Abstract
A radio input device includes a holding part to be held by an operator; an operation part to be operated by the operator; a transmission part transmitting radio waves from an antenna according to the operation of the operation part; and a blocking part avoiding influence of a surrounding electric conductor on the radio waves.
Claims19
A wireless mouse comprising:
- a holding part to be held by an operator;
- an operation part to be operated by the operator;
- a transmission part transmitting radio waves from an antenna according to the operation of the operation part;
- and
- a blocking part that is separate from the holding part and is provided as a thin conductive film on the inner surface of the holding part, the blocking part being configured to reduce the influence of an electric conductor, which directly contacts the holding part, on the radio waves.
2 more elements
A wireless mouse, comprising:
- an antenna producing a mouse signal;
- and
- a resin structure mouse housing surrounding said antenna, the housing having a thin conductive film formed along an inner surface thereof at a portion of the housing where a hand of a user contacts the wireless mouse.
A wireless mouse, comprising:
- a housing having shielding formed along an inner surface of the housing at a portion of the housing where a hand of a user contacts the wireless mouse, and the shielding having an opening at a portion of the housing where a hand of a user does not contact the wireless mouse;
- and
- an antenna inside the housing producing radio waves that are transmitted through the opening in the shielding.
