Recording/reproducing apparatus with single motor for operating tape loading mechanism, pinch roller driving mechanism, reel driving mechanism, brake mechanism and mode identifying mechanism

A magnetic recording/reproducing apparatus comprising:

• a deck including a rotating head drum, a capstan motor having a shaft, and a pinch roller disposed adjacent to said head drum, and two reel driving tables onto which a tape reel of a tape cassette having a tape is seated;
• a motor installed in said deck for generating power;
• a cassette loader for loading/unloading the tape cassette onto/from said two reel driving tables;
• a master gear member rotated by said motor;
• a main slide member having a rack gear engaged with said master gear member;
• a tape loader, interlocked with said main slide member, for loading the tape of said tape cassette toward said head drum;
• a pinch roller driver for driving a pinch roller, said pinch roller driver interlocked with said main slide member, such that said pinch roller is either pressed against or separated from the shaft of said capstan motor, and the tape is pressingly transferred;
• a reel driver, interlocked with said main slide member, for selectively driving said two reel driving tables;
• a brake, interlocked with said main slide member, for selectively braking said two reel driving tables;
• and
• a mode identifier, interlocked with said cassette loader, for determining a recording feasibility of the tape;
• wherein said reel driver includes a drive pulley installed between said two reel driving tables and which is rotatably driven by power from said capstan motor, an idler rotated by the same torque as that of said drive pulley, a rotation member for rotatably supporting said idler on said drive pulley, and an operation lever which separates said idler from said two reel driving tables to shut off the power;
• and
• wherein said operation lever is constituted such that an interlocking member, having in a first end thereof a coupling hole that is coupled to an interlocking pin formed under said rotation member and having a projection formed in a second end, is rotatably installed on said deck and a cam groove to which said projection of the interlocking member is coupled is formed in said main slide member,
• whereby said interlocking member and said rotation member rotate according to movement of said main slide member, so that said idler is separated from said two reel driving tables.
