摘要： A printer accurately controls the passage of print media therethrough and maintains the print media taut as the print media passes through a printing zone while the media is printed by an ink jet printer. The print media sheet is preferably carried by a rotating drum in a first direction through the printing zone, with the drum being reversed to cause the exiting of the print media sheet from the printer. A pressure fixing or fusing apparatus may be positioned to flatten ink spots on the print media as the print media exits from the printer. The pressure fixing or fusing mechanism is preferably used in the case of a hot-melt or phase-change ink jet printer.
摘要翻译：当打印介质由喷墨打印机打印时，打印机准确地控制打印介质通过其中并且随着打印介质通过打印区域而使打印介质紧张。打印介质片材优选地通过旋转滚筒沿第一方向通过打印区域携带，其中滚筒被反转以使打印介质片材从打印机中排出。当打印介质从打印机出来时，压力定影或定影装置可以被定位成使打印介质上的墨斑变平。在热熔或相变喷墨打印机的情况下，优选使用压力定影或定影机构。

摘要： A print medium sheet feeding system for an ink jet printer having a print head with a planar array of jets is provided by clamping the leading edge of a paper after it is passed through a printing zone to a rotating assembly of parallel disks. The sheet is pulled through the printing zone by rotating the disk with the clamp being carried with the rotating drum. A platen may be provided which has a flat surface in the printing zone forming a tangent to the outer surface of the rotating disks. Alternatively, the platen may be removed and the sheet held in tension between the clamp and a nip region formed by a spring plate held against a restraining plate. In an alternative embodiment, the sheet is initially clamped against the drum by the combination of a lever arm which is selectively engagable with the drum for rotation therewith and an attached actuating arm having a plate which secures a sheet to the drum surface. The resulting clamp rotates with the drum until the sheet passes below idler rollers which are biased against the drum surface. These rollers then hold the sheet against the drum for motion of the sheet with the drum surface. The actuating arm is released from the drum after a sheet passes below the rollers, thereby allowing any sized sheet to be fed through the system.
摘要翻译：具有喷射平面阵列的打印头的喷墨打印机的打印介质输纸系统通过在纸张通过打印区域之后将纸张的前缘夹紧到平行盘的旋转组件来提供。通过旋转磁盘将片材拉过打印区域，夹具与转鼓一起运送。可以设置在打印区域中具有平坦表面的压板，其形成与旋转盘的外表面相切。或者，可以移除压板并且片材保持在夹具与由弹簧板形成的夹持区域之间的张力保持在限制板上。在替代实施例中，片材首先通过可选择性地与滚筒接合以便与其一起旋转的杠杆臂的组合和附接的致动臂组合地抵靠着滚筒，该致动臂具有将片材固定到滚筒表面的板。所得到的夹具与滚筒一起旋转，直到片材通过偏压在滚筒表面下方的惰轮。然后，这些辊将片材保持在鼓上以使片材与鼓表面一起运动。在纸张通过辊子之后，致动臂从滚筒中释放，从而允许任何尺寸的纸张通过系统进给。

摘要： The present invention entails an accurate, sensitive, and stable means of mounting a print head to a movable carriage assembly of the type used in computer output printers. The invention uses one pair of planar mounting surfaces and one pair of angled mounting surfaces between the print head and the carriage of a print head assembly. A pair of pivoting clamping plates apply a force that urges both pairs of mounting surfaces together while simultaneously providing adjustment of the translation of the print head relative to the carriage. The translation across the oppositely angled surfaces on two of the four mounting surfaces provides an accurate azimuthal angle adjustment for the print head. Because the other mounting surfaces are in the same plane, the translation affects only the azimuthal angle.
摘要翻译：本发明需要将打印头安装到用于计算机输出打印机中的类型的可移动托架组件的准确，灵敏和稳定的装置。本发明在打印头和打印头组件的托架之间使用一对平面安装表面和一对成角度的安装表面。一对枢转夹紧板施加将两对安装表面一起推动的力，同时提供打印头相对于托架的平移的调整。在四个安装表面中的两个上的相对倾斜的表面上的平移提供了用于打印头的精确的方位角调整。因为其他安装表面在同一平面上，平移仅影响方位角。

摘要： In accordance with the present invention, a drum (10) has a central shaft (11) which is rotatably mounted to a drum supporting frame (12). A mount (26) pivotally connects one side (30) of the frame (12) to a cabinet (14) for pivoting about a frame pivot (73). A mount (15) rigidly secures the other frame side (32) to the base (14). An isolation mounting bracket (86) supports an optical encoder (84) in position to monitor the velocity of the shaft (11). Bracket (86) has pivots (98, 100) which cooperate with the frame pivot (73) to provide in effect a parallelogram support structure for the optical encoder (84). Thus, the encoder (84) may translate, but not rotate, in response to vibrations of the frame (12) so as to minimize or eliminate erroneous encoder velocity readings otherwise arising from such vibrations.
摘要翻译：根据本发明，滚筒（10）具有可旋转地安装在滚筒支撑框架（12）上的中心轴（11）。安装件（26）将框架（12）的一侧（30）枢转地连接到用于围绕框架枢轴（73）枢转的机壳（14）。安装座（15）将另一框架侧（32）刚性固定到基座（14）上。隔离安装支架（86）支撑位置上的光学编码器（84）以监测轴（11）的速度。支架（86）具有与框架枢轴（73）配合的枢轴（98,100），以实际提供光学编码器（84）的平行四边形支撑结构。因此，编码器（84）可以响应于框架（12）的振动而平移但不旋转，以便最小化或消除否则由这种振动引起的错误的编码器速度读数。
