Description

[Detailed Description of the Invention] (Technical Field) The present invention provides a pattern indexing method for use in an electronic sewing machine, particularly an electronic sewing machine equipped with a built-in electronic storage device in which pattern data for a large number of sewing patterns is stored. This relates to an indexing device.

(Prior art) Due to recent improvements in semiconductor integration technology, the electronic storage device built into the above-mentioned electronic sewing machine can now be configured in an extremely small size even with a large storage capacity. It is now possible to store a much larger amount of pattern data.

By the way, in order to select a pattern on the above-mentioned electronic sewing machine, there are generally pattern selection keys that are operated individually corresponding to each pattern;
A display section for the selected pattern is required, and as electronic sewing machines begin to store a large amount of pattern data, the number of these components will inevitably increase.

However, there is a limit to the space available in the head of a sewing machine to install a pattern selection device equipped with these components, and if too many patterns are displayed, the various components necessary for pattern selection become extremely small. This makes selection difficult and also makes the design unsightly.

On the other hand, when considering the degree of necessity for each pattern, some patterns are used frequently, while others are used less frequently, such as those used only for special purposes or occasionally depending on one's preference.

(Purpose of the invention) This invention was devised taking into consideration the frequency of use of the above-mentioned patterns, and a pattern index board that displays each pattern number and each design corresponding to the less frequently used patterns is opened and closed on the pattern panel. The invention aims to improve the operability of the pattern index and the design of the sewing machine head.

(Structure of the idea) Embodiments of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is a pattern panel attached to the sewing machine frame (not shown), Po to P are display parts for frequently used patterns (hereinafter referred to as 1st pattern group), and MM is 1 As a group, there are three rows of these, making a total of three throats.

Ko, 9 is the pattern display part P. - Pattern selection key arranged corresponding to P9, No-N.

is a 7-segment type number display device in which 2 and 3 display the pattern number displayed corresponding to the key, and 2 and 3 display the pattern numbers of the less frequently used patterns (hereinafter referred to as 1st and 2nd pattern group), which will be described later. be.

Reference numeral 4 designates a pattern switching key for switching the pattern selection keys 9 to 9 to select the first pattern group or the second pattern group.

5 is a pattern index board consisting of a left door 6 and a right door 7 disposed on the pattern panel 1 directly below the pattern switching key 4;
As shown, the right end surface of the left door 6 and the left end surface of the right door 7 are hinged to the pattern panel 1 by a pivot 8.

That is, the left door 6 and the right door 7 are hinged to the pivot 8 so that they can be opened and closed to the left and right.

6a and 7a are index tables displayed on the back of the left door 6 and the right door, respectively, and the index tables include the patterns 6b and 7b of the second pattern group, which are the less frequently used patterns, and the numbers of the patterns corresponding thereto. 6c.

7c is displayed.

In addition, in FIG. 2A, 9 is an index table in which patterns 9a of the second pattern group and corresponding numbers 9b are displayed on the pattern panel 1 corresponding to the back side of the left door 6, and 10 is similarly a table showing the numbers 9b corresponding to the patterns 9a of the second pattern group.
This is an index table in which patterns 10a of the second pattern group and corresponding numbers 10b are displayed on the pattern panel 1 corresponding to the back side of the figure.

In FIG. 2B, the left door 6 is rotated 180 degrees from the state shown in FIG.

As can be seen in the figure, index tables 6a and 9 are rSATINJ (satin stitch), 1 FANTASY (automatic feed), and 2.
are divided into two groups and displayed.

Figure 2C shows the left-opening state in which the right door 7 has been rotated 180 degrees from the state shown in Figure A and overlapped with the left door 6. In this state, the index tables 7a and 10 are arranged as shown in Figure 4. Become.

As you can see in the figure, the index table is rLETTER8J (alpha head), rONEPOINT (one point), 2
are divided into two groups and displayed.

Next, the selection of the first pattern group and the second pattern group will be explained. The selection of the first pattern group is performed by appropriately pressing the pattern selection keys ≦ - ≦ when the pattern switching key 4 is in the reset state.

To select the second pattern group, first press the pattern changeover key 4 to set it, find the number of the desired pattern from the index table on the pattern index board 5 in the state shown in FIG. 3 or 4, and press the pattern selection key Ko. Ke pattern number N.

-Refer to N9 and press 2 on the corresponding pattern selection key Ko-.
Press twice to select the pattern number N.

The value -N9 is displayed on the pattern number display devices 2 and 3, making the program of the second pattern group executable.

If it is desired to select the first pattern group again, this can be done by pressing the pattern switching key 4 which is in the set state to bring it into the reset state.

Although not directly related to the present invention, 11 is a thread tension dial that adjusts the upper thread tension, 12 is a reverse stitch key that performs reverse stitching while being pressed, 13 is a cancel key that cancels memorization and reversal memory, and 14 is a cancel key. 15 is a reversal memory key that memorizes the selected pattern in reverse order, 16 is a repeat key that memorizes the selected pattern for 10 cycles, and 17 is a no-feed key that lowers the feed dog (not shown). key, 18 is the 2-wood nail key that limits the stitch width to 2-wood nails, 19 is the low speed key that limits the sewing speed, 20 is the stop stitch key that stops the sewing machine in a fixed position, 21 is the stitch width 22 is a feed dial for selecting the stitch feed, and 23 is a width key for periodically changing the stitch width.

(Effect of the invention) As described above, according to the invention, when selecting the second pattern group that is used less frequently, the pattern panel and By reading the desired pattern number from the index table displayed on the left and right doors and operating the pattern switching key and pattern selection key, the program for the second pattern group can be executed. Even if the number is quite large, the pattern panel and left or right door will serve as a pattern index table.
Since the surface area can be increased, it is very easy to see and select patterns.

In addition, the left and right doors can be closed when they are not needed, resulting in a cleaner design.

Furthermore, since the pattern switching key and the number display device are arranged near the index table, it is convenient when selecting the second pattern group.
