Abstract: A coating apparatus for coating a sensitizing solution onto a surface of an elongated metal plate includes a transfer roller and a coating nozzle for coating the sensitizing solution on a circumferential surface of the roller. The circumferential surface of the transfer roller is in contact with the surface of the metal plate running in the longitudinal direction under a predetermined tension. The transfer roller is rotated in a direction opposite to that in which the metal plate is run, so that the coated sensitizing solution is transferred from the circumferential surface of the transfer roller on the surface of the metal plate.

Abstract: A turntable apparatus bears and rotates a disc inserted into a reproducing apparatus for signals recorded on the disc through a casing inlet opening. The turntable apparatus comprises a turntable rotatably supported on a chassis to move vertically and a center spindle rotatably supported coaxially with an axis of rotation of the turntable and received in a recess at the center portion of the turntable to move vertically. When the turntable is in its nonreproducing position, it is located below the casing inlet opening, and the center spindle is wholly contained in the recess. When the turntable is in its reproducing position, it is located above the casing inlet opening to bear the disc thereon, and the center spindle projects above the top surface of the turntable.
