    摘要： Drive system for driving a load (20), the drive system including a motor (10) coupled to a first shaft (11), a second shaft (19) coupled to the load, and an intermediate shaft (15) coupled to the first shaft and coupled to the second shaft. The angular position of the intermediate shaft is converted by a rotational encoder (25) into a drive signal for driving the motor.

    摘要： The present invention provides a thermal printing system equipped with at least 3 light sources and 3 photodetectors positioned opposite thereto for detecting the type of dye donor element. One of said light source illuminates a dye frame whereas the other illuminate detection marks in a margin of the dye donor element. The thermal printing system according to the invention allows to distinguish between a dye donor element for color printing and black and white printing and according to an embodiment is also capable to detect further variants. The present invention further provides a dye donor element for use in such thermal printing system and to a method for detecting the type of dye donor element.

    摘要： A thermal image recording apparatus for recording an image on a recording medium has a housing and mounted within the housing a subhousing containing a thermal print head formed of a thermal printing circuit, including an array of individual activatable heating elements, and a heat sink in conductive contact with such elements for cooling the same, a blower for creating a stream of cooling air and air guides for guiding the air stream into contact with the heat sink and thence to the outside of the housing. A platen roller is in the housing for supporting the recording medium in a recording position and the subhousing is pivotally mounted in the housing to bring the print heat into and out of an operative position with the heating elements proximate to the recording medium. The subhousing has an opening in its bottom wall through which the heating elements project in exposed relation to the recording medium while the heat sink extends into the subhousing interior. The blower is situated within the subhousing and communicates via air intake and exhaust openings in another wall of the subhousing directly with the atmosphere outside the housing without significant communication with the housing interior to thereby avoid heating of the housing interior.

    摘要翻译： 一种用于在记录介质上记录图像的热图像记录装置具有壳体并且在壳体内安装包含由热敏打印电路形成的热打印头的子壳体，该热敏打印头包括单个可激活加热元件的阵列，以及导电的散热器 与这些元件接触以对其进行冷却，用于产生冷却空气流的鼓风机和用于引导空气流与散热器接触并且从而引导到壳体外部的空气引导件。 压板辊位于壳体中，用于将记录介质支撑在记录位置，并且副轴可枢转地安装在壳体中，以使打印热量进入和离开加热元件靠近记录介质的操作位置。 底座在其底壁中具有开口，通过该开口，加热元件以暴露的关系突出于记录介质，而散热片延伸到底座内部。 鼓风机位于底座内，并且通过外壳的另一壁中的进气和排气开口与壳体外部的大气直接连通，而与壳体内部没有显着的连通，从而避免了壳体内部的加热。
