摘要： A thermal color printer includes a reversible platen roller 9 and associated pinch rollers 11, 10 on the paper feed and discharge sides. The paper is repeatedly advanced back and forth through the printing station to successively print the different color separations. The discharge side pinch roller 10 is coupled to the platen roller by "unequal" spur gear 31, 32 and one-way clutches 33 such that it is frictionally driven by the platen roller in the sheet advance direction and gear driven by and at a slower speed than the platen roller in the reverse or sheet return direction. This serves to tension the sheet of paper during each return conveyance to thus maintain it in tight contact and registration with the platen roller, thereby avoiding offsets between the successive color separation printings and attendant fringe patterns.

摘要： A shell-type printing apparatus is equipped with a link mechanism for loading and unloading an inksheet cassette from the printing apparatus. The link mechanism comprises a support frame which supports an inksheet cassette and two pairs of links which have one end pivotably mounted on the base of the printing apparatus and the other end pivotably connected to the support frame. The link mechanism rotates the support frame between a first and a second position. In the first position, the support frame is disposed above and to the front of the base of the printing apparatus so that an inksheet cassette can be mounted on the support frame. In the second position, the support frame is disposed inside the base and the inksheet cassette is disposed in the proper position for printing.
摘要翻译：壳式打印装置配备有用于从打印装置装载和卸载墨盒盒的连杆机构。连杆机构包括一个支撑框架，支撑框架支撑一个墨水盒式磁带和两对连杆，其中一对可枢转地安装在打印设备的基座上，另一端可枢转地连接到支撑框架上。连杆机构使支撑框架在第一和第二位置之间旋转。在第一位置，支撑框架设置在打印设备的基座的上方和下方，使得墨盒可以安装在支撑框架上。在第二位置，支撑框架设置在基座内部，并且墨水盒带被设置在用于打印的适当位置。

摘要： A thermal transfer printer employs a relatively small diameter platen roller 20 flanked by a pair of sprockets 3c which support endless timing belts 2. A clamp 7' for gripping the leading edge of a sheet 6 to be printed is mounted laterally across and between the belts. The attendantly small radius of curvature of the roller at the printing station prevents any contact by components and structure mounted to the reciprocable printing head 1.

摘要： A device for cooling a thermal head of a thermal image recording apparatus comprising a ventilation unit for producing a stream of air for cooling the thermal head and a duct for guiding the stream of air having cooled the thermal head outside the recording apparatus. The air heated by having cooled the thermal head does not circulate within the recording apparatus, whereby the temperature within the recording apparatus can be prevented from rising.
