A punch data generating device that generates punch data used in an embroiderable sewing machine for punch engraving a pattern on a workpiece by attaching a punch needle that punch engraves a surface of the workpiece in dot-by-dot strokes on a needle bar of the embroiderable sewing machine and moving the punch needle up and down while transferring the workpiece in two predetermined directions by a transfer mechanism. The punch data generating device includes a data generator that generates the punch data so that when punch engraving a plurality of patterns, the patterns are sequentially punch engraved one by one.

Punch data generating device and computer readable medium storing punch data generating program

A multi-needle sewing machine including a plurality of needle bars including a specific needle bar allowing detachable attachment of a punch needle that punch engraves a surface of a punch workpiece in dot-by-dot strokes; a transfer mechanism that allows detachable attachment of a punch workpiece holder a detector that detects the attachment of the punch workpiece holder on the transfer mechanism; and a controller that when the attachment of the punch workpiece holder is detected by the detector, executes a punch engraving operation on the punch workpiece with the punch needle by selecting the specific needle bar and by controlling a needle-bar selector/driver mechanism and the transfer mechanism based on punch engraving pattern data which is pre-stored or given by external components.

Multi-needle embroidery sewing machine

A sewing machine includes a sewing controller that controls sewing machine components, an imaging element capable of capturing facial images of a sewing machine user; a settings storage that stores settings for preset modes, the settings comprising items pertaining to sewing machine functions; a user information storage that stores facial image data of the user captured by the imaging element with mapping to the settings of the mode registered with the user; a verifier that verifies whether or not image data that matches the facial image data captured by the imaging element at sewing operation start exists in the user information storage; and an instruction controller that reads the settings from the user information storage when receiving a positive verification result from the verifier, and that instructs the sewing controller to control the sewing machine components based on the settings read.

Sewing machine and computer readable medium

A sewing machine capable of embroidery sewing is configured to specify a type of embroidery frame by shooting an embroidery frame placed on an upper surface of the bed by a CCD or a CMOS image sensor disposed in an underside of an arm from an obliquely upward direction and obtaining an X-directional size and a Y-directional size of the embroidery frame, an embroiderable area size, and further a height-directional size of the embroidery frame by calculation based on image data shot by the image sensor.
