Mechanism for controlling movements of cassette, cassette holder and head plate in tape cassette player

An operation changing mechanism for a tape cassette player comprising:

• a reversible control motor selectively rotatable in first and second directions;
• a cassette holder movable between a cassette load/eject position and a cassette operating position;
• a head plate movable to any of a plurality of positions respectively enabling operation of said cassette player in a plurality of modes;
• first, second and third separate cam means mechanically linked to said motor and mounted for reversible rotation thereby;
• a first operating member connected to and reversible moved by said first cam means for effecting reversible movement of a tape cassette within said cassette holder between an ejected position and a loaded position;
• a second operating member connected to said second cam means and said cassette holder and reversibly moved by said second cam means for effecting movement of said cassette holder from said cassette load/eject position to said cassette operating position and reversibly back to the load/eject position;
• and
• a third operating member connected to said third cam means and said head plate and reversibly moved by said third cam means for effecting reversible movement of said head plate to a selected one of said plurality of positions;
• said first, second and third operating members being moved in a sequence which depends on the direction of rotation of said motor.
