Abstract
PURPOSE: To provide a typewriter which prevents the vibration of a carriage during its operation by composing the carriage for carrying typing head of special resin.
CONSTITUTION: In a typewriter such as a wire dot matrix type serial printer or the like, a type head 2 is moved in a direction perpendicular to the feeding direction of a sheet P to type serially. In this case, a carriage 1 for carrying the head 2 is formed of polyamide resin containing 8W19vol.% of lead [such as, for example, "DANPI" (trade name) made by Sogo Kaihatsu Co. and sold by Sumikin Shoji Co. model DP-1, DP-2]. Since the characters are indicated in matrix in the wire drive part of the head 2, the head can print at a speed being several times to several tens times of the actual typing speed upon typing, and accordingly vibration corresponding to the frequency will result. However, no resonance occurs by using the material, thereby reducing the noise.
