Abstract
A sewing data forming device for sewing machines comprising a coordinate input unit for inputting a coordinate value and a plurality of switches for providing instructions at an operating step, and forming needle position data for the sewing machine by calculating coordinate values sequentially inputted from said coordinate input unit. When needle position data to be newly inputted is within a predetermined distance from previously inputted needle position data, the needle position data to be newly inputted is replaced, when inputted, by the previously inputted needle position data as the same data. Also, a method of forming sewing data for a sewing machine is performed using the above device.
Claims15
A method of forming sewing data for a sewing machine, comprising the steps of:
- succesively reading coordinates data from a coordinates input device;
- calculating a first needle position data according to said coordinates data;
- and
- if said first needle position data is within a predetermined range from second needle position data which has previously been input, then replacing said first needle position data by the same data as said second needle position data.
A method of forming sewing data for a sewing machine, the method comprising the steps of:
- succesively reading coordinates data from a coordinates input device;
- calculating a first needle position data according to said coordinates data;
- generating a same-position selecting instruction;
- detecting whether said first needle position data is within a predetermined range from second needle position data which has previously been input;
- and
- replacing said first needle position data by the same data as said second needle position data in response to detection of both of said same point selecting instruction and said first needle position data being within said predetermined range.
A device for forming sewing data for a sewing device, comprising:
- coordinates input means for inputting coordinate values of a needle position;
- operation means for controlling the coordinate values successively inputted from said coordinates input means to obtain first needle position data for a sewing machine;
- detection means for detecting whether said first needle position data input is within a predetermined range from second needle position data which has been already inputted and
- conversion means for replacing said first needle position data by said second needle position data when it is detected by said detection means that said first needle position data is within said predetermined range.
