Abstract
Abstract In a disc-record player which comprises a resiliently support subframe (5) which carries a turntable (6) and a read means (9) a loading device (14) for loading a disc (15) into the record player comprises a servo means (53) which comprises a plurality of control elements for controlling the movements of the loading device (14). An insertion control element (52) cooperates with a transfer device (17, 29) to guide the disc (15) towards the turntable (6). A lift control element (57c) cooperates with the transfer device (17, 29) to control the movement of the disc (15) towards the turntable (6). A clamping-member control element (71b, 72b) controls at least two clamping members (26) of the transfer device (17, 29) which members hold the disc (15) during loading, and causes the clamping members (26) to be disengaged from the disc after the disc has been lowered onto the turntable (6). A locking means control element (71b, 72b) controls locking means (79; 80) which lock the subframe (5) and causes said latches (79; 80) to become disengaged from the subframe (5) after the disc (15) has been lowered onto the turntable (6).

Dependent Claim
257 words
A disc-record player which comprises a housing, a frame and a resiliently supported subframe which carries a turntable and a read means, and a loading device for loading a disc into the record player, which loading device comprises a transfer device which can move the disc from a front opening in the housing to a position over the turntable and subsequently towards the turntable to deposit the disc on said turntable, the movements of said transfer device being controlled by a servo means whic h is driven by a drive motor and which comprises a plurality of control elements for controlling the various movements of the loading device, of which control elements an insertion control element cooperates with the transfer device to control the insertion movement of the disc towards a position over the turntable and a lift control-element cooperates with the transfer device to guide the disc towards the turntable, characterized in that the servo means also comprises: - a clamping member control element which controls at least two clamping members of the transfer device, which clamping members hold the disc in the transfer device during loading, and are caused by the clamping member control element to be disengaged from the disc after the disc has been deposited on the turntable, and - a locking means control element which controls locking means that lock the subframe relative to the frame during loading of the disc, and which causes the locking means to be disengaged from the subframe after the disc has been deposited on the turntable.
Claim 3
Dependent Claim
67 words
A disc record player as claimed in Claim 1, the servo means is rectilinearly guided on the frame and comprises at least one servo member comprising a control plate which relative to the direction of insertion of the disc is situated adjacent the transfer device, characterized in that the control plate adjoins at least one control limb which extends from the control plate towards the transfer device.
Claim 4
Dependent Claim
34 words
A disc-record player as claimed in Claim 2, characterized in that the servo member comprises first and second control limbs which extend from the control plate on two opposite sides of the transfer device.
Claim 5
Dependent Claim
75 words
A disc-record player as claimed in any of the preceding Claims, characterized in that the transfer device comprises a disc holder containing a disc and transfer means, which disc holder is transferred into the transfer means to a position over the turntable by means of the insertion control element and is subsequently transferred with the transfer means to the turntable via the lift control element, the two clamping members forming part of the disc holder.
Claim 6
Dependent Claim
73 words
A disc-record player as claimed in Claim 4, characterized in that the disc holder becomes coupled to an actuating slide by insertion into the transfer means, the insertion control element being situated on a control limb and being coupled to the actuating slide via a pivotally mounted stroke-anplifying lever, which slide being subsequently moved by the one or the first control limb to move the disc holder until it is over the turntable.
Claim 7
Dependent Claim
60 words
A disc-record player as claimed in any one of the preceding Claims, which is also provided with a disc pressure means which is movable into a pressing position to urge the disc against the turntable, characterized in that the servo means also comprises a pressure-means control element for controlling the movement of the disc pressure means towards the pressing position.
Claim 8
Dependent Claim
85 words
A disc-record player as claimed in Claim 6, characterized in that the lift control element and the pressure means control element are constituted by, respectively, first and second inclined guideways on the control plate, each of the inclined guideways adjoining at its ends straight guideways which extend parallel to the direction of movement of the control plate and the inclined guideways being so arranged relative to each other that the movement of the disc pressure means is faster than the movement of the transfer device.
Claim 9
Dependent Claim
75 words
