<p><P>PROBLEM TO BE SOLVED: To control the power supply of one apparatus by another apparatus in an electronic apparatus having separable housings. <P>SOLUTION: A control unit 1a1 causes a path switching unit 1a2 to perform switching to electrically connect a contact part 1a5 and a detection unit 1a3 when the power supply of a housing 1a is off, and causes the path switching unit 1a2 to perform switching not to electrically connect the contact part 1a5 and the detection unit 1a3 when the power supply of the housing 1a is on. The path switching unit 1a2 is capable of performing switching such that the contact part 1a5 and the detection unit 1a3 are electrically connected or not electrically connected. The detection unit 1a3 detects a notification signal notifying the state of the power supply of the housing 1b, that is received from the control unit 1a1 via a contact part 1b5 and the contact part 1a5. A power supply unit 1a4 controls the power supply of the housing 1a when a second notification signal is detected by the detection unit 1a3. The contact part 1b5 can be electrically connected with the contact part 1a5. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
