摘要： 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.

摘要翻译： 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，所以图像读取单元从HP移动到表面发光部下方所花费的时间，在开始读取透明度时，设置透明原稿 原来可以减少。

摘要： A real image type finder optical system includes an objective lens group having positive refracting power and an eyepiece lens group having a positive refracting power. The objective lens group includes a first group consisting of a negative lens, a second group consisting of a positive lens, a third group consisting of a positive lens and a fourth group having a negative refracting power and forming part of an image inverting optical system. Upon zooming from a wide-angle end to a telephoto end, the first and fourth groups remain fixed and the second and third groups move. The eyepiece lens group comprises a fifth group that forms part of the image inverting optical system and a sixth group having positive refracting power. The resulting real image type finder optical system satisfies specific conditions with respect to the back focus of the first to third groups at the wide-angle end.

摘要： In a coaxial cable comprising a cylindrical conductor tube structure, a cylindrical core conductor arranged within the conductor tube structure, and a dielectric member provide between the conductor tube structure and the core conductor, the conductor tube structure is constituted by a cylindrical outer conductor and a cylindrical inner conductor provided within the outer conductor in coaxial and radially spaced relationship with the outer conductor to be capacitively coupled with the outer conductor. The inner conductor has a first axial end portion protruded axially outwardly from one end of the outer conductor and a second axial end portion received in the outer conductor retracted axially inwardly from the other end of the outer conductor. The outer and inner conductors of the conductor tube structure are thermally insulated from each other thereby reducing heat transmission between the outer and inner conductors without lessening conductivity for high frequency signals.
