Abstract
An automatic tape loading type recording and/or reproducing apparatus comprises a mechanism for loading a tape in a predetermined path in which the tape makes contact with a guide drum by intercepting and drawing the tape out of the tape cassette, a mechanism for moving the tape in the predetermined path in forward and reverse directions depending on a mode of the apparatus, a tension control mechanism for controlling a tension in the tape and comprising a tension arm and a braking member which acts on a supply reel disc, a cam mechanism for operating a braking system which is provided with respect to supply and take-up reel discs and comprising a cam body which rotates in response to the mode of the apparatus, a cam controlling mechanism responsive to a reverse reproduction mode of the apparatus, for rotating the cam body to a predetermined rotational position which is different from a rotational position of the cam body during a normal recording or reproducing mode of the apparatus, and a mechanism operated in response to the rotation of the cam body to the predetermined rotational position, for causing the tension control mechanism to assume an inoperative state by rotating the …
