摘要： A scanner starts to move for preliminary scanning and an exposure lamp of the scanner turns on after a prescribed period after the start of the movement of the scanner. When a rear edge of an original of the minimum size placed on a platen is irradiated by the scanning, an amount of irradiation of the exposure lamp attains a prescribed amount since the prescribed period has passed from the turn-on thereof. Accordingly, insufficiency of an irradiation amount of the exposure lamp does not occur at the time of original size detecting operation. Thus, detection operation is speeded up and the first copy speed of the image forming apparatus is improved.
摘要翻译：扫描仪开始移动以进行初步扫描，并且在扫描仪开始移动之后的规定时间段之后，扫描仪的曝光灯开启。当通过扫描照射放置在台板上的最小尺寸的原稿的后边缘时，从开启规定的时间段开始，曝光灯的照射量达到规定量。因此，在原尺寸检测操作时不会发生曝光灯的照射量不足。因此，检测操作加快，图像形成装置的第一复印速度提高。

摘要： When preliminary scanning is started, a reference signal is generated from a reference position sensor and a moving amount of the scanner is measured by counting. Change in intensity of the reflected light from a platen is detected by a first sensor according to movement of the scanner. When the detected intensity attains reference intensity, the moving amount of the scanner is stored. When the detected intensity attains again the reference intensity after it has been lower than the reference intensity, the stored moving amount of the scanner is updated. The time in which the detected intensity attains the reference intensity is measured and when it attains a predetermined time, absence of the original is determined and the scanner stops and returns. The size of the original is determined based on the moving amount of the scanner stored at that time.
摘要翻译：当初始扫描开始时，从参考位置传感器产生参考信号，并通过计数来测量扫描仪的移动量。根据扫描仪的移动，由第一传感器检测来自压板的反射光的强度变化。当检测到的强度达到参考强度时，存储扫描仪的移动量。当检测到的强度再次达到参考强度低于参考强度后，扫描器的存储的移动量被更新。测量检测强度达到参考强度的时间，并且当其达到预定时间时，确定不存在原稿并且扫描仪停止并返回。基于当时存储的扫描仪的移动量来确定原稿的尺寸。

摘要： A copying machine with plural developing units being capable of performing at least one edition mode and a simultaneous multi-mode in which the developing unit is switched from one to another on the way through one copying action is disclosed. In the simultaneous multi-mode, the position at which the developing unit is to be switched is designated by a position designation device such as keys provided on an operation panel and/or an editor, if connected to the copying machine. In this case, only one coordinate of the designated position in the sub-scan direction is employed to designate the switching position for the developing unit.

摘要： An improved paper feeding device, for example, for a copying machine is provided and is capable of warning a user of the status of available copy paper sheets. A movable support tray can be monitored to provide a measurement of the total initial height of the paper stack and subsequent movements of this paper stack to introduce individual copy paper sheets into a paper transport system can be correlated with the actual number of sheets that are transported. From these monitored values, it is possible to calculate the number of sheets remaining on the stack and to provide an audible, vocal or visual display of the actual number or relative condition to warn a user.
