The machine has a roller drive (17) that carries the coupon past a reader, and a processor that converts the information read from the coupon to a digital format for transmission to a central computer. The reader has an image detector (15), of elongated shape, suspended in a box (1,2,3) with its end mountings (20,21) attaching it to the frame of the machine. The reader extends the width of a coupon, and is elastically mounted so that it is held against the roller as the coupons pass through. The image data is then converted to a digitally encoded form.
