PURPOSE:To drive away a feeling of uneasiness in terms of operation and anxiety of an operation miss, and to enable an adequate judgement in case of an error by reading the progress state of the control procedure of the equipment from a display part and then by making the cause of an error clear when it occurs. CONSTITUTION:A received signal, inputted from circuit 1, is amplified 3, passes through BPF5 and rectifying circuit 9, for example, and is sent to micro computer 17 via signal line 13. Then, the signal sent out of computer 17 turns on LEDs 15a... 15p to make displays 16a...16p of the progress state of the control method of the equipment. Consequently, the progress state of the control method of the equipment can be read by display parts 16a...16p and when an error occurs, its cause is made clear, so that while a feeling of uneasiness in terms of operation and anxiety of an operation miss are are driven away, an adequate judgement can be made in case of the error. |
