Abstract
A tape cassette for a recording and reproducing apparatus, for example, a video tape recorder, has: a cassette housing which passes a tape housed therein along an opening in the front surface thereof; a front cover pivotally attached to the cassette housing such as to cover the front side of the passed tape; a rear cover pivotally attached to the front cover such as to cover the rear side of the passed tape; a pin to be guided and provided on the rear cover; and a guide groove provided on the cassette housing such as to guide the pin. When the front cover is pivoted in the cover-opening direction, the pin is guided along the guide groove, whereby the rear cover, together with the front cover, is pivoted in the cover-opening direction while the lower end portion of the rear cover is being pivoted with respect to the front cover so as to separate to the rear of the front cover. In the tape cassette, the front surface of the lower end portion of the rear cover has a slanted surface which is slanted backwardly from its lower end towad its upper end, and further, this slanted surface is set such that, in a state wherein the front and rear covers are closed, the slanted surface is located at a position where an upper corner portion of the slanted surface is substantially flush with the lower back surface of the front cover or a position where the upper corner portion is rearward of the lower back surface of the front cover. By thus setting the slanted surface, when the rear cover is closed, the upper corner portion of the front surface of the rear cover is allowed to move such as to greatly separate to the rear of the magnetic tape, thereby making it possible to prevent the magnetic tape from being caught and damaged by the upper corner portion of the rear cover.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
