ABSTRACT:
A paper cutter comprising: a bed for placing paper to be cut thereon; a rail mounted on the bed; a slider made slidable along the rail; and a rotary blade carried by the slider for cutting the paper as the slider is moved. Further comprised are springs for supporting the two ends of the rail therethrough on the bed so that the rail may move up and down. The rail has its lower face formed on its end edge with a cutting position determining face such that the slider is fitted on the rail in a position where the rotary blade runs along the positioning face. With this construction, the rail itself is supported in a floating state on the bed. As a result, the paper is cut with the rotary blade by lowering the floating rail with the depression of the slider and by clamping the paper under pressure only at the portion to be cut between the rail and the bed as the slider is moved. Thus, the construction is simplified with little cutting resistance, and the paper is not displaced even if clamped at the portion between the rail and the bed.
