Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is for supply during reinforcement for a document punch in which a reinforcing piece is attached to the hole position immediately before punching a binding hole in a document. It is placed between tape cassettes/cassettes.

[Traditional branch! , #i1 ``To reinforce the periphery of the binding hole drilled in 34f+.

Attach a reinforcing piece such as a thin plastic piece to the hole location of the document in advance, and then attach it to the JJ along with this reinforcing piece.
Document punches for punching holes in documents are already known.

In such document punching, it is desirable to freely attach a tape cassette containing a reinforcing piece tape to which a reinforcing piece is attached, and to send out the reinforcing piece from this tape cassette in conjunction with the punching operation. When attaching the tape cassette to the document punch, if the small hole for feeding the tape made in the tape is not in a position that exactly matches the reinforcing piece feeding mechanism of the document punch, the reinforcement may not be accurate. It is not possible to send out one piece.

In particular, when the tape cassette is not attached to the document punch, or when it is attached but the reinforcing piece tape freely moves in and out of the tape cassette when the handle is returned, etc., the reinforcing piece is sent out in rhythm with the handle. Accurate delivery of the reinforcing piece cannot be expected due to the operation of the mechanism.

In a document punch having a structure in which a reinforcing piece feeding mechanism is built into a tape cassette, this distance m can be relatively easily calculated by the company because the reinforcing piece feeding mechanism can hold the tape. However, in this case, each time the cassette is replaced with a new one, the reinforcing piece delivery mechanism must be discarded together with the cassette, resulting in an increase in cost.

[Problems to be Solved by the Invention] The present invention prevents the reinforcing piece tape from freely moving in and out of the tape cassette when the tape cassette is not attached to the document punch, or when the tape cassette is attached but the handle is returned to its original position. In addition, when attaching the tape cassette to a document punch, make sure that the reinforcing strip tape is properly aligned so that the small hole for tape feeding provided in the reinforcing strip tape always fits correctly with the reinforcing strip feeding mechanism of the document punch. To provide a document punch in which the position of a small hole for feeding a tape is restricted, and the restriction is released when a reinforcing piece is delivered to a punching position by a reinforcing piece sending mechanism linked to a handle. , which is the problem we are trying to solve.

[Means for Solving the Problems] In the present invention, in the document punch which feeds the reinforcing piece from the tape cassette described above, the tape cassette is connected to a storage part for storing the reinforcing piece tape and from the storage part. A reinforcing piece is composed of a beak part for leading out the tape, and the beak part has a lead-out passage for leading out the tape along the inner wall, and a lead-out passage for leading out the tape along the inner wall; An in-hole passage for guiding along the surface and a reinforcing piece outlet opened in the folded plate part of the tape are provided, and the guide passage has a 1 m li diameter extending from the inner wall side into the guide passage.
- is provided at the free end of the bullet to be locked to a small tape feeding treasure provided on the reinforcing strip tape, and the bullet is attached to the small hole and the reinforcing strip delivery mechanism when assembled into a document punch. It has a protruding locking protrusion that escapes from the small hole.

[Function] When the tape cassette is not attached to the document punch, the locking protrusion provided on the bullet piece protruding into the tape guide path locks into the feeding hole of the reinforcing piece tape, and the reinforcing piece tape Since the position of the feeding small hole is restricted, the reinforcing piece tape and the cassette are maintained at a predetermined rA engagement position.

When the tape cassette/door is assembled into the document punch, the locking protrusion matches the reinforcing piece delivery mechanism of the document punch, the ring 1 protrusion is pulled out from the small hole, and the small hole engages with the reinforcing piece sending mechanism. The reinforcing piece tape built into the cassette is reliably delivered by a reinforcing piece sending mechanism that is linked to handle operation. Tape cassette to document punch J, Jt
In the state in which the reinforcing piece tape is attached, the above-mentioned state in which the reinforcing piece tape is locked to the reinforcing piece sending mechanism is maintained.

When the tape cassette is removed from the document punch, the latches and protrusions are again locked in the small holes by the force of the bullet, so even if the cassette is removed, the relative position between the cassette and the reinforcing piece tape does not change.

[Embodiment] Figures 1 to 3 show an embodiment of the tape cassette for document punching of the great invention. The tape cassette l attached to the document punch 20 shown in FIG.

A lower reinforcing piece outlet 10 for sending out the reinforcing piece B is provided between the inner wall 7 and the lower reinforcing piece B.

As shown in FIG. 1, the middle wall 7 and the lower wall 8 are curved in an arc shape, and the middle wall 7 has grooves 12 on both sides of the curved portion. By providing L'2, a bullet piece 13 is provided that projects into the guide path 8, and at the free end of the bullet piece 13, a small hole for feeding the tape provided in the reinforcing piece tape has a hole of 4Jh.
+h locking protrusion 14 is provided.

As shown in FIG. 2, the lower wall 9 protrudes by a small width on both the left and right sides of the beak portion 3, and the middle wall 7 also has the above-mentioned cut f,! !
12. The part below where the bullet piece 13 is separated by 12 is a projecting edge having the same width as the lower wall 3, but the lower end part is widened to guide the feeding of the tape C.

At the tip of the beak portion 3, the upper wall 5 and middle wall 7 protrude slightly from the lower wall 9, so that when the cassette l is assembled into the base 21 of the punch 20, which will be described later, the tip of the beak portion 3 is The reinforcing piece B that comes to cover the edge of the document A inserted into the punch 20 and is sent out from the tip of the beak part 3 will surely cover the edge of the document A.
(See Figure 5).

As shown in FIG. 1, the reinforcing piece tape is stored in the cassette 1 in a wound state, and its tip passes through the lead-out passage 8 and is folded back 180' at the tip of the inner wall 7, with a small hole in the guide passage 8. By locking the 1F protrusion 14 in the circle, it maintains a predetermined relative position with the cassette 1, and when the released release tape C is folded back at the folding part, the reinforcing piece B is automatically removed from the tape. Peel it off and send it for reinforcement! It is sent from O onto document A.

4 to 6 show a document punch for punching a binding hole with a reinforcing piece attached to one side of a document A by incorporating the above-mentioned cassette L. It is provided with a punching mechanism for punching holes in a document, and a reinforcing piece sending mechanism for sending out a reinforcing piece B to a document A immediately before punching the holes.

The document punch 20 includes a base 21, a handle 22,
A cassette 1 is provided with a pair of left and right support plates 23 for attaching the handle 22 to a base 21, and a cassette 1 containing a release tape C to which a reinforcing piece B is attached can be mounted on the base 21. 'X unit 2! As can be seen from FIG. 4 and other figures, it is made of plastic and has a rectangular plane and shape, and is provided with recesses 25, 25 in its rear half for incorporating the cassette 1.

The metal base plate 27 stretched over the front half of the base also covers the central part, which is slightly higher than the front half, and the vertical part 28 (see Fig. 6) formed in the stepped part allows the hole M to be drilled.
Specifies the insertion position for Class A.

In the handle 22, a support shaft 30 inserted therein is supported by a bearing 34 formed by a cut groove in the front end of the vertical portion 32 of the left and right support plates 23.23, and a linear spring wound around the support shaft 30 is supported. (not shown), the free end of the handle 22 is always raised to a specific height. In addition, the handle 22
A pin 39 attached to a punch shaft 38 that is movable up and down on the support plate 23 is inserted into a through hole 36 located slightly away from the support shaft 30 toward the tip of the nozzle. This 1'r through hole 3
B has an arc shape centered on the support shaft 30, and its length is the length at which the ratchet lever 40, which will be described below, rotates the dismounter 44 with the claw 42 at its tip in order to send out the reinforcing piece. It is.

The ratchet lever 40 is attached so that it can rotate freely around the handle 22, and when the handle 22 is pushed down, the ratchet lever 42 at the far end rotates the pawl 44 by the l portion. This alighting car 44 has a roller 46 having small protrusions 47 protruding at regular intervals that engage with small holes for feeding the tape.
are integrally provided, and as the roller 46 rotates, the small protrusions 47 pull out a specific length of the η chick tape C from the cassette 1. In this case, the small protrusions 47. It goes without saying that the spacing between... matches the spacing between the small holes on the reinforcing piece tape.

Further, the reinforcing piece sending mechanism constituted by the roller 4B, the windmill 44, etc., engages the leaf spring 50 with the claw of a large windmill 48 provided integrally with the reinforcing piece sending mechanism. This prevents reverse rotation.

The recess 25 formed in the base 21 has a locking groove 5 in the bottom wall.
2, the cassette l has a structure in which the tip of the lower wall 8 of the beak portion 3 abuts against the vertical portion 28 of the metal base plate 27, and the protrusion 16 on the bottom wall is engaged with the locking groove 52. , the installation position to the base 21 is determined, and the beak portion 3 is thereby determined.
The tip protrudes from the window hole 55 onto the front half (Fig. 5).

When the roller 4B is assembled on the tape cassette lt-base 21, one of the small protrusions 47 collides and presses the locking protrusion 14 of the cassette 1, resisting the elasticity of the elastic piece 13. When pushed out from the small hole, the small protrusion 47 is fitted into the small hole, and the small protrusion 47 is installed so as to pass through the guide passage 8 by rotation of the roller 46. Therefore, when the cassette (1) is installed at a predetermined position on the base 21, the small protrusions 47 of the roller 46 fit into the small holes in the tape, and the tape is set in a state where it can be fed out.

The reference numeral 60 in Fig. 5.6 indicates that the reinforcing piece B sent out onto the document A is inserted into the document A before the punch shaft 38 punches the binding hole in the document.
The suppression mechanism that presses on A to firmly adhere it is shown.
A detailed explanation thereof will be omitted.

Next, the operation of the document punch described above will be explained.

The 411 strong shore cheep is built into the tape cassette l with its tip passing through the passage 6.8 and the locking protrusion 14 being locked in the small 'fD.

Insert this cassette 1 into the recess 25 of the base 21, bring the tip of the lower v: 9 into contact with the vertical portion 28, and engage the protrusion 1B in the engagement groove 52, then the roller When one of the small protrusions 47 of 46 collides with the locking protrusion 14 and presses against the elasticity of the tar piece 13, the locking protrusion 14 is pulled out of the small hole and the small protrusion of the roller 46 is pressed. 47 is engaged in the small hole, and the small protrusion 47 projects into the guide passage a. Therefore, by loading the cassette 1 into the document punch 20, the release tape C becomes ready to be fed a predetermined length by the reinforcing piece feeding mechanism.

When the handle 22 is pushed down with this ik K, the pawl 42 of the ratchet lever 40 rotates the alighter 44, so the roller 46 integrated with this rotates by one pawl of the alighter 44, and the small hole D +, m The protruding protrusion 47 pulls out the tape by one reinforcing piece and sends out the reinforcing piece B onto the document, and the nokunna shaft 38 that descends by operating the handle separates the reinforcing piece B into type 3 A. In this case, the roller 46 is drawn to the locking protrusion 14 with the next small protrusion 47 engaged with the small hole by the rotation of the single claw wheel 44 by one claw, and the primary tape is made. Prepare for shipping.

When the cassette 1 is removed from the base 21, the locking protrusion 14 that was pressed by the small protrusion 47 is relatched to the small hole in the tape by the elasticity of the bullet piece 13, so that the cassette 1 is removed from the base 21. Even if the reinforcing piece tape is removed from the cassette 1, the relative position between the reinforcing piece tape and the cassette 1 does not change.

[Effects of the Invention] The tape cassette of TI Ming is provided with a locking protrusion that locks into the small hole of the reinforcing piece tape and escapes from the small hole by the reinforcing piece feeding mechanism of the document punch, so that the reinforcing piece of the document punch can not be fed out. The reinforcing piece can be reliably delivered in synchronization with the mechanism. Furthermore, since the cassette itself is not provided with a reinforcing piece delivery mechanism, it can be made cheaper than a cassette that is equipped with this mechanism.
