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: An apparatus to indicate a state where a communication device connected to a communication wire and a power line is protected from a surge current. A toroidal coil picks up a rapid increase of current caused by a rapid increase of voltage that occurs in the communication wire and/or the power line. The toroidal coil is connected to the current detecting unit. The current detecting unit converts the current from the toroidal coil into a voltage and supplies it to a switching circuit. The switching circuit turns on an indicator light circuit to light up an LED of the indicator light circuit.
