る。However, in the above-mentioned first drilling machine, the vertical movement of the drilling blade is inefficient due to manual operation while using a motor, and the second drilling machine requires two motors. Since the motor is used, the weight becomes heavy and there is a problem that handling convenience such as movement is poor. Further, in the third punching machine in which the punching blade is not rotated, there is a problem that a predetermined punching cannot be performed depending on paper quality or the like. An object of the present invention is to provide an office drilling machine in which convenience is improved and punching efficiency is improved by driving the lifting and lowering of the punching blade and the paper press and the rotation of the punching blade with a single driving machine. That is.

幅に改善され、また、従来の穿孔刃の昇降を手動で行う
穿孔機及び穿孔刃が回転しない穿孔機と較べ、紙質等に
影響されることなく所定通り正確に穿孔できることから
穿孔効率に優れた事務用穿孔機である。The office drilling machine according to the present invention uses two conventional driving machines because the lifting and lowering of the punching blade and the paper holder and the rotation of the punching blade are driven by one driving machine. Compared to the case, the convenience in handling such as movement is greatly improved because it can be reduced in weight, and in comparison with the conventional drilling machine that manually moves the drilling blade up and down and the drilling machine where the drilling blade does not rotate, paper quality etc. This is an office drilling machine with excellent drilling efficiency because drilling can be performed accurately as specified without being affected.
