PROBLEM TO BE SOLVED: To provide the information transmission display device or the like by which a command or the like once having been executed is freely canceled. SOLUTION: A history collection and storage means 68 collects history data for processing information by an information processing means 66 and stores the data. The information processing means 66 references history data stored in the history collection storage means 68 based on a cancelation instruction to cancel the information processing corresponding to the history data designated by the cancelation instruction. Furthermore, the information processing means 66 sends the cancelation instruction to other information transmission display device 54 via a communication means 64. Thus, a command or the like having been once executed is freely canceled by any device. |
