An embroidery frame driving device includes: a base plate firmly fixed to an X-Y driving unit of the embroidery frame driving device; a fixation arm provided on the base plate; an attachment/detachment cam; a removing link; a coupling link; and an embroidery frame. The embroidery frame is slid against the base plate to rotate the attachment/detachment cam and the fixation arm through pressing of a pressing part of a fixation part to press and fix one end of the fixation arm to a fixation groove of the fixation part in attachment of the embroidery frame. The removing link is operated to rotate the coupling link and the attachment/detachment cam to rotate the fixation arm and release pressing and fixation of the fixation groove of the fixation part by the one end of the fixation arm in detachment of the embroidery frame.

Provided with an embroidery unit attaching and detaching device capable of preventing an embroidery unit from falling from a sewing machine and capable of preventing the damage of a portion connecting the embroidery unit and the sewing machine even when the moment load of twisting the embroidery unit with respect to the sewing machine is applied. An embroidery unit attaching and detaching device includes: a lock mechanism configured to operate in association with a motion of an embroidery unit in an attaching direction to restrict the motion of the embroidery unit in a detaching direction with respect to a sewing machine; and support mechanisms for restricting a relative motion of the sewing machine and the embroidery unit in a vertical direction where recessed portions and protruded portions are engaged with each other.

An embroidery apparatus includes a main unit to be detachably mounted on a bed section of a sewing machine, a first translation mechanism that moves an embroidery frame holder with an embroidery frame mounted thereon in a first direction, a second translation mechanism that moves the first translation mechanism along an upper surface of the main unit in a second direction that orthogonally intersects the first direction, and an elevator mechanism that is supported by the second translation mechanism at opposite sides of the main unit and that raises and lowers the first translation mechanism. The embroidery apparatus is applicable to a sewing machine switchable between embroidery stitching and standard stitching. During standard stitching, the upper surface of the first translation mechanism is flush with the upper surface of the main unit, which enables both upper surfaces to be used as an auxiliary table.

An embroidery frame transport device includes a guide portion, a lever, and a locking portion. The guide portion is configured to prescribe a first direction being a movement direction when the embroidery frame is removed and a second direction being a movement direction when the embroidery frame is mounted. The lever is configured to move between a first restriction position that restricts the movement in the first direction of the embroidery frame and a first release position that does not restrict the movement in the first direction of the embroidery frame. The locking portion is configured to move between a second restriction position that restricts the movement in the second direction of the embroidery frame and a second release position that does not restrict the movement in the second direction of the embroidery frame.

A non-transitory computer-readable medium stores computer-readable instructions for sewing data generation. The computer-readable instructions are executed by a processor provided in a sewing data generation device. When executed by the processor in the sewing data generation device, the computer-readable instructions instruct the processor to perform following processes. First, the processor acquires a pattern. And, the processor divides the acquired pattern into a first pattern and a second pattern. The second pattern includes an overlapping portion. The overlapping portion in the second pattern partially overlaps with the first pattern. The processor generates sewing data to sew each of the first pattern and the second pattern on a sewing object. And, the processor generates processing data to process, in full size, a processing pattern. The processing pattern is obtained by excluding the overlapping portion from the second pattern, on a sheet-like processing object different from the sewing object.
