A processing data generation device includes a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring processing of acquiring a pattern represented by a contour, division processing of dividing the pattern into a plurality of pattern pieces, and offset setting processing of setting an offset line disposed at a position separated to an outside, from an adjacent portion, by a predetermined distance. The processes include processing line setting processing of setting, for each of the plurality of pattern pieces, a processing line including the offset line and surrounding a pattern piece and processing line processing of generating processing line processing data, for each of the plurality of pattern pieces, for processing a sheet-shaped workpiece along the processing line, using a processing device configured to perform processing on the workpiece.

Processing data generation device, non-transitory computer-readable medium, and sewing machine

A sewing machine includes a holder, a movement portion, a needle bar, a sewing portion, an input portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring embroidery data, associating, for each of a plural pieces of pattern data included in the embroidery data, a sewing position with the pattern data, stopping sewing when partition data included in the embroidery data is read out. The processes include driving, when a sewing start command is received during a stop period, the movement portion and the sewing portion in accordance with a next piece of pattern data and the sewing position, receiving a change command during the stop period, and changing the sewing position associated with target pattern data in accordance with the received change command.

A container includes a cover body and a holding body, and is removably mounted on a needle plate of a sewing machine including a horizontal shuttle. The horizontal shuttle includes an inner shuttle that includes a bobbin containing portion. The cover body is plate-shaped, is removably mounted in the needle plate in a position above the horizontal shuttle, and includes a through-hole and a first face that occupies the same plane as a top face of the needle plate when the cover body is mounted in the needle plate. The holding body is disposed inside the bobbin containing portion and includes a side wall and a bottom wall. The side wall encircles an area of a second face in which the through-hole is formed. The second face is a face on the opposite side of the cover body from the first face. The bottom wall is opposite the second face.

Container and sewing machine provided with the container

An embroidery frame includes a mounting portion, an annular portion, a rotation member, a first guide portion, an extending portion, and a drive mechanism. The mounting portion is mounted on a carriage of a sewing machine. The annular portion holds a work cloth. The rotation member is formed in an annular shape and is supported by the annular portion. The rotation member rotates in a circumference direction of the annular portion. The first guide portion is provided on the rotation member and has a first penetrating portion. A through hole is formed in the first penetrating portion. A string-like material to be supplied for sewing is inserted through the first penetrating portion. The extending portion is formed on the annular portion and extends toward the outside in a radial direction of the annular portion. The drive mechanism is provided on the extending portion and rotates the rotation member.

A sewing machine includes a bed, a needle plate, a needle bar, a needle bar swing mechanism, a lift mechanism, an optical detecting portion, and a control portion. The lift mechanism is configured to raise and lower a presser foot. The optical detecting portion is configured to optically detect a cord guided by the guide portion, and to output data representing the cord. The control portion is configured to calculate a width of the cord based on the data output by the optical detecting portion, calculate a height position of the presser foot based on the width of the cord, and cause the lift mechanism to move the presser foot to the height position.

A sewing machine includes a bed, a needle plate, a needle bar, a needle bar swing mechanism, an optical detecting portion, and a control portion. The optical detecting portion is configured to optically detect a cord pressed by a presser foot, and to output data representing the cord. The control portion is configured to calculate a width of the cord based on the data output by the optical detecting portion, calculate a swing width of the needle bar based on the width of the cord, and cause the needle bar swing mechanism to swing the needle bar with the swing width.

A sewing machine may comprise a needle bar driving mechanism, a cutting needle rotation mechanism, and an embroidery frame movement mechanism configured to move an embroidery frame comprising a protruding portion. A cam member may be fixed to the needle bar and comprise a plurality of cams. A processor of the sewing machine may set a height of the needle bar to a specific position from a plurality of positions. Each of the plurality of positions may represent that each of the plurality of cams is able to contact with the protruding portion. The processor may instruct the needle bar driving mechanism to move the needle bar to the specific position and instruct the embroidery frame movement mechanism to move the embroidery frame to a position where the protruding portion is able to contact with one of the plurality of cams.

A compact rotation output device is realized by disposing an output shaft of a reduction gear transmission coaxially with an axis line of a rotating disk while simultaneously ensuring a space in a rear face of the rotating disk through which a columnar bar or wiring etc. can pass. A reduction gear transmission is provided with an input shaft having an eccentric rotation member, an external gear that has a through hole at its center and revolves orbitally while engaging with the eccentric rotation member, and an internal gear that surrounds the external gear while meshing with the external gear and allows the orbital revolution of the external gear. The number of teeth of the external gear differs from the number of teeth of the internal gear. The rotating disk is fixed to one of the external gear and the internal gear of the reduction gear transmission. The columnar bar is formed on the rotating disk, this columnar bar rotating together with the rotating disk, passing through the external gear, and extending longer than the input shaft.

Rotation output device

To facilitate an integrating operation and to make fabricating cost inexpensive. An idle gear for transmitting rotation of an input gear of a drive motor to a cylindrical gear is rotatably supported by an input side end portion of a specific one crank pin, and therefore, the idle gear may simply be supported by the crank pin, further, a length in an axial direction of the cylindrical gear brought in mesh with both of the idle gear the input gear is sufficiently to a degree of being more or less longer than a distance between remote side ends of the two gears.
