Abstract

PURPOSE: To make the transmittion of information accurate and to facilitate the coupling and separation of a pickup and a drive mechanism by connecting the pickup arm and a drive mechanism in a knife-edge method through a contact pressure applying member a pressure bias member.
CONSTITUTION: The legs 6a and 6b of a pickup arm 6, which is equipped with a reading element 7, have their leading ends 6a1 and 6b1 supported in a knife-edge method upon the pivots 20a and 20b of the moving portion A of a drive mechanism so that the necessary pressure of the element 7 upon a recording medium such as a disc is established by a pressure bias member 22 which is connected to a contact pressure applying member 21 made of an elastic material such as rubber. With this construction, the members 14 and 22 become independent of the two-dimentional tracking vibrations from the moving portion A to the element 7 so that the vibrations are transmitted to the element 7 and so that the connection and separtin between the arm 6 and the drive mechanism can be facilitated
