Description
(54) УСТРОЙСТВО ДЛЯ УПРАВЛЕНИЯ ЛЕНТОПРОТЯЖНЫМ МЕХАНИЗМОМ АППАРАТА МАГНИТНОЙ ЗАПИСИ(54) DEVICE FOR CONTROLLING THE TAPE-MECHANISM MECHANISM OF THE MAGNETIC RECORDING DEVICE
При движении ленты в пр мом направлении сигнал с датчика 1 с соответствующим потенциалом поступает на схему сравнени и на дифференцирующую цепочку. При торможении движени ленты с коммутатора на другой вход схемы 2 поступает также разрещающее напр жение, а при переходе величины скорости через нулевую отметку напр жение на выходе датчика исчезает и перепад напр жени через цепочку 3 в виде короткого импульса приходит на другой вход коммутатора. ЛПМ останавливаетс . При перемотке ленты в обратном направлении и следующим за этим ее тор.можением имеет место несколько иной режим , но принципиально не отличающийс от указанного, т. е. торможение ленты осуществл етс в тот момент, когда она замедлила свое движение, что снижает динамические нагрузки .When the belt is moving in the forward direction, the signal from sensor 1 with the corresponding potential is fed to the comparison circuit and to the differentiating chain. When braking the tape from the switch to another input of circuit 2, the permitting voltage also flows, and when the speed passes through the zero mark, the voltage at the sensor output disappears and the voltage drop through the chain 3 in the form of a short pulse arrives at the other input of the switch. LPM stops. When the tape is rewound in the opposite direction and following its torus braking, a slightly different mode takes place, but it is not fundamentally different from the indicated one, i.e., the tape is braked at the moment when it slows down, which reduces the dynamic loads.
Учитыва высокую стоимость магнитной ленты, особенно примен емой дл видеозаписи, ее сохранность вл етс бузусловно необхоДИМОЙ . Описанное устройство позвол ет повысить срок эксплуатации магнитной ленты.Considering the high cost of a magnetic tape, especially used for video recording, its safety is certainly indispensable. The described device allows to increase the life of the magnetic tape.
