With a overlock sewing machine, when a switching mechanism is switched to a threading-enabled state, and a looper cover is closed, the looper cover is slid toward one side in the hinge shaft axial direction so as to operate a detection lever. In the non-operating state, the detection lever is set to an initial position where it does not press an operation protrusion of a switch. When a side cover is closed, and the detection lever is operated, the operation lever is set to an operation-enabled position where it presses the operation protrusion. When the operation lever is operated, and the side cover is opened, the detection lever is set by passing through the operation-enabled to the operation-disabled position where it does not press the operation protrusion.
A sewing-machine operating program is installed in a terminal device of a user. A specifying information acquiring step causes a short-distance information acquiring unit to acquire specifying information recorded on a sewing-machine main unit. In the distance measuring step, an apart distance is calculated from a detection result of a movement detecting sensor with a position where the specifying information is acquired being as an initial position. In the distance comparing step, for a remote operation to the sewing-machine main unit, the apart distance and a prescribed distance are compared. In the function restricting step, when the apart distance is within the prescribed distance, an operation command is transmitted to the sewing-machine main unit via a wireless communication device, and when the apart distance exceeds the prescribed distance, the operation command is not transmitted to the sewing-machine main unit.

When marks all align with a mark alignment region in an image, an image is acquired for an embroidery frame and embroidery design sewn to a portion of a cloth mounted on the frame. Image analysis is performed based on correspondence between acquired information for the embroidery frame and for the marks. The embroidery region of the embroidery frame is determined based on analysis results. Acquired images of the cloth having the embroidery design portion and an embroidery design to be sewn to it are displayed. The embroidery design image to be sewn is edited to connect it to the image of the embroidery design already sewn to the portion in the displayed image. This prevents the occurrence of overlapping or gaps between embroidery design units even if accumulated shrinkage occurs in sewing, or slight alignment errors occur in position or rotation when cloth is mounted on the embroidery frame.
A sewing data generating unit acquires embroidery frame information and a mark alignment region displayed on a display unit for guiding multiple marks that define an embroidery region of the embroidery frame. When the marks are all positioned within the mark alignment region displayed on the display unit, the sewing data generating apparatus acquires an image of the embroidery frame and a sewing target mounted on a base cloth mounted on the embroidery frame. The sewing data generating apparatus performs image analysis based on a correspondence between the acquired information with respect to the embroidery frame and the marks in the acquired image, so as to determine the embroidery region of the embroidery frame. The sewing data generating apparatus generates outline data for the sewing target based on the determined embroidery region. This allows an applique to be sewn at an accurate position without a need to prepare dedicated data.
