Abstract
An image reading apparatus includes a document placement surface, a document cover that rotates between a closed state and an open state, a pressing portion that is disposed on the side of the document table and presses a switch, a rotary lever that is disposed on the side of the document cover and applies external force to the pressing portion, and a biasing member that biases one end side of the rotary lever in a direction that moves away from the document cover, in which when the document cover is at a predetermined angle, one end of the rotary lever pushes down the pressing portion to change the state of the switch, and in the process of displacement from the predetermined angle to the closed state, the one end of the rotary lever rotates in a direction approaching the document cover and maintains the state of the switch.
