Title: Sewing system
Inventor: TOMITA SHINTARO
IPC: D05B39/00
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a button holing sewing machine which can form a button hole with good appearance to appeal higher class feeling. SOLUTION: When a embroidery pattern is designated, the kinds of usable embroidery frame for sewing the designated embroidery pattern are displayed by figures in a frame display area 72. The kind of an embroidery frame actually set on a carriage is discriminated. When the actually set embroidery frame cannot be used for sewing the designated embroidery pattern, a notice message is displayed. Because an embroidery frame usable for the designated pattern is displayed and whether the actually set embroidery frame is suitable or not is discriminated, there is no fear to sew embroidery in a condition an unsuitable embroidery frame is set. Thus there is no need to display both a standard set embroidery frame and a non-standard set embroidery frame and only displaying a standard set embroidery frame is enough causing to enable the display area of an embroidery frame to be made smaller.
