PROBLEM TO BE SOLVED: To instantaneously send the operation state of an information processor and peripheral equipment which are connected to an opposite-side optical spatial transmission device by providing a storage part for the optical transmission control part of the optical spatial transmission device and temporarily storing the operation state of the information processor, peripheral equipment, etc., as power management information. SOLUTION: The optical transmission control part of the optical spatial transmission device is provided with the storage part (RAM 18) and the operation state of the information processor, peripheral equipment, etc., is temporarily stored as the power management information. Then the host-side optical spatial transmission device 1 which requests control sends a light signal to the terminal- side optical spatial transmission device 1 which receives the request for control to start the information processor which is connected to the terminal-side optical spatial transmission device 1. Then, an answer signal including the operation state of the terminal-side information processor and the peripheral device connected to the information processor and the connection state of a selecting circuit selecting a power supply destination is sent to the host-side optical spatial transmission device 1. |
