Abstract
Predetermined pattern selecting and function selecting keys of an electronic sewing machine are employed for controlling the selection between normal operation of a stitch forming device and a built-in diagnosing device. The diagnosing device is enabled only when the power switch of the machine is on while the predetermined function selecting key is kept depressed, and the predetermined pattern selecting key is kept depressed for a predetermined time interval. The stitch forming device is enabled when the two predetermined keys are not depressed for the predetermined time interval.
