ープレコーダ。[Claims for Utility Model Registration] A video tape loading means for loading a video tape on a rotating head, a cam rotatably driven by a motor, and a tension arm that is interlocked with the cam and swings in accordance with the stroke of the cam. and a tension arm drive mechanism for moving the tension arm, wherein the cam maintains a first stroke that causes the tension arm to be held in an inoperative position within a first predetermined rotation angle range. and within a second predetermined rotational angle, a second stroke is maintained which maintains the tension arm in a weak contact actuation position that provides a relatively weak tension on the video tape mounted on the rotating head. and within a third predetermined rotational angle, a third stroke is maintained which maintains the tension arm in a strong contact operating position that provides a relatively strong tension on the video tape mounted on the rotating head. What is claimed is: 1. A video tape recorder comprising:
