[0003]

By the way, in the above-mentioned household embroidery sewing machine, the sewing of the embroidery pattern is stopped midway,
It was not possible to restart the suspended embroidery pattern sewing after performing embroidery sewing of other patterns and main body sewing.
This is because the data of other patterns to be sewn after the embroidering pattern sewing pause is stored, so that the initially stored data of the embroidery pattern is cleared. For this reason,
There has been a problem that it is not possible to start embroidery sewing of other patterns or main body sewing until the sewing of the embroidery pattern started at the beginning is completed.

An object of the present invention is to allow a pattern to be sewn on the way so that another pattern can be sewn even if the pattern is not completely sewn.

[0005]

In order to solve the above problems, the invention according to claim 1 is, for example, as shown in FIGS. 1 and 2, sewing data storage means for storing sewing data of a plurality of patterns. (ROM 12, ROM card 13), pattern selecting means (operation panel 7) for selecting one or more desired patterns from the plurality of patterns in which sewing data is stored in the sewing data storage means, and cloth Stitch forming means for forming stitches (needle bar, needle 9, embroidery device 8, feed dog),
A sewing machine (1) comprising: a control unit (control unit 11) that causes the stitch forming unit to form a pattern stitch on a cloth based on the stitch data of the pattern selected by the pattern selecting unit.
While forming the stitches of the pattern by the control means,
The formation of stitches is stopped halfway and the sewing is stopped, and at the same time, the pause pattern including at least the unsewn pattern and the pattern being sewn among the patterns selected by the pattern selection means is stored in the pause storage means (flash memory 15). The pause means (control section 11) to be stored, and after the pause of sewing by the pause means,
It is possible to form in the stitch forming means a stitch of another pattern separately selected by the pattern selecting means, and read the rest pattern from the rest storing means, and read the rest pattern stitch data. And a pause control unit (control unit 11) that causes the stitch forming unit to resume stitch formation of a pattern in which sewing has been paused.

Here, the "pattern" formed by the stitch forming means is, for example, a pattern sewn by cloth feed sewing or embroidery sewing described in claim 6 described later. However, it is not particularly limited to these examples.

According to the first aspect of the invention, since the sewing machine is provided with the pause means, the pause pattern is stored in the pause storage means when the sewing of the pattern is stopped halfway and the sewing is paused. . Further, since the sewing machine is provided with the pause control means, it is possible to cause the stitch forming means to form a stitch of another pattern after the sewing pause, and based on the sewing data of the pause pattern stored in the pause storage means. Then, the stitch formation of the pattern for which the sewing is stopped is restarted.

Therefore, in the conventional sewing machine, it is impossible to sew other patterns unless all the sewing of the pattern started at the beginning is completed. However, in the sewing machine according to claim 1, the sewing of the pattern started at the beginning can be performed. Even if not all are finished, it is possible to pause the sewing of the pattern and perform the sewing of another pattern. Further, since the formation of the stitches of the pattern for which sewing has been paused can be resumed by the pause control means, the sewing machine operator may postpone the sewing of the pattern that is currently being performed depending on the situation and sew other patterns. It can be performed. Therefore,
The degree of freedom in sewing machine operation can be further improved compared to the conventional case.

After the intermediate stop screen 107 is displayed at 82, the stitch formation of the pattern in which the sewing is paused is restarted.

Therefore, in the conventional sewing machine, if the sewing of the embroidery pattern is stopped halfway and then another pattern is sewn, it is not possible to restart the sewing of the embroidery pattern that was stopped halfway. In the sewing machine 1 of the embodiment, even if the sewing of the other pattern is performed after the sewing of the embroidery pattern is stopped, based on the pause data stored in the flash memory 15,
It is possible to restart the sewing of the embroidery pattern that was stopped halfway.

In step S57, the operation panel 7
Since the data of all the patterns selected by is stored in the flash memory 15, the entire pattern in which the sewing is stopped can be displayed in the layout section 303e of the pause data determination screen 303 when the sewing is resumed. Therefore, the operator of the sewing machine 1
It is possible to confirm whether the pause pattern for restarting sewing matches the pattern that is actually sewn on the cloth.
In step S82 and subsequent steps, when the suspended embroidery pattern sewing is resumed, the pattern sewing is performed based on the data of all the patterns selected at the time of the suspension. It is possible to sew the suspended embroidery pattern in the same manner as the normal stitch formation of the embroidery pattern without the need.

Further, since the control section 11 sets the resuming position of the suspended embroidery pattern sewing to the same position as the stop position and restarts the sewing from this position, the embroidery sewing can be restarted from an appropriate position. The stitches of the pattern that is sewn up to the middle and the stitches of the pattern that are formed after the sewing is restarted can be continuous.

The flash memory 15 has two holders H1 and H2 for storing the pause data.
Since it is provided for each H2, it is possible to store the pause data for two times. Therefore, when the rest data is stored in the holder H1 and the stitches of other patterns are formed, the sewing of this pattern can be stopped and the rest data can be stored in the holder H2.
The degree of freedom in sewing machine operation can be improved. Also,
Since the holder data can be selected by selecting a holder in the holder display portion 302a of the pause data selection screen 302,
The stitch formation of the desired pattern can be resumed.

Further, even when the sewing of the embroidery pattern is stopped, the main body pattern can be sewn, and the stitch formation of the embroidery pattern can be resumed after the main body pattern is sewn. The operator can change the sewing mode (embroidery sewing mode, main body sewing mode) freely while pausing the sewing of the pattern or sewing other patterns.
It is possible to resume sewing of the suspended pattern.

Further, each screen 20 displayed by the operation panel 7
1 to 203.302.303.401 displays the explanation display section, so that the operation performed on the operation panel 7 can be confirmed by the displayed contents. Therefore,
Even a beginner can easily operate the operation panel 7 to perform sewing pause processing, pause data restoration processing, and the like.

Since the pause data in the holder can be erased in step S94 of the data erasing process,
For example, when the pause data is stored in both of the holders H1 and H2, it is possible to specify the desired holder to erase the pause data and newly store the pause data in this holder.

In the holder display section of the operation panel 7, holders not containing pause data are displayed in white and holders containing pause data are displayed in gray. Which holder contains pause data? , You can easily check if it is not in. Further, since the selected holder (designated holder) is displayed in black, it is possible to easily confirm which holder is selected.

In the above embodiment, the method of suspending the sewing of the embroidery pattern and restarting the sewing is mainly described. However, in the sewing machine 1, the main body sewing is also performed in the case of the above-mentioned embroidery sewing. In the same manner as above, the sewing pause processing, the pause data restoration processing, and the data erasing processing can be performed.

Further, in the flash memory 15, an area for storing the rest data is provided for each of the two holders H1 and H2, but the number of holders may be three or more. It may be one depending on the case.

Further, the pause data stored in the flash memory 15 includes data relating to all the patterns selected in the embroidery sewing general flow, but is not limited to this, and at least sewing has not been completed yet. It suffices that the pause data includes various data related to the unsewn partial pattern and the partial pattern that was being sewn when the sewing was stopped halfway. With this configuration, it is possible to resume the stitch formation of the pattern in which the sewing is paused after the pause data restoration process.

Further, although the pause data is stored in the flash memory 15, the present invention is not limited to this, and the pause data may be stored in the ROM card 13. In this case, the ROM card 13 storing the rest data
Is attached to another sewing machine, the stitch formation of the pattern being sewn by the other sewing machine is restarted, or when the memory capacity of the ROM card 13 is insufficient, another RO machine having a larger memory capacity is used.
It can be replaced with an M card to store rest data. Further, the present invention is not limited to this example, and the battery 14 may be used to temporarily store the pause data in the RAM 14.

Further, when the sewing of the suspended pattern is restarted, the sewing restart position is set to the same position as the sewing stop position. However, the present invention is not limited to this. For example, based on the data of the stop position. The needle drop position, which is a few stitches backward from the stop position, may be set as the sewing restart position. Further, the pause data may be automatically deleted when the sewing of the suspended pattern is resumed.

Further, the respective display screens 101 to 107, 201 to 203, 301 to displayed in the pattern sewing process
The display contents of 303, 401, and 402 can be changed as appropriate. Further, it goes without saying that each configuration of the sewing machine 1 can be appropriately changed without departing from the spirit of the present invention.
