PURPOSE:To prevent a type drum from pulsating, by a construction wherein an intermediate gear is provided so that it can be revolved around a shaft of a driving gear on the nipping side of a type drum gear, and is energized by a spring so as to mesh with the type drum gear and the driving gear. CONSTITUTION:A shaft 34 for the intermediate gear 31 is fixed to an oscillatable lever 33, and the spring 36 is fitted between the lever 33 and a spring holder 35 to energize the intermediate gear 31 so that the gear 31 is constantly meshed with the type drum gear 14 and the driving gear 30. Accordingly, no backlash is present between the intermediate gear 31 and the type drum gear 14, pulsation of the type drum is suppressed, and alignment of characters is enhanced. |
