<P>PROBLEM TO BE SOLVED: To effectively prevent a data leakage from an output buffer from occurring while using a buffer memory in an inputting/outputting device which is loaded on a compound machine. <P>SOLUTION: An output buffer detecting process is constituted of an output managing section which detects an interruption of an output process, and an output data processing section 100 which deletes data of an output data storage section (output buffer) by the output interruption command from the output managing section 200. Thus, the data leakage from the output buffer is prevented from occurring. Moreover, the data leakage of pay data is prevented from occurring by monitoring the state of an accounting device 1a, and performing the interruption process for the starting process and the output process based on the state of the accounting device 1a. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
