Patent number: 7684091Abstract: Reference images on the respective surfaces of a reference document transported on a transportation path are read out by a first image reading section and a second image reading section, respectively. As a result a first reference readout image and a second reference readout image are acquired. in accordance with the difference between the changes in the sub-scanning direction in the first reference readout image and the changes in the sub-scanning direction in the second reference readout image, the reading cycle of the first image reading section X1 and the reading cycle of the second image reading section X2 are set. This makes it possible to equalize the magnifications of the respective images on the front and back sides of the document, even if the speeds of the document at the times of passing through readout positions for the front and back sides change over time, on account of the wear of a transportation roller.Type: GrantFiled: February 16, 2006Date of Patent: March 23, 2010Assignee: Sharp Kabushiki KaishaInventors: Sohichi Takata, Yoshitaka Okahashi, Kohsuke Harada, Takao Horiuchi, Kenji Tanaka, Kouji Yamaji

Patent number: 7106942Abstract: A set pattern image with no displacement is recorded onto recording paper. In this set pattern image, the centers of auxiliary patterns are displaced in an auxiliary scan direction off a referential straight line passing through the centers of primary patterns. The image forming apparatus causes the set pattern image to be read, measures the displacements of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and compensates for the displacements, such as by adjusting writing timings in the auxiliary scan direction so that the displacements become zero.Type: GrantFiled: April 26, 2001Date of Patent: September 12, 2006Assignee: Sharp Kabushiki KaishaInventors: Kyosuke Taka, Shoichi Fukutome, Kazunobu Takahashi, Hidekazu Sakagami, Takao Horiuchi, Yoshitaka Okahashi
