发明名称 Stylus for tabulating device
摘要 A punching stylus for tabulating devices wherein the stylus is inserted through a selected hole in a rigid top plate of the device and through an aligned tabulating card. The stylus comprises a slender, rigid rod having a hardened tip and mounted within a non-rigid handle member in such a way that the handle is flexible relative to the rod. Thus, in use, the rod of the stylus will not break if the stylus is moved laterally or bent over when inserted in the plate hole of a tabulating device.
