摘要： A cassette holder holds a cassette, and is disposed to be substantially horizontally movable. A loading mechanism includes a guide member for guiding the cassette holder to load or unload the cassette, and a worm wheel for driving the guide member. A worm unit includes a worm, having first and second ends, meshed with the worm wheel, a rotating member coaxially mounted to the first end of the worm, and thrust and radial bearings coaxially mounted between the worm and the rotating member, the worm being driven in accordance with a transmission of rotation from a drive source to the rotating member. A mounting mechanism, to which the worm unit is mounted, includes a first elastic support member for elastically supporting the second end of the worm, and a second elastic support member for elastically supporting the radial bearing.

摘要： A disc stored in a casing is inserted in an apparatus for reproducing signals from the disc. The apparatus comprises: a housing having at one side an inlet through which the casing is inserted, a cover movable between a close position where it closes the inlet of the housing and an opening position where it opens the inlet, and a locking mechanism for preventing the cover from moving to the opening position when signals are reproduced from the disc and for moving the cover to the opening position when signals are not reproduced from the disc.

摘要： A tray unit is moved into a housing or partially pulled out from the housing by a horizontal motor provided in the housing. Since the tray unit can load a plurality of cassettes, the weight of the unit is largely changed in accordance with the number of loaded cassettes. The horizontal motor must be controlled by accurately detecting the moving position of the tray unit. The rotation of the horizontal motor is transmitted to a rotary member. The rotation of the rotary member is associated with a pulse detecting element provided on a printed circuit board for tray position detection. The moving position of the tray unit is detected by counting pulses obtained from the pulse detecting element in accordance with the rotation of the rotary member.
摘要翻译：托盘单元通过设置在壳体中的水平马达移动到壳体中或部分地从壳体中拉出。由于托盘单元可以装载多个盒，所以单元的重量根据装入的盒的数量而大大地改变。水平电机必须通过精确检测托盘单元的移动位置进行控制。水平马达的旋转被传递到旋转构件。旋转构件的旋转与设置在用于盘位置检测的印刷电路板上的脉冲检测元件相关联。通过根据旋转部件的旋转对从脉冲检测元件获得的脉冲进行计数来检测托盘单元的移动位置。

摘要： First and second tape-pulling members comprise slanted posts and guide rollers adapted for engagement with the tape contained in a tape cassette. By the slanted posts and guide rollers, the first and second tape-pulling members pull the tape out of the tape cassette. Each of the guide rollers includes a tape-winding portion around which the tape is to be wound. First and second holding members are provided at positions where the tape loading by the first and second tape-pulling members is completed. Tape control portions, by which the tape disengaged from the guide rollers are controlled, are formed on the first and second holding members, respectively, such that they are located on the tape-outlet sides of the guide rollers of the first and second tape-pulling members, i.e., on the side closer to a cylinder. Each of the tape control portions is substantially at the same level as the corresponding tape-winding portions of the guide rollers.

摘要： A cassette tape slack-preventing apparatus to prevent magnetic tape from becoming slack when inserted into a video tape recorder in which the capstan motor drives the reel bases as well as the cassette loading machanism. Mode switching cams are used to detect if a front loading mechanism is in operating and keeps the reel bases from rotating through linkages to the cams.

摘要： A driving gear is attached to a capstan motor used for driving a capstan. The driving gear is rotated together with the capstan motor. A vertically-movable gear, which is movable in the axial direction thereof, faces the driving gear, and is designed in such a manner as to selectively mesh with the driving gear. The vertically-movable gear is moved up or down by a switch lever, and this switch lever is swung in accordance with the rotation of a mode-switching cam. When the vertically-movable gear is raised by the up swing of the switch lever and brought into mesh with the driving gear, a front loading mechanism moves a cassette holder which holds a tape cassette containing a magnetic tape, and loads the tape cassette in a tape-driving mechanism by utilization of the rotating force of the driving gear transmitted to the front loading mechanism through the vertically-movable gear. When the tape cassette has been loaded in the tape-driving mechanism, the switch lever moves down the vertically-movable gear in accordance with the rotation of the mode-switching cam, thereby disengaging the vertically-movable gear from the driving gear. In this manner, the operation of the front loading mechanism is stopped.
