摘要： A dust tolerant scanner without a transparent plate to support objects scanned by its media scan assembly. Other dust or debris collecting surfaces in the optical path of the scanner are positioned as far away as possible from an object focal plane of the media scan assembly. The media scan assembly includes upper and lower document feeder portions which define a media path adjacent to a reference surface of the upper portion. The lower document feeder portion includes a media conformance member which positions pieces of media against the reference surface as the pieces of media are advanced along the media path. The media conformance member includes ramp portions and an aperture which provides an optical path between the object focal plane and a sensor focal plane within the scanner.

摘要： An inkjet printer (10) has a movable carriage (12) supported above an ink-receiving medium by a rail (14) defining a carriage axis. A cartridge holder (16) is mounted on the carriage and having at least one cartridge compartment (18), each of the at least one compartment having a compliant compartment wall (82). Each compartment is providing with an opening at one end (19) of the carriage floor for receiving the snout (72) of an ink jet printer cartridge (20) on which is mounted a nozzle plate with more that one nozzle for depositing ink onto the ink-receiving medium. Each compartment is also provided with equalizing structure for maintaining the cartridge substantially perpendicular to the carriage axis when the compliant compartment wall is deflected by a spring at the middle of the compartment forcing two datum surfaces on the cartridge against front and rear supporting surfaces on the compartment wall. The equalizing structure preferably includes a second opening (21) at the other end of the floor.

摘要： An automatic document feeder mounted removably to a computer input device having a medium receiving and supporting surface includes a plurality of interconnectable modular assemblies for defining a medium path that extends from a medium input tray to a medium output tray via the medium receiving and supporting surface of the computer input device. One of the modular assemblies is a main chassis assembly includes an integrally formed main chassis shell having a substantially planar base. The input tray has a document receiving surface with a concave shape in both the vertical and horizontal planes to help facilitate proper sheet stiffening and alignment for sheet loading purposes onto the receiving and supporting surface of the computer input device. A pair of spaced apart drive rollers mounted to a spring loaded drive axle engage in seriatim individual sheets for loading and unloading them onto the supporting surface of the computer input device. A motor driven transmission system is mounted to a central portion of the drive axle to balance the drive force applied by the drive rollers so that the individual medium sheets are loaded and unloaded without any substantial sheet skewing.

摘要： A media detection system includes a sensor and a flag. The flag is pivotally supported proximate to a media path through which media is moved. The flag pivots as media is moved through the media path such that the flag interacts with the sensor to cause the sensor to alternate between two states and to produce at least four signals representing positioning of the media along the path. The flag is configured to remain substantially in one angular position for a portion of time while the medium is moving and in contact with the flag.

8.发明授权Thin, shallow-angle serrated hold-down with improved warming, for better ink control in a liquid-ink printer 失效薄而浅的锯齿状锯齿形，具有改善的温度，可在液体墨水打印机中实现更好的墨水控制

摘要： The invention minimizes liquid-ink deposition on the top and edge of a guide-plate (or "hold-down" plate), and also minimizes running of deposited liquid ink along the top to the edge. Through these two effects together the rate of ink deposition on the top and edge of the plate is held below the volume of ink per unit time that can dry there. The invention also minimizes ink transfer from the edge onto the print medium. The deposition-minimizing provisions include two features: serration, and a very fine vertical dimension of the edge itself. These features enhance air flow, and thus transport of ink spray, rapidly across the edge--discouraging formation of a dead-air zone from which spray readily precipitates onto the edge. The thin edge also presents a smaller direct target for ink droplets. The serrations may enhance transport by (1) promoting a more-favorable balance between laminar and turbulent flow; or (2) enabling air passage between opposed surfaces of the plate--from underside to top surface--creating an updraft to lift the flow away from the edge; or (3) both. To minimize running of liquid ink along the plate, the plate is mounted essentially all exposed to heat from a heater whose main purpose is drying ink on the print medium: this raises the plate temperature and so promotes drying of ink on the plate too. To further minimize running of liquid ink along the plate toward the edge, the edge panel is at a very shallow angle; and the air-flow provisions mentioned above also help carry away liquid carrier, from whatever ink does fall onto the edge, thus accelerating drying. To minimize brushing off even a slight accumulation of ink (liquid or dry) onto the medium, the serrations also raise most of the edge away from the medium.
摘要翻译： 本发明使引导板（或“压紧”板）的顶部和边缘上的液体 - 油墨沉积最小化，并且还使沿着顶部到边缘的沉积的液体墨的运行最小化。 通过这两种效应，板上的油墨沉积速率保持在每单位时间内可以干燥的油墨体积以下。 本发明还最小化从边缘到打印介质的墨传递。 沉积最小化规定包括两个特征：锯齿和边缘本身的非常细小的垂直尺寸。 这些特征增强了空气流动，并且因此快速地传送喷墨，从而使喷雾容易地从其中沉淀到边缘上的死空气区域的边缘阻止形成。 薄边缘还呈现较小的墨滴直接目标。 锯齿可以通过（1）促进层流和湍流之间更有利的平衡来增强运输; 或（2）使得板的相对表面之间的空气通过 - 从下侧到顶部表面 - 产生上升气流以将流体提升离开边缘; 或（3）两者。 为了最小化液体墨沿着板的运行，板主要安装在来自加热器的所有热量上，加热器的主要目的是在印刷介质上干燥墨水：这提高了印版温度，从而促进了印版上墨水的干燥。 为了进一步最小化液体墨沿着板朝向边缘的运行，边缘面板处于非常浅的角度; 上述的气流装置也有助于携带液体载体，从任何油墨落在边缘上，从而加速干燥。 为了尽可能减少即使油墨（液体或干燥）在介质上的轻微积聚，锯齿也将大部分边缘从介质中提升出来。
