    Abstract: Bei einer bekannten optischen Abtasteinrichtung ist ein Abtastschlitten mit einer zeilenförmigen Lichtempfangs­einrichtung unterhalb einer transparenten Auflageplatte für die zeilenweise abzutastende Vorlage auf Führungselementen in Form von parallelen Rundstangen verfahrbar gelagert. Zur Erzielung einer hohen Abtastgenauigkeit soll die neue Abtasteinrichtung während der Verfahrbewegung des Abtastschlittens einen gleich­bleibend genauen Abstand zwischen der Lichtempfangseinrichtung und der abzutastenden Vorlage gewährleisten.
    Dies wird dadurch erreicht, daß beide Führungselemente jeweils als Gestellteil (1, 2) mit einer Führungsbahn (5 bzw. 6) als Auflage für den Abtastschlitten (7) und mit zumindest einer der Führungsbahn (5 bzw. 6) zugewandten Anlagefläche (34 bzw. 35) ausgebildet sind, an der die Auflageplatte (14) mit ihrer Auflagefläche (16) für die Vorlage (15) angedrückt wird.
    Die neue Abtasteinrichtung findet vorzugsweise als Flachbettscanner Verwendung, bei dem ein optoelektronischer Zeilensensor als Lichtempfangseinrichtung unmittelbar unter der abzutastenden Vorlage quer zur Zeilenrichtung bewegt wird.

    Abstract: An optical unit (70) of an image reading device (6) has the center of gravity in a position toward a first sub scanning direction, relative to the middle point of the optical unit (70) in terms of sub scanning directions. An engagement part (63a) is provided in a position toward a first main scanning direction relative to a sliding part (65b). A plurality of pairs of pinching parts (65c) include a first pair provided in a position toward the first sub scanning direction and a second pair provided in a position toward a second sub scanning direction. Of the two pinching parts (65c) in the second pair, the pinching part (65c) provided in a position toward the first main scanning direction is biased by a first biasing member (69) toward a rail part (80) side, and the pinching part (65c) provided in a position toward a second main scanning direction is not biased by the first biasing member (69).

    Abstract: A reading apparatus includes a reading unit and a shaft along which the reading unit slides. The reading unit includes a reading portion for reading an image, a holding portion that holds the reading portion. The holding portion has a first surface. The reading unit further includes a sliding portion that moves in contact with the shaft. The sliding portion has a second surface facing the first surface. A first region is provided between the first surface of the holding portion and the second surface of the sliding portion so as to form a predetermined gap which reduces the transmission of vibrations from the shaft to the reading unit.
