摘要： An image reading device includes a clock generator, an image sensor, a plurality of switches having a first switch and a second switch, a reader, a first controller, and a second controller. The clock generator generates a first clock signal having a first cycle and a second clock signal having a second cycle shorter than the first cycle. The image sensor detects an image formed on a document to generate an image signal. The image signal is inputted into the first switch and the second switch by rotation. The first switch and the second switch is capable of switching to simultaneously or alternately output the image signal in synchronization with the first clock. The reader reads the image signal outputted from the first switch and the second switch. The first controller controls the first switch to output the image signal to the reader during a first period and to control the second switch to output the image signal to the reader during a second period. The second controller controls the clock generator to generate the first clock signal during the first period and the second period and to generate the second clock signal during a third period that is between the first period and the second period and that is longer than a predetermined period mT and shorter than (k×T1) The T1 is the first cycle. The k is a minimum integer that satisfies mT

摘要： PROBLEM TO BE SOLVED: To provide an original read method by which originals comprising mixed color originals and black/white originals are read at a high-speed by using an image reader provided with a carrying means to set the originals carried by a paper feed means to a prescribed position on a platen.
SOLUTION: The image reader comprises a feed means that feeds originals on a paper feed tray, a carrying means that carries the original onto a platen, an optical read means that reads image data of the original on the platen under the platen, an identification means that identifies the type of image data of the original read by the optical read means, and a control means that controls each means above. The control means discharges the original when the image data are of a 1st type and outputs the first image data in a 1st read mode, or reads the original in a 2nd read mode different from the 1st read mode as its control when the image data are of a 2nd type.

摘要： A beam light scanning device includes an image data processing unit operable to output image-processed data of neighboring pixels in such a way that the data is divided for distribution into first pixel data and second pixel data. The scanner also includes a synchronizer circuit that receives the first and second pixel data as output from the image data processor and outputs these pixel data while letting them be synchronized with clocks as synchronized based on a horizontal synchronous signal. The scanner further includes a couple of pulse width modulators or "PWMs", a synthetic circuit, and a laser diode module. The PWMs are for adjustment of the pulse widths of the first and second pixel data as output from the synchronizer circuit respectively. The synthetic circuit combines together the pulse width-adjusted first and second pixel data. The LD emits a light beam indicative of the resultant combined pixel data.

摘要： PROBLEM TO BE SOLVED: To increase productivity in consecutive scanning with secured image quality on the occasion of shading correction in an original sheet document scanning mode. SOLUTION: Before scanning one sheet of original document 50 carried onto a carried original document scanning glass 6 by original document automatic feeding means in the original sheet document scanning mode; optical scanning systems 10, 13 are moved to the side of a reference white plate 7, and a reference white plate 7 is scanned in a return direction toward the side of the carried original document scanning glass 6. In this way, it is necessary to beforehand acquire a black offset data of a reference of image data before scanning the reference white plate 7 on the occasion of shading correction in the original sheet document scanning mode, but it is possible to reserve a sufficient period of time until acquiring a white level after acquiring a black level, thus leading to possibility of operation even with a limited interval time between paper sheets. Therefore, it is possible to reduce the interval time between paper sheets as compared to a conventional system, and thus improvement of the productivity is achieved. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：在原始薄片原稿扫描模式中的阴影校正的情况下，以确保的图像质量来提高连续扫描的生产率。
解决方法：在原始文件扫描模式下，将原稿文件自动进纸装置扫描一张原件50送到携带的原稿扫描玻璃6上之前; 光学扫描系统10,13移动到参考白板7的侧面，并且在返回方向上朝向被携带的原稿扫描玻璃6的侧面扫描参考白板7.这样，必须在原稿张文档扫描模式中，在阴影校正的情况下，预先获取扫描参考白板7之前的图像数据的参考的黑色偏移数据，但是可以保留足够的时间段直到获得白色电平获得黑色电平，从而即使在纸张之间的间隔时间有限的情况下也可能进行操作。因此，与常规系统相比，可以减少纸张间隔时间，从而实现生产率的提高。版权所有（C）2007，JPO＆INPIT

摘要： In a control device, the scan control unit controls a scanning operation in which data is to be generated by reading a document. The data format selecting unit selects one of a first format or a second format different from the first format as a data format in which the data is to be generated. The resolution setting unit sets a reading resolution based on the data format. The resolution setting unit sets a first resolution as the reading resolution when the data format selecting unit selects the first format whereas the resolution setting unit sets a second resolution different from the first resolution as the reading resolution when the data format selecting unit selects the second format. The scan control unit controls the scanning operation to read the document in the reading resolution set by the resolution setting unit.

摘要： PROBLEM TO BE SOLVED: To provide a technique capable of performing scan at appropriate scan resolution.SOLUTION: A controller for controlling a scan performance part for scanning a manuscript includes format determination means and scan control means. The format determination means determines whether the format of data to be obtained by scan is the first format or the second format different from the first format. The scan control means determines scan resolution in accordance with the format of the data and allows the scan performance part to perform scan at the scan resolution. Specifically, in a first case where the format of the data is determined to be the first format, first scan resolution is determined as the scan resolution. In a second case where the format of the data is determined to be the second format, second scan resolution is determined as the scan resolution.
