Abstract
Abstract Tape cleaning apparatus comprising a platform having an upstanding wall at one end is disclosed. Upper and lower means are provided in the wall for receiving pads to clean, lubricate, and impart anti-static treatment to tape in cassettes when positioned thereagainst. Members on the platform extend thereabove for mounting and positioning cassettes with exposed tape portions in cleaning positions adjacent the pad receiving means. A first set of members, including a clip member, is positioned to engage the rear of a dual reel cassette in the lower position adjacent the platform. A second set of members is spaced rearwardly of the position of the dual reel cassette and extends thereabove to support a continuous loop cassette in an elevated position above that of the dual reel cassette, the members of the first set having a height below the minimum height above the platform of the continuous loop cassette. A pair of spindles is provided in the platform positioned to project through the reel hubs of a dual reel cassette, at least one spindle being adapted to engage the reel hub through which it projects. The engaging spindle and a roller in the upstanding wall positioned to engage tape against an idle roller in the continuous loop cassette provide the drive means for moving tape in the cassettes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
451 words
Apparatus for cleaning magnetic tapes in dual reel or continuous loop cassettes comprising: a platform adapted to be horizontally positioned; a wall extending upwardly, away from one end of said platform; a first means for receiving in said wall a first tape cleaning pad to engage exposed portions of tape in cassettes, said first pad-receiving means being spaced above said platform; a second means for receiving in said wall a second tape cleaning pad to engage exposed portions of tape in cassettes, said second pad-receiving means being spaced above said first pad receiving means; a first set of cassette-holding members extending upwardly, away from said platform and spaced from said wall, said first set of members being adapted to position and hold a first, dual reel, cassette in an operative position above said platform with its exposed tape portion positioned for contact with said first pad, a pair of said members of said first set being spaced apart in positions for supporting the rear portion of said dual reel cassette; a second set of cassette-holding members, extending upwardly, away from said platform and spaced further from said wall than said first set of members, said second set of members being adapted to position and hold a second, continuous loop, cassette in an operative position spaced above said dual reel cassette with its exposed tape portion positioned for contact with said second pad, each of said members of said second set being spaced from said wall a distance greater than the distance said dual reel cassette extends from said wall when said dual reel cassette is in its said operative position and less than the distance said continuous loop cassette extends from said wall when said continuous loop cassette is in its said operative position, the members of said second set being spaced apart a distance less than the distance between the sides of said continuous loop cassette, said members of said first set extending upwardly, away from said platform a distance less than the spacing between said platform and the continuous loop cassette when it is in its said operative position, said members of said second set extending upwardly from said platform a distance greater than the distance said dual reel cassette extends above said platform in its operative position; a pair of spindles in said platform positioned to project through the hubs of the reels of a dual reel cassette, at least one of said spindles being adapted to engage one of said hubs; and drive means for driving tapes in said cassettes, said drive means comprising said one spindle and a roller mounted in said wall positioned to engage tape against an idler roll in said continuous loop cassette.
Claim 2
Dependent Claim
451 words
Apparatus for cleaning magnetic tapes in dual reel or continuous loop cassettes comprising: a platform adapted to be horizontally positioned; a wall extending upwardly, away from one end of said platform; a first means for receiving in said wall a first tape cleaning pad to engage exposed portions of tape in cassettes, said first pad-receiving means being spaced above said platform; a second means for receiving in said wall a second tape cleaning pad to engage exposed portions of tape in cassettes, said second pad-receiving means being spaced above said first pad receiving means; a first set of cassette-holding members extending upwardly, away from said platform and spaced from said wall, said first set of members being adapted to position and hold a first, dual reel, cassette in an operative position above said platform with its exposed tape portion positioned for contact with said first pad, a pair of said members of said first set being spaced apart in positions for supporting the rear portion of said dual reel cassette; a second set of cassette-holding members, extending upwardly, away from said platform and spaced further from said wall than said first set of members, said second set of members being adapted to position and hold a second, continuous loop, cassette in an operative position spaced above said dual reel cassette with its exposed tape portion positioned for contact with said second pad, each of said members of said second set being spaced from said wall a distance greater than the distance said dual reel cassette extends from said wall when said dual reel cassette is in its said operative position and less than the distance said continuous loop cassette extends from said wall when said continuous loop cassette is in its said operative position, the members of said second set being spaced apart a distance less than the distance between the sides of said continuous loop cassette, said members of said first set extending upwardly, away from said platform a distance less than the spacing between said platform and the continuous loop cassette when it is in its said operative position, said members of said second set extending upwardly from said platform a distance greater than the distance said dual reel cassette extends above said platform in its operative position; a pair of spindles in said platform positioned to project through the hubs of the reels of a dual reel cassette, at least one of said spindles being adapted to engage one of said hubs; and drive means for driving tapes in said cassettes, said drive means comprising said one spindle and a roller mounted in said wall positioned to engage tape against an idler roll in said continuous loop cassette.
Claim 3
Dependent Claim
58 words
The apparatus claimed in claim 1 further comprising upper and lower recesses in said wall sized, respectively, to receive therein the portions of said second and first cassettes having exposed portions of tape for restraining movement of said cassettes; said roller exposed in said upper recess; and said upper and lower pad receiving means positioned in said recesses.
Claim 4
Dependent Claim
83 words
The apparatus claimed in claim 2 further comprising angular surfaces on the sides of said upper recess adapted to engage corresponding angular walls on said second, continuous loop, cassette, and post members positioned adjacent the sides of said platform, one said post member having means for locking engagement in a notch recess in said second cassette, the height of said post members above said platform being greater than the height of said first cassette when it is positioned in its said operating position.
Claim 5
Dependent Claim
19 words
The apparatus claimed in claim 3 wherein said post members extend from said upstanding wall and overhang said platform.
Claim 6
Dependent Claim
