<p>PURPOSE:To realize a system which has only one menu control part even in the case of plural menus by having a menu display data and a menu picture control data storing address. CONSTITUTION:At the time of selection of processing based on menu, a control part 2 start up a menu control part 7 and set a menu picture control data storing address 6 as the address of the first menu. The menu display data is read out from the menu picture control data and inputted to a display device 3. When a menu item selection number has been inputted from an external input part 1, the menu control part 7 checks validity/invalidity of an input number. When a menu item decision code has been inputted from the external input part 1, the next menu picture control data address is read out and if the menu selection has not completed, it is set as the menu picture control data address. Thus, even in the case of plural menus, it is unnecessary to have menu control parts of the same number as that of the menus.</p> |
