Abstract
The system responds to signals from a weight computer to depress selected keys on the postage metering machine keyboard. A solenoid is associated with each key. The solenoids are mounted on a carriage for movement toward and away from the keyboard. Spring bias and weight forces the carriage toward the keyboard. Energized solenoids hold an engagement tip extended so that when the carriage is released toward the keyboard, the carriage force will depress the selected key. The engagement tip on unenergized solenoids contact the key but the solenoid shaft moves upward into the solenoid without depressing the key.
