A document acceptor (1) includes a document transport path (9) and a multi- function optical sensor (52) disposed adjacent the document path. The multi- function sensor can be operated in one of two or more modes. Depending on the mode in which the sensor is operated, signals from the sensor can be used, for example, to indicate whether a document has reached a particular position, to determine whether the document includes a predetermined pattern, such as a bar- code pattern, or to determine whether an attempt is being made to pull the document out of the acceptor.

L'invention concerne un dispositif accepteur de document (1), comprenant un chemin de transport (9) de document et un capteur optique (52) multifonctions, placé adjacent audit chemin de transport. Le capteur multifonctions peut fonctionner selon un ou plusieurs modes. En fonction du mode de fonctionnement du capteur, des signaux issus du capteur peuvent être utilisés, par exemple, pour indiquer si un document a atteint une position particulière, pour déterminer si le document comprend un motif prédéterminé tel qu'un motif de code à barres, ou pour déterminer si une tentative de retrait du document est effectuée.
