Description

цвухпоэициониым переключателем 3 пол рности .3 pole polarization switch.

В зависимости от пол рности зар дки различные фотопоп5гпроводийковыв носители j записи зар жаютс  до различной величины начального потенциала, начального потенциала селеновых слоев выше при полоиштельном коронном зар де, нежели при отрицательном. Дл  выравнивани  начальногЬ ю потенциала сло  в зависимости от зар дки предусмотрен переключатель 5 (см, фиг. 1), мен гсоций рабочее напр жение коронного зар  аника 1 в зависимости от положени  двухпозиционного переключател  3 пол рнос1гЦз (увеличива  или уменьша  его).Depending on the polarity of the charge, various photocopic conductors in the record carrier j are charged to a different initial potential, the initial potential of the selenium layers is higher with a full corona charge than with a negative one. To equalize the initial potential of the layer depending on the charge, switch 5 is provided (see Fig. 1), mentions the working voltage of the corona charge 1 depending on the position of the two-way switch 3 polnczz (increasing or decreasing it).

Другой вариант вьтолнени  устройства (см, фиг. 2) дредпопагает изменение напр жени , подаваемого на экран 6 зар дника 1 с помощью выключател  7, св занного 20 с двухпозиционным переключателем пол рности 3, и сопротивлений 8,Another embodiment of the device (see Fig. 2) prevents the change in voltage supplied to the screen 6 of charger 1 by means of a switch 7 connected 20 to a two-way switch of polarity 3, and resistances 8,

При изменении пол рности с помощью авухпозиционного переключател  3 переключатель 9 включает сопротивление 10, 25 измен ющее напр жение питани  источника освещени  11, уменьша  или увеличива  .его ;интенсивность,JWhen the polarity is changed by means of an avuhpozionnogo switch 3, the switch 9 switches on the resistance 10, 25 changing the supply voltage of the light source 11, reducing or increasing it; intensity, J

Изменение интенсивности освещени  достигаетс  за счет введени  серых светофильтров 12 (.см. фиг, 4) в зависимости от пол рности зар дки.A change in the intensity of illumination is achieved by introducing gray light filters 12 (see Fig. 4) depending on the polarity of the charge.

Таким образом, предлагаемое зараавое устройство позвол ет зар жать слой Kak прло тельным, так и отрипательным зар адм что позвол ет, получать копии и с негативных , и с позитивных оригиналов, позитивные копии без смены пройвл кидего состава.Thus, the proposed device allows you to charge the layer Kak with both positive and negative charge, which allows you to get copies of both negative and positive originals, positive copies without changing the type of projev film.
