Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a display device and a sewing machine.
[0002]
[Prior art]
In recent years, embroidery devices that perform embroidery mechanically and those that have a function of causing a sewing machine to perform embroidery stitching have become widespread.
[0003]
[Problems to be solved by the invention]
When performing embroidery mechanically, the embroidery range is limited to the mechanical movable range of the embroidery device. That is, it is impossible to perform embroidery in a range that is greater than or equal to the movable range of the mechanism that moves the cloth that is the embroidery object. Therefore, when performing a large embroidery that exceeds the embroidery range, it is necessary to change the position of the cloth and repeat the embroidery several times.
Such a limit is particularly problematic in an embroidery machine. In other words, the movable range is limited to a very narrow range due to the rising portion of the sewing machine, so that the embroidery frame supporting the cloth is small and the size of the embroidery is limited to a small one. In order to solve this problem, a large embroidery is sewn by changing the cloth to the embroidery frame. However, in order to accurately match the embroidery seam, a template with a finished embroidery pattern is required. In addition, it is necessary to use a special device for alignment.
The present invention aims to remedy the drawbacks of the prior art described above.
[0004]
[Means for Solving the Problems]
To achieve the above object, the present invention provides an embroidery comprising a mechanism for holding an object to be embroidered, and a sewing mechanism for executing embroidery sewing by moving the holding mechanism relative to the X and Y directions. A display device for performing display related to embroidery information for a sewing device, comprising: data for displaying an embroidered pattern; and a reference mark for specifying the relationship between the position of the pattern and the holding mechanism and the angle. Data for display, means for storing a plurality of pattern data, means for selecting an arbitrary pattern among the plurality of pattern data, and a position between the selected patterns Means for setting; means for calculating a distance in the X direction and the Y direction between the positions specified by the reference mark of the selected pattern; and the plurality of selected patterns Display distance and Characterized by comprising a means for.
When embroidery sewing is performed on a plurality of patterns while shifting the position of the cloth to be embroidered with the mechanism that holds the embroidery frame or the like, if the distances in the X and Y directions between the selected patterns are displayed, the user can By shifting the attachment position of the embroidery frame and the cloth based on the distance, it becomes possible to perform embroidery accurately and continuously. Moreover, the template etc. which were conventionally required are not required.
Any reference mark can be used as long as the position and angle can be specified. Typically, a cross mark is used, and the cross point is set as a reference point for specifying the position, and an arrow is provided at one end of the line. Etc. are preferably used to display the reference angle. It is desirable that the position and angle of the reference mark be constant with respect to the mechanism to be held at all times. In addition to being constant between patterns, the reference mark is also used when performing operations such as enlarging, reducing, rotating, and turning over as described later. It is desirable not to change.
It is also possible to display the embroidery possible range according to the movable range of the holding mechanism. Since the holding mechanism includes an embroidery frame for holding a normal cloth, and normal embroidery sewing is performed within the frame, it is desirable to display the frame together with a pattern.
In many cases, a function of performing embroidery stitching by enlarging, reducing, rotating, turning over, etc. a pattern is provided, and in order to cope with such a change, at least one of the above processes is performed on the pattern. A means for adding to the display data may be further provided. In the case of performing rotation or the like, it is possible to continuously perform embroidery while rotating the embroidery frame by calculating and displaying the difference between the patterns of the angle specified by the reference mark.
Means for generating data representing the actual content displayed on the display means, and means for printing the actual content based on the data represented by the actual size; By printing in actual size, it becomes possible to perform the same function as a conventional template.
The display device described above may be a single device, or may be incorporated into an embroidery device or a sewing machine that can be embroidered.
In addition, in this application, a pattern is used in the meaning which shows everything which becomes the object of embroidery, such as a pattern, a character, a number, a symbol.
