    • An output circuit, for minimizing output idle current fluctuations and improve the output voltage range, has first and second transistors connected to first and second power sources, with a plurality of diodes connected to control terminals of the first and second transistors. The output circuit further includes a third transistor having a first terminal connected to the second power source and a second terminal connected to a predetermined position among the plurality of diodes. A predetermined voltage is applied from the diodes to the control terminal of the first transistor when the third transistor is saturated, to bring a level of an output of said output circuit close to a level of the second power source. A fourth transistor, a fifth transistor, a first resistor, and a capacitor are also provided. The forth transistor has a control terminal connected to an output of a differential circuit, and a first terminal connected to the second power source through the first resistor as well as to the control terminals of the third and fifth transistors. A second terminal is connected to the first power source, with the fifth transistor having a first terminal connected to the second power source and a second terminal connected to the control terminal of the second transistor. The capacitor is connected between the control terminal of the fourth transistor and the second terminal of the fifth transistor. This output circuit also limits the output voltage without changing the impedance of the high-impedance input.

    • The invention relates to an optical element being conveniently useful, for example as an external cover of transmitter and/or receiver for optical communication and more particularly to a surface-curved optical element comprising a transparent body of a refractive index n having a pair of boundary surfaces defined in their cross-section by the corresponding pair of ellipsoidal curves of an eccentricity 1/n. The boundary surfaces of this surface-curved optical element are configured so that they should have their focal points aligned with one another on a straight line and their focal points which are remote from vertices of the respective ellipsoidal surfaces corresponding to the apsides of the respective ellipsoidal curves should be coincident with each other, whereby parallel light rays entering the surface-curved optical element should emerge from this in the form of the parallel light rays without any disturbance.

    • An image forming apparatus in accordance with the present invention is provided with a unit composed of members such as a photoreceptor drum and an optical system, the unit being attachably and detachably provided with respect to the image forming apparatus main body. With the arrangement, the replacement of the photoreceptor drum can be made at the user's end with ease. It is not necessary to carry out fine adjustments at the user's end for positioning the photoreceptor drum and optical system with respect to the image forming apparatus main body. Thus, professional skill is not required for the replacement of the photoreceptor drum, thereby resulting in that the operations such as maintenance can be effectively made. It is preferable that a cleaner is further provided for removing any contaminated materials adhering to the inner surface of the photoreceptor drum. With the cleaner, the contaminated materials can be removed from the inner surface of the photoreceptor drum, thereby avoiding that the exposure of the photoreceptor drum is not appropriately carried out.
    • 根据本发明的图像形成装置设置有由诸如感光鼓和光学系统的部件组成的单元,该单元可相对于图像形成装置主体可拆卸地设置。 通过这种布置,可以容易地在用户端进行感光鼓的更换。 在用户端不需要进行微调,以便相对于图像形成装置主体定位感光鼓和光学系统。 因此,为了更换感光鼓不需要专业技术,从而可以有效地进行诸如维护的操作。 优选的是,进一步设置用于除去粘附在感光鼓的内表面上的任何污染物质的清洁器。 利用清洁器,可以从感光鼓的内表面去除受污染的材料,从而避免感光鼓的曝光不适当地进行。

    • The present invention provides in a preferred embodiment a developer container having a supply and discharge shaft which is driven and rotated in a direction by a supply and discharge shaft motor, a supply screw mounted on one of the ends of the supply and discharge shaft for bringing unused developer in a developer supply container into a developer container, and a discharge screw mounted on the other end of the supply and discharge shaft for discharging the developer in the developer container through a developer discharge opening. With this structure, the ratio of replacing old developer with new developer in the developer container is controlled in the desired manner, and the charging property of the developer is maintained substantially uniform. Additionally, since the replacement efficiency of the developer is improved, the consumption of the developer is reduced. Moreover, even when a copying machine is tilted, a large amount of developer is unlikely to be discharged.
    • 本发明在优选实施例中提供了一种显影剂容器,该容器具有一供给排出轴,该排放轴由一供给排出轴电动机驱动并沿一方向旋转;供给螺钉,其安装在供排排轴的一端上, 显影剂供应容器中的未使用的显影剂进入显影剂容器,以及安装在供排排轴的另一端的排出螺杆,用于通过显影剂排出口排出显影剂容器中的显影剂。 利用这种结构,以期望的方式控制在显影剂容器中更换旧显影剂与新显影剂的比例,并且显影剂的带电性能保持基本均匀。 此外,由于显影剂的替换效率提高,因此显影剂的消耗降低。 此外,即使当复印机倾斜时,大量的显影剂也不太可能被排出。
