Abstract
A bread maker includes upper and lower rollers and a bar code scanner. The upper and lower rollers wind a mixing bag containing bread ingredients to form dough. The bar code scanner reads a bar code attached to the mixing bag so that, as the mixing bag is wound by rotation of the upper and lower rollers, the bar code scanner reads the bar code while being in contact with the bar code wound around one of the upper and lower rollers. The upper roller includes flat and arcuate portions. The flat portion is provided with an arcuate guide section to form a circular track together with the arcuate portion.
