Patent ID: 7218426

Claim:
An image-reading apparatus for reading an image formed on a document, comprising: an automatic document feeder for automatically feeding the document; a dynamic-document reading section for reading the image when the automatic document feeder is feeding the document; a static-document reading section for reading the image when the document is stationarily placed on the static-document reading section; a document-covering member for covering and pushing the document onto the static-document reading section, said document-covering member being capable of opening and shutting with respect to the static-document reading section when the automatic document feeder is opened with respect to the dynamic-document reading section; a light source mechanism for irradiating an exposing light onto the document at one of the dynamic-document reading section and the static-document reading section, wherein the light source mechanism: (i) is stationary under the dynamic-document reading section when irradiating the exposing light onto the document being moved by the automatic document feeder through the dynamic-document reading section, and (ii) moves under the static-document reading section to scan the document by irradiating the exposing light through the static-document reading section, when irradiating the exposing light onto the document stationarily placed on the static-document reading section; an image-capturing element for receiving light reflected from the document to convert the image into electronic signals; and a shutter member which is movable between: (i) a shading position at which the shutter member blocks a portion of the exposing light emitted from the light source mechanism, and (ii) a non-shading position at which the shutter member does not block the exposing light emitted from the light source mechanism; wherein, when the document is moved by the automatic document feeder at the dynamic-document reading section to read the image formed on the document, the shutter member is positioned at the non-shading position, and when the document is stationarily placed on the static-document reading section to read the image formed on the document, the shutter member is positioned at the shading position.
