    • An image reading apparatus reads imae data from an original document when a carriage supporting a line image sensor reciprocates along an original document. When the image reading apparatus is transported, the carriage is secured to the apparatus so that it will not be moved due to vibrations and impacts. A safety device is installed on the reading apparatus so that the apparatus may not be operated with the carriage secured. The safety device checks whether or not the carriage is secured by use of a switch. When the carriage is secured, the safety device turns off the power supplied to the carriage. The safety device also turns off the power supplied to the light source when the carriage securing cover is removed to replace the light source.
    • 当支撑行图像传感器的托架沿着原始文档往复运动时,图像读取装置从原始文档读取imae数据。 当图像读取装置被传送时,托架被固定到装置上,使得它不会由于振动和冲击而被移动。 在读取装置上安装有安全装置,使得装置可能不会在支架固定的情况下操作。 安全装置通过使用开关检查托架是否被固定。 当滑架固定时,安全装置关闭提供给滑架的电源。 当拆卸托架固定盖以更换光源时,安全装置也会关闭提供给光源的电源。
