Abstract

For use in copying data between a plurality of recording media, the present invention provides a data processing device adds up the amounts of data on a plurality of files recorded on a transmitting medium to thereby detect the total amount of copy data, displays an intermediate result of addition on a display unit while updating the result displayed during a process from the start of addition of the amounts of file data until the completion of addition and displays the final result of addition on the display unit upon the completion of addition. The user is unlikely to feel uneasy even when the detection of the total amount of copy data takes time.

Claims

1. A data processing device capable of copying data between a plurality of recording media and comprising an arithmetic processor for adding up the amounts of data on a plurality of files recorded on a transmitting medium to thereby detect the total amount of copy data, a display unit for displaying the total amount of copy data detected, and a display controller for displaying an intermediate result of addition on the display unit while updating the result displayed during a process from the start of addition of the amounts of file data by the arithmetic processor until the completion of addition and displaying the final result of addition on the display unit upon the completion of addition.

2. A data processing device according to claim 1 which further comprises a detector for detecting the data recordable capacity of a receiving medium and wherein the display controller displays on the display unit the detected data recordable capacity along with the total amount of copy data.

3. A data processing device according to claim 1 wherein the arithmetic processor starts to detect the total amount of copy data upon turning on a power source or a change of medium or in response to a copying command signal.

4. A data processing device according to claim 1 wherein the display controller comprises a display updater for updating the added value displayed at timing in accordance with the value of at least one of elapsed adding-up processing time, added value and the number of files processed for addition during the process from the start of addition of the amounts of file data by the arithmetic processor until the completion of addition.

5. A data processing device according to claim 4 wherein the display updater comprises an updating interval changer for altering the updating interval in accordance with the value of at least one of the elapsed adding-up processing time, the added value and the number of files processed for addition.

6. In copying data between a plurality of recording media, a data copying method comprising executing a process for adding up the amounts of data on a plurality of files recorded on a transmitting medium to thereby detect the total amount of copy data, displaying an intermediate result of addition on a display unit while updating the result displayed during a process from the start of addition of the amounts of file data until the completion of addition and displaying the final result of addition on the display unit upon the completion of addition.

7. A data copying method according to claim 6 wherein the detection of the total amount of copy data is started upon turning on a power source or a change of medium or in response to a copying command signal.

8. A data copying method according to claim 6 wherein the added value displayed is updated at timing in accordance with the value of at least one of elapsed adding-up processing time, added value and the number of files processed for addition during the process from the start of addition of the amounts of file data until the completion of addition.

9. A data copying method according to claim 8 wherein the updating interval is altered in accordance with the value of at least one of the elapsed adding-up processing time, the added value and the number of files processed for addition.
