    • A communication control method accomplishes minimum bandwidth guarantee and maximum bandwidth restriction and further allocates an extra-bandwidth in accordance with user's contact bandwidth. Fixed-length packets are once stored in corresponding partitions of a buffer in accordance with connection information contained in the packets and then transmits the packets from the storage sections in succession. Retrieval of a connection where the number of transmitted packets does not reach a lower-limit throughput and a packet to be transmitted exists in the corresponding partition is made with first priority, and retrieval is further made in order for a connection where the number of transmitted packets does not reach an intermediate throughput and a connection where the number of transmitted packets does not reach an upper-limit throughput. If the retrieval shows a hit connection, the packets are transmitted from the corresponding partition and one-time retrieval comes to an end.
    • 通信控制方法实现最小带宽保证和最大带宽限制,并根据用户的接触带宽进一步分配额外带宽。 固定长度的数据包根据数据包中包含的连接信息一次存储在缓冲器的相应分区中,然后连续发送存储部分的数据包。 在对应的分区中存在传送分组数目未达到下限吞吐量和分组的连接的检索以第一优先级进行,并进一步进行检索,以进行连接,其中发送的数量 分组没有达到中间吞吐量和传输分组数未达到上限吞吐量的连接。 如果检索显示命中连接,则从相应的分区发送分组,一次性检索结束。

    • This invention is directed to image reading capable of suppressing EMI unwanted radiation while maintaining image quality. To accomplish this, the following processing is executed when reading an original image by a photoelectric transducer. More specifically, a first driving signal where SSCG spread modulation is applied, and a second driving signal where no SSCG spread modulation is applied are generated from a reference signal. Either the first or second driving signal is selected, and a timing signal for reading the original image is generated based on the selected driving signal. The image signal obtained by the photoelectric transducer is latched using the timing signal. The latched image signal is transferred for subsequent image processing. Upon reading a one-line image original, the second driving signal is selected till the completion of the latch operation, and after the latch operation, the first driving signal is selected for an image signal transfer operation.
    • 本发明涉及能够在保持图像质量的同时抑制EMI不需要的辐射的图像读取。 为了实现这一点,当通过光电传感器读取原始图像时,执行以下处理。 更具体地,从参考信号产生施加SSCG扩展调制的第一驱动信号和不施加SSCG扩展调制的第二驱动信号。 选择第一或第二驱动信号,并且基于所选择的驱动信号产生用于读取原始图像的定时信号。 使用定时信号来锁存由光电变换器获得的图像信号。 被锁定的图像信号被传送用于随后的图像处理。 在读取单行图像原稿时,选择第二驱动信号直到锁存操作完成,并且在锁存操作之后,选择第一驱动信号进行图像信号传送操作。
