A data transfer device for transferring data to a removable data storage item. The body seals to a rocker box top and defines the inlet and outlets. Under the control of the controller 67, a PC card interface 65 stores the still image into a PC card 9 and reads the still image therefrom. The puzzle also preferably includes a case that restrains non-rotational movement of each element and a linkage that forces rotation of all other elements in any one row to rotate about their respective first axes when any one of the elements in that row is rotated about its first axis. A signal input of each group of pass gates is connected to a respective output pin of the driver IC. The apparatus can also have a weight-discriminating device.
