Abstract
The apparatus comprises: a base portion (); inwardly extending radial arms () resiliently cantilevered from the base portion (); disk-engaging means () at the inner ends of the arms () for releasably engaging the central hole of a disk () and supporting the center of the disk () away from the base portion (). Each arm () has first pivot means () in the region where the arm () joins the base portion () and second pivot means () radially inward thereof. Depression of the disk-engaging means () towards the base portion () causes the inner ends of the arms () and the center of the disk (), to be depressed towards the base portion (), the arms () initially pivoting about the first pivot means () and subsequently pivoting about the second pivot means () until retention of the disk () by the disk-engaging means () is released. This enables the thickness of the apparatus to be reduced, e.g. to 4 mm or less. Due to the presence of the second pivot means (), the periphery of the base portion () also tends to rise when the disk-engaging means () is depressed to help in ejecting the disk ().
