Description

Изобретение относитс  к фототехнике, а «менно к фотоаппаратам, в которых транспортирование пленки и взвод фотозатвора осуществл ютс  пружинным двигателем, поэе1зол ющим производить фотосъемку с высокой частотой .The invention relates to photographic equipment, and, in particular, to cameras in which film transport and photo shutter cocking are carried out by a spring motor, which makes it possible to take photographs at a high frequency.

Известны механизмы транспортировани  пленки, в которых транспортирование пленки И взвод фотозатвора осуществл ютс  пружинным двигателем, взаимодействующий с приемным барабаном {1}.The mechanisms for transporting the film are known, in which the transport of the film and the cocking of the photogate is carried out by a spring motor interacting with the receiving drum {1}.

Однако в этом устройстве возможны сдвиг пленки во врем  спуска фотозатвора нри разблокировании механизма пружинного двигател  и блокирование, траиспортировани  механизмом спуска фотозатвора.However, in this device, film shear is possible during the release of the photo shutter by unlocking the spring motor mechanism and blocking, transporting the photo shutter by the release mechanism.

Кроме того, при транспортировании пленка передвигаетс  неравномерно от кадра к кадру, так как в процессе съема увеличиваетс  диаметр рулона пленки на приемном барабане.In addition, during transport, the film moves non-uniformly from frame to frame, as the diameter of the film roll on the receiving drum increases during the removal process.

Все это снижает качество получаемых снимков .All this reduces the quality of the resulting images.

В известном механизме транспортировани  пленки транспортирующие звездочки выполн ютс  с неполным числом зубьев и в момент срабатывани  затвора пленка расцепл етс  с мерным валиком, постепенно останавлива сь.In the known transport mechanism of the film, the transporting sprockets are made with an incomplete number of teeth and at the moment of the shutter release the film disengages from the measuring roller, gradually stopping.

так как имеющийс  8 кинематической схеме фрикцион подматывает пленку {2.since there are 8 kinematic schemes, the friction clutches the film {2.

Таким образом, возможность сдвига пленки в момент экспонировани  в этом устройстве 5 не исключаетс .Thus, the possibility of film shear at the time of exposure in this device 5 is not excluded.

Цель изобретени  - обеспечение равномерности транспортировани  и исключение ее сдвига во врем  экспонировани .The purpose of the invention is to ensure uniform transportation and exclude its shift during the exposure.

Указанна  цель достигаетс  введением а 10 кинематическую цепь механизма транспортировани  пленки двуплечего рычага, одно плечо которого контактирует с упором, закрепленным на оси приводного двигател , а другое плечо кинематически св зано с поворотным подпружиненным рычагом, установленным с S возможностью возвратно-поступательного перемещени , и взаимодействующим с кулачком мерного валика.This goal is achieved by introducing a 10 a kinematic chain of the transport mechanism of the two-arm lever, one arm of which is in contact with the stop fixed on the axis of the drive motor, and the other arm is kinematically connected with a rotatable spring-loaded lever installed with S possibility of reciprocating movement and interacting with cam measuring roller.

На чертеже представлена кинематическа  схема механизма транспортировани  пленки.The drawing shows a kinematic diagram of the film transport mechanism.

Пружинный двигатель кинематически св зан с осью 2, на которой расположена niecTepда 3 с упором 4 и фрикциЬнно закреплена приемна  катушка 5. На оси зубчатого барабана 6 расположена шестерн  7 с кулачком 8, котора  находитс  в зацеплении с шестерней 3. Кулачок 8 взаимодействует с приводной рейThe spring motor is kinematically connected with the axis 2, on which niecTerda 3 is located with an emphasis 4 and the receiving coil 5 is fixedly frictionally attached. On the axis of the gear drum 6 there is a gear 7 with a cam 8 which is in engagement with the gear 3. The cam 8 interacts with the drive shaft
