Abstract (en)

A sewing machine (100) includes a cloth feeding mechanism (20) configured to feed a workpiece (CU, CD) in a cloth feeding direction, a lateral-feeding mechanism (30, 36) configured to move the workpiece (CU, CD) in a seam allowance direction (X), cloth edge detection means (40, 60) for detecting a side edge portion of the workpiece (CU, CD) along the cloth feeding direction (Y), a controller (13) configured to control the lateral-feeding mechanism (30, 36) to control a seam allowance of the workpiece (CU, CD). The cloth edge detection means (40, 60) includes a light source (431, 631) for irradiating a reflector plate (12), a detector (45, 65) having a plurality of light receiving devices arranged along the seam allowance direction (X) to receive the light reflected by the reflector plate (12) and optical means (44, 64, 632) for collimating the light emitted by the light source (431, 631) and for directing the collimated light in a direction orthogonal to the seam allowance direction (X) and inclined with respect to the cloth feeding direction (Y) toward the reflector plate (12) to irradiate the reflector plate (12) over a range along the seam allowance direction (X).
