PROBLEM TO BE SOLVED: To detect whether a lid body is attached to a main body part or not in a simple configuration.SOLUTION: A terminal (100) comprises: a main body part including a communication part and a control part; a lid body detachably attached to the main body part and including an antenna part; an antenna-part-side terminal on the side of the antenna part; and a main-body-part-side terminal which is a terminal on the side of the main body part and connected to the antenna-part-side terminal when the lid body is attached to the main body part. The control part includes a port (P) which receives a voltage of an output line of a predetermined voltage source, and a determination part configured to determine whether the lid body is attached to the main body part or not on the basis of a potential received via the port. The output line passes through a connection part between the antenna-part-side terminal and the main-body-part-side terminal when the lid body is attached to the main body part, and is interrupted when the lid body is not attached to the main body part. |
