Abstract

PURPOSE:To assemble a pinion easily, by providing an axial direction groove on the base part of a synthetic resin pinion, expanding the groove by utilizig elasticity, and fitting the base part into the supporting shaft. CONSTITUTION:Prior to assemble of a pinion 7, a number wheel 6 is assembled. subsequently, a pinion supporting shaft 5 is installed between frame side plates 2, 3 so as to be supported by them. On the pinion supporting shaft 5 which has been installed so as to be supported, a pinion is mounted so that one piece each is placed between each number wheel. In this case, since the pinion is formed by synthetic resin, a notch groove 75 of its cylindrical base part 71 can be expanded against its elasticity owing to a characteristic of its material. The pinion 7 is mounted onto the supporting shaft 5 through this expanded notch groove 75.
