Recording and/or playback machine which affords use of various sized magazines

Claim 2

A magazine adapted to be received at a station having spaced side guide members for receiving a portion of the magazine therebetween, said magazine comprising: a generally cylindrical hub portion; an endless length of strip material having a major portion wound in a coil about the hub portion and a minor portion extending from the innermost wrap of the coil along a path around the side surface of the coil to the outermost wrap of the coil; and a case including a first case portion enclosing said path for the strip material around the side surface of the coil and comprising opposite first side wall portions positioned on opposite sides of said path for the strip material around the side surface of the coil, said first side wall portions being spaced at a predetermined distance and having outer surfaces adapted to engage and be positioned by the side guide members at a said station to provide lateral positioning of said magazine relative to said station; and a second case portion enclosing said coil and hub and comprising opposite second side wall portions generally parallel with said first side wall portions on opposite sides of said hub and coil and spaced farther apart than said first side wall portions to afford clearance space for said coil.

Claim 3

In combination: a magazine comprising: a generally cylindrical hub portion; an endless length of strip material having a major portion wound in a coil about the hub portion and a minor portion extending from the innermost wrap of the coil along a path around the side surface of the coil to the outermost wrap of the coil; and a case including a first case portion enclosing said path for the strip material around the side surface of the coil and comprising opposite first side wall portions positioned on opposite sides of said path for the strip material around the side surface of the coil, said first side wall portions being spaced at a predetermined distance and having outer surfaces; and a second case portion enclosing said coil and hub and comprising second opposite side wall portions generally parallel with said first side wall portions on opposite sides of said hub and coil; and a recording and/or playback machine comprising: means defining a station for releasably receiving and positioning said magazine in a predetermined position on said machine comprising spaced side guide members adapted for only receiving said first side wall portion of said case therebetween in close-fitting relationship to provide lateral positioning of said magazine relative to said station.

Claim 4

In combination: a magazine comprising: a generally cylindrical hub portion; an endless length of strip material having a major portion wound in a coil about the hub portion and a minor portion extending from the innermost wrap of the coil along a path around the side surface of the coil to the outermost wrap of the coil; and a case including a first case portion enclosing said path for the strip material around the side surface of the coil and comprising opposite first side wall portions positioned on opposite sides of said path for the strip material around the side surface of the coil, said first side wall portions being spaced at a predetermined distance and having outer surfaces; and a second case portion enclosing said coil and hub and comprising second opposite side wall portions generally parallel with said first side wall portions on opposite sides of said hub and coil; and a recording and/or playback machine comprising: means defining a station for releasably receiving and positioning said magazine in a predetermined position on said machine comprising spaced side guide members adapted for only receiving said first side wall portion of said case therebetween in close-fitting relationship to provide lateral positioning of said magazine relative to said station.

Claim 5

A combination according to claim 2 wherein said means for defining a station comprises a transducer means for guiding said strip material past the transducer and means for pulling said strip material past said means for guiding and said transducer; said hub has a central opening and a slot extending axially across its full width and communicating with said central opening; said minor portion of said strip material extends through said slot and partially across said central opening and then along said path around the side surface of the coil; and said means for releasably receiving and positioning includes means for affording relative movement between said magazine and said means for defining a station between a disengaged position with said magazine spaced from said transducer said means for guiding and said means for pulling, and an engaged position with said transducer said means for guiding and said means for pulling in said central opening.

Claim 6

A combination according to claim 3 wherein said means for affording relative movement comprises a movable frame portion having walls providing said guide members and defining a socket having an inlet opening adapted to slidably receive said magazine with the side walls of said first portion along said guide members, and means for mounting said frame portion on said means for defining a station for movement between said disengaged position and said engaged position.

Claim 7

A combination according to claim 4 wherein said means for defining a station comprises a top plate, said transducer said means for guiding and said means for pulling project upwardly from said top plate, said movable frame portion has side walls including said guide members and an end wall between said side walls opposite said inlet opening, and said means mounting said movable frame portion for movement comprises parallel arms each having one end pivotably mounted on said top plate and another end pivotably mounted on a different one of said side walls at its end opposite said opening to afford movement of a rear part of said movable frame portion adjacent said end wall from a first position spaced from said station to a second position more closely adjacent said station, opposite trunnions projecting outwardly from opposite sides of said movable frame portion and cam plates fixed to said top plate on opposite sides of said movable frame portion and each having edge surfaces defining a slot receiving and guiding a different one of said trunnions, said slots each having a generally horizontal portion guiding said trunnions upon movement of said part of the movable frame portion from its first to its second position, and a portion extending from said generally horizontal portion toward said top plate to afford movement of a front part of said movable frame portion adjacent said opening toward said top plate by pivoting said movable frame portion about said arms to position the magazine at said station when the magazine is in said socket.

Claim 8

A combination according to claim 2 wherein said first side wall portions are spaced farther apart than said first wall portions to afford clearance space for said coil.
