Abstract: A vehicle-mounted relay device includes a relay unit configured to perform relay processing of transmitting each of a plurality of frames received from a corresponding one of a plurality of vehicle-mounted devices to a corresponding one of the plurality of vehicle-mounted devices serving as destinations, a determination unit configured to determine that the plurality of frames include a start-request for starting a session of communication between the plurality of vehicle-mounted devices and that the plurality of frames include a start-response to the start-request, a generation unit configured to generate, on a session-by-session basis, a common key to be used in the session attended by, among the plurality of vehicle-mounted devices, a vehicle-mounted device serving as a source of the frame determined to include the start-request by the determination unit and one or more vehicle-mounted devices serving as a source of the frame, and a transmission unit.

Abstract: A document reading apparatus including: a first scanning section that moves in a scanning direction along a document surface, for supporting a first mirror to reflect an image of a document in a direction parallel to the scanning direction; an intermediate scanning section that moves synchronous with the first scanning section, for supporting an intermediate mirror to reflect the image of the document reflected by the first mirror in a direction opposite from an incident direction of the image; a reading section including an imaging sensor for reading the image of a scanned document and a focusing lens for focusing the image of the document reflected by the intermediate mirror on the imaging sensor; a driving wire for pulling the first scanning section in the scanning direction; a supporting pulley for supporting the driving wire at a starting side for scanning or at an ending side for scanning; a position adjustment section capable of adjusting a position of the supporting pulley in its axial direction; a co
