Abstract
A magazine adapted to be received at a station having spaced side guide members for receiving a portion of the magazine therebetween. The magazine comprises a hub portion; an endless length of tape having a 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 the path for the strip material around the side surface of the coil which is adapted to be received between the guide members, and a second case portion enclosing the coil which can be wider than the first case portion to provide clearance space for a coil wider than the first case portion.
Claims6
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.
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.
