First Claim
1. A digital camera that records data of a photographed picture to a removable record medium and reads picture data from the record medium, comprising:
- a controlling portion;
an operation input portion that outputs an operation signal to the controlling portion;
a buffer memory that is controlled by the controlling portion and that is read from the record medium; and
a single USB controller that is controlled by the controlling portion, wherein the operation input portion selects a first USB interface or a second USB interface and selection information that represents the selected interface is stored in the controlling portion, and wherein when the controlling portion receives a transfer request from the USB controller, the controlling portion transfers data from the buffer memory to the USB controller through the first USB interface or the second USB interface corresponding to the selection information.

Abstract
An operation input portion 7, a buffer memory 8, a record medium 9, and a single USB controller 10 are connected to a bus connected to a controlling microcomputer 6. A USB connector 11 is connected to the USB controller 10. The USB controller 10 as hardware deals with a single interface. By a process of the controlling microcomputer 6, data is transferred from the buffer memory 8 to the USB controller 10 through one of USB interfaces corresponding to PTP and mass storage class interface. With a switch of the operation input portion 7 and a menu screen, the user sets a USB interface. Selection information representing the selected USB interface is stored in a memory of the controlling microcomputer 6.
