Patent number: 7627874Abstract: An elastic restriction section (15g), formed in a substantially cylindrical configuration and having the vertical axis is provided to protrude on one side of a rear end section of a chassis (15) formed of a synthetic resin. The chassis constitutes a case body for housing a main body that performs processing of reading or recording of an optical disk. The elastic restriction section (15g) is divided into three elastic members that are elastically deformable into a diameter-reduced state, and provided to protrude at a position substantially diagonally opposite to an engagement position of a movement gear (63) of an open/close drive unit (60), the open/close drive unit (60) advancing/retreating a disk tray (50) carrying the optical disk. In the disk tray (50), an engaging recess (51e) is provided to be engaged with the elastic restriction section (15g) at a home position.Type: GrantFiled: October 13, 2005Date of Patent: December 1, 2009Assignee: Pioneer CorporationInventors: Katsuyuki Kobayashi, Katsuhiro Onodera, Shogo Sato
