摘要： A magnetic tape drive (20) employs trolleys (40) for moving magnetic tape between a tape retracted position and a tape extracted position. A trolley position sensor (104, 106) generates a trolley position signal: A processor (100) uses the trolley position signal to control a supply reel motor (30), and thereby prevent slack in tape during a retraction operation. The processor (100) uses the trolley position signal to determine a supply reel motor reference position signal, and then uses a difference between the supply reel motor reference position signal and the supply reel motor position signal to control the supply reel motor (30).

摘要： An improved clutch device for transmitting the motive power from an associated follower pulley to a selected reel support via an associated idler gear in a videotape recorder. It comprises a top clutch fixed to the top of the axle of the follower pulley, and a coupling gear urged by an associated coiled spring apart from the top clutch and fitted around the top clutch. The top. clutch has a plurality of nail pieces integrally connected to and descending from its circumference. Each nail piece has two ramp-shaped indents formed on its opposite sides. The coupling gear has rib pieces integrally connected to and descending from its circumference. Each rib piece has a counter ramp-shaped indent inside, thereby allowing one or the other ramp-shaped indent of each nail piece to engage with the counter ramp-shaped indent of each rib piece while the top clutch is made to descend in the annular space of the coupling gear, thus preventing further descent of said top clutch.

摘要： An idler device of the magnetic recording/reproducing apparatus is disclosed having the construction that an idler arm is inserted to the side of a clutch shaft which is installed at a lower surface of a main chassis. Without an extra construction for the assembly, a snap engagement is possibly made, so that a workability of an assembly working is improved and the number of parts can be reduced, and thus, a production cost can be reduced. In addition, the assembly of an idler gear is completed as a plate spring is fixed to an idler shaft in a state that the idler gear is inserted in the idler shaft of an idler arm. Thus, the assembly working is relatively facilitated, and a production cost can be reduced with the simple construction. Moreover, since the plate spring is installed in a state of being fixed at the protrusion bar by the stopper, the relative position of the plate spring is precisely set with respect to the neighboring parts, so that an operation reliability can be remarkably improved.
摘要翻译：公开了一种磁记录/再现装置的惰轮装置，其具有将惰轮插入到安装在主底盘的下表面的离合器轴侧的结构。没有组件的额外结构，可能进行卡扣接合，从而提高了组装工作的可加工性，并且可以减少部件的数量，从而可以降低生产成本。此外，当空转齿轮插入到惰轮的空转轴中的状态下，平板弹簧固定在惰轮上，完成空转齿轮的组装。因此，组装工作相对便利，并且通过简单的结构可以降低生产成本。此外，由于板簧通过止动件被固定在突出杆上的状态，所以板簧的相对位置相对于相邻部分精确地设定，从而可以显着提高操作可靠性。

摘要： A reel braking apparatus for a tape recorder selectively brakes a reel disk assembly, which includes a reel disk and a reel gear installed on a deck, according to an operational mode. The apparatus includes a clutch member supported by a rotation shaft installed on the deck, a gear member installed coaxially relative to the clutch member so as to rotate by being engaged with the reel gear, and a clutch spring installed between the gear member and the clutch member for restricting rotation of the gear member so that the gear member can rotate in one direction according to a rotational direction of the reel gear. The clutch member and the clutch spring are coupled to each other, and this allows the gear member installed for engagement with the reel gear of the reel disk assembly to rotate in one direction only. Thus, as soon as the rotation of the gear member changes according to a change in rotation direction of the reel gear from a forward direction to a reverse direction, the rotation of the gear member is restricted by the clutch spring, and rotation of the reel gear is stopped.
摘要翻译：根据操作模式，用于磁带录音机的卷轴制动装置根据操作模式选择性地制动卷轴盘组件，其包括安装在甲板上的卷轴盘和卷轴齿轮。该装置包括由安装在甲板上的旋转轴支撑的离合器构件，与离合器构件同轴安装的齿轮构件，以便通过与卷轴齿轮啮合而旋转;以及离合器弹簧，其安装在齿轮构件和离合器之间用于限制齿轮构件的旋转的构件，使得齿轮构件可以根据卷轴齿轮的旋转方向在一个方向上旋转。离合器构件和离合器弹簧彼此联接，并且这允许安装用于与卷轴盘组件的卷轴齿轮接合的齿轮部件仅在一个方向上旋转。因此，一旦齿轮构件的旋转根据卷轴齿轮的旋转方向从正向改变到相反方向，齿轮构件的旋转被离合器弹簧限制，并且卷轴的旋转齿轮停止

摘要： Disclosed is an improved friction type of power transmission mechanism for driving a reel support in a VTR wherein the power is transmitted from the motor to the reel support via the follower pulley, which is sandwiched and clamped between a base disk and an annular plate. The follower pulley has a first friction ring sandwiched between the base disk and the lower flange surface of the follower pulley and a second friction ring sandwiched between the annular plate and the upper flange surface of the follower pulley. With this arrangement an increased torque can be produced without causing excessive abrasion. The diameter of the circular opening of one of the first and second friction rings is equal to or larger than the outer diameter of the other friction ring. This has the effect of saving the material of friction ring.
