Description

[Detailed Description of the Invention] Purpose of the Invention The present invention provides a punch for punching a through hole with a diameter of about 61 mm on one side of a document in order to insert the document, and a reinforcing piece for reinforcing the periphery of the through hole. An improved document that is provided with a pasting mechanism and further provided with a type 41 pressing mechanism inserted into the punch that is activated immediately before the mechanism is activated so that the reinforcing piece can be beautifully and reliably pasted onto the document. It's about punches.

Industrial Application Fields and Prior Art In a document in which several through holes are made on one side of the document and the document is inserted into a loose-leaf notebook or the like through the holes,
There is a drawback that the area around the hole is easily torn, so in order to reinforce the area around the hole, a reinforcing piece such as a thin plastic piece is placed in advance on the part of the document where the hole is to be punched.
Punches are already known which are then used to punch holes in documents together with the reinforcing piece. (Mikoaki!
M-46718, Utility Model 56-58799, Utility Model 57
(Refer to -45999) Also, the reinforcing piece is attached to a release tape, the release tape is wound around a cassette container, the cassette container is assembled into a hole punch, and the release tape is fed out from the cassette each time a hole is punched in a document. A version with K that allows a reinforcing piece to be attached to the document has already been proposed. (Jitsukai 57-15
3500, No. 57-43998) Problems to be Solved by the Invention However, these conventional methods are designed to be possible if the quality of the document (paper) to which the reinforcing piece is to be pasted is thick. Therefore, there was a drawback that thin paper that required a reinforcing piece to be attached could not be used on the side sole.

Means for Solving the Problems In order to solve the drawbacks of the conventional hole punch equipped with the reinforcing piece attachment mechanism, the present invention provides a hole punch shaft that is constantly elevated above the base at a specific height. A device is provided on a support plate on a base to which a handle to which the handle is attached is pivoted, and is constantly biased by the support plate to press the base next to the punch shaft. The device is characterized by being equipped with a device that locks onto the handle and pulls it away from the base just before returning to the base, and the document to be punched in this way is sent out for pasting a reinforcing piece to it. It is possible to prevent the reinforcing piece from sticking to the adhesive and being pushed back from the correct position on the base, or from being wrinkled. Even though the paper was made of thin paper, it was possible to create an excellent document punch that could beautifully attach the reinforcing piece to the exact position of the document to be punched.

Embodiment Figure 1 shows a pair of through holes AI on one side of document A for inserting document A into a loose-leaf notebook.
, A2 is shown as an example, and those holes At, A21C,
This shows an example in which reinforcing pieces B, B for reinforcing the periphery of the hole are attached, and the reinforcing piece BK also has through holes Al, A2. However, the purpose of this invention, which will be explained below, is not limited to drilling such a pair of holes AI and A2.
Needless to say, even if a single hole is made, or if three or four holes are made, it is within the technical scope of the present invention.

Figure 2 shows a pair of six A1 and A2 on one side of document A in Figure 1.
This figure shows 10 examples of punches that can be opened at the same time with one handle operation, and the punch 1 includes a base 10, a handle 2, a support plate 3 that attaches the handle 2 to the base 1°,
It is made up of a cassette 4 containing a chive C (see Fig. 7) to which a reinforcing piece B- is attached.

As can be seen in Figure 3, the base 10 is formed so that the right half of the figure, that is, the front half 11, is about three times higher than the height of the rear half 12, and the front half 11 has document holes AK, AI, and A2. It is a part with a mechanism, and the rear part 12 is a part with a cassette 4.
It has a low platform shape to facilitate the operation of assembling it into or taking it out from the base 10.

A friction plate 9° such as a rubber plate is attached to the bottom of the base 10 to prevent the punch 1 placed on the desk from slipping on the desk.

The rear half part 110 (hereinafter referred to as the central part 110 of the base) of the front half part 11 of the base has a length approximately equal to the length of the base 10 in the front-rear direction, and the height of this part 110 is equal to the length of the base 10 in the front-rear direction. s11
It is several χ (approximately 5χ) higher than the first half 11, and this height difference is convenient for inserting the document A to be punched into the front half 11.

A seat plate 30 having the width of the base 10 is attached to the flat top surface of the central portion 110, and the seat plate 30 has sleeve portions 31.5 through which a pair of hole punch shafts 5.5 pass. 31
is long and protrudes above the front half 11.

The seat plate 30 has a support plate 3.3 whose left and right ends are long enough to reach the front end of the sleeve portion 31, and whose height is about the same as the height of the central portion 110. Support plate 3.3
The upper sides 52 are each bent horizontally inward of the base 10, and a guide hole 33 for raising and lowering the punch shaft 5 is provided in the front part thereof.

The punch IJ1115 has a pin 20 suspended horizontally on the handle 2 that penetrates through its midsection so that it can be moved up and down through the guide hole 33, through holes 34. In particular, the through hole 14 on the top surface of the front half of the base 11 is
In order to beautifully open I and A2, we made a metal plate 11m through hole 1.
4, and attach the metal plate 13 to the front half of the base 11.
There's an i on top. Note that the inside of the front half 11 of the base is hollow, and pieces of paper with punched holes A1 and A2 are collected in the hollow, and can be taken out as needed.

The handle 2 has the same width and somewhat shorter length as the base 1o, but the base 21 is largely hollowed out in the center, leaving the part necessary to support the punch shaft 5. This is to make it easier to confirm the position of the document A inserted on the front half 11 of the stand.

The handle base 21 has a shaded vertical cross section that is large enough to allow the upper side of the support plate 3 to be inserted loosely into it, and the handle base 21 has a shaded vertical section that allows the upper side of the support plate 3 to be inserted loosely therein.
At the point where it overlaps with the front end, the handle base 21 and the support plate 3
It is supported by a support shaft 22 that passes through the front end in the horizontal direction, and the handle free end 23 can be rotated up and down using the support shaft 22 as a fulcrum.

In order to constantly raise the free end 23 of the handle 2 to a certain height above the base 10, the spindle 22&c spring is wound six times, and the resilient ends 24, 24 of the spring are connected to the top of the seat plate 50 and the handle 2. It acts on the inner surface of the body. Note that the pin 20 for raising and lowering the punch shaft 5 is attached to the root portion 2 of the handle 2.
It is suspended horizontally on the handle 2 at a position further rearward than the handle 2 , and that position is also rearward of the support shaft 22 . and the pin 20 is connected to the handle free end 2 in the raised position.
When the support plate 5 is pushed down, it descends while drawing an arc-shaped trajectory with the support shaft 22 as the fulcrum, so a long vertical hole is drilled in the support plate 3 to prevent this movement from being hindered (
(not shown), the pin 20 crosses within the elongated hole. Therefore, the elasticity of the spring 24 causes the free end 23 of the handle to rise when the push-down blade on the handle 2 is released, but the rise is stopped when the pin 20 abuts against the upper end of the elongated hole.

The stopped state is shown in Fig. 2.3.

A document holding mechanism 6 is provided using the lifting and lowering of the pin 20. As can be seen in FIG. 4, the mechanism 6 is made of a rather wide holding plate 6, and the holding plate 6 has an elongated hole 60 in its center, and the elongated hole 60 is engaged with the pin 20. ing. Further, the presser plate 6 is provided so as to rise and fall over the outside of the support plate 3, and the upper end of the presser plate 6 is bent onto the upper side 32 of the support plate so that the bent portion 61 does not get in the way of the punch shaft 5. It has two prongs or a through hole, through which the punch shaft 5 can move up and down as shown in FIG. A leaf spring 65 having a hairpin-like elasticity that constantly presses the bent portion 61 against the upper side 32 of the support plate is incorporated so as to press the bent portion 61 and the upper side 52 of the support plate. Therefore, the elasticity of the leaf spring 650 constantly presses the lower end of the holding plate 6 onto the front half 11 of the base as shown in FIG.

Note that the hairpin-shaped leaf spring 65 has a through hole through which the punch shaft 5 passes.

The vertical hole 60 of the holding plate 6 is long enough to allow the pin 20 to descend when pressing down on the handle 2 to make a hole in the document AtC.
When the push-down blade is released, the handle 2 automatically rises by the spring force 24, and just before returning to its uppermost position, the handle 2 is brought into contact with the upper end of the vertically elongated hole 60 by 5 kt. When returns to the top position, pin 20
Then, the holding plate 6 is also slightly raised against the elasticity of the leaf spring 65, and as shown in FIG.
The length is set so that it rises by a few percent from the top.

As mentioned above, when the document punch 1 is not in use, the document holding mechanism 6 has the handle 2 raised to the above position, and at the same time the holding plate 6 is also in the raised position R. There is no problem in inserting document A onto the front half 11. To make holes AI and A2 in the inserted document A, K
``When the handle 2 is pushed down, the pin 20 drops from the lower end of the vertical hole 60 at that moment, so the holding plate 6 is pressed against the leaf spring 65.
As soon as it comes out, it descends and presses document A onto the front half 11 of the base. This prevents the reinforcing piece B from moving to the document or causing wrinkles on the document A, which tends to occur when pasting the reinforcing piece B, and ensures that the reinforcing piece B is stuck to the document A in its designated position. And it has certain characteristics that make it beautiful.

That is, the reinforcing piece B is pasted at specific intervals with release tape K and CVc as shown in Figure 6.7, and the tape C is attached to the cassette 4.
When tape C is fed out from cassette 4 as shown by the arrow in FIG.
The reinforcing piece B is sent out onto the front half of the base 11 while slipping off naturally.The reinforcing piece B that is sent out in this way has a long extension from the cassette 40 opening onto the document A. The peeled edge is bent over onto the document A, and is sent out in the direction of the arrow until it is completely peeled off from the release tape C. Due to this tendency of the reinforcing piece B to fall down and become stiff, the adhesive surface B1 of the reinforcing piece B will continue to move on the document A as shown by the arrow, with the fallen part of it touching the document A. At this time, document A is also pushed back in the direction of the arrow. If document A is made of thick or hard paper, simply holding document A in your hand will cause reinforcing piece B to slide over the document and stick to the designated position on document A; If the reinforcing piece B is weak, even if the document is held in place by hand, there is a risk that the feeding of the reinforcing piece B may wrinkle the document A below it, and in that case, the reinforcing piece B may wrinkle the document A to which it is attached. While the paper is wrinkled, the next stage of drilling is performed, which not only makes the reinforcing piece affixed look bad, but also prevents the reinforcing piece B from providing sufficient reinforcement to the document A.

The above-mentioned document holding mechanism 6 solves this drawback of attaching the reinforcing piece B. Namely, as mentioned above, as soon as the handle 2 is started to be pushed down, the document A is held at a position close to the hole punching position. Since it is pressed onto the front half 11 of the stand, the reinforcing piece B, which is sent at an angle, can slide on the top surface of the MA, and the reinforcing piece B can be accurately attached to the predetermined position of W type A. . In order to prevent the holding plate 6 from rising unnecessarily, a small protrusion 67 is provided on the side of the supporting plate 3.
is provided so that the step of the presser plate 6 abuts against it.

Even if the reinforcing piece B is only stuck to a predetermined position on the document A, and the punch axis 5 punches a hole in the document person along with the reinforcing piece B, the reinforcing piece B is not necessarily firmly stuck to the document A. . Therefore, after the reinforcing piece B is stuck to a predetermined position of the document A, a mechanism 7 is provided which makes a hole while pressing the reinforcing piece B and the document A onto the front half 11 of the base.

(See Fig. 3) The mechanism 7 is configured so that a pressing plate 70 having just the right width to press down the reinforcing piece B faces the lower side of the sleeve portion 31 of the seat plate 30, and is pushed forward from the pressing plate 70. The protruding part is bent upward at the front end of the sleeve part 51, and furthermore, the upper surface of the sleeve part 31 has a considerable distance therebetween, and the part is folded upward to form a pressing actuating plate 71. The rear end of the actuating plate 71 extends above the seat plate 30. The pressing plate 70 and the pressing operation plate 71 have holes 72 through which the co-busy bunch shafts 5 pass.
．． 73, therefore, the pressing plate 70 can press the document A onto the front half 11 of the base from above the document A to which the reinforcing piece B is attached.

In order to keep the suppression plate 70 constantly raised and pressed against the back side of the sleeve portion 31, a leaf spring 74 is installed in the rear half of the pressing operation plate 71.
is attached, and the tip of the leaf spring 74 elastically extends in the direction of the punch shaft 5 and engages on the pin 2°. mosquito(
The pressing plate 71, and therefore the suppressing plate 70, are constantly raised by the leaf spring 74 when the handle 2 is in the raised position, and at this time, the document A moves it on the front half 11 of the base to a predetermined drilling position. can be inserted.

Note that a long winding spring 75 is wound around the punch shaft 5' above the pressing operation plate 71, and the upper end of the spring 75 is
Normally, that is, when the handle 2 is raised, no action is applied to the pin 20.

In the mechanism 7 described above, when the handle 2 is pushed down to make a hole in the document AIC, the document holding mechanism 6 first descends and presses the document A onto the front half 11 of the base, as described above. At this time, although the bottle 20 descends somewhat, the leaf spring 74 engaged with the core pin 20Vc only slightly weakens its elastic force and still presses the suppressing plate 70 against the back side of the sleeve portion 31.

In this way, when the handle 2 is pressed down, one sheet of the reinforcing piece B is removed from the cassette 4 incorporated in the base IQK while the suppressing plate 70 is not yet lowered.
The upward sending action is the ratchet lever 8 shown in the chain diagram in Figure 4.
The ratchet lever 8 is moved from the position indicated by the solid line in the figure, and the handle 2 is subsequently pushed down.

Then, the leaf spring 74 that is engaged with the pin 20 will be lowered as the pin 20 is lowered, so the suppression operation plate 71 will be lowered for the first time in this operation. Place it on half 11. In this way, the pressing plate 70 can hold the document Ak.
Press down the stuck reinforcing piece B from above.

The subsequent depression of the handle 2 further lowers the pin 20, so that the bottle 20 now compresses the helical spring 75 on the pressure actuating plate 71, and thus the spring force 75 causes the pressure plate 70 to force the front half 11 Press the reinforcing piece B onto the document AK firmly.

Also, when the punch shaft 5 is in a state of being crimped to the side 5,
descends and drills the document AIC holes A1 and A2 together with the reinforcement KB. (See Figure 5) The cassette 4, which feeds out one reinforcing piece B with one push-down operation of the handle 2, is made of plastic whose side surface is snail-shaped, as shown in Figure 6.7.8. It has a container 40, the width of which is somewhat wider than the diameter of the reinforcing piece B, and is large enough that the release tape C to which the reinforcing piece B is attached can be fed out without shaking much inside.

Since the release tape C and the reinforcing piece B are already known, a detailed explanation of their materials etc. will be omitted, but in the example shown in and -, the reinforcing piece B is circular and one side is The adhesive surface B1 is used to adhere to the release tape C at specific intervals.

There is a small hole B2 in the center of the reinforcing piece B, and the small hole B2 is a hole through which the release tape C also passes.

A mechanism for feeding out the tape C from a cassette container 40 in which the release tape C is wound up and stored is provided in a tape delivery chamber 41 connected to the side surface of the container 40.

The tape C feeding mechanism is made up of a tape feeding roller 50 provided at the center of the feeding chamber 41, and the feeding roller 50 has the same width as the width of the feeding chamber 41.
Therefore, the tape C can be completely placed on that surface.There are ratchet wheels 51 and 51 on both left and right end surfaces of the roller 50 that protrude outward from the wall of the delivery chamber 41, and the end of the ratchet wheel 51 has a short length. The shaft 52 is engaged with a bearing plate 42 protruding from the tape delivery chamber 41, and the roller 50 is supported so as to be rotatable in the tape delivery chamber 41. For this reason, it goes without saying that holes 43 through which the ratchet wheel 51 can rotate are provided in both left and right walls of the tape delivery chamber 41. (See Figure 2.5) Small protrusions 53 are provided at specific intervals along the center line of the circumferential surface K of the tape feed roller 50.

The small protrusion 53 is attached to a release tape C placed on the circumferential surface of the roller 50.
When the roller 50 rotates, the tape C is wound onto the roller 50 and sent out. It is determined based on the relationship between the number and position of the claws of the wheel 51 and the spacing between the small holes B2 of the release tape C.

The small protrusion 551C of the roller 50 is placed close to the circumferential surface of the roller 50 in order to ensure that the small hole B2 of the tape C is engaged and the tape C is reliably fed when the roller 50 rotates. Tape guide plates 43 are protruded from the left and right side walls of the delivery chamber 41 so as not to obstruct the rotation of the small projections 53 of the rollers 5o. The guide plate 43 is K as seen in FIG.

In the upper part of the delivery chamber 41, a cover plate 47 provided on the upper side of the delivery chamber 41 has a tape folding plate 4 provided below the delivery port 44 at the front end.
5, but the lower part ends at just enough to surround the semi-circumference of the roller 50.

The reinforcing piece B is adhered to the release tape C at its adhesive surface B1, and the release tape C is wound up and housed in the container 40Vc with the attached reinforcing piece B facing upward. In order to automatically peel off the reinforcing piece B from the release tape C, it is necessary to fold the tape C sharply downward. Therefore, the upper part of the tape guide plate 43 is provided to protrude into the feeding chamber 41 so that the tape C can run along the upper side of the tape feeding chamber 41, and the tape folding plate 45 is connected to the tape guiding plate 43K.
M is provided above the delivery chamber 41, and protrudes from the delivery chamber 41 by several χ at its tip. Furthermore, this folding plate 45
As shown in the figure, the tape C is rapidly folded back and travels at the tip of the tape C, so a considerable repulsion force is required during the travel. Therefore, if one side wall of the tape delivery chamber 41 is designed to be removable, a holder 46 for the folding plate 45 is required on that side wall.

The upper surface of the tape delivery chamber 41 is provided with a cover plate 47 to prevent the peeling tape C from being touched by hands, and the tape delivery end of the cover plate 47 protrudes from the delivery chamber 41 by a number is formed.

On both left and right end surfaces of the tape feed roller 50, at a position close to the circumferential edge of the roller 50 and at the same spacing as the pawls of the ratchet wheel 51, there is a slight length of approximately 10°C.
A groove 54 is provided with a specific length.

This is shown in dotted lines in FIG. An outer plate 48 having protrusions 49 that protrude into the grooves 54' is provided by cutting and raising the left and right wall plates of the delivery chamber 41. The outer plate 48 normally protrudes to both left and right sides of the delivery chamber 41 as shown in the figure, and therefore the projections 49 protrude from the grooves 54. Therefore, the roller 50 can rotate freely, which allows the release tape C contained in the cassette 4 to be easily wound onto the feed row 50.

The same number of stopper grooves 55 as the small protrusions 53 are provided, and resilient claws 56 that fall into the wave grooves 55 are provided to protrude upward from the lower side wall of the delivery chamber 41.

A separating piece 57 for separating the tape C fed by the tape feeding roller 50 from the surface of the roller 50 is provided at the bottom of the feeding chamber 41, and the edge of the separating piece 57 protruding from the feeding chamber 41 is serrated. No. 58 is used for cutting the tape C, and one is for cutting the tape C.

As can be seen in FIG.
The tape is pulled out from the tape outlet 44, rapidly turned downward by a folding plate 45, passed between a guide plate 43 and a roller 50, and sent out to the front of the delivery chamber 41 at the lower side of the delivery chamber 41.

In order to assemble the cassette 4 into the punching bunch 1 as shown in FIG. 2, the rear half 12 of the bunch base is provided with a groove 15, 15 through which the width of the cassette 4 can pass. The center line of the groove 150 in the longitudinal direction coincides with the center line of the punch shaft 5, and thus the reinforcing piece B separated from the release tape C is affixed to a predetermined position of the document A inserted on the front half 11 of the base. can do.

In order to make it easier to insert or pull out the cassette 4 into the groove 15.15, the back half 12 of the base is so low that the ratchet wheel 51 of the cassette 4 does not touch it, and the cassette 4 is placed in a suitable position at the bottom of the groove 15. A recess 16 into which a protrusion 59 protruding from the bottom falls is provided to prevent the cassette 4 assembled into the groove 15 from sliding out of the groove 15 unnecessarily.

A ratchet wheel 51 and its bearing plate 42 protrude from both left and right sides of the cassette 4. Therefore, the central portion 110 of the punch 1 has a cavity wide enough to allow this bearing plate 42 to pass through, and the seat plate 30 mounted on the central portion 110 has a height that allows the tape delivery chamber 41 to fit between it and the bottom of the groove 15. It is installed with The front half 11 of the base has a vertical wall 17 at the rear of the punch shaft 5, and the # wall 17 is shaped so as to abut the front end of the cassette 4 inserted into the groove 15.

(See FIG. 5) A wart 18 is provided on the upper side of the vertical wall 17 and protrudes slightly above the surface of the metal plate 13. This is effective in preventing sagging at the bottom and allowing the reinforcing piece B to stick beautifully to the document A.

It is locked to the ratchet wheel 51 of the cassette 4 incorporated in the punch 1,
A ratchet lever 8 is attached to the handle 2, which causes the ratchet wheel 51 to rotate one pawl each time the handle 2 is pushed down. The lever 8 has a cut groove 3 formed on the rear edge of the seat plate 50.
A part of the lever 8 is inserted through the cut groove 35, and slides within the cut groove 35.
5, and can be freely rotated using the pivot stop 25 as a fulcrum. However, the lever 8 has a tension spring 81 tensioned between it and the handle shaft 22 at a position below the shaft stop 25, so that the lever 8 always keeps a part of it in the cut groove 35.
The body is urged to press into the deep part of the body.

The free end (tip) 82 of the ratchet lever 8 is connected to the windmill 51
When the handle 2 is in the raised position, the windmill 51 is bent into a hook shape so that it can be easily engaged with the claw of the
The tip B2 is always facing one of the claws. In addition, the sliding side that fits into the cut groove 35VC of the lever 8 has a specially shaped cam 8.
0, therefore, when the handle 2 is pushed down to the position shown in chain lines as shown in FIG. turned in the direction. However, windmill 51 is part 1.
When the claw is turned, the lever tip 82 immediately comes off the claw as shown in solid line in FIG. 4, thereby preventing the release tape C from being unnecessarily fed out from the cassette 4.

As mentioned above, the sliding direction of the ratchet lever 8 is controlled by the cut groove 35, and the side on which the ratchet lever tip 82 acts on the ratchet wheel 51Vc is the side of the cassette 4 incorporated in the base groove 15 in this example. This is the inner side of punch 1. However, the cassette 4 has windmills 51 protruding from both left and right sides. Therefore, punch 1 to cassette 4.
The ratchet lever 8 can send out the release tape C from the cassette 4 no matter which side of the base groove 15 it is installed in.

When the ratchet lever tip 82 engages the windmill 51,
The tip 82 is connected to the outer plate 48 protruding from the side of the cassette 4.
(See FIG. 7) so that it is flush with the side wall of the cassette 4 (See FIG. 4).

At this time, the protrusion 49 on the outer plate 48
50 enters the concave groove 54VC, and the handle 2 is pushed down forcefully.[However, the roller 50 only rotates within the range of the concave groove 54 into which the protrusion 49 has entered.

This prevents the reverse rotation of the roller 50 and prevents the tape C from being pulled back into the cassette 4.

The reverse prevention mechanisms 55 and 56 of this roller 50 are connected to the handle 2.
When the push-down operation is released and the handle 2 suddenly returns to the raised position by the spring 24, the ratchet lever tip 82
acts on the claw tree 51 and prevents the windmill 51 from being reversed.

After the reinforcing piece B is peeled off, only the release tape C is sent out from the punch 1 sequentially from the bottom of the cassette 4 through a passage 19 made on the bottom plate of the front half of the base 11. The outlet can be cut appropriately with a serrated cutting blade.

The reinforcing piece B may not necessarily need to be attached to the documents A&C. In that case, the cassette 4 can be removed from the punch 1;
A mechanism is provided to prevent the reinforcing piece B from coming out of the cassette 4 even when the reinforcing piece B is assembled.

As seen in FIG. 3, a shallow groove is provided on the top surface of the central portion 110 on the underside of the seat plate 30 mounted on the punch central portion 110, and an actuating plate 85 that slides in the corrugated groove is provided. A knob 87 is fitted into the actuating plate 85 and protrudes upward from a part of the actuating plate 85.
The knob 87 is made to protrude slightly above the seat plate 30 from the longitudinally long window hole 36 made in the seat plate 30. There is no conversion lever 88 that projects slightly into the cavity into which the cassette 4 is placed and abuts against the cam 80 of the ratchet lever 8.

In this configuration, when the knob 87 is pulled rearward within the window hole 36, the conversion lever 88 retracts the ratchet lever 8 against the tension spring 81 acting thereon to the position shown in two-dot chain diagram in FIG. The position of this ratchet lever 8 is such that the tip 82 of the skeleton lever is removed from the ratchet wheel 51 of the cassette, so that even if the handle 2 is pushed down, the ratchet lever 8 moves behind the ratchet wheel 51 by the conversion lever 88. Therefore, the release tape C cannot be pulled out from the cassette 4. In other words, only the punch shaft 5 is lowered.

In order to lock the actuating plate 85 in the front position or the rear position of the window hole 36, a deeper groove is formed in the central portion 110 directly below the first actuating plate, and the trailing plate 86 with the wart is inserted into the groove.
is fitted, and the wart of the companion plate 86 is elastically depressed into one of the two front and rear holes drilled in the actuating plate 85.

Therefore, when the actuating plate 85 is slid with the knob 87, the wart that has fallen into either of the holes will come out against its own elasticity, allowing the actuating plate 85 to slide, and then It falls into the other hole and locks the actuating plate 85 in that position.

Functions and Effects of the Invention The document bunch 1 of the present invention has the above-described structure, and in particular, the document holding mechanism 6 normally rises slightly from the front half 11 of the base, and a document person can insert the document underneath. Although it does not get in the way, when the handle 2 is pushed down to make a hole, the document A is immediately pressed onto the front half 11 at a position close to the hole, so that the reinforcing piece B can be attached smoothly. Moreover, even if the document A is made of flexible paper, the reinforcing piece B can be beautifully stuck to the predetermined position of the document A, making it possible to create an excellent document punch.
