Latest Patents

One of Nakaya's latest patents is titled "Method and apparatus for image reading capable of obtaining adequate white reference data for shading correction." This invention involves an image reading method where a reader is mounted to read one side of an original document. A contact glass is utilized, which includes a surface that contacts the original document. A reference is positioned on the opposite side of the contact glass and is movable between a reading position and a standby position. This reference has a surface with a predetermined color that provides shading data for correction purposes. The reader captures this shading data by reading the color on the reference surface at the reading position.

Another significant patent is the "Image reading apparatus and copier." This apparatus features a line sensor for reading an image of an original document. It includes a scanning optical system with a light source that scans the original. A reference reflection member reflects light emitted from the light source, while a buffer memory stores the image data. The apparatus also has an intermittent reading part that manages the scanning process based on the buffer memory's storage capacity. Additionally, a light amount variation correction part adjusts for any changes in the light source's intensity during scanning interruptions.
