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

Embroidery sewing machine having a Y-direction drive mechanism including an elongated arm which is normally accommodated in a cutout portion formed at a bed of the machine body and forms a part of that body. The upper side of the arm is continuous with the upper side of the bed in a same plane. The arm has a frame support to which an embroidery frame is removably attached, the frame holding a work to be embroidered. The arm is arranged as turnable to extend from the rear side of the bed into the depth direction (Y-direction) of the machine, where the arm is operative for embroidery stitching. The arm is connected to an X-direction drive mechanism arranged in the machine body and may be moved in the width direction (X-direction) of the machine body, by the X-direction drive mechanism while the embroidery frame is moved in the Y-direction along the arm.

Embroidery sewing machine

A sewing machine with an embroidery stitching function is disclosed, wherein a needle is vertically reciprocated to form stitches on a work held by an embroidering frame (,) which is moved in X-Y directions by a frame moving device relative to the needle on a working surface (,) of a working bed (,), the frame moving device being composed of composed of a first mechanism (A) for moving said embroidering frame in the Y direction and a second mechanism (B) for moving the embroidering frame in the X direction, the first mechanism (A) being located on the working surface and connected to the embroidering frame (,) and the second mechanism (B) being housed in the sewing machine, the first mechanism (A) being moved by the second mechanism (B) to one end of the working bed (,) where the first mechanism (A) is rotated to a retreated position at the time of carrying out the ordinary stitching operation.

A lock stitch sewing machine with an automatic thread tension adjusting device is disclosed, wherein the sewing machine has a plurality of thread tension adjusting mechanisms 7, each of which including a pair of thread tension disks 12, 13, one of which is normally pressed by a spring toward the other. A sensor 4 is responsive to the operation of a thread tension releasing lever 20 made by a user with a slight touch applied thereto to give a signal. A CPU1 is responsive to the signal to compare the value of the existing thread tension of the thread tension adjusting mechanisms 7 with a predetermined one. If the value of the existing thread tension is higher than the predetermined one, the CPU1 is operated reduce the value of the existing thread tension to a predetermined one. Thus the tension releasing operation ability is increased.
