Claims
- 1. In a disk player including a housing having an elongated opening extending laterally across a front wall thereof, and a rotary turntable laterally centered within said housing and spaced rearwardly from said front wall at a level below that of said elongated opening: a disk loading device for loading onto said turntable a record disk inserted into said opening, said device comprising
- a slide base mounted within said housing for sliding movement between a forward position and a rearward position;
- first and second disk guiding means mounted on said slide base so as to be disposed adjacent opposite sides, respectively, of said opening in said forward position of the slide base, each of said first and second disk guiding means including forward and rearward guide elements spaced apart in the direction of said sliding movement of the slide base, means mounting said guide elements at said level of the elongated opening for individual movements in directions generally transverse to said direction of the sliding movement, and means biasing said forward guide elements substantially transversely toward each other and said rearward guide elements substantially transversely toward each other to initial positions in which transverse distances between said forward guide elements and between said rearward guide elements, respectively, are smaller than the record disk diameter, whereby, with said slide base in said forward position, insertion of a record disk through said opening to a stabilized position in respect to said slide base causes the edge of said record disk to spread apart said forward guide elements and said rearward guide elements, respectively, until said forward and rearward guide elements of said first disk guiding means and of said second disk guiding means, respectively, are engaged with said edge of the record disk at locations spaced forwardly and rearwardly in respect to a transversely extending diameter of the disk for stabilizing the position of said record disk relative to said slide base;
- drive means operative when the inserted record disk has attained said stabilized position relative to the slide base for driving the latter to said rearward position in which the record disk in said stabilized position relative to the slide base is centered relative to said turntable;
- disk support means mounted on said slide base and being movable relative thereto between a raised position engageable from below with the undersurface of the record disk inserted through said elongated opening and a lowered position below said level of the turntable; and
- means normally maintaining said disk support means in said raised position and displacing said disk support means to said lowered position during a final increment of movement of said slide base to said rearward position.
- 2. A disk player according to claim 1; in which said locations at which said forward and rearward guide elements engage the edge of the record disk in said stabilized position of the latter are symmetrically disposed in respect to said transversely extending diameter of the disk.
- 3. A disk player according to claim 1; in which said first and second disk guiding means further include means operative in response to displacement of said slide base from said forward position for holding said forward and rearward guide elements relatively spread apart against the force of said means biasing the guide elements.
- 4. A disk player according to claim 3; in which said means for holding said forward and rearward guide elements relatively spread apart includes, for each of said first and second disk guiding means, a guiding cam member and followers connected with the respective forward and rearward guide elements and engaging said guiding cam member, said guiding cam member having a major surface portion extending parallel with said direction of sliding movement of said base and branch portions extending in said generally transverse directions from said major surface portion and receiving said followers only in said forward position of the slide base.
- 5. A disk player according to claim 4; in which said branch portion of each said guiding cam member receiving said follower connected with the respective rearward guiding element extends transversely inward from said major surface portion so that, in said forward position of the slide base, said rearward guiding elements are biased closer together than said forward guiding elements for ejecting the record disk forwardly through said opening upon return of said slide base to said forward position.
- 6. A disk player according to claim 5; in which said means for biasing the guide elements includes first spring means arranged for relatively strongly urging said rearward guiding elements toward each other and second spring means arranged for relatively weakly urging said forward guiding elements toward each other.
- 7. A disk player according to claim 1; in which said drive means includes a motor energizeable for driving said slide base from said forward position to said rearward position, switch means actuable for energizing said motor, and switch actuating means connected with said rearward guiding element of one of said disk guiding means for actuating said switch means when the respective rearward guiding element attains a position corresponding to said stabilized position of the record disk.
- 8. A disk player according to claim 7; in which said drive means further includes second switch means actuable to halt the energizing of said motor, and means on said slide base for actuating said second switch means upon said final increment of movement of said slide base to said rearward position.
- 9. A disk player according to claim 1; in which said slide base includes a base member and slide plates mounted on said base member for limited movement relative to the latter in a direction parallel to said direction of sliding movement, and means for locking said slide plates to move with said base member except during said final increment of movement; and in which said drive means effects movement of said slide base through said slide plates to effect said limited movement of the latter relative to said base member during said final increment of movement, and said disk support means is displaced to said lowered position in response to said limited movement of said slide plates relative to said base member.
