Magnetic tape cassette with novel tape reel movement limiting means

A tape cassette comprising:

• a cassette shell housing having a through hole therein;
• a reel means rotatably mounted in said housing for rotation around a reel axis and made of a synthetic resin and adapted to have a magnetic tape wound thereon, and displaceable in said housing in the direction of said reel axis;
• a flat plate-like metallic plate spring having a base end fixed to an inner face of said housing and a free end directly engaging and urging an upper surface of said reel means in the direction of said reel axis toward a wall of said housing on the opposite side of said housing from said through hole;
• and
• a reel displacing amount reducing means having an engaging portion within said housing engaging said plate spring and an exposed portion extending through said through hole, said reel displacing amount reducing means being movable in said through hole in the direction of said reel axis between a projected position in which said exposed portion projects outside said housing and a retracted position in which said exposed portion is within said through hole, and said engaging portion urges said plate spring against said reel means in resilient engagement therewith to urge said reel means against the wall of said housing on the opposite side of said housing from said through hole for holding said reel means against movement within said housing.
