PURPOSE:To surely receive information and to improve the degree of freedom in an operator's working scope by providing an informing means which is pro vided in a remote control means and informs the presence or absence of the reception of a normal or periodic signal from a signal generation means and the content of the information corresponding to the detection state of a detection means, respectively. CONSTITUTION:The signal generation means 50 provided in a processor main body normally or periodically generates the signal. Therefore, in the case that the remote control means 90 exists within a range where the signal reaches, the signal is normally or periodically detected by the means 90 even when abnormality, etc., does not occur in the processor main body. Since the informing means L1-L5 provided in the means 90 inform the presence or absence of the reception of the normal or periodic signal from the means 50 and the content of the information corresponding to the detection state of the detection means 420, it is known based on the content of the information of the informing means L1-L5 whether the position of the means 90 is within or out of the specified range. Thus, the information is surely received and the degree of freedom in the operator's working scope is improved. |
