Abstract
PURPOSE: To simplify the connection constitution and prevent occurrence of malfunction, by providing a diode between a synchronizing contact and a synchronizing terminal of a camera to reduce the number of synchronizing terminals.
CONSTITUTION: Through terminals B1, B1' of a synchronizing terminal B, the negative side potential of a power source 1 of a strobe unit A becomes the reference voltage for comparison of control power source circuit E, voltage display circuit F, emission checking display circuit G and dimmer control circuit H of a camera C, and a diode I is provided between terminal B2' of the terminal B and a synchronizing contact J of the camera C, so that the current may not flow back to the terminal B2' even if the terminal B2' side potential becomes negative. Therefore, power is supplied from circuit E, and the circuit F to indicate the charged voltage of main capacitor 6 of the strobe A, the circuit G to confirm emission of discharge tube 22 of the strobe A, and the circuit H are operated by receiving different pieces of information. As a result, the strobe unit and the camera may be connected easily with two wires along, and the number of terminals is reduced, so that occurrence of malfunction due to short circuit or the like may be prevented.
