Abstract

A disk tray position sensing mechanism which smoothly carries out the action of manually charging a disk tray and a disk apparatus comprising this disk tray position sensing mechanism. The disk apparatus, having a chassis (31), a means for reproducing information recorded on a disk, a disk tray holding the disk and moving between a disk reproducing position and a disk removal position, and a loading drive mechanism (57) for driving the disk tray, is provided, as a disk tray position sensing mechanism (670) provided to sense the position of the disk tray, with a disk tray position sensing switch having a sensing lever, a slider pressing the sensing lever down in a first direction by interlinking with the loading drive mechanism (57), and a projection of a member pressing the sensing lever in a second direction by transmitting the power of the disk tray to the sensing lever.

Description

technical field [0001] The present invention relates to a disk tray position detection mechanism for detecting the position of a disk tray of a disk drive apparatus having the disk tray relative to the apparatus main body. Background technique [0002] Figure 51 It is a bottom view of a disc tray of a conventional disc device. Figure 52 is a plan view of the main body of a conventional disk device, Figure 53 (a) and (b) show the states in which the cam member of the disk tray position detection mechanism provided on the main body of the device is in the first position and the second position, respectively. [0003] Such as Figure 51 As shown, the disk tray 730 of the conventional disk apparatus has a guide groove 731 for the disk tray position detection mechanism. Such as Figure 51 As shown, the guide groove 731 has a first guide groove 732 at the front, a second guide groove 733 at the center, and a third guide groove 734 at the rear. [0004] On the other hand, a d...
