PURPOSE:To perform both loading and pressing of a disk with a single drive source and to simplify the structure of a disk loading device by giving a forward motion to a rack against a spring after loading a mobile chassis by a loading motor to elevate a pressure plate. CONSTITUTION:A disk pressing plate 3 is pivotally supported rotatably by a pivot 4, and a guide pin 9 is engaged to a guide groove 12 of a slidable rack 10. This rack 10 is energized toward a fixed chassis 1 by means of a prescribed spring. While a pinion 31 of a loading motor 29 of a mobile chassis 12 engages with the rack 10. When the motor 29 is driven in such a constitution, the chassis 21 is loaded and the motor 29 is revolved more at the edge of the chassis 1. Therefore the rack 10 moves forward and the pin 9 moves up along the groove 12. While the plate 3 moves down to press a disk D. Thus it is possible to load and press the disk D by a single drive source. |
