ABSTRACT:
When a photographic camera is set to take a picture using a strobo, depression of a shutter release button of the camera is prevented until the charge stored in a capacitor for the strobo reaches a required level to flash a strobo discharge lamp. A shutter lock means includes a mechanical locking lever, an electromagnetic lock releasing means and a control circuit for controlling the electromagnetic lock releasing means. The mechanical locking lever is located at a lock position where it prevents depression of the shutter release button when the camera is set to take a picture using the strobo, and is held in the lock position until the electric charge stored in the capacitor reaches the required level by the attractive force of an electromagnet of the electromagnetic lock releasing means. When the charge has reached the required level, the electromagnet is deenergized and the mechanical locking lever is allowed to move to a release position by a spring force, whereby the depression of the shutter release button is allowed.
