Holding Or Fastening Of Disk On Rotational Shaft
(AREA)
Abstract
Device for the exploration of phonograph records, in which during the interval between two periods of reproduction the arm of the pickup is guided by a control member and, once a disc has been reproduced, the arm is raised and moved successively without the discs, whereas, once a new disc has been brought to its reproduction position, the pickup arm is moved towards the center e, irrespectively of the diameter of the disc that must be reproduced, it is made to descend on the edge of the disc, given that a member that is rigidly attached to the pickup arm in the horizontal direction is retained with a position corresponding to the diameter of the disc to be reproduced, characterized by the fact that to achieve the movement of the pickup arm towards the center and towards the exterior only a single follower cooperates with the control member, with not only a clutch being provided between the follower and the pickup arm this is also an elastic connection capable of forcing the follower to occupy a predetermined position with respect to the arm of the pickup.
