Abstract:
1. A recording medium placement device comprising: a placement unit in which a recording medium is placed; a guide member provided on the placement unit and along an edge of the recording medium placed on the placement unit and movable in a first direction orthogonal to the edge so that the guide member approaches the recording medium and in a second direction opposite to the first direction, the edge being at a first position; a distance detection unit that detects a distance between the guide member and the edge of the recording medium; a drive unit that moves the guide member in the first direction until the distance detection unit detects that the guide member contacts the recording medium, then stops and moves the guide member in the second direction, then stops the guide member a second time; a gap length calculation unit that calculates a length of a gap between the recording medium and the guide member when a movement of the guide member is stopped the second time using a detection output from the distance detection unit; and an adjustment unit that moves the guide member to the edge of the recording medium at the first position based on the length of the gap calculated by the gap length calculation unit.
