Abstract
An intermittent paper feed mechanism comprises a driving wheel rotationally driven in an intermittent manner, a driven wheel disposed opposite to and rotated by the driving wheel, a stopper means for restricting the angle of rotation of the driving wheel and a coiled return spring for biasing the driving wheel in a direction opposite to its rotational driven direction. The driving and driven wheels, the stopper means and the return spring are coaxially mounted on a common shaft. The device of the invention enables a paper on which characters are printed by a printing head to be advanced at a high accuracy in an intermittent manner without using a stepping pulse motor.
