Description
Изобретение может быть иснользовано дл намерени колебаний нат жени магнитной ленты в лентопрот жных ме.ханизма.ч точной магнитной зааиси.The invention may be used to intend fluctuations in the tension of a magnetic tape in a tape machine. Precise magnetic lock.
измерители нат жени ленты, содержащие упругий элемент с иcтoчии:кo света и фотодиодом. tape tension meters that contain an elastic element with the source: light and photodiode.
Недостатком известных устройств вл етс погрешность ;1змерени «ат жени ленты от неправильной устано-вк.и упругого элемента (стержн ) по отношению к продольной осн, т. е. установки его продольной оси под углом действующей силы, что вызы-вает наличие осевой силы, Ы:Зывающей погрешность измерени .A disadvantage of the known devices is the error; 1, measuring the belt tension from an incorrect installation and elastic element (rod) with respect to the longitudinal axis, i.e., installing its longitudinal axis at an angle of acting force, which causes an axial force , S: Irregular measurement error.
Дл повышени точности и универсальности измерени в предлагаемом устройстве упругий элемент выполнен в виде изогнутой коНСоли, свабодный конец которой размещен перед фотодиодом.To increase the accuracy and versatility of the measurement in the proposed device, the elastic element is designed as a curved co-salt, the free end of which is located in front of the photodiode.
На чертеже показано описываемое устройство .The drawing shows the described device.
На неподвижном основании / устройства, жестко закреплен упругий элемент 2, имитирующий головку записи-воопроиз-ведени . Магнитна лента 3 огибает элемент 2. ПередOn a fixed base / device, an elastic element 2 is rigidly fixed, imitating a recording-voproiz-head. Magnetic tape 3 goes around element 2. Before
щелью между упругим элeмeнтo 2 и бортом основани установлен светопровод 4 и система линз 5. За щелью устройства установлен фотодиод 6, который соединен с усилителем 7 и регистрирующ 1м устройством 5.a light guide 4 and a lens system 5 are installed in the gap between the elastic element 2 and the base of the device. A photodiode 6 is installed behind the device slot, which is connected to the amplifier 7 and registering 1 meter device 5.
Предлагаемое устройство работает гледуюидиМ образом.The proposed device works the same way.
При ДБиженнн магнитной ленты 3 (со скоростью Vo), огибающей упругий элемент 2, равнодер1ствующие сил 5i и S2 ветвей магнитной ленты 3 деформируют упругий элемент 2 и измен ют щель между элементом 2 и бортом основани /, тем самым измен етс и световой ноток светопроводом 4, системой линз 5 и фотодиодом 6. Сигнал изменени нат жени ленты 3 попадает в усилитель 7 и регистрирующий прибор 8.When DBIENNA magnetic tape 3 (with the speed of Vo), the envelope of the elastic element 2, equal-forming forces 5i and S2 of the branches of the magnetic tape 3 deform the elastic element 2 and change the gap between the element 2 and the base of the base /, thereby changing the light and light guide 4 , the lens system 5 and the photodiode 6. The signal for changing the tension of the tape 3 enters the amplifier 7 and the recording device 8.
Предмет изобретени Subject invention
Из.меритель нат жени ленты, содержащий ушругий элемент с источником света и фотодиодом , отличающийс тем, что, с целью повышени точности и универсальности измерени , упругий элемент вьшолнен в виде лзогнутой .консоли, свободный конец которой размещен перед фотодиодом.A belt tension meter containing an other element with a light source and a photodiode, characterized in that, in order to increase the accuracy and versatility of the measurement, the elastic element is embodied in the form of a bent console, the free end of which is placed in front of the photodiode.
