    • A developing unit or similar recording unit which is removably mounted on an image recording apparatus is provided with a constant voltage device or similar level adjusting means which has a particular characteristic matching with recording color of the recording unit. The level adjusting means changes the level of a power supply (e.g. voltage) fed from a body of the apparatus to a level particular to the recording unit, i.e., to the color of toner stored therein. Identifying such a particular level, the apparatus body automatically sets up process conditions which are optimum for the identified level. Hence, the level detected by the apparatus body changes depending upon the kind of a recording unit actually mounted on the apparatus body, whereby optimum process conditions are set up.
    • 可拆卸地安装在图像记录装置上的显影单元或类似记录单元设置有具有与记录单元的记录颜色匹配的特定特性的恒压装置或类似电平调节装置。 电平调节装置将从设备本体供电的电源(例如电压)的电平改变为特定于记录单元的电平,即,调节器存储在其中的调色剂的颜色。 识别这样一个特定的水平,设备主体自动建立对于所识别的水平是最佳的过程条件。 因此,装置主体检测到的电平根据实际安装在装置主体上的记录装置的种类而改变,从而建立最佳的工艺条件。

    • An automatic density control device in a copying machine combined with an automatic document feeder capable of feeding a document onto a document support table has a document density detector for detecting the density of a document placed on the document support table, a scanner means movable in a forward direction for exposure to the image of the document on the document support table and movable in a backward direction for enabling the document density detector means to read the density of the document on the document support table, a reference position detector for detecting when the scanner means reaches a reference position, and a controller for determining the density of the document from a document density signal from the document density detector means in a range prior to generation of a signal by the reference position detector means when the scanner means moves back to the reference position, for determining an amount of exposure or an image developing bias voltage based on the document density signal, and for producing an output indicative of the amount of exposure or the image developing bias voltage in response to a first signal from the reference position detector means after the document has been fed by the automatic document feeder.

    • An endless belt is disposed closely above and parallel to a transparent platen. The belt is rotatably driven to move an original document for electrophotography or the like from an inlet onto the platen into engagement with a stopper. Pressure means cause the belt to initially press against the document with a large force to ensure document transport across the platen. The belt drive means is de-energized and the pressure force reduced just before the document engages the stopper to prevent jamming of the leading edge of the document against the stopper as the belt overtravels the document due to its inertia. After an imaging exposure of the document, the stopper is retracted and the belts driven to discharge the document from the platen into a tray provided at an outlet. Means are provided to discharge static electricity from the document and facilitate document stacking in the tray. A spacer plate limits upward and lateral movement of the belt, thereby preventing rebound and lateral displacement of the document when the document engages the stopper. The document feed means is designed to ensure that one document will be discharged completely before a subsequent document engages the stopper. The inertia of the belt and drive means is selected such that, even though a predetermined error range is unavoidable in the timing of de-energizing the drive means before the document engages the stopper, the drive means will be de-energized before the document engages the stopper and said inertia will be great enough to carry the document to the stopper.
    • 环形带紧密地设置在透明压板上方并平行。 带被可旋转地驱动以将用于电子照相术的原稿等从入口移动到压板上以与止动器接合。 压力意味着皮带首先用大的力压在文件上,以确保文件在压板上传送。 皮带驱动装置断电,并且在文件接合止动器之前压力减小,以防止当皮带由于其惯性而超过文件时,将文件的前缘卡在挡块上。 在文件的成像曝光之后,止动器被收回,并且带被驱动以将文档从压板排出到设置在出口处的托盘中。 提供装置用于从文件中释放静电并促进文件堆放在托盘中。 间隔板限制带的向上和向外运动,从而防止当文件接合塞子时文件的反弹和横向移位。 文件进给装置设计成确保在随后的文件接合塞子之前,一个文档将被完全排出。 选择皮带和驱动装置的惯性,使得即使在文件接合止动器之前在驱动装置断电的定时中不可避免地存在预定的误差范围,在文件接合之前驱动装置将被断电 止动器和所述惯性将足够大以将文件运送到止动器。

    • A bin for receiving sheets arranged in an apparatus for collating or sorting of sheets fed successively, which includes a rear end portion, a front end portion and an intermediate inclination portion connected therebetween. The front end portion includes a stopper or stoppers extending substantially vertical for stopping a front end of the sheet fed into the bin and a straight guide portion, on which the stopper or stoppers attached. The rear end portion includes an upright plate extending substantially vertical used for stopping and aligning a rear end of the sheet and a plate inclined so as to go down forwards in sheet feeding direction. The intermediate inclination portion is connected at front and rear end with the straight guide plate and the inclined plate of the rear end portion direct or through curve portion. In this bin the sheet can be aligned by using falling motion of the sheet with the own weight.
