation command in a case where the detected peripheral device has the same peripheral device ID as the received peripheral device ID accompanied by the first reservation command; and the access controller rejects access to the detected peripheral device from the senders other than the sender identified by the received sender ID that is received along with the second reservation command in a case where the detected peripheral device does not have the same peripheral device ID as the received peripheral device ID accompanied by the first reservation command.
