ABSTRACT:
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.
