An optical disc player comprises a read objective on a carriage which is translated to and fro with the aid of a drive unit with an electric motor by cooperation of a drive pinion and a gear rack, so that the read objective travels between a minimum diameter and a maximum diameter of the disc to be read, between which the information is contained. A pinion and a gear wheel of the drive unit cooperate with each other without play, in that the pinion is mounted on a pivoting member which is resiliently loaded, so that the pinion and the gear wheel are in resilient engagement with each other. During work on the optical disc player the pivoting member can be pivoted away by hand, so that the teeth of the pinion and the gear wheel are disengaged from each other so that a quick, practically unhampered translational movement of the carriage is possible. |
