The present invention provides a sewing machine for identifying the embroidery frame correctly by using the existing mechanism and embroidery frame. A photography unit photographs an attached embroidery frame from a height direction, an embroidery frame transfer unit moves the embroidery frame from a specific location within a region surrounded by the embroidery frame until the photography unit photographs an image of the embroidery frame corresponding to one of the plurality of embroidery frame images registered in the database, a calculation unit calculates a size of the embroidery frame based on a moving distance of the embroidery frame moved by the embroidery frame transfer unit, and an embroidery frame identification unit identifies the embroidery frame based on the size of the calculated embroidery frame.

Sewing machine, method for determining embroidery frame and program

Sewing machine provided with an indication device including a display that is so large that the lower leftward portion protrudes into the stitch working area of the machine. The display may be moved up and down by of a switch and may be moved up until the lower end side of the display aligns with the lower end side of the machine arm and may be stopped at an upper optional position. At the lowest position, the upper end side of display has the upper side located in alignment with the top side of machine body and has the front side plane planar with the front side of the arm and has the lateral end side planar with the lateral end side of the machine body. The display has no part protruding from the machine body at the lowest position, and is thus placed compactly in the machine frame of machine body.

Sewing machine provided with indication device

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 switchwhich is rotated by a pattern selecting dialand has a plurality of switches Sw arranged in coaxial circles, a plurality of projectionsarranged in coaxial circles, and an electronic indicator. A pattern is optionally selected by the projectionsand switches Sw which are turned on in optional combination by rotation of the mode switch, and the selected pattern is indicated at the electronic indicator

Sewing machine

Marks such as patterns, designs, numbers, or the like are cut out of a mark sheet or mark sheets placed on a glass base by a thermal cutter having a heated cutting bit. The thermal cutter is movable two-dimensionally over the mark sheet, and is also vertically movable between an upper position in which the thermal cutter is lifted off the mark sheet supported on the base and a lower position in which the thermal cutter is lowered in contact with the mark sheet supported on the base. The thermal cutter is angularly movably supported on an eccentric shaft that is rotatable by a stepping motor. The thermal cutter has a cutting bit resiliently urged by a spring for stable positioning. A range or ranges in which desired marks are to be cut out of a mark sheet or mark sheets can be confirmed by being traced by the thermal cutter before the marks are actually cut out. When mark numerals indicative of desired numbers are to be cut out, such mark numerals are rearranged and displayed for the operator's information. The thermal cutter can be cleaned by a cutter cleaner in a different cleaning pattern each time the thermal cutter has moved a predetermined distance in contact with the mark sheet or mark sheets. The thermal cutter moves to the cutter cleaner and also to a position to start cutting out desired marks, at a higher speed than the speed at which it cuts out the desired marks.
