Next, the operation of the present invention will be explained with reference to the flow chart of FIG.

This flowchart starts when a power switch (not shown) is turned on.

Next, in step (a), if you press the desired key on the keyboard note 12''2 of the pattern selection section 5 with your finger, +ji
The connecting portion of the keyboard 11 is elastically deformed and the key switch 10 is pressed to output a desired key signal.

Next, in step (b), it is determined whether the operated key is a key on the storage registration section.

If the key is not on the memory registration section, it is determined in the next step (C) whether or not it is a pattern selection key. If the operated key is a key other than the pattern selection key, it is determined in step (d) whether or not it is a memory key. In the case of keys other than the memory key, other processing is performed in step (e), and the key is moved to the input side in step (a). If the operated pattern selection key is the pattern selection key, in step (f), the display data of the pattern is read out from the pattern data storage means 18 and displayed on the selected pattern display section 6, as well as the pattern number indicating the pattern. is temporarily held in the holding section of the heading selection pattern storage means 17.

Next, in step (g), it is determined whether or not to form a seam. This means that if the sewing machine starting means is operated subsequently, it is determined that a stitch has been formed, and in the next step (h), the pattern number held in the holding section of the selected pattern storage means 17 is The needle amplitude control data and feed adjustment control data of the corresponding pattern data are read out to form pattern stitches.

If it is determined that no stitches are to be formed in step (g) above, that is, if the sewing machine starting means is not operated and a new key is pressed manually, the pattern selected in step (b) above is combined. Determine whether to memorize or not. If the memory key 7 is operated in step (b), it is determined to be stored in step (d), and the selected pattern is stored and registered in the selected pattern storage means 17 in step (i). Next, in step (g), it is determined whether or not to form a seam.

The termination is determined by the termination signal generated by operating the storage termination key on the oil level panel 4.

Next, a case where the combination of characters rABcDj is created manually will be explained.

If the pattern selection key rAJ of the pattern selection section 5 is pressed manually in the step (a) described above, it is determined that the key is not on the memory registration section in the step (b) described above, and the next step ( In step C), it is determined whether it is a pattern selection key or not, and since it is a pattern selection key, pattern A is displayed on the selected pattern display section 6 in step D, and the pattern number of A is selected from the top. It is temporarily held in the holding section of the pattern storage means 17.

Next, when the memory key 7 for storing data is operated in step (g), it is determined that a seam is not being formed, and the process moves to the input side of step (b) described above, and the memory registration section is displayed. Determine whether the key is The memory key is the following (
In step d), it is determined whether the key is a memory key or not. Since it is a memory key, the selected pattern memory means 1 is stored in step (i).
The selection pattern rAJ temporarily held in 7 is stored. Next, in step (g), when the next pattern selection key rBJ is pressed and the key is pressed manually, it jumps to the input end in step (b) mentioned above and determines whether it is a key on the memory registration section or not. do.

Since it is not a key on the memory registration section, it is determined in the next step (C) whether or not it is a pattern selection key. Since rBJ is a pattern selection key, in the next step (f), the display data of rBJ is read out from the pattern data storage means I8 and displayed on the selected pattern display section 6, and the pattern number is stored in the selected pattern storage means 17. Temporarily hold it in the holding part.

Next, when the memory key 7 is operated in step (g), it is determined that a stitch is not being formed, and the process jumps to the input side of step (b). In step (b), it is determined that the key is not on the memory registration section, so the next step (C
) It is determined whether or not it is a pattern selection key, and since it is a memory key, it is determined to be a memory key in the next step (d), and it is temporarily held in the selected pattern storage means 17 in step (i). The selection pattern "B" is memorized.

In the same way, select pattern "C" one after another and "memorize" it.
By selecting and "memorizing" J, the combination characters rABCDJ are stored in the selected pattern storage means 17 in the order of combination characters rABCDJ.

When the sewing machine starting means is operated in step (g) after the last character rDJ is memorized in step (+), it is determined that a stitch is to be formed, and the patterns are read out from the selected pattern storage means 17 in the order in which they were stored. The pattern data storage means 1
Read the pattern data of the pattern from 8 and write the combination character “Δ
Form the BCDJ seam. After seam formation or as described above (g
When a keystroke is made to register this combination of characters in step ), the process jumps to the input side of step (b) described in 111j.

When it is determined in step (b) that the key on the memory registration section has been operated, it is determined in the next step (D) whether or not the registration card 14 is inserted.The registration card detection means 15 detects the registration card. When not doing so, use "pattern selection mode"
According to the program of the pattern selection program storage means 35, the key of the registration/combination part 5a is a pattern selection key of the pattern displayed on the keyboard sheet (small), and when operated, the displayed pattern becomes a signal indicating that the pattern has been selected; (f)
The selected pattern will be displayed in step . Said registration card I4
is attached, and when the registered card detection means 15 detects the registered card, the "memory registration mode-" is selected, and the key of the registration combination section 5a is activated according to the program of the pattern selection program storage means 35. is a memory registration key and serves as a memory registration signal.

Next, in step (k), it is determined whether or not the selected pattern storage means 17 stores a pattern to be registered. Since rABcl)J is registered in the selected pattern storage means, it is determined that it is the registration mode, and the registration process is performed in the next step (W).
For example, it is registered in the combination pattern storage means I9 in association with Ml.

Since the combination pattern storage means is a read-only memory in which data can be electrically rewritten, the stored contents are retained until rewritten regardless of whether the power is turned off or on.

Next, a case will be described in which a pattern is formed by reading registered combination patterns. The process starts by attaching the registration cart 14 and turning on the power. In step (a), when a key in the registration/registration section 5a''2 on the pattern selection section 5, for example MI, is operated, it is determined whether or not the key operated in step (b) is a key on the memory registration section. Then, in step (D), it is determined whether or not the registration card is installed. Since it is installed, it is determined that the registration mode is set, and the pattern is stored in the selected pattern storage means 17 in the next step (k). If the pattern is not stored, it is determined that the mode is for reading the registered pattern, and in the next step (m), the pattern associated with the key Ml on the memory registration section is determined. is stored in the Moeki combination pattern storage means 19. If it is not stored, in the next step (n), display data, "
"No pattern registered" is read out and displayed on the selected pattern display section 6, and the process jumps to the input end of step (b) described above.

If the pattern is stored in the step (m), the registered pattern is read out in the next step (p) and the pattern is displayed on the selected pattern display section 6 based on the display data. Next, when the minon starting means is operated in step (g), it is determined that a stitch is to be formed, and pattern data corresponding to the read pattern is sequentially read out from the pattern data storage means I8 to form a stitch of the registered pattern. Form.

In this embodiment, when the pattern to be registered is stored in the selected pattern storage means I7, the pattern is stored immediately regardless of whether it has already been registered in the combination pattern storage means 19. Although we have shown the contents to be registered, if the pattern has already been registered in relation to the key on the memory registration section, select [Change the registered contents of Moe] Select Messeno called Rikizutsu Pattern display section 6 If the registered contents are to be changed, the registered contents may be changed and stored by operating the storage key 7.

Note that when the registration card 14 is attached, the keyboard note on the registration card! Since the rightmost column portion of No. 2 is transparent and can be visually recognized, it is effective to write the registered contents on the registration card 14 in order to read the registered contents while viewing them.

In this embodiment, the storage registration display section is set in the rightmost column of the keyboard note 12, but the registration section may be set for a plurality of columns.

(Effects) As described above, according to the present invention, the pattern selection section is switched between the pattern selection mode and the pattern registration mode by attaching and detaching the registration card, and the desired combination pattern is registered in the electrically switchable read-only memory. In addition, it is possible to read out the combination patterns registered in advance, thereby allowing pattern stitches to be formed by reading out the combination patterns registered in advance at any time.
