The present invention provides a sewing machine that enables to switch frequently used functions during the sewing work with good usability, validate only the indicator related to the work among a plurality of indicators, and enables GUI operations by a screen display unit. Thus, high operability can be achieved. The sewing machine includes: a setting unit for setting operation buttons related to desired sewing work; an operation display unit for displaying the operation buttons set by the setting unit, the operation display being arranged at an arm part; and a screen display unit arranged at a position different from the operation display unit.

A sewing machine includes at least: a movement detection unit for detecting a movement amount of a material to be sewn; a drive motor for operating a needle; a control unit for operating the drive motor; and a storage unit. The storage unit stores a sewing speed and a sewing pitch. The control unit is configured to implement a first control mode and a second control mode. In the first control mode, the control unit operates the drive motor at the stored sewing speed when the detected value by the movement detection unit exceeds a predetermined first threshold. In the second control mode, the control unit operates the drive motor such that the sewing is carried out at the stored sewing pitch on the basis of the detected value when the detected value exceeds a predetermined second threshold. These first control mode and second control mode are switchable.

A method for identifying reference points in a hand drawing track with a number (n) of dots includes marking a first one of the dots as a reference point; for each of a (k.sup.th) one of the dots, determining an included angle; marking the (k.sup.th) one of the dots as a reference point when the included angle associated therewith is larger than a predetermined angle; calculating an accumulated distance between the (k.sup.th) one of the dots and a last one of the reference point (s) thus marked when the included angle is not larger than the predetermined angle; and marking the (k.sup.th) one of the dots as a reference point when it is determined that the accumulated distance thus calculated is larger than the predetermined distance, 2k(n1).

The present invention relates to a quilting machine, or stitcher, further including a centrally located swiveling tablet mount for securing a tablet that is used in the quilting process. The mount is positioned such that a user may access the mount from either side of, or the rear or front of the stitcher. The mount is one capable of swiveling so that the user does not have to move the tablet between front and rear mounts of the stitcher or buy separate tablets for a front and rear mount.
