In a case where a user places a document placed on a document positioning glass plate without sufficiently opening an automatic document feeding device, sheet size information will not be reset and an image may be read based on incorrect size information. Therefore, in the present invention, an angle at which the size information is reset is set to an angle between a first angle at which the automatic document feeding device is closed, and a second angle (&thetas;1) at which the automatic document feeding device is moved to open automatically after being released from a holding state by a holding unit. |
