Abstract
(EN)
The invention relates to a method and an apparatus for feeding image plates (1) used in intraoral dental X-ray photography into a reading device. During the reading step an excited phosphorus layer on the plate (1) is scanned with a laser beam and is converted into a visible image on a display screen or a film. In accordance with the invention, the excited image plates (1) are removed from their protective bags and are stacked into a housing (2) which acts as their intermediate storage and is protected from light, from where the plates are gripped by a conveyor, such as a toothed belt (16), to be fed forwards. The plates can be pulled or pressed e.g. by a magnet (12) and/or a pushing device (15) towards a conveyor conducted laterally of the housing. The conveyor (9) may comprise gripping means (16), with which the conveyor entrains the image plate which is closest each time and moves it forward on the transfer path onto the path of the slide integrated in the reading device. The slide grips the plate which gets within its reach each time and transfers it to the reading step for the image to be read and the plate to be cleared. The slide may make a reciprocating movement so as to return the plates which have been read onto the conveyor (9), which then also carries out removal of the plates.

L'invention concerne un procédé et un appareil d'acheminement dans un dispositif de lecture de plaques images (1) utilisées dans un radiogramme buccal. En cours de lecture, une couche phosphorée excitée reposant sur la plaque (1) est scannée avec un faisceau laser et transformée en image visible sur un écran d'affichage ou un film. Selon l'invention, les plaques images excitées (1) sont retirées de leurs sachets protecteurs et empilées dans un boîtier (2) servant de stockage intermédiaire et les protégeant de la lumière. De là les plaques sont saisies par un transporteur, tel qu'une bande crantée (16), pour être acheminées vers l'avant et attirées ou poussées par un aimant (12) et/ou un dispositif de pousse (15) vers un transporteur bifurquant sur le côté par rapport au boîtier. Le transporteur (9) comprend des moyens de préhension (16) permettant d'entraîner la plaque image qui se rapproche et défile vers l'avant sur le chemin de transfert le long du guide intégré dans le dispositif de lecture. Ce guide saisit la plaque qui est à sa portée et la transfère de manière que l'image soit lue et la plaque éliminée. Le guide peut suivre un mouvement de va-et-vient de manière à retourner les plaques lues sur le transporteur (9) destiné à éliminer lesdites plaques.
