Autochanging device of video disk

Abstract

Abstract PURPOSE: To avoid the damage of the disk when it is carried in and out, by installing the carrier means which is moved up and down in accordance with the carrying- in/out timing of the disk and in opposition to the notch on the fringe of the fixed table incorporating a turntable. CONSTITUTION: A notch is provided on the fringe of the fixed table 80 incorporating a turntable in opposition to the notch so that the tip of the support frame 153 of the carrier means 10 can be moved up and down by the excitation of the solenoid 164. When the disk is carried in, the desired shelf plate 28 is pushed out midway. And thus the lower face of the disk is made to touch the roller 154 of the frame 153 via the notch of the plate 28. Then a negative pressure suction is given to the disk via the suction pipes 158 and 159, and at the same time the tip of the frame 153 is lifted up higher than the fringe of the table 80. And also the motor 170 gives rotations to the rollers 154 and 155. If the negative pressure suction is interrupted, the disk is carried onto the table 80 by inertia. And when the disk is carried out, the same action is carried out with the frame 153 being held at a high position. COPYRIGHT: (C)1981,JPO&Japio
