加するように接続されている。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In Fig. 2, 1a is a power supply terminal to which the voltage of the camera power supply (10B) is applied, 7 is a diode provided between the input terminal of the memory circuit 6 and the power supply terminal 1a, and 8 and 9 are diodes for preventing backflow. , 1o is a charging capacitor that can be charged with the camera power supply, 11 is a solar battery, and diode 9
This is connected to charge the charging capacitor 12 via the diode 8 and to apply a voltage to the memory circuit 5 via the diode 8.
以上のよう（こ構成された本実施例について以下その動

まれた太陽電池１１てもって大容量の充電用コンデンサ
ー１２も充電される。太陽電池１１は約３ボルトである
ためダイオード８によってカメラ電源オン時には太陽電
池１１の電圧は利用されない。First, when the camera is powered on, a voltage of approximately 5 volts is supplied to the memory circuit 5 (approximately 5 volts) through the diode 9, and the memory circuit 5 is activated. At the same time, a large-capacity charging capacitor 12 is also charged by the solar cell 11 built into the camera body including the electronic viewfinder.Since the solar cell 11 has a voltage of about 3 volts, the diode 8 When the power is turned on, the voltage of the solar cell 11 is not used.

能をバックアップする。When the camera power is turned off, the aforementioned capacitors 12 and 10 start discharging into the memory circuit. At the same time, the solar cell 11 also charges the capacitors 12 and 10, supplies voltage to the memory circuit 5, and backs up the memory function.
よってカメラの電源が切れた後もメモリー機能がバンク
アップされる。Therefore, the memory function will be banked up even after the camera is turned off.
