Claims

[Scope of utility model registration request]

A control device that outputs stitch information corresponding to the displacement of a stitch forming mechanism having a needle bar and a feed dog, and a fabric thickness that corresponds to the position from the top of the bed of a presser foot placed above the bed facing the feed dog. A cloth thickness detection device that outputs information; a thread amount calculation device that calculates the amount of thread required to form one stitch from the stitch information and cloth thickness information and outputs the thread amount information; Each time, the receiver feeds out the corresponding amount of yarn from the supply source and supplies it to the thread take-up, and the feed dog is in an operating state in which it moves four times, moving in and out from the top of the bed, and in an inactive state in which it is always recessed below the bed. In a sewing machine equipped with a switchable feed dog sinking device, a position detecting device that detects a specific rotation angle of the main shaft corresponding to the highest and lowest timing of the feed dog and generates different position signals; A discrimination device that compares fabric thickness information at the time when the signal is generated and generates different discrimination signals depending on whether the two fabric thickness information is the same, and different modes that respond to the operating/inoperative state of the feed dog in response to different discrimination signals. A feed mode display device for a sewing machine, comprising a display device for displaying.
