PURPOSE:To prevent a customer familiar with operation from feeling a voice to be noisy, and to dynamically adjust output sound volume in accordance with circumferential environmental sound. CONSTITUTION:A voice generating mechanism is put under the control of a timer mechanism 12, and a timer is given a voice number memory 13, a first delay time memory 14, and a second delay time memory 15. The timer mechanism 12 starts the voice generating mechanism and generates the voice after the lapse of first delay time when the instruction of stop is not issued from an application program, and further, it generates the voice again after the lapse of second delay time. When the instruction of the stop is issued from the application program, it does not generate the voice. The delay time is stored in a delay information storage part 16, and can be changed dynamically by a maintenance application program 20. |
