Abstract
A magnetic recording and/or reproducing apparatus arranged to permit each of tape a plurality of types of tape cassettes having different distances between reels to be selectively mounted on the apparatus by moving reel mounts with a reel mount moving mechanism and to allow a tape pulled from the reels to travel while mechanically controlling the tension of the tape with a tape tension control mechanism in recording or reproducing information on or from the tape is provided with a change-over mechanism for changing the radius of swing of a tape tension detecting guide of the tape tension control mechanism from one radius over to another, and a moving mechanism for moving the tape tension control mechanism in such a way as to vary the radius of swing of the tape tension detecting guide according to the distance between the reels. The moving mechanism for moving the tape tension control mechanism and the change-over mechanism for change-over of the radius of swing are arranged to act along with the action of the reel mount moving mechanism.
