    Abstract: This invention provides a control device for a vibration wave motor. In case the device executes an operation involving a large variation in the load while the motor is controlled at a target speed by the driving frequency with a feedback system, such feedback control is inhibited or the response of the feedback control is restricted in order to avoid the drawback resulting from the feedback control at the generation of the variation in the load.

    Abstract: To properly cut light except for visible light and improve read precision, there is provided an image reading apparatus having a plurality of photoelectric conversion elements (210-1,2,3,4). The image reading apparatus includes an image information detecting unit in which the photoelectric conversion elements are arranged on a single chip (210-14), a first light-shielding unit (210-8,9,10), arranged near the photoelectric conversion elements, for transmitting specific visible light, and a second light-shielding unit (210-5,11), arranged near the photoelectric conversion elements at a position different from that of the first light-shielding unit, for partially shielding light except for the visible light.

    Abstract: An indicator is provided for any arbitrary signal information, related to image processing. A keyboard is associated with the indicator, and a memory stores required information signals. A control device operates the indication of image transmission for information to the indicator. A second indicator may be provided for further information signals as required in addition to signals displayed by the first indicator. Further image processing inputs may be provided, while a memory stores such input signals. The signals in the memory may be changed by a special device. The system enhances user operation and is suitable for facsimile equipment, photocopiers and word processors.

    Abstract: An image processing system has a line sensor for reading an image, a binarizing circuit for binarizing the read image data, a clock generator for generating a clock for transferring the image data, and a frequency changing circuit for changing the frequency of the clock from the clock generator using a decimal counter (e.g., a DRM) to allow image reproduction of any desired magnification factor without errors.
