Patent number: 6657940Abstract: The space required for an apparatus with a motor-driven lid, such as a CD player, is minimized. The lid is guided by an internal gear under the lid, and a follower wheel under the lid. The wheel rides in a guide groove at the rear of the apparatus housing. A drive motor rotates a pinion which engages a short rack and moves the lid straight rearwards while the follower wheel rides in a horizontal groove portion. The rack merges into an internal gear, so that continued pinion rotation raises that part of the lid while moving it rearward. At the same time, the follower wheel rides along a downwardly extending curved groove portion, so that the rear edge of the lid moves to a lower position while the front of the lid moves up and rearward, exposing an opening in the housing for access to the interior.Type: GrantFiled: August 25, 1998Date of Patent: December 2, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Kunio Takeda, Hirotoshi Yokono

Patent number: 6643241Abstract: In an optical disk reproducing apparatus 1 in which a mounting tray slides to a projected position and a contained position with respect to the apparatus main body, to slide the mounting tray at a series of continuous predetermined speeds independent of change in environmental conditions. A series of continuous application voltages, to be supplied from a drive source 8 to an output motor 16 so as to slide a mounting tray 3 at a series of continuous speeds, for use in an use environment of the highest frequency of use where the mounting tray 3 slides at a series of continuous speeds, are preset-stored in computation means 21. When the mounting tray 3 is actually slided by an output from the output motor 16, if the preset speeds are not attained, the computation means 21 outputs a command signal to the drive source 8 to appropriately correct the application voltages to the output motor 16.Type: GrantFiled: February 2, 2001Date of Patent: November 4, 2003Assignee: Koninklijke Philips Electronics N.V.Inventor: Kunio Takeda
