PROBLEM TO BE SOLVED: To facilitate handling of cords around power supply and to prevent the feasibility of making a power capacity defiency by connecting an image photographing device to a print device via a connecting means and feeding to the image photographing device from the print device side via a feeding line included in the connecting means. SOLUTION: A power feeding part 320 performing power feeding to each part of a camera feeds power supply from a printer side through a USB cable 50 and a USBI/F 213, when a digital camera is connected to the printer. However, since power that can be fed to the digital camera is about 2.5 W and the printer 30 side consumes considerable power during printing, there is a possibility of making the feeding amount to the digital camera insufficient and to invite malfunctions if a back light 10B is turned on. Thereby, an LED 220 for display that does not make power consumption a problem is turned on and the back light 10B is turned off from data transmission till printing completion. |
