Claims

[Scope of Claim for Utility Model Registration] (1) In a microphone that has a switch operation part that protrudes outside the microphone case and can be turned on and off by sliding the operation part, on the extension line in the sliding direction of the said operation part. an engagement hole that extends in the sliding direction and has an opening formed in the microphone case, and a rolling prevention piece that is provided at a position corresponding to the opening in the microphone case and that can move forward and backward from the opening. a rolling prevention part having a retaining part for the opening following the engagement hole, and a rolling prevention part configured to apply a biasing force to the rolling prevention part in a direction in which the rolling prevention piece protrudes from the opening. a spring that is connected to the operating section within the microphone case and extends along the sliding direction toward the anti-rolling section, and has an inclined surface at its tip, and when the operating section is in the on state, the inclined surface; a locking member configured to engage with the engagement hole against the biasing force of the spring so that the inclined surface is released from the engagement hole when the operating section is in an OFF state. microphone. (2) The spring is provided to apply a biasing force to the anti-rolling part in the direction of drawing the anti-rolling piece into the opening, and the locking member is arranged to tilt the locking member when the operating part is in the on state. 2. The microphone according to claim 1, wherein the microphone is configured to engage with the engagement hole against the biasing force of the spring when the surface is released from the engagement hole and the operating section is in an OFF state. (3) In a microphone that has a switch operation part that protrudes outside the microphone case and can be turned on and off by sliding the operation part, an opening that is bored on an extension line in the sliding direction of the operation part and , a rolling prevention part having a rolling prevention piece provided at a position corresponding to the opening in the microphone case and capable of moving forward and backward from the opening, and having a through hole extending in the sliding direction following the rolling prevention piece; A push-up inclined surface is connected to the operating section in the case and extends along the sliding direction toward the anti-rolling section, and is provided at the tip thereof with a push-up inclined surface facing the opening side and parallel to this on the opposite surface. and a push-down inclined surface, and as the operating section is slid from an off state to an on state, a position where the push-down inclined surface contacts the through hole is changed to push down the anti-rolling section and turn on the operating section. an operating section configured to push up the anti-rolling section by changing the position at which the pushing-up inclined surface contacts the through hole as the microphone is slid from the off state to the off state.
