摘要:
A document reading apparatus comprising a document table, a reading section disposed above the document table for reading a document placed on the document table. The reading section includes a sensor for detecting variations of brightness within a selected reading area of the document which is designated by light beams prior to a reading operation. This apparatus further comprises a display device for displaying the image of the selected reading area.
摘要:
In a document reading apparatus capable of picking up image data of documents from above position thereof, curvature of the documents is detected by measuring the height of the document surface. In accordance with the detected curvature, interpolative and expansional processing to the picked up image data is executed. Distorted image data of the documents due to the curvature is thereby corrected.

摘要:
A document reading apparatus comprising a document table, a reading section disposed above the document table for reading a document, e.g. an opened book, placed on the document table, and a linear light source for emitting light to the opened book at an angle thereto. The reading section includes a sensor for detecting an image of the light emitted to the book. This image displays a brightness distribution over surfaces of the opened book including curvatures adjacent the joint. The brightness distribution is used as a reference for rectifying an image signal corresponding to the opened book when the document image is reproduced.
摘要:
A document reading apparatus which can determine an effective image pickup area containing no object such as operator's hands or fingers pressing a document and rectify image data prior to imaging operation, making use of a difference of the object from the document in chromaticity, luminous density, and the like.
摘要:
An image reading apparatus which reads document surfaces of open book-like documents placed on a document platen in a face upward condition, the image reading apparatus comprises; a first detector which detects a height distribution of a document surface in a main scanning direction, a second detector which detects a height distribution of the document surface in a sub-scanning direction, and a direction discrimination device for discriminating whether a placement direction of the document is a main scanning direction or a sub-scanning direction based on the height distributions.
摘要:
An image reading apparatus which reads book-like documents placed on a document platen in a face upward condition. A first detector detects the height of the document surface by the shape of a side surface of the document, and a second detector detects the height of the document by the shape of the document surface. A discrimination device detects abnormal height data detected by the detectors, and distortion of image data output from an imaging device is corrected using height data determined to have no abnormality.
摘要:
In an image reading apparatus in which a document is read with scanning by a image pickup device, a height of the document and an outline of the document are detected. Based on the detected height and outline data, together with a calculating of a document size, an offset amount from a setting reference position of the document is calculated. Based on the calculations, the image is processed properly. Also, if the document is not placed correctly or a degree of an image distortion is not within a correctable range, an alarm is issued.
摘要:
An actuator included in a head substrate of an ink-jet head receives, with an electrode on the surface of the actuator, power fed from the wiring of a wiring substrate arranged opposite the head substrate. A first electrode of the wiring substrate is electrically connected to the wiring, and protrudes to the side of the head substrate. A second electrode is electrically connected to the electrode on the surface of the actuator, protrudes to the side of the wiring substrate and is electrically connected to the first electrode. The head substrate and the wiring substrate are adhered to each other through an adhesive layer such that a space to which the first electrode and the second electrode are exposed is hermetically sealed. The hermetically sealed space is in a vacuum state or is filled with a gas containing a predetermined amount of water or less.
