摘要:
There is disclosed a color copier or the line in which an original image is separated into plural image signals of different color components, which are repeatedly subjected to a determined signal process to reproduce the original image with an improved image quality and with a simple structure.
摘要:
A recording apparatus with plural recording units, such as an ink jet printer with plural ink jet recording heads, in which the number of flexible cables and the number of signal lines for driving the plural recording units are reduced by the common use of said signal lines for plural recording units.
摘要:
An image formation apparatus includes an electrostatically chargeable member having an optical density that changes with change of its reproducing power. A charging device forms an electrostatic latent image on the chargeable member, and a developing device develops the electrostatic latent image into a visual image. A transfer mechanism then transfers the visual image onto a recording member. A detector detects the optical density before the chargeable member is charged by the charging device and a control device controls at least one of the charging device, the developing device, and the transfer mechanism in accordance with the output of the detector.
摘要:
There is disclosed an image processing apparatus for processing an image signal in which the mode of image processing is rendered variable to adapt to plural input devices. More specifically, a conversion matrix circuit receives image signals from one of a plurality of different input devices and converts the image signals into corrected additive primary color signals red, green and blue. The conversion matrix circuit compensates for any differences in the spectral characteristics of the different input devices. The matrix includes a plurality of conversion tables stored in memory for performing the conversion. A selected one of the conversion tables is addressed by the image signals.
摘要:
A lens assembly including an adjusting mechanism arranged to render a part or parts of or all of the optical elements, constituting an optical system, movable by an electric motor drive arrangement, the lens barrel is composed of a stator or stators of one or a plurality of linear motors for driving the adjusting mechanism. The movable element of the linear motor corresponding with the stator is formed into a hollow space, in which each of the movable optical elements can be accommodated.
摘要:
A halftone image recording apparatus has a photoelectric converter for generating a density signal representing the density level of an image, a periodical or random signal generator for periodically or randomly generating level signals, an adder for adding the density signal and the level signals, a memory for storing the addition signal from the adder, a pattern generator for generating an image pattern, and an ink jet head or the like to record the image pattern. Pseudooutlines are eliminated without requiring an increase in the reading resolution and without imparing the resolution during recording. Input image data is compressed and a memory of smaller capacity can be used.

摘要:
Apparatus for fixing a toner image on a support by pressing and heating it. To heat the toner image, the apparatus comprises first heating means for heating it with transmission or convection heat and second heating means for heating the same with radiation heat. A detecting means detects the temperature of the first heating means and in accordance with the detected information the second heating means is controlled so as to maintain the thermal condition for fixing in a constant and stable state with improved thermal efficiency.
摘要:
The disclosure describes an improved electrostatic printing in which cleaning step and developing step are united together as single combined step. It is possible to carry out charging step and transferring step with same single means. The electrostatic printing is adaptable for making a large number of prints at a high speed. The developing agent can be recovered and reused very efficiently.
摘要:
The exhaust of stocked copying paper and the failure in feeding copying paper are detected so that means for driving a feeding system may be immediately stopped, and no failure in feeding copying paper is detected and failure in discharging copying paper is detected so that every operation in the photocopying machine may be stopped and also the power supply to the photocopying machine may be interrupted. The highly efficient and safeguarded operation of the photocopying machine may be ensured.
