To provide a camera capable of performing radio communication with other unit by jointly using a conductive component previously provided for the camera as a radio antenna without using an independent radio antenna. Because a conductive component (e.g. a reflector of flash) previously provided for an electronic camera and insulated from a camera housing but not electromagnetically shielded is jointly used as a radio antenna, the electronic camera can perform radio communication with other unit without using an independent antenna.

What is claimed is: 1. A camera, comprising: a camera housing; a communication device, accommodated inside the camera housing, which allows radio communication with another unit; and a non-communicating purpose component attached to the camera housing, said non-communicating purpose component being
What is claimed is: 1. A camera, comprising: a camera housing; a communication device, accommodated inside the camera housing, which allows radio communication with another unit; and a non-communicating purpose component attached to the camera housing, said non-communicating purpose component being a conductive component insulated from the camera housing but not shielded electromagnetically, the non-communicating purpose component also serving as a radio antenna, operatively connected with said communication device and outputting and/or receiving radio waves to/from said another unit, and the non-communicating purpose component being disposed where the non-communication purpose component is not unconsciously touched by a user during a picture taking operation, wherein the non-communicating purpose component includes a lens tube for supporting a lens therein. 2. A camera, comprising: a camera housing; a communication device, accommodated inside the camera housing, which allows radio communication with another unit; and a non-communicating purpose component attached to the camera housing, said non-communicating purpose component being a conductive component insulated from the camera housing but not shielded electromagnetically, the non-communicating purpose component also serving as a radio antenna, operatively connected with said communication device and outputting and/or receiving radio waves to/from said another unit, and the non-communicating purpose component being disposed where the non-communication purpose component is not unconsciously touched by a user during a picture taking operation, wherein the non-communicating purpose component includes a hot shoe to which an accessory is set, the hot shoe being attached to the camera housing through an insulating spacer and an insulating washer by a hot-shoe fixing screw. 3. The camera according to claim 1, wherein said communication device includes a high frequency module connected to said non-communicating purpose component by a high frequency cable. 4. A camera, comprising: a camera housing; a communication device, accommodated inside the camera housing, which allows radio communication with another unit; and a non-communicating purpose component attached to the camera housing, said non-communicating purpose component being a conductive component insulated from the camera housing but not shielded electromagnetically, the non-communicating purpose component also serving as a radio antenna, operatively connected with said communication device and outputting and/or receiving radio waves to/from said another unit, and the non-communicating purpose component being disposed where the non-communication purpose component is not unconsciously touched by a user during a picture taking operation, wherein the non-communicating purpose component includes a reflector of a flash, the reflector being provided inside an opening formed in the camera housing. 5. A camera, comprising: a camera housing; a communication device, accommodated inside the camera housing, which allows radio communication with another unit; and a non-communicating purpose component attached to the camera housing, said non-communicating purpose component being a conductive component insulated from the camera housing but not shielded electromagnetically, the non-communicating purpose component also serving as a radio antenna, operatively connected with said communication device and outputting and/or receiving radio waves to/from said another unit, and the non-communicating purpose component being disposed where the non-communication purpose component is not unconsciously touched by a user during a picture taking operation, wherein the non-communicating purpose component includes a ring member provided inside a lens tube and surrounding a lens. 6. A camera, comprising: at least one member selected from a group consisting of a hot shoe to which an accessory is set, a reflector of a flash, a lens tube for supporting the lens therein, a ring member that supports the lens with respect to the lens tube, and a cover for a battery compartment provided at a bottom of the camera; a communication device which allows radio communication with another unit, wherein one of said at least one member is connected to said communication device as a radio antenna for outputting and/or receiving radio waves to/from said another unit, said at least one member is formed by a conductive component insulated from a camera housing, but not electromagnetically shielded, wherein, each member of the group being disposed where said each member is not unconsciously touched by a user during a picture taking operation. 7. The camera according to claim 6, wherein said at least one member is the lens tube. 8. A camera, comprising: at least one member selected from a group consisting of a hot shoe to which an accessory is set, a reflector of a flash, a lens tube for supporting the lens therein, a ring member that supports the lens with respect to the lens tube, and a cover for a battery compartment provided at a bottom of the camera; a communication device which allows radio communication with another unit, wherein one of said at least one member is connected to said communication device as a radio antenna for outputting and/or receiving radio waves to/from said another unit, said at least one member is formed by a conductive component insulated from a camera housing, but not electromagnetically shielded, wherein, each member of the group being disposed where said each member is not unconsciously touched by a user during a picture taking operation, and wherein said at least one member is the hot shoe. 9. A camera, comprising: at least one member selected from a group consisting of a hot shoe to which an accessory is set, a reflector of a flash, a lens tube for supporting the lens therein, a ring member that supports the lens with respect to the lens tube, and a cover for a battery compartment provided at a bottom of the camera; a communication device which allows radio communication with another unit, wherein one of said at least one member is connected to said communication device as a radio antenna for outputting and/or receiving radio waves to/from said another unit, said at least one member is formed by a conductive component insulated from a camera housing, but not electromagnetically shielded, wherein, each member of the group being disposed where said each member is not unconsciously touched by a user during a picture taking operation, and wherein said at least one member is the reflector. 10. A camera, comprising: at least one member selected from a group consisting of a hot shoe to which an accessory is set, a reflector of a flash, a lens tube for supporting the lens therein, a ring member that supports the lens with respect to the lens tube, and a cover for a battery compartment provided at a bottom of the camera; a communication device which allows radio communication with another unit, wherein one of said at least one member is connected to said communication device as a radio antenna for outputting and/or receiving radio waves to/from said another unit, said at least one member is formed by a conductive component insulated from a camera housing, but not electromagnetically shielded, wherein, each member of the group being disposed where said each member is not unconsciously touched by a user during a picture taking operation, and wherein said at least one member is the ring member.
