摘要： An apparatus for detecting the density (concentration) of toner in a developer for an electrostatic recording apparatus includes an operatively moveable surface for carrying developer onto an electrostatic latent image bearing member during image development, a scraper element having at least a flat surface for scraping developer from the movable surface in a substantially steady and uniform stream along the flat face, and a substantially flat detection coil assembly having oppositely-directed faces. The coil assembly is mounted on, spaced apart from, and substantially parallel to the flat face of the scraper so that the stream of developer passes along both coil assembly faces directly after being scraped from the moveable surface, thereby enhancing the toner density detection sensitivity of the coil assembly.
摘要翻译：用于检测静电记录装置的显影剂中的调色剂的浓度（浓度）的装置包括：用于在图像显影期间将显影剂承载在静电潜像承载部件上的可操作地移动的表面，至少具有用于刮刮显影剂的平坦表面的刮刀元件从可动表面沿着平坦的表面以基本稳定和均匀的流体，以及具有相对方向的面的基本平坦的检测线圈组件。线圈组件安装在刮板的平坦表面上并基本上平行于刮板的平面，使得显影剂流在从可移动表面刮下之后直接沿着两个线圈组件表面通过，从而增强了调色剂浓度检测灵敏度线圈组件。

摘要： A copying apparatus having a power transmission means in which arranged between the plurality of driven means and the driving system is a power transmission control mechanism. Said power transmission control system is capable of reducing and absorbing the vibrations generated through the driving system and stably supplying the power to the plurality of driven means. Said power transmission control mechanism comprises a flange connected to said plurality of driven means, a flange connected to said driving system and an elastic member inserted beween said two flanges.
