A sewing machine includes a first image acquisition unit, a second image acquisition unit, and a display unit. In the sewing machine, the first image acquisition performs image acquisition from the front face side of a cloth for a stitching pattern formed in the cloth. The second image acquisition unit performs image acquisition from the back face side of the cloth such that the center position of the acquired image matches the center position of the image of the stitching pattern acquired by the first image acquisition unit. The display unit displays, on the same screen, a first stitching pattern video image thus acquired by the first image acquisition unit and a second stitching pattern video image thus acquired by the second image acquisition unit.

The present disclosure assists in searching for a specific apparatus among a plurality of apparatuses installed in an installation area. The electronic device includes: a storage portion, installation information for indicating a relationship between position information and a communication apparatus, where the position information is position information of a plurality of installation apparatuses installed in an installation area, and the communication apparatus is associated with the installation apparatus; a communication portion configured to receive an advertising signal transmitted by the communication apparatus installed in the installation area; an estimation portion configured to estimate a relative position between a device body and the installation apparatus associated with the communication apparatus based on identification information of the communication apparatus and the installation information included in a received advertising signal; and a display control portion configured to display causes relative position information on a display portion, and the relative position information is capable of identifying the estimated relative position between the device body and the installation apparatus.

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.

A sewing machine sews a sewing pattern on a work cloth. The sewing machine includes a storage portion configured to store pattern data used for sewing the sewing pattern on the work cloth, and a projector configured to project an image. The sewing machine generates, on the basis of the pattern data, a projection image that includes a pattern object and a peripheral object. The pattern object represents the sewing pattern. The peripheral object is disposed adjacent to an outer edge of the pattern object and surrounds the pattern object. The sewing machine controls the projector and projecting the generated projection image toward a top surface of a bed portion on which the work cloth is placed.

The sewing machine includes a projector and a controller. The controller determines a sewing area inside an embroidery hoop such that the sewing area is greater than a projection area where the projector projects a projection image. The controller determines an embroidery pattern and a position of the embroidery pattern located relative to the sewing area. The controller determines, in the sewing area, a target area corresponding to the projection area. The controller generates projection image data representing a part or a whole, which falls in the target area, of the embroidery patter relative to the sewing area, and controls the projector to project a projection image based on the projection image data after moving the embroidery hoop.

A controller of a sewing machine acquires sewing data for forming a utility pattern continuously in a first direction, acquires a condition for sewing a tapering pattern including a tapering portion, generates a projection image representing the tapering pattern based on the sewing data and the condition, controls a needle bar, a feed dog, and an actuator in accordance with the sewing data to sew the utility pattern continuously in the first direction, after starting sewing of the utility pattern, controls a projector to project the projection image at a planned sewing position of the tapering pattern in a planned sewing size, and performs a tapering pattern sewing operation of, after starting projection of the projection image, controlling the needle bar, the feed dog, and the actuator in accordance with the sewing data and the condition to sew the tapering pattern that is continuous with the utility pattern.

A sewing machine includes a sewing pitch setup unit configured to set up a given sewing pitch; a movement detection unit configured to detect a movement of a material to be sewn; a control unit configured to calculate a movement speed of the material on the basis of a movement amount of the material detected by the movement detection unit and to calculate a rotational rate for a sewing machine motor for operating a needle on the basis of the movement speed and the given sewing pitch; and an informing component configured to inform of magnitude of the rotational rate relative to a maximum rotational rate for the sewing machine motor.

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.

A non-transitory computer-readable storage medium stores a display program including a set of program instructions for a display apparatus. The display apparatus includes a camera, a display, and a controller. The set of program instructions, when executed by the controller, causes the display apparatus to perform: acquiring a shot image representing a real space, the shot image being an image shot by the camera; acquiring target information indicating a thread spool of a detection target; detecting a thread spool position on the shot image for the thread spool of the detection target, based on the shot image and the target information; generating a display image based on the shot image, the display image indicating the thread spool position; and displaying the display image on the display.

The sewing machine includes an image capturing portion, a processor, and a memory. The memory is configured to store computer-readable instructions. The computer-readable instructions, when executed by the processor, cause the sewing machine to perform operations of: setting a specified range within the image capture enabled range based on a first image, acquiring a plurality of partial images, and creating a composite image by combining the acquired plurality of the partial images.
