At a first time, an image sensor captures a first image including images of an object. A second supply section which is separate from the first supply section supplies a second liquid-phase raw material. The surface emission type of semiconductor device comprises a substrate, and an active layer, which is constituted of a composition selected from the group consisting of InGaAlP and InGaP and is provided on the substrate. A second extension member is positionable in the channel and is movable with respect to the second open end. When the voltage of the commercial power supply E drops, the smoothing capacitor Co1 operates as an input power supply to power the converter section PFC2, which allows the smoothing capacitor Co2 to supply the stabilized output voltage Vo2 to the load.
