PURPOSE:To dispense with inspection work and to rapidly perform repairing, by providing monitor means for monitoring the presence of trouble or abnormality on the basis of a signal state by informing the occurrence of the trouble or abnormality. CONSTITUTION:A monitor means for monitoring the presence of trouble or abnormality on the basis of a signal state and an information means for outputting the signal showing the occurrence of the trouble or abnormality are mounted and the occurrence of the trouble or abnormality is informed to an external host computer. For example, it is judged whether a signal TELG is 'H' to judge whether the sufficiently long time set by a timer circuit 26 is elapsed. As a result, when said signal is 'H', it is judged that the disconnection of the line of a start signal START is generated or a CCD control part is abnormal to transfer to the processing of an abnormality processing routine. |
