Further, a vertical hole 10 is formed in the slider 8 in the vertical direction, and a punching rod 11 is fixed to the vertical hole 10 by a screw 12. A discharge groove 13 for discharging the chips cut by the punch rod 11 and a locking groove 14 for restricting the upper limit position of the slider 8 are formed above the middle portion of the slider-8.

A sliding shaft guide member 15 is fixed to the front surface of the slider 8 by a screw 16 or the like, and a sliding shaft 17 is slidably inserted into the guide member 15. There is. A paper pressing plate 18 is fixed to the lower end of the sliding shaft 17, and the paper pressing plate 18 is urged downward by an elastic member 20, and a stop ring (E ring) 21 is provided on the upper end of the sliding shaft 17. Is fixed to prevent the guide member 15 from falling out. Further, the paper pressing board 18 is provided with a pressing board 22 as shown in FIG.

A bracket 23 is fixed to the front surface of the guide member 15, and a weight body 24 is pivotally attached to the bracket 23 by a pin 25 so that the weight body 24 can swing freely below the weight body 24. It is adapted to be engaged with the upper end of the engaging member 26 fixed inside the support body 2. In front of the weight body 24, a lock release member 27 for pressing the weight body 24 to release the engagement with the lock member 26 is attached so as to be able to move forward and backward. The unlocking member 27 is fitted to the resinous bush 28 with a certain fitting force.

Further, a positioning member 29 for positioning a hole to be drilled is arranged on the rear of the upper surface of the base 1 so as to be movable forward and backward and to be fixed by a screw 30. A sliding groove 32 is formed in the lower plate portion 31 of the positioning member 29.

Further, on the upper surface of the base 1, a slide base 33 on which a sheet bundle W is placed is arranged in forward and backward movement, and at the rear end of the slide base 33, the rear end of the sheet bundle is provided. A positioning piece 33a for aligning the positions is formed. A step portion 34 is provided on the lower surface of the slide base 33, and the step portion 34 engages with the slide groove 32 of the positioning member 29, so that the slide base 33 is moved to the most forward position, the last position. The retreat position is regulated.

When the length of the sliding groove 32 in the vertical direction is the moving amount Y of the slide base 33, the moving amount Y of the slide base 33 is from the center of the recess 1a to the center of the drilling rod. Is set to be the same as the distance X (see FIG. 9).

On the side surface of the slide base 33, a movable width adjusting member 35 is arranged so as to match the lateral width of the sheet bundle to be punched. A paper retainer 36, which prevents the bundle of sheets from coming apart, is fixed to the end of the width adjusting member 35 so as to be vertically movable.

Next, the operation will be described. When the locking release member 27 is pressed from the state shown in FIG. 2, the weight 24 is pressed in the direction of the sliding shaft 17 and is displaced to a position displaced from the upper end of the locking member 26. When the pressing lever-3 is rotated in this state, the rotating action is converted into a linear action by the link mechanism of the cam disk 5, the pressing body 6 and the slider 8, and the punching rod 11 is lowered. Further, when the pressing lever-3 is rotated, a hole is made in the sheet bundle W. The paper pressing platen 18 is stopped at a position where it is lowered to some extent according to the thickness of the sheet bundle W, and only the punching rod 11 is lowered. After finishing punching, the pressing lever-3 is rotated in the reverse direction to pull out the punch rod from the sheet bundle W. However, the sheet holding plate 18 (and the action of the elastic member 20) presses the sheet bundle W downward. Therefore, the sheet bundle does not rise together with the punching rod 11.

Further, when the pressing lever 3 is rotated in the reverse direction and the slider 8 rises, the weight body 24 also rises, and in the process of raising the weight body 24, the locking release member 27 is pressed and returned to the original state. Due to this returning operation of the lock release member 27, the perforating rod 11 does not descend unless the lock release member 27 is pressed.

Next, a description will be given of the case where the boring position is changed and the stopper 38 is used. When it is desired to make the hole to be punched deeper than the end of the sheet bundle, first, the stop ring 39 is placed in the recess 1a, the positioning member 29 is retracted, and the positioning member 29 is fixed by the screw 30. Then, the bundle of paper is placed on the upper surface of the slide base 33, and the rear end of the bundle of paper is brought into contact with the positioning piece 33a and arranged. Then, the rear end 34a of the step portion 34 of the slide base 33 is retracted until it comes into contact with the front end portion 32a of the sliding groove 32. After the perforation is completed in this state, the slide base 33 is pulled out until the front end surface 34b of the step portion 34 comes into contact with the rear end portion 32b of the sliding groove 32.

As described above, since the movement amount Y of the slide base 33 and the distance X from the center of the recess 1a to the center of the cutting blade are set (formed) to be the same, The drilled hole is always located above the stop ring 39. Next, the main body of the stopper 38 is inserted into the perforated hole, and the support ring 40 (locking protrusion 40a) is fitted to the stopper ring 39.

If the fitting to the retaining ring 39 is hard, the pressing plate 22 is pulled out forward, the pressing lever 3 is rotated, and the paper pressing plate 18 is lowered. By the lowering operation of the paper pressing board 18, the pressing board 22 presses the flange portion 40b of the stopper 38 via the elastic member 20, and the support pillar portion 40 (locking protrusion 40a) is fitted to the stop ring 39.
