Abstract: PURPOSE:To make it possible to easily and rapidly load and unload a magnetic tape without damaging this magnetic tape. CONSTITUTION:This brake mechanism is provided with a pendulum gear 20 which oscillates and drives one reel turntable by meshing therewith between a feed reel turntable 4 freely rotatably supported on a moving chassis 2B and a takeup reel turntable. A brake lever 30 which applies the brake to the take-up reel turntable side at the time of loading the magnetic tape around a rotary head drum provided at a stationary chassis 2A is freely rotatably and slidably supported with respect to the moving chassis 2B. This brake lever 30 is provided with a rack part 30d which meshes and parts with and from the tooth part 45c of a limiter gear 45 of the feed reel turntable 4. A stopper arm 33 which holds the meshing state of the rack part 30d of the brake lever 30 and the tooth part 40c of the feed reel turntable 4 are freely rotatably supported on the moving chassis 2B.

Abstract: PURPOSE:To resolve the problem of abrasion of a guide base lock surface at the time of moving a guide base of the tape loading mechanism and to enable a guide pole in a loading completion position to be under the state of its accurate posture. CONSTITUTION:A tape is loaded and unloaded onto and from a rotary head drum by making the guide base 10 erected with guide posts 6 and 8 movable along a guide groove 14 on a chassis by a loading arm. Sliding guide parts 19 are provided to be projectively upheaved higher than the lock surface 16 of the guide base 10 on both of right and left side peripheral parts of the guide groove 14, and the guide base 10 is moved in sliding with its back surface on these sliding guide parts 19.

Abstract: PURPOSE:To reduce the load exerted on a tape at the tape rewinding time and to reduce the electric power consumption of a reel motor, etc. by rotating a rotary drum in the reverse direction to recording and reproducing times with winding the tape on the rotary drum. CONSTITUTION:When a rewinding switch 1 is pushed, a drum motor 4 is reversed by switching the driving circuit 3 of a rotary drum by the controller 2 of a microcomputer, etc. The rewinding travel of the tape is started at about the same time or just before the start of the reversal of the drum motor 4. The rotary drum is reversed at about several times or 30 times speed compared to recording and reproducing times. The load exerted on the tape is thus reduced drastically, the tape damage accompanied by the tape traveling is also reduced and the electric power consumption of a reel motor, etc. for driving the tape traveling is reduced as well.

Abstract: PURPOSE: To use parts in common between supply and take-up reel drive disks by attaching a yoke plate to the opposite side of a magnet set opposite to a hiss plate of either one of both reel drive disks and giving different torques to both drive disks.
CONSTITUTION: The gear of a drive mechanism engages the tooth 2A of a lower reel drive disk 2 or a gear 6 and revolves at a take-up reel drive disk T. Thus the disk T also revolves. When the drive gear 6 is revolved, a magnetic flux generated from the other side of a magnet 3 is sent back to a magnet 3 through a yoke 11 since this yoke 11 is attached to the magnet 3. In this case, the density of the magnetic flux is higher than the disk T having no yoke plate 11. Then the revolving torque of the disk T is larger than that of a supply reel drive disk. Thus different torques can give to the supply and take-up reel drive disks although both disks have almost the same structure. Therefore the components parts can be used in common to both drive disks. This attains the reduction of cost.

Abstract translation: 目的：通过将轭板安装在与两个卷轴驱动盘中的任一个的咔嗒板相对的磁铁组的相对侧，并且向两个驱动盘提供不同的转矩，以便在供应和卷带盘驱动盘之间使用共同的部件 。 构成：驱动机构的齿轮与下卷轴驱动盘2或齿轮6的齿2A接合，并且在卷带盘驱动盘T上旋转。因此，盘T也旋转。 当驱动齿轮6旋转时，从磁体3的另一侧产生的磁通量通过磁轭11被送回到磁体3，因为该磁轭11被安装在磁体3上。在这种情况下， 磁通量高于没有轭板11的磁盘T.因此，磁盘T的旋转扭矩大于供带盘驱动盘的转矩。 因此，尽管两个盘具有几乎相同的结构，但是不同的扭矩可以给予供应和卷取驱动盘。 因此，组件部件可以共同用于驱动盘。 这样可以降低成本。

Abstract: PURPOSE:To miniaturize a driving device and, at the same time, a whole device by installing a differential gear device driven by a motor, loading ring driven from one of the output axis of a differential gear, and so forth. CONSTITUTION:A tape cassette 1 is mounted on a supply reel table 4 and a winding reel table 5 under the guidance of locating pins 2 and 3. A differential gear device 6 is driven from a loading motor through a reduction gear. One of the output shafts of the reduction gear is coupled with a ring gear driving gear 8 which is engaged with the ring gear of a loading ring 7 and the other output shaft is coupled with a cam wheel 9. When such a constitution is used, the driving device can be miniaturized and, at the same time, the whole device can be miniaturized.
