摘要： A video tape recorder has a tape tensioning mechanism (61) for tensioning a magnetic tape (6) drawn out of a tape cassette (2). The tape tensioning mechanism has a tensioning arm (56) angularly movably mounted on a movable chassis (16) with a tensioning pin (57) for contacting the tape to tension the tape when the tape has been loaded in a predetermined tape path, a tightening lever (65) movably mounted on the movable chassis, and a tension spring (68) for normally urging the tensioning arm in a direction to turn the tensioning arm to bring the tensioning pin into contact with the tape. A pusher (72) is fixedly mounted on a fixed chassis (14) 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. Since the tension spring is not required to bias the tensioning arm when the magnetic tape is unloaded and is only required to bias the tensioning arm when the magnetic tape is loaded, the tension spring may be of a relatively small size.

摘要： A video camera has a tape deck mechanism (1) in which a rotary head drum (16) and a tape loading device (17, 18) is inserted completely into a dead space in a tape cassette, the lid of the cassette is then closed and a recording/playback operation performed. The tape deck mechanism (1) is reduced in size by having multiple chassis (2, 3, 4) that slide into and fold over each other with the tape cassette contained therein. The tape deck mechanism (1) operates in conjunction with a special tape cassette to increase the available dead space by moving the cassette tape reels apart when the head drum chassis (3) slides into the chassis (2) holding the cassette. The lid of the cassette can be opened by a mechanism that does not require pressure against the cassette to overcome a lid-closing spring of the cassette. The tape deck mechanism can be arranged with the known video camera electronics and optics in various configurations to provide a compact video camera.
