Tray loading type magnetic recording and reproducing apparatus for different size tape cassettes

A tray loading type magnetic recording and reproducing apparatus, comprising:

• a deck mechanism for accommodating different size tape cassettes;
• a cassette housing affixed to an upper portion of said deck mechanism;
• and
• a cassette tray rectilinearly combined with said cassette housing, wherein said cassette tray moves back and forth and selectively accommodates said different size tape cassettes,
• wherein said deck mechanism includes a loading plate comprising a plurality of cam grooves for respectively driving a tension lever, a pinch arm, a review arm and tension poles, which is rectilinearly moved back and forth by a loading motor, for loading and unloading said different size tape cassettes.

A tray loading type magnetic recording and reproducing apparatus, comprising:

• a deck mechanism for accommodating different size tape cassettes;
• a cassette housing affixed to an upper portion of said deck mechanism;
• and
• a cassette tray rectilinearly combined with said cassette housing, wherein said cassette tray moves back and forth and selectively accommodates said different size tape cassettes,
• wherein said deck mechanism fixes a light emitting sensor and a light receiving sensor at a predetermined portion on a main chassis which is adjacent to a tension lever mounted thereon, and when said tape cassette is received on said main chassis, an element operatively associated with said tension lever passes through said light emitting sensor and said light receiving sensor according to a strength of said tape tension at an end portion of said tension lever, and controls torque of a reel motor by an amount of sensing light from said light emitting sensor and said light receiving sensor.
