摘要： A chassis is slidably provided with a circular-arc control slide bulging toward a rotary cylinder and having projections spaced apart from each other. Reel supports and a reel drive mechanism are arranged on the curving-in side of the slide. Disposed on the path of movement of the slide is a drive cam gear formed with cam grooves each extending from an outer peripheral opening toward its center. The slide is formed thereon with a toothed projection which meshes with the cam gear during a period after one of the projections is fitted in the corresponding cam groove and until the other projection is fitted in the corresponding cam groove. The slide is further formed with a cam groove having engaged therein a soft brake lever for giving a light load to the reel support in REV mode, a brake lever for lightly braking a capstan motor in SLOW mode, a tension regulator lever for lightly braking the reel support in FF/REW mode, and a withdrawing lever for withdrawing a magnetic tape from a cassette for loading to operate these levers.

摘要： A front mechanism mounted on a chassis loads a cassette in place by causing a first projection and a second projection on each of opposite side portions of a cassette carrying tray to slide along respective guide grooves formed in each of side plates. Power is transmitted from a drive cam gear provided on the rear side of the chassis to the tray via a drive mechanism, intermediate gear and rotary gear. For loading, the tray initially starts to move as inclined with the first projection and the second projection sliding along slanting grooves and is thereafter lowered by sliding movement of the projection along a vertical groove and sliding movement of the projection along a descent groove while being corrected from the inclined position to a horizontal position. Upon completion of cassette loading, the intermediate gear and the rotary gear constitute a Geneva stop, and the drive cam gear disengages from the drive mechanism. A support guide supporting the drive mechanism is provided by being formed by outsert molding inside the chassis and thereafter being rotated to project from a side portion of the chassis.

摘要： A chassis is provided with a pair of leading guide blocks slidably fitted in respective guide slots for withdrawing a tape from a cassette, loading links for slidingly moving the respective guide blocks, and catchers arranged on the chassis at a loading completed position for the respective guide blocks to come into pressing contact with. Each of the loading links comprises a pivotal lever rotatably fitting around a pivot on the chassis and a link plate connected by a pivot pin to a free end of the pivotal lever and rotatably engaged at a forward end thereof with the guide block. The chassis is formed with apertures permitting insertion of the respective guide blocks therein, each covered with the catcher and each communicating with the guide slot. The aperture is positioned at a greater distance from the pivot than the forward end of the link plate when a center line L1 connecting the pivot and the pivot pin and a center line L2 connecting the pivot pin and the portion of connection between the guide block and the link plate extend toward the direction of loading in alignment with each other.

摘要： A tape loading/unloading arrangement for use in a magnetic recording and/or reproducing apparatus, such as an 8 mm video cassette recorder, includes a pair of tape guides which pull a portion of a tape out of a tape cassette so as to extend it around a tilted guide cylinder. An improvement is made to the tape guide which comprises a support plate, an upright post perpendicularly mounted on the support plate, a slanted post mounted on the support plate adjacent the upright post for movement closely adjacent a surface of the guide cylinder, and an auxiliary post movably mounted on the support plate and adapted to be located, during the movement of the support plate between home- and operating-positions, in front of a common tangent face to the upright post and the slanted post, which common tangent face is located on the side of said upright and slanted posts facing the operating-position, but is located, when the support plate terminates at the operating-position, behind the common tangent face.
