The electronic image recording portion includes an operation changing circuit for making an alternate change between a recordable state and an image recording state according to a signal output by the medical photographic portion and a strobe synchronous circuit for outputting a strobe synchronizing signal according to which a strobe emits a flash of light when the recordable state is changed to the image recording state. The display selecting circuit makes an alternate change between the state in which the observation image is displayed and the state in which the record image is displayed in accordance with the signal output by the medical photographic portion.
