Abstract

PURPOSE: To make it possible to transmit the movement of a drive element to a reading element in fidelity and to remoably attach the drive element to a pickup arm carrying the reading element by improving a reproducing element which is equipped with such a drive mechanism as can drive and dislocate the reading element two- dimentionally.
CONSTITUTION: A bracket 33 is fixed to a cartridge base 21, and a second magnetic coupling portion 37 is provided in a manner to correspond to a first magnetic coupling portion 36 of a ferromagnetic material which is fixed to an attachment member 35 bridging the base ends of the legs 16a and 16b of a pickup arm 16. A guide plate 38 made of a non-magnetic material is provided around the coupling portion 37. By the magnetic attractions between the coupling portions 36 and 37, the drive mechanism can be freely attached to and removed from the arm 16. The pressure portions 16al and 16bl are forced into contact with the pivots 9a and 9b of the drive mechanism under a preset pressure so that a reading element 15 of the information signals are brought into contact under a preset pressure
