The head main body includes nozzles, a nozzle drive unit for driving the nozzles and a head support body for supporting the nozzles and the nozzle drive unit. The head camera unit is fixed to the head support body and has head cameras corresponding to the nozzles respectively for photographing electronic components. The head drives the nozzles to hold the electronic components, transfers the electronic components from the electronic component supply device to the substrate and mounts the electronic components onto the substrate. The control device synthesizes images photographed by the head cameras to generate an image with fields of the head cameras connected together, and determines a process based on the synthesized image synthesized.

B23K 31/12 - Processes relevant to this subclass, specially adapted for particular articles or purposes, but not covered by any single one of main groups relating to investigating the properties, e.g. the weldability, of materials
The sewing machine is provided with: needle plate (40) in which a needle hole (411, 421) through which the sewing needle (11) is inserted is formed; a feed mechanism (60) that serves as a movement mechanism for moving a workpiece along the upper surface of the needle plate (40); a vertical needle movement mechanism (30) for performing vertical movements of the sewing needle (11); a shuttle mechanism (50) for catching the upper thread (U) from the sewing needle (11) below the needle plate (40) and interlacing with the lower thread (D); a thread-cutting device (80) provided between the needle plate (40) and the shuttle mechanism (50) for cutting the lower thread (D) and the upper thread (U); a wiper mechanism (90) for drawing out the sewing needle-side portion (U1) of the upper thread (U), which has been cut by the thread-cutting device (80), to the upper side of the workpiece; a control device (120); and a residual end-excising mechanism (100), which is disposed below the upper surface of the needle plate and above the thread-cutting device. The residual end-excising mechanism excises the residual ends of the lower thread and upper thread that extend from the workpiece after thread-cutting by the thread-cutting device. The residual ends of the upper thread and lower thread are thereby shortened.
A throat plate assembly for a sewing machine, comprising a throat plate extending in a thickness direction from a first surface, for contacting a layer of fabric to be sewn, to a second surface, said throat plate being provided with a needle bore that passes through the thickness of the throat plate, from its first surface to its second surface, for passage of a sewing machine needle, wherein the throat plate assembly further comprises a cutting member, having a cutting edge, that is movable relative to the needle bore from a first position to a second position so as to cut at least one thread received in the needle bore, wherein the cutting member is located relative to the throat plate such that its cutting edge cuts the at least one thread along a cutting plane that is substantially in fine with the second surface of the throat plate or is located between the second surface of the throat plate and the first surface of the throat plate.
