Remote control shutter device for a camera

Claim 1

A shutter device comprising a housing supported above a camera by a support, a motor and a reduction gearing disposed in said housing, said reduction gearing being engaged with said motor and being driven by said motor, a rack movably disposed in said housing and engaged with said reduction gearing so that said rack can be driven to move up and down by said motor, a lower portion of said rack being extendible downward beyond said housing, a rod integrally formed on said lower portion of said rack and located above a shutter release button of said camera, a lever formed on one side portion of said rack, a first conductor slidably disposed on said lower portion of said rack, a notch formed in an upper portion of said first conductor so that an ear is formed above said notch, a portion of said lever being engaged in said notch, a second conductor fixed on said rack and having a lug extended therefrom, said lug being disposed upon said portion of said lever, a sleeve coupled to a lower end of said first conductor and having a recess formed in a bottom thereof, a lower end of said rod extendible downward beyond said first conductor and extendible into said recess of said sleeve, a spring biased between said rack and said first conductor for biasing said first conductor downward relative to said rack so that said lug of said second conductor is caused to contact with said ear of said first conductor, a switch disposed in said housing and can be actuated by said lever; said sleeve being caused to depress said shutter release button when said rack is driven to move downward by said motor, said first conductor and said sleeve being caused to move upward relative to said rack against said spring when said shutter release button is depressed so that said ear of said first conductor is caused to be separated from said lug of said second conductor, said motor being caused to move in a reverse direction when said ear of said first conductor is separated from said lug of said second conductor so that said rack can be driven to move upward by said motor, and said motor being stopped when said switch is actuated by said lever.
