PURPOSE:To relieve a typist of wear, by a method wherein an action-expanding mechanism is provided, a type pushing-up rod is operated by a rotary solenoid, and a type bar is started moving for automatically typing. CONSTITUTION:An opening and closing plate 10 is moved through a key lever 1 by slightly depressing the action-expanding mechanism, and is made to pass by a sensor 11 to drive the first rotary solenoid 6. Then, the plate 10 is turned to pass by a sensor 11', and the second rotary solenoid 12 is driven to move a type bar 17, thereby typing. Accordingly, the first and second rotary solenoids are driven for typing while electrically staggering the timings by a small movement of the action-expanding mechanism, so that the typist can be relieved of wear. Further, since actions are effected sequentially and the construction is simplified, thereby the device is made free of troubles. |
