More specifically, as shown in (b-1) of FIG. 2, when the sound of sound pattern 1 (or a change in volume level, a change in output time of different volumes, etc.) is output, the pressure of the air bean is low. If the residual pressure information is provided and the sound of sound pattern 2 (or volume change, output time change of different volume, etc.) is output as shown in (b-2) of FIG. Residual pressure information indicating suitability is provided and, as shown in (b-3) of FIG. 2, when a sound of sound pattern 3 (or a change in volume level, a change in output time of different volumes, etc.) is output, the residual pressure in the air cylinder is output.
