A recyclable single-use camera in which a front casing portion is separable from a main body portion to replace a taking lens during recycling of said camera, is characterized in that the taking lens has a front lens element and a rear lens element. The rear lens element is secured to the main body portion in order to prevent removal of the rear lens element. The front casing portion holds the front lens element in optical alignment with the rear lens element, and permits removal of the front lens element to allow it to be replaced whenever the front casing portion is separated from the main body portion during recycling of the camera.

Photographic film loading method and apparatus and a camera frame assembly having an internally baffled supply chamber. In the method, a guide is interposed in the chamber and a leading portion of the filmstrip is transported into the chamber. The filmstrip is then coiled within the chamber, between the guide and the baffle to form a film roll. During the coiling, an internal diameter of the film roll is maintained constant. The guide is withdrawn and the baffle is retained within the chamber with the film roll.
摘要:
An apparatus and method for loading and prewinding a photographic film cartridge in a camera frame assembly. The camera frame assembly has a rear opening. The camera frame assembly has a cartridge chamber and a supply chamber facing the rear opening. In the method, a film cartridge is first positioned in the cartridge chamber of the camera frame assembly. The leading portion of a filmstrip is advanced out of the cartridge to the supply chamber of the camera frame assembly. A mandrel is admitted into the supply chamber. The leading portion of the filmstrip is guided around the mandel. The filmstrip is cinched to the mandrel. The mandrel is rotated to wind a main portion of the filmstrip into a film roll around the mandrel. The mandrel is removed from the film roll. The rear opening of the camera frame assembly is closed.

A camera comprises a shutter-flash synchronization contact, a pair of battery contacts, a flash capacitor, and a flash circuit board conductively connected to the shutter-flash synchronization contact, the pair of battery contacts and the flash capacitor. A holder which holds the flash capacitor is conductively connected to the flash circuit board and is integrally united with the shutter-flash synchronization contact and the pair of battery contacts to conductively connect the shutter-flash synchronization contact and the battery contacts to the flash circuit board. As a result, the camera can be made relatively compact.

A camera comprises a film winding knob manually rotatable to rotate a spool to wind a filmstrip onto the spool, a clutching mechanism located between the film winding knob and the spool for allowing the film winding knob to be manually rotated without rotating the spool, and a shutter release button manually depressible to initiate picture-taking. The clutching mechanism includes a clutch component supported to be depressed to initiate picture-taking responsive to manual depression of the shutter release button.
摘要:
An assembly which can be used as a rotor in an electromagnetic actuator for a camera shutter. The assembly generally includes at least two pieces of magnetic material each having a north and south pole, a drive arm, means for magnetically holding the magnetic material in a fixed position relative to the drive arm and means for rotating the assembly within the electromagnetic actuator. In one embodiment of the invention, the magnetic material comprises a first magnet and a second magnet. Preferably, the first magnet and the second magnet are rectangularly shaped.
