Abstract

Abstract A miniature cassette is disclosed comprising a casing having two rotatable spools for storing magnetic tape, guide rollers mounted in the casing for guiding the tape in different paths between the spools, and apertures in the end walls of the casing allowing the tape to exit from and enter into the casing along different paths between the spools wherein one of the paths is substantially perpendicular to the end walls of the casing.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 158 words
A miniature cassette comprising: a casing having opposite end walls, two spools rotatably mounted in said casing for storing a length of magnetic tape attached at both ends to and wound around said spools, tape guide means mounted adjacent said opposite end walls of said casing for guiding said tape in paths between said spools including a short path wherein said tape exits from one guide means in a direction toward the opposite end wall and a long path wherein said tape exits from one guide means in a direction away from and substantially perpendicular to the opposite end wall, and said end walls having apertures providing clearance with said casing for said tape to exit from and enter into said casing along said short and long paths, said guide means adjacent each of said opposite ends walls providing guide surfaces for guiding the tape into the short and long paths as the tape exits from the casing.
Claim 2
Dependent Claim 158 words
A miniature cassette comprising: a casing having opposite end walls, two spools rotatably mounted in said casing for storing a length of magnetic tape attached at both ends to and wound around said spools, tape guide means mounted adjacent said opposite end walls of said casing for guiding said tape in paths between said spools including a short path wherein said tape exits from one guide means in a direction toward the opposite end wall and a long path wherein said tape exits from one guide means in a direction away from and substantially perpendicular to the opposite end wall, and said end walls having apertures providing clearance with said casing for said tape to exit from and enter into said casing along said short and long paths, said guide means adjacent each of said opposite ends walls providing guide surfaces for guiding the tape into the short and long paths as the tape exits from the casing.
Claim 3
Dependent Claim 217 words
A miniature cassette comprising: a casing having opposite end walls, two spools rotatably mounted in said casing for storing a length of magnetic tape attached at both ends to and wound around said spools, tape guide means mounted adjacent said opposite end walls of said casing for guiding said tape in paths between said spools including a short path wherein said tape exits from one guide means in a direction toward the opposite end wall and a long path wherein said tape exits from one guide means in a direction away from the opposite end wall, said guide means comprising a pair of guide rollers provided in said casing at each end of said cassette including an inward and an outward guide roller mounted adjacent each end of said casing, said tape contacting said inward roller and being trained around said outward roller in its short path of travel and being free of contact with said outward roller in its long path of travel, and said end walls having apertures for said tape to exit from and enter into said casing along said short and long paths, said guide means adjacent each of said opposite ends walls providing guide surfaces for guiding the tape into the short and long paths as the tape exits from the casing.
Claim 4
Dependent Claim 217 words
A miniature cassette comprising: a casing having opposite end walls, two spools rotatably mounted in said casing for storing a length of magnetic tape attached at both ends to and wound around said spools, tape guide means mounted adjacent said opposite end walls of said casing for guiding said tape in paths between said spools including a short path wherein said tape exits from one guide means in a direction toward the opposite end wall and a long path wherein said tape exits from one guide means in a direction away from the opposite end wall, said guide means comprising a pair of guide rollers provided in said casing at each end of said cassette including an inward and an outward guide roller mounted adjacent each end of said casing, said tape contacting said inward roller and being trained around said outward roller in its short path of travel and being free of contact with said outward roller in its long path of travel, and said end walls having apertures for said tape to exit from and enter into said casing along said short and long paths, said guide means adjacent each of said opposite ends walls providing guide surfaces for guiding the tape into the short and long paths as the tape exits from the casing.
Claim 5
Dependent Claim 209 words
A miniature cassette comprising: a casing having opposite end walls, two spools rotatably mounted in said casing for storing a length of magnetic tape attached at both ends to and wound around said spools, tape guide means mounted adjacent said opposite end walls of said casing for guiding said tape in paths between said spools including a short path wherein said tape exits from one guide means in a direction toward the opposite end wall and a long path wherein said tape exits from one guide means in a direction away from and substantially perpendicular to the opposite end wall, said guide means including a pair of rollers adjacent each end of said cassette, each pair including an inward roller and an outward roller, said tape contacting both rollers in said short path and only one of said rollers in said long path, said long path extending substantially perpendicular to the end walls of said casing, and said end walls having apertures for said tape to exit from and enter into said casing along said short and long paths, said guide means adjacent each of said opposite ends walls providing guide surfaces for guiding the tape into the short and long paths as the tape exits from the casing.
Claim 6
Dependent Claim 209 words
A miniature cassette comprising: a casing having opposite end walls, two spools rotatably mounted in said casing for storing a length of magnetic tape attached at both ends to and wound around said spools, tape guide means mounted adjacent said opposite end walls of said casing for guiding said tape in paths between said spools including a short path wherein said tape exits from one guide means in a direction toward the opposite end wall and a long path wherein said tape exits from one guide means in a direction away from and substantially perpendicular to the opposite end wall, said guide means including a pair of rollers adjacent each end of said cassette, each pair including an inward roller and an outward roller, said tape contacting both rollers in said short path and only one of said rollers in said long path, said long path extending substantially perpendicular to the end walls of said casing, and said end walls having apertures for said tape to exit from and enter into said casing along said short and long paths, said guide means adjacent each of said opposite ends walls providing guide surfaces for guiding the tape into the short and long paths as the tape exits from the casing.
