Abstract: An image reading apparatus includes a document table, a reading device, a communication line, a rail, and a transport mechanism. On the document table, a document is placed. The reading device reads the document placed on the document table, and outputs image data. The communication line is configured to electrically transmit the image data. The rail extends along a reading direction in which the reading device reads the document placed on the document table, the communication line being fixed to the rail. The transport mechanism transports the reading device along the rail, thereby transporting the reading device along a reading route through which the reading device reads the document placed on the document table. The transport mechanism electrically connects the reading device to the communication line.

Abstract: A first reference portion has a lower surface of a first color. A second reference portion is adjacent to the first reference portion in a first direction and has a lower surface of a second color. A data processing portion executes a color determination process of determining whether one or more reference pixel data of a reference area in line image data is data of the first color or the second color. A control device sequentially selects a plurality of drive operations from a plurality of trial drive operations and causes the unit drive device to execute the plurality of drive operations, thereby positioning a scanning unit at a home position. When causing the unit drive device to execute the plurality of drive operations, the control device outputs, to the unit drive device, a speed command signal of a different level according to a moving distance of the scanning unit.

Abstract: An image scanning device includes a transport section that transports a document along a transport path; an image scanning unit that is configured to scan an image from the document transported by the transport section; and a first conductive section that is configured to electrically conduct with the image scanning unit. The image scanning unit has a scanning section that is configured to scan the image from the document transported by the transport section, a glass plate that is configured to contact with the document between the scanning section and the transport path, and a second conductive section that is configured to electrically conduct with the glass plate. The image scanning unit is configured to displace along a displacement direction that intersects the transport path. The first conductive section is configured to follow the displacement of the image scanning unit and to maintain electrical conductivity with the glass plate by maintaining a state where the first conductive section is in contact with the second conductive section by following the displacement of the image scanning unit.
