PROBLEM TO BE SOLVED: To allow for switching of the direction of a luminous flux of the lamp ring of a microphone, with a simple configuration.SOLUTION: In a microphone 11 including a lamp ring 4 and a switchable light guide member 21 into which a luminous flux 100 emitted from a lamp ring enters, the switchable light guide member includes a plurality of light guide parts into which the luminous flux can enter, and can move relative to the lamp ring. The switchable light guide member can change the direction of emission, by selecting a light guide part, into which the luminous flux enters, depending on the position of movement. |
