<p>The present invention relates to a cloth edge position detecting device and a sewing machine. The cloth edge position detecting device includes a cloth edge sensor (6) configured to output a voltage corresponding to a cloth edge position and a control section (71, 72) configured to detect the cloth edge position based on the voltage output from the cloth edge sensor (6). The control section (71, 72) determines that a position (Pos) at which a voltage change exceeding a cloth edge determining threshold (Ve) appears first in the direction from the inner side to the outer side of the workpiece cloth (W) across the cloth edge is the cloth edge position.</p> |
