    • A semiconductor device in which an IGBT region and a diode region are formed on one semiconductor substrate is disclosed. The IGBT region includes: a body layer of a first conductivity type that is formed on a front surface of the semiconductor substrate; a body contact layer of the first conductivity type that is partially formed on a front surface of the body layer and has a higher impurity concentration of the first conductivity type than the body layer; an emitter layer of a second conductivity type that is partially formed on the front surface of the body layer; a drift layer; a collector layer; and a gate electrode. In the semiconductor device, a part of the body contact layer placed at a long distance from the diode region is made larger than a part of the body contact layer placed at a short distance from the diode region.

    • An image reading apparatus includes a lower unit, an upper unit arranged above the lower unit and a guide arranged on an opposite side to the lower unit with respect to the upper unit. The guide relatively rotates with respect to the upper unit in a direction away from the upper unit so as to form an ejection path, between the upper unit and the guide, of a sheet-like medium conveyed between the upper unit and the lower unit. The upper unit and the guide are close to each other respectively, at positions closest to the lower unit in respective rotation ranges of relative rotation with respect to the lower unit. The rotation range of the guide is wider than that of the upper unit, in a rotation direction away from the lower unit from the positions close to each other.
    • 图像读取装置包括下部单元,布置在下部单元上方的上部单元和相对于上部单元布置在下部单元的相对侧上的引导件。 引导件相对于上部单元在远离上部单元的方向上相对旋转,以便在上部单元和下部单元之间传送的片状介质之间形成在上部单元和引导件之间的排出路径。 上部单元和引导件在相对于下部单元的相对旋转的相应旋转范围内分别靠近彼此靠近下部单元的位置。 引导件的旋转范围比上部单元的旋转范围在远离下部单元的旋转方向远离彼此靠近的位置。
