Start switch 1 when in stamp mode
When 2 is turned on, mirror pattern data of a mirror pattern in which the selected embroidery pattern is inverted left and right is created as described later, and embroidery sewing based on the mirror pattern data is executed.

Here, in the embroidery sewing process other than the stamp mode, embroidery sewing is sequentially performed on a plurality of pattern portions having different thread colors using embroidery threads of different colors. In the embroidery sewing process in the stamp mode, ink is easily impregnated. Embroidery sewing is performed in which all patterns are sewn continuously (but may be discontinuous) using embroidery threads of an arbitrary thread color. Therefore, in the stamp mode, the embroidery data of all the pattern portions of the selected embroidery pattern is changed to a series of embroidery data, and the series of embroidery data is subjected to an inversion process described later, and the mirror pattern data is converted. Created.

Next, a routine of the embroidery pattern selection editing sewing process and a routine of the stamp mode switching control will be described with reference to flowcharts of FIGS. In the figure, reference symbol Si (i = 1, 2, 3,...) Indicates each step. As shown in FIG. 8, when the control of the embroidery pattern selection / editing sewing process is started by turning on the power, initial settings such as clearing the memories of the RAM 25 are first performed (S1), and then the above-described operations are performed. Such an embroidery pattern group selection process is executed (S2), and then an embroidery pattern selection process for selecting one or a plurality of embroidery patterns from the selected pattern group is executed (S3). An editing process is performed (S4). On the other hand, after the initialization is executed by turning on the power, the stamp mode switching control by the interval interrupt processing shown in FIG. 9 is started.

When the stamp mode switching control is started, as shown in FIG. 9, it is first determined whether or not a stamp key (the touch key 11 corresponding to the key mark "stamp") is ON (S10). Is YES, the flag F
Is set to 1 (S11), then it is determined whether or not the cancel key (the touch key 11 corresponding to the key mark "cancel") is ON (S12). If the determination is Yes and the flag F is set. (S13: Yes), the flag F is cleared (S13).
14) Return.

Referring again to FIG. 8, when the start switch 12 is turned on after the end of the pattern editing process in S4 (S5: Ye).
s) The sewing process (S6) is started. The subroutine of the sewing process will be described with reference to FIG. 10. First, when the sewing process is started, it is determined whether or not the stamp mode flag F is set (S20). , In the stamp mode), the embroidery data of the selected embroidery pattern data stored in the RAM 25 is read (S2).
2) After executing the process of changing to a series of embroidery data as described above, the embroidery data left / right inversion process for right / left inversion of the embroidery pattern is executed (S22).

The embroidery data left / right inversion process will be described with reference to FIGS. Of the plurality of coordinate data included in the embroidery data, the first coordinate data indicating the first needle drop position is the absolute coordinate data from the origin O, and each of the other coordinate data is the increase or decrease of the coordinate value. Is relative coordinate data. For example, a needle drop point based on a plurality of pieces of coordinate data of the embroidery data of the embroidery pattern of the character “B” does not protrude outside the character area shown by a solid line in FIG. Data is calculated, and the maximum value X of X is calculated based on the absolute coordinate data.
And the minimum value Xmin.

Next, X of each coordinate data (X, Y) in the embroidery data is rewritten to -X, and the coordinate data (-X,
Y). Next, as shown in FIG. 12, when the character indicated by the chain line is translated in the + X direction by (Xmax + Xmin), it becomes mirror pattern data of the embroidery pattern "B". After all, the coordinate data (X,
When Y) is converted into (−X + Xmax + Xmin, Y), the embroidery pattern becomes mirror data obtained by inverting the embroidery pattern from side to side.

In FIG. 10, when the embroidery data left / right reversal process in S22 is completed, thread tension adjustment control is executed (S23), the drive of the thread tension stepping motor 20 is controlled, and the tension applied to the upper thread is slightly relaxed. Can be This is to prevent the upper thread (embroidery thread) from being excessively tightened, and to sufficiently raise the embroidery stitches that become the stamped surface protrusions of the stamped surface portion of the stamp on the surface of the sheet material 41. is there. Next, in S24, embroidery sewing is performed on the same sheet material 41 as described above based on the mirror pattern data, and then the embroidery pattern selection editing sewing process ends. On the other hand, S2
If the stamp mode flag F is not set at 0 (S20: No), the embroidery data of the pattern data of the selected embroidery pattern is read from the RAM 25 (S2).
5) The embroidery sewing based on the embroidery data is executed, and the embroidery pattern selection editing sewing process ends.

In the stamp mode, the embroidery data is changed so that the line width of the embroidery stitch becomes wider after the embroidery data is turned left and right in S22, and the embroidery sewing is executed based on the embroidery data. Is also good. For setting the stamp mode, a stamp mode changeover switch is provided on the operation panel 29, and this switch is turned ON / OFF.
The stamp mode may be switched by the F operation. As described above, after the embroidery stitch obtained by inverting the selected embroidery pattern on the sheet material 41 is embroidered, the sheet material 41 is fixed to the stamp side 43a of the stamp base 43 to manufacture the stamp 40. .

Next, a modified embodiment in which the above-described embodiment is partially modified will be described. However, the same components as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. 1] In the stamp 40A according to the first modification, as shown in FIG. 17, a synthetic resin foam, a synthetic rubber foam, a nonwoven fabric, or the like is formed on the surface of the sheet material 41 similar to the above embodiment, on which the embroidery sewing is performed. By performing embroidery sewing in a state in which the porous material sheets 51 which are easily impregnated with the ink are stacked (see FIG. 18),
The porous material 51a of the porous material sheet 51 is sewn inside the embroidery stitch forming the stamp surface convex portion 51 of the stamp surface portion 50.
The stamp 40A is manufactured basically by the same apparatus and method as described above.

At the time of embroidery sewing, the thread tension mechanism is adjusted so that the tension of the upper thread is further reduced than in the above case, so that the porous material sheet 51 sewn inside the sewing needle is not excessively tightened. Embroidery sewing. After the embroidery sewing, the extra porous sheet 51 outside the embroidery seam is to be removed. According to the stamp 40A, the stamp face convex part 52 is greatly raised by the porous material 51a, so that the raised print convex part 52 enables very fine printing. In addition, since a small amount of ink can be impregnated in the porous material 51a, printing can be continuously performed a plurality of times without replenishing ink after the ink impregnation.

2] In the stamp 40B of the second modification, as shown in FIG. 19, similarly to the stamp 40A, it is easy to impregnate the ink inside the embroidery stitch forming the stamp face convex part 52 of the stamp face part 58. In addition to sewn the porous material 51a, the stamp base 43B accommodates the porous material 56 impregnated with ink, and supplies the ink to the porous material 51a sewn inside the embroidery stitch. It is configured so that printing can be performed without replenishing ink.

The stamp base 43B is formed to have an open lower end in which an ink container 55 is formed.
5 stores a porous material 56 impregnated with ink, and the lower end of the ink storage portion 55 is covered with a hard porous material 57. The sheet material 41B is made of a cloth through which ink can easily pass, and is fixed to the lower surface of the hard porous material 57. An adhesive or the like is applied to the surface of the portion other than the stamped surface convex portion 52 of the stamped surface portion 58 so as to prevent the ink from oozing out. According to the stamp 40 </ b> B, stamp printing can be performed a plurality of times without applying ink to the stamp surface convex portion 52 from outside.

Next, an embodiment relating to a stamp recording medium according to the present invention will be described. As shown in FIGS. 20 to 22, this embodiment is an example in which the present invention is applied to a ROM card detachably mounted on the embroidery sewing machine M of the above embodiment, and is the same as the above embodiment. The following description will be made by assigning the same reference numerals to the components. However, embroidery sewing machine M
It is assumed that the control program for the embroidery pattern selection edit sewing process in the ROM 24 of the control device C does not store the subroutine for the embroidery data left / right inversion process.

As shown in FIG. 20, a ROM card 70 corresponding to a stamp recording medium has the ROMs 24, 2
8 is the pattern data of a plurality of embroidery patterns similar to the plurality of embroidery patterns stored therein, and the mirror pattern data obtained by reading out the embroidery data of the designated embroidery pattern from the pattern data and inverting the embroidery pattern. A control program for inversion processing control for creating mirror pattern data for sewing an embroidery pattern forming a stamped surface portion of a stamped portion of a stamp is recorded.

The pattern data of a plurality of embroidery patterns are recorded in the order of first pattern data, second pattern data, third pattern data, and so on. The pattern data of each embroidery pattern includes embroidery data, pattern display data, and its accompanying data. When sewing an embroidery stitch as a stamped surface of a stamp, the embroidery data of each embroidery pattern is a series of embroidery data that is not classified according to the pattern of each color because of embroidering with one color embroidery thread. As shown in FIG. 21, each piece of embroidery data includes a plurality of coordinate data indicating a position (needle drop position) for moving the embroidery frame 34 and a stop code designating the end of the embroidery data.

When the power of the sewing machine M is turned on in a state where the ROM card 70 is mounted on the slot 2a of the embroidery sewing machine M and connected to the card connector 13, the control program for the reversal processing recorded in the ROM card 70 Is read, and the ROM card 70 is read out based on the control program.
The embroidery data of the designated embroidery pattern is read from among the plurality of embroidery pattern data recorded in the embroidery pattern, and mirror pattern data of a mirror pattern obtained by inverting the embroidery pattern is created.

Next, the inversion processing control routine will be described with reference to the flowchart of FIG. However,
In the figure, reference symbol Si (i = 30, 31, 32,...) Indicates each step. When the inversion processing control is started, first, RO
The control program for inversion processing control recorded on the M card 70 is read and stored in the RAM 25 (S30).
Next, the pattern data of the designated (selected) pattern among the pattern data recorded on the ROM card 70 is read (S31), and is displayed on the display 10 based on the pattern display data and the accompanying data of the pattern data. The designated pattern and its associated information (sewing time etc.) are displayed (S3
2). Next, based on the plurality of pieces of coordinate data of the read embroidery data, the absolute coordinate data is calculated in the same manner as described in the above embodiment, and the maximum value X of X is calculated based on the absolute coordinate data. The minimum value Xmin of X is calculated (S33). The designation (selection) of the embroidery pattern is performed in the same manner as in the above-described pattern selection processing.

Thereafter, the counter P stored while being updated in the memory of the RAM 25 is set to 1 (S34), and then the P-th coordinate data (Xp, Y) in the embroidery data is set.
p) is read (S35), and its coordinate data (Xp, Y
p) is converted to (-Xp + Xmax + Xmin, Yp) and stored in the sewing data memory of the RAM 25 (S3).
6). Next, the counter P is incremented by 1 (S
37), it is determined whether or not the read embroidery data is a stop code (S38). If the read embroidery data is not a stop code (S38: No), the process returns to S35, and S35 to S38 are repeated. This control is terminated when the inversion process is performed and the determination in S38 becomes No. Thus, all the coordinate data of the embroidery data of the designated embroidery pattern is rewritten to the mirror pattern data.

The embroidery pattern can be formed by embroidering a sheet material or the like by effectively utilizing pattern data of a desired embroidery pattern among a large number of embroidery patterns provided in an embroidery sewing device such as an embroidery sewing machine. A stamp that can be printed is obtained, and a stamp that can be manufactured easily and inexpensively and that can be manufactured in each home is obtained.

According to the second aspect of the present invention, since the porous material which is easily impregnated with ink is sewn into the embroidery stitch forming the stamp face convex portion, the embroidery stitch as the stamp face convex portion is greatly raised. Therefore, the printing performance of the convex portion of the stamp surface can be enhanced, and the porous material can be impregnated with the ink, so that the stamp can be continuously printed a plurality of times after the ink is supplied. The other effects are the same as those of the first aspect.

According to the stamp manufacturing method of the third aspect,
The embroidery stitch corresponding to the stamped surface of the stamped surface of the stamp is sewn on the sewable sheet material, and the stamped material can be easily and easily fixed to the stamped surface on the stamped surface of the stamp base. It can be manufactured at low cost. During the sewing process, embroidery stitches can be easily formed on the sheet material using an embroidery sewing device such as an embroidery sewing machine, and the pattern data of a large number of embroidery patterns provided in the embroidery sewing device can be effectively used. Further, the embroidery stitches as the stamp surface convex portions can be easily formed.

According to the stamp manufacturing apparatus of the fourth aspect,
Pattern data storage means for storing pattern data of a plurality of embroidery patterns; and embroidery for sewing embroidery on a sheet material based on the pattern data read out from the pattern data storage means to form a stamp face convex part of a stamp face of the stamp. Since the sewing machine includes the sewing means, the desired embroidery stitches of the plurality of embroidery patterns can be easily formed on the sheet material by the embroidery sewing means, so that the stamp can be manufactured very easily and inexpensively. it can. In particular, since an embroidery sewing device such as an embroidery sewing machine can be applied as a stamp manufacturing device, it is possible to easily manufacture a stamp capable of stamp-printing a desired pattern among a large number of embroidery patterns.

According to the recording medium for stamps of the fifth aspect,
A recording medium for a stamp applicable to an embroidery sewing device such as an embroidery sewing machine is obtained. The control device of the embroidery sewing apparatus reads the reversal processing control program from the recording medium for the stamp, reads out the designated pattern data from the plurality of stored pattern data, and reads the stamped portion of the stamped portion of the stamp. Mirror pattern data for sewing the embroidery pattern to be formed can be created. Embroidery stitches are sewn on a sewable sheet material based on the created mirror pattern data,
If the sheet material is fixed to the bottom surface on the stamp side of the stamp base, the stamp can be manufactured very easily and at low cost. Since the embroidery stitches are formed based on the mirror pattern data, the embroidery patterns can be printed in a normal non-reversed state, which is advantageous in forming the embroidery stitches of an asymmetric embroidery pattern such as a character as a stamp surface convex portion. is there.
