    摘要: In a magnetic video tape recorder of the cassette type with a tape tension controller comprising a tension detection arm one end of which contacts with one surface of a magnetic tape drawn from the cassette in order to detect the change of the tension in the magnetic tape there is provided a pair of roller pins each is positioned at each side of the detection arm and contacts another surface of the magnetic tape. Since the magnetic tape is turned down with an acute angle at one end of the detecting area, the detecting arm can fully detect the change of the tension.

    摘要: A helical scanning type of magnetic recording/reproducing apparatus in which a first entrance-side tape height regulation guide is disposed in a level higher than a center of a plane of rotation of magnetic heads mounted on a rotary drum assembly when the magnetic tape is loaded on the rotary drum assembly, and a first exit-side tape height regulation guide is disposed in a level lower than the center of the plane of rotation of the magnetic heads. The rotary drum assembly is disposed in a higher position such that its upper end is in the same level as an upper end of a lid of a tape cassette. The cassette is disposed at a lever lower than that of the first exit-side tape height regulation guide. The first entrance-side and the first exit-side tape height regulation guides are driven by a loading ring inclined towards the cassette so as to move while engaging with the magnetic tape during loading or unloading. A capstan motor is accommodated in a space formed between the inclined loading ring and a main chassis. This construction enables reductions in the overall thickness and the weight of the apparatus.

    摘要: A tape guide mechanism for a VTR includes a pair of first guides disposed respectively at a tape entrance side and a tape exit side of a cylinder and positioned immediately adjacent to the cylinder, a pair of second guides disposed adjacent to the pair of first guides, respectively, and a third guide provided in a path of travel of a tape extending between the first guides and the second guides, so as to prevent opposed surfaces of the tape, disposed respectively at the tape entrance side and the tape exit side, from being contacted with each other. The third guide may be of a rotary type and be disposed more remote from the cylinder than the first guides.

    摘要: A magnetic recording/reproducing apparatus for recording onto or reproducing from a magnetic tape housed in a cassette by using a rotary magnetic head having a tape withdrawal arrangement for winding a portion of the tape between the two reels in the cassette around the rotary magnetic head by a predetermined angle. A tape drive feed the magnetic tape at a constant speed, with a reel drive being provided for driving either one of the two reels so as to take up the magnetic tape in the reel driven by the reel drive, and with brake arrangement for braking the rotation of the reels. A ring-shaped cam operating member is provided in the outer peripheral surface or the inner peripheral surface thereof with cam surfaces each for effecting the operation of the respective elements in response to the mode of operation of the magnetic recording/reproducing apparatus. The selective operation is specifically determined by the rotational position of the ring-shaped cam operating member, and the rotational position is varied in response to the mode of operation. A detector is provided for detecting the rotational positions in the ring-shaped cam operating member.
