Method and recording apparatus for detecting rear edge of a recording medium

A recording apparatus configured to detect a rear edge of a recording medium, the apparatus comprising:

• a conveyor arranged to convey the recording medium to a recording means;
• a conveying quantity detector arranged to detect conveying quantity data of the recording medium at a predetermined interval;
• a memory arranged to receive and store the conveying quantity data;
• a passage detection lever arranged upstream of the recording means and configured to swing upon passage of the rear edge of the recording medium;
• a detection sensor positioned to detect the swinging movement of the passage detection lever;
• and
• a controller for calculating a conveyance distance of the recording medium based on a past data point of the stored data selected in accordance with a physical returning time starting from a point of time when the rear edge of the recording means passes the passage detection lever and causes the swinging of the passage detection lever to a point of time when the detection sensor detects the swinging movement.
