A document reading device includes: an image capturing member that captures an image of a document; a placement portion that is disposed below the image capturing member and that has a boundary line between multiple surfaces at a position at which the boundary line is covered by the document when the document has a maximum size that the image capturing member is capable of imaging and the document is placed on the placement portion; and a document reading member that reads the document that is placed on the placement portion.

A document reading device includes an imaging unit that images a document, a placing portion that includes a first placing portion and a second placing portion and that has a placing surface on which the document is placed, the placing surface being formed by the first placing portion and the second placing portion, and a detector that detects an edge of the document that is placed on the placing surface by using a color difference or a luminance difference between the placing surface and the document. An end portion of the first placing portion adjacent to the second placing portion extends toward the second placing portion beyond an end portion of the second placing portion adjacent to the first placing portion.

An image reading apparatus includes a reading member that reads an image of a document that is transported, a discharge portion onto which the document that is read by the reading member is discharged, a placement portion that is installed above the discharge portion, an object being placed on the placement portion such that at least a part of an upper surface of the reading member is covered, and an image capturing member that is installed above the placement portion and that captures an image of the object that is placed on the placement portion.

An image processing apparatus includes a medium discharge portion onto which a medium to be taken out by a person with the person standing is discharged, a placement portion that is installed above the medium discharge portion, an object in color that is represented by using a Y-value closer than a value that represents black color to a value that represents white color where the color is represented by using a Y-value that represents luminance in a YCbCr method being placed on the placement portion, an image capturing member that is installed above the placement portion and that captures an image of the object that is placed on the placement portion. Color of an upper portion of the placement portion is represented by using a Y-value closer than the value that represents the white color to the value that represents the black color where the color is represented by using the Y-value that represents the luminance in the YCbCr method such that the object and the placement portion are distinguishable from each other in the image that is captured by the image capturing member.

A scanning optical system is provided including a source of optical radiation; an optical scanning beam delivery system for delivering optical radiation to a subject, wherein the optical scanning beam delivery system includes a plurality of optical elements including at least one steerable mirror; at least one actuator coupled to the at least one steerable mirror; a detection system for detecting optical radiation returned from a subject; a communications device including a user interface and configured to process a set of instructions at least partially responsive to inputs from the user interface; a controller comprising memory, a microcontroller and an field programmable gate array (FPGA), the microcontroller and FPGA receiving instructions derived from the communications device; and at least one actuator coupled to the at least one steerable mirror. The at least one actuator receives a first instruction set from the microcontroller in the form of sequential commands and a second instruction set from the FPGA in the form of concurrent commands. The first instruction set establishes a pattern of motion of the at least one steerable mirror at least partially responsive to inputs from the user interface of the communications device. The second instruction set modifies an attribute of the pattern of motion of the at least one steerable mirror in substantially real-time at least partially responsive to one or more triggering events.

A radiation image reading device includes: a light scanning unit; a light detection unit. Each of a transmittance when the excitation light reflected from the surface of the recording medium is transmitted through the optical filter and a transmittance when the signal light emitted from the surface of the recording medium at an angle larger than a predetermined angle with respect to a direction perpendicular to the scan line within the detection surface is transmitted through the optical filter is smaller than a transmittance when the signal light emitted from the surface of the recording medium at an angle smaller than the predetermined angle with respect to a direction perpendicular to the scan line within the detection surface is transmitted through the optical filter.

Disclosed is a magnification device for use by blind and/or low vision individuals. The device includes an X-Y table upon which an item to be magnified can be placed. A stationary camera arm and a pivotal monitor arm are oriented over the X-Y table. The monitor arm includes a video monitor pivotally mounted at its distal end. The camera arm also includes two laterally disposed lighting arms. A series of controls are provided along a lower edge of the monitor via a mounting bracket.

A spring compression assembly is configured to apply a load to a stack of electrochemical cells. The assembly includes a ceramic leaf spring, a tensioner configured to apply pressure to a first side of the spring and a bottom plate located on a second side of the spring opposite the first side of the spring. The bottom plate is configured to transfer a load from the spring to the stack of electrochemical cells.

A document camera system includes a page-turning device, an image pickup unit, a specification unit, a recognition unit, a determination unit and a notification unit. The page-turning device turns pages of a book. The image pickup unit picks up an image of each turned page. The specification unit specifies a page number portion in the image picked up by the image pickup unit. The recognition unit recognizes characters in the page number portion specified by the specification unit to identify a page number. The determination unit determines correctness of the order of the page numbers identified by the recognition unit. The notification unit notifies a user of an error when the determination unit determines that the order of the page numbers is incorrect.

A scanner includes a lower unit and an upper unit. The lower unit includes a first document table on which a first document is to be placed. The upper unit includes a second document table on which a second document is to be loaded and a document feed path through which the second document is to be picked up from the second document table fed, the upper unit being coupled to the lower unit to pivot between a closed position in which the first document table is covered and an open position in which the first document table is exposed. The upper unit further includes a reading unit to read an image from the first document and the second document by performing flatbed scanning on the first document and document feed scanning on the second document.
