When deleting a plurality of files, the input / output device 6 acquires a list of files in the storage device 5 from the control device 3. This is for searching whether a file instructed to be deleted by the operator exists in the storage device 5.

When an instruction for a plurality of files to be deleted is input, the input / output device 6 searches for the files to be deleted in the order of the obtained file list.

For example, when deletion of the files A, C and D is instructed, the input / output device 6 searches the acquired file list for files in this order.

First, the input / output device 6 outputs an instruction to delete the file A to the control device 3, and the control device 3
Deletes the file A from the storage device 5 in accordance with the input instruction, rearranges the files B, C, D, and E after the file A (S12 in FIG. 12), Is output to the input / output device 6 to the effect that the deletion has been completed.

Next, the input / output device 6 outputs an instruction to delete the file C to the control device 3, and the control device 3
Deletes the file C from the storage device 5 in accordance with the input instruction and rearranges the files D and E behind the file C (S13 in FIG. 13).

Similarly, the input / output device 6 is connected to the control device 3
When the information indicating that the deletion of the file has been completed is input from, the instruction to delete the next file is output.

As described above, when the deletion of the file D following the file A and the file C is completed (S14 in FIG. 4), the input / output device 6 displays that the deletion of all the designated files is completed, and Ends the file deletion process. By the above operation, the file A, the file C, and the file D are deleted from the storage device 5.
