Abstract
Abstract An image sensing device includes a voltage converting device for supplying power for driving a peripheral equipment component such as a flash unit used with the image sensing device, a recording device for recording an audio signal and a control device for prohibiting simultaneous operation of the voltage converting device and the recording device. The control device has a control mode in which both the peripheral equipment and the recording device are used at the time of photography. The control device also has a control mode in which the peripheral equipment is operated in preference to the recording devide. Accordingly, the mixture of noise from the voltage converting device with the audio recording signal is prevented.
