Electronically controlled pattern sewing machine for automatically detecting and programming coordinate of sewing object and method for controlling the same

An electronically controlled pattern sewing machine comprising:

• a jig disposed thereon to support a fabric thereagainst and having a pattern-shaped through hole formed thereon;
• a marker to mark a sewing line along a periphery of the pattern-shaped through hole of the jig;
• a sensor coupled to one side thereof to sense coordinates of the sewing line marked by the marker;
• a memory to store the coordinates sensed by the sensor;
• a controller to automatically convert the coordinates stored in the memory into sewing coordinates for the electronically controlled pattern sewing machine;
• a function setting part to set sewing functions on the sewing coordinates converted by the controller;
• and
• an operation panel box configured to operate the electronically controlled pattern sewing machine to perform a sewing operation according to the sewing coordinates converted by the controller and the sewing functions set by the function setting part.

A method for controlling an electronically controlled pattern sewing machine, comprising steps of:

• clamping a jig onto the electronically controlled pattern sewing machine to pressurize a fabric thereagainst;
• marking a sewing line along a periphery of a pattern-shaped through hole formed on the jig;
• sensing coordinates of the sewing line by a sensor;
• storing the sensed coordinates in a memory;
• converting the coordinates stored in the memory into sewing coordinates for the electronically controlled pattern sewing machine by a controller;
• setting sewing functions on the converted sewing coordinates by a function setting part;
• and
• operating, by an operation panel box, the electronically controlled pattern sewing machine to perform a sewing operation according to the sewing coordinates converted by the controller and the sewing functions set by the function setting part.
