PURPOSE:To attain the miniaturization and cost reduction of the document reader of a copying machine, etc. CONSTITUTION:In a state where an ADF device 3 is set in an optical unit 1, a connecting gear 15 is engaged with a connecting gear 17 provided on the optical unit 1. The connecting gear 17 is connected to a shared driving motor 4 via an ADF driving electromagnetic clutch 22. When a document 201 placed on a table glass 14 is read, an electromagnetic clutch 21 is turned on to operate the shared driving motor 4 and move a reading unit 2 along a guiding shaft 9. When a document 202 is read by the ADF device 3, first, the electromagnetic clutch 21 is turned on to move the reading unit 2 to the right end of the optical unit 1. After that, when the electromagnetic clutch 22 is turned on, the shared driving motor 4 is operated and a platen roller 11 can be driven so as to move the document 202.
