Claims: What is claimed and desired to be secured by Letter Patent of the United States is:

1. A tape transport apparatus for cassette type tape recorder comprising:

a. a lift deck means engaging a tape cassette, which is movable between a first position wherein the cassette is retained in a stationary position, and a second position which allows insertion or removal of the cassette from the tape recorder;

b. means to move said lift deck means in a first direction from said first position to an intermediate position and in a second direction perpendicular to said first direction from said intermediate position to said second position;

c. an electric motor for rotating a capstan and at least one reel driving spindle in the forward or backward direction;

d. a carriage means supporting a magnetic transducer head means, said carriage movable between a first position wherein the transducer head is in contact with the tape in a cassette and a second position displaced from said first position by a predetermined distance;

e. a pinch roller adapted to engage said capstan when said carriage means is in said first position;

f. means to control said electric motor so as to rotate the supply reel in the backward or rewind direction when the lift deck means is placed in the first position;

g. means for detecting the rotation of a take-up reel driving spindle in the backward direction so as to switch the rotating direction of said electric motor, and

h. means for detecting the starting of rotation of said capstan in the forward direction to shift said carriage means from said second position to said first position.

2. A tape transport apparatus for cassette type tape recorder comprising:

a. a lift deck means engaging a tape cassette, which is movable between a first position wherein the cassette is retained in a stationary position, and a second position which allows insertion or removal of the cassette from the tape recorder;

b. means to move said lift deck means in a first direction from said first position to an intermediate position and in a second direction perpendicular to said first direction from said intermediate position to said second position;

c. electric motor for rotating a capstan and at least one reel driving spindle in the forward or backward direction,

d. carriage means supporting a magnetic transducer head means, said carriage movable between a first position wherein the transducer head is in contact with the tape in a cassette and a second position displaced from said first position by a predetermined distance,

e. pinch roller means adapted to be pressed against said capstan when said carriage means is shifted from said second position to said first position,

f. means to control said electric motor so as to rotate said reel driving spindle in the backward or rewind direction when the tape cassette is placed in the first position,

g. means for detecting the rotation of a take-up reel driving spindle in the backward direction so as to switch the rotating direction of said electric motor,

h. first lever means to be caused to rotate by contact with a pin secured to a fly wheel rotating with said capstan when said capstan is rotated in the forward direction, due to the switching of rotating direction of said motor, a predetermined angle,

i. second lever means for retaining said carriage means in said first position by engagement with a pin secured to said carriage when said carriage means is in said first position, and for being moved to a position disengaging with said pin when said first lever means is rotated, and

j. third lever means for shifting said first lever means to a position in which said first lever means is disengaged from said pin secured to said flywheel by engaging said pin secured to said carriage means when the carriage means is moved into said second position.
