20090039594 | IMAGE FORMING APPARATUS - An image reading apparatus includes a sheet feeding unit configured to sequentially feed a plurality of documents loaded on a document positioning plate, a reading sensor arranged in a conveyance path configured to read a document of the plurality of documents fed by the sheet feeding unit, an acquisition unit configured to acquire an interval of the document between a trailing edge of a preceding document and a leading edge of a next document conveyed through the conveyance path, and a reading unit configured to execute a first reading mode using the reading sensor to read the document conveyed at a first conveyance speed, and a second reading mode using the reading sensor to read the document conveyed at a second conveyance speed that is lower than the first conveyance speed, wherein the reading unit executes the second reading mode after the first reading mode when the interval of the document is less than a predetermined interval. | 02-12-2009 |
20090040572 | IMAGE READING APPARATUS - An image reading apparatus includes a document reading and conveying unit, a pressing plate capable of moving to a position to press a document against a reading surface and to a position withdrawn from the reading surface, and a fixed reader configured to read a document fixed on the reading surface by moving a close-coupled image sensor relative to the document. The document reading and conveying unit includes a controller configured to perform pickup initialization of returning a pickup roller to an initial position after the completion of conveying one or more documents and is supported by the pressure plate. The controller includes a first timer configured to measure an elapsed time from the completion of reading performed by the fixed reader. The controller performs the pickup initialization after a measurement value measured by the first timer exceeds a first time. | 02-12-2009 |
20090302520 | IMAGE PROCESSING APPARATUS - The invention provides an image processing apparatus capable of stopping the transport of a sheet when an access cover is opened to prevent the damage of the sheet, without additionally providing a sensor. An image processing apparatus includes: a transport member for transporting a sheet through an image processing unit; a driving mechanism for transmitting a driving force to the transport member; an access cover for opening a portion of a sheet transport path; and a driving switching unit for transmitting the driving force of the driving mechanism or cuts off the transmission of the driving force in operative association with the opening or closing of the access cover. The driving switching unit cuts off the transmission of the driving force to the transport member when the access cover is opened. | 12-10-2009 |
20110310445 | IMAGE READING METHOD AND IMAGE READING APPARATUS - A method includes a first step, a second step, and a third step. In the first step, a fed document is returned to an upstream side of a reading unit by reversing the document after a first passage through the reading unit. In the second step, the document returned in the first step is returned to the upstream side of the reading unit by reversing the document after a second passage through the reading unit. In the third step, the document returned in the second step is passed through the reading unit, and then the document is discharged. | 12-22-2011 |
20130188230 | IMAGE FORMING APPARATUS - An image reading apparatus includes a sheet feeding unit configured to sequentially feed documents loaded on a document positioning plate, a reading sensor configured to read a document of the plurality of documents fed by the sheet feeding unit, an acquisition unit to acquire an interval of the document between a trailing edge of a preceding document and a leading edge of a next document conveyed through the conveyance path, and a reading unit to execute a first reading mode using the reading sensor to read the document conveyed at a first conveyance speed, and a second reading mode using the reading sensor to read the document conveyed at a second conveyance speed that is lower than the first conveyance speed, wherein the reading unit executes the second reading mode after the first reading mode when the interval of the document is less than a predetermined interval. | 07-25-2013 |
20130193635 | FEEDING APPARATUS - A feeding apparatus which is capable of increasing the number of stacked sheets without increasing a size of an apparatus is provided. The feeding apparatus includes a stopper member which is in contact with a leading edge of a sheet placed on a sheet stacking plate and blocks the sheet from entering a separation unit, and an actuating member which presses the stopper member in conjunction with a rotation of a holding member, and a movement distance of the actuating member is longer than a movement distance of the holding member. | 08-01-2013 |
20130194341 | CONVEYING DEVICE AND PRINTING APPARATUS - Provided are an image scanning device that can prevent a rise in the temperature and overloading or overheating of a conveying motor during continuous conveying of document sheets, and a conveying device that includes the image scanning device. According to the present invention, the temperature of a drive motor and the temperature of the periphery of the drive motor are predicted, and based on the predicted values, the conveying mode is selected. | 08-01-2013 |
20130194599 | READING APPARATUS - A reading apparatus includes an auto document feeder configured to be openable and closable around a hinge with respect to a unit including an image sensor. The auto document feeder includes a roller configured to move a document relative to the image sensor, a motor, a gear train configured to transmit a rotation of a rotational shaft of the motor to the roller, and an encoder unit configured to detect rotation information of the motor, and including a sensor and a code wheel. An orientation of the rotational shaft is substantially parallel to a rotational axis of the hinge, and the gear train is arrayed in a direction of an extension of the rotational shaft. A gear that is a part of the gear train is attached to one end of the rotational shaft, and the code wheel is attached to the other end thereof. | 08-01-2013 |
20130194600 | READING APPARATUS AND READING CONTROL METHOD - A reading apparatus includes an image sensor, a movement mechanism including a motor that relatively moves between a document and the image sensor, an encoder that detects information about the relative movement, and a control unit that controls driving of the motor and reading by the image sensor based on the detection by the encoder, wherein when a read-suspension event occurs during the reading, the control unit performs control such that the reading is continued while decelerating the motor, a relative position of a last read pixel with respect to a read position by the image sensor is monitored based on the detection by the encoder, and the driving of the motor is stopped when the read position is determined to reach a stop position set within the last read pixel, and the motor is driven again to resume the reading with a pixel next to the last read pixel. | 08-01-2013 |
20150055198 | IMAGE READING DEVICE AND IMAGE READING METHOD - An image reading device includes: a sensor unit; a first reading part at which the sensor unit reads a document through a first transparent member; a second reading part at which the sensor unit reads a document through a second transparent member different from the first transparent member; and a color reference, wherein measurement of the color reference is able to be performed through the first transparent member by the sensor unit for calibration for reading at the first reading part, and measurement of the color reference is able to be performed through the second transparent member by the sensor unit for calibration for reading at the second reading part. | 02-26-2015 |
