Abstract:
An image reading apparatus is provided with an optical reading device for scanning a stationary original placed on a platen to read image on the original; a drive device for moving the optical reading device at the first moving speed and the second or slow moving speed; a detection device for determining a type of image data read by the optical reading device as either the first type, i.e. monotone data, or the second type, i.e. color data; and a scan control device for obtaining and storing image data while scanning a document at the first moving speed. A switching control device switches the drive device to the second moving speed when the detecting device determines the image data read at the first moving speed to be the second type.
Abstract:
The flat bed raster drawing machine is controlled automatically, includes a flat table to bear a flexible material, such as paper, fixed guides on which a carriage moves perpendicular to the lengthwise axis of the flexible material between the aforementioned guides, and a second carriage bearing the pin printer array type head that moves over the preceding one, in the direction of the lengthwise axis of the paper. The paper is moved in a controlled manner on the table parallel to its lengthwise axis.
Abstract:
A device for holding a Charge Couple Device (CCD) in an optical scanner where optical alignment of the CCD to the position of scanned image of document can be easily made. The device includes a holder for holding a lens and providing a focused image taken from the scanned document; a positioning element mounted on the holder for adapting a CCD to be slightly rotated in a plane around a pivot point fixed on the holder and aligned with the focused image. The positioning element is furnished with a matching hole for precisely carrying a bottom portion of the CCD. The positioning element mounting to the holder needs only one dimensional adjustment which is easier and more effective.
Abstract:
A mechanism for facilitating necessary axial adjustments for an image reader unit with a simple arrangement and operation. The image reader unit 2, on which a sensor 4 and a lens 6 are joined to each other in a specific positional relationship along the optical axis L, is so held by a supporting mechanism 41 that the image reader unit 2 can rotate at the lens side about an axis R of rotation which is parallel to the optical axis L and can swing at the sensor side vertically about a pivotal point P which is located on the axis R. A height adjusting mechanism 42 rotatably supports the image reader unit 2 at the sensor side and adjusts its height, and a tilt adjusting mechanism 43 adjusts the inclination of the image reader unit 2 by rotation around the axis R.
Abstract:
An image size compensating system of a multifunction printer includes a scanning unit to generate scan data obtained by scanning a reference document and a copy of the reference document, a system control unit to extract scan information on widths and lengths of the reference document and the copy from the scan data, and a printer engine to receive the scan information from the system control unit and to control a main motor controlling a length of a print image and a polygon motor controlling a width of the print image so that sizes of the reference document and the copy are identical to each other.
Abstract:
PURPOSE: An apparatus and a method for correcting image of a complex device are provided to self-correct an image in a system automatically by correcting abnormal image data through an image correction table and recording the data in a buffer by reading initial data when a system is initially driven. CONSTITUTION: A printer head module(31) for storing an ink for documenting data prepared in a computer and executing a printing by injecting an ink on a paper in accordance with a controlled printing instruction is mounted at the right side portion of a carriage mechanism(30). A scanner module(32) is mounted to the carriage mechanism(30) for scanning a document. The upper portion of the carriage mechanism(30) having the scanner module(32) and the printer head module(31) is fixed on a guide rail(36), and slides and reciprocates in the left and right directions. The data prepared in a computer are printed by injecting an ink in accordance with a printing instruction through a nozzle of the printer head module(31) or the data to be scanned are scanned through the scanner module(32). In addition, a base sheet(60) being displayed a base line(61) is mounted on the carriage mechanism(30).
Abstract:
A scanning module and an image reading device equipped with the same are provided to realize the scanning module integrated with an image sensor by using the small number of parts and adjust an arrangement state of the image sensor anytime. A frame(501) arranges a light source, a mirror, and a light collecting lens while forming an optical path to scan a document. A base plate(570) is attached with the image sensor(316) receiving the light collected by the light collecting lens. An arrangement member(550) is placed between the light collecting lens and the base plate. An arranger arranges a position and a tilt angle of the image sensor over 5 degrees of freedom by adjusting the position fixing the arrangement member to the frame and the position fixing the base plate to the arrangement member with the first and second adjuster.
