Abstract: 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.

Abstract: A sorting apparatus for a solid waste sorting system has a first set of three belt conveyors, for conveying solid waste at a first speed, and a second set of three belt conveyors, each of the latter disposed with one end connected to the downstream end of a corresponding one of the first three belt conveyors, for conveying solid waste at a second speed which is greater than the first speed. The first three belt conveyors extend transversely into a feed-out path of a storage section in such a way that the conveyor lying successively furthest away from the storage section along the feed-out path is of successively longest upstream-end extension. The solid waste is sorted manually on the second set of three belt conveyors and is then supplied to a draft-sorting machine.
