Title: Tape transport apparatus for cassette type tape recorder

Abstract: A cassette tape recorder has function of eliminating the slack of magnetic tape between supply reel and take-up reel in advance before the magnetic tape is started to transfer in the required direction for recording or reproducing. When the tape cassette is placed in "play" position, supply reel is rotated first in backward direction to eliminate the slack of the magnetic tape. The tensioned magnetic tape, then, may cause the take-up reel to rotate in the rewind direction. A detection device is provided to discriminate the rotation of the take-up reel in the backward direction. The detection device causes a control device for drive motor to switch the rotating direction of the motor so as to reverse the rotating direction of the capstan and the take-up reel.
