Typing apparatus
专利汇可以提供Typing apparatus专利检索，专利查询，专利分析的服务。并且PURPOSE: To exactly return a carriage in a typing apparatus by retaining an engaging member of a takeup unit for engaging a type head against a spring to a released position by the drive force of a paper feeding shaft.
CONSTITUTION: When a rotary shaft 6 rotates to allow a desired function symbol to be located at a typing position, a drive shaft 13 rotates to permit a hammer cam 12 to urge a type hammer 11, and to accordingly cause the hammer 11 to urge a recording paper 14 onto a function symbol type wheel 14 to type the function symbol on the paper. When one figure is completed, a carry wire 8 is tensioned in a direction as designated by an arrow to shift the carriage 3 leftwardly for one figure, and to simultaneously shift the numerical type wheel 5 retained at a carriage arm 3a to the second figure. Thus, the type wheel 4 urges leftwardly by a spring 14 to shift it leftwardly to stop at the position confronting the cutout portion 11a of the hammer 11. On the other hand, the carriage 3 is shifted to the second figure, and when the desired numeral is moved to the position to be typed, it types the type in the second figure by similar operation to the above. When the typing operation is completed, the takeup member of the wire 8 becomes free to cause the carriage 3 to be returned to the initial position by the tension spring 7.
