Motion control device

Claim 3

The device of claim 1 wherein the player-recorder unit has a pressure unit resiliently mounted adjacent the driving capstan in contact with a face of the tape of an inserted cassette opposite the face adjacent the capstan pressing the tape against the capstan when said member is in the driving position and said member sidewall portion is configured to smoothly contact a length of the tape opposite the face contacted by the pressure unit and move the tape and pressure unit away from the driving capstan when in said braking position.

Claim 4

The device of claim 2 wherein the unremoved sidewall portion of said member contacting the tape is defined by a plane extending transversely of the sidewall of said member at an acute angle to a radial from the central axis of said cavity passing through the intersection of said plane and the cavity wall.

Claim 5

The device of claim 2 wherein said integral engaging means comprises an extension of said member protruding above the face of the cassette with the end of said extension shaped to matingly engage a complementary shape on the player-recorder unit rotatable control.

Claim 6

In a cassette insertible into a player-recorder unit having a rotatable capstan for driving magnetic tape stored on rotatable drums in the cassette and having a pressure member mounted for resiliently pressing the tape of the inserted cassette into contact with the capstan, the improvement of a hollow, elongated control member having a cavity extending partially along its length from one end and into which cavity the capstan fits for free rotation, that portion of said member containing the cavity being formed from a hollow cylinder in which a portion of the sidewall along one side is cut away to expose the cavity, each face of the unremoved sidewall portion extending longitudinally of the elongated member being a planar surface extending across the sidewall at an acute angle to a radial from the longitudinal axis of said cavity, and means for mounting said member of an inserted cassette for rotation about the longitudinal axis of said cavity between (1) a driving position in which the exposed portion of the cavity faces the pressure member with the pressure unit pressing the tape into contact with the driving capstan and (2) a braking position in which one of said sidewall faces is moved against the tape to force the tape and pressure member away from the driving capstan, the other end of said elongated member having an integral portion extending above the face of said cassette and shaped to matingly engage a complementarily shaped control rotatably Mounted in the player-recorder unit.

Claim 7

In a cassette insertible into a player-recorder unit having a rotatable capstan for driving magnetic tape stored on rotatable drums in the cassette and having a pressure member mounted for resiliently pressing the tape of the inserted cassette into contact with the capstan, the improvement of a hollow, elongated control member having a cavity extending partially along its length from one end and into which cavity the capstan fits for free rotation, that portion of said member containing the cavity being formed from a hollow cylinder in which a portion of the sidewall along one side is cut away to expose the cavity, each face of the unremoved sidewall portion extending longitudinally of the elongated member being a planar surface extending across the sidewall at an acute angle to a radial from the longitudinal axis of said cavity, and means for mounting said member of an inserted cassette for rotation about the longitudinal axis of said cavity between (1) a driving position in which the exposed portion of the cavity faces the pressure member with the pressure unit pressing the tape into contact with the driving capstan and (2) a braking position in which one of said sidewall faces is moved against the tape to force the tape and pressure member away from the driving capstan, the other end of said elongated member having an integral portion extending above the face of said cassette and shaped to matingly engage a complementarily shaped control rotatably Mounted in the player-recorder unit.
