Sewing machine
Disclosed is a sewing machine having a pattern selecting device including a pattern selecting dial and an electronic indicator for indicating a pattern selected by the pattern selecting device. More particularly, the pattern selecting device includes a mode switch 2 which is rotated by a pattern selecting dial 5 and has a plurality of switches Sw arranged in coaxial circles, a plurality of projections 2 c arranged in coaxial circles, and an electronic indicator 10 . A pattern is optionally selected by the projections 2 c and switches Sw which are turned on in optional combination by rotation of the mode switch 2 , and the selected pattern is indicated at the electronic indicator 10.
1. A sewing machine having a dial provided therewith to be operated to select patterns to be stitched, said sewing machine comprising:
a signal producing means which is activated in association with operation of said dial to produce a code signal for a selected pattern;
a pattern indicating means which is activated in response to said code signal to indicate the selected pattern thereat; wherein said signal producing means includes a plurality of switches arranged in circles coaxial with said dial, said switches being turned on and off to produce said code signal as said dial is rotated.
2. The sewing machine as defined in claim 1 , wherein said plurality of switches include the switches arranged in an outermost circle in number corresponding to the number of patterns which may be selected, said number of switches being turned on to make effective the code signal which is produced by the switches of the other coaxial circles which are turned on and off.
3. The sewing machine as defined in claim 1 , wherein said plurality of switches are operated to turn on and off by a plurality of projections which are arranged in circle coaxial with said dial on the rear side thereof.
4. A sewing machine as defined in claim 1 further comprising:
a pattern selecting mechanism which is operated in association with operation of said dial to select one of a plurality of patterns;
said pattern indicating means which is activated in response to said code signal indicates the pattern selected by said pattern selecting mechanism.
5. The sewing machine as defined in claim 1 further comprising:
a means which is activated in response to said code signal to supply the pattern data designated by said code signal;
a pattern stitching mechanism which is operated in response to said pattern data to carry out a pattern stitching operation.
6. A sewing machine having a dial provided therewith to be operated to select patterns to be stitched, said sewing machine comprising:
a signal producing means which is activated in association with operation of said dial to produce a code signal for a selected pattern;
a pattern indicating means which is activated in response to said code signal to indicate the selected pattern thereat, wherein the patterns which may be selected are divided in a plurality of groups, said sewing machine further comprising pattern group selecting means for optionally selecting the pattern group, and wherein said dial is operated to optionally select the patterns of a selected pattern group, and wherein said signal producing means produces a cocie signal having a signal added thereto which is corresponding to a selected pattern group.
7. A sewing machine as defined in claim 6 , further comprising:
a pattern selecting mechanism which is operated in association with operation of said dial to select one of a plurality of patterns;
wherein said pattern indicating means which is activated in response to said code signal indicates the pattern selected by said pattern selecting mechanism.
8. The sewing machine as defined in claim 6 , further comprising:
a means which is activated in response to said code signal to supply the pattern data designated by said code signal;
a pattern stitching mechanism which is operated in response to said pattern data to carry out a pattern stitching operation.
9. A sewing machine having a dial provided therewith to be operated to select patterns to be stitched, said sewing machine comprising:
a signal producing means which is activated in association with operation of said dial to produce a code signal for a selected pattern;
a pattern indicating means which is activated in response to said code signal to indicate the selected pattern thereat, a feed selecting means which is operated to select a cloth feeding operation which is different than the cloth feeding operation of normal stitching mode, and wherein said signal producing means produces a code signal having a signal added thereto corresponding to the cloth feeding operation selected by said feed selecting means.
10. A sewing machine as defined in claim 9 , further comprising:
a pattern selecting mechanism which is operated in association with operation of said dial to select one of a plurality of patterns;
wherein said pattern indicating means which is activated in response to said code signal indicates the pattern selected by said pattern selecting mechanism.
11. The sewing machine as defined in claim 9 , further comprising:
a means which is activated in response to said code signal to supply the pattern data designated by said code signal;
a pattern stitching mechanism which is operated in response to said pattern data to carry out a pattern stitching operation.
