<p>PURPOSE:To control multiple light emissions of an automatic strobe without intricating the terminal construction on a camera side by distributing light emission signals in correspondence to time series dimming signals by means of a serial-in and parallel-out type shift register. CONSTITUTION:An adapter F forms a serial-in and parallel-out type shift register by 3 stages of flip-flops FF1-FF3 and outputs Q1-Q3 are generated successively from the flip-flops FF1-FF3 according to the sequential time series dimming signals corresponding to the sequential set dimming time from a TTL camera D, whereby light emission signals are distributed. The putting out of a strobe A and putting on of a strobe B are controlled by the output Q1, the putting out of the strobe B and the putting on of a strobe C by the output Q2 and the putting out of the strobe C by the output Q3. Thus even when the number of strobes increases, the multiple light emissions of the automatic strobe having interchangeability with the case of a single strobe is controlled by the simple constitution which does not require an increase in the number of terminals on the camera side.</p> |
