A multi-needle sewing machine includes a plurality of needle bars, a needle plate, a needle bar case, a needle bar drive mechanism, a needle bar case movement mechanism, a mounting portion, a frame movement mechanism, 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 identification processing of identifying a position of the needle bar case in the arrangement direction, in accordance with detection of a retraction command causing the mounting portion to be moved to a retracted position, setting processing of setting the retracted position of the mounting portion on the basis of the identified position of the needle bar case in the arrangement direction, and movement processing of controlling the frame movement mechanism to move the mounting portion to the set retracted position.

Multi-needle sewing machine

A sewing machine acquires a selected pattern that is selected from among a plurality of embroidery patterns. The sewing machine displays a pattern image representing the selected pattern. The sewing machine identifies a specified position indicated by the instruction. The sewing machine determines, when the selected pattern is acquired a plurality of times, whether one of a plurality of the pattern images is displayed at the identified specified position. When it is determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which the pattern image is displayed at the specified position as the editing target. When it is not determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which a mask region encompassing the selected pattern is set at the specified position as the editing target.

Sewing machine and non-transitory computer-readable medium

A sewing machine includes at least one needle bar, a threading motor, a threading mechanism, a processor, and a memory. The threading mechanism is configured to pass an upper thread through an eye of a sewing needle. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include making one of a setting that prohibits operation of the threading mechanism and a setting that does not prohibit the operation of the threading mechanism. The processes include switching the operation of the threading mechanism by prohibiting the operation of the threading mechanism in a case where the setting that prohibits the operation of the threading mechanism is made, and permitting the operation of the threading mechanism in a case where the setting that does not prohibit the operation of the threading mechanism is made.

A sewing machine includes needle bars, a notification 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 sewing data for sewing an embroidery pattern made up of a plurality of partial pattern, setting correspondences between a needle bar among the needle bars and an upper thread data set included in the sewing data, for each of the needle bars, and the sewing embroidery pattern, detecting an error that occurs during the sewing, stopping the sewing when the error is detected, specifying a change-eligible needle bar, for which the sewing is completed, when a target data set exists, the correspondence with one of the needle bars not being set for the target data set, and causing the notification portion to notify information indicating the specified change-eligible needle bar.
