摘要： The sewing system includes a device and a sewing machine including a movement mechanism to move an embroidery frame. The device identifies reference point coordinates representing a position of a reference point provided in a range prescribed by an inner frame of the embroidery frame and transmits the reference point coordinates to the sewing machine. The sewing machine notifies a notification position, using a notification portion, with respect to the range prescribed by the inner frame and acquires a relative movement amount of the embroidery frame with respect to the notification portion, for aligning the notification position and the reference point provided in the range prescribed by the inner frame. The sewing machine decides, on the basis of a relationship between the movement amount and the reference point coordinates, a deviation from a prescribed state of a positional relationship between the inner frame and the movement mechanism.

摘要： A software activation system includes a sewing machine and at least one server connected via a network. The sewing machine acquires an authentication code corresponding to an activation target software that is at least one of a program and data not activated on the sewing machine, and transmits, to an authentication server included in the at least one server, an authentication request including the acquired authentication code. The server acquires an authentication key on the basis of the authentication request, when the authentication request is received by the first receiver; and transmits the acquired authentication key to the sewing machine. The sewing machine also receives the authentication key from the authentication server, determines whether the received authentication key satisfies a predetermined authentication condition, and activates the activation target software on the sewing machine when it is determined that the authentication key satisfies the predetermined condition.

摘要： An embroidery frame includes a first frame and a second frame. The second frame holds an object to be sewn with the first frame. The second frame includes a first member and a second member. The first member includes a plurality of magnets and an annular portion. The annular portion is made of magnetic material. The first member is able to be switched to one of a first position and a second position. The second member includes a plurality of plate members. The plurality of plate members are made of magnetic material. The first position is a position where some of the plurality of magnets faces the gap and a portion of two of the plate members that are adjacent across the gap. The second position is a position where some of the plurality of magnets faces a corresponding one of the plurality of plate members.
