Control device automatically controlling phonograph to shutdown

Abstract

The invention discloses a control device automatically controlling a phonograph to shutdown; the control device comprises the following units: a rotary shaft vertically penetrating a phonograph palletpedestal; a singing rod assembly connected with the top of the rotary shaft; a light shade connected with the bottom of the rotary shaft; an optical coupler switch assembly arranged on the pallet pedestal; the light shade is in a triangle shape or sector shape. The optical coupler groove can detect the light shade linked with the singing rod; when the music of a disc is finished, the equipment can be intelligently stopped, thus stopping the disc from rotations, ensuring the disc and the phonograph not to be damaged, and preventing equipment damages under conditions in which the phonograph cannot be automatically stopped.

Description
