摘要:
An image processing apparatus includes a process unit for reproducing an image on a document onto a recording medium and a detection circuit for detecting the status of the document image. A control circuit controls the process unit to reproduce the document image at a predetermined magnification. The status of the document may include the area of the image on the document, whether the document image is adjacent an edge of the document, the location of the edge of the document, or the disposition of the document. The magnification of reproduction of the document image is then controlled by the control circuit in accordance with the detection of that particular status. For example, if it is determined that the document image is adjacent the edge of the document, reproduction is controlled to be at reduced magnification. If the document is determined to be away from a reference position, a portion of the reproduced image may be erased so that only the actual document image is reproduced rather than unwanted background adjacent the document.
摘要:
An improved image forming apparatus for controlling image density at an optimum level. The image forming apparatus has a plurality of detectors for detecting an original image density. The detectors have mutually different detecting characteristics, wherein image forming conditions are controlled based on the outputs of the detectors. Control may be effected in accordance with a comparison of the detected values, and in accordance with a selected operation mode.

There is provided a moving body control device comprising a motor for driving a moving body, detector for detecting the speed of the motor, memory for storing a program for the phase comparison control of the speed of the motor, and control means for controlling the motor according to said program by inputting the output from the detector.
摘要:
There is an image forming apparatus in which images of a plurality of originals set on the original plate glass are individually exposed, scanned and read, and the read images are synthesized and recorded at arbitrary positions on a recording paper. This apparatus also has a device to record the images on the front and back surfaces of the recording paper. The synthetic recording and the front and back surface recording can be arbitrarily switched and selected. This apparatus is provided with a trimming function to erase unnecessary image portions of the images, a masking function to prevent the shaded portions from being recorded on an paper, and the image shift function to adjust the synthesizing positions of the images on the recording paper for every image. In the serial page copy mode adapted for book images, the masking function is automatically selected and the recording positions on the front and back surfaces of the recording paper are aligned to either one of the right and left sides of the paper, so that the binding margins can be secured on one selected side of the paper. The masking function is released when the serial page copy mode is released.
