ABSTRACT:
An autowinder for use with all weather or underwater cameras includes a sealed generally U-shaped housing having a threaded attachment to a camera body. An internal power source and bidirectional motor are supported within the housing and operatively coupled to the film advance mechanism of the camera by a drive belt system. A generally L-shaped lever is pivotally supported upon the autowinder body exterior and is operated in response to a trigger to actuate the shutter mechanism of the camera. A magnet is supported upon the L-shaped trigger arm and actuates the autowinder function within the housing. Magnetic limit switches are operative to control the direction and extent of motor operation to provide appropriate autowinding action.
