Tape cassette loading system for a magnetic recording and reproducing apparatus

A tape cassette loading system for a magnetic recording and reproducing apparatus comprising:

• a cassette holder means for holding a tape cassette, capable of being moved between a cassette inserting position where a tape cassette is inserted therein and a cassette mounting position where a tape cassette is mounted on reel mounts;
• cassette holder driving means having a first motor means for driving the cassette holder means;
• tape loading driving means for driving a tape loading means for pulling a tape from a tape cassette mounted on the reel mounts, said tape loading driving means including a second motor means for driving said tape loading driving means;
• a reel mount shifting means for varying a distance between the reel mounts of a pair of reels, said reel mount shifting means including a third motor means for driving said reel mount shifting means;
• a single power circuit for supplying power to the cassette holder driving means, the tape loading driving means, and the reel mount shifting means;
• and
• control means for connecting the power circuit alternately to the first, the second and the third motor means in a time sharing mode.

A tape cassette loading system for a magnetic recording and reproducing apparatus capable of operating with a plurality of kinds of tape cassettes differing from each other in the distance between the centers of a pair of reels contained therein for carrying a tape, comprising:

• a cassette holder for holding a tape cassette, capable of being moved between a cassette inserting position where a tape cassette is inserted therein and a cassette mounting position where a tape cassette is mounted on reel mounts:
• tape loading means for pulling out a tape from a tape cassette mounted on the reel mounts and winding the tape around a rotary drum;
• reel mount shifting means driving means for driving a reel mount shifting means for varying a distance between the centers of a pair of reel mounts according to the center distance between a pair of reels of a tape cassette to be used;
• cassette holder driving means for driving the cassette holder;
• tape loading means driving means for driving the tape loading means;
• a single power circuit for supplying power to the reel mount shifting means driving means, to the cassette holder driving means and to the tape loading means driving means;
• and
• control means for connecting the power circuit sequentially to the reel mount shifting means driving means, to the cassette holder driving means, and to the tape loading means driving means in a time sharing mode.
