Abstract

PURPOSE: To provide a typewriter, light and easy to operate, which is designed to print by use of a light type drum without using pushing or typing bar.
CONSTITUTION: A type drum 4 is constituted by fixing a belt 1 on which types 2 are arranged, and the type drum 4 is mounted on bed 16 in side-by-side relationship with platen 5. A carbon tape 6 is disposed between platen 5 and drum 4 perpendicularly to drum 4, and a printing hammer 7 is placed inside the type drum 4 in the manner spaced from the inner wall surface of drum 4. In case of selecting character A and then B in the typewriter arranged as above, key (10) of printing keys 17 is at first pushed, whereby a signal from input means 18 is afforded to memory 20 and control means 21 via relay 19. Here, since A is (21, 17) and B is (10, 20), a pulse signal for advancing 11 steps in minus direction along X-axis (10-21=-11) is given to X-axis pulse motor 14. Subsequently, when key (20) of printing keys 17 is pushed, a pulse signal for advancing 3 steps in plus direction along X-axis (20-17=3) is given to Y-axis pulse motor 8. Then, "positioning completed" signal is given to motor 15 and hammer 7 is driven for printing.
