Reel brake and associated tension arm control device for a reversible

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 tension arm in a predetermined direction so that the braking member becomes inoperative with respect to the supply reel disc.
