Abstract
Abstract In a disc player, such as for a rigid disc, a compartment slides on the inside of the lid between an outer position in which a disc may easily be inserted or removed, and a position in which, when the lid is closed, the disc is on a turntable. A lever, pivotally connected to the chassis and a sliding compartment in the lid, and an arm extending from the lid, are interconnected by a spring whose biasing force holds the lid in the open position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
299 words
A disc player for an information-carrying disc inserted into the player, comprising a chassis, a turntable rotatably journalled to the chassis, a lid, having a projecting arm extending therefrom, a hinge pivotally connecting the lid to the chassis for pivotable movement of the lid between first and second positions about a hinge axis located near said arm, a slide, mounted to the lid for slidable movement away from and toward the hinge between a loading position and an outer position in which the slide is farther from the hinge axis, said slide at least partly bounding a compartment arranged for receiving a disc, in said outer position said compartment extending beyond said lid such that the disc can be readily removed, means for moving the slide from the loading position to the outer position as the lid is pivoted from the first position to the second position, said means including a lever having an arm with an end portion and having an extension member, said lever being pivotably connected to the chassis at a pivot location remote from said hinge axis; and means pivotably connecting said arm end portion to said slide, arranged such that, when the lid is in the first position, the arm extends from said pivot location toward the hinge axis, and as the lid pivots from the first to the second position, the lever pivots with respect to the chassis, and said slide and lever arm end portion move away from the hinge axis, and a spring connected between said projecting arm and said extension member so as to bias the lid in the direction of pivoting from the first to the second position, in said first position of the lid said compartment being so disposed that a disc received therein is adjacent said turntable.
Claim 2
Dependent Claim
299 words
A disc player for an information-carrying disc inserted into the player, comprising a chassis, a turntable rotatably journalled to the chassis, a lid, having a projecting arm extending therefrom, a hinge pivotally connecting the lid to the chassis for pivotable movement of the lid between first and second positions about a hinge axis located near said arm, a slide, mounted to the lid for slidable movement away from and toward the hinge between a loading position and an outer position in which the slide is farther from the hinge axis, said slide at least partly bounding a compartment arranged for receiving a disc, in said outer position said compartment extending beyond said lid such that the disc can be readily removed, means for moving the slide from the loading position to the outer position as the lid is pivoted from the first position to the second position, said means including a lever having an arm with an end portion and having an extension member, said lever being pivotably connected to the chassis at a pivot location remote from said hinge axis; and means pivotably connecting said arm end portion to said slide, arranged such that, when the lid is in the first position, the arm extends from said pivot location toward the hinge axis, and as the lid pivots from the first to the second position, the lever pivots with respect to the chassis, and said slide and lever arm end portion move away from the hinge axis, and a spring connected between said projecting arm and said extension member so as to bias the lid in the direction of pivoting from the first to the second position, in said first position of the lid said compartment being so disposed that a disc received therein is adjacent said turntable.
Claim 3
Dependent Claim
79 words
A player as claimed in claim 1, characterized in that said lever arm and lever extension member extend generally perpendicular to each other from the pivot location; said lid arm extends in a direction from the hinge axis away from the lid; and said lever and lid arm are so arranged that, at least when the lid is in the first position, the chassis, the hinge axis and the pivot axis are all between said spring and said lid.
