A reading apparatus comprising a lower case, a reading portion, a drive portion and a stay is used. The reading portion moves between an open position in which the lower case is open and a closed position in which the lower case is closed and accommodates a reading sensor. The drive portion moves the reading sensor in a moving direction. The stay is coupled to the reading portion rotatably in one end and coupled to the lower case rotatably in the other end and moves a rotation shaft with in a direction orthogonal to the shaft. The drive portion is located outside a movable range of the reading sensor. When the reading portion is in the closed position, the stay is disposed in an area in which the stay overlaps the drive portion in the moving direction and overlaps the drive portion in height direction.
