The sewing machine includes an imaging unit, a conveyor portion, a processor, and a memory. The imaging unit has an image capture range, and is configured to capture an image of a holder member. The conveyor portion is configured to convey the holder member relative to the imaging unit in a first and a second direction. The processor performs processes. The processes include causing the imaging unit to capture the image of the holder member that has entered the image capture range. The processes include acquiring first image data that is data of a first image representing the image of the holder member. The processes include identifying a predetermined marker from the first image of the acquired first image data. The processes include determining whether an inclination angle of the holder member exceeds a predetermined value on the basis of a variable acquired on the basis of the identified marker.

The industrial sewing machine includes: a web server, based on a request from a web browser installed on an information terminal, providing the web browser with an operation screen simulating an operation panel, and receiving operation data generated by operating the operation screen; and a sewing machine control part, controlling a sewing machine operating part based on the operation data.

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.

A sewing machine detects a sewing status after a change, when the sewing status changes. When the sewing machine receives a status request requesting the sewing status, from an information terminal via a LAN, the sewing machine transmits, to the information terminal, sewing status information that accords with the detected sewing status. When the detected sewing status satisfies a predetermined condition, the sewing machine transmits a notification request, which includes identification information identifying the information terminal, to a server, in order to cause the server to transmit, to the information terminal, a notification command instructing a push notification in the information terminal.

A sewing-machine operating program is installed in a terminal device of a user. A specifying information acquiring step causes a short-distance information acquiring unit to acquire specifying information recorded on a sewing-machine main unit. In the distance measuring step, an apart distance is calculated from a detection result of a movement detecting sensor with a position where the specifying information is acquired being as an initial position. In the distance comparing step, for a remote operation to the sewing-machine main unit, the apart distance and a prescribed distance are compared. In the function restricting step, when the apart distance is within the prescribed distance, an operation command is transmitted to the sewing-machine main unit via a wireless communication device, and when the apart distance exceeds the prescribed distance, the operation command is not transmitted to the sewing-machine main unit.

A sewing machine that sews an embroidery pattern on a sewing object includes an embroidery frame horizontally moving along a direction which a frame surface extends, a needle bar supporting a needle for inserting a thread, and reciprocally moving toward an internal space of the embroidery frame, a memory unit storing image data of the embroidery frame, and embroidery data of the embroidery pattern, and a display unit displaying an image of the embroidery frame, an image of the embroidery pattern within the image of the embroidery frame, and a feature point with a positional relation between the embroidery pattern, and the embroidery frame when actually sewn in accordance with the embroidery data.

The present invention relates to a method of operating a quilting or sewing machine. In the method, an operator may switch the modes in which the sewing machine is operating. The modes may be switched when the sewing machine is in operation or when the machine is stopped. The modes to which the sewing machine may be switched to and from may be pre-set modes as defined by an operator. The modes that may be switched to and from may include settings for stitch mode and stitch speed. The buttons may be physical buttons associated with the sewing machine's handles, or they may be digital buttons associated with a tablet device.

A sewing machine including a detection portion that detects a movement amount of a workpiece, a sewing machine motor that serves as a driving source for vertical movement of a needle bar, and a control device that controls the sewing machine motor based on the detection result by the detection portion and performs control to maintain a constant stitch pitch. The control device lengthens a period for obtaining an output of the detection portion when the movement amount of the workpiece per unit time based on the detection result by the detection portion is decreased, and shortens the period for obtaining the output of the detection portion when the movement amount of the workpiece per unit time based on the detection result by the detection portion is increased.

A method for identifying reference points in a hand drawing track with a number (n) of dots includes marking a first one of the dots as a reference point; for each of a (k.sup.th) one of the dots, determining an included angle; marking the (k.sup.th) one of the dots as a reference point when the included angle associated therewith is larger than a predetermined angle; calculating an accumulated distance between the (k.sup.th) one of the dots and a last one of the reference point (s) thus marked when the included angle is not larger than the predetermined angle; and marking the (k.sup.th) one of the dots as a reference point when it is determined that the accumulated distance thus calculated is larger than the predetermined distance, 2k(n1).

In one preferred mode, the operator selects by the touch panel 2 a pattern from the displayed patterns on the display 1 and starts the embroidery by operation of the start/stop switch. The CPU 10 is checking the detection signal from the sensor 3 and when the signal is on, the CPU 10 keeps the display 1 in operation. When the operator goes out from the sensor detectable area 60, the signal of the sensor 3 disappears and the CPU 10 generates the LED display 4 indicating the progress of the sewing. Since the operator can see the LED display 4 from the outside of the display visible area 61, the operator recognizes the conditions of the machine A.
