Abstract

Abstract PURPOSE:To decrease burdens on a power source at the peak time of power consumption and to keep the contents of a RAM by constituting a circuit in such a way that a power source is always kept on without making an input terminal of the power source of the RAM in an electronic view finder go through a switching means. CONSTITUTION:The voltage input terminal of the power source of the RAM 2 is directly connected to a main switch 6 without going through an analog switch 5. The electronic view finder has both functions to display moving pictures and to display still pictures. A shutter button has two-stage switches SW1 and SW2, and the switch SW1 is for photometry and the switch SW2 is for releasing. In an on/off switching means of the electronic view finder, thus, the circuit is constituted in such a way that the power source is always kept on without making the input terminal of the power source of the RAM 2 alone in the electronic view finder go through the switching means. Thus, the burdens on the power source at the peak time of power consumption decreases and the contents of the RAM can be kept.
