Scanner device and image forming apparatus

摘要

A scanner device has a first mode for reading a normal object placed on a document table and a second mode for reading a self-luminous object placed on the document table. The scanner device includes a light detecting portion and a control portion. The light detecting portion detects light from an object placed on the document table. The control portion switches the reading mode between the first mode and the second mode on the basis of a detection result of the light detecting portion. When an image sensor detects light from the object placed on the document table in the second mode, the sensitivity of the image sensor is automatically adjusted in accordance with the amount of the detected light.
