2. The storage area in the RAM 44 is allocated not only to control registers but also to SD registers for sequentially storing selected pattern information groups. In addition to the control program, a plurality of pattern information groups each including embroidery and twill data for forming a stitch pattern corresponding to the data key 38 are stored in advance in the memory in the ROM 46 in detail.

Therefore, the ROM 46 is a storage means for storing a large number of groups of pattern information. This group of pattern information includes, as shown in FIG. This includes bristle stitch data consisting of a plurality of stitch data indicating needle positions. The price calculation data consists of the number of stitches B of the stitch pattern, the unit price PM per stitch pattern, the basic charge PMB for each pattern, the unit price PH per stitch, and the basic charge PH8 for each number of stitches. ing. Further, each stitch data consists of a pair of x displacement data and Y displacement data in order to specify the needle position. The x displacement data and Y displacement data represent the amount of movement of the work holder 20 in the x-axis direction and the y-axis direction, respectively. The operation of this embodiment will be explained below.

First, the power is turned on and the work cloth 19 is attached to the work holder 20.

Then, by operating the data key 38, stitch density key 36, and size key 34, data regarding the type, stitch density, and size of each stitch pattern for forming a desired embroidery pattern is input. This data input operation is performed in the fourth step along with the charge calculation operation and pattern formation start operation described later.
Processing is performed according to the control program shown in the figure and stored in advance in the ROM 46. That is, when any of the data key 38, stitch density key 36, size key 334, charge calculation command key 30, and start key 28 is not operated, the signals AKD and AKD of the input boat 40 are not operated.
DDS, SDS, PDS and ESS are controlled by registers (
The step PSI for reading into the accumulator) and the following steps PS2 to PS6 are executed sequentially and repeatedly. These steps PSI to PS6 form a monitor loop 66 that monitors whether or not the keys 28, 30, 34, 36, and 38 have been operated. here,
When the data key 38 is operated, steps PS7 to PS9 are executed according to the determination at step PS2.

That is, in step PS7, the code signal KD supplied to the input port 40 is sent to the control register, and in step PS8, the code signal KD is sent to the control register.
A group of pattern information corresponding to the stitch pattern represented by D is stored in the ROM.
46 and sequentially stored in the SD register of the RAM 44, and in the subsequent step PS9, a display signal PD corresponding to the stitch pattern represented by the pattern information is output from the output port 42 based on the pattern information stored in the SD register. The stitch patterns engraved on the operated data keys 38 are outputted to the display drive circuit 56 and displayed on the display device 12 in the order of the operations. For example, when each alphabet key on which "A", "B" and "C" are engraved in the data key 38 is pressed, the stitch pattern information corresponding to each alphabet key is stored in the SD register. The alphabet letters "A", "B" and "CJ" are displayed on the dot matrix display board 14. FIG. 5 shows this state. Next, when the size key 34 is operated, step PS3 Step PSIO according to the judgment of
and me 1 1 is executed. That is, the size key 34
is operated, and when the numerical keys in the data keys 38 are inputted as appropriate to correspond to the size of the desired stitch pattern, a code signal KD corresponding to the input operation is output at step PS1. The code signal KD that is supplied to the input port 40 and represents the code number is stored in the control register, and in step 11, the code signal K
The contents of the pattern information group stored in the SD register are modified based on numerical data corresponding to the size of the stitch pattern represented by D. This modification process is performed, for example, on the ROM46
If the numerical data representing the desired size of the stitch pattern is twice the size of the stitch pattern for which the pattern information group stored in the embroidery stitch data is used as is, then This is done by rewriting the contents of a pair of X displacement data and Y displacement data constituting the stitch data to double the amount of movement. Next, when the stitch density key 36 is operated, step PS12 is performed according to the determination in step PS4.
and PS13 are executed.

That is, after the stitch density key 36 is operated, the code number corresponding to the desired stitch density of the stitch pattern is displayed in the data key 3.
8, the code signal KD that is supplied to the input board and represents the desired stitch density is read out to the control register in step PS12, and the code signal KD that corresponds to the stitch density that the code signal KD represents is read out in step PS13. The contents of the pattern information group stored in the SD register are modified based on numerical data. In this modification process, for example, for a stitch pattern in which the pattern information group stored in the ROM 46 is used as is, the numerical data representing the desired stitch density is further changed to a rough stitch pattern with half the stitches. If it indicates that a stitch is to be formed, this is done by skipping the individual stitch data in the embroidery stitching data and halving the number of stitches B in the charge calculation data. Once the stitch pattern necessary for embroidery sewing has been selected, the size of the stitch pattern, and the stitch density have been set through the above operations, the charge calculation command key 30 is used to display the charge required for the embroidery warp. is manipulated.

When the toll calculation command key 30 is operated, step 14 is executed according to the judgment in step PS5 of the control program, and the calculation type switching signal tower S supplied to the input port 401 is read out to the control register. In this state, the arithmetic expression switching key 32 is operated to select a desired arithmetic expression from either the arithmetic expression based on the number of stitch patterns or the arithmetic expression based on the number of stitches. ing. For example, if the calculation formula key 32 is operated to select a calculation formula based on the number of stitch patterns, steps PS16 to P
S18 is executed. That is, in step PS16, the number N of stitch patterns selected is calculated based on the contents of the SD register, and in the subsequent step PS
17, the price FM based on the number of stitch patterns
is calculated according to the following equation '1' based on the contents of the SD register. FM=N×PM+PMB '1'
The selected stitch pattern is the above-mentioned stitch pattern “A” and “B”.
C", if the unit price PM per stitch pattern is 3q and the basic charge PMB is 100 yen, the number N of stitch patterns is 3, so the charge FM'ma'1} From the formula, q is 19.

Then, in step PS18, a display signal PD representing the charge FM is sent from the output boat 42 to the display drive circuit 56, and the charge Fw is displayed on the display device 12. 6th
The figure shows this situation. On the other hand, if the calculation formula switching key 32 is operated to select the calculation formula based on the total number of stitches included in all the selected stitch patterns, step PS1
Steps PSI9 to PS21 are executed according to the determination in step 5.

That is, the total number of stitches BN is calculated by adding the number of stitches of all the stitch patterns selected in step PSI9. For example, if the selected stitch pattern is the above-mentioned "A",
In the case of “B” and “C”, BN=B^+BB×B
c'2}.

Here, BA, BB, and Bc are the respective numbers of stitches included in the pattern information group corresponding to the stitch patterns in the SD register. In the following step PS20, the charge FM is calculated using the following formula '3} based on the contents of the SD register.
'It is calculated accordingly. FH=BN×PH×PHB
'3'For example, if the number of stitches B^, BB, and Bc of the stitch pattern are 40 each, the unit price per stitch is 1 yen, and the basic charge is 100 yen, then the total number of stitches BN is calculated from the formula 120, and the charge FH is 22 from formula '3}.
Becomes biq.

Then, in step 21, a display signal PD representing the charge FH is outputted from the output port 42 to the display drive circuit 56 and displayed on the display device 12. In this state, when the start key 28 is operated, the embroidery sewing routine in step PS22 is executed according to the determination in step PS6, and the selected stitch pattern is formed on the work cloth according to the desired size and stitch density. be done.

That is, the needle 18 is driven up and down by the sewing machine motor 16, and the When the needle is outputted to the X-axis drive circuit 60 and the Y-axis drive circuit 62 in synchronization with the movement, the needle position on the workpiece cloth 19 is sequentially positioned each time it moves up and down, and the desired stitch pattern is embroidered. Ru. Such an operation is repeated for each start code, and ends at the end of the stitch data in the final group of pattern information. Therefore, all the selected stitch patterns, for example, "ABC" embroidery, are formed on the work cloth 19. Then, when the execution of step PS22 is completed, step PSI is executed again.
is executed from. As described above, according to the present embodiment, a reasonable charge can be easily calculated based on the number of stitch patterns selected for embroidery processing or the total number of stitches of all stitch patterns. Since the charges are displayed, the burden on the operator is reduced, and at the same time, customers can gain confidence in the details of the charge calculation, eliminating their dissatisfaction with the charges.

It should be noted that the above is just one embodiment of the present invention,
The present invention can be modified in various ways without departing from its spirit.

For example, the unit price P of the arithmetic expression '1} in the above embodiment
N or basic charge PMB is common to each stitch pattern, but
Different values may be used depending on the difficulty or size of each stitch pattern.

Furthermore, in the above embodiment, when calculating the fee FH based on the total number of stitches of the selected stitch pattern, it is possible to round off to the nearest q unit and remove fractions of 1 yen or less.

Furthermore, although the relative movement between the needle 18 and the workpiece cloth 19 in the above-mentioned embodiment is performed by two work holders,
An automatic sewing machine equipped with a mechanism for swinging the needle 18 may be used.

Effects As detailed above, according to the automatic sewing machine equipped with the price display device of the present invention, the price is automatically displayed based on the number of stitch patterns selected for embroidery processing or the total number of stitches. As a result, the burden on the operator associated with charge calculation is eliminated, and the excellent effect of gaining customer confidence in the embroidery charge is produced.
