ABSTRACT:
An electromagnetic release device in a camera having a power source for charging a capacitor, and an electromagnet for release connected between the terminals of the capacitor includes switch means for selectively connecting the capacitor to the power source or the electromagnet. The switch means is adapted to connect the capacitor to the electromagnet in response to shutter release operation to thereby form a discharging circuit for the capacitor and adapted, during the other time, to connect the capacitor to the power source to thereby form a charging circuit for the capacitor.
