Abstract
An original reading apparatus includes a thermistor that is arranged close to a reading position. When the output of the thermistor represents a warning temperature range, a CPU activates a cooling fan after waiting for completion of an automatic document feeding (ADF) copy operation being performed. When the output of the thermistor represents a proper temperature range due to the operation of the cooling fan, a state of enabling the ADF copy operation is restored. If the output of the thermistor exhibits an abnormal temperature range due to a cause of a failure in the cooling fan or the like, the CPU immediately stops all the operations.
