Abstract: An image communication apparatus consists of a transmission section and reception section. The transmission section introduces the image of a text page, generates an image edit instruction for the image in response to the user's action, and transmits the image of the text page, with the image edit instruction being appended thereto, to other image communication apparatus. The reception section receives the image of a text page, with image edit instruction being appended thereto, sent from other image communication apparatus, edits the received image in accordance with the appended image edit instruction, and displays the edited image of the text page. The user of the sending unit merely needs to take a single instructing operation for displaying a text page and editing (rotating) the image to rectify the image layout direction if necessary.

The sensor pixel linear array consists of repeat patterns of color pixels linearly arrayed in a preset color order, the repeat patterns being symmetrical with respect to the midpoint of the sensor pixel linear array. The readout circuit reads out image signals line by line from the sensor pixel linear array. The output processing circuit distributes the readout signals into a plural number of color image signal routes, and outputs the readout signals of separated colors. The color linear image sensor thus constructed may be incorporated into an image processing system. The midpoint of the sensor pixel linear array is coincident with the optical axis of a lens of the optical system of the image processing system.

Abstract: An image forming apparatus includes an image carrying body on which a toner image is created. A sheet carrying/transporting rotational body adsorbs a recording sheet to which the toner image on the image carrying body is transferred, and transports the sheet. The recording sheet is detached after transfer from the sheet carrying/transporting rotating body, and an assisting device thrusts against the non-image area of the recording sheet to limit its detachment from the sheet carrying/transporting rotating body. The image forming device can prevent transportation failure and image smudging that is otherwise generated when a thick sheet provided with a curl before it is adsorbed to a sheet carrying/transporting rotational body is detached in the curved state from the rotational body and transported to a fusing means.

Abstract: An optical scanner including a semiconductor laser device, aperture, collimator, cylindrical lens, polygonal mirror and one f.theta. lens element molded from plastics. The first surface of the f.theta. lens in a deflecting plane (or the plane formed by the principal rays of light as deflected by the polygonal mirror) is aspheric whereas the second lens surface is toric. When taken in the deflecting plane, the first lens surface has a positive value of the near-axis radius of curvature and, hence, it is convex toward the polygonal mirror. Taken in a plane crossing the deflecting plane at right angles, the first lens surface forms an arc of a circle having a negative value of the radius of curvature and, hence, it is concave toward the polygonal mirror. When taken in the deflecting plane, the second lens surface forms an arc of a circle having a negative value of the radius of curvature and, hence, it is convex toward the scanning surface.

A mosaicing camera sequentially samples a series of small portions of a general scene, and a composite image of the entire general scene is transmitted. Simultaneously, an individual small area of the general scene where high time resolution is desirable is sampled at a high time resolution by a dedicated camera. The high-time-resolution images are then patched into the composite image.

Abstract: A customer-replaceable module having a fusing subsystem therein for a electrophotographic printer or copier includes three separate devices for detecting potentially dangerous temperature conditions within the module. A first thermal cutoff spaced from the fuser roll can detect high temperatures caused by incorrect software operation and hardware failures. A second thermal cutoff contacting the fuser roll outside of the paper path can detect failures associated with software malfunctions and paper shielding the first thermal cutoff. A thermistor contacting the fuser roll in the paper path can interface with the control software of the printer or copier itself. The thermal cutoffs function entirely independently of the control software of the printer or copier. The module may further include an electronically-readable memory for recording failure conditions.
