Description

[Detailed Description of the Invention] Purpose of the Invention The present invention provides a punch for punching a through hole of approximately 6χ in diameter on one side of a document in order to insert the document, and the purpose of the present invention is to reinforce the through hole punched in the document so that the through hole is easily torn. Therefore, just before drilling the through hole, attach a reinforcing piece to the document.
Thereafter, a tape to which the reinforcing piece is attached for supplying the reinforcing piece is stored in a punch equipped with a mechanism for making a through hole in the document together with the reinforcing piece, and can be easily installed and removed from the punch. This paper relates to improvements to such cassettes.

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 notebook such as a loose-leaf paper through the holes,
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 piece of plastic is pasted on the area of the document where the hole is to be punched.
Punches are already known which are subsequently used to punch holes in documents together with the reinforcing piece. (Jikko 5
1-46718, Utility Model 56-58799, Utility Model 57
-45999) Also, attach the reinforcing piece to a release tape, wind up the release tape in a cassette (W), insert the cassette container into a hole punch, and remove the release tape from the cassette each time you punch a hole in a document. A device that can be rolled out to attach a reinforcing piece to a document has already been proposed. (Jitsukai 57-15
3500, 57-45998) Problems to be Solved by the Invention However, in those conventional methods, a release tape with a reinforcing piece attached is incorporated into the cassette, and the incorporated tape is used to feed the tape of the cassette. It was difficult to adjust whether or not the reinforcing piece was reliably wound around the roller, and it was also difficult to make adjustments for feeding out the reinforcing piece after the cassette was assembled into the punch.

Means for Solving the Problems The present invention solves the drawbacks of the reinforcing piece pasting tape storage cassette incorporated into a hole punch equipped with such a conventional reinforcing piece pasting mechanism.
A ratchet lever for feeding out the reinforcing piece adhesive tape was attached to a 71-inch needle equipped with a hole punch shaft that was constantly elevated above the base at a specific height, and the tip of the lever was incorporated into the base. The cassette containing the reinforcing piece adhesion tape is placed facing the reinforcing piece adhesion tape feeding ratchet wheel, and the ratchet wheel is rotated by one pawl when the handle is lowered and inserted directly under the punch shaft. In a document punch that is equipped with a mechanism for attaching the reinforcing piece to a document immediately before punching a hole for document binding in the document, a cassette containing a reinforcing piece adhesion tape to be incorporated into a predetermined position of the base is configured to attach the reinforcing piece to the document just before punching a hole for document binding in the document. A tape feeding chamber for incorporating a mechanism for feeding out the tape is provided protruding from a portion that stores the tape, and the tape feeding chamber is provided with a tape feeding roller that feeds out the tape from the tape storage portion. The cassette is characterized in that a ratchet wheel that engages with the ratchet lever is provided on the left and right end surfaces, and that the ratchet wheel is made to protrude from the left and right side walls of the tape delivery chamber. Not only can it be installed freely in any of the grooves, but the ratchet wheel protrudes from the cassette, making it an excellent cassette that allows you to easily adjust the engagement between the tape inside the cassette and the tape delivery roller. It was possible to do this.

Embodiment Figure 1 shows a pair of through holes AI on one side of a document A for inserting the document A into a loose-leaf notebook.
, A2 is shown, reinforcing pieces B and B for reinforcing the periphery of the pattern hole are pasted to those holes AI and A2, and the reinforcing piece B
This shows an example in which through holes AI and A2 are also provided.

Figure 2 shows a pair of holes 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.The punch 1 consists of a base 10, a handle 2, and a pair of left and right support plates 5 to which the handle 2 is attached on the base 10. and 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 AI 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 operations such as incorporating it into the base 10 or taking it out.

A friction plate 90 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 slipping unnecessarily.

The rear portion 110 (hereinafter referred to as the center portion 110 of the base) of the front half of the base 11 has a length approximately μ of the length of the base 10 in the front-back direction, and the height of this portion 110 is greater than the front half. Part 11
This height difference is convenient for inserting the document A to be punched into the front half 11.

A seat plate 30 having the same width as the base 10 is attached to the flat top surface of the central portion 110, and the seat plate 30 has both sleeve portions 5, through which a pair of hole punch shafts 5.5 are passed, 51 is long and protrudes above the front half 11.

The seat plate 50 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 that is approximately the same as the height of the central portion 110. Support plate 3.3
The upper sides 32 are each bent horizontally inward of the base 1G, and a guide hole 33 for raising and lowering the punch shaft 5 is provided in the front part thereof.

The punch shaft 5 is attached to a pin 20 horizontally mounted on the nozzle 2 so that it can be moved up and down through the guide hole 33 and through holes 54 and 14 formed in the sleeve portion 31 of the seat plate and the front half 11 of the base. It is installed by penetrating the abdomen, especially the front half of the base 1.
1. With the through holes 14 on the top surface, holes A1 and A2 are formed on the document A.
In order to make the hole beautiful, a metal plate 13 with a common hole 14 is used, and the metal plate 15 is stretched over the front half 11 of the base. The interior of the front half of the base 11 is hollow, and pieces of paper with punched holes Ai and A2 are collected in the hollow so that they can be taken out as appropriate.

゛The handle 2 has the same width qr as the base 10 and a somewhat shorter length, but the base 21 is largely gouged out in the center, leaving the part necessary for supporting the punch shaft 5, and thus the base This is to make it easier to confirm the position of the document person inserted on the front half 11 of the stand.

The handle base 21 has a mouth-shaped vertical cross section that is large enough to allow the upper side 32 of the support plate 3 to be loosely inserted therein, and its lower end (or front end) IK is located close to the front end of the support plate 3. The overlapping portion 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 25 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, a spring is wound around and attached to the support shaft 22, and the resilient end 24 of the spring is connected to the top of the seat plate 30 and the handle. It acts on the inner surface of 2. 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 slightly rearward than the handle 2 , and that position is also at the rear of the support shaft 22 .

The pin 20 is then attached to the handle free end 23 in the raised position.
When pressed down, the support plate 3 descends in an arcuate trajectory with the support shaft 22 as the fulcrum, so a long vertical hole is drilled in the support plate 3 (not shown) to prevent this movement from being hindered. ), the pin 20 crosses within the elongated hole. Therefore, the elastic force 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 raising and lowering of the bin 20. The mechanism 6 is the 41st K.

It is made of a holding plate 6 with a rather wide width, and the holding plate 6 has a vertically long hole 60 in the center, and the vertically long hole 60 is inserted into the bottle 20.
is engaged with. Further, the presser plate 6 is provided to move up and down 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 become the edge K of the punch shaft 5. The punch shaft 5 is made into two prongs or has a through hole formed therein so that the punch shaft 5 can be moved up and down as shown in FIG. The bent part 61 is the upper side of the support plate 5211C
A leaf spring 65 having a hairpin-like elasticity and constantly acting to press the bent portion 61 and the upper side 32 of the support plate is incorporated so as to pinch the bent portion 61 and the upper side 32 of the support plate. Therefore, the elasticity of the plate 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 has a length that does not interfere with the descent of the bin 2o when pressing down on the handle 2 to make a document AK hole, but when the hole drilling is completed, the pressing blade on the handle 2 is released. Then, the handle 2 automatically rises due to the spring force 24, and just before returning to its uppermost position, the vertical hole 6 is opened.
The bottle 20 is made to abut against the upper end of o, and when the handle 2 returns to the uppermost position, the holding plate φ of the bottle 2o is also slightly raised against the elasticity of the leaf spring 65, as shown in FIG. The length of the lower end of the presser plate 6 is determined so that it rises by several χ from the top of the front half 11 of the base. - As mentioned above, when the 4i type bunch 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. There is no problem in inserting document A above.

When the handle 2 is pushed down to open the inserted hole MAk hole AI, A2, the bottle 20 instantly moves into the vertical hole 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 is a problem that tends to occur when attaching reinforcing piece B.
It has the characteristics of preventing the movement of iA or the occurrence of wrinkles on document A, and ensuring that the reinforcing piece B is attached to document A in its predetermined position in a beautiful manner. In order to prevent the presser plate 6 from rising unnecessarily, a small protrusion 67 is provided on the side surface of the support plate 3, and the steps of the presser plate 6 are made to abut against it.

(Refer to Figure 2.4) Even if the reinforcing piece B is stuck to the specified position on the document A and the punch shaft 5 punches a hole in the document A along with the reinforcing piece B, the reinforcing piece B will not necessarily firmly attach to the document A. It does not necessarily mean that it is attached to the After the reinforcing piece B is pasted at a predetermined position on the document A, a mechanism 7 is provided for making a hole while pressing the reinforcing piece B and the document A onto the front half 11 of the base.

(See Figure 3.4.5) The mechanism 7 has a pressing plate 7o with just the right width for pressing down the reinforcing piece B, facing the sleeve part of the seat plate 5o and the lower side of the seat plate 51. The part extending forward from 7o is bent upward at the front end of the sleeve part 51, and then the sleeve part 31 is folded upward.
The upper side of the sleeve portion 31 is bent horizontally at a considerable distance from the upper surface to form a suppression actuation plate 71, and the rear end of the actuation plate 71 extends above the seat plate 30. There is. The pressing plate 70 and the pressing operation plate 71 both have holes 72 and 73 through which the punch shaft 5 passes, so that the pressing plate 70 pushes the document A onto the front half 11 of the base from above the reinforcing piece B. can be pushed to.

In order to constantly raise and press the suppression plate 70 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 wire plate spring 74 elastically extends in the direction of the punch shaft 5 and engages on the bottle 20. Thus, the suppression plate 71, and therefore the suppression 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 11 of the base 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 act on the pin 20 normally, that is, 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 A, 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 pin 20 descends somewhat, the leaf spring 74 engaged with the pin 20 only slightly weakens its elastic force and still presses the pressing 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 installed in the base 10 during a short period of time before the suppression plate 70 is 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 pin 20 is lowered. Put it on top. In this way, the suppressing plate 70 presses down the reinforcing piece B stuck to the document A from above.

Since the subsequent depression of the handle 2 further lowers the bottle 20, the pin 2o now compresses the coiled 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 it upwards to firmly press the reinforcing piece B onto the document A.

In addition, when in such a crimped state, the punch shaft 5
descends and, together with reinforcing piece B, punches holes A1 and A2 in document AK. (Refer to Figure 5) The reinforcing piece adhesion tape storage cassette 4 for sending out one piece of reinforcing piece B by pressing down the handle 201 times is the sixth one.
．． 7.8.9 As can be seen in Figure 8, it has a plastic container 40 with a snail-shaped side surface, and its width is:
It 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 too much.

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 ~, the reinforcing piece B is made of a hard plastic thin plate. It has a circular shape, one side of which is an adhesive surface B1, and is stuck to the release tape C at specific intervals on the adhesive surface B1.

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.

Original tape storage container 4 in which the release tape C is wound up and stored.
A mechanism for feeding out the tape C from 0 is provided in a tape feeding chamber 41 connected to the side surface of the container 40. The feeding mechanism for the tape C is made up of a tape feeding roller 5o provided at the center of the feeding chamber 41, and the feeding roller 5o has the same width as the width of the feeding chamber 41. The tape C can be completely placed on the circumferential surface of the roller 50, and there are ratchet wheels 5, 51 on both left and right end surfaces of the roller 50 that protrude outward from the wall of the delivery chamber 41. The shaft 52 is locked to a bearing plate 42 protruding from the delivery chamber 41, and the roller 50
is rotatably supported in the tape delivery chamber 41.

For this reason, it goes without saying that holes 29 are provided in both left and right walls of the tape delivery chamber 41 through which the ratchet wheel 51 can rotate.

(See Figure 2.5) Small protrusions 53 are provided on the circumferential surface of the tape feed roller 50 at specific intervals along the center line of the circumferential surface.

The small protrusion 53 is attached to a release tape C that rests on the surface of the roller 50.
When the roller 5o rotates, the tape C is wound onto the roller 5o 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 always engaged with the small protrusion 53 of the row 250 and that the tape C is reliably delivered when the roller 5o rotates, it is made close to the circumferential surface of the row 250. A tape guide plate 43 is provided to protrude from the left and right side walls of the delivery chamber 41 at a distance of 5KL so as not to impede the rotation of the small protrusion 53 of the roller 5o. The guide plate 43 is located in the upper part of the delivery chamber 41, as shown in FIG.
The cover plate 47 provided on the upper side of the cover plate 47 is connected to the tape folding plate 45 provided below the outlet 44 at the front end, but the lower part ends at just enough to surround the semi-circumference of the roller 5o.

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 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, the tape C
It is necessary to sharply turn it downward. Therefore, the upper part of the tape guide plate 43 is provided to protrude into the feed-out chamber 41 so that the tape C can run along the upper side of the tape feed-out chamber 41, and the tape folding plate 45 follows the tape guide plate 43 to feed out the tape. It is provided above the chamber 41, and its tip is connected to the delivery chamber 4.
The species degree is made to stand out by 1 to several percent. It should be noted that, as shown in the figure, the tape C is rapidly folded back and travels on the tip of the folding plate 45, and therefore requires a considerable repulsion force during its travel. 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 a% to form a tape delivery port. 44 is formed.

Slightly longer grooves 54 are provided on both left and right end surfaces of the tape feed roller 5o at a position close to the circumferential edge of the roller 50 at the same spacing as the pawls of the ratchet wheel 51 and have a specific length.

This is shown by dotted lines in FIG.
A companion plate 48 having a protrusion 49 protruding into the chamber is provided by cutting and raising the wall plates on both the left and right sides of the delivery chamber 41.

The guide plate 48 normally protrudes to the left and right sides of the delivery chamber 41 as shown in the figure, and therefore the protrusion 49 protrudes from the groove 54. The roller 5o can therefore rotate freely, which allows the release tape C contained in the cassette 4 to be easily wound onto the feed roller 5o.

Further, on one side of the circumference of the tape feed roller 5o, there are provided anti-rotation grooves 55 in the same number as the small protrusions 53, which are deepest at the same position as the small protrusions 53. is provided to protrude upward from the lower side wall of the delivery chamber 41.

A separating piece 57 for separating the tape C sent by the tape feeding roller 5o from the circumferential surface of the roller 5o 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, rapidly turned downward by the folding plate 45, passed between the guide plate 43 and the roller 5o, 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 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 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 part 110 of the
has a cavity wide enough for this bearing plate 42 to pass through, and the seat plate 30 mounted on the central portion 110 is mounted at a height such that the tape delivery chamber 41 just fits into the bottom of the groove 15. The base front half 11 has a vertical wall 17 behind the punch shaft 5, and the vaginal wall 17 abuts 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. It is effective in preventing sagging at the bottom and making the reinforcing piece B stick beautifully to the document AK.

A ratchet lever 8 is attached to the nozzle 2, which locks the ratchet wheel 511C 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 55 formed on the rear edge of the seat plate 30, and slides within the cut groove 35. However, it can be freely rotated about the shaft 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.
It is urged by 5 to push it into the deep part of 5.

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. In addition, the sliding side that fits into the cut groove 35 of the lever 8 has a specially shaped cam 80.
Therefore, when the handle 2 is pushed down to the position shown in chain lines as shown in Fig. 1g4, the lever tip 82 engages with one pawl of the ratchet wheel 51, and with the subsequent depression of the handle 2, the ratchet wheel 51 moves to the position indicated by the arrow. turned in the direction. 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 cutting groove 55, and the end 82 of the ratchet lever is incorporated into the pawl 51, and the side that acts is incorporated into the base @15 in this example. This is the inner side of the bunch 1 of the cassette 4. However, the cassette 4 has claw straps 51 protruding from both left and right sides. Therefore, cassette 4 is bunch 1
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 pawl 51,
The tip 82 is connected to the trailing plate 4B protruding from the side surface 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 of the companion plate 4B enters into the concave groove 54 of the tape feed roller 50, and the handle 2 is pushed down forcefully. .

Also, when the roller 50 rotates with this restriction, q
- The resilient mold 56 falls into the reverse rotation prevention groove 55 of the roller 50 to prevent the reverse rotation of the roller 50 and prevent the tape C from being pulled back into the cassette 4. The reverse rotation mechanism 55, 56 of the roller 50 is such that when the handle 2 is released from the push-down operation and the handle 2 rapidly returns to the raised position by the spring 24, the ratchet lever tip 82 acts on the pawl 51 and This prevents the claw cap 51 from being reversed.

After the reinforcing piece B is peeled off and only the release tape C remains, it is sequentially sent out from the bunch 1 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 ode A. In that case, the cassette 4 may be removed from the bunch 1, but the bunch 1 is provided with a mechanism to prevent the reinforcing piece B from coming out from the cassette 4 even when the cassette 4 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 bunch central portion 110, and the actuating plate 85 slides in the corrugated groove. 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 50, and the rear part of the actuating plate 85 is placed on the left and right sides of the central part 110 as shown in FIG. There is no conversion V-bar 88 which 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 the ratchet lever 8 is such that the tip 82 of the lever is removed from the pawl flap 51 of the cassette, so that even if the handle 2 is pushed down, the ratchet lever 8 moves behind the pawl flap 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 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 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 reinforcing piece adhering chip storage cassette incorporated into the document punch of the present invention has the above-described configuration, and the roller 50 for feeding out the reinforcing piece B one by one has ratchet wheels 51 on both left and right ends thereof. Since the ratchet wheel 51 is made to protrude from the left and right side walls of the cassette, it is possible to check by operating the ratchet wheel 51 whether the tape C installed in the cassette 4 is reliably wound around the feed roller 50. The protrusion of the ratchet wheel 51 from the left and right side walls allows the cassette 4 to be freely inserted into either side of the left or right groove 15 of the document punch 1. It was possible to do this.

Note that the anti-rotation groove 55 of the feed roller 50 and the resilient type that falls into it not only accurately feeds each reinforcing piece B, but also act as a reaction force for the tape C wound and stored in the tape container 40. , the reinforcing piece B that has been sent out by the tape C is prevented from being pulled back into the cassette 4.
