Abstract: In an image reading apparatus (1), a plurality of reading sensors (9. 11) extend in a main scanning direction and separated from each other in the main scanning direction so as to be located in a staggered arrangement in which a part of one of the reading sensors (9. 11) in the longitudinal direction faces a part of adjacent one of the reading sensors in a subscanning direction. A first connection member (25) is provided to the part of one of the reading sensors facing the part of the adjacent one of the reading sensors. The first connection member (25) protrudes toward the adjacent one of the reading sensors. A second connection member (27) is provided to the part of the adjacent one of the reading sensors facing the part of the one of the reading sensors. The second connection member (27) protrudes toward the one of the reading sensors. The first and second connection members are brought into contact with each other by being urged by a spring (29).

Abstract: Die Erfindung betrifft ein Verfahren zur Messung der Längenänderung einer Vorschubspindel (13) in einem Druckvorlagenbelichter, wobei der Belichter mit mindestens einem Belichtungskopf (11) ein Aufzeichnungsmaterial belichtet, das auf eine Belichtungstrommel (1) gespannt ist. Die Belichtungsköpfe (11) befinden sich auf einem Belichtungskopfträger (16), der mittels eines Schrittmotors und der Vorschubspindel (13) in einer Vorschubrichtung axial an der Belichtungstrommel (1) entlang bewegt wird. Die Messung erfolgt, indem die Zahl (M 0 ; M x ) der Schrittmotortakte bestimmt wird, die der Belichtungskopfträger (16) zum Durchfahren einer zur Vorschubrichtung parallelen Referenzstrecke (35) benötigt. Während einer Kalibrierungsphase wird eine optimale Zahl (K 0 ) von Schrittmotortakten je Umdrehung der Belichtungstrommel (1) eingestellt, und die Zahl (M 0 ) der Schrittmotortakte wird bestimmt, die zum Durchfahren der Referenzstrecke (35) benötigt werden. Während einer Betriebsphase wird die Zahl (M x ) der Schrittmotortakte bestimmt, die zum Durchfahren der Referenzstrecke (35) benötigt werden, und eine korrigierte Zahl (K k ) von Schrittmotortakten je Umdrehung der Belichtungstrommel (1) wird nach der Beziehung K k = K 0 × M x / M 0 bestimmt. Durch ein Temperierungssystem wird die Temperatur der an der Messung beteiligten Bauelemente konstant gehalten.

Abstract: An optical adjustment arrangement for a scanning system comprises a main part (21;22) having defined thereon a triangle with a center point (29; 32) and first and second base points (27, 28; 30, 31). An optical part (23; 24) is positioned onto the main part (21; 22) so that the center point (29; 32) is aligned with the optical axis (50) of the optical part. The right and left sides of the optical part (23; 24) are adjusted separately and independently by first and second adjustment means (51, 52; 53, 54). The position of the adjustment means (51, 52; 53, 54) coincides with the base points of the triangle (27, 28; 30, 31). When one of the first and second adjustment means (51, 52; 53, 54) is moved in a direction perpendicular to the plane defining the triangle, the main part (21; 22) with the optical part (23; 24) is rotated around the line connecting the other of the first and second base points (27, 28; 30, 31) with the center point (29; 32). Stabilising parts (25; 26) acting as flexible hinges are preferably provided around the main part (21; 22).

Abstract: PCT No. PCT/US92/04734 Sec. 371 Date Feb. 2, 1994 Sec. 102(e) Date Feb. 2, 1994 PCT Filed Jun. 5, 1992 PCT Pub. No. WO92/22109 PCT Pub. Date Dec. 10, 1992A laser beam scanning apparatus employs a movable reflector (32) having a large number of flat reflective sides (44) a deflector (16) which shifts the laser beam (10) at high speed across a plurality of the reflective sides (44). The movement of reflector (32) is synchronized with the deflection of the laser beam (10) to produce a desired scan pattern in a first scan direction (X). The reflective sides (44) of the movable reflector (32) may be angled relative to each other in a second direction (Y) to produce different scan lines thereby providing an X-Y scan pattern. The combined high speed beam deflection and motion of the reflector (32) provide scanning of the beam (10) in parallel scan segments thereby providing high scanning speed of the beam with a high degree of resolution.
