are removably fitted.

Next, the supporting structure of the punch 7 and the punch actuating device will be described in detail. A support cylinder 27 is disposed inside the left side of the upper case 13 of the head 6 so as to extend in the vertical direction via a mounting plate 28. The punch 7 is fitted and supported in this support cylinder 27 so as to be movable up and down. Also, the lower end of the punch 7 has a cutting blade 7.
a is formed, and a large diameter head 7b is provided at the upper end. Below the punch 7, the lower case 14
A punching die 29 is fixed to the upper left side of the card C by a plurality of screws 30, and when the card C is punched in cooperation with the punching die 29 as the punch 7 moves up and down, the hole 29a of the punching die 29 is fixed. Through this, the drilling debris falls and is stored in the debris storage chamber 24 of the lower case 14.

Further, in this embodiment, all punch actuating devices for vertically moving the punch 7 are housed in the upper case 13 of the head 6. That is, the eccentric cam 3 is located approximately in the center of the upper case 13.
1 is rotatably supported by a substantially horizontal support shaft 32 extending in the front-back direction substantially parallel to the card C surface, and a motor 33 for punch operation as a drive source is supported on the right side inside the upper case 13. It is arranged via a plate 34. Motor 33 and eccentric cam 31
There are many gears 3 in the upper case 13 between the
A reduction gear mechanism 41 consisting of 5 to 40 is provided,
As the motor shaft 33a of the motor 33 rotates, the eccentric cam 31 is rotated once via the reduction gear mechanism 41.

In the upper case 13 between the punch 7 and the eccentric cam 31, a rotating member 42 having a substantially inverted U-shape on the side is provided with a support extending parallel to the support shaft 32 of the eccentric cam 31 at an approximately intermediate portion thereof. It is rotatably supported by a shaft 43. A pair of upper and lower cam contact pieces 44 are integrally bent at the right end of the rotating member 42, and sandwich the outer peripheral surface of the cam 31 from above and below with the support shaft 32 of the eccentric cam 31 in between. As the rotation member 31 rotates, the rotation member 42 is rotated back and forth within a predetermined range.

An operating piece 45 is fixed to the upper surface of the rotating member 42 at its right base end with a screw 46, and an abutting portion 45a that abuts the head 7b of the punch 7 from above is provided on the lower surface of the left free end. is installed protrudingly. or,
This actuating piece 45 is constituted by a bullet plate having elasticity that can withstand the drilling load caused by the punch 7.
When an overload exceeding the drilling load is applied to the actuating member 45, the free end of the actuating piece 45 bends upward as shown by the chain line in FIG. A pair of front and rear release pieces 4 are provided at the lower left end of the rotating member 42.
7 is integrally bent and engaged with the head 7b of the punch 7 from below while sandwiching the outer periphery of the upper end of the punch 7 from the front and back.

When the rotating member 42 is rotated counterclockwise in FIG. 1 with the rotation of the eccentric cam 31, the punch 7 is pressed downward via the operating piece 45, and the punch 7 The card C is perforated by cooperation with the die 29, and the rotating member 4
2 is rotated clockwise in FIG. 1, the punch 7 is moved upwardly away from the card C via the release piece 47.

Now, in the drilling machine configured as described above, each time the threaded rod 17 is rotated with the rotation of the motor 20 for moving the head, the head 6 is moved to the right or left by a predetermined amount via the female threaded body 19. It will be moved one by one. Further, each time the head 6 moves, the punch actuating motor 33 is selectively rotated based on a predetermined actuation signal, and the rotating member 42 is rotated back and forth by the rotation of the eccentric cam 31 accompanying the rotation of the motor 33. ,
The punch 7 is reciprocated with respect to the card C via the actuating piece 45 and the releasing piece 47 to punch a hole in a predetermined position of the card C.

Further, the punching slag generated as a result of this punching passes through the hole 29a of the punching die 29 and falls into the scum storage chamber 24 of the lower case 14 and is accommodated therein. Therefore, during drilling, drilling debris will not be scattered around, and the work can be carried out with peace of mind. Furthermore, when removing the drilling dregs accumulated in the dregs storage chamber 24,
By removing the cap 26 from the right end of the lower case 14 and opening the scum discharge port 25, drilling scum can be easily discharged and removed through the scum discharge port 25.

It should be noted that this invention is not limited to the configuration of the above-mentioned embodiments, and it is also possible to embody the invention by changing the configuration of each part arbitrarily within a range that does not depart from the spirit of this invention.

Effects of the invention As detailed above, this invention is effective in the upper case 1.
3, the punch 7, the rotating member 42, the eccentric cam 31, the motor 33, etc. are installed all at once, and the lower case 14 is provided with the punching die 29 and the waste storage chamber 24.
The upper case 13 and the lower case 13 including the punch actuating device etc. can be compactly assembled within a limited space and the appearance can be improved. Also, a discharge port 25 is provided in the waste storage chamber 24,
Since the discharge port 25 is covered by a removable cap 26, no matter where the head 6 is moved, the drilling debris can be collected in the debris storage chamber without being scattered around, and the upper case 13 and the lower case 14 are formed into a box shape of approximately equal length within the range of the horizontal length of the machine frame 1, and the upper case 13 and the lower case 14 are substantially aligned in the left and right direction and integrally fixedly connected. Therefore, when the drilling machine is not in use, by placing the head 6 in the original position of movement, both cases can be compactly housed within the range of the horizontal length of the machine frame 1 without protruding in the left-right direction of the machine frame. This also has the effect of having great practical value, such as preventing any of the cases from protruding separately in the lateral direction of the machine frame.
