Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 トレイの面を垂直にしても、光ディスクが安 定にトレイに載置でき、かつ載置された光ディスクの中 心穴のトレイに対する位置ずれを少なくする。 【構成】 トレイ1に光ディスク9よりも若干大きい直 径の窪み状のディスク載置部2が形成され、このディス ク載置部2を仕切るディスク案内壁3の上部に、可動突 出部4a,4bと固定突出部5a,5bとが設けられて いる。光ディスク9をディスク載置部2に取り付けると きには、光ディスク9の外周を固定突出部5a,5bと ディスク載置部2の底部との間に差し込み、光ディスク 9の可動突出部4a,4b側を押し込む。これにより、 可動突出部4a,4bは下方に変形し、光ディスク9は ディスク載置部2内に入り込む。少なくとも、ディスク 載置部2の左右側には、ディスク案内壁3が設けられて おり、トレイ1を横向きに垂直にしても、光ディスク9 はディスク載置部2からはみ出さない。 (57) [Abstract] [Purpose] An optical disc can be stably placed on the tray even if the surface of the tray is vertical, and the displacement of the center hole of the placed optical disc with respect to the tray is reduced. [Structure] A tray 1 is formed with a recessed disc mounting portion 2 having a diameter slightly larger than that of an optical disc 9. The movable protrusions 4a and 4b are fixed to the upper portion of a disc guide wall 3 partitioning the disc mounting portion 2. Projections 5a and 5b are provided. When the optical disc 9 is attached to the disc mounting portion 2, the outer circumference of the optical disc 9 is inserted between the fixed protrusions 5a and 5b and the bottom portion of the disc mounting portion 2, and the movable protrusions 4a and 4b side of the optical disc 9 is pushed. This allows The movable protrusions 4 a and 4 b are deformed downward, and the optical disc 9 enters the disc mounting portion 2. At least the disc guide walls 3 are provided on the left and right sides of the disc mounting portion 2, and even if the tray 1 is set sideways and vertically, the optical disc 9 Does not stick out from the disc mounting portion 2.
