    • A modular type image forming system includes a laser printer main unit and a plurality of optional units, such as both side processing unit, a large quantity paper feeding unit and a mail box unit, each of which is operatively coupled to said main unit through a commonly usable optical fiber cable through a commonly usable connector. Each unit has its own CPU and serial communications between the CPUs of different units may be carried out through the optical cables. The CPU of the main unit may determine the identity of each of the optional units connected thereto through such communications. The main unit also includes an interface circuit through which the main unit is operatively coupled to each of the optional units. The interface circuit includes a port selector which establishes a connection pattern between the main and optional units in accordance with the identity information of each of the optional units connected. When paper is fed into a transportation path, paper ID is assigned to the paper and retained until the paper is discharged. If the paper is removed from the path without passing a predetermined location, the same image is printed again.
    • 模块化图像形成系统包括激光打印机主单元和多个可选单元,诸如两侧处理单元,大量给纸单元和邮箱单元,每个可选单元通过一个或多个单元可操作地耦合到所述主单元 通常可用的光缆通过通用的连接器。 每个单元都有自己的CPU,不同单元的CPU之间的串行通信可以通过光缆进行。 主单元的CPU可以通过这种通信来确定与其连接的每个可选单元的身份。 主单元还包括接口电路,主单元通过该接口电路可操作地耦合到每个可选单元。 接口电路包括端口选择器,其根据所连接的每个可选单元的身份信息建立主单元和可选单元之间的连接模式。 将纸张送入运输路径时,将纸张ID分配给纸张,并保留到纸张排出。 如果在不通过预定位置的情况下将纸张从路径中取出,则再次打印相同的图像。

    • It is to provide a radio communication system capable of performing highly reliable reading/writing communication even though the RFID tags face in the random directions. The radio communication system comprises an RFID tag used for identification, a reader/writer for performing transmission and reception of information between the RFID tag by radio waves, and a plurality of reflecting plates in a space where a plurality of RFID tags are accumulated. The reflecting plates direct traveling direction of the radio wave irradiated from the reader/writer towards the RFID tags. A part of the radio waves irradiated from an antenna of the reader/writer is directed to travel three-dimensionally towards the space by the effect of the reflecting plates. Moreover, the radio waves traveling in the same direction among the reflected radio waves by the plurality of reflecting plates together allow attenuation caused due to distance to be reduced extremely.
    • 即使RFID标签面向随机方向,也能够提供能够进行高可靠性的读/写通信的无线通信系统。 无线电通信系统包括用于识别的RFID标签,用于通过无线电波在RFID标签之间执行信息发送和接收的读取器/写入器以及在多个RFID标签被积聚的空间中的多个反射板。 反射板将从读取器/写入器辐射的无线电波的行进方向直接朝向RFID标签。 从读取器/写入器的天线照射的无线电波的一部分被反射板的作用三维地朝向该空间行进。 此外,通过多个反射板在反射的无线电波中以相同的方向行进的无线电波一起允许由于距离引起的衰减被极大地降低。
