A search process (step number search process) for searching for sewing pattern data is performed (step S204).
The control unit 10 also receives pattern name data input via the pattern name data input key 3 (character input key 7, see FIG. 7) on the search item setting screen (see FIG. 6) displayed on the operation panel 16. A search process (name search process) for searching for the sewing pattern data that can be specified based on is performed (step S205).

Next, the control unit 10 determines whether or not an enter button (confirmation key) (not shown) has been pressed (step S206).
When the control unit 10 detects a pressing signal indicating that an enter button (not shown) has been pressed and determines that the enter button has been pressed (step S206; Yes), it corresponds to the search item set by the operation input on the search item setting screen. The search process for searching for the sewing pattern data is terminated.
On the other hand, if the control unit 10 does not detect a pressing signal indicating that an enter button (not shown) is pressed and determines that the enter button is not pressed (step S206; No), the process proceeds to step S207.

In step S207, the control unit 10 determines whether or not a cancel button (not shown) has been pressed (step S207).
If the control unit 10 does not detect a press signal indicating that a cancel button (not shown) is pressed and determines that the cancel button is not pressed (step S207; No), the process returns to step S206.
On the other hand, when the control unit 10 detects a press signal indicating that a cancel button (not shown) is pressed and determines that the cancel button is pressed (step S207; Yes), a selection screen (for example, stored in the memory M1 of the EEPROM 10d) The display content (setting content) of the selection screen shown in FIG. 5 is stored in the memory M2 of the EEPROM 10d (step S208), and sewing pattern data corresponding to the search item set by the operation input on the search item setting screen is stored. The search process for searching is terminated.

  Thus, the search process for searching for the sewing pattern data is performed so as to correspond to various search items.

  Next, in steps S202, S203, S204, and S205, search item setting processing for selecting desired sewing pattern data corresponding to each search item, and sewing pattern data corresponding to the set search item are searched. The search processing to be performed will be described based on the flowcharts shown in FIGS.

The control unit 10 inputs the classification data for gentlemen or women via the distinction data input key 4 (gentleman key 4b, lady key 4c) on the search item setting screen (see FIG. 6) displayed on the operation panel 16. It is determined whether gentleman / woman selection has been made (step S301).
When the control unit 10 determines that the gentleman / woman selection has not been made (step S301; No), the control unit 10 cancels the processing related to the gentleman / woman selection, and re-searches the sewing pattern data under the previous conditions. The search results are stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data numbers (step S302), and the search processing of the sewing pattern data relating to gentleman / woman selection is completed.
On the other hand, when the control unit 10 determines that the gentleman / women selection has been made (step S301; Yes), the control unit 10 selects the gentleman / women selected based on the entered gentleman / women discrimination data. The sewing pattern data corresponding to the type is searched (step S303).

Next, as a result of the search, the control unit 10 determines whether there is sewing pattern data corresponding to the type for men or women (step S304).
If the control unit 10 determines that the corresponding sewing pattern data exists (step S304; Yes), the sewing pattern data hit by the search is stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data number (step S305). The search process for the sewing pattern data relating to the selection of women is completed.
On the other hand, when the control unit 10 determines that the corresponding sewing pattern data does not exist (step S304; No), the control unit 10 sets a no pattern flag (step S306), and sets the sewing pattern data regarding gentleman / woman selection. The search process ends.

  Thus, the search process for searching for the sewing pattern data is performed so as to correspond to the gentleman / woman search items.

Next, the size search process in step S203 will be described based on the flowchart shown in FIG.
The control unit 10 determines whether or not size data is input through the size data input key 5 on the search item setting screen (see FIG. 6) displayed on the operation panel 16 and the size search is selected (step). S401)
When the control unit 10 determines that the size search selection has not been made (step S401; No), the control unit 10 cancels the processing related to the size selection, re-searches the sewing pattern data under the previous conditions, and performs the search. The results are stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data numbers (step S402), and the search processing of the sewing pattern data relating to size selection is completed.
On the other hand, when the control unit 10 determines that the size search has been selected (step S401; Yes), the control unit 10 searches for sewing pattern data corresponding to the selected size based on the input size data (step S403). ).

Next, the control unit 10 determines whether there is sewing pattern data corresponding to the size as a result of the search (step S404).
When the control unit 10 determines that corresponding sewing pattern data exists (step S404; Yes), the sewing pattern data hit by the search is stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data number (step S405), and the size is selected. The search processing of the sewing pattern data regarding is finished.
On the other hand, when the control unit 10 determines that the corresponding sewing pattern data does not exist (step S404; No), the control unit 10 sets a no pattern flag (step S406), and searches for sewing pattern data related to size selection. Exit.

  Thus, the search process for searching for the sewing pattern data is performed so as to correspond to the size search item.

Next, step number search processing in step S204 will be described based on the flowchart shown in FIG.
The control unit 10 receives the sewing step number data from the sewing step number data input key 6 on the search item setting screen (see FIG. 6) displayed on the operation panel 16 and determines whether or not the step number search is selected. Is determined (step S501).
If the control unit 10 determines that the step number search selection has not been made (step S501; No), the control unit 10 cancels the process related to the step number selection, and re-searches the sewing pattern data under the conditions up to that point, The search results are stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data numbers (step S502), and the search processing of the sewing pattern data related to the step number selection is completed.
On the other hand, when the control unit 10 determines that the step number search selection has been made (step S501; Yes), the control unit 10 searches for the sewing pattern data corresponding to the selected step number based on the input sewing step number data. (Step S503).

Next, the control unit 10 determines whether there is sewing pattern data corresponding to the number of steps as a result of the search (step S504).
When the control unit 10 determines that the corresponding sewing pattern data exists (step S504; Yes), the sewing pattern data hit by the search is stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data number (step S505), and the number of steps. The search process for the sewing pattern data related to the selection ends.
On the other hand, when the control unit 10 determines that the corresponding sewing pattern data does not exist (step S504; No), the control unit 10 sets a no pattern flag (step S506), and searches for the sewing pattern data related to the step number selection. The process ends.

  Thus, a search process for searching the sewing pattern data is performed so as to correspond to the step number search item.

Next, the name search process in step S205 will be described based on the flowchart shown in FIG.
The control unit 10 determines whether or not the selection key 3a of the pattern name data input key 3 on the search item setting screen (see FIG. 6) displayed on the operation panel 16 has been pressed (step S601).
If the control unit 10 does not detect a pressing signal indicating that the selection key 3a of the pattern name data input key 3 is pressed and determines that the selection key 3a is not pressed (step S601; No), the control unit 10 determines the number of characters. The variable m is set to “1” (step S602), and the process proceeds to step S604.
On the other hand, when the control unit 10 detects a pressing signal indicating that the selection key 3a of the pattern name data input key 3 is pressed and determines that the selection key 3a is pressed (step S601; Yes), the control unit 10 performs FIG. A character input screen for inputting the pattern name data shown in FIG. In the character input screen, a process of registering a character string made up of characters and symbols input via the character input key 7 as a character string related to pattern name data (a process of storing a character string related to pattern name data in the EEPROM 10d) ) (Step S603), and the process proceeds to step S602.
In the character input screen shown in FIG. 7, a character string “KAMA-” corresponding to the pattern name data is input and registered.

In step S604, the control unit 10 determines whether or not a character string related to the pattern name data is registered (whether or not a name search is selected) (step S604).
When the control unit 10 determines that the character string related to the pattern name data is not registered in the EEPROM 10d (step S604; No), the control unit 10 cancels the processing related to the name search selection and sets the sewing pattern data as the previous condition. Then, the search result is stored again in the memory M2 of the EEPROM 10d in the order of the sewing pattern data number (step S605), and the search processing of the sewing pattern data related to the name selection is completed.
On the other hand, when the control unit 10 determines that the character string related to the pattern name data is stored and registered in the EEPROM 10d (step S604; Yes), the control unit 10 determines m characters of the character string of the registered pattern name data. The corresponding sewing pattern data is searched so as to coincide with the eye (character number variable m) (step S606).
For example, when the number-of-characters variable is m = 1, the sewing pattern data having the pattern name data whose first character is “K” is the same as the first character of the registered character string “KAMA-”. It is searched whether it is stored in the ROM 10b or the like.

Next, as a result of the search, the control unit 10 determines whether there is sewing pattern data having pattern name data that matches the m-th character (character number variable m) of the character string of the registered pattern name data. (Step S607).
When the control unit 10 determines that there is matching sewing pattern data (step S607; Yes), the control unit 10 determines that the number of patterns of the sewing pattern data determined to exist is a predetermined number of patterns (in the present embodiment). It is determined whether there are more than 4 patterns, the number of patterns that can be displayed in the 4-split display area on the selection screen (step S608).
Then, when the control unit 10 determines that the number of existing sewing pattern data patterns is smaller than the predetermined number of patterns (four patterns in the present embodiment) (step S608; No), the process proceeds to step S611.
On the other hand, when the control unit 10 determines that the number of patterns of the existing sewing pattern data is greater than the predetermined number of patterns (four patterns in the present embodiment) (step S608; Yes), the character number variable m is set to “m = m + 1 "is incremented by +1 (step S609), and the process returns to step S606.

For example, when the character number variable is m = 2, it is searched whether sewing pattern data having pattern name data starting with two characters “KA” is stored in the ROM 10b or the like. Similarly, sewing pattern data having pattern name data beginning with “KAM” if m = 3, “KAMA” if m = 4, and “KAMA−” if m = 5 is stored in the ROM 10b or the like. Or search. In this way, the sewing pattern data is narrowed down to 4 or less, which is the number of patterns that can be displayed in the 4-split display area on the selection screen.
Then, for example, four sewing pattern data of “05; KAMA-AH28”, “09; KAMA-RS56”, “21; KAMA-TX33”, and “33; KAMA-W1-5” are narrowed down. In step S611, these four sewing pattern data are stored in the memory M2 of the EEPROM 10d.

On the other hand, when the control unit 10 determines that there is no matching sewing pattern data (step S607; No), the control unit 10 determines whether there is matching sewing pattern data in the search result in the previous routine. Judgment is made (step S610).
When the control unit 10 determines that there is matching sewing pattern data (step S610; Yes), the process proceeds to step S611.

In step S611, the sewing pattern data hit by the search is stored in the memory M2 of the EEPROM 10d in the order of the sewing pattern data numbers (step S611), and the search processing of the sewing pattern data related to the name selection is completed.
On the other hand, when the control unit 10 determines that there is no matching sewing pattern data (step S610; No), the control unit 10 sets a no pattern flag (step S612), and searches for sewing pattern data related to name selection. Exit.

  Thus, a search process for searching for the sewing pattern data is performed so as to correspond to the pattern name search item.

Then, the differential feed sewing machine 1 is hit by the search, and the sewing pattern data stored in the memory M2 of the EEPROM 10d is displayed in a predetermined order (for example, the order of the sewing pattern data numbers) as shown in the selection screen in FIG. A list is displayed in the quadrant display area of the operation panel 16 (see step S109).
In the selection screen (see FIG. 9), when the display area corresponding to the sewing pattern data “05; KAMA-AH28” is pressed as shown in FIG. 10, the sewing pattern data is displayed as shown in FIG. An editing screen of “05; KAMA-AH28” is displayed on the operation panel 16 (see step S111).
In the differential feed sewing machine 1, the sewing pattern “05; KAMA-AH28” is selected and set.

  As described above, the differential feed sewing machine 1 according to the present invention includes the character string relating to the pattern name data input via the pattern name data input key 3 displayed on the operation panel 16 and the distinction data input key 4. The ROM 10b is based on the gentleman / woman distinction data input, the size data input via the size data input key 5, the sewing step number data input via the sewing step number data input key 6, and the like. The sewing pattern data corresponding to the data can be specified and selected from a plurality of sewing pattern data stored in

In particular, the pattern name data has a predetermined meaning so that the operator who operates the differential feed sewing machine 1 can easily match the pattern name data with the sewing pattern (sewing pattern data). By assigning each sewing pattern as pattern name data composed of a character string associated with a person name, product name, etc., the operator can easily remember the pattern name data and the sewing pattern data in correspondence with each other. Compared to associating numbers such as pattern numbers that are difficult to remember with sewing pattern data, it is easier to input pattern name data for selecting desired sewing pattern data, and to select sewing pattern data more smoothly. It is easy to be processed.
