Abstract
A medium tracking bar is incorporated into an imaging device for preventing wrinkles or buckling of a medium strip sliding over and touching the medium tracking bar, the medium tracking bar being centrally pivoted to the imaging device by a connecting piece and being centrally pivoted by an elastic element to allow the medium tracking bar to swing like a teeter-totter board in any direction to counteract an uneven stress problem on the medium strip due to a misalignment of the medium strip and to realign the medium strip when it passes through the device thereby to prevent wrinkles or buckling of the medium strip.
