Abstract

Abstract A reproducing apparatus for information-carrying records, which apparatus comprises: a housing with an opening for inserting such records, which opening is situated at housing front, a drive mechanism for the rotary drive of the records about an axis of rotation, which mechanism is accommodated in the housing, a turntable for supporting the records, which turntable is axially movable between a lowered position and an operating position, and a lifting device for moving the turntable between the lowered position and the operating position, in which apparatus there is provided a support (14), which supports the turntable (13) in the lowered position, the turntable (13) can be lifted off the support (14) into the operating position by means of the lifting device (35, 45, 47, 49, 51), and there is provided a positioning device (11) for moving the support (14) and the turntable (13) carried by said support between the lowered position of the turntable and a position in which it extends at least partly from the housing (3).

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 185 words
A front loading type record player, comprising: a housing; means, accommodated within said housing, for driving a record about an axis of rotation; a turntable, associated with said housing, for supporting a record placed thereon, said turntable being movable in a direction substantially transverse of said axis, between a loading position located outside of said housing and a lowered position located inside of said housing; means, slidably provided on said housing, for supporting said turntable for movement between said loading and said lowered positions; means, associated with said housing, for moving said turntable between said lowered position and an operating position at which said turntable is rotated by said driving means; characterized in that said driving means and said moving means include a coupling device rotatable about said axis of rotation and movable axially along said rotation axis from an initial position situated below said lowered position, through an intermediate position at which said device engages with said turntable, whereby said device and said turntable are movable axially along said axis, to a drive position at which said turntable is located at said operating position.
Claim 2
Dependent Claim 185 words
A front loading type record player, comprising: a housing; means, accommodated within said housing, for driving a record about an axis of rotation; a turntable, associated with said housing, for supporting a record placed thereon, said turntable being movable in a direction substantially transverse of said axis, between a loading position located outside of said housing and a lowered position located inside of said housing; means, slidably provided on said housing, for supporting said turntable for movement between said loading and said lowered positions; means, associated with said housing, for moving said turntable between said lowered position and an operating position at which said turntable is rotated by said driving means; characterized in that said driving means and said moving means include a coupling device rotatable about said axis of rotation and movable axially along said rotation axis from an initial position situated below said lowered position, through an intermediate position at which said device engages with said turntable, whereby said device and said turntable are movable axially along said axis, to a drive position at which said turntable is located at said operating position.
Claim 3
Dependent Claim 16 words
A record player as claimed in claim 1, wherein said coupling device comprises a drive platen.
Claim 4
Dependent Claim 51 words
A record player as claimed in claim 1, wherein said turntable includes a centering pin coaxial with said axis of rotation, said driving means and said moving means include a shaft and a bearing which supports said shaft, said shaft carrying said coupling device, and said bearing having a closed bottom.
Claim 5
Dependent Claim 27 words
A record player as claimed in claim 3, wherein said supporting means is provided with means for indicating the presence of a record placed on said turntable.
