Abstract
A camera may contain a plurality of operable elements such as small motors for actuating mechanisms such as a mirror, shutter, diaphragm, film, transport, etc., supplied with power from a self-contained battery. Because of the low power of the battery certain of the operable elements are actuated sequentially whereas parallel operation thereof would be preferable. The present invention provides circuitry which automatically changes the sequential operation of the elements to parallel operation whenever the self-contained source of power is replaced by an external power source.
