PURPOSE:To perform the setting of a parameter extremely natually by driving successively a device which displays a setting state with the output of a means to detect the fact that an operator is operated successively, and changing a state to a prescribed setting state when the output of the detecting means shows change from presence to absence. CONSTITUTION:When the operator 1 is operated successively, the detecting means detects the fact that the operation is performed, and drives a display device 3 successively, therefore, the display of the display device 3 is varied one after another. Meanwhile, assumption to change the setting with the output of the detector 2 is applied to a parameter setting device 4, however, no change is applied to the state of a main body, and no changed state in outside appearance is set. When the output of the device 2 shows the change from presence to the absence, the state of the main body is changed, which sets the change state in the outside appearance. In other words, the operator 1 is operated until a prescribed state is set, and no change to a new setting state is performed until the operation is completed. In such a way, the setting of the parameter can be performed extremely natually. |
