PROBLEM TO BE SOLVED: To shorten the input time when pieces of cell data that calculation expressions of other cells are referring to are successively changed by monitoring data input from an input device, starting operation with an input monitor trigger, and performing recalculation unless there is next data input for a certain time. SOLUTION: This processor is equipped with an input monitor part 11 which monitors key input, a cell range storage part 12 which stores a changed cell range, a time management part 13 which operates with a trigger from the input monitor part 11, and a recalculation execution part 14 which performs recalculation. When data is inputted to a cell, the input monitor part 11 generates a trigger and the time management part 13 waits for a certain time after receiving the trigger and performs recalculation unless a next data input report is received during the period. When the next data input report is received in the wait time, the time management part still waits further for a certain time without performing the recalculation. Therefore, a data input process never enters a wait state owing to a state wherein the recalculation is in process. |
