Abstract

L'invention concerne un dispositif d'impression par transfert thermique qui utilise du papier de réception d'image enroulé mais peut également changer facilement de type de papier de réception d'image utilisé. Le dispositif d'impression par transfert thermique comprend : une unité d'alimentation en papier enroulé qui fait tourner un premier papier de réception d'image enroulé et sort et s'enroule dans le premier papier de réception d'image ; une unité d'impression qui chauffe une feuille de transfert thermique, transfère un matériau coloré de la feuille de transfert thermique au premier papier de réception d'image, et forme une image ; un dispositif de découpe qui découpe le premier papier de réception d'image ayant l'image formée sur ce dernier, en une taille prescrite, et crée un matériau imprimé ; et un orifice d'évacuation de papier qui évacue le matériau imprimé. Une cassette logeant un type feuille-papier de second papier de réception d'image peut être fixée à ce dispositif d'impression par transfert thermique ou détachée de dernier. Le groupe d'impression forme une image sur le second papier de réception d'image alimenté à partir de la cassette. Le second papier de réception d'image ayant l'image formée sur ce dernier est évacué à partir de l'orifice d'évacuation de papier.
