Abstract: In an image recorder, a recording photobeam (25) and a reference photobeam (26) are periodically deflected by a polygon mirror (28) in the main scanning direction (X). The recording photobeam is supplied to a photosensitive film (600) while the reference beam is supplied to a transparent grating scale (31) on which a transparent area (T p ) and an opaque area (S d ) are formed. The combination boundary of the transparent area and the opaque area has a portion parallel to the main scanning direction. The reference beam transmitted through the transparent area is detected, and the photobeams are deflected in the subscanning direction (Y) by an acoustic-optical deflector (27) in response to the detected optical amount of the reference photobeam.

Abstract: A document camera is described for capturing an electronic image of a document, for subsequent optical character recognition. In order to avoid the need for a user to look through a viewfinder of the camera, the camera comprises a projector for projecting an optical field of view indicator on to the document. The user can see the projected indicator on the document page, indicating the effective field of view of the camera. The camera may include auto-focus and zooming mechanisms. In one form, the camera processes a detected image to determine a capture zone corresponding to whole regions of the document falling entirely within the field of view. The projected indicator is controlled to indicate only the capture zone. When the image is to be captured, the camera zooms in to the capture zone to capture the image at maximum resolution.

Abstract: There is provided a multiimage forming apparatus for forming image data onto photo sensitive drums by an electrophotographic system. This apparatus comprises: an image forming circuit to form different images onto the photo sensitive drums; a transfer device to transfer the images on the drums onto the same transfer paper; a conveying belt to convey the transfer paper; a control circuit to control the image forming circuit so as to form registration marks (34,35) to match the positions of the images onto the drums; CCD detectors (14,15) to detect the recording positions of the marks (34,35); and a correcting circuit to correct at least two of the positional direction in the conveying direction of the belt, the positional deviation in the direction perpendicular to the belt conveying direction, the magnification of the image, and the inclination of the image on the basis of the detection outputs of the detectors (14,15). With this apparatus, the positional deviations of the images which occur during the image formation can be accurately corrected, so that the images can be accurately formed on the transfer paper by reading and matching the position matching registration marks (34,35).

Abstract: A start of plot mark (111) consists of three portions, a first (111a), second (111b) and third (111c) portion each of equal area with the first and third portions being above a reference line (114) and spaced from each other by the second portion which is below the reference line. The first and second portions are used to generate a reference signal for use in measuring the zero crossing of the output signal from the start of plot mark thereby to automatically compensate for uncertainties in the zero crossing such as those uncertainties produced by differences in intensities of the start of plot coloration versus the background coloration of the print medium, differences in reflectivity and illumination of the print medium, and imbalances between sensor output signals.

Abstract: A printing device includes a first printer and a second printer which continuously print one or plural pieces of printing data onto a printing medium. In the printing device, the second printer includes a reading sensor, the first printer first prints the one or plural pieces of printing data onto the printing medium by forming a mark indicating a page of the printing medium or each of the plural pieces of the printing data, the reading sensor in the second printer subsequently reads the mark and matches printing surfaces of the printing medium to be printed by the first and second printers, and the second printer thereafter prints the printing data onto the printing medium. The printing device includes an information holding part which previously holds information on a relationship between the mark position and a size of the printing medium or a size of each of the plural pieces of printing data, and a mark position setting part which movably sets the mark position based on the information held in the information holding part in accordance with the size of the printing medium or the size of each of the plural pieces of printing data.
