发明名称 Shutter speed setting apparatus
摘要 A shutter speed setting apparatus is provided which is arranged to respond to a main capacitor charge completion signal to judge whether or not the set value of a shutter speed S is higher than a flash synchronization speed S0. If it is judged that the set value of the shutter speed S is higher than the flash synchronization speed S0, the set value of the shutter speed S is temporarily stored in the form of a value M and the set value of the shutter speed S is forcibly rewritten with a given speed not higher than the flash synchronization speed S0. After the main capacitor charge completion signal has disappeared, the set value of the shutter speed S is again rewritten with the temporarily stored value M. If an up/down switch is operated so as to decrease the shutter speed, the set value of the shutter speed S is decreased from the shutter speed which is forcibly rewritten.
