Zusammenfassung: | PROBLEM TO BE SOLVED: To minimize the imaging delay time of a fundus camera and the disappearance time of a finder without limiting the types of digital single-lens reflex cameras to be connected. SOLUTION: A delay time T0 of a quick-return mirror of the fundus camera and a remote release delay time T1 of the digital single-lens reflex camera are set and their dimensions are compared. When the delay time T0 is larger, a difference is set in a time difference Ta to actuate the quick-return mirror. When the remote release delay time T1 is larger, the time difference Ta is set similarly, a remote release signal is outputted and after the lapse of the time difference Ta, an X contact signal is turned on. When the X contact signal S2 is turned on, this apparatus confirms the turn-on of a quick-return mirror retreat signal and allows an imaging light source to emit a light. This apparatus restricts a waiting time in a process for waiting the ON of the X contact signal and the quick-return mirror signal, when no signal is inputted during the prescribed time, performs an error process and prevents the imaging light source from emitting a light.
