A mode selection member is moved to the lowest position for selecting a
daylight mode, which is most frequently used, the middle position for
selecting a middle mode for photographing outdoors under the overcast
sky, or the highest position for selecting an indoor mode for
photographing indoors. When the mode selection lever is in the middle
position or the highest position, the upper end of a mode indicating
plate protrudes from a unit body. When the mode indicating plate is
pushed down into the unit body, the mode selection lever is forced to
return to the lowest position to set the daylight mode.
