Abstract

The auto-wireless shutter release control is a mechanism that will allow the user to take a photograph by remote control. The system is comprised of an emitter that upon activating (push button) sends out a wave signal that is accepted via a receiver, which in turn activates a solenoid that pushes a cable plunger, releasing the camera shutter button, resulting in the photograph being taken.

Claims

1. An automatic wireless remote control device which employs a switching mechanism to control a camera or the like, comprising emitter means for emitting a signal, receiver means for receiving the emitted signal comprising a power source, a resistor connected to the power source a phototransistor connected to the resistor, and a series circuit consisting of a second transistor and a solenoid connected in parallel with said phototransistor, the base of said second transistor being connected to ground.

2. The automatic wireless remote control device according to claim 1 further including means for connecting said receiver means to a hot shoe of said camera.

3. The automatic wireless remote control device according to claim 1 wherein said emitter means comprises a power source, a current limiting diode and a switch all connected in series.
