    • A scanner comprises a transparent platen mounted on a housing, and an object-imaging device within the housing mounted for longitudinal movement relative to the platen and an object supported thereby. The object-imaging device is rotatable about a transverse axis and comprises an aperture for receiving light reflected from the object. The object-imaging device has a travel distance between a home end position and a back end position, the travel distance comprising a central portion and at least one end portion. The scanner further comprises a mechanism operatively associated with the object-imaging device for rotating the device about the transverse axis thereof in response to movement of the device within the at least one end portion of the travel distance, the device being rotated in a direction so that the light-receiving aperture is rotated away from the central portion of the travel distance.
    • 扫描仪包括安装在壳体上的透明压板,以及安装在壳体内的物体成像装置,用于相对于压板的纵向运动以及由此支撑的物体。 物体成像装置可以围绕横向轴线旋转并且包括用于接收从物体反射的光的孔。 物体成像装置具有本机端位置与后端位置之间的移动距离,行驶距离包括中心部分和至少一个端部部分。 扫描仪还包括与物体成像装置可操作地相关联的机构,用于响应于装置在移动距离的至少一个端部内的移动而围绕其横向轴线旋转装置,该装置沿着这样的方向旋转 光接收孔径远离行进距离的中心部分旋转。
