摘要： Rotatably driven type wheels carrying type characters on the periphery thereof are supported resiliently about a normal operating axis for movement to a printing position to impact a selected type character against a recording medium. The movement of the type wheel to the printing position is accomplished by engaging a relatively stationary stop member with an abutment on the type wheel to stop the normal rotational movement of the type wheel and enable the associated rotational kinetic energy to pivot the type wheel about the stop member to impact the selected type character against the recording medium at the printing position. To ensure full engagement of the stop member with the abutment on the type wheel and reduce the accompanying stresses, the stop member yieldably engages the abutment prior to stopping the normal rotational movement of the type wheel.
