Abstract
A power supply unit shared by a camera's motor drive and an electronic flash comprises a timing circuit which becomes operative at the termination of a shutter release operation, or a detector which detects the energization of a motor contained in the motor drive. Either timing circuit or detector operates to feed the motor drive or the electronic flash in alternate fashion in time so as to prevent both the motor drive and the electronic flash from being simultaneously fed from a single common d.c. source.
