CONSTITUTION:A necessary operation screen is divided into multiple operation small screens so that respective operation parts displayed in a display device have areas that can easily be touched. An operation small screen program 7 for displaying the respective operation small screens and a keyword list 8 identifying the respective operation small screen programs are stored in a storage device 6. The keyword list 8 of the storage device 6 is retrieved for keyword input from a keyboard 3 and the identification number of the operation small screen program 7 concerned is detected. The operation small screen program 7 concerned is called from the storage device 6 based on the identification number and it is displayed in the display device 1. Thus, a precise touch operation can be executed from the small display device 1.</p> |
