Title (EN) DOWN LOADING FILM ACCESS DOOR ASSEMBLY FOR ELECTRONIC IMAGING APPARATUS
(FR) ENSEMBLE DE PORTES D'ACCES DE CHARGEMENT DE FILM PAR LE BAS POUR APPAREIL D'IMAGERIE ELECTRONIQUE
Abstract:
(EN) An electronic image printing apparatus is provided on the front face thereof with an improved downloading film access door assembly. The door assembly pivots substantially under the force of gravity from an upright closed position to an extended fully open position wherein a film cassette may be inserted into and/or withdrawn from a film cassette receiving carriage which is disposed for controlled reciprocal sliding translation during the printing process. A dashpot is provided for dampening the pivotal movement of the film loading access door so that it progressively decelerates as it approaches its open extended position so as to gradually come to a stop without substantial vibration or shock. The dashpot also includes a spring which extends through the back wall thereof to counter the increase in the weight induced opening torque as the door pivots downwardly. There is also provided a latch assembly including a pivoting lever member which is cammed by the film access door assembly to latch the film cassette receiving carriage in its initial position when the door assembly is open to inhibit accidental movement of the carriage during film cassette insertion and/or withdrawal.
(FR) Un appareil d'impression d'images électroniques comporte sur sa face avant un ensemble de portes d'accès de chargement de film par le bas. Ledit ensemble de portes pivote sous l'effet de la force de gravité d'une position droite fermée à une position étendue complètement ouverte dans laquelle on peut insérer une cassette de film dans un chariot de réception de cassette de film ou la retirer de ce dernier, lequel est disposé pour permettre un déplacement coulissant à va-et-vient pendant le procédé d'impression. On a prévu un amortisseur à fluide destiné à amortir le mouvement pivotant de la porte d'accès de chargement de film, de sorte qu'elle décélère progressivement à mesure qu'elle s'approche de sa position étendue ouverte, de manière à venir graduellement jusqu'à une butée sans vibration ou choc. Ledit amortisseur à fluide comprend également un ressort s'étendant dans sa paroi arrière, destiné à contrer l'augmentation de la force de torsion induite par le poids, à mesure que la porte pivote vers le bas. On a également prévu un ensemble de verrouillage comprenant un élément de levier pivotant, lequel est arrêté par les cames de l'ensemble de porte d'accès de film, afin de verrouiller le chariot de réception de cassette de film dans sa position initiale lorsque ledit ensemble de portes est ouvert, pour empêcher un mouvement accidentel dudit chariot pendant l'insertion et/ou le retrait de la cassette à film.
