Patent ID: 7793311

Claim:
A disk apparatus in which a disk recorder is provided in a chassis, said disk recorder having: a tray movable in the forward and backward directions; a drive chassis movable in the upward and downward directions; an optical pickup arranged on said drive chassis; and a spindle motor accompanied with a turntable, and being adapted to move said drive chassis in the upward direction so that a disk placed on said tray is lifted by said turntable and rotated at a high speed to record information onto said disk through said optical pickup, wherein in said chassis, there are provided a disk repository adjacent to said disk recorder and a disk setting device for pushing disks one by one out of said disk repository to set each disk on said tray, said disk repository having: a disk placing base arranged in the vicinity of said tray with the upper surface thereof being positioned slightly above said tray; a guide frame having an approximate U shape when viewed from above with the inside diameter thereof being set slightly greater than the outside diameter of said disk and arranged above said disk placing base with a clearance greater than one disk's worth of thickness but smaller than two disks' worth of thickness from the upper surface of said disk placing base; and an opening and closing door arranged openably at a disk insertion slot that is opened in the front surface of said chassis in such a manner as to face said guide frame, said disk setting device having: a push-out plate arranged on said disk placing base movably in the horizontal direction and passable through said clearance between said disk placing base and said guide frame with the thickness thereof being set smaller than one disk's worth of thickness; a rack provided integrally on said push-out plate in a protruding manner; and a pinion to be engaged with said rack, it being arranged that when said pinion is driven in the normal direction to cause said push-out plate to enter said clearance between said disk placing base and said guide frame and to push only one disk out of said guide frame to set said disk on said tray, the length of a portion of said push-out plate entering said guide frame is equal to or greater than one-half of the inside diameter of said guide frame, and wherein said opening and closing door is adapted to be opened to insert disks in said guide frame through said disk insertion slot and to place said disks on said disk placing base, and then said pinion in said disk setting device is adapted to be driven in the normal direction to cause said push-out plate to enter said clearance between said disk placing base and said guide frame and to push only one disk out of said guide frame to set said disk on said tray.
