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.

摘要： A plurality of tape guides are moved to wind a magnetic tape on a rotatable cylinder when the magnetic tape is to be loaded. An auxiliary guide mounted on a chassis of a magnetic recording and/or reproducing apparatus in position is made to touch the magnetic tape during a period for which the magnetic tape is being loaded, but it does not touch the magnetic tape when the magnetic tape has been loaded. The auxiliary guide can be protruded toward the magnetic tape from between the tape guides moving to touch the magnetic tape during the period for which the magnetic tape is being loaded so that the magnetic tape can be kept to a predetermined span.

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 tape cartridge is arranged so that when an upper lid of a pocket portion of the tape cartridge is in a position for opening the upper side of the pocket portion, the upper lid is positioned above an upper surface of a casing body so that a lower surface of the upper lid faces the upper surface of the casing body through a gap in which a member of a recording/reproduction apparatus for depressing the cartridge can be placed. When the upper lid is in the position for opening the upper side of the pocket, the cartridge depressing member of the recording/reproduction apparatus is placed in the gap to depress the cartridge, whereby the cartridge can be stably depressed to and mounted in a predetermined position in the recording/reproduction apparatus when the cartridge is loaded in the apparatus.

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.
