ABSTRACT:
An electronically controlled sewing machine indicates which of the basic operations for the machine is possible or impossible in a readily identifiable manner to a user, thereby improving the ease of operation of the machine. A start/stop button is illuminated with steady green light, that is, a first illuminated state, when a presser foot is at a pressing position and a needle bar is within a threading possible range. When the presser foot is at a withdrawn position and the needle bar is within the threading possible range, the start/stop button is illuminated with red flicker, that is, a second illuminated state. When the presser foot is at the pressing position and the needle bar is out of the threading possible range, the start/stop button is illuminated with green flicker, that is, a third illuminated state. When the presser foot is at the withdrawn position and the needle bar is out of the threading possible range, the start/stop button is illuminated with steady red light, that is, a fourth illuminated state. The indications by the different illuminated states make it easy for the operator to recognize which of the basic operations, including needle thread placement, needle threading, and so on, is possible or impossible. Alternatively, the indications can be provided by sound signals or messages presented on a display.
