Abstract: A checkout device includes first and second stationary scanners forming central portions of first and second scanning lanes set in parallel with each other, each for reading an article code affixed to an article which is moved from an upstream side to a down stream side in a corresponding scanning lane, and a settlement section arranged between the first and second scanning lanes for performing a settlement process based on article codes sequentially supplied from each of the stationary scanners. In particular, the checkout device further includes a position adjusting mechanism for variably setting a position of the settlement section along the first and second scanning lanes.
