Triggering device for small-size printer
专利汇可以提供Triggering device for small-size printer专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a small-size and highly durable printer consuming lesser amounts of electric power by using a system in which the coupling of a type ring shaft with grooves on its periphery and a type ring spring is released by operating an electromagnetic brake and the type ring is stopped.
CONSTITUTION: When coupling with the grooves 2 of a type ring shaft 1, a type ring spring 5 turning a type ring 4 is released from coupling with the grooves 2 by contacting of its head 501 with the slope of the head 701 of a selection claw 7 during the period when type is not selected, and the type ring shaft 1 runs idle. When selecting type, a coil 14 is electrically energized when the grooves 2 corresponding to a letter 3 to be typed come to the corresponding position of the type spring 5, a brake disk 12 is sucked and stopped, and a brake gear 11 is stopped. Whereupon, an epicyclic gear 10 driven by a selection claw shaft 8 is moved, the selection claw 7 is turned in the direction of anti-arrow d, and the type ring spring 5 is coupled with the grooves 2 and turned. Afterwards, when disconnecting the supply of power, the selection claw 7 is restored by the spring 19 and their coupling is again released.
