Abstract

Abstract An endless magnetic tape magazine constructed as an oblong box for use on a conventional recording/playback apparatus having a pair of winding spindles. Two pair of aligned apertures are provided through the bottom and top cover of the box. The apertures are spaced apart so as to accommodate the winding spindles of the apparatus. The magazine is provided with a rotatably mounted core about one of the apertures for accommodating a roll of endless tape, and arranged so as to rotate about the spindle passing through the aperture. Guide rollers are provided for guiding the tape along the inside of the magazine and back onto the roll and an additional pair of aligned apertures is also provided for accommodating a drive capstan and insuring correct positioning of the magazine within the recording/playback apparatus.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 324 words
A magazine for accommodating therein a single endless magnetic tape and arranged for use on a conventional recording and playback apparatus having a pair of winding spindles, said magazine comprising a housing constructed as an oblong box having a bottom, a top cover, front and back side walls and a pair of end side walls, first and second aligned pairs of aperture passing through said bottom and said top cover, said apertures being spaced apart for accommodating therethrough the winding spindles of said apparatus, a core about said second pair of apertures for supporting a roll of endless magnetic tape, said tape being unwound from the center of said roll adjacent said core and wound about its outer periphery, said core being journalled so as to be freely rotatable about the axis journalled said second aperture, said core having a central opening larger than said second aperture so that said core may rotate on the spindle passing therethrough with little friction, so that there will be no positive coupling between the core and the winding spindle, a third pair of aligned apertures passing through said bottom and top cover for accommodating a driving capstan of said apparatus, first and second guide rollers mounted between said bottom and said cover for guiding the magnetic tape which is being unwound from said endless tape roll along the inside of said front side wall and back onto the outer periphery of said roll, said second guide roller being arranged for feeding said tape back onto said roll and being located on the same side of the transverse axis of said housing as is said core, said first guide roller being located on the other side of said axis with said first pair of aligned apertures, and a plurality of apertures in said front side wall for receiving magnetic heads and a driving roller of said apparatus for engaging the tape being passed along said front side wall.
Claim 2
Dependent Claim 324 words
A magazine for accommodating therein a single endless magnetic tape and arranged for use on a conventional recording and playback apparatus having a pair of winding spindles, said magazine comprising a housing constructed as an oblong box having a bottom, a top cover, front and back side walls and a pair of end side walls, first and second aligned pairs of aperture passing through said bottom and said top cover, said apertures being spaced apart for accommodating therethrough the winding spindles of said apparatus, a core about said second pair of apertures for supporting a roll of endless magnetic tape, said tape being unwound from the center of said roll adjacent said core and wound about its outer periphery, said core being journalled so as to be freely rotatable about the axis journalled said second aperture, said core having a central opening larger than said second aperture so that said core may rotate on the spindle passing therethrough with little friction, so that there will be no positive coupling between the core and the winding spindle, a third pair of aligned apertures passing through said bottom and top cover for accommodating a driving capstan of said apparatus, first and second guide rollers mounted between said bottom and said cover for guiding the magnetic tape which is being unwound from said endless tape roll along the inside of said front side wall and back onto the outer periphery of said roll, said second guide roller being arranged for feeding said tape back onto said roll and being located on the same side of the transverse axis of said housing as is said core, said first guide roller being located on the other side of said axis with said first pair of aligned apertures, and a plurality of apertures in said front side wall for receiving magnetic heads and a driving roller of said apparatus for engaging the tape being passed along said front side wall.
Claim 3
Dependent Claim 37 words
The tape magazine according to claim 1 wherein said third pair of aligned apertures for accommodating said driving shaft is located on the same side of said housing as is said second guide roller and said core.
Claim 4
Dependent Claim 66 words
The tape magazine according to claim 2 further comprising recess on the inner surface of said top cover for guiding said tape as it leaves said roll, said recess having a depth of approximately half the thickness of said top cover, said recess extending from the point where the tape is unwound from said roll to the point where said tape engages said first guide roller.
Claim 5
Dependent Claim 43 words
The tape magazine according to claim 3 further comprising an aperture in said back side wall for receiving therein means on a recording apparatus which when in engagement with said aperture will prevent operation of fast forward and rewind functions of said apparatus.
