An image reading apparatus includes a reading unit, a cable, a connector portion, a casing, and a cover member. The reading unit reads an image of a document. The cable is connected to the reading unit, and transmits an image signal output from reading unit. The connector portion is disposed in the reading unit, and is connected to the cable. The casing accommodates the reading unit and has an opening portion through which the connector portion is exposed to outside of the casing. The cover member is attached to and detached from the casing and covers the opening portion in a state where the cable is connected to the connector portion via the opening portion.

A document backing extending in a plane is resiliently biased in a direction substantially parallel to the plane.

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.

An imager apparatus useful for a digital architecture lithographic printing system includes a first imager bank having at least one imager configured to produce a first output beam; and a second imager bank having at least one imager configured to produce a second output beam, the second imager bank being located at a first angle with respect to the first imager bank, the first output beam and the second output beam being separated by a second angle which is less than the first angle.

An image reading device includes a board including a plurality of imaging elements arranged along a scanning direction, and a housing including a plurality of optical components that are arranged along the scanning direction and a plurality of housing components that are arranged along the scanning direction. Each of the plurality of optical components focuses light reflected by a reading target onto a corresponding imaging element, and each of the plurality of housing components holds at least one optical component. The plurality of housing components are arranged to have a clearance therebetween and each of the plurality of housing components is fixed to the board at a position to transmit light through the optical components to focus onto the corresponding imaging element.
