Abstract:
1. An original reading apparatus comprising: an original platen; an original pressing member that presses an original placed on the original platen; a light source that irradiates light toward the original platen; a reading device that reads reflected light of the light irradiated from the light source toward the original platen; an open state-detecting device that detects that the original pressing member is closed down from a first open state to a second open state that is more closed than the first open state, and closed down from the second open state to a third open state that is not closed completely and more closed than the second open state; and a control device that turns on the light source based on the open state-detecting device detecting that the original pressing member is closed down to the second open state from the first open state, and determine a size of the original based on a reading result of the reading device in a state in which the original pressing member is in the third open state.
