    摘要： An image reading device includes a frame, an image reading unit, a guide, a biasing member, and an adjuster. The image reading unit reads, while moving in a predetermined direction, image information of a document placed on an exposure glass. The guide extends in the predetermined direction and is supported by the frame, to engage and guide the image reading unit to move the image reading unit in the predetermined direction. The biasing member biases the guide in a direction against a direction in which the guide bends due to weight of the guide and weight of the image reading unit. The adjuster adjusts a biasing force of the biasing member against the guide.

    摘要： A lens unit includes a tube lens; a single lens arranged at a downstream side with respect to the tube lens in an optical incidence direction; and a supporting member that supports the tube lens and the single lens. Reflection light from a document is condensed on an image sensor by the tube lens and the single lens to form an image. An end surface part, not facing the tube lens, of the single lens is in direct contact with the supporting member.

    摘要： A novel logic design method for avoiding wiring congestion. According to the novel logic design method, an original gate having multiple inputs coming from different directions and having multiple outputs coming to different directions can be transformed to a logic block that has an input stage and an output stage. The gates of the input stage receive signals from the multiple inputs of the original gate. The gates of the output stage send signals to the multiple outputs of the original gate. Each gate of the input stage is placed in a vicinity of its inputs. Each gate of the output stage is placed in a vicinity of its outputs. The gates of the input and output stages are functionally equivalent to the original gate.

    摘要： An image reading device that can be incorporated in an image forming apparatus includes a housing including a first housing member having a document reading area and a second housing member attached to the first housing member, a document reading unit disposed inside the housing to read a document while moving in a sub-scanning direction of the housing, a document reference line formed on the first housing member to position the document placed on the document reading area in the sub-scanning direction, and a reference position detector positioned on a plane surface of a square that extends perpendicular to the document reading area along a main scanning direction of the document reference line to detect a reference position of the document reading unit as the document reading unit moves in the sub-scanning direction.
