    摘要： A recording and/or reproducing apparatus includes a rack mechanism by which a cassette compartment can be easily removed from a mechanical deck regardless of any position at which reel tables are moved. In a recording and/or reproducing apparatus such as a video cassette recorder in which a space between two reel tables can be moved by a reel table movement mechanism and small and large tape cassettes of different size are selectively mounted on the reel tables, a rack mechanism has a pair of parallel racks which can be relatively moved through a pinion, one rack has an engagement recess formed on one end portion thereof, the other rack has an engagement recess formed on one end portion thereof, the engagement recess being positioned over the one rack and a cassette compartment includes a drive lever which is moved in the height direction in response to the insertion of tape cassettes of different size. When the drive lever is lowered, the drive lever is engaged with the engagement recess of the one rack thereby to slidably move the rack member so that the reel tables are moved to the position corresponding to the small tape cassette. When the drive lever is elevated, the drive lever is engaged with the engagement recess of the other rack thereby to slidably move the rack so that the reel tables are moved to the position corresponding to the large tape cassette.

    摘要： To provide a recording and reproducing apparatus which permits to use tape cassettes different in not only size but also thickness. In order to make the apparatus cope with the tape cassettes different in size and thickness, there is provided a positioning guide mechanism including a pair of positioning guide members so that a small cassette can be guided at both the side faces on a cassette supporting surface of the cassette holder so as to be depressed and projected by a biasing means, and a pair of side plates at its both sides of a cassette holder so that a large cassette can be guided at its both side faces. If a user is not highly skilled in operating such recording and reproducing apparatus which permits to use tape cassettes different in size and thickness, the apparatus will suffer from risk that the cassettes are erroneously inserted or the user carries out malicious operation. In order to avoid a trouble due to such erroneous insertion, malicious operation or the like, the recording and reproducing apparatus further includes a cassette insertion detecting switch mechanism useful for detecting the insertion of the cassette and leading the cassette into the cassette holder and a holder stopper mechanism composed of a holder unlocking member and a lock member.

    摘要： A tape-loading mechanism of a magnetic recording and reproducing apparatus according to the present invention has a tape travel system in which a magnetic tape drawn out of a supply-side tape reel is helically wound around a drum along a lead thereof by tilted guides respectively provided on inlet and outlet sides of the drum and tape guides respectively provided on inlet and outlet sides thereof, passed via a capstan and wound around a takeup side tape reel. A vertical position of the lead of the drum is set equal to that of a lower edge of the tape in a state immediately before the magnetic tape is loaded onto the drum. The magnetic tape is twisted in the middle of the tape travel system in order to cancel difference in tension between upper and lower edges of the magnetic tape when the magnetic tape is loaded onto the drum.

    摘要： A recording and reproducing apparatus can translate a detecting device for detecting information, such as the kind and content of tape cassette and a reel lock mechanism releasing device to proper positions corresponding to tape cassettes of different sizes. A tape cassette information detecting device (71) and reel lock releasing device (72a, 72b) can be translated to positions at which large and small tape cassettes are in use through a swing drive member (54), a translating lever (73), a driving link (74), a detection mechanism holding member (75) and a reel lock releasing plate (77) in unison with a movement of reel mounts (44, 45).

    摘要： In a tape cassette having a case with a mouth for receiving a magnetic head drum of a recording/reproducing apparatus and containing a recording tape wound on rotatable reels and including a tape run extending across the mouth; a front lid is pivotally supported on side walls of the case so as to be movable between a closed position covering a front opening of the mouth and opened position to uncover the tape run, and upper lid is pivotally joined at its front edge to the upper edge portion of the front lid so as to be movable between a closed position to covering a top opening of the mouth and opened position to uncover the top opening, and a slide shutter is supported on the case for sliding between a closed position covering a bottom opening of the mouth and opened position to uncover such bottom opening. The mouth across which a run of the recording tape extends can be closely covered by the front lid, the upper lid and the slide shutter when the tape cassette is not in use. When the tape cassette is in use, the mouth is fully opened in response to the movements of the front lid, upper lid and slide shutter to this opened position so as to enable the magnetic head drum to advance deep into the mouth.
