Tape cassette

Magnetic recording and reproducing system using preceding and lagging

A tape cassette for use in a video tape recorder or the like, which includes a cassette main body having an upper case and a lower case fitted to each other to define the main body, and a front cover movably mounted on the cassette main body for covering a magnetic tape stretched along a front face of the cassette main body, and is characterized in that there are provided a protrusion formed at the lower portion of the front cover so as to extend in a direction toward the lower case, and a corresponding protruding portion formed on the lower case so as to extend in a direction toward the magnetic tape, and thus, upon closure of the front cover, the protrusion of the front cover is adapted to be located at a position below the protruding portion of the lower case.

Tape cassette with improved cover structure

An improved standard size video cassette has a top shell and a bottom shell held together so as to define a rectangular casing for storing therein a magnetic tape wound on reels. The bottom shell is formed with a groove having a width sufficiently wide to receive the projection therein with hardly any contact during cassette insertion into or ejection from the holder. An improved reduced size video cassette has a top shell and a bottom shell held together so as to define a rectangular casing for storing therein a magnetic tape wound on reels. The bottom shell is formed with the groove which is located such that a distance between the center of the groove and one end of the rectangular casing is slightly smaller than the distance between a center of the projection and one of the opposite side plates.
