Next, the operation of the present invention will be described with reference to the flowchart of FIG.

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

Next, in step (a), when a desired key on the keyboard sheet 12 of the pattern selecting section 5 is pressed with a finger, the connecting portion of the keyboard frame 11 is elastically deformed and the key switch 10 is pressed.
Is pressed to output a signal of a desired key.

Next, in the step (b), it is determined whether or not the operated key is a key on the storage registration unit.

If the key is not a key on the memory registration unit, it is determined whether or not the key is a pattern selection key in the next step (c). If the operated key is a key other than the pattern selection key, it is determined in step (d) whether or not the key is a storage key. In the case of a key other than the storage key, other processing is performed in the step (e), and the process jumps to the input side of the step (a). When the operated pattern selection key is operated, the display data of the pattern is read out from the pattern data storage means 18 in step (f), and is displayed on the selected pattern display section 6 and a pattern number indicating the pattern is displayed. Is temporarily stored in the storage unit of the selected pattern storage unit 17.

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

If it is determined in step (g) that stitch formation is not performed, that is, if a new key input is made without operating the sewing machine starting means, the pattern selected in step (b) is combined. It is determined whether or not to store. If the storage key 7 is operated in the step (b), it is determined to be stored in the step (d), and is stored and registered in the selected pattern storage means 17 in the next step (i). Next, in step (g), it is determined whether or not a stitch is to be formed.

The end is determined by an end signal generated by operating the storage end key on the front panel 4.

Next, a case where the combination character "ABCD" is input will be described.

When the pattern selection key "A" of the pattern selection unit 5 is pressed and input in the step (a) described above, it is determined that the key is not a key on the storage registration unit in the step (b), and the determination is made as follows. In the step (c), it is determined whether or not the key is a pattern selection key. Since the key is a pattern selection key, the pattern A is displayed on the selected pattern display section 6 in the step (f) described above, and the pattern number of A is changed. The data is temporarily stored in the storage unit of the selected pattern storage unit 17.

Next, when the storage key 7 for storing data is subsequently operated in step (g), it is determined that the stitch is not formed, and the process jumps to the input side of the above-described step (b), and the data is stored in the storage registration unit. Key is determined. Since it is a storage key, it is determined in the next step (d) whether or not the key is a storage key. Since it is a storage key, the selected pattern storage means is used in step (i).
The selected pattern “A” temporarily stored in 17 is stored. Next, in the step (g), when the next pattern selection key "B" is pressed and a key input is made, the process jumps to the input side in the step (b) to determine whether or not the key is on the memory registration unit. Is determined.

Since the key is not a key on the memory registration unit, it is determined whether or not the key is a pattern selection key in the next step (c). Since "B" is a pattern selection key, the display data of "B" is read out from the pattern data storage means 18 in the next step (f), displayed on the selected pattern display section 6, and the pattern number is set to the selected pattern. The data is temporarily stored in the storage unit of the storage unit 17.

Next, when the memory key 7 is operated subsequently in the step (g), it is determined that the stitch is not formed, and the process jumps to the input side of the step (b). In the step (b), it is determined that the key is not a key on the storage registration unit, so it is determined in the next step (c) whether the key is a pattern selection key. It is determined that the selected pattern is a storage key, and the selected pattern "B" temporarily stored in the selected pattern storage means 17 is stored in the step (i).

Similarly, the patterns “C” are successively selected and “stored”, and “D” is selected and “stored”, so that the combination pattern “ABCD” is stored in the selected pattern storage unit 17 in the order.

When the sewing machine starting means is operated in step (g) after the last character "D" is stored and processed in step (i), it is determined that a stitch is to be formed. And reads the pattern data storage means 18
Read the pattern data of the pattern from
Form the "D" seam. After the formation of the stitches or in the step (g), if a key input is made to register this combination character, the process jumps to the input side in the step (b).

If it is determined in step (b) that a key on the memory registration has been operated, it is determined in next step (j) whether or not the registration card 14 is mounted. The registration card detecting means
When the registration card 15 is not detected, it is in the "pattern selection mode" and the key of the registration / shared section 5a is a pattern selection key of the pattern displayed on the keyboard sheet (small) according to the program of the pattern selection program storage means 35. Then, the display pattern becomes a signal of pattern selection by the operation, and the selected pattern is displayed in the step (f). When the registration card 14 is mounted and the registration card detection unit 15 detects the registration card, the operation is in the “storage registration mode”, and the registration / shared unit is operated according to the program of the pattern selection program storage unit 35. The key 5a is a memory registration key, and serves as a memory registration signal.

Next, in the step (k), it is determined whether or not a pattern to be registered is stored in the selected pattern storage means 17. Since "ABCD" is registered in the selected pattern storage means, the mode is determined to be the registration mode, and registration processing is performed in the next step (l), and "ABCD" is operated on the key on the storage registration unit, for example, M1. It is registered in the combination pattern storage means 19 in association therewith.

The combination pattern storage means is a read-only memory capable of electrically rewriting data, so that the stored contents are retained until rewriting regardless of whether the power is turned on or off.

Next, a case in which a registered combination pattern is read out to form a pattern will be described. The operation starts when the registration card 14 is mounted and the power is turned on. When a key, for example, M1 on the registration / shared unit 5a of the pattern selection unit 51 is operated in the step (a), it is determined whether or not the key operated in the step (b) is a key on the storage registration unit. Next, in the step (j), it is determined whether or not the registration card is mounted. Since it is mounted, it is determined that the mode is the registration mode, and it is determined whether or not a 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 the readout mode of the registered pattern, and in the next step (m), the pattern associated with the key and M1 on the storage registration unit is stored in the combination pattern storage means 19. It is determined whether or not there is. If it is not stored, in the next step (n), the display data, "No pattern is registered", is read from the pattern data storage means 18, displayed on the selected pattern display section 6, and displayed in the above (b). Jump to the input side of the step.

If a pattern is stored in the above-mentioned 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 sewing machine starting means is operated in step (g), it is determined that a stitch is to be formed, and the pattern data corresponding to the read pattern is sequentially read from the pattern data storage means 18 to register the stitch of the registered pattern. Form.

In the present embodiment, when a pattern to be registered is stored in the selected pattern storage unit 17, the pattern is immediately stored regardless of whether or not the pattern is already registered in the combination pattern storage unit 19. Although the contents to be registered are shown, if a pattern has already been registered in relation to the key on the memory registration unit, a message "Do you want to change the previous registration contents?" When the registered content is changed in response to this, the registered content may be changed and stored by operating the storage key 7.

When the registration card 14 is attached, the rightmost row of the keyboard sheet 12 on the registration card 14 is formed transparent and can be visually recognized. It is effective to fill in the registration details in In this embodiment, the memory registration display section is set in the rightmost column of the keyboard sheet 12, but the registration section may be set in a plurality of rows.

(Effects) As described above, according to the present invention, the pattern selection unit is switched between the pattern selection mode and the pattern registration mode by inserting and removing the registration card, and the desired combination pattern is registered in the electrically rewritable read-only memory. Can be read,
This makes it possible to arbitrarily read out a combination pattern registered in advance and form a pattern stitch.
