Abstract
A sewing machine with thread take-up mechanism is so constructed as to vertically move a take-up member, supported on a needle bar in such a manner as to be vertically movable at a timing which is different from that of the movement of the needle bar on which the take-up member is moved. The take-up member has a hole through which a thread being lead to the sewing needle is inserted.
