An image communication apparatus, which stores image data in a first memory, and transfers the image data from the first memory to a detachable external storage medium, includes a detection unit for detecting an insertion/detachment state of the external storage medium, a transfer unit for transferring image data in the external storage medium to the first memory upon insertion of the external storage medium, and a delete unit for deleting the same image data stored in the first memory as the image data stored in the external storage medium upon detachment of the external storage medium.

DETAILED DESCRIPTION It is an object of the present invention to improve an image communication apparatus in consideration of the above-mentioned problems.
It is another object of the present invention to provide an image communication apparatus, which can efficiently use a memory by deleting the same image data stored in the memory of the apparatus as that stored in an external storage medium while the detachable external storage medium is detached.
It is still another object of the present invention to provide an image communication apparatus, which can improve use efficiency of a memory by transferring image data stored in a detachable external storage medium to the memory of the apparatus upon insertion of the external storage medium, and by deleting the same image data stored in the memory of the apparatus as that stored in the external storage medium upon detachment of the external storage medium.
Other objects of the present invention will become apparent from the following detailed description of the preferred embodiments taken in conjunction with the accompanying drawings.
