PROBLEM TO BE SOLVED: To give information about a progress state of a sequence to a user intelligibly, even after starting a signal output operation. SOLUTION: A plurality of signal patterns are displayed in accordance with the sequence on a displaying device of a signal generating apparatus, and if an output starting operation of the signal patterns is carried out subsequently, a current output or output waiting signal pattern is displayed so as to be capable of being identified from other signal patterns. At this point, each signal pattern may be displayed so as to correspond to an identifier such as an index number. The identifier may be made blinking for example, in order that the identifier of the current output or output waiting signal pattern can be identified. Alternatively, the identification may be made by carrying out displaying using a color different from those of other signal patterns, for example, by reversing the color of the current output or output waiting signal pattern.
