<p>An apparatus for detecting a position in a widthwise direction (W) perpendicularly intersecting a direction of feeding (C) of an article such as a packaging film (F), which is provided with a light receiving means (30) for detecting an edge (Ma) in the widthwise direction (W) of a cut mark (M) attached to an edge (45) of the film or the film (F). On this light receiving means (30), a plurality of light receiving elements (S1 ... Sn) are arranged in a row in the widthwise direction (W), the row of the light receiving elements (S1 ... Sn) are arranged to extend across the edge (45, Ma). Because light receiving elements (S1 ... Sn) such as solid image sensing devices are arranged at a small pitch, a detecting accuracy can be improved.</p> |
