Sewing machine
In a sewing machine, an arm includes, on one side thereof in a first direction, a head. A needle bar is disposed at the head to reciprocally move in a second direction. A feed mechanism feeds a workpiece from one side toward the other side of the head in a third direction. The projection unit disposed at the head projects a projection image toward a bed. The projection unit includes an emitter for projecting image light of the projection image. The photographing unit disposed at the head captures a photographing target. The photographing unit includes an incident portion on which light reflected by the photographing target is incident. The emitter and the incident portion are disposed further toward the one side of the arm in the first direction than the needle bar, and further toward the one side of the head in the third direction than the needle bar.
1. A sewing machine comprising:
a bed;
an arm extending in a first direction and including, on one side thereof in the first direction, a head;
a needle bar disposed at the head and configured to receive a needle and reciprocally move in a second direction orthogonal to the first direction;
a feed mechanism configured to feed a workpiece, from one side toward the other side of the head, in a third direction orthogonal to the first direction and the second direction;
a projection unit disposed at the head and configured to project a projection image toward the bed, the projection unit including an emitter from which image light of the projection image is emitted; and
a photographing unit disposed at the head and configured to capture a photographing target, the photographing unit including an incident portion on which light reflected by the photographing target is incident,
wherein a photographing area of the photographing unit on the bed is larger than a projection area by the projection unit on the bed.
2. The sewing machine according to claim 1 , wherein the photographing area is overlapped with the projection area.
3. The sewing machine according to claim 2 , wherein an outer edge of the projection area at the other side in the third direction is closer to the needle bar than an outer edge of the photographing area at the other side in the third direction.
4. The sewing machine according to claim 2 , wherein the outer edge of the projection area and the outer edge of the photographing area are disposed at the other side further than the needle bar in the third direction.
5. The sewing machine according to claim 2 , further comprising a presser bar,
wherein the outer edge of the projection area is disposed between the needle bar and the presser bar in the third direction, and
the outer edge of the photographing area is disposed at the other side further than the presser bar.
6. The sewing machine according to claim 2 , the projection area and the photographing area include a needle plate or a position on the bed where the needle bar moves down.
