CA 2479844

There is provided an image reading apparatus which reads an image pattern of a medium placed on a detection surface of a sensor array (100). In a waiting state, electrical connection between the sensor array (100) and a drive controller (110, 120) is cut off, and whether a medium is placed on the detection surface or not is detected. When a medium is placed on the detection surface, the sensor array (100) and the drive controller (110, 120) are electrically connected and an image reading operation is started. In a case where the medium is separated from the detection surface during the image reading operation, the image reading operation is suspended and the image reading apparatus is set to the waiting state.

Cette invention se rapporte à un appareil de lecture d'images, qui permet de lire un motif d'image d'un support placé sur une surface de détection d'un réseau de capteurs (100). En position d'attente, la connexion électrique entre le réseau de capteurs (100) et un contrôleur d'attaque (110, 120) est coupée, et l'appareil détecte la présence d'un support placé sur la surface de détection. Lorsqu'un support est placé sur la surface de détection, le réseau de capteur (100) et le contrôleur d'attaque (110, 120) sont connectés électriquement et une opération de lecture d'images démarre. Dans les cas où le support est séparé de la surface de détection pendant l'opération de lecture d'images, l'opération de lecture d'images est suspendue et l'appareil de lecture d'images est placé en position d'attente.
