Claims (1)

[Claims for Utility Model Registration] A one-dimensional image sensor scans the original by sliding it, main scans it line by line, and sub-scans it in the sliding direction to repeatedly read the image to create a serial image. In an image reading device that obtains data and a detection signal for each predetermined displacement amount of the sliding scan, a signal generation that generates a first signal representing the beginning of the main scan and a second signal of the synchronization signal in the sub-scan direction. a calculation unit that calculates the scanning speed in the sub-scanning direction by calculating the state of the second signal within a predetermined period of the first signal; and a calculation unit that corresponds to the scanning speed in the sub-scanning direction by the calculation unit. An image reading device configured to include: a display unit that displays images at predetermined stages;
