Abstract (en)
[origin: EP1724729A1] The device has a sensor activated during the detection of the presence of mail items passing above a set of levers (26) arranged at a determined set pitch perpendicular to a reference wall. A light intensity measurement module (42) measures a light intensity of a light ray received by a receiver, where the ray is emitted by an emitter. A processor module calculates the determined number of levers activated by the passage of the items from a comparison between the measured intensity and an initial measurement of the intensity in the absence of the passage of items. Independent claims are also included for the following: (1) a method for measuring the width of a mail item (2) a mail handling machine having a device for measuring the width of a mail item on the fly.
