To conduct sheet cutting with high efficiency and completely even for the corners of small articles to be disposed, such as post cards, various tickets, various type of cards, in such a condition that tens or hundreds of small articles are bound stacked, by remarkably-increasing sheet cutting force at the time of cutting the small articles to be disposed so as not to be made wrong use of, and attain reduction in its size and cost by eliminating use of a pressing mechanism for paper and documents to be cut, a link mechanism, a brake, a reduction mechanism and the like which were needed in the past.

A pair of positioning plates 2 of the right and left and positioning with adjacent two arms brought into contact with the sheet-cutting corner part of the small articles A to be disposed are formed at the upper surface front part of a cutting table 1 for placing and cutting the small articles A to be disposed, such as post cards, various tickets, various type of cards, a ram 3 is supported on the top surface rear part of the cutting table 1 through a pair of right and left guide shafts 4 so as to elevate freely by a required stroke, and a cutting blade 5 for cutting the corner parts of the small articles A to be disposed is fitted under the ram 3 so as to elevate freely in a drilling condition with a screw rod 6 screwed in the ram 3.
