Abstract
A video tape recorder having a tape tensioning mechanism for tensioning a magnetic tape drawn out of a tape cassette. The tape tensioning mechanism has a tensioning arm rotatably mounted on a movable Chassis, a tensioning pin for contacting the tape to tension the tape when the tape has been loaded in a predetermined tape path, a tightening lever movably mounted on the movable chassis, and a tension spring for urging the tensioning arm in a direction of rotation to bring the tensioning pin into contact with the tape. A pusher is fixedly mounted on a fixed chassis for pushing the tightening lever to tighten the tension spring substantially at the same time that the magnetic tape is loaded in the predetermined tape path. When the magnetic tape is not loaded in the tape path, the tightening lever is released from the pusher to loosen the tension spring.
