ABSTRACT:
A camera protects against wasting battery power by turning off an illuminating device when a photographer is engaged in an photographic operation. The illuminating device includes a back light which illuminates a displace device for display of information related to photography and a release actuation member which generates a half press signal and a full press signal, respectively, upon a first and a second stroke. The back light is turned on according to a "turn on" signal, while the back light is turned off according to the half press signal. The back light is also turned on when the photometric value of a photometric circuit is above a predetermined value.
