Keyboard recocking mechanism

摘要

A keyboard of a typewriter comprises a common actuator biased by a spring. The depression of a key causes a corresponding intermediate member to engage with the actuator to initiate an operating cycle and to move the intermediate member to a position which causes selection of an operation corresponding to the key which has been depressed. The engagement of the common actuator with more than one intermediate member consequent upon depression of more than one key causes the common actuator to move under the spring bias at a substantially reduced speed and a locking mechanism to lock selected operations. A reloading mechanism is responsive to the speed of the actuator for unlocking the locking mechanism and restoring the actuator and the intermediate member when the reduced speed is sensed.
