Abstract
A foot controller includes: a pedal portion that is to be depressed by a foot thereon; a pedal stand on which one end of the pedal portion is supported so that the pedal portion freely pivots about a pivot portion; a speed control member that controls an operation speed of a sewing machine; and a depression suppression member that regulates and controls a depressing operation of the pedal portion in accordance with the depression speed of the pedal portion. In response to a depressing operation which does not involve an abrupt speed change of the pedal portion, the depression suppression member is not operated and the operation speed of the sewing machine is controlled according to an amount of depression of the pedal portion. In response to a depressing operation which involves an abrupt speed change of the pedal portion, the depression suppression member is operated.
