摘要： A camera including a housing having a film compartment adapted to receive a film cartridge with a closure adapted to hold the film cartridge within the film compartment. The closure has a resilient finger movable therewith which is adapted to engage a projection on the surface of the film cartridge during movement of the closure to a closed position so that subsequent movement to an open position will initiate movement of the film cartridge out of the film compartment.

摘要： A preferably pocket-sized camera having an overall shape which is thin in its vertical dimension has its horizontal longitudinal dimension shortened by constructing the camera in two relatively horizontally telescoping sections. One of the camera sections is a main camera section including substantially all of the components of a still camera except for the viewfinder portion thereof. The other section of the camera has a housing which interfits with the housing of the main camera sections so in its retracted position the front and rear viewfinding lens elements thereof interleave with elements of the main camera housing. When the viewfinder section is in its extended position, the front and rear viewfinder lens elements are unobstructed. In the retracted position of the viewfinder section, a part thereof covers the objective lens and shutter release member in the main section of the camera, and wall elements of the main camera section cover over the viewfinder lens elements. The movable viewfinder carrying section is provided with means for cocking the shutter operating mechanism of the camera and removing a film perforation sensing finger as it is moved to its retracted position and means for effecting a film advancing operation when the viewfinder section is moved to its extended position.

摘要： A preferably pocket-sized camera adapted for underwater as well as above water use, comprises a one-piece outer housing formd of a transparent synthetic plastic material having most areas thereof coated with an opaque material except for areas forming objective lens and viewfinder window means, and, when used, electronic flash light diffusing window means, to eliminate the need for waterproofing these areas of the camera. The housing has an opening at the rear thereof providing an entry into a compartment for receiving a camera mechanism support frame on which are mounted substantially all of the functional components of the camera. Openings formed in the housing receive in watertight relation shutter, film advancing means, and, when used, electronic flash setting means. A closure member, having means thereon which cooperates with releasable closure sealing and locking means on the main housing, is provided for the opening in the rear of the housng.

摘要： A unique percussive flash unit includes an initially cocked striker and flash unit rotating assembly, which includes a main member with an inclined laterally projecting cam-forming wall having an inclined cam face which engages and cams outwardly a lateral extension of an actuator and striker holding member to operate a percussive flash unit when the cocked striker and flash unit rotating assembly is released by operation of a shutter release member. The actuator and striker holding member then returns to its initial position, and when the striker and flash unit rotating assembly is cocked during a shutter resetting operation, the lateral extension of the actuator and striker holding member is moved out of the way of the cam-forming wall by the engagement with the member of a portion of the flash unit socket as it is rotated by a portion of the striker and flash unit rotating assembly so the cam-forming wall will not strike the lateral extension. The actuator and striker holding member includes a shoulder which prevents the movement of the striker and flash unit rotating assembly from its cocked to its uncocked position when a flash unit is not mounted upon the camera.
