の範囲第１項記載の装置。[Scope of Claim for Utility Model Registration] (1) Shutter speed setting means for manually setting the shutter speed S using an up/down switch that increases or decreases a set value; Flash synchronization speed S
a set value high/low determination means for determining whether the set shutter speed S is faster than 0 , and temporarily stores the set shutter speed S as M when it is determined that the set shutter speed S is faster than the flash synchronization speed S0 . a set value storage means for storing a main capacitor; After the charging completion signal disappears, the set shutter speed S
A shutter speed setting device comprising: a shutter speed setting value rewriting means for rewriting a value M to a temporarily stored value M. (2) The shutter speed set value rewriting means is characterized in that when rewriting the set shutter speed S to a speed that is less than or equal to the flash synchronization speed S0 , the shutter speed setting value rewriting means rewrites the set value to a lower speed value when slow synchronized shooting is being performed than when otherwise. The device according to claim 1 of the utility model registration claim.
