Description

[Detailed Description of the Invention] Purpose of the Invention The present invention provides a reinforcing piece for reinforcing the periphery of the through-hole in a punch that makes a through-hole with a diameter of approximately 6% on one side of a document in order to insert the document. The hole punch shaft of a punch that has a mechanism for pasting is equipped with a mechanism that presses the document from above the reinforcing piece attached to the document, and the hole is punched while pressing both the document and the reinforcing piece. This paper relates to an improved document punch.

Industrial Application Fields and Prior Art In documents where several holes are made on one side of a document and the document is inserted into a notebook such as a loose-leaf paper through the holes, the area around the holes tends to tear. However, in order to strengthen the area around the hole, a reinforcing piece such as a thin plastic piece is pasted on the part of the document where the hole is to be punched, and then the punch is punched together with the reinforcing piece to make the hole in the document. is already known. (Jikko 56-46718,
(Refer to Japanese Utility Model Application No. 56-58799 and Japanese Utility Model Application No. 57-45998) Problems to be Solved by the Invention However, these conventional methods simply place a reinforcing piece on the document and do not press it onto the document. The tendency of the hole punch shaft to pull at the document as it enters the through-hole on the underside of the document can cause the document to wrinkle, or the reinforcing strip to curl over the document, even if the reinforcing strip is once stuck. It had the disadvantage that it separated from the document and could not be used to make beautiful holes.

Means for Solving the Problems In order to solve the drawbacks of the conventional hole punch equipped with a reinforcing piece pasting mechanism, the present invention provides a base on which a document can be placed while passing the punch shaft through the hole punch shaft. A device for pressing the top is provided, and the pressing device has a pressing plate on the lower side and a pressing plate on the upper side sandwiching the sleeve part of the seat plate attached to the center part of the base, and the pressing plate has the punch on the pressing plate. A bullet plate mechanism that locks onto a shaft and rises as the punch shaft rises; and a resilient mechanism that is pressed by the punch shaft when the punch shaft descends and exerts a downward action on the pressing device. Thus, the bullet plate mechanism holds the pressing device in a predetermined raised position even during the initial descent of the punch shaft to allow the operation of pasting the reinforcing piece to the document, and immediately after the pasting operation is completed. As the punch shaft continues to descend, the pressing device presses the document together with the reinforcing piece onto the base by the action of the resilient mechanism, and continues the pressing action so that holes are punched in both the reinforcing piece and the document. As a result, the reinforcing piece is firmly pressed against the document, and the reinforcing piece does not warp or wrinkle the document at all, making it possible to create a document punch that punches beautiful holes.

Example Figure 1 shows document A placed on one side of document A/-
An example is shown in which a pair of through-holes A1 and A2 are drilled for inserting the paper into a three-dimensional book, and reinforcing pieces B and B for reinforcing the periphery of the hole are pasted to the holes AI and A2. An example is shown in which through holes A1 and A2 are also formed in piece B. However, the purpose of the present invention described below is not limited to drilling such a pair of holes AI and A2, and even when drilling a single hole, or five or four holes, this It goes without saying that this is within the technical scope of the invention.

Figure 2 shows a pair of holes A1 and A2 on one side of document A in Figure 1.
This figure shows an example of a punch 1 that can simultaneously open the holes with one handle operation. ,
It consists of a cassette 4 containing a tape C (see Fig. 7) to which a reinforcing piece B is attached.

As can be seen in FIG. 3, the right half of the base 10, that is, the front half 11, is formed to be about three times higher than the rear half 12, and the front half 11 makes holes A1 and A2 in the document A. The rear part 12 has a mechanism for opening the cassette 4.
It has a low platform shape to facilitate the operation of assembling it into or taking it out from the base 1o.

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

The rear half part 11o of the front half part 11 of the base (hereinafter referred to as the center part 110 of the base) has a length approximately μ of the length of the base 100 in the front-rear direction, and the height of this part 110 is greater than that of the front half part. 11
It is several percent (about 5%) 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 51.5 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 upright on its left and right ends, which has a length that reaches the front end of the sleeve portion 31 and has a height about the same as the height of the central portion 110. Support plate 6.3
The upper sides 32 of each are 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 shaft 5 has its midsection attached to a pin 20 horizontally suspended on the handle 2 so that it can move up and down through the guide hole 35, the through hole 34. It is installed through the base, especially the front half of the base 11.
For the through-holes 14 on the top surface, in order to beautifully drill the holes A1 and A2 in the document A, a metal plate 13 with the through-holes 14 is used, and the metal plate 13 is stretched over the front half 11 of the base. be. The inside of the front half of the base 11 is hollow, and pieces of paper from which holes AI and A2 have been punched are collected in the hollow, and can be taken out as needed.

The handle 2 has the same width as the base 10 and a somewhat shorter length, 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 an n-shaped vertical cross section and is large enough to allow the upper side 32 of the support plate 3 to be loosely inserted therein, and the handle base 21 has an n-shaped longitudinal section that allows the upper side 32 of the support plate 3 to be loosely inserted therein. At a location overlapping the front end, it is supported by a support shaft 22 that horizontally passes through the handle root 21 and the front end of the support plate 3, 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 25 of the handle 2 to a certain height above the base 10, a spring is wound around the support shaft 22, and the resilient end 24,24 of the spring is connected to the top of the seat plate 30 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 21 of the handle 2.
It is suspended horizontally on the handle 2 at a far rear position, and that position is also at the rear of the support shaft 22. When the free end 23 of the handle in the raised position is pushed down, the pin 20 descends while drawing an arc-shaped trajectory with the support shaft 22 as the fulcrum, so the pin 20 is vertically moved so as not to hinder its movement. A long hole is drilled in the support plate 3 (not shown), and the pin 20 crosses the inside of the long 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 be raised and lowered along 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. The punch shaft 5 is formed with a fork or a through hole, and is K-shaped so that the punch shaft 5 can move up and down as shown in FIG. A leaf spring 65 having hairpin-like elasticity that acts to constantly press the bent portion 61 against the upper side 51 of the support plate is installed so as to pinch the bent portion 61 and the upper side 52 of the support plate. Therefore, the elastic force of the leaf spring 65 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 has a length that does not interfere with the descent of the bottle 20 when the handle 2 is pushed down to make a hole in the document A, but when the hole is completed and the push-down blade to the handle 2 is pressed down. When released, the handle 2 automatically rises due to the spring force 24, and just before returning to its uppermost position, the vertical hole 6 opens.
When the handle 2 returns to the uppermost position, the presser plate 6 is also slightly raised by the bottle 20 against the elasticity of the leaf spring 65, as shown in FIG. The length of the lower end of the presser plate 6 is set at 5 so that it rises by several percent from the top of the front half 11 of the base.

As described above, when the document punch 1 is not in use, the document holding mechanism 6 has the handle 2 raised to its uppermost position, and at the same time, the holding plate 6 is also in the raised position, so that the document holding mechanism 6 cannot be moved onto the front half 11 of the base. There is no problem in inserting document A. When the handle 2 is pushed down to open the AIC holes A1 and A2 of the inserted document, the bin 20 instantly opens the vertical holes 6.
Since it descends from the lower end of 0, the press plate 6 immediately descends by the leaf spring 65 and presses the document A onto the front half 11 of the base. This prevents the movement of document A that tends to occur when attaching reinforcing piece B, or the occurrence of wrinkles on document A, and ensures that reinforcing piece B is attached to document A in its designated position. It has the characteristic of being shy.

In order to prevent the presser plate 6 from unnecessarily rising above the support plate 3, a small protrusion 67 is provided on the side surface of the support plate 3, and 5K is provided so that the presser plate 60 steps collide with it.

Even if the reinforcing piece B is pasted at a predetermined position on the document A and a hole is punched into the document along with the reinforcing piece B with the punch shaft 5, the reinforcing piece B does not necessarily stick firmly to the document AK. After the reinforcing piece B is stuck to the predetermined position of the document A, the document A is also attached to the front half of the base 1 from above the reinforcing piece B.
A mechanism 7 is provided for drilling a hole while pressing down on 1. (See Figure 3.5) The mechanism 7 has a pressing plate 70 with just the right width to press down the reinforcing piece B, facing the lower side of the sleeve portion S1 of the seat plate 30, and The part that extends to the sleeve part 31 is bent upward at the front end of the sleeve part 31, and then bent horizontally above the sleeve part 31, leaving a considerable distance from the upper surface of the sleeve part 31, to form the press operation plate 71. , the rear end of the actuating plate 71 extends to above k of the seat plate 30. The pressing plate 70 and the pressing operation plate 71 both have a hole 7 through which the punch shaft 5 passes.
2.73, and therefore the pressing plate 7o 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 pressing 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 operating plate 71.
is attached, and the tip of the chain plate spring 74 elastically extends in the direction of the punch shaft 5 and engages on the pin 2°. Thus, the pressing plate 71, and therefore the pressing plate 70, is constantly raised by the leaf spring 74 when the handle 2 is in the raised position, and at this time, the document A is inserted onto the front half of the base 11 to the predetermined drilling position. can be done.

A helical spring 75 is wound around the punch shaft 5 above the pressing operation plate 71, but the upper end of the spring 75 does not normally act on the bottle 20 (ie, when the handle 2 is raised).

In the mechanism 7 described above, when the handle 2 is pushed down to make a hole in the document AK, the document holding mechanism 6 first descends and presses the document A onto the front half of the base 11 as described above.

At this time, although the bottle 20 descends somewhat, the leaf spring 74 engaged with the bottle 20 only slightly weakens its elastic force and still presses the pressing plate 70 against the back side of the sleeve portion 51.

In this way, when the handle 2 is pressed down, one sheet of the reinforcing piece B is moved from the cassette 4 assembled into the base 10 to the document A while the pressing 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 bottle 20 will be lowered as the bottle 20 is lowered, and only then will the pressing plate 71 be lowered, which means that the pressing plate 70 will be lowered onto the front half 11 of the base. I'll put it on. In this way, the pressing plate 70 presses down the reinforcing piece B to which the document AK is attached.

Since the subsequent depression of the handle 2 further lowers the bottle 20, the bottle 20 now compresses the coiled spring 75 on the pressure actuating plate 71, and thus the spring force 75 causes the pressure plate 70 to be strongly pushed forward. 11 to firmly press the reinforcing piece B onto the documents A&C.

Also, when in such a crimped state, the punch shaft 5
descends and, together with the reinforcing piece B, opens the document AK holes A1 and A2. (See Figure 5) The cassette 4, which is used to feed out one reinforcing piece B by pressing down the handle 201 times, is a plastic container with a snail-shaped side surface, as seen in Figure 6.7.8. 40, and its width 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 rattling 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 here, 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 tape delivery chamber 41 connected to the side surface of the container 40 is provided with a mechanism for feeding out the tape C from a cassette container 40 in which the release tape C is wound up and stored.

The tape C feeding mechanism is made up of a tape feeding row 250 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 the circumferential surface of the roller 50. On both left and right end surfaces of the roller 50, there are ratchet wheels 51 and 51 that protrude outward from the wall of the delivery chamber 41. The short shaft 52 is engaged with a bearing plate 42 protruding from the tape delivery chamber 41, and the roller 50 is supported at 5 so as to be rotatable in the tape delivery chamber 41. For this reason, it goes without saying that there are holes 45 in both left and right walls of the tape delivery chamber 41 through which the ratchet wheel 51 can rotate. (See Figure 2.5) The center line VcG of the circumferential surface of the tape feed roller 50 is
The small protrusions 53 are provided at specific intervals.

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.

In order to ensure that the small hole B2 of the tape C is engaged with the small protrusion 53 of the roller 50 and that the tape C is reliably fed out when the roller 50 rotates, it is necessary to approach the circumferential surface of the roller 50. The tape guide plate 43 is provided so as to protrude from the left and right side walls of the delivery chamber 41 so as not to obstruct the rotation of the small protrusion 53 of the row 250. The guide plate 43 is 5K 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 CK at its adhesive surface B1, and the release tape C is wound up and stored in the container 40 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 43.
Subsequently, it is provided above the delivery chamber 41, and its tip protrudes from the delivery chamber 41 by several χ. Furthermore, this folding plate 4
As shown in the figure, the tape C is rapidly folded back and runs at the tip 5, so a considerable repulsion force is required during the run. Therefore, if one side wall of the tape delivery chamber 41 is made 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 indiscriminately, and the tape delivery end of the cover plate 47 protrudes from the delivery chamber 41 by several χ to form a tape delivery port. 44 is formed.

Slightly long concave grooves 54 of a specific length are provided on both left and right end surfaces of the tape feed roller 50 at positions close to the circumferential edge of the roller 50 and at the same spacing as the pawls of the ratchet wheel 51.

This is shown in dotted lines in FIG. A companion plate 48 having a protrusion 49 inserted into the groove 54 & C is provided by cutting and raising the wall plates on both the left and right sides of the delivery chamber 41. The guide plate 4B normally protrudes to both left and right sides of the delivery chamber 41 as shown in the figure, and therefore the protrusion 49 protrudes from the groove 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 roller 50.

The same number of stop grooves 55 as the small protrusions 53 are provided, and the wave grooves 5.5
A spring mold 56 that is depressed upward is 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 row 250 from the circumferential 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 One is for cutting the tape C and the other is for cutting the tape C with saw teeth 58.

As can be seen in FIG.
The tape is pulled out from the tape outlet 44, and the folding plate 45 is
Then turn the guide plate 43 and roller 50 suddenly downward.
It passes through the gap and sends 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 hole punch 1 as shown in FIG. 2, the punch base rear half 12 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 made low enough that the ratchet wheel 51 of the cassette 4 does not touch it, and the cassette 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 base front half 11 has a vertical wall 17 slightly behind the punch shaft 5, and the wall 17 is adapted 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 adhere beautifully to documents A & C.

A ratchet lever 8 is attached to the handle 2, which locks the ratchet wheel 511'C of the cassette 4 assembled in the punch 1 and causes the ratchet wheel 51 to rotate one pawl each time the handle 2 is pushed down. A portion of the lever '8 is inserted into a cut groove 35 formed on the rear edge of the seat plate 30, and slides within the cut groove 55. 25, and can freely rotate about the pivot 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 is always biased to press a portion of it into the deep part of the cut groove 35. has been done.

The free end (tip) 82 of the ratchet lever 8 has a ratchet wheel 51.
When the handle 2 is in the raised position, the ratchet wheel 51 is bent into a hook shape so that it can be easily engaged with the pawl of the handle 2, as shown in the one-dot chain diagram in FIG.
Its tip 82 is always exposed to one of the claws. Also, the sliding side that fits into the cut groove 55kC of the lever 8 has a specially shaped cam 8.
Therefore, when the handle 2 is pushed down to the position shown in chain lines as shown in FIG. is turned in the direction of the arrow. However, the ratchet wheel 51 is part 1.
When the pawl is turned, the lever tip 82 immediately comes off the pawl 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 where the ratchet lever tip 82 acts on the ratchet wheel 51 is located at the side of the cassette 4 in which the base groove 15Vc is incorporated. This is the inner side of punch 1. However, the cassette 4 has ratchet wheels 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 ratchet wheel 51,
The tip 82 is connected to the outer plate 48 protruding from the side of the cassette 4.
(See Figure 7) so that it is flush with the side wall of the cassette 4.
(See Figure 4).

At this time, the protrusion 49 on the outer plate 48 enters the groove 54 of the tape feed roller 50, and even if the handle 2 is pushed down forcefully, the roller 5o only rotates within the range of the groove 54 into which the protrusion 49 has entered. do not have.

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 mechanism 55, 56 of this row 250 is
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 ratchet wheel 51 to prevent the ratchet wheel 51 from rotating in the reverse direction.

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. Appropriate cutting can be performed using a serrated cutting blade provided at the outlet.

The reinforcing piece B may not necessarily need to be attached to the document A. In that case, the cassette 4 can be removed from the punch 1, but the punch IK is provided with a VC mechanism to prevent the reinforcing piece B from coming out of the cassette 4 even after the cassette 4 is assembled.

As shown in FIG. 3, a shallow groove is provided on the top surface of the central portion 110 on the lower side of the seat plate 30 mounted on the punch central portion 110, and an actuating plate slides in the corrugated groove. 85, and a knob 87 that protrudes upward from a part of the actuating plate 85.
The rear part of the actuating plate 85 is placed between the left and right sides of the central part 110 as shown in FIG. In this case, there is no conversion lever 88 which is slightly protruded into the cavity into which the cassette 4 is inserted and abuts against the cam 80 of the ratchet lever 8.

In this configuration, when the knob 87 is pulled back inside the window hole 36, the conversion lever 8B causes the ratchet lever 8 to retreat to the position shown by the two-dot chain diagram in FIG. 3 against the tension spring 81 acting thereon. The position of this ratchet lever 8 is such that the tip 82 of the 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 56, a deeper groove is formed in the central portion 110 directly below the actuating plate, and the trailing plate 86 has a groove in 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 the wart will no longer be present. It falls into one hole and locks the actuating plate 85 in that position.

Functions and Effects of the Invention The document punch of the present invention has the above-described structure, and in particular, the mechanism 7 for pressing the document A onto the base together with the reinforcing piece B is connected to the seat plate 3 mounted on the central portion 110 of the base. It consists of a lower pressing plate 70 and an upper pressing actuating plate 71 that sandwich the sleeve portion 31 of the cough presser vertically, and is elastically locked to the pin 20 of the punch shaft 5 by a plate spring 74 attached to the cough pressing actuating plate. Since it is made to rise, the punch shaft 5 for drilling holes
In the initial downward movement, the elasticity of the leaf spring 740 is only weakened, and the pressing plate 70 is still in contact with the lower surface of the sleeve portion 31.
Therefore, during the short period when the pressing plate 70 is rising from the front half 11 of the base, the reinforcing piece B is pasted onto the document A, and then the pressing operation is moved onto the document A.
Therefore, the pressing action on the reinforcing piece B becomes reliable, and an excellent reinforcing piece pressing device that can reliably punch a hole in the document A to which the reinforcing piece B is attached can be obtained.
