PROBLEM TO BE SOLVED: To provide a display operation device capable of making an instruction to start a next process even during execution of a process.SOLUTION: In an operation unit 120, a touch panel display 130 includes a display panel 132. A CPU 300 causes the display panel 132 to display a monochrome start key and a color start key. In response to an input operation on the monochrome start key or the color start key, the CPU 300 starts a monochrome printing process or a color printing process. In response to starting of the process, the CPU 300 prohibits reception of the input operation on the monochrome start key or the color start key. When a predetermined period of time has elapsed after the process is started, the CPU 300 allows reception of the input operation on the monochrome start key or the color start key. |
