A lighting device includes: a first board and a second board; a first light-emitting element mounted on the first board; a second light-emitting element mounted on the second board; and a base member including a first attachment face to which the first board is attached; and a second attachment face to which the second board is attached. As the lighting device is viewed from a light-emitting side, the first attachment face is disposed in front of the second attachment face. The second attachment face has an overlap area in which the second attachment face overlaps the first attachment face. The second light-emitting element is disposed in an area of the second attachment face different from the overlap area.

An image reading apparatus of the present invention is provided with a driving unit for supplying a driving force to a scanner module and for supplying a driving force to an ADF. Changeover between the driving force for the scanner module and the driving force for the ADF is carried out by moving the scanner module, where the driving force of the scanner module and the driving force for the ADF are supplied from a single driving force source. A low cost member is used for the changeover of driving force transmission where the same driving force source (motor) supplies necessary driving force for a fed document reading mode and for a stationary document reading mode. This lowers a cost of the apparatus.
