## Abstract

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.

## Claims

### Claim 1

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, comprising:
detection means for detecting an insertion/detachment state of said external storage medium;
transfer means for transferring image data in said external storage medium to said first memory upon insertion of said external storage medium; and
delete means for deleting the same image data stored in said first memory as the image data transferred from the first memory to said external storage medium upon detachment of said external storage medium.

### Claim 2 (depends on 1)

An apparatus according to claim 1, further comprising a second memory for storing management data for managing the image data in said first memory, and wherein the image data is deleted according to the management data stored in said second memory.

### Claim 3 (depends on 1)

An apparatus according to claim 1, wherein received image data is stored in said first memory, and thereafter, the image data is transferred from said first memory to said external storage medium.

### Claim 4 (depends on 1)

An apparatus according to claim 1, further comprising:
instruction means for issuing an instruction for deleting arbitrary image data in said external storage medium; and
means for deleting the image data in said first memory and the image data in said external storage medium according to the instruction from said instruction means.

### Claim 5 (depends on 1)

An apparatus according to claim 1, wherein said transfer means transfers some of image data stored in said external storage medium.

### Claim 6 (depends on 1)

An apparatus according to claim 1, wherein said delete means deletes some of image data stored in said external storage medium.

### Claim 7

An image communication apparatus comprising:
means for generating image data;
first memory means for storing the image data;
a detachable external storage medium;
transfer means for transferring the image data in said first memory means to said external storage medium, and transferring image data in said external storage medium to said first memory means;
detection means for detecting an insertion/detachment state of said external storage medium; and
delete means for deleting the image data in said first memory means,
wherein said transfer means transfers the image data in said external storage medium to said first memory means upon insertion of said external storage medium, and
said delete means deletes the same image data in said first memory means as the image data transferred from the first memory to said external storage medium, upon detachment of said external storage medium.

### Claim 8 (depends on 7)

An apparatus according to claim 7, wherein said transfer means discriminates the presence/absence of image data in said external storage medium upon insertion of said external storage medium, and transfers the image data in said external storage medium to said first memory means according to the discrimination result.

### Claim 9 (depends on 7)

An apparatus according to claim 7, further comprising a second memory for storing management data for managing the image data in said first memory, and wherein the image data is deleted according to the management data stored in said second memory.

### Claim 10 (depends on 7)

An apparatus according to claim 7, further comprising:
instruction means for issuing an instruction for deleting arbitrary image data in said external storage medium; and
means for deleting the image data in said first memory and the image data in said external storage medium according to the instruction from said instruction means.
