Abstract
A sewing apparatus such as sewing machine includes a needle bar, a needle bar rocking mechanism for rocking the needle bar, a thread cassette having a thread accommodating section for accommodating a thread, a cassette mount to which the thread cassette is detachably attached, a threading mechanism for passing the thread drawn from the thread cassette through a hole of a sewing needle mounted on the needle bard, a detector for detecting the thread cassette ejected from the cassette mount, and a needle bar position control unit controlling the needle bar rocking mechanism so that the needle bar is rocked so as to occupy a predetermined zigzag position, when the detector has detected the thread cassette ejected from the cassette mount.

A sewing apparatus comprising:
- a needle bar;
- a needle bar rocking mechanism for rocking the needle bar;
- a thread cassette having a thread accommodating section for accommodating a thread;
- a cassette mount to which the thread cassette is detachably attached;
- a threading mechanism for passing the thread drawn from the thread cassette through a hole of a sewing needle mounted on the needle bar;
- a detector for detecting the thread cassette ejected from the cassette mount;
- and
- a needle bar position control unit controlling the needle bar rocking mechanism so that the needle bar is rocked so as to occupy a predetermined zigzag position, when the detector has detected the thread cassette ejected from the cassette mount.
A needle bar position control program for controlling a position of a needle bar in a sewing apparatus including a needle bar, a needle bar rocking mechanism for rocking the needle bar, a thread cassette having a thread accommodating section for accommodating a thread, a cassette mount to which the thread cassette is detachably attached, a threading mechanism for passing the thread drawn from the thread cassette through a hole of a sewing needle mounted on the needle bar, and a detector for detecting the thread cassette ejected from the cassette mount, the program accomplishing a function of controlling the needle bar rocking mechanism so that the needle bar is rocked so as to occupy a predetermined zigzag position, when the detector has detected the thread cassette ejected from the cassette mount.
