Claims

[Claims for Utility Model Registration] (1) A plurality of strobes each having a light emission start signal input terminal and a light emission stop signal input terminal, and a trigger signal generated when the shutter of the camera is fully opened is used to trigger each of the plurality of light emission of the plurality of strobes. A first output circuit applies a start signal to an input terminal in parallel, and a light emission stop signal is generated when an integral value of reflected light from a subject when the plurality of strobe lights are emitted reaches a value corresponding to an appropriate exposure amount. A multifunction flashlight system characterized by comprising: a photometric circuit that generates a photometric signal; and a second output circuit that applies a light emission stop signal sent from the photometric circuit to each of the light emission stop signal input terminals of the plurality of strobes in parallel. Light strobe photography device. (2) Claim 1 of the utility model registration, which is characterized in that the photometry circuit starts integrating the reflected light from the object after a predetermined time delay from the generation of the trigger signal.
The multi-flash flash photography device described in Section 1. (3) A utility model registration claim characterized in that a second output circuit applies a light emission stop signal sent from the photometric circuit to each of the light emission stop signal input terminals of the plurality of strobes through buffer amplifiers. A multi-flash flash photography device according to scope 1. (4) A request for registration of a utility model characterized in that the second output circuit applies a light emission stop signal sent from the photometric circuit to each of the light emission stop signal input terminals of the plurality of strobes via a latch circuit, respectively. The multi-flash flash photography device according to item 1.
