Print hammer control means for pivotally mounted-type members
Abstract:
A printer has a plurality of print hammers which impact pivotaltype levers carried by type carriers moving along a track adjacent the print line. Cam surfaces on the body of the carrier cooperate with portions of the print hammer to prevent interference between the print hammer and an adjacent type lever when printing.
Abstract(Chinese):

打印机具有多个打印锤，该冲击锤撞击由沿着与打印线相邻的轨道运动的类型托架承载的枢轴式杠杆。 载体主体上的凸轮表面与打印锤的部分配合，以防止在打印时打印锤和相邻型杆之间的干扰。
