Abstract: An image reading device includes a light source, an imaging element and a control unit. The light source irradiates light on a document. The irradiated light of the light source reflected by the document is incident on the imaging element. The control unit is configured to, if the document is an ordinary document having no light-emitting screen, set a light amount of the irradiated light of the light source at a predetermined reference value and is configured to, if the document is a special document having a light-emitting screen, reduce the light amount of the irradiated light of the light source to become lower than the reference value.

Abstract: A scanner has a movable carriage, a contact image sensor located on the carriage, and a platen that is substantially transparent to visible light overlying the carriage and the contact image sensor. The scanner is selectively configurable between a first scanning mode for scanning substantially opaque media positioned on the platen and a second scanning mode for scanning media substantially transparent to visible light underlying the platen. At least one image on the substantially opaque media is located within a depth of field of the contact image sensor when the substantially opaque media is positioned on the platen. At least one image on the media substantially transparent to visible light is located within the depth of field of the contact image sensor when the media substantially transparent to visible light underlies the platen.

Abstract: It is an object of the present invention to provide an excellent image reading apparatus that realizes miniaturization and reduces a total reading time at the time of reading a transparent original and, in addition, improves operability. In order to attain this object, since the image reading apparatus has a configuration in which a light source driving circuit section is disposed to overlap in the upward direction separating from an original mounting surface of a surface light emitting section, an area occupied by the light source driving circuit section and the surface light emitting section on a horizontal surface becomes small and miniaturization can be realized. In addition, since the light source driving circuit section and the surface light emitting section can be disposed in a position close to a hinge section altogether, the center of gravity of an FAU is moved to the hinge section side, and rotatability of the hinge section becomes easy and is improved. Since an image reading unit has its hinge section side as an HP, a time taken by the image reading unit for moving from the HP to below the surface light emitting section, where a transparent original is disposed at the time of starting to read the transparent original, can be reduced.

Abstract translation: 本发明的目的是提供一种在读取透明原稿时实现小型化并减少总读取时间的优异图像读取装置，并且还提高可操作性。 为了实现该目的，由于图像读取装置具有其中光源驱动电路部分被布置为在与表面发光部分的原始安装表面分离的向上方向上重叠的构造，所以由光占据的区域 源极驱动电路部和水平面上的面发光部变小，能够实现小型化。 此外，由于光源驱动电路部分和表面发光部分可以一起设置在靠近铰链部分的位置，所以FAU的重心被移动到铰链部分侧，铰链部分的可旋转性 变得容易和改进。 由于图像读取单元具有其铰链部分侧作为HP，所以图像读取单元在从开始读取透明度时从HP移动到表面发光部分以下的透明原稿所在的时间 原来可以减少。

Abstract: A scanner includes a first shaft, a second shaft, a photoelectric sensor for scanning a medium to produce an image, a movable carriage positioned on the first shaft for carrying the photoelectric sensor, a movable light source module positioned on the second shaft for generating a light beam for the medium, a driving module coupled to the carriage for driving the carriage to move a first offset along the first shaft, and a locking module coupled to the light source module and the carriage. As the carriage moves with the first offset, the carriage ensures the light source module moves a second offset along the second shaft through the locking module.
