<P>PROBLEM TO BE SOLVED: To provide a multifunctional machine capable of improving the operability. Ž<P>SOLUTION: The multifunctional machine 10 includes mechanically configured hard keys 52 and touch panel buttons 100 displayed on a display panel 50 (touch panel). A CPU 14 sets the setting value of the hard key sound volume of the hard keys 52. Also, the CPU 14 sets the setting value of the touch panel button sound volume of the touch panel buttons 100. In S36-S40, the CPU 14 adjusts the setting value of the touch panel button sound volume that corresponds to the result of comparing the setting value of the hard key sound volume, with the setting value of the touch panel button sound volume. By adjusting the setting value of the touch panel button sound volume to exceed the setting value of the hard key sound volume, the presence/absence of an input operation can be confirmed in both buttons, and noise can be compatibly suppressed.
