  According to a fourth aspect of the present invention, the amplitude amount and the feed amount input to the input device are obtained from a needle drop position input to a computer.

  In the first aspect of the invention, since the operator creates the sewing pattern only from the amplitude amount and the feed amount, the number of data input switches may be two. Therefore, it is easy for beginners to understand the operation, and there is no need to search for a switch to be input, thereby improving operability.

  In the invention according to claim 2, since the amplitude amount and the feed amount input from the input device are displayed on the display device, the operator inputs while confirming the amplitude amount and the feed amount previously input.

In addition, since the same symbol or the same code | symbol in a figure shows the component which is the same or corresponds, the detailed description is abbreviate | omitted and it mainly demonstrates only a different point.

  A first embodiment of the present invention will be described.

  FIG. 1 is an external view of the sewing machine of the present invention. A needle bar connected to a drive unit (not shown) is supported on the sewing machine main body 1 (sewing machine) so as to move left and right and move up and down, and a needle is detachably fixed to the tip of the needle bar. A needle plate 4 is formed below the needle of the sewing machine body 1, and a needle hole into which the needle enters and a feed dog groove in which a feed dog driven in the front-rear direction orthogonal to the lateral movement of the needle bar is provided. . The main body sewing machine 1 is provided with an input display device 7 provided with an input device for inputting an amplitude amount and a feed amount of a needle when an operator creates a sewing pattern and a display device for displaying the input amplitude amount and the feed amount. I have. A workpiece such as a cloth is selected by the pattern selection dial 6 based on the sewing pattern created by the operator by the vertical and horizontal movements of the needle connected to the drive unit of the sewing machine body 1 and the forward and backward movement of the feed dog. A sewing pattern is sewn with a sewing pattern.

  FIG. 2 is a diagram showing the input display device 7. The operator inputs a sewing pattern to be sewn to the sewing material made of cloth or the like from the input device 14 of the input display device 7 provided in the sewing machine body 1. The input device 14 includes an amplitude amount input switch (amplitude data input means) 16 for inputting the amplitude amount of the needle drop position constituting the sewing pattern, and a feed amount input switch (feed data input means) 19 for inputting the feed amount. . The amplitude amount input switch 16 includes an amplitude amount advance switch 16a and an amplitude amount return switch 16b, and the feed amount input switch 19 includes a feed amount advance switch 19a and a feed amount return switch 19b. The amplitude amount input from the amplitude amount input switch 16 is displayed on the amplitude amount display unit 17 as an amplitude amount display 18. Similarly, the coordinate of the feed amount input from the feed amount input switch 19 is displayed on the feed amount display unit 22 as a feed amount display 23. In addition, a clear switch 20 is provided for correcting an erroneous input and an enter switch 21 for registering the input data. The amplitude amount display 18 and the feed amount display 23 are displayed by blinking the amplitude amount or the feed amount, which is input from the amplitude amount input switch 16 and the feed amount input switch 19, and is made up of numerals or symbols. When you press, it stops flashing and lights continuously. Next, when coordinates are input from the amplitude amount input switch 16 and the feed amount input switch 19, the previous display disappears and the next input coordinates are displayed blinking as an amplitude amount display 18 and a feed amount display 23. .

  FIG. 3 is a diagram showing a quick reference table 51. The quick reference table 51 provided as an accessory to the sewing machine main body 1 or as an optional member is a card made of paper or a resin plate. In the quick reference table 51, a sewing pattern 15 is created in which the needle drop positions P31 to P37 are determined and sewed on a sewing product. On one or both sides of the quick reference table 51, the coordinates 0 to 9 and A to Z of the amplitude 12 are displayed in the horizontal direction, and the coordinates 0 to 9 and the coordinates A to Z of the feed amount 13 and the scale are displayed in the vertical direction. Yes.

A sewing pattern that the operator desires to sew on the sewing product with the sewing machine body 1 is studied and created.

The needle drop positions P31 to P37 are determined in the quick reference table 51, and the sewing pattern 15 to be sewn on the workpiece is created. Since the quick reference table 51 is in a card format, if a number or a name is given to the quick reference table 51 and stored, it is convenient because data of sewing patterns and needle drop positions (coordinates) created in the past can be read.

  Hereinafter, the operation of the input display device 7 of FIG. 2 provided in the sewing machine body 1 will be described using the quick reference table 51 of FIG. 3 created by the operator.

  The coordinates of the amplitude amount 12 and the coordinates of the feed amount 13 of each needle drop position P31 to P37 of the sewing pattern 15 created in the quick reference table 51 are read.

That is, the coordinate of the amplitude amount 12 of the needle drop position P31 is “6”, and the coordinate of the feed amount 13 is “1”. Similarly, the coordinate of the amplitude amount 12 of the needle drop position P32 is “B”, and the coordinate of the feed amount 13 is “2”. Thereafter, the coordinates of the needle drop positions P33 to P37 are similarly read.

  Next, the operator inputs the coordinates of the amplitude amount 12 and the feed amount 13 of the needle drop positions P31 to P37 plotted in the quick reference table 51 from the input device 14 of FIG.

  Since the coordinate of the amplitude amount 12 of the needle drop position P31 is “6”, when “6” is displayed on the amplitude amount display portion 17 by operating the amplitude advance switch 16a or the amplitude return switch 16b of FIG. 21 is pressed to register the amplitude amount of the needle drop position P1. Next, since the coordinate of the feed amount 13 at the needle drop position P31 is “1”, the operator appropriately operates the feed advance switch 19a and the feed return switch 19b, and “1” is displayed on the feed amount display section 22. Then, the enter switch 22 is pressed to register the feed amount at the needle drop position P1 (state shown in FIG. 2). If the coordinates of the amplitude amount 12 and the coordinate of the feed amount 13 are input by mistake and registered by pressing the enter switch 21, the input state is restored when the clear key 20 is pressed. And the enter switch 22 may be pressed. Thereafter, when the input of the coordinates of the amplitude amount 12 and the feed amount 13 from the needle drop position P32 to P37 is completed in the same manner, the enter switch 22 is further pressed once (the final amplitude value 12 or the feed amount 13 at the needle drop position P37). When the input is finished, the enter switch 22 is continuously pressed twice), and needle drop position data (coordinates of the amplitude amount 12 and the feed amount 13) from the needle drop positions P31 to P37 are incorporated in the sewing machine body 1. It is stored in a storage device such as a flash memory.

  From the needle drop position data from the needle drop positions P31 to P37 stored in the storage device, the central processing unit performs calculation processing to create pattern sewing data. Based on this pattern sewing data, the lateral movement (amplitude direction) of the needle of the sewing machine body 1, the speed of vertical movement, the movement of the feed dog, and the like are controlled.

  As described above, after inputting and registering the amplitude amount 12 and the feed amount 13 of each needle drop position of the sewing pattern 15 as coordinates, a sewing pattern such as straight stitching or zigzag sewing is sewn on the sewing machine body 1. If the sewing is selected at 8 and sewing is started, the sewing pattern 15 constituted by the input needle drop positions P31 to P37 is repeatedly sewn on the sewing product until the sewing is stopped.

  In the first embodiment, the amplitude amount 12 and the feed amount 13 are input by one digit. However, the number of digits of the amplitude amount display unit 17 and the feed amount display unit 22 is appropriately increased, and the amplitude amount 12 and the feed amount 13 are changed. The maximum width can be increased.

The input display device 31 according to the second embodiment is provided with an input device 32 for inputting the amplitude amount and the feed amount of the needle drop position constituting the sewing pattern. When the advance switch 38 is pressed, the number changes from 1 to 2 and 3 and the alphabet changes from A to B and C and is displayed on the display unit 33 formed of a liquid crystal display panel. When the return switch 39 is pressed, the number changes from 9 to 8, 7 and the alphabet changes from Z to Y, X and is displayed on the display unit 33. Registration is performed by proceeding to the input display position 40 of the display unit 33 and properly operating the switch 38 or the return switch 39 to display a desired number or sign and pressing the enter switch 34 once. If the input of the sewing pattern consisting of a plurality of needle entry position data is completed and then the enter switch 34 is pressed twice, the registration of the sewing pattern is completed. The scroll switch 41 can search for input data that is displayed or not displayed on the display unit 33 by moving it to the left or right, and uses a clear key to correct the searched numbers and signs. 64, A6, 67, 89, and 6B displayed on the display unit 33 indicate a state in which the needle entry position data of P31 to P37 of the sewing pattern 15 in FIG.

  Details of the case where the amplitude amount 12 and the feed amount 13 of the needle drop positions P31 to P37 of the sewing pattern 15 separately created in the quick reference table 51 of FIG. 3 are input to the input device 32 will be described below.

Since the coordinate of the amplitude amount 12 of the needle drop position P31 of the sewing pattern 15 of FIG. 3 is “6”, the advance switch 38 and the return switch 39 are appropriately operated to move to the latest input display position 40 of the display unit 33. When “6” is displayed, the number “6” blinks. The display of “6” when the enter switch 34 is pressed is continuously lit and moves one character to the left. (The latest input display position 40 for one character blinks the backlight, and there is no display of numbers or symbols.)
Next, the coordinates of the feed amount 13 at the needle drop position P31 are advanced in the same manner as described above, the switch 38 and the return switch 39 are appropriately operated, “1” is displayed at the latest input display position 40, and the enter switch 34 is pressed. Then, the input of “1” is registered, and the display of “1” moves to the left from the display position 40 being input, and “,” (comma) is automatically given to the right side of 1. (A comma indicates that registration of one needle drop position composed of an amplitude amount 12 and a feed amount 13 has been completed. The latest input display position 40 for one character blinks in the backlight, and a number or symbol is displayed. There is no indication.)
Similarly, the coordinates of the amplitude amount 12 and the coordinates of the feed amount 12 from the needle drop positions P32 to P37 are input, and finally the enter switch 34 is pressed twice. When the above input is completed, the display unit 33 displays the coordinates of the amplitude amount 12 and the coordinates of the feed amount 13 from the needle drop positions P33 to P37.

After the input is completed, if you want to check the coordinates of the amplitude amount 12 of P32 and the coordinates of the feed amount 13 that are not displayed on the display unit 33, press the left arrow part of the scroll switch 41 to display the coordinates of the amplitude amount 12 Alternatively, the coordinates of the feed amount 13 sequentially move from the left side to the right. When correcting the coordinate of the amplitude amount 12 and the coordinate of the feed amount 13 displayed on the display unit 33, the coordinate of the amplitude amount 12 or the feed amount 13 to be corrected displayed on the display unit 33 is operated by operating the scroll switch 41. Fit to the coordinates of. Since the corrected portion blinks, when the clear switch 35 is pressed, the blinking coordinates disappear from the display unit 33. Therefore, when a new coordinate is input by the input device 32 and the enter switch 34 is pressed twice, the corrected sewing pattern is completed. (By pressing the first enter switch 34, the input coordinates of the amplitude amount 12 or the coordinates of the feed amount 13 are registered, and by pressing the enter switch 34 for the second time, the input of the sewing pattern is completed.)
Further, when the sewing pattern input is completed and registered in the input device 32 of FIG. 4, the central processing unit built in the sewing machine body 1 calculates and stores the pattern sewing data which is created and stored in the storage device. A number may be given to the sewing pattern on the left side of the first needle entry position data on the display unit 33. Taking the sewing pattern 15 as an example, in order to give a number “1” to the sewing pattern, “01-” is given to the left side of the needle entry position data of the sewing pattern, and “01-61, B2, The following needle entry position data is omitted. ”Is displayed. Similarly, “10-61, B2, the following needle entry position data is omitted” is displayed in order to assign the number “10” to the sewing pattern. The operator writes the numbers “1” and “10” in the quick reference table 51 of the sewing pattern corresponding to the numbers “1” and “10”, respectively. When the sewing pattern created in the quick reference table 51 is corrected, the scroll switch 41 of the input display device 31 is operated to change the needle entry position data number (for example, “1”, “10” described above) of the desired sewing pattern. ) Can be sewn on the workpiece with the called needle entry position data. In addition, since the needle drop position data of a new sewing pattern can be created by partially correcting the needle drop position data of the configuration pattern that has already been created and registered, it is not necessary to input all the needle drop position data of the sewing pattern. Thus, the time for inputting the needle entry position data can be shortened.

  FIG. 5 is a diagram showing a sewing product that has been sewn with a sewing pattern. The material of the cloth 51 is a cotton cloth. The needle entry positions P31 to P37 of the sewing pattern 15 are input from the input device 14 of FIG. 2 or the input device 32 of FIG. 4 for registration, and the sewing pattern is selected and sewn with the pattern selection dial 8 of the sewing machine body 1. is there.

The sewn sewing pattern reaches from the needle drop position P31 to P32, P33,... P37, and stops at P31, P32, and P35. The sewing machine body 1 repeatedly sews the sewing pattern 15 that is input and registered according to the sewing time.

  The sewing pattern sewn on the cloth 51 is appropriately switched by the pattern selection dial 8 of the sewing machine body 1, and from the upper part of FIG. 5, sewing is performed with running stitches from P31 to P35, and P37 to P34 is sewn with cross stitches. P34 to P35 are sewn by zigzag stitching.

  The needle drop positions P31 to P37 constituting the sewing pattern 15 of FIG. 3 are input by the input device 14 including the amplitude amount input switch 16 and the feed amount input switch 19, and the sewing pattern selected by the pattern selection dial 8 The interval between the needle drop positions may be large only by sewing the seven needle drop positions from the needle drop positions P31 to P37. It is not possible to obtain a good finish in a sewing pattern composed of a continuous pattern such as holding a sewing thread or embroidery. Therefore, when sewing a sewing pattern such as a cross stitch or a running stitch continuously, the entered needle entry positions P31 to P32 and P32 to P33 are input by the central processing unit built in the sewing machine body 1. By measuring and calculating the interval between each needle drop position, and setting a new eligible needle drop position between each needle drop position and sewing. A good sewing pattern can be sewn. In addition, if an adjustment means is provided to set the interval between each needle drop position including this new needle drop position, it is easy to sew a sewing pattern with a better finish than sewing only at the input needle drop position. I can do it.

  FIG. 6 is a diagram illustrating an input screen of the display device.

  In the third embodiment, a sewing pattern is created using a computer.

  In FIG. 6, sewing pattern creation software created separately is installed in a computer (not shown), and an input screen 63 is displayed on a display screen 62 of a display device 61 connected to the computer. The input section 65 of the input screen 63 displays needle drop positions P61 to P65 that constitute a sewing pattern 64 that is input to the computer by clicking a mouse (not shown) connected to the computer.

  Further, when the conversion 66 portion is clicked by the mouse, the computer calculates from the amplitude amount and the feed amount data at each of the needle drop positions P61 to P65 inputted to the computer by the mouse click, and the input of the sewing machine body 1 is performed. Input data including the amplitude amount and the feed amount at each of the needle drop positions P61 to P65 to be input to the device 14 (FIG. 2) or the input device 32 (FIG. 4) is displayed on the input data display section 67.

If the needle entry position is entered by mistake, clicking the correction 67 with the mouse erases the needle entry position input to the computer, so that it can be corrected to a new needle entry position.

  In this embodiment, the needle is moved relative to the sewing object such as the cloth to be sewn with the sewing pattern by controlling the movement of the needle in the left-right direction and the movement of the feed dog in the direction perpendicular to the left-right direction of the needle. However, the sewing pattern may be sewn on the material to be sewn by moving the holding frame, which holds the sewing object to be sewn on the sewing pattern, relative to the needle. According to this method, the amplitude amount and the advance amount can be easily set large.

  The operator inputs the amplitude and feed amount when creating the sewing pattern, and since the number of switches to be input is small, it is easy to select the switch to be input when inputting the needle entry position. It is easy to understand and easy to operate.

  In addition, since the number of switches is small, the size of the switch button and the display size can be secured without any hindrance to the input operation even in a limited space, improving the visibility and improving the input operability. .

  Further, since the display unit 33 displays a plurality of amplitude amounts and feed amounts input from the input device 32, the operator can input while confirming the previously input amplitude amount and feed amount, and the needle drop position data Input is easy, incorrect input is prevented, and operability is improved.

  By using the quick reference table 51 in which the amplitude amount and the feed amount are displayed on the XY coordinates, various sewing patterns imaged by the operator on the quick reference table 51 can be studied, and a better sewing pattern can be created. Further, by reading the coordinates of each needle drop position plotted in the quick reference table 51 from the XY coordinates, the input amplitude amount and feed amount can be easily obtained from the quick reference table 51, and erroneous input is prevented and operability is improved. To do.

  Since the needle entry position is input to the computer while viewing the input screen 63 of the computer, the operator can easily imagine a sewing pattern from the input needle entry position and can create a better sewing pattern. The amplitude and feed amount input to the input device 14 or 32 are calculated by the computer from the needle entry position input to the computer, and the data displayed on the input data display section 67 is input to the input device 14 or 32 as it is. As a result, erroneous input is prevented and operability is improved.

  In recent years, there are seven general household products that anyone can use and obtain, easy to understand how to use, and information (necessary for operation, etc.) can be easily communicated to users (ease of understanding). The idea of universal design is used to make products in consideration of the principle.

  The present invention is inexpensive and easy to use for anyone. Easy to understand how to use because there are few switches to input. Because there are few characters and switches to display or input and it is not too small, information can be easily communicated to the user. It can be said that it is a product that takes into account the universal design.
