PURPOSE:To enable printing wires to be easily guided skewly, by composing a tip guide of an outer guide plate and an inner guide plate provided respectively with a tapered hole and a tapered projection. CONSTITUTION:A tip guide 7 comprises an outer guide plate 7y, which has a tapered elliptic hole reduced in cross section toward a front end, and a plurality of semicircular groove 7d corresponding to the number of printing wires are provided on the inside of the hole. An inner guide plate 7x of the guide 7 has a tapered projection reduced in cross section toward the tip and provided with semicircular grooves 7c corresponding to the grooves 7d of the outer guide plate 7y. The inner guide plate 7x is inserted into the outer guide plate 7y in the direction of an arrow A, whereby the tip guide 7 for skewly guiding the printing wires 4 is formed. |
