The several positions (10) describe a two-dimensional positioning system. Each position has a control component for controlling the placing of the several articles (8). Each individual position is provided with at least one of the several detectors which records both the presence and absence of one of the several articles in the position in question. - All the several articles are exposed visibly from the front side of the device (1). Each position is limited at least at the bottom against a locating surface for the articles and at the rear with a rear wall. It is accessible from the front for both insertion of new articles and for removal of articles. The detectors can detect the reflection from the surface in that of an article. The detectors are infra-red sensors. |
