Abstract
A larynx stroboscope device capable of photography following the anode or cathode terminal of a flash discharge tube is connected to a photographing charge-discharge capacitor by the release operation of a camera. A trigger pulse is applied to the trigger terminal of the flash discharge tube in synchronization with a vocal cord vibration signal so that the flash discharge tube emits light while the shutter of said camera is open. Upon completion of a photographing operation, all the functions are automatically restored to the states obtained before the release operation. Alternatively, a charge-discharge system may be used. By the release operation of a camera supply of charging current to said capacitor is suspended. Thereafter a trigger pulse is applied to the trigger terminal of said flash discharge tube in synchronization with a vocal cord vibration frequency so that said flash discharge tube emits light while the shutter of said camera is open.
