ABSTRACT:
An imaging device has an optical scanning unit movably housed in a housing below a transparent document support for optically scanning a document placed on the transparent document support. The transparent document support can selectively be covered with a cover hinged to the housing. A semitransparently opalescent diffusion plate is mounted on the cover in facing relationship to the transparent document support. The cover houses a lamp unit for emitting light through the diffusion plate toward the transparent document support to irradiate the document placed thereon. A reflective document placed on the document support is irradiated by light emitted from the optical scanning unit. A reflected optical document image is applied through the optical scanning unit to an image sensor. A transmissive document placed on the document support is irradiated by light emitted from the lamp unit in the cover, and a transmitted optical document image is applied through the optical scanning unit to the image sensor. The lamp unit has lock mechanism for locking the lamp unit against movement in the cover when desired.
