    • In a printer for printing on a recording medium using a transfer medium, a transfer medium capable of being repeatedly used at the same portion thereof (e.g., a multi-pass thermal transfer ribbon) is conveyed in the normal direction in performing the printing process by a recording means such as a thermal head etc. and the conveying amount of the transfer medium which is used for printing is measured at that time. The transfer medium is conveyed in the reverse direction by a given amount based on the result of the measurement and the reverse direction conveying ratio of the transfer medium to the used length of the transfer medium which is arbitrarily set by a transfer medium reverse direction conveying ratio setting means irrespective of the used amount of the transfer medium every time a unit of printing is completed. Thereafter the transfer medium is conveyed in the normal direction for printing. Repeating these processes, it is possible to use up the transfer medium so far as it is can be practically used for printing.
    • 在用于在使用转印介质的记录介质上打印的打印机中,可以在执行打印处理时在正常方向上传送能够在其相同部分重复使用的转印介质(例如,多遍热转印色带) 此时测量用于打印的传送介质的传送量等热敏头等记录装置。 转印介质基于转印介质逆向传送比任意设定的转印介质的测量结果和转印介质的使用长度的反向传送率,反向传送给定量 每当打印单元完成时,与传送介质的使用量无关的设定装置。 此后,转印介质沿正常方向输送以进行印刷。 重复这些处理,可以使用转印介质,只要它实际上可用于印刷。

    • A line-type thermal printing apparatus includes a thermal head for recording on a sheet whose thickness is even in the feeding direction thereof and uneven in the print line direction. The apparatus also includes a platen having a platen body portion that rotates integrally with a platen shaft and that feeds the sheet by pinching a part of the sheet between the thermal head and the platen body portion, and separate platen portion that face other parts of the sheet which have thicknesses different from that of the part of the sheet pinched between the thermal head and the platen body portion. The separate platen portions have center holes that are dimensioned to loosely fit the platen shaft. Urging mechanisms are provided for urging the separate platen portions so as to press the other parts of the sheet against the thermal head. For example, a part of a sheet is located opposite to the platen body portion and the other parts of the sheet are located opposite to the separate platen portions. While the part of the sheet is pressed against the platen body portion, the separate platen portions are urged by the urging mechanisms so as to press the other parts of the sheet against the thermal head. The sheet is fed by rotating the platen body portion while recording is sequentially performed by the thermal head.
    • 线型热敏打印设备包括:热敏头,用于在厚度均匀的纸张的进纸方向上记录并且在打印行方向上不均匀地记录。 该设备还包括具有压板主体部分的台板,该压板主体部分与压板轴一体地旋转,并且通过将片材的一部分夹在热敏头和压板主体部分之间而进给纸张,以及分离的压板部分, 片材的厚度不同于夹在热敏头和压板主体部分之间的片材的部分的厚度。 单独的压板部分具有中心孔,该中心孔的尺寸适于松动地装配压板轴。 提供推动机构以促使单独的压板部分将片材的其他部分压靠在热敏头上。 例如,片材的一部分位于与压板本体部分相对的位置,并且片材的其它部分位于与分开的压板部分相对的位置。 当片材的一部分被压靠在压板本体部分上时,分离的压板部分被推动机构推动,以将片材的其他部分压靠在热敏头上。 在通过热头依次执行记录的同时通过旋转压板本体部分来供纸。
