PURPOSE: To receive a timely notice without waiting on a machine device side at all times and smoothly perform machine operation by generating a characteristic discrimination sound when each mechanism part operates. CONSTITUTION: A sound determination part 6 inputs information regarding the operation states of respective mechanism parts from a machine operation control part 3 and determines a discrimination sound with distinctive-to-hear contents, and a sound generation part 7 generates the determined sound. With detection information from a human body detection part 9, a sound meaning the presence of a person is selected and the sound beings to be generated. Further, the sound is continuously generated while the person is present and while the mechanism part is in operation and if nobody is in front of the machine device when one work is finished by the machine device, the generation of the sound is ended. Consequently, the state wherein the user occupies the device is made evident including a preparatory period and other persons who want to use the device can know the usable state of the device only by paying attention to a sound without monitoring the device. |
