A multi-needle type embroidery sewing machine and a computer-readable storage medium including a computer program for the multi-needle type embroidery sewing machine that may enable convenient selection and replacement of thread information. The multi-needle type embroidery sewing machine may include a plurality of needle bars, a needle bar thread information storage device, a needle bar selection device that enables the selection of a suite of needle bars selected from the plurality of needle bars, and a control device for changing needle bar thread information that corresponds to a needle bar in the selected suite of needle bars.

Multi-needle type embroidery sewing machine and computer-readable storage medium including a computer control program for the multi-needle type embroidery sewing machine

A sewing machine of the present disclosure is provided with a sewing device capable of pattern sewing by controlling a needle swinging mechanism that swings a vertically reciprocating needle bar in a horizontal direction and a cloth feeding mechanism having a feed dog, a controller that controls the sewing device and a memory that stores sewing data supplied externally via a data transmitting network or a data storage media. The aforementioned controller determines whether or not the pattern to be sewn based on the sewing data loaded from the memory can be sewn by the sewing device and upon determining that sewing is not possible, the sewing data is modified to a pattern that can be sewn by the sewing device.

Sewing machine and computer program

A control unit for controlling an embroidery sewing machine includes an embroidery-data storing portion, a feed-data extracting portion, and a thread-cutting-data adding portion. The embroidery-data storing portion stores embroidery data defining an embroidery pattern sewn by a sewing portion and a workpiece feeding portion. The embroidery data includes stitch data indicating needle drop positions for forming stitches on a workpiece and feed data indicating feed positions for feeding the workpiece. The feed-data extracting portion extracts the feed data from the embroidery data read from the embroidery-data storing portion. The thread-cutting-data adding portion adds thread cutting data immediately prior to the feed data extracted by the feed-data extracting portion. The thread cutting data instructs a thread cutting portion to perform thread cutting.

Control unit for controlling embroidery sewing machine

A sewing apparatus such as a sewing machine includes a cassette mount to which a thread cassette having a thread accommodating section for accommodating a thread supply is detachably attached, at least one detector detecting an operating state of at least one mechanism related with the thread cassette, a determining unit determining whether the thread cassette can be attached to the cassette mount, based on a result of detection by the detector, and an informing unit informing a result of determination by the determining unit.

Sewing apparatus and informing control program therefor

A sewing apparatus such as sewing machine includes a needle bar, a needle bar rocking mechanism for rocking the needle bar, a thread cassette having a thread accommodating section for accommodating a thread, a cassette mount to which the thread cassette is detachably attached, a threading mechanism for passing the thread drawn from the thread cassette through a hole of a sewing needle mounted on the needle bard, a detector for detecting the thread cassette ejected from the cassette mount, and a needle bar position control unit controlling the needle bar rocking mechanism so that the needle bar is rocked so as to occupy a predetermined zigzag position, when the detector has detected the thread cassette ejected from the cassette mount.

Sewing apparatus and needle bar position control program therefor

A sewing machine includes a thread cassette having a thread accommodating cavity in which a supply of thread is accommodated, a cassette mount to which the thread cassette is detachably attached, a thread tensioner adjusting a tension of the thread drawn from the thread cassette, a detachment operating member operated so that the thread cassette is detached from the cassette mount, and a thread tension control controlling the thread tensioner so that the thread is set at a predetermined tension when the detachment operating member has been operated.

Sewing machine with thread tension control function and thread tension control program therefor

A sewing apparatus such as a household sewing machine includes a needle bar, a needle bar vertically moving mechanism, a needle bar position changing operation unit operated via the needle bar vertically moving mechanism to change a vertical position of the needle bar, a thread cassette having a thread accommodating section accommodating a supply of thread, a cassette mount to which the thread cassette is detachably attached, a cassette detector detecting the thread cassette attached to the cassette mount, and a needle bar position changing control unit controlling the needle bar vertically moving mechanism so that in a case where the needle bar position changing unit has been operated, the needle bar is changed from an upper stop position to a lower stop position or vice versa according to a position of the needle bar at the time of operation of the needle bar position changing unit when the thread cassette is attached to the cassette mount according to a result of detection by the cassette detector, the needle bar position changing control unit further controlling the needle bar vertically moving mechanism so that the needle bar is changed to the upper stop position irrespective of the position of the needle bar at the time of operation of the needle bar position changing unit when the thread cassette is unattached to the cassette mount according to the result of detection by the cassette detector.

Sewing apparatus with needle bar position changing control

A sewing apparatus such as a household sewing machine includes a needle bar on which a sewing needle is mounted, a needle bar vertically moving mechanism vertically moving the needle bar, a thread cassette having a thread accommodating section accommodating a supply of thread, a cassette mount to which the thread cassette is detachably attached, a threading mechanism operated in synchronization with attachment of the thread cassette to the cassette mount when the needle bar is stopped at a predetermined position, the threading mechanism passing the thread drawn from the thread cassette through an eye of the needle mounted on the needle bar, and a threading limiting unit limiting the threading mechanism so that the threading mechanism is inoperative in a case where the thread cassette is attached to the cassette mount when the apparatus is disconnected from a power supply.
