Title
(EN) MEDIA SCANNER
(FR) SCANNER DE SUPPORTS
Abstract
(EN) A media scanner including an input tray, an output tray disposed above the input tray, a media feeder to advance media along a media path from the input tray to the output tray, an upper scanning device to generate a first scan line, and a lower scanning assembly. The upper scanning device is disposed to face downward to scan a first side of the media. The lower scanning assembly is disposed to face upward to scan a second side of the media. The media path extends from the input tray to below the upper scanning device, to above the lower scanning assembly, and to the output tray. The upper scanning device is disposed at an angle with respect to the media path to cause a front edge of the media advancing along the media path to contact the upper scanning device at or before the first scan line.
(FR) La présente invention concerne un scanner de supports comprenant un plateau d'entrée, un plateau de sortie disposé au-dessus du plateau d'entrée, un dispositif d'alimentation en médias pour faire avancer les supports le long d'un chemin de médias du plateau d'entrée au plateau de sortie, un dispositif de balayage supérieur pour générer une première ligne de balayage, et un ensemble de balayage inférieur. Le dispositif de scanner supérieur est disposé de manière à être orienté vers le bas pour scanner une première face du support. L'ensemble de scanner inférieur est disposé de façon à être tourné vers le haut pour scanner un second côté du support. Le trajet du support s'étend du plateau d'entrée au plateau de sortie en passant par le dessous du dispositif de scanner supérieur et le dessus du dispositif de scanner inférieur. Le dispositif de scanner supérieur est disposé à un angle par rapport au chemin du support pour qu'un bord avant du support avançant le long du chemin du support entre en contact avec le dispositif de scanner supérieur à la première ligne de balayage ou avant celle-ci.
