摘要： The invention provides an image reading apparatus and method capable of performing skew error correction at high speed. In an image reading apparatus that conveys a stacked medium along a conveyance path, reads an image of the medium being conveyed, and discharges the medium after reading the image, the apparatus comprises calculation means for calculating the amount of skew of the medium while being conveyed, and correction means for correcting the amount of skew of the medium in accordance with the amount of skew calculated by the calculation means. The correction means comprise determination means for determining whether correction for the amount of skew should be performed or not, and control means for correcting the amount of skew of the medium. The calculation means comprise medium detection means for detecting the state of the medium conveyed along the conveyance path, and calculate the amount of skew from the detected result of the state of the medium. The control means comprise correction control means for correcting the amount of skew based on the amount of skew of the medium calculated by the calculation means when the determination means determine to correct the amount of skew. The calculation means comprise image reading means for reading an image of the medium conveyed along the conveyance path at a position closer on the conveyance path to the discharging side than the medium detection means, and calculate the amount of skew from the image data of the medium read by the image reading means.

摘要： An apparatus having an ink-jet head has a time measuring unit, a recording unit, and a prefiring operation control unit. The time measuring unit is used to measure an elapsed time from execution of prefiring operations for the ink-jet head, and the recording unit is used to record whether or not printing nozzles disposed in the ink-jet head are operated. The prefiring operation control unit determines a number of prefiring operations in accordance with a measurement result obtained by the time measuring unit and operated conditions of the printing nozzles recorded in the recording means, and executes prefiring operations for the ink-jet head. Therefore, the apparatus is capable of executing prefiring operations often enough and sufficient for the actual operated conditions of the printing nozzles disposed in the ink-jet head, and thereby preventing ink from being consumed at enhanced rate by useless prefiring operations.

摘要： An image scanner-reader has an image read unit, and an employing control unit. The image read unit is used to read an original document and provide image data of the original document. The employing control unit is used to control the relative moving speed between the original document and the image read unit, and when an original document reading operation is suspended, the employing control unit controls the restart of the reading operation after decreasing the relative moving speed to a slow reading speed of the original document. Therefore, when the image data buffer becomes full enough to cause a suspension state, and the read operation is restarted after changing control conditions, so that the quantity of data transferred to the image data buffer is reduced. Namely, according to the present invention, the number of occurrences of the suspension state can be greatly reduced, and thereby the overal reading speed can be improved without increasing the data receiving speed of a host device.
摘要翻译：图像扫描器读取器具有图像读取单元和采用控制单元。图像读取单元用于读取原始文档并提供原始文档的图像数据。采用控制单元用于控制原稿与图像读取单元之间的相对移动速度，并且当暂停原稿读取操作时，采用控制单元在相对移动速度降低之后控制读取操作的重新开始原始文件的阅读速度慢。因此，当图像数据缓冲器变得足够充分以引起暂停状态时，并且在改变控制条件之后重新开始读取操作，从而减少传送到图像数据缓冲器的数据量。也就是说，根据本发明，可以大大减少暂停状态的发生次数，从而可以在不增加主机设备的数据接收速度的情况下提高外部读取速度。

摘要： A cut sheet feeding device having a function of detecting a skew of the sheet to be fed is incorporated in an image reader, a printing apparatus, etc. The cut sheet feeding device is capable of surely detecting the skew of a document without an operator visually monitoring the same. The cut sheet feeding device has size sensors corresponding to standard sheet sizes, respectively, for detecting the size of a document that is being fed along a feeding path. The detected document size is compared with a set document size stored in advance. If the detected document size is greater than the set document size, it is determined that there is an abnormality in feeding the document. The cut sheet feeding device also has a document passage detector for detecting the passage of the document. The outputs of the document passage sensor and size sensor are compared with each other, to calculate a skew of the document that is being fed. This skew is used to determine whether or not the document is being fed normally.

The ADF mechanism can be set at an arbitrary position with an arbitrary orientation for use, whereby convenience for the user is improved while ensuring freedom with regard to the setting place of the apparatus. Further, the scanner apparatus is made such that reading with the ADF unit and reading with the flatbed unit can be performed simultaneously. A movable coupling mechanism is provided at a joint portion between the ADF mechanism and the flatbed mechanism. The movable coupling mechanism does not fix the position and orientation of the ADF mechanism and enables the ADF mechanism to be freely moved and rotated. With this movable coupling mechanism, the ADF mechanism can be disposed at either of the left and right ends of the paper-pressing board of the flatbed unit or at an arbitrarily position in consideration of convenience for a user and the setting place of the apparatus. Further, the orientation of the shooter of the ADF mechanism can be freely changed.
