摘要： In a video tape recorder (VTR) (2), the capstan (10) draws the tape (6) from which the video signal is reproduced in a forward direction. Following steps are proposed to control the capstan (10):

applying a torque to the capstan (10) in a backward direction for a first predetermined period of time ;
applying a torque to the capstan (10) in the forward direction for a second predetermined period of time ;
nullifying the motor current.

This is particularly convenient for slow-motion and still-picture reproduction modes.

摘要： The invention is concerned with a magnetic recording/playback apparatus in which a magnetic tape is paid out from a tape cassette and wound around a cylindrical rotary head cylinder, having a rotary head built therein, over a predetermined angle to record/playback signals through the rotary head, and more particularly, with a tape guide post driving mechanism, a pinch roller pressing mechanism and a tension servo mechanism. Specifically, the invention provides a tape guide post driving device which can reduce the size, weight and thickness of the apparatus by ensuring a large angle of rotation of a rotating member, which includes a tension arm, in a direct manner. Also, the invention realizes a pinch roller pressing mechanism in which a sufficient stroke can be obtained even when a cam gear is reduced in its diameter and can provide a sufficient stroke even with a small amount of rotation. Further, the invention prolongs the service life and achieves a remarkable reduction in both the number of parts used and the number of assembling steps by using a pad brake (brake member), instead of a band brake, for braking a rotating member and bringing the brake member into full contact over the former's entire surface with the member being braked.
摘要翻译：本发明涉及一种磁记录/重放装置，其中从磁带盒中取出磁带，并将其内置旋转磁头的圆柱形旋转磁头磁鼓卷绕在预定角度上，以便记录/重放信号旋转头，更具体地，具有带引导柱驱动机构，夹送辊压机构和张力伺服机构。具体地说，本发明提供一种带引导柱驱动装置，通过以直接的方式确保包括张力臂的旋转构件的大的旋转角度，能够减小装置的尺寸，重量和厚度。此外，本发明实现了一种夹送辊压机构，其中即使当凸轮齿轮的直径减小时也能获得足够的行程，并且即使在少量旋转的情况下也能够提供足够的行程。此外，本发明延长了使用寿命，并且通过使用垫制动器（制动构件）而不是带式制动器来实现使用的部件数量和组装步骤的数量的显着减少，以制动旋转构件并使制动构件在制动器的整个表面上完全接触。

摘要： A reel braking mechanism for each reel table (210, 220) in a mechanism for controlling the distance between reel tables to selectively place tape cassettes thereon is provided. The reel braking mechanism has reel tables (210, 220), rotating arms (211, 221) supporting brake members (260, 270), a rotating apparatus for rotating the rotating arms (211, 221), and moving members (284, 294) for moving the brake members (260, 270). Therefore, the brake members (260, 270) rotated by the movement of the moving members (284, 294) can be released from the reel tables (210, 220).

摘要： A video tape recorder has a tape tensioning mechanism (61) for tensioning a magnetic tape (6) drawn out of a tape cassette (2). The tape tensioning mechanism has a tensioning arm (56) angularly movably mounted on a movable chassis (16) with a tensioning pin (57) for contacting the tape to tension the tape when the tape has been loaded in a predetermined tape path, a tightening lever (65) movably mounted on the movable chassis, and a tension spring (68) for normally urging the tensioning arm in a direction to turn the tensioning arm to bring the tensioning pin into contact with the tape. A pusher (72) is fixedly mounted on a fixed chassis (14) for pushing the tightening lever to tighten the tension spring substantially at the same time that the magnetic tape is loaded in the predetermined tape path. When the magnetic tape is not loaded in the tape path, the tightening lever is released from the pusher to loosen the tension spring. Since the tension spring is not required to bias the tensioning arm when the magnetic tape is unloaded and is only required to bias the tensioning arm when the magnetic tape is loaded, the tension spring may be of a relatively small size.
摘要翻译：录像机具有用于张紧从磁带盒（2）拉出的磁带（6）的磁带张紧机构（61）。带张紧机构具有张紧臂（56），其可角度地可移动地安装在具有张紧销（57）的张紧销（57）上，用于在带已经被装载在预定的带路径中时接合带以张紧带，紧固可移动地安装在可移动底盘上的杆（65）以及用于在使张紧臂转动使张紧销与带接触的方向上正常地推动张紧臂的拉力弹簧（68）。推动器（72）固定地安装在固定底盘（14）上，用于按压紧固杆以基本上将磁带装载在预定的磁带路径中的同时紧固拉伸弹簧。当磁带未装载在磁带路径中时，紧固杆从推动器释放以松开张力弹簧。由于当磁带被卸载时拉伸弹簧不需要偏压张紧臂，并且仅当加载磁带时才需要将张紧臂偏压，所以拉伸弹簧可以具有相对较小的尺寸。

摘要： According to a magnetic tape high-speed braking apparatus, a cam groove (72) for setting various operation modes is formed in a cam gear (12). A high-speed mode such as a high-speed search is set on the cam gear (12) at that portion thereof which corresponds to an end portion of a loading state. When a loading motor (14) rotates in a predetermined loading direction, a worm gear (26a) is rotated in a first direction via pulleys (16, 20), a belt (18) and gears (20, 24). In high-speed search mode, a cam pin (30) of a cam lever (28) engaged with the cam gear (12) is fixed to a recess (62a) of a rotatable lock lever (62). When a tape end is detected and the cam gear (12) rotates in a direction opposite to the first direction, the cam pin (30) is separated from the recess (62a) by a projection (26c) of worm gear member (26), a lock release lever (64) and a spring (68). Accordingly, the cam lever (28), a brake connector (36), a brake switching lever (40) and a brake slider (42) are actuated to press brake shoes (46b, 48b) of main brakes (46, 48) abutting on the brake slider (42), against a feed reel stand (52a) and a take-up reel stand (52b), thereby instantaneously braking these reel stands.
