Abstract

Abstract In a disc-record player with a mechanism for loading a disc (29) onto the turntable there are provided transfer means (5) comprising a frame (8) and a disc holder (6) which can be slid into and out of said frame and which can be lowered therewith axially past the turntable (27) into a lower position in which the disc is supported on the turntable and is clear of the disc holder. The disc holder comprises a plurality of spring-loaded catches (46) which are arranged circumferentially around the disc (29) and which are movable in the radial direction. There is provided a plurality of stationary upwardly directed release elements (55) with conical end portions (55a), which, relative to guide means for the transfer means and a disc-pressure member, occupy positions such that the catches (46) are released when the transfer means are lowered past the turntable (27), whereupon the disc-pressure member (32) urges the disc (29) against the turntable (27). Near each catch (46) the disc holder (6 ) has a surface (49, 50) for supporting the disc and the disc holder is open at the upper side.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 155 words
A cartridge for loading a disc onto the turntable of a disc player and for holding said disc prior to loading, said cartridge including an upper side and a lower side, said cartridge having cylindrical wall portions defining a cylindrical space for receiving said disc, said space being completely open towards the upper side of the cartridge, said cartridge having latching means comprising a plurality of latching elements arranged adjacent said cylindrical wall to axially latch said disc and having a supporting surface adjacent each latching element for axially supporting said disc on one side and having an opening in a lower side, said opening being arranged such that said turntable extends therethrough when said disc is loaded onto the turntable, at least one of said latching elements being resiliently loaded radially toward the cylindrical space to retain said disc therein and radially movable away from said space for releasing said disc from said cartridge.
Claim 2
Dependent Claim 155 words
A cartridge for loading a disc onto the turntable of a disc player and for holding said disc prior to loading, said cartridge including an upper side and a lower side, said cartridge having cylindrical wall portions defining a cylindrical space for receiving said disc, said space being completely open towards the upper side of the cartridge, said cartridge having latching means comprising a plurality of latching elements arranged adjacent said cylindrical wall to axially latch said disc and having a supporting surface adjacent each latching element for axially supporting said disc on one side and having an opening in a lower side, said opening being arranged such that said turntable extends therethrough when said disc is loaded onto the turntable, at least one of said latching elements being resiliently loaded radially toward the cylindrical space to retain said disc therein and radially movable away from said space for releasing said disc from said cartridge.
Claim 3
Dependent Claim 28 words
A cartridge as in claim 1 further comprising apertures in said cylindrical wall and in said supporting surface to enable the displacement of said radially movable latching element.
Claim 4
Dependent Claim 48 words
A cartridge as in claim 1, wherein the cartridge comprises a bottom wall at the lower side, which wall adjoins the supporting surface adjacent a first one of said latching elements and extends across the bottom of a front part of the space bounded by the cylindrical wall.
Claim 5
Dependent Claim 47 words
A cartridge as in claim 3, wherein the bottom wall carries a pointed support which is arranged so that it contacts a disc in the cartridge only near the center hole of the disc, at that part of the disc surface where no essential information is stored.
Claim 6
Dependent Claim 36 words
A cartridge as in claim 3, wherein the cartridge comprises a grip portion which is arranged at the front of the cartridge, said first latching element being arranged between said grip portion and said bottom wall.
