Patent ID: 8770879

Claim:
A recording apparatus comprising: a recording section configured to record an image on a recording medium; an endless conveying belt having a surface disposed in confrontation with the recording section and configured to move in a conveying direction with the recording medium supported by the surface, thereby conveying the recording medium in the conveying direction; a measuring section having a detecting region and configured to measure a position of the conveying belt with respect to a perpendicular direction that is perpendicular to the conveying direction, the measuring section comprising an optical sensor that is configured to detect the position of the conveying belt with respect to the perpendicular direction; and a sensor moving section configured to move the sensor based on a measurement result of the measuring section, such that the conveying belt is detected in the detecting region, wherein the sensor moving section is configured to move the sensor linearly in a direction intersecting the conveying direction, wherein the detecting region includes a plurality of divisional detecting regions arranged in the perpendicular direction, the plurality of divisional detecting regions having a first end side and a second end side, wherein the measuring section is configured to measure the position of the conveying belt with respect to the perpendicular direction, based on at which of the plurality of divisional detecting regions one end portion of the conveying belt in the perpendicular direction is located, wherein the sensor moving section comprises a velocity determining section that is configured to determine a moving velocity of the sensor, the sensor moving section being configured to move the sensor at the moving velocity determined by the velocity determining section, and wherein the velocity determining section is configured, when a detection state of the conveying belt has changed at the first end side, to change the moving velocity of the sensor such that the moving velocity increases in a first-end direction that is a direction from the second end side toward the first end side.
