ABNORMALITY DETECTING DEVICE, IMAGE READER, IMAGE FORMING APPARATUS, ABNORMALITY DETECTION METHOD AND CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To save space for an abnormality detection mechanism, to improve productivity and to suitably detect abnormality, when detecting the abnormality of a light source in an image reader on the basis of an electric state in the power supply terminal of the light source. Ž

SOLUTION: The abnormality detecting device includes a timing clock generation part 131 for outputting SLEDto an LED driver 133 and outputting SCTRto an abnormality detection circuit 133, and an engine control part 102 for controlling a timing determination operation of determining the output timing of the SCTR. The abnormality detection circuit 134 outputs a signal indicating that the light source is abnormal as SERRwhen executing the abnormality detection of the light source in the non-lighting state of the light source 122a, and the engine control part 102 determines the output timing of the SCTRon the basis of the signal state of the SERRafter the SLEDand the SCTRare output in the timing determining operation.
