    • A multilayer transformer component includes a chip body including a primary-side coil and a secondary-side coil, and first to fourth external electrodes. The primary-side coil includes a body portion, a first lead, and a second lead, and the secondary-side coil includes a body portion, a third lead, and a fourth lead. A first projection and a second projection of each body portion are arranged to lie substantially on a linear line. The first lead and the fourth lead are arranged to be line-symmetrical with respect to a center line which is arranged at an approximate center between respective distal ends of the first projection and the second projection, and which is perpendicular or substantially perpendicular to an overlying direction of the primary-side and secondary-side coils. The second lead and the third lead are also arranged to be line-symmetrical with respect to the center line.
    • 多层变压器部件包括具有初级侧线圈和次级侧线圈以及第一至第四外部电极的芯片体。 初级侧线圈包括主体部,第一引线和第二引线,次级侧线圈包括主体部,第三引线和第四引线。 每个主体部分的第一突起和第二突出部布置成基本上位于线性线上。 第一引线和第四引线被布置成相对于布置在第一突起和第二突起的相应远端之间的大致中心处的中心线线对称,并且垂直或基本上垂直于上覆 初级侧和次级侧线圈的方向。 第二引线和第三引线也被布置为相对于中心线线对称。

    • A coil component includes a first coil block and a second coil block that are sandwiched between magnetic substrates so as to form a chip body, and external electrodes that are attached to the chip body. The first coil block includes a coil body and an insulating body. The coil body includes an outer coil portion and an inner coil portion. The outer coil portion includes a first pattern group and a second pattern group, which are connected helically vertically in an alternating fashion. The inner coil portion includes a first spiral pattern and a second spiral pattern, which are connected to each other in series. In other words, low stray capacitance is achieved by the outer coil portion, while high inductance is achieved by the inner coil portion.
    • 线圈部件包括夹在磁性基板之间以形成芯片体的第一线圈块和第二线圈块,以及附接到芯片体的外部电极。 第一线圈块包括线圈体和绝缘体。 线圈体包括外部线圈部分和内部线圈部分。 外部线圈部分包括以交替方式螺旋地垂直连接的第一图案组和第二图案组。 内部线圈部分包括彼此串联连接的第一螺旋图案和第二螺旋图案。 换句话说,通过外部线圈部分实现低杂散电容,而通过内部线圈部分实现高电感。

    • A sheet conveying apparatus according to the invention includes a first conveying path; a sheet reverse conveying portion; a second conveying path; a third conveying path; and a movable guide portion configured to guide the conveyed sheet. The guide portion is moved to a position where the sheet can pass when the sheet is guided from the first conveying path to the second conveying path, and the guide portion is moved to a position where the guide portion guides the sheet to the third conveying path while blocking between the first and second conveying paths such that the sheet can not intrude from the second conveying path into the first conveying path when the sheet conveyed by the sheet reverse conveying portion is conveyed in the second direction.
    • 根据本发明的片材输送装置包括第一输送路径; 片材反向传送部分; 第二输送路径; 第三输送路径; 以及构造成引导所输送的纸张的可动引导部。 当片材从第一输送路径被引导到第二输送路径时,引导部分移动到片材可以通过的位置,并且引导部分移动到引导部分将片材引导到第三输送路径的位置 同时在第一和第二输送路径之间阻塞,使得当由纸张反向输送部分输送的纸张沿第二方向被输送时,纸张不能从第二输送路径侵入第一输送路径。
