Abstract: An electrophotographic apparatus capable of synthesizing two images with a cleaner boundary. Two images are synthesized by forming two images in respectively designated areas, and cleaner boundary is obtained by erasing any image in the boundary zone of these two images.

Abstract: An analog copying apparatus for optically exposing an original and copying it onto an arbitrary copy area on a copy paper has an area designating function and comprises: an image area designating apparatus to designate an arbitrary area on the original; a copy area designating apparatus to designate an arbitrary area on the copy paper; and copying means for copying the image in the image area into the copy area. This copying apparatus further has: an original moving apparatus to move the original on an original plate; a lens moving apparatus to move a lens provided in the optical path in an arbitrary direction; a cassette moving apparatus to move a cassette in which the copy papers are enclosed; and a resist control apparatus to control the resist timing, wherein the image in the image area is copied onto the copy area by means of at least one of or a combination of a plurality of these apparatuses.

Abstract: 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.

Abstract: An image forming apparatus comprises latent image forming means for forming a latent image on a photosensitive medium, reference latent image forming means for forming a reference latent image adjacent to the latent image, a plurality of light-emitting means disposed at intervals of a pitch D equal to or smaller than the width l of the reference latent image, and means for drivingly controlling the plurality of light-emitting means in accordance with the size of the latent image.

Abstract: 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.

Abstract: An image forming apparatus has a copying machine operable in a single side copy mode and a double side copy mode, a processor for commanding an interrupting copy operation in the double side copy mode, and a bin for storing, in a non-sort mode, the double-side copied papers fed from the copying machine in the interrupting copy operation.

Abstract: An image projector is adapted to change the magnification of a projected image by moving a zoom lens with its focal length being changed, wherein the zoom lens is moved to and then stopped at a goal position from the initial position in the first direction. When it is desired to move the zoom lens to another goal position in the second direction opposite to the first direction as viewed from the initial position, the zoom lens is once moved to its reversal position beyond the second goal position and thereafter moved from the reversal position to the second goal position.

Abstract: A device for controlling plural loads with phase locked loop control method by means of reference signals of different phases in order to avoid peak in electric power consumption.

Abstract: A copying apparatus comprises an optical lens, drive means for driving the optical lens, and control means for controlling the drive means. The control means changes over the output of the drive means in accordance with the distance of movement of the optical lens.
