Abstract
One end of an arm main body is formed integral with a head shell for mounting a cartridge while the other end thereof supports a balance weight. A mounting portion is formed integral with the arm main body between the ends thereof and close to the other end thereof. The mounting portion of the arm main body may be detachably mounted on an inner gimbal which in turn is mounted with pivot bearings to an outer gimbal for rotation about a horizontal axis so as to permit the arm main body to nod up and down. The outer gimbal in turn is mounted with pivot bearings to a yoke for rotation about a vertical axis so as to permit the arm main body to rotate in a horizontal plane. The yoke in turn is securely attached to the base of the pickup arm device.
