Abstract: A wireless microphone is provided. The wireless microphone includes: a transmitter wirelessly transmitting audio signals converted from sound collected with a microphone unit; and a receiver receiving said audio signals. A clip is provided on one surface of the transmitter in which the microphone unit is attached to the other surface thereof; and the transmitter is capable of being mounted on a plane using the clip.

Abstract: An accessory includes an apparatus-side portion and an accessory-side portion to be attached to the apparatus-side portion. The accessory-side portion includes a surface, an internally threaded portion open on the surface, and an externally threaded member to be rotatably engaged with the internally threaded portion. The externally threaded member is positioned either in a retraction position by rotation of the externally threaded member in one direction or in an extension position by rotation of the externally threaded member in an opposite direction.

Abstract: Disclosed is an accessory detachably mounted on an electronic device. The accessory includes a case, an electronic circuit housed in the case and activating the accessory, and an accessory's-side connector for supplying power to the electronic circuit or sending and receiving signals. The accessory's-side connector includes a portion of the case in which a plurality of leads is provided and a plurality of contact strips constructed such that a portion of the plurality of leads is exposed to the portion of the case.

Abstract: An accessory an accessory includes an apparatus-side detachably attaching portion including an accessory-side apparatus detachably attaching portion to be attached to the apparatus-side detachably attaching portion, the accessory-side apparatus detachably attaching portion including an attachment/detachment surface, an internally threaded portion open on the attachment/detachment surface, and an externally threaded member to be rotatably engaged with the internally threaded portion. The externally threaded member is positioned either in a retraction position by rotation of the externally threaded member in one direction or in an extension position by rotation of the externally threaded member in an other direction opposite to the one direction. The retraction position is a position in which a lead end portion of the externally threaded portion of the externally threaded member is retracted into the internally threaded portion and the externally threaded portion is exposed on the attachment/detachment surface.

Abstract: A conversion lens apparatus includes a first and second barrels for housing a first and second lenses, wherein a back portion of the first barrel is detachably attached to the main body side barrel, a back portion of the second barrel is detachably attached to a front portion of the first barrel, the first barrel is configured, so a magnification rate of total optical system including the first lens and imaging optical system is converted to be more wide-angle side than magnification rate of the imaging optical system itself, when attached to the main body side barrel, and the second barrel is configured, so the magnification rate of total optical system including the first lens and imaging optical system is converted to be more telescopic side than magnification rate of the imaging optical system itself, when attached to the first barrel which is attached to the main body side barrel.

Abstract: A cassette tape recorder having a printed circuit board on which electronic parts forming an electronic circuit of a tape recorder are mounted, in which the board is used as a chassis. A tape cassette can be loaded onto this printed circuit board so that the whole of the cassette tape recorder can be reduced in thickness. In the event the printed circuit board is warped, the perpendicularity of a capstan relative to a cassette tape can be maintained so as to maintain stable running of the cassette tape even though the printed circuit board is warped.
