DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a sewing machine with an embroidery function, in which an image of an applique shape is input in order to easily install the applique, and the data of the applique sewing is automatically obtained from the input external shape data. Generate
It is about the sewing machine with embroidery function to which the applique can be attached.

[0002]

2. Description of the Related Art At present, in the case of sewing machines with an embroidery function, installation and sewing of generally sold appliqués and the like have been performed in a manner similar to manual work using straight stitching and zigzag stitching. However, this work relied on the experience of the workers, so the finish was not clean and difficult.

[0003]

When sewing or mounting appliques or the like using a sewing machine with an embroidery function, the shape of each applique differs, so that a pattern cannot be stored in advance, and the operator cannot fit the outer shape. It was necessary to operate to form the seam along with it, and it was difficult to finish it neatly. Also, it was not possible to automatically and beautifully sew appliques and the like sold on the market.

[0004]

The inventor of the present invention has conducted intensive studies to solve the above-mentioned problems, and as a result, the invention was read by an image input device and an original pattern image input device in a sewing machine with an embroidery function. Image data storage means for storing and holding data, applique mounting data generating means for mounting an applique or the like from the image data, and mounting data storage means for storing and holding the generated data, whereby the applique is automatically embroidered by the sewing machine. The above-mentioned problem has been solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a sewing machine with an embroidery function according to the present invention, which refers to an embroidery sewing machine capable of performing only embroidery sewing and a composite sewing machine capable of performing ordinary sewing and embroidery sewing.

[0007] The sewing machine 1 with an embroidery function incorporates a computer program in advance and is configured to perform various embroidery operations by a control device including a central processing unit (CPU). Sewing machine 1 with embroidery function
The front panel 10 has a start / stop key 6 for starting and stopping the sewing machine, a liquid crystal display device 7, a pattern selection unit 8, an operation key 9, and a card reader for reading data from and writing data to the RAM card 5. / A writer section 11 is provided.

The operation keys 9 include an image scanner input mode selection key 14a for selecting an image scanner input mode, a conversion key 9b for instructing to convert applique data read from an image reading device into sewing data, Etc. are included.

The liquid crystal display device 7 displays a message for instructing a sewing operator on the operation procedure of the sewing machine, applique data read from the image reading device, and the like.

Reference numeral 2 denotes an embroidery frame for holding an embroidery cloth. The embroidery frame 2 is fixed so as to be freely mounted on a carriage driven in the X-axis and Y-axis directions by XY driving means (not shown). You.

Reference numeral 12 denotes an image scanner as an example of an image reading device, and a reading start button 13 is provided on a side surface thereof. The image scanner 12 is electrically and mechanically connected to the sewing machine 1 with an embroidery function by a dedicated cable 14 and a plug (not shown).

Reference numeral 15 denotes an applique or paper on which the outline of the applique is drawn. This pattern is read by the image scanner 12.

FIG. 2 is a block diagram according to the present invention.
The sewing of the applique is performed by a sewing machine motor 18 for moving the needle of the stitch forming means up and down and a embroidery machine through a driving means by receiving the sewing data from the data memory in the applique data storage means by the control means which is the central processing unit 19. It is formed by controlling and driving the driving pulse motor in the frame driving means 17.

Next, a method of sewing an applique will be described with reference to FIG. A commercially available applique is read using an image reading device such as the image scanner 12. Read the applique as it is with the image scanner or read the outline of the applique on paper with a writing implement using the image scanner. This is stored in the image reading data storage means 20 as image reading data (outline data).

Based on the read data, applique data generation means 21 generates applique sewing data. At this time, select the sewing pattern (linear sewing, zigzag sewing, etc.) and determine the sewing. For example, in straight stitching, stitch data is generated several millimeters (can be specified arbitrarily) inside the outline data.

An applique mounting position display device using an optical display means is provided at an appropriate position on the sewing machine main body.
The outline sewing position is displayed under the condition where the data, needle position and data are matched. The applique is attached so that it matches the displayed outline, and sewing of the applique mounting sewing is started by the sewing start switch 6. The sewing is started based on the outline data obtained by the image reading device such as the image scanner 12, and the sewing is completed in the same manner as the embroidery pattern sewing.

In this embodiment, the data read by the image scanner is stored in the memory card mounted in the sewing machine main body. However, a dedicated memory having a function of storing the data in a memory card separate from the sewing machine main body is provided. There is also a method of using a memory storage device, storing it on a memory card, and attaching this memory card to the memory card reader of the sewing machine.

[0018]

As is evident from the above description, according to the present invention, anyone can easily sew an applique without mistake, and a beautiful finish can be obtained, and the sewing machine user can easily work. This has the effect of increasing productivity.
