Description

подает сигнал на электронный коммутатор 9, переключающий вход блока 1О записи с источника 7 звукового сигнала на источник 8 сигнала сенситометрической пробы . После записи сенситометрической пробы блок 6 управлени  вновь подключает вход блока 1О записи к источнику 7 звукового сигнала. Повторное срабатывание электронного коммутатора 9 при случайном нажатии кнопки 2 оператором исключено благодар  наличию цепи блокировки, соедин ют ей блок 10 зшшси н блокирук ший узел 4. Включение последнего возмо но лишь при зар дке нового рулона киноленты в блок 10 записи.sends a signal to the electronic switch 9, which switches the input of the 1O recording unit from the source 7 of the sound signal to the source 8 of the signal of the sensitometric test. After recording the sensitometric test, the control unit 6 again connects the input of the recording unit 1O to the audio source 7. Repeated operation of the electronic switch 9 by accidentally pressing button 2 by the operator is excluded due to the presence of a blocking circuit, it is connected to block 10 of blocking and blocking node 4. The latter can only be turned on when charging a new film reel into block 10 of recording.

Предмет изобретени Subject invention

Устройство дл  записи с нситометричсг ких проб на киноленту, содержащее кнопку включени  записи, блокирующий узел, св занный с блоком задержки и электронный коммутатор, подключенный к блоку записи и источникам сигналов, отличаюш е е с   тем, что, с целью исключени  ошибок оператора, в него введены избирательный усилитель, соединенный с блокирукщим узлом и с кнопкой записи, и блок управлени , св занный с блоком задержки и электронным коммутатором, причем блокирукддий узел подключен к блоку записи. IA device for recording nitsitometric samples on a film, containing a record enable button, a blocking node associated with a delay unit, and an electronic switch connected to the recording unit and signal sources, which, in order to eliminate operator errors, it has a selective amplifier connected to the blocking node and a record button, and a control unit connected to the delay unit and an electronic switch, with the blocking node being connected to the recording unit.
