    Abstract: An image reading device feeds a document original along a sub-scanning direction over an exposure glass. A moving unit moves to and fro in the sub-scanning direction over the exposure glass thereby causing an image reading position on the exposure glass to move. A line image sensor reads one line of an image of the document original at the image reading position in a main scanning direction, while the moving unit is moving, thereby obtaining image. A dirt determining unit determines that there is dirt on the exposure glass when a straight line appears in the main scanning direction in the image data.

    Abstract: A notebook computer that has a document holding function includes an upper cover and a base. The upper cover includes a screen and an image pickup device. The base includes a keyboard and a touchpad. A touchpad chassis is disposed under the touchpad and connected with a bottom surface of the touchpad. A fixing recess is formed in an edge surface of the touchpad chassis for holding the document. A rotatable frame is disposed under the touchpad for overturning the touchpad chassis. As such, a shooting angle is defined between the image pickup device and the document held in the fixing recess.

    Abstract: Motion is introduced into a scanning operation, in addition to the motion that is inherent in any scanning operation. For example, in a flatbed scanner a linear array of scanning devices is positioned across a document in a first or “x” direction and this array is moved across the document in a perpendicular or “y” direction. With embodiments of the present technology a vibratory motion is introduced into the scanning process—not aligned with the basic “y” direction of scan. Such vibratory motion can be controlled in accordance with pre-stored data, or a random process can be employed. In some arrangements, the vibration reduces Moiré patterns. In other arrangements, the vibration causes a hidden pattern to be revealed from the scanned object. A great many other features and arrangements are also detailed.

    Abstract translation: 除了任何扫描操作中固有的运动之外，还将运动引入扫描操作。 例如，在平板扫描仪中，扫描装置的线性阵列沿着第一或“x”方向跨过文件定位，并且该阵列沿垂直或“y”方向移动穿过文件。 利用本技术的实施例，将振动运动引入扫描过程 - 不与扫描的基本“y”方向对齐。 这样的振动可以根据预先存储的数据进行控制，也可以采用随机过程。 在一些布置中，振动减少了莫尔图案。 在其他布置中，振动导致从被扫描物体露出隐藏图案。 还有很多其他功能和安排也很详细。

    Abstract: An image reading apparatus and an image expansion and contraction correcting method are provided that improve the quality of each read image by restraining image expansion and contraction caused by a variation in the combination of conveying units for conveying each document. The image reading apparatus has conveying units (a first conveying unit, a second conveying unit, and a third conveying unit) that convey each document, and an image reading unit (a first image reading unit and a second image reading unit) that reads an image of each document being conveyed by the conveying units. The image reading speed of the image reading unit is adjusted in accordance with a change in the combination of conveying units that are conveying a document, so as to correct image expansion and contraction caused by a change in document conveying speed caused by the change in the combination of conveying units.

    Abstract: An image forming apparatus according to the invention includes: a sensor disposed under an original stand, on which an original is placed, to be in close contact with the original stand; a first light source that irradiates light on a scanning area of the original from a direction obliquely below the original; and a second light source that is disposed in a position opposite to the first light source across the sensor and irradiates light from a direction obliquely below the original opposite to a direction of the light irradiated from the first light source. When the original is not a stuck original, the first light is turned on and, when the original is a stuck original, the first light source and the second light source are turned on. According to the image forming apparatus according to the invention, it is possible to reduce power consumption while preventing occurrence of an original shade of a stuck original in a contact-type optical system.
