Abstract
An adaptor for an auto strobo unit comprises a trigger signal feed circuit for supplying a trigger signal to a flashlight trigger circuit of said auto strobo unit in response to the closure of a synchro contact of an automatic exposure controlled camera, a polarity inverter for inverting the polarity of an illumination interrupt signal supplied by a photometric control circuit of the camera to a polarity which is suitable to activate an illumination interrupt circuit of the auto strobo unit, an amplifier for amplifying an illumination interrupt signal to a given level, and circuit means for feeding the polarity inverter or the amplifier when the trigger signal feed circuit is operated. The adaptor enables an automatic exposure controlled camera to be combined with any kind of an auto strobo unit.
