摘要： A thermal transfer printer has a platen and a thermal head between which are pinched a transfer paper sheet and an ink film, so that the ink is transferred from the ink film to the transfer paper sheet as heat is applied to the transfer paper sheet by the thermal head. The film is supplied by a supply roll and is taken-up by a take-up roll. The thermal head is swingable between a position where it contracts the platen and a position away from the platen. When the thermal head is in the position away from the platen, the distance therebetween is greater than the maximum diameter of the supply roll. A film drum can hold a plurality of films each being constituted by the supply roll and the take-up roll. Swing arms are provided for demounting the supply roll of a selected film from the film drum and for bringing the same to a position away from the film drum, and also for returning the same from this position to the film drum. During the movement of the supply roll between the position in the film drum and the position away from this position, the thermal head is moved away from the platen so as not to hinder the movement of the supply roll.
摘要翻译： 热转印打印机具有压板和热敏头，两者之间夹有转印纸和油墨膜，使得油墨从转印纸张转印到转印纸上 热头。 胶片由供应辊供应并被卷取辊卷取。 热敏头可在其收缩压板的位置和远离压板的位置之间摆动。 当热敏头位于远离压板的位置时，它们之间的距离大于供给辊的最大直径。 薄膜滚筒可以容纳由供给辊和卷取辊构成的多个薄膜。 提供摆动臂用于从胶卷鼓上拆下所选胶片的供应卷，并将其提供到远离胶卷鼓的位置，并将其从该位置返回到胶卷鼓。 在供给辊在胶片卷筒的位置与远离该位置的位置之间运动期间，热敏头远离压板移动，以免阻碍供纸辊的移动。
