The present invention discloses a double-sided synchronous scanning device. A scanning channel is formed between two scanning components; two backlight plates are respectively used to provide backlight for an opposite-side scanning component and fixed with the same-side scanning component; one side of each backlight plate facing the scanning channel is provided with a light guide groove corresponding to a light inlet of the corresponding scanning component; a backlight source is arranged in the light guide groove. When the two scanning components work synchronously, because the backlight plates always need to provide backlight for the opposite-side scanning component, and the reflected light generated by the backlight plates on a scanned sample enters the light inlet of the same-side scanning component, which will affect the image scanning effect.

Disclosed herein is a method, comprising: scanning a scene for a first scan in a scanning direction with M detector blocks (detector blocks (i), i=1, . . . , M), wherein the M detector blocks are physically arranged in the order of the detector blocks (1), (2), . . . , (M) in the scanning direction during the first scan, M being an integer greater than 1; and after the first scan, scanning the scene for a second scan in the scanning direction with the M detector blocks, wherein the M detector blocks are physically arranged in the order of the detector blocks (M), (1), (2), . . . , (M−1) in the scanning direction during the second scan.

A reading apparatus includes a main body that includes an original document plate and a reading portion configured to read an image from the original document, and an operation portion that is attached in the original document plate. The operation portion includes: a front face casing portion; and a rear face casing portion that is engaged with the front face casing portion at an operation surface. An upper end portion of the operation portion is as high as the original document plate or higher than the original document plate, and in an engaging portion of the front face casing portion and the rear face casing portion at the upper end portion, an upper edge of the front face casing portion has a shorter distance to the lower end portion of the operation portion than the upper edge of the rear face casing portion.

The present invention relates to novel linear and cyclic polypeptides that bind to IL-23 receptor and inhibit the binding of IL-23 to its corresponding receptor and cell signaling thereof. The novel polypeptides of the present invention has a core structure of WX.sub.1X.sub.2X.sub.3W, where W is tryptophan, and X.sub.1, X.sub.2 and X.sub.3 are amino acids, with the proviso that when one of X.sub.1, X.sub.2 or X.sub.3 is W, the remaining two of X.sub.1, X.sub.2 or X.sub.3 cannot be W. Preferred core structures include WVDYW or WQDYW. The present invention relates a composition containing the novel polypeptides (linear or cyclic), and use of same in inhibiting cell functions including production of IL-22 and IL-17F from immune cells as well as in treating IL-23 associated human diseases including, for example, inflammatory bowel diseases, psoriasis and Crohn's disease, ulcerative colitis and multiple sclerosis.

A printer has: a recording unit having a recorder that makes a record on a medium; and a scanner unit having a reader that reads an original placed on an original table, the scanner unit being disposed on the top of the recording unit. The scanner unit is horizontally shift between a first position at which the recording unit is used and a second position, which is a maintenance position of the recording unit.

An image processing apparatus includes a reading unit and a controller. The reading unit radiates light to a target from two directions with different angles and reads images of the target. The controller performs, when controlling the reading unit to acquire the two images of the target, control such that a resolution of the image read by radiating the light to the target from one of the two directions is lower than a resolution of the image read by radiating the light to the target from the other one of the two directions.

An image reading apparatus is connectable to an information processing apparatus having predetermined software and includes at least a processor and at least a memory coupled to the processor and having stored thereon instructions. The instructions are executed by the processor to act as a reading unit to perform scan processing for a document in a case where a read command transmitted from the information processing apparatus by user operation to the predetermined software is received, a detection unit to detect an error in the image reading apparatus, and a transmission unit to execute image data transmission processing for transmitting image data corresponding to the detected error in a case where the detected error is a first error, and execute error transmission processing different from the image data transmission processing in a case where the detected error is a second error.

An image processing device includes a light source, a reader, and circuitry. The light source is configured to irradiate an object at least with invisible light. The reader is configured to read a first image from the object irradiated with the invisible light. The circuitry is configured to generate a second image from the first image read by the reader. The circuitry is configured to recognize first information in the second image.

To provide an image reading apparatus capable of informing a user of the status of the image reading apparatus in a form understandable to the user without increasing a size or a cost, a control method of the image reading apparatus, and a program, explanatory image data is transmitted to a host computer instead of document image data in a case where an abnormality in the image reading apparatus is detected.
