ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to a sewing machine having a display, which is capable of displaying each attaching position of the work cloth holder corresponding to each partial pattern divided from a large-sized entire pattern.
2. Description of Related Art
Conventionally, a sewing machine is known on which a group of partial patterns to be formed into a large-sized embroidery pattern are sewn by changing the attaching position of the embroidery frame, as a work cloth holder, any number of times.
In such a sewing machine, the attaching position of the embroidery frame is predetermined for each partial pattern. An embroidery pattern whose size is larger than that of the moving range of the embroidery frame can be made by sewing partial patterns after changing the attaching position of the embroidery frame to the position appropriate to each partial pattern.
Even in a sewing machine having a fixed embroidery frame, it is possible to sew partial patterns to form an embroidery pattern whose size is larger than that of the interior of the embroidery frame, while changing the position of the work cloth relative to the embroidery frame any number of times.
However, in the sewing machine on which the attaching position of the embroidery frame can be changed, and when the position is changed, the positional relationship between a partial pattern and its corresponding position of the embroidery frame is indicated only in the instruction manual or other instruction source.
Therefore, every time a partial pattern is sewn, a user has to read the instruction manual or other instruction source to change the attaching position of the embroidery frame or the work cloth. This is a very inconvenient and time-consuming job.
SUMMARY OF THE INVENTION
The invention provides a sewing machine on which a large-sized pattern can be sewn by sewing a plurality of partial patterns while shifting the attaching position of the work cloth holder relative to a moving device or the attaching position of the work cloth relative to the work cloth holder, so that a user can check the relationship between the attaching position of the work cloth holder or the work cloth and each partial pattern more easily.
In this regard, a sewing machine of the embodiment of the invention may include a display, a work cloth holder that holds a work cloth to be sewn, a moving device that moves the work cloth holder attached thereto, a relative attaching position of the work cloth holder to the moving device being changeable, a data reading device that reads sewing data of partial patterns divided from an entire pattern and attaching position data representing a predetermined attaching position of the work cloth holder to the moving device corresponding to each partial pattern, and a display controller that displays attaching position information representing each attaching position corresponding to each partial pattern based on the attaching position data read by the data reading device, on the display.
According to the sewing machine structured as described above, the data reading device reads sewing data of partial patterns divided from an entire pattern and attaching position data representing a predetermined attaching position of the work cloth holder to the moving device corresponding to each partial pattern, then the display controller displays attaching position information representing each attaching position corresponding to each partial pattern based on the attaching position data read by the data reading device, on the display.
Therefore, in the above sewing machine, when a plurality of partial patterns are sewn, information about displaying the work cloth holder position relative to the moving device, which is determined for each partial pattern is indicated on the display. A user can check the attaching position of the work cloth holder relative to the moving device by looking at the information on the display.
Accordingly, there is no need to waste time in reading an instruction manual, to check the attaching position of the work cloth holder, each time a partial pattern is sewn. A user can change the attaching position of the work cloth holder correctly from the information on the display, and sew a large-sized embroidery pattern made up of a plurality of partial patterns more easily.
In a preferred embodiment of the invention, the work cloth holder may include a plurality of connecting portions and be attached to the moving device at one of the connecting portions, and the attaching position data may specify one of the connecting portions corresponding to each partial pattern.
In a preferred embodiment of the invention, the data reading device may read image data for displaying partial patterns on the display, and the display controller may further display the image of the partial patterns in a one-to-one correspondence to the attaching position for the partial pattern.
According to the sewing machine, the display controller shows information about each pattern shape and its corresponding attaching position in a one-to-one correspondence with each other, based on the pattern image data and the attaching position data. Therefore, a user can check the shape of each partial pattern with one look at the display. In addition, before a partial pattern whose shape has been checked is sewn, the user can check a position to which the work cloth holder is attached.
In a preferred embodiment of the invention, the display controller may further display an image of the entire pattern on the display.
According to the above sewing machine, the display control device shows the shape of not only a partial pattern, but also the shape of the entire pattern made up of partial patterns, on the display. A user can check the image of the entire pattern when it is finished on the display.
In a preferred aspect of the invention, the display controller may display sewing order information representing a sewing order of the plurality of partial patterns.
According to the above sewing machine, the display controller shows the information about the sewing order of the plurality of partial patterns. A user just sews patterns in accordance with the displayed sewing order, so that the patterns partially overlap each other in an appropriate order, to form the pattern.
In another preferred embodiment of the invention, the sewing machine may include a display, a work cloth holder that holds a work cloth to be sewn, a moving device that moves the work cloth holder attached thereto, a data reading device that reads sewing data of partial patterns divided from an entire pattern and attaching position data representing a predetermined attaching position of the work cloth to the work cloth holder corresponding to each partial pattern, and a display controller that displays attaching position information, representing each attaching position corresponding to each partial pattern based on the attaching position data read by the data reading device, on the display.
Therefore, in the above sewing machine, when a plurality of partial patterns are sewn, information about displaying the work cloth position relative to the work cloth holder, which is determined for each partial pattern, is indicated on the display. A user can check the attaching position of the work cloth relative to the work cloth holder by looking at the information on the display.
Accordingly, there is no need to waste time reading an instruction manual, to check the attaching position of the work cloth, each time a partial pattern is sewn. A user can change the attaching position of the work cloth correctly from the information on the display, and sew a large-sized pattern made up of a plurality of partial patterns more easily.
