A sewing machine comprising:
- a thread cassette having a thread accommodating cavity in which a supply of thread is stored;
- 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.
A sewing machine comprising:
- a thread cassette having a thread accommodating cavity in which a supply of thread is stored;
- 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 cassette detector detecting the thread cassette having been attached to the cassette mount;
- and
- a thread tension control controlling the thread tensioner so that the thread is tensioned a predetermined period of time after detection of the thread cassette by the cassette detector.
A thread tension control program executed by a computer provided for a sewing machine, accomplishing the functions of:
- controlling a thread tensioner adjusting a tension of the thread drawn from a thread cassette having a thread accommodating cavity in which a supply of thread is accommodated when the thread cassette is attached to or detached from a cassette mount of the sewing machine;
- and
- controlling the thread tensioner so that the thread is set at a predetermined tension when a detachment operator has been operated, the detachment operator being operated so that the thread cassette is detached from the cassette mount.
