An exposure indicating device for use in a multiple exposure control camera is capable of indicating the diaphragm aperture value and the shutter speed which are to be effected, respectively. With the diaphragm aperture value manually set, and with the shutter speed automatically controlled, the shutter speed to be effected by a control circuit is indicated by a meter pointer and a shutter speed scale member. With the shutter speed manually selected and the diaphragm aperture value automatically controlled, an aperture value indicating member includes an indicating portion and is movable relative to the shutter-speed scale member to indicate the manually set shutter speed indicating portion, and the diaphragm aperture value to be automatically controlled is indicated by a meter pointer on the aperture value indicating member.
