Abstract
The printer is provided with a detection data storage area section comprising sixteen storage areas for storing detection data from a transmission type sensor for every 1-step driving of a feed motor. When the difference between the last detection data and the detection data before steps is a value equal to or more than 0.7 V, the last detection data is set in a gap determination level storage area, is set in a gap flag area, and counting by a gap length counter is started. Thereafter, when the detection data from the transmission type sensor comes to be equal to or smaller than the value set in the gap determination level storage area is set in the gap flag area and the position in the half of the count value of the gap length counter is recognized as the gap center.
