Systems and techniques for image based bar code scanning are described. A rotating spinner (122) is positioned to reflect images to an imaging device (108) within the scanner (100) so that a field of view of the scanner (100) encompasses images reflected by the spinner (122) to the imaging device (108). The rotation of the spinner (122) causes the field of view of the scanner (100) to change. Fixed mirrors (126,128,130;136,138,140) positioned and oriented to reflect images to the spinner (122) and from the spinner (122) to the imaging device (108) further shift the field of view of the scanner (100) as the rotating spinner (122) causes images reflected from different mirrors to be delivered to the imaging device (108).
