Abstract
Abstract A collapsible magnetic tape cassette includes a housing having collapsible front, rear, and side panels that permit the housing to be presented in a collapsed, essentially flat form for storage, packaging, and mailing purposes and that also permit the user to later expand the housing to a normal erected form for playback purposes. A loop of magnetic tape is stored and guided within the cassette housing in a horizontal or flat position and is then guided to the vertical position as it exits the cassette housing during playback.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
238 words
A magnetic tape cassette expandable from a collapsed form of minimum height for storage and shipping to an erected form of normal height for use with a playback machine, the magnetic tape cassette comprising: a housing comprising spaced apart top and bottom panels, left and right side panels, a rear panel, and a front panel, said left and right side panels and said rear panel each being connected to said top and bottom panels and each being adjustable in height, said front panel being hingedly attached to said bottom panel for motion between a vertical position when said magnetic tape cassette is in said erected form and an inwardly directed, substantially horizontal position when said magnetic tape cassette is in said collapsed form, said front panel including a tape entry aperture and a tape exit aperture; and tape holder means positioned within said housing and attached to said bottom panel, said tape holder means being operative for storing a substantial portion of a continuous loop of magnetic tape in a horizontal position such that the plane of the magnetic tape is parallel to said top and bottom panels, said tape holder means including tape guide means for guiding said loop of magnetic tape to a vertical position for exiting said housing at said tape exit aperture and for guiding said loop of magnetic tape to the horizontal position following entry into said housing at said tape entry aperture.
