Abstract

Le problème décrit par la présente invention est de fournir un dispositif de détection d'article pour un distributeur automatique d'articles, qui peut détecter avec précision un article stocké sur un rayon. À cet effet, l'invention porte sur un dispositif de détection de rupture de stock (dispositif de détection d'article) pour un distributeur automatique d'articles, ledit dispositif comprenant : un mécanisme de sortie (55) qui est disposé sur un rayon (13) stockant des articles placés côte à côte dans une direction avant-arrière, et fait sortir séquentiellement des articles sur le côté avant sur la base d'une instruction de vente ; et une unité de détection (80) qui est installée au niveau d'une partie d'extrémité avant du mécanisme de sortie pour pouvoir se déplacer dans une position avant-arrière et détecte si un article est placé au niveau de la partie d'extrémité avant. Lorsque l'unité de détection détecte que l'article n'est pas placé au niveau de la partie d'extrémité avant du mécanisme de sortie (55) pendant une période prédéterminée, une unité de détermination détermine que l'article est en rupture de stock dans le mécanisme de sortie (55).
