    • A frame image (210) with 5-mm wide margins is formed on a paper sheet on the basis of the leading end and widthwise end positions of the paper sheet (107) detected by a contact image sensor (CIS) (204) in an adjustment mode. After that, this paper sheet (107) is circulated to a feed position via a circulating path (206) and paper convey path (205), and the CIS (204) detects the frame image position formed on the circulated paper sheet and its paper end portion so as to detect errors from the 5-mm wide margins. Correction values which can cancel these errors are stored in a correction parameter storage unit (71), and forming start timing control is made using these correction values upon forming an image in an actual job. In this way, an image forming apparatus which can detect the paper feed timing with high precision, can eliminate deterioration of the image position precision due to mounting errors and durability of components, and can always precisely adjust the image position is provided.
    • 基于由接触图像传感器(CIS)(204)检测到的纸张(107)的前端和宽度方向端位置,在纸张上形成具有5mm宽边缘的框架图像(210) 调整模式。 之后,该纸张(107)通过循环路径(206)和纸张输送路径(205)循环到进给位置,CIS(204)检测形成在循环纸张及其纸张上的框架图像位置 以便检测5毫米宽边距的误差。 能够抵消这些误差的校正值被存储在校正参数存储单元(71)中,并且在实际工作中形成图像时,使用这些校正值来形成开始定时控制。 以这种方式,能够以高精度检测送纸时刻的图像形成装置能够消除由于安装误差和部件的耐久性导致的图像位置精度的劣化,并且能够始终精确地调整图像位置。

    • With a memory access control portion without being intermediated by control of a CPU controlling an entire drive control of a motor, velocity data for setting velocity of a motor step by step are read out from a velocity table memory, and data value read out from the velocity table are converted by a time conversion circuit to time data, and based hereon a phase switching signal to operate the motor is generated in a phase signal generating portion. In addition, outputting of next data is requested to a memory access control portion in every time data output of a time conversion apparatus and occurrence of access to a next memory table is urged.

    • A document retrieval system retrieves a registered document from a document database responsive to a designated retrieval condition including one or a plurality of designated keywords. The document retrieval system includes a storage for storing keyword relationships which indicate relationship values of keywords and relations of the keywords and registered documents, an input part for designating a retrieval condition including one or plurality of designated keywords, where the retrieval condition determines a registered document which is to be retrieved from the storage, a selector for selecting a plurality of keyword relationships based on the retrieval condition and for converting the selected keyword relationships into analog signals, an analog operation circuit for calculating a relevance of document based on the analog signals, and a converter for converting the calculated relevance of document into a digital value.
    • 文档检索系统响应于包括一个或多个指定关键字的指定检索条件,从文档数据库检索注册文档。 文档检索系统包括用于存储关键字关系的存储器,该关键字关系指示关键字和关键词与注册文档的关系的关系值,用于指定包括一个或多个指定关键字的检索条件的输入部分,其中检索条件确定注册文档 将从所述存储器检索的选择器,用于基于所述检索条件选择多个关键字关系并将所选择的关键字关系转换为模拟信号的选择器,用于基于所述模拟信号计算文档的相关性的模拟运算电路, 以及用于将所计算的文档的相关性转换为数字值的转换器。
