Abstract

La présente invention concerne un appareil et un procédé pour détecter un billet de banque collé par ruban adhésif (billet ou effet en devise) utilisant des ondes ultrasonores à mettre en œuvre dans des guichets automatiques bancaires y compris des compteuses de billets, scanners de billets, distributeurs de billets, BRM (machines à recycler les billets), CRM (machines à recycler les espèces). En particulier, la présente invention peut être utilisée de manière avantageuse pour trier des billets de banque mutilés, comme un billet de banque déchiré ou réparé qui est joint par ruban adhésif, dans tout type de guichets automatiques bancaires munis d'un dispositif d'alimentation par cassette pour transporter un nombre de feuilles de billets individuellement une par une dans la machine et une section de séparation servant à détecter les types et les conditions des billets transportés. Étant donné que la présente invention fait usage d'ondes ultrasonores, pas d'une structure mécanique comme dans la technique connexe, les billets de banque mutilés collés par ruban adhésif sont détectés avec une précision plus élevée.
