ABSTRACT:
In an electromagnetic releasing device for exciting a release magnet for a predetermined time after depression of a release button to thereby elect shutter release, there is provided a circuit which generates, in response to the depression of the release button, a signal whose time width is short independently of the depression time of the release button. The excitation of the release magnet is initiated by the signal from said circuit. With this circuit, one depression of the release button results in only one releasing operation.
