Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Field of Industrial Application) The present invention relates to a sewing machine that is capable of forming a predetermined picture pattern on a processed cloth.

(Prior Art) In recent years, for example, home sewing machines have been provided that are capable of forming a predetermined picture pattern on work cloth based on pattern data corresponding to the picture pattern. This device is equipped with a large amount of pattern data stored in memory in advance, and a control device such as a microcomputer reads out the predetermined pattern data, and based on this, a pattern forming mechanism consisting of a sewing needle drive mechanism, cloth feeding mechanism, etc. It is designed to form a predetermined picture pattern on the work cloth by controlling the

In conventional sewing machines, all the marks corresponding to each pattern are printed and displayed along with the numbers on the mark marking area provided on the front of the sewing machine body, and the user looks at the marks, selects the number of the desired pattern, and then selects the number. The desired pattern was selected by inputting the number by operating a selection switch on the operating section. However, when all the marks are written in the mark writing section like this, the area where the marks can be written is limited, so when there are many types of patterns, each mark becomes small and difficult to see, or all the marks There was a problem where it was not possible to write the full text.

In recent years, in order to fully meet the diverse demands of users, the number of patterns that can be formed has tended to increase; for example, 30
Sewing machines equipped with 0 to 400 pattern data have also been provided. This machine is equipped with a card holder on the front of the sewing machine body, in place of the above-mentioned mark writing section, in which a card can be set in a replaceable manner, and a display section consisting of an LCD for displaying patterns and messages to the user. I have to.

A plurality of types of cards are prepared, such as one-point pattern cards, decorative pattern cards, etc., and each card has a mark such as a picture pattern or a letter pattern written thereon along with a number. When the user selects a desired picture pattern, the user sets the card with the picture pattern mark written on it into the card holder, and inputs the number corresponding to the picture pattern mark using the numeric keypad on the operation part. It is now possible to enter the At this time, the control device of the sewing machine automatically reads which type of card is set, reads out the display data of the picture pattern corresponding to the input number from the memory, and displays it on the display section. In this state, when the user operates the start key, a picture pattern forming operation is executed based on the pattern data corresponding to the picture pattern displayed on the display section.

(Problem to be solved by the invention) However, with the conventional card system as described above, multiple cards must be prepared in order to show the marks for all patterns to the user, resulting in high costs. There was a problem.

In particular, in the case of picture patterns, unlike text patterns, etc., the number of marks that can be written on one card cannot be increased so much in order to indicate a mark large enough to be easily seen by the user. This results in an increase in the number of cards, resulting in higher costs.

The present invention has been made in view of the above circumstances, and its purpose is to enable the formation of many types of picture patterns, to reduce the space required for writing the picture pattern marks, and to reduce costs. The purpose of the present invention is to provide a sewing machine that can also suppress the rise.

[Structure of the Invention (Means for Solving the Problems)] The sewing machine of the present invention includes a storage means that stores pattern data corresponding to a plurality of patterns, and a storage means that stores pattern data corresponding to a plurality of patterns, and a storage device that stores pattern data corresponding to a plurality of patterns. A group representative mark representing a group of pictures belonging to a group, a group selection switch provided on the operation unit corresponding to this group representative mark, a display changeover switch provided on the operation unit, and this display changeover switch. a display control means for sequentially displaying patterns belonging to a specific group selected by a group selection switch on a display section each time the group selection switch is operated; a selection switch for selecting a pattern displayed on the display section; The present invention is characterized by a configuration including a control means for controlling a pattern forming mechanism to execute a pattern forming operation based on pattern data corresponding to a pattern selected by a switch.

(Operation) According to the above means, marks of all picture pattern groups are not displayed on the operation unit, but a group representative mark representing a picture pattern group belonging to a specific group is displayed. Therefore, the space for writing the picture pattern mark can be kept small.

When the user selects a pattern, the user operates the group selection switch corresponding to the group representative mark representing the specific group to which the desired pattern belongs.
Thereafter, when the display changeover switch is operated, the pictures belonging to that specific group are sequentially displayed on the display section. Therefore, the user can search for a desired picture pattern by looking at the display section, and can select the desired picture pattern by using the selection switch.

Thereafter, the control means controls the pattern forming mechanism based on the pattern data corresponding to the selected pattern to execute the pattern forming operation, thereby forming the pattern desired by the user on the work cloth. Ru.

(Example) An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows the entire sewing machine body 1. The sewing machine body 1 is roughly divided into a bed part 2 whose upper surface is a sewing workbench 2a, and an arm part 3 extending upward and left from its right end. It consists of

Further, on the front side of the sewing machine body 1, an operation section 4, which will be described later, is provided.
is provided. A needle bar 6 equipped with a sewing needle 5 is provided at the tip of the arm portion 3 so as to be able to move up and down and swing from side to side.
A throat plate 7 is provided correspondingly to the needle plate 7, and cloth feed teeth (not shown) are provided on this throat plate 7 portion for feeding the work cloth in the front and rear and left and right directions.
is provided. Although not shown, a motor, a transmission mechanism, etc. for driving the needle bar 6, cloth feed teeth, etc. are provided inside the sewing machine main body 1, and the pattern forming mechanism 8 according to the present invention is operated by these. It is configured. Further, this pattern forming mechanism 8 is controlled by a control device W9.

As shown in FIG. 2, the control device 9 includes CPU10. It is composed of a memory 11 and the like. The memory 11 stores various control programs, as well as a plurality of types of practical sewing data, each character pattern data corresponding to character patterns such as alphabet kana, each picture pattern data corresponding to a plurality of picture patterns, etc. Data for sewing, display data to be described later, etc. are stored in advance. The control device 9 controls each of the mechanisms described above based on the user's operation of a switch, thereby performing various sewing operations. In this case, when the user selects a desired picture pattern as described later, the control device 9 selects a desired picture pattern based on the pattern data stored in the memory 11 and corresponding to the picture pattern.
The pattern forming mechanism 8 is controlled to perform an operation of forming the picture pattern on the work cloth. Therefore, the memory 11 functions as a storage means according to the present invention, and the control device 9 functions as a control means according to the present invention.

Now, as shown in FIG.
2 is provided. This group representative mark section 1
2, the plurality of picture pattern groups are classified into several specific groups, and marks 12a of picture patterns representing each of these groups are shown together with numbers. In this case, all the picture patterns are classified into 12 similar groups, such as a "dog" group, a "boy" group, and a "girl" group. Therefore, for example, the "dog" group includes "dog seen from the side" and "dog running".

A plurality of picture patterns such as "a sitting dog" are included, and among them, the mark 12a of "a dog seen from the front" is shown together with the number "1" as a representative.

The operation section 4 is provided with a group selection switch 13 located below the group representative mark writing section 12. This is for selecting one of the 12 groups, and is made up of, for example, a numeric keypad. Furthermore, this group selection switch 13
A display changeover switch 14 is provided at the bottom of the screen.

Further, a start switch 15 is provided near the tip of the arm portion 3. As shown in FIG. 2, signals from each of these switches are input to the control device 9.

In addition, a display section 16 consisting of an LCD is provided on the front side of the arm section 3.
is provided. This display section 16 is for displaying patterns and messages to the user in the form of images, and as shown in FIG. It is now possible to do so. As will be described in detail later, when the group selection switch 13 is operated, one picture pattern from the group is displayed on the display section 16, and in this state, the display changeover switch 14 is further operated. Each time a pressing operation is performed, the picture patterns belonging to that group are sequentially switched and displayed on the display section 16. Therefore, the control device 9 also functions as display control means according to the present invention. Then, with the picture pattern displayed on the display section 16 in this way, the start switch 1
5 starts a picture pattern forming operation based on pattern data corresponding to the picture pattern displayed on the display section 16. Therefore, in this case, the start switch 15 also functions as a selection switch according to the present invention for selecting a picture pattern.

Next, in the sewing machine configured as described above, the operating procedure when the user wants to form a predetermined picture pattern on the workpiece cloth will be explained with reference to FIG.

First, the user looks at the group representative mark writing section 12, selects a specific group to which the desired picture pattern belongs, and operates the group selection switch 13.

For example, if you want to select the "Elephant" group, the number "4" is written together with the "Elephant" group representative mark 12a.
Operate 3 to input.

Then, the CPU 10 reads out the first display data of the display data belonging to the "elephant" group from the memory 11, and displays a picture pattern of "an elephant seen from the front", for example, as shown in FIG. 3(a). It will be displayed in section 16. Here, when the user selects the displayed picture pattern, when the user operates the start switch 15, the control device 9
controls the pattern forming mechanism 8 based on the pattern data corresponding to the picture pattern, and a picture pattern of "an elephant seen from the front" is formed on the work cloth.

On the other hand, if the picture pattern displayed on the display section 16 is not the one desired by the user, the user operates the display changeover switch 14 this time. Then, CPUl0 is memory 1
1 to the second display data of the display data belonging to the elephant J group, and as shown in FIG. 3(b),
The display on the display unit 16 is now switched to "an elephant facing right." Then, when the display changeover switch 14 is operated again, the display on the display section 16 changes to "elephant facing left" (see Fig. 3(c)), and when the display changeover switch 14 is operated again, the display on the display section 16 is changed to "elephant facing left" (see Fig. 3(c)). The image changes to ``Elephant standing up'' (see Figure 3(d)). In this way, each time the display changeover switch 14 is operated, the patterns belonging to the "elephant" group are sequentially displayed on the display section 16, and the user can display the desired picture pattern on the display section 16. When the start switch 15 is operated, the pattern forming mechanism 8 is controlled based on the pattern data corresponding to the picture pattern, as described above.
The pattern is formed on the processed cloth.

As described above, according to this embodiment, the operation unit 4 does not display marks of all picture pattern groups, but a group representative mark 12a representing a picture pattern group belonging to a specific group.
only shown. Therefore, unlike the conventional method, even if there are many types of patterns, a sufficiently large group representative mark 12a can be written in a small space.

When the user selects a pattern, even if the desired pattern is not listed in the group representative mark writing section 12, the user selects a specific group with the group selection switch 13 and then switches the display changeover switch. 14, it is displayed on the display section 16, so you can look at the display section 16 and search for the desired picture pattern and select it, without having to prepare multiple cards as in the conventional case. I can do it.

Therefore, even if it is possible to form many types of picture patterns, the space for writing the picture pattern marks can be kept small, and an increase in cost can also be suppressed.

In the above embodiment, all the group representative marks 12a are shown in the group representative mark writing section 12.
For example, by preparing and replacing cards with a plurality of group representative marks 12a written on them, it is possible to increase the number of types of patterns. It will be written on a small number of cards, and the intended purpose can be achieved. Further, in the above embodiment, the start switch 15 is also used as a selection switch, but a dedicated selection switch for selecting the picture pattern displayed on the display unit may be provided separately from the start switch.

In addition, various changes can be made to the present invention without departing from the spirit thereof.

[Effects of the Invention] As is clear from the above explanation, the sewing machine of the present invention makes it possible to form a wide variety of picture patterns.
This has excellent effects in that the space for writing the picture pattern mark can be kept small and the cost increase can also be suppressed.
