A device for detecting shortage of cigarette packs in a carton (C0)) has a pair of first proximity sensors (28) capable of individually detecting the cigarette packs (CP) at the opposite ends of the carton (C0) in an inspecting position, among other cigarette packs (CP) in the carton (C0), and a plurality of second proximity sensors (32) capable of individually detecting the remaining cigarette packs (CP) in the carton (C0) in the inspecting position, the interval (X) between each two adjacent second proximity sensors (32) being longer than the width (Y) of each cigarette pack (CP). <IMAGE> |
