Title
(EN) PRINTER
(FR) IMPRIMANTE
Abstract
(EN) A printer includes a supply shaft wound with unused film including contrast agent, a winding shaft wound with used film including used contrast agent, rotation-speed detector for detecting a rotation speed of the supply shaft, and remaining-amount detector for determining an amount of unused film from the detected rotation speed detected. In the printer, the remaining amount of unused film such as ink film, roll paper or the like can be determined accurately.
(FR) Cette invention se rapporte à une imprimante, qui comprend une broche d'alimentation sur laquelle est enroulé un film non utilisé contenant l'agent de contraste, une broche d'enroulement sur laquelle est enroulé le film utilisé contenant l'agent de contraste utilisé, un détecteur de vitesse de rotation servant à détecter la vitesse de rotation de la broche d'alimentation, et un détecteur de quantité restante servant à déterminer la quantité de film non utilisé sur la base de la vitesse de rotation détectée. Ainsi, la quantité restante de film non utilisé, tel que film d'encre, papier en rouleaux ou similaire, peut être déterminée avec précision dans cette imprimante.
