RELEASE AND BLOCKING MECHANISM FOR POWER OPERATED TYPEWRITERS |
摘要 |
<p>A shift release mechanism is connected to an electrical switch and to a control knob on a power operated typewriter. Operating the control knob actuates the electrical switch from a closed state to an open state and actuates the shift release mechanism for releasing a shift keylever to cause a platen supporting carriage to move from an upper position to a lower position. The shift release mechanism further includes a finger positioned to block the depression of the shift keylever when the electrical switch is in the open state.</p> |
