    • In a personal data assistant, a main body includes an input sheet, which is turnable between a first position where at least a part of a display unit of the personal data assistant is covered and a second position where the display unit is not covered. The input sheet has various types of keys formed thereon. When any one of the keys is pressed on the input sheet, a pressure is applied to an input device formed on the display unit, and an input coordinate is detected by the change of, for example, the resistance value of the input device. Since the surface of the display unit is not entirely covered with the input sheet, the display in the range of the display unit which is not covered with the input sheet is not made dark. Further, since the input device is not directly touched with a finger, the input device is prevented from being made dirty, and the display of the display unit under the input device is prevented from being difficult to be seen. Accordingly, the operability of the personal data assistant can be improved while displaying information clearly.
    • 在个人数据助理中,主体包括输入片,该输入片可以在个人数据助理的显示单元的至少一部分被覆盖的第一位置与不覆盖显示单元的第二位置之间转动。 输入表具有形成在其上的各种键。 当在输入页面上按压任何一个键时,对形成在显示单元上的输入装置施加压力,并且通过例如输入装置的电阻值的改变来检测输入坐标。 由于显示单元的表面不完全被输入纸覆盖,所以未被输入纸张覆盖的显示单元的范围内的显示不会变暗。 此外,由于输入装置不是用手指直接触摸,因此防止输入装置变脏,并且防止显示单元在输入装置下的显示难以被看到。 因此,可以在显示信息的同时改善个人数据助理的可操作性。

    • An image input device identifies what part of the optical input system needs cleaning when there is dust or other foreign matter in the optical input system. This image input device has an image noise position detector for capturing image data from a scanner, and detecting the main scanning address of noise information corresponding to image noise present in the image data; a focus calculator for calculating focus information around the main scanning address detected by the image noise position detector; focus information storage for storing focus information for each subscanning line; and a foreign matter position determining circuit for determining the location of foreign matter on the scanner based on the focus information stored in the focus information storage.
    • 图像输入装置识别在光输入系统中存在灰尘或其它异物时,什么部分的光输入系统需要清洁。 该图像输入装置具有用于从扫描仪捕获图像数据的图像噪声位置检测器,并且检测与图像数据中存在的图像噪声相对应的噪声信息的主扫描地址; 焦点计算器,用于计算由图像噪声位置检测器检测的主扫描地址周围的聚焦信息; 用于存储每个副扫描线的焦点信息的焦点信息存储; 以及异物位置确定电路,用于基于存储在焦点信息存储器中的焦点信息确定扫描仪上的异物的位置。
