A non-contact ranging type old record recording device

Abstract

The invention discloses a non-contact distance measurement type old record recording device which comprises a rotating platform, an electric lead screw guide rail, a distance measurement sensor, a signal processing circuit and a comprehensive processing module. The rotating platform comprises a stepping motor and a horizontal plate, the horizontal plate is used for supporting and placing a to-be-recorded record, and the central axis of the placed record is coaxial with the central axis of the horizontal plate; a distance measuring sensor is mounted on a sliding block of the electric lead screwguide rail, the signal processing device converts a signal of the distance measuring sensor into a digital signal and transmits the digital signal to the comprehensive processing module; during work,the comprehensive processing module controls the rotating platform to rotate at a constant speed, records the current rotating position, controls the electric lead screw guide rail to move the sliding block to the initial position, starts the distance measuring sensor to start to collect the distance information, and after the rotating platform rotates one circle, the electric lead screw guide rail moves to the position of one disc groove to start to collect information at the next position, so that the problem that an existing record cannot be directly played and needs to be rerecorded is solved.
