摘要： An image density reading apparatus in which an image of a document is irradiated by a light source and a density signal is generated from an image light reflected from the image. In the apparatus, there is an amplifier for amplifying a density signal on the basis of an amplifying gain and a signal processor for processing the amplified density signal in accordance with a predetermined processing algorithm to output a gain control signal. The amplifier is provided with a switch for changing a gain in response to the gain control signal.

摘要： The invention provides an image forming apparatus capable of performing an ordinary copy mode, whereby the entire surface of a document is scanned by an image reader to copy the entire surface on a copy sheet, and a serial page copy mode, whereby first and second half portions of the document are separately scanned to copy each half portion on a separate copy sheet. In the apparatus, copy sheets of different sizes are fed from a plurality of cassettes each storing a copy sheet of a predetermined size or a manual feed tray. There is provided a memory for memorizing a serial copy sheet size to be fed from the manual feed tray. When the serial page copy mode is selected in the manual feed mode, the image reader is controlled to separately scan the first and second half portions of the document on the basis of the serial copy sheet size.

摘要： A braking system for image forming apparatus returns an optical scan system in the image forming apparatus to a preselected home position after each scan of a document placed on a platen, within a predetermined period of time. Various factors including temperature, the number of copies of the document previously made, can change the operating performance of the braking system so that it does not return the optical scan system to the home position within the predetermined period. Detectors are provided to detect and sense the factors which will change the operating performance of the braking system. Brake control apparatus is responsive to the detectors and controls the braking system to return the optical scan system to its home position within the preselected period of time to thereby maintain the efficiency of the braking system even as the factors such as temperature, and number of copies previously made changes during operation of the image forming apparatus.

摘要： A copying apparatus includes a copy condition setting unit for setting copy conditions such as a copy count, a copy density, and a magnification. A standard mode setting unit initially sets the copy conditions upon starting of the apparatus to predetermined initial values, and a frequency calculating unit calculates a setting frequency of each copy condition set by the copy condition setting unit and the standard mode setting unit. When the frequency calculated by the frequency calculating unit exceeds a predetermined value, a correction unit corrects the corresponding copy condition to have the initial value set by the standard mode setting unit.
