PURPOSE:To make it possible to display a plurality of state variables without narrowing a spectral chart area, by limiting the display position of each state variable to one place of monitor display and displaying display content while successively changing over the same by a monitor key. CONSTITUTION:A key for changing over the contents of a plurality state variables is selected from soft keys and defined as a monitor key 30. In this case, the display position of the state variables is provided to the upper left side monitor display part 31 in the picture. Every when the monitor key 30 is pushed, the content to be displayed to the monitor display part 31 is changed over and a selector is changed over while state variables such as date or time are successively selected to be imparted to CRT. |
