    摘要： The mechanism has a drive roller which engages the cord that opens and closes a closure member such as a drapery. An electric motor that rotates the driver roller is supplied with power through first and second timed switches. An adjustment associated with the first timed switch may be set to control the times at which power to the electric motor is initiated, while an adjustment associated with the second timed switch may be set to determine the interval after which power to the electric motor is terminated.
