A buckle switch (16) and a microcontroller (18) are provided. A power supply V is connected to the buckle switch (16), which switches the connection with the power supply V between a connected state and a disconnected state. The microcontroller (18) is connected with the buckle switch (16) and includes a removal switch input port (22) and a removal control port (20). The removal switch input port (22) detects the state of the buckle switch (16). The removal control port (20) is connected to the buckle switch (16) via a pull-down resistance (R1) and controls whether the pull-down resistance (R1) operates. The microcontroller (18) controls the removal control port such that the pull-down resistance (R1) does not operate when the buckle switch (16) is in the connected state and such that the pull-down resistance (R1) does operate when the buckle switch (16) is in the disconnected state.
