PROBLEM TO BE SOLVED: To simplify and miniaturize a circuit by driving the back light of a liquid crystal panel and an ultraviolet lamp for fixation for thermosensitive recording by a common inverter. SOLUTION: In a digital camera with a thermosensitive printer, a camera part and a printer part are integrated. The inverter 23 is composed of an oscillation transformer 61 and an oscillation control circuit 62. The oscillation control circuit 62 converts DC power from a power supply battery 57 to AC power and drives the oscillation transformer 61. The oscillation transformer 61 is provided with a first output terminal 61a for outputting the driving signals of the voltage and frequency for the back light 21 and a second output terminal 61b for outputting the driving signals of the voltage and the frequency for fixing lamps 51 and 52. The back light 21 for illuminating the liquid crystal panel 6 is connected through a switch 24 for the back light to the first output terminal 61a, and the fixing lamps 51 and 52 are connected to the second output terminal 61b. The fixing lamps 51 and 52 are selectively lighted during printing.
