    • A removable device is removably attachable to an image forming apparatus main body. The removable device includes an information storage device, a holder, and a low frictional structure. The information storage device includes: an information storage unit that stores information to be communicated between the apparatus main body and the removable device; a terminal to be contacted with an apparatus main-body terminal, for communicating information with the apparatus main body; and a substrate that holds the information storage unit and the terminal and that includes a guide to be fitted to a protrusion provided on the apparatus main body. The holder holds the substrate such that the substrate can move, when the removable device approaches the apparatus main-body terminal, on a virtual plane intersecting with a moving direction of the removable device. The low frictional structure is arranged on a contact area between the substrate and the holder.
    • 可去除装置可移除地附接到图像形成装置主体。 可移除装置包括信息存储装置,保持器和低摩擦结构。 信息存储装置包括:信息存储单元,其存储要在装置主体和可移除装置之间通信的信息; 与设备主体终端接触的终端,用于与设备主体通信信息; 以及基板,其保持信息存储单元和端子,并且包括将被配合到设置在设备主体上的突起的引导件。 保持器保持基板,使得当可拆卸装置接近装置主体端子时,基板可以在与可移除装置的移动方向相交的虚拟平面上移动。 低摩擦结构布置在基板和支架之间的接触区域上。

    • Disclosed is a technology that specifies each of a plurality of two-dimensional codes in an image and reduces the processing time for judging color in each cell region in each specified two-dimensional code. Based on edge images generated from obtained images, candidate regions among these edge images are extracted, a judgment is made about whether or not a characteristic pattern is included in each of the corresponding regions in the original images that correspond to these extracted candidate regions, and then the two-dimensional code regions are detected from among the original images. The color is judged both for each pixel group that comprises each row of that region and for each pixel cell, in pixel array order. If it is determined that a certain number or more pixels in each row that corresponds to each cell region are included in the color judgment region, color judgment is omitted for the remaining pixels in that row.
    • 公开了一种指定图像中的多个二维码中的每一个的技术,并且减少了用于在每个指定的二维码中对每个小区区域中的颜色进行判断的处理时间。 基于从所获得的图像生成的边缘图像,提取这些边缘图像中的候选区域,判断在与这些提取的候选区域相对应的原始图像中的每个相应区域中是否包括特征图案,以及 然后从原始图像中检测二维码区域。 对于包括该区域的每行和每个像素单元的每个像素组,以像素阵列顺序判断颜色。 如果确定在颜色判断区域中包括与每个单元区域相对应的每行中的某一个或多个像素,则对于该行中的剩余像素,不再进行颜色判断。
