Claim:
1. A sheet feeding device that performs sheet feeding by feeding out and cutting a continuous medium, comprising: a carrying part that is configured to perform a carrying process to carry the continuous medium; a detection part that is configured to detect a leading edge of the continuous medium in a carrying direction and to detect a length over which the continuous medium has been carried from a detected position; a trailing edge detection part that is arranged on an upstream side of the detection part in the carrying direction of the continuous medium and is configured to detect a trailing edge of the continuous medium, the trailing edge being determined from the leading edge with a length specified by a user; a cutting part that is arranged between the detection part and the trailing edge detection part, and is configured to selectively perform a cutting process to cut the continuous medium and a perforation process to form a line of perforations in the continuous medium, wherein a controller that is configured to communicate and control the detection part, the trailing edge detection part and the cutting part, assuming that a minimum length of the continuous medium that is carried by the carrying part is L if L the controller causes the detection part to detect a position that corresponds to L the controller causes the cutting part to be actuated to perform the perforation process to form the line of perforations in the continuous medium at the position that is detected by the detection part and that corresponds to L
