画像読取装置。[Claims for Utility Model Registration] 1. A line image sensor that performs main scanning in the direction in which a plurality of elements are arranged in parallel is manually moved in a sub-scanning direction perpendicular to the main scanning direction, and once in relation to the movement. In a manual sub-scanning type image reading device that reads an image line by line based on a signal from a speed detection section outputted to perform main scanning, the signal of one line of the image read based on the signal from the speed detection section. An image correction unit that, when a signal from the next speed detection unit is obtained while the processing is not completed, compensates for one line of image to be read based on the signal with one line of image read based on the previous signal. A manual sub-scanning image reading device comprising: 2. A utility model as set forth in claim 1, which is provided with means for issuing an alarm when a signal from the next speed detection unit is obtained while the signal processing of the image of one line that has been read is not completed. A manual sub-scanning image reading device.
