Recording and/or playback apparatus

Claim 2

In a recording and/or playback apparatus, an operating device locking mechanism comprising: a first operating device for conditioning the apparatus for normal transport of a record carrier, said device being movable from a non-operative to an operative state; a second operating device for conditioning the apparatus at least for rewind transport of the record carrier, said device being movable from a non-operative to an operative state; means responsive to movement of said second operating device to an operative state for cancelling a function for which the apparatus is conditioned by said first operating device only for the time during which said second operating device is in an operative state; common locking means responsive to the state of said first operating device for locking said first operating device in the operative state, and for locking said second operating device in an operative state upon movement from the non-operative state to an operative state only if said first device is in the non-operative state at a time said movement is initiated; and means for releasing said common locking means.

Claim 3

An operating device locking mechanism as claimed in claim 1 wherein said second operating device is movable into either of two operative states for conditioning said apparatus for rewind transport of the record carrier in the first of the operative states, and for conditioning for fast/forward transport of the record carrier in the other operative state.

Claim 4

An operating device locking mechanism as claimed in claim 1 wherein said common locking means comprises means for releasing said second operating device from a locked operative state upon movement of said first device from the non-operative to the operative state.

Claim 5

An operating device locking mechanism for a recording and/or playback apparatus, comprising: a first operating device for conditioning the apparatus for normal transport of a record carrier, said device being movable from a non-operative to an operative state; a second operating device for conditioning the apparatus at least for rewind transport of the record carrier, said device being movable from a non-operative to an operative state; means responsive to movement of said second operating device to an operative state for cancelling a function for which the apparatus is conditioned by said first operating device only for the time during which said second operating device is in an operative state; common locking means comprising a locking member, means for biassing said locking member toward a firSt position in which said operating devices are unlocked, means for moving said member into second and third positions in response to a movement of said devices, said member being moved into said second position upon movement of said second device from the non-operative to an operative state while said first device is in the non-operative state, so as to engage a portion of and to lock said second device in the operative state, said member being moved into the third position upon movement of said first device from the non-operative to the operative state so as to lock said first device in the operative state, said second device being unlocked at all times that said member is in said third position, and means for releasing said second operating device from a locked operative state upon movement of said first device from the non-operative to the operative state; and means for releasing said common locking means.

Claim 6

An operating device locking mechanism for a recording and/or playback apparatus, comprising: a first operating device for conditioning the apparatus for normal transport of a record carrier, said device being movable from a non-operative to an operative state; a second operating device for conditioning the apparatus at least for rewind transport of the record carrier, said device being movable from a non-operative to an operative state; means responsive to movement of said second operating device to an operative state for cancelling a function for which the apparatus is conditioned by said first operating device only for the time during which said second operating device is in an operative state; common locking means comprising a locking member, means for biassing said locking member toward a firSt position in which said operating devices are unlocked, means for moving said member into second and third positions in response to a movement of said devices, said member being moved into said second position upon movement of said second device from the non-operative to an operative state while said first device is in the non-operative state, so as to engage a portion of and to lock said second device in the operative state, said member being moved into the third position upon movement of said first device from the non-operative to the operative state so as to lock said first device in the operative state, said second device being unlocked at all times that said member is in said third position, and means for releasing said second operating device from a locked operative state upon movement of said first device from the non-operative to the operative state; and means for releasing said common locking means.

Claim 7

An operating device locking mechanism as claimed in claim 4 wherein said second operating device is movable into either of two operative states for conditioning said apparatus for rewind transport of the record carrier in the first of the operative states, and for conditioning for fast/forward transport of the record carrier in the other operative state.
