摘要： The image forming apparatus can retain a stable and high image quality for many hours without use of any high precise mechanical parts and without causing any non-uniformity and mal-registration in color image. In the image forming apparatus, an image recording medium (photosensitive drum) (6a) is driven by a rotative driving mechanism (pulleys and belts); and an image recording section (print bar) (6c) records an image repeatedly on the rotating image recording medium (6a) in a direction perpendicular to a rotational direction of the image recording medium. The image recorded on the image recording medium (6a) is transcribed onto an image transcribing medium (paper) (22) being fed in the rotational direction of the image recording medium (6a) to form an image. In particular, the apparatus comprises a rotation detecting section (rotary encoder) (6r) for detecting angular travel rates of the image recording medium (6a); and a recording timing control section (5) for controlling recording timing (HSYNC) at which the image is started to be recorded in the direction perpendicular to the rotational direction of the image recording medium (6a), on the basis of the angular travel rates detected by the rotation detecting section (6r).

摘要： The invention relates to a device for clamping film material in sheets to the recording drum of a reproduction arrangement and the method of operation of said device. The recording drum (1) has axially directed rows (6) of suction apertures for securing the image substrate (22) by a vacuum. In the walls (8) of the recording drum (1) there are suction channels (7), each interconnecting the suction apertures (5) of one row (6). In the recording drum (1) is arranged a vacuum distributor (25; 26; 27; 29) controllable by the rotary movement of the drum (1) which selectively connects the individual suction channels (7) or the appropriate rows (6) of suction apertures to a fixed vacuum pump (13). The vacuum distributor (25; 26; 27; 29) can be controlled in such a way that, during the clamping process, first of all the vacuum is applied to those rows of suction holes on which the leading region of the recording substrate (22) lies. This produces a high initial vacuum so that the recording substrate does not slip. Thereafter further rows (7) of suction apertures are connected in accordance with the greater extent to which the recording substrate is wound on the rotating recording drum (1) and vacuum is applied to them. The actuation of further rows (7) of suction apertures depending on the peripheral length of the recording substrate (22) is terminated at that row (7) on which the end region of the substrate (22) lies. The device especially makes it possible to clamp and secure large-size recording substrates on the recording drum (1) without creasing and slip.

摘要： An image reading method and apparatus are capable of high-quality reading of a transparent original with an optimum light quantity by maintaining both a transmitting light source unit for emitting light for reading the transparent original and a reading scanner of an image reader for receiving the transmitted light at an adequate relative position to keep their optical axes in alignment during scan reading. Such alignment is achieved by providing synchronization in scanning speed by placing either one of the transmitting light source unit and the reading scanner at an arbitrary selected position, scanning the proximity of the selected position with the other, determining a light quantity distribution, determining a synchronous position from the distribution, carrying out such synchronous position detection at two or more distinct positions, and calculating the scanning speed ratio of the transmitting light source unit to the reading scanner from the result. Alternatively, alignment is achieved by carrying out similar synchronous position detection, determining the relative spacing between the base points of said transmitting light source and said reading scanner from the distances from the respective base points to the synchronous position, and matching the scan start positions of the transmitting light source unit and the reading scanner in accordance with the relative spacing.

摘要： An image scanning and reading apparatus comprises a transparent drum (1) fro supporting a plurality of originals (2, 2′) and calibration reference portions (3, 3′) serving as references in reading the respective originals. A scanning head (5) is provided for scanning the rotating drum and an arithmetic unit (21) has a memory (20) for storing the positions of the calibration reference portions or the drum. The position of the calibration reference portions is stored prior to the reading of the originals and, when the scanning is started, the scanning head is moved to the stored position of a first calibration reference portion, the calibration is effected and the corresponding original is read taking the calibration data into account. The scanning of each successive original is similarly preceded by re-calibration using the corresponding reference portion, each calibration operation taking place while the drum is still rotating.

摘要： A novel closed loop direct position feedback control method and recording apparatus for producing on a recording medium a plurality of successive print lines or otherwise component images. An appendant demarcation device provide for the proper abutting and spacing of each independent print character to prevent or minimize any perceived "banding" in the printed image. The apparatus includes a device for transporting the medium along a path orthogonal to the print head, a recording station in the path and having a translating head for inking, pring, or otherwise suitable device, for producing single lines or swaths of print in conjunction with the indexed advance of the medium relative to the print head. The transport device is operative to advance a first print line or swath through the recording station to form a first print line, to identify and store the position coordinates of each print line or swath, and to advance the recording medium for successive line or swath printing. The direct position feedback control apparatus also includes demarcation sensing and printing device for relative positioning, whereby the distance between the location of any sensed or printed demarcation reference and the next successive print line is controlled such that each print line will neglect the positioning error in any previous print line or swath.

摘要： A recording apparatus of thermal transfer type includes a thermal head (5) having a plurality of linearly-arrayed heat generating elements selectively generating heat in response to the application of a character and pattern information signal providing the thermal transfer energy, and a carrier (1) having a coating of a thermally transferable recording material. A recording medium (7) recording character and pattern information is disposed between the carrier (1) and a platen roller (6) to be transported by the platen roller. At the time of recording character and pattern information on the recording medium (7), the thermal transfer energy is applied to the heat generating elements corresponding to the character and pattern information signal while pressing the thermal head against the platen roller. During the recording, the thermal transfer energy is controlled to correspond to the required density tone of the character and pattern information to be recorded.

摘要： A raster scanner includes a scanning module (12) which comprises a linear scanning array, a scanning slit permitting the array to view a document image one line at a time, and document transport for transporting documents past the scanning slit. To accommodate the disparity between scanning rates and user data rates, a relatively small buffer (14) stores lines of pixels output by the array pending demand by an output device (16). Intermittent operation of the scanner in response to buffer pixel demands is effected through starting and stopping of the document transport. A control (15, 45) is provided to prevent uneven spacing of scan lines resulting from scanning stopped documents or documents in the process of being accelerated or decelerated to and from scanning speed by the document transport.

摘要： An engraving system and method is disclosed having multiple engraving heads wherein the operation of each head is controllable so that a vertical screen and/or horizontal screen may be independently controlled, thereby facilitating enabling each engraving head to engrave in accordance with different screen rulings as may be selected by a user. The engraving system includes a signal generator for controlling the vertical screen by utilizing a plurality of vertical scalers which use a cylinder factor signal corresponding to the rotational position of a cylinder rotatably mounted on the engraver, as well as screen variables, such as a screen angle and a screen ruling, to generate independent vertical scaled or screen signals. These vertical scaled signals are used to independently energize the engraving heads to engrave patterns defining different vertical resolutions or vertical screens. This system and method also discloses a drive system for independently driving the engraving heads using the cylinder factor signal mentioned above and the screen variables which were input by the user to enable the engraving heads to engrave patterns having differing horizontal resolution or horizontal screens. Thus, the method and apparatus enable a user to simultaneously or independently change the vertical screen and horizontal screen and, consequently, the screen ruling for each pattern of engraved areas being engraved.
