摘要： For an electro-thermal printer of the kind that uses a ribbon having a central conducting layer that is covered on one surface by a resistive layer that receives electrical printing currents and on the other surface by a thermally transferrable ink layer, printing current is collected from the conducting layer by an electrically conducting contactor at the ink layer surface of the ribbon. Such contact through the ink layer occurs on the takeup side of a printhead where the integrity of the ink layer is not of concern and voids in the ink layer occur as a result of ink transfers for printing. To increase the quality of the electrical connection, projecting points or barbs may be included on said contactor to penetrate to the conducting layer through intact portions of ink layer.

摘要： A printhead assembly for a typewriter of the kind that swipes a printhead along a ribbon in producing marks on a receiving medium, is mounted to pivot and includes a ribbon guide that serves to wrap the ribbon around the trailing side (for a forward printing direction) of the printhead. The assembly is positioned to permit the printhead to be rotated to a normal printing position at a printing line. By so arranging the ribbon path that the ribbon directions for arrival and departure of the assembly intersect the pivot axis, essentially zero resultant torque may be applied to the assembly by ribbon tension forces and the printing pressure at the receiving medium is, accordingly, unaffected by ribbon tension variations.

摘要： The conductive film (3) of a compliant doctor blade has dispersed particles of molybdenum disulfide, as well as dispersed particles of grit and conductive filler. The molybdenum disulfide eliminates filming of toner. The molybdenum disulfide may be a surface powder since the anti-film action occurs at the pre-nip and therefore is not lost by the molybdenum disulfide wearing away at the nip.
摘要翻译：柔性刮刀的导电膜（3）具有分散的二硫化钼颗粒，以及分散的砂粒和导电填料颗粒。二硫化钼消除了调色剂的成膜。二硫化钼可以是表面粉末，因为防粘膜作用发生在预压区处，因此在二辊磨损时不会损失二硫化钼。

摘要： A developer apparatus (29) for use in an electrostatic reproduction apparatus includes a large reservoir of toner (34, 44). The toner is located in a supply chamber (39) and is metered to a developer roller chamber (35) from which it is carried by a developer roller (31) past a doctor blade (36) to a photoconductor drum (19) for image development. A toner metering roller (41) rotates with the developer roller (31) to provide a continuous supply of toner from the supply chamber (39) to the developer chamber (35). Once an equilibrium level (65) is reached, the toner metering roller (41) acts to remove toner (34) from the developer chamber (35) to the supply chamber (39) to insure proper operation of the developer roller (31).

摘要： Member (9) has a tension arm (13) over which ribbon (3) feeds. Biasing arm (17) presses member (9) toward brake surface (7), with slot (21) moved until it encounters stud (23). At low tension of ribbon (3), brake surfaces (11) and (7) press and hold ribbon (3). As feed tension increases tension arm (13) forces member (9) back until stud (23) encounters the opposite end of slot (21), after which slightly higher force further opens the brake and arm (13) continues to provide feed tension. The mechanism is small, efficient, smooth functioning, and suited to incorporation as part of a ribbon cartridge.

摘要： A ribbon loading system for a printer utilizes a ribbon cartridge that includes a container enclosing two coaxially arranged ribbon reels. By providing flexible blades in the floor of the container, the reels are urged toward a top cover where relative movement is restrained. Upon loading of the cartridge, camming arms enter apertures in the container and are moveable to a clamping position to draw the blades from the ribbon reels and allow free rotational movement.For a presently preferred implementation, the structure including the camming arms is coupled through linkages to clear the ribbon threading path and thereby facilitate ribbon insertion.

摘要： A ribbon feed system for a matrix printer utilizes metering rollers located on the printhead carrier to maintain a substantially zero ribbon velocity relative to the receiving medium with an on-carrier ribbon feed. By coordinating roller rotation with carrier motion, relative motion that would tend to cause smearing during mark formation is avoided. For printers that inject current into the ribbon to cause printing, friction drag is reduced and tension control is simplified by collecting current at the metering rollers for return to the printhead energizing circuitry. Such dual use of the metering rollers takes advantage of the firm intimate contact that exists for metering to establish a high quality electrical connection. A tension controlled brake at the ribbon supply serves to assure tensions are held within a narrow range at the printhead with such a ribbon metering system.
摘要翻译：用于矩阵式打印机的色带供给系统使用位于打印头托架上的计量辊，以相对于接收介质保持基本上为零的色带速度，带有载带上色带进纸。通过协调滚子旋转与载体运动，避免了在标记形成期间倾向于引起拖尾的相对运动。对于将电流注入色带进行打印的打印机，通过收集计量辊上的电流以便返回到打印头通电电路，可以减少摩擦阻力并简化张力控制。计量辊的这种双重使用利用了存在用于计量以建立高质量电连接的牢固的紧密接触。色带供应器处的张力控制制动器用于通过这种色带计量系统确保在打印头处的紧张度保持在窄范围内。

摘要： In thermal printing the guide (29) positionable toward the platen (3) on a pivoted arm (50) during lift-off correction allows a bond for correction to set before the ribbon (22) is pulled away. The ribbon (22) has an outer layer which adheres to printed characters at somewhat elevated temperatures but is non-tacky at room temperatures. Thermal printing is conducted by setting the switch (44) for heating to temperatures higher than the lift-off temperature.

摘要： A thermal printhead, which is pivotally mounted on a carrier, is moved into and out of its printing position by a four bar linkage, which is responsive to the direction in which the carrier is being advanced, rendering a spring, which urges the thermal printhead into its printing position, effective and ineffective. When the carrier is advanced from left to right to print, the linkage responds to a drive mechanism for the carrier to enable movement of the printhead into its printing position by the spring prior to the carrier drive mechanism moving the carrier. When the carrier is to be moved from right to left in the non-printing direction, the linkage responds to the initial motion of the carrier drive mechanism in this direction to render the spring ineffective and to move the printhead out of its printing position prior to the carrier drive mechanism moving the carrier.

摘要： Wear on the elements (5) of a printhead (3) is spread by shifting the region of use of the printhead line by line. Font (13) provides information as to whether any character in a line employs the upper three pels or the bottom three pels of a line. For each line which can be printed from different shift positions of the printhead, selection logic controls paper feed (15) to index platen (9) to the least used of a shifted position of printhead. Only those electrodes over the print line in each shifted position are used for printing. This distributes wear without requiring any special ribbon feed. The three pel height is at least as wide as the serifs on most characters, which avoids some electrodes being used for the serifs of given characters in more than one shift position.
摘要翻译：通过逐行移动打印头的使用区域来扩展打印头（3）的元件（5）上的磨损。字体（13）提供关于一行中的任何字符是否采用一行的上三个像素或三个三像素的信息。对于可以从打印头的不同移位位置打印的每条线，选择逻辑控制供纸（15）以将压板（9）分度至最少使用打印头的偏移位置。只有在每个移位位置的打印线上的那些电极才能用于打印。这不需要任何特殊的丝带进给，从而分配磨损。三个像素高度至少与大多数字符上的衬线一样宽，这避免了一些电极用于多个位移中给定字符的衬线。
