Abstract
PURPOSE: To compact and simplize the apparatus and secure operating connection by mounting gear and cam for controlling operation of each parts of the apparatus to a single drive shaft intensively and transmitting power to each parts.
CONSTITUTION: Rotation of a motor 101 is transmitted to a cam shaft 103 and all kinds of gear and cam 108W117 for controlling each parts of the apparatus are mounted intensively about the cam shaft 103 as common driving shaft. A gear 108 just turns a printing shaft 201. A cam 109 stops a printing wheel 201 by engaging with a positioning cam 204. A gear 110 turns reversely the printing wheel 201 and a cam 111 stops the printing whel 201. A pair of cam 112, 112 symmetrically positioned detaches a ink roller 501 from each cross printing wheels 202. A pair of cam 113, 113 symmetrically positioned press fits a platen 401 to printing wheels 202. A pair of cam 114, 114 symmetcially positioned deteches the platen 401 from the printing wheels 202. A gear 115 and a cam 116 operates signal generation mechanism 300 and cams 117, 117 vary the pressure of a spring plate 217 engaged with a printing wheel selection lever 208.
