摘要： A CAMERA CONSTRUCTION OF THE TYPE EMPLOYING FILM USUALLY CONTAINED IN A CARTRIDGE AND HAVING PERFORATIONS ALONG ITS LENGTH FOR PROVIDING FRAME-BY-FRAME INDEXING. THE SENSING FINGER IS PROVIDED FOR ENGAGEMENT WITH THE RESPECTIVE PERFORATIONS, AND UPON ENGAGEMENT, THE FILM WINDING MEANS IS LOCKED. THE CAMERA SHUTTER IS UNLOCKED TO PERMIT TAKING OF A PICTURE, AND THE PICTURE TAKING ACTION OPERATES TO DISENGAGE THE FINGER FROM A FILM PERFORATION TO PROVIDE FOR INDEXING MOVEMENT. THE SHUTTER ACTUATING MEMBER IS DIRECTLY TIED TO A FIRST PIVOTING MEMBER WHICH MOVES A SECOND PIVOTING MEMBER, THE LATTER DIRECTLY CONTROLLING BOTH THE FINGER AND FILM ADVANCE LOCKING MEANS SO THAT THE MOVEMENTS OF THESE ELEMENTS ARE DIRECTLY DEPENDENT UPON EACH OTHER.

摘要： A flash lamp actuating structure for a camera having means for holding a length of film, film advancing means, and a shutter means for exposing successive frames of film. The shutter means includes at least one movable plate having an opening for registering with a camera lens opening when the plate is moved during shutter operation. A flash bulb of the type which will operate in response to impact imparted by a spring loaded finger is adapted to flash in the course of film exposure. The spring loaded finger is engaged for impact movement by a push bar which is normally retained against movement. During an initial stage of shutter actuation, a spring means is wound whereby energy is stored in the spring means. A push bar actuating member is adapted to be operated by this spring means, and this operation occurs at a later stage of the shutter actuation when the means for retaining the push bar is moved out of the way. The spring energy is released rapidly whereby the push bar will be driven with sufficient force and speed into engagement with the flash lamp impact finger. The push bar also defines means for engaging the shutter plate whereby the film exposure is dependent upon the movement of the push bar.

摘要翻译： 一种用于照相机的闪光灯致动结构，具有用于保持一定长度的胶片，胶片推进装置和用于曝光连续胶卷的快门装置的装置。 快门装置包括至少一个活动板，当板在快门操作期间移动时，其具有用于与相机透镜开口配准的开口。 这种类型的闪光灯会响应由弹簧加载的手指所施加的冲击来操作，适于在胶片曝光过程中闪光。 弹簧加载的手指通过通常保持抵抗运动的推杆而被接合用于冲击运动。 在快门致动的初始阶段期间，卷绕弹簧装置，从而将能量存储在弹簧装置中。 推杆致动构件适于由该弹簧装置操作，并且当用于保持推杆的装置移动时，该操作在快门致动的稍后阶段发生。 弹簧能量被快速释放，由此推杆将以足够的力和速度被驱动与闪光灯冲击指状物接合。 推杆还限定用于接合挡板的装置，由此胶片曝光取决于推杆的移动。

摘要： A camera construction including a housing holding a length of film and having film-advancing means and a shutter means for exposing successive frames of film. The shutter means consists of movable plates with an opening defined by one plate for registering with a camera lens opening. A flashbulb of the type which will operate in response to impact from a spring-loaded finger is adapted to flash immediately prior to film exposure. The spring-loaded finger of the flashbulb is operated in timed relationship with the film exposure by means of a push bar which engages the finger in response to engagement of the bar by the movable shutter plates.
