Abstract

PURPOSE: To supply electricity simultaneously from both batteries by commonly connecting one electrode of a solar battery and a primary battery and connecting the other electrodes by way of a reverse current blocking diode.
CONSTITUTION: Now if it is assumed that large irradiated light is applied to a solar battery 1, the power supply from the battery 1 is made to an AE control circuit 6 and at this time, the photographing information obtained by photometry is displayed in a display device 7. Next, at the time when the circuit 6 makes shutter operation through release operation, it is necessary to supply large current to the circuit 6, and since the current supplied from the solar battery 1 is insufficient, a shutter 8 is operated by the power supplied from a primary battery 2.
