Abstract
A paper punch for use in combination with either a notebook having a pair of covers and a spine therebetween or with a ruler. The paper punch essentially comprises a punching element of unitary construction and formed of a hard yet resilient plastic material, preferably by injection in a mold. The punching element is formed with a pair of parallel spaced arms resiliently connected to one another at one end and featuring male and female punching members respectively disposed on the arms in operative association with each other. A slit is formed in one of the arms in a plane normal to the punching members and bisecting the female punching member. In a normally inoperative position, the male punching member is partially disposed within its cooperative female member in close proximity to the slit, and in an operative position, the male punching member is fully disposed within its cooperative female member, traversing the slit. Preferably, cooperating alignment members also are formed on the arms to secure the alignment of the punching members.
