Disclosed is a method for producing a sewing data file using an embedded computer. A method for producing a sewing data file of a sewing machine allows the embedded computer to perform the following processes: receiving a color of a thread mounted on the sewing machine through the touch input device and the data input device; receiving an image data through the network device; extracting a color component from the image data by referring to a color of a thread mounted on the sewing machine using the sewing data conversion program; and calculating a ratio occupied by a color of a minimum unit pixel for each separated color as an area occupied by a thread using the sewing data conversion program and converting the calculated ratio into a sewing data in a linear shape and a zigzag shape.

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.

Disclosed are modularized garment manufacturing method and system for small quantity batch production of garments. Basic components constituting an ordered garment are generated by analyzing shape graphic data of the ordered garment. For each basic component, basic patterns are generated for each dimension of the ordered garment. The basic patterns are compared with reference garment patterns stored in a garment pattern database to determine a pattern category of each basic pattern. Based on the pattern category of the basic patterns and information on garment production lines currently in operation, subdivided work modules are determined for each basic pattern. A configuration of modular sewing process lines, which include module processing lines for manufacturing the working modules and component-joining process lines for completing production of the ordered garment by joining the basic pattern products produced in each module processing line, is designed based on operation information of a garment production line.

A software activation system includes a sewing machine and at least one server connected via a network. The sewing machine acquires an authentication code corresponding to an activation target software that is at least one of a program and data not activated on the sewing machine, and transmits, to an authentication server included in the at least one server, an authentication request including the acquired authentication code. The server acquires an authentication key on the basis of the authentication request, when the authentication request is received by the first receiver; and transmits the acquired authentication key to the sewing machine. The sewing machine also receives the authentication key from the authentication server, determines whether the received authentication key satisfies a predetermined authentication condition, and activates the activation target software on the sewing machine when it is determined that the authentication key satisfies the predetermined condition.

A sewing machine includes a sewing portion, a movement portion, a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data indicating positions of a plurality of needle drop points to sew a pattern, acquiring a position of a sewing start point of the pattern, performing first correction, performing second correction that uses the acquired position of the sewing start point as a base point, and corrects the pattern data, by changing, by an acquired change amount, the positions of the plurality of needle drop points represented by the pattern data corrected by the first correction, and controlling the sewing portion and the movement portion and sewing the pattern on the sewing object, in accordance with the pattern data corrected by the second correction.

Provided is a sewing machine that enables a user to grasp the position of an interested point that is present inside and outside a stitchwork pattern without relying upon the user's imagination. This sewing machine includes an operation screen that displays, in a screen region, a frame image and a stitchwork image, and receives a user input of an interested point within a stitchwork frame displayed in the screen region. Moreover, the stitchwork frame is horizontally moved until a needle points out a point within the stitchwork frame and corresponding to the interested point input using the operation screen.

A sewing machine includes a feed amount setting part and a feed amount adjustment part. In the feed amount setting part, a forward feed amount for one stitch of forward stitching is set. In the feed amount adjustment part, the forward feed amount which is set by the feed amount setting part is compared with the maximum backward feed amount for one stitch of reverse stitching which is determined by a feed mechanism. Then, in the feed amount adjustment part, when the forward feed amount is larger than the maximum backward feed amount, the total amount of backward feed amounts for plural stitches of backward stitching is adjusted so as to coincide with the total amount of the forward feed amounts for one stitch or more of forward stitching.

A sewing machine acquires a selected pattern that is selected from among a plurality of embroidery patterns. The sewing machine displays a pattern image representing the selected pattern. The sewing machine identifies a specified position indicated by the instruction. The sewing machine determines, when the selected pattern is acquired a plurality of times, whether one of a plurality of the pattern images is displayed at the identified specified position. When it is determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which the pattern image is displayed at the specified position as the editing target. When it is not determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which a mask region encompassing the selected pattern is set at the specified position as the editing target.

A terminal has: a sewing information file preparation unit for preparing a sewing information file which includes a sewing information related to a particular sewing data selected from a plurality of sewing data stored in a predetermined folder of a storage unit; and a storage processing unit for storing the prepared sewing information file in another folder of the storage unit. A sewing machine includes: a reading folder determination unit for determining a folder to which the sewing information file to be sewn is read from the storage unit based on the current operation mode; and a sewing data acquisition unit for referring to the sewing information included in the sewing information file from the determined folder and acquiring the particular sewing data.

A computer-readable medium stores instructions for a processor in a sewing data generation device. When the instructions are executed, the processor acquires pattern data of embroidery pattern including partial patterns using different thread. If first common data indicating the same thread is included in first data of a first embroidery pattern and second data of a second embroidery pattern, the processor sets a sewing order in the first data, while causing the partial pattern using the thread of the first common data to be the partial pattern that is last in the sewing order in the first embroidery pattern, and sets a sewing order in the second data, while causing the partial pattern using the thread of the first common data to be the partial pattern that is first in the sewing order in the second embroidery pattern that is the embroidery pattern subsequently to the first embroidery pattern.
