Abstract
PURPOSE: To enable an ink ribbon to be used effectively and for a longer time by a method wherein a cam for oscillating the ink ribbon in the widthwise direction simultaneously when conveying the ink ribbon, in the ink ribbon conveying mechanism of a small-sized printer.
CONSTITUTION: The ink ribbon 9 in a cassette 8 is conveyed by the rotation of gears 13, 14 which are driven by a motor 12. In this case, a ring-shaped cam 14a having periodically recessed and projected profile is formed on the lower surface of the gear 14, the cam 14a is in contact with a pin 16 fixed to a carriage 2 and oscillates the cassette 8 on a seat plate 11 in the direction of the arrow B as the gear 14 rotates. Accordingly, a hammer 3 faces alternately to the upper printing position 17 and the lower printing position 18 of the ink ribbon 9, enabling the ink ribbon 9 to be used effectively and for a prolonged time period.
