摘要:
An image reproducing apparatus with or without an ADF has an optical system for scanning an original, a developing unit, a fixing unit, a differential amplifier, and a microcomputer. Original image density can be measured properly in any mode of the apparatus. The image is reproduced to have optimal density by a lamp control voltage from the differential amplifier. Toner deficiency or the like can be indicated with a few number or displays and/or indicators. Upon detection of toner deficiency or the like, the current copying cycle is completed first and the apparatus is stopped. The copying operation can be resumed after the toner deficiency or the like is eliminated.

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. A copy magnification may be calculated and set from the image area and copy area, and the image in the image area is copied onto the copy area on the basis of this magnification.

A copying apparatus for optically reading images on the same or different originals and copying them into an arbitrary copy area on a copy paper has an area designating function and includes an image area designating apparatus to designate an arbitrary area on the original; a multiple transfer apparatus to multiple transfer the images in a plurality of image areas designated by the image area designating apparatus; a copy area designating apparatus to designate an arbitrary area on the copy paper and to copy the images in the image areas into the copy area designated; and a color designating apparatus to respectively designate the colors for a plurality of image areas designated by the image area designating apparatus. The images in the image areas are multiple transferred into the copy area by the multiple transfer apparatus on the basis of the designated colors.

摘要:
There is a multi-color copying apparatus having image processing functions which can easily designate arbitrary areas when the trimming or masking is executed. This apparatus comprises: an area designating device to designate the first area of the original; a first developing device to develop the image of the first area in the first color; a second developing device to develop the image of the second area in the second color; and a control circuit for making the first developing device operative without making the second developing device operative in accordance with the designation of the first area and, after completion of the development of the image of the first area, making the second developing device operative without making the first developing device operative. The control circuit inhibits the operation of the first or second developing device by moving the first or second developing device to a position away from the photo sensitive drum, or by applying the bias voltage to the first or second developing device such that the toner from the inoperative developing device is not deposited onto the drum.
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 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.
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.
