发明名称 CAMERA HAVING BIMORPH DRIVING ELEMENT
摘要 PURPOSE:To charge a capacitor for a bimorph driving element rapidly and to attain continuous and rapid photographing by stopping the charge of a flash emitting capacitor at the time of the charging of the capacitor for the bimorph driving element. CONSTITUTION:Two boosted voltages are taken out from the secondary winding of a converter, a voltage V5 obtained through a diode D5 and a transistor (TR) TR10 out of the two voltages is supplied to a flash circuit and a voltage V3 through a diode D3 and a TR TR7 is supplied to an exposure control circuit 9. The circuit 9 includes a capacitor C2 for accumulating charge, a voltage detecting circuit BC1 for detecting the accumulating voltage to the capacitor C2 and a bimorph driving element Bi1 and the circuit BC1 outputs a detecting signal of an 'H' level to a microcomputer in case of detecting 200V. The microcomputer turns off TRs TR6-TR8 in switching circuits 7, 8 and the turns off a boosting control TR TR2 in a boosting circuit 5 to stop boosting.
