Abstract
An operation body having a pointing function with respect to information includes a chassis having a reflection face, a circuit charging an inner second battery when receiving an electrical power from outside through a terminal exposed from the chassis, and a circuit transmitting switch information to outside cordlessly. On the other hand, an information-input device includes a chassis supporting a keyboard, and an optical system that transmits a light to an operation body operated on the chassis and receives a reflected light of the light. The chassis supporting the keyboard has a recess housing the operation body. The operation portion may be housed in the recess. The second battery is charged when the operation body is housed. And a light emitting of the optical system is stopped when the operation body is housed.
