Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention, when making a spelling hole in a document, sends a reinforcing label for reinforcing the peripheral edge of the hole to a predetermined position of the document and attaches it. The present invention relates to a tape feeding device for a document punch in which a spelling hole is then formed in a document together with its reinforcing label.

[Prior Art] When one or more spelling holes are formed on one side of a document and the document is spelled into a notebook such as a loose leaf through this hole, the peripheries of the holes are easily broken, so that it looks like a thin plastic piece. There is already known a document punch in which a different reinforcing label is pre-applied to the punched part of the document, and then a hole is punched in the document together with the reinforcing label. Whenever a sticking operation is performed and a hole is made in a document, the tape feeding device is operated in association with the hole making operation so that the tape is fed from the cassette to attach the reinforcing label to the document.

However, since the tape feeding device in the above-mentioned conventional document punch feeds the tape from the cassette by the roller which rotates in conjunction with the operation of the handle, the feeding device becomes large and the document punch is small and lightweight. I couldn't make it portable.

[Problems to be Solved by the Invention] According to the present invention, a tape feeding device is miniaturized by feeding a tape by a slider that reciprocates in association with the operation of a handle, thereby making it possible to carry a document punch in a compact and lightweight manner. It is the problem to be solved that the problem is solved.

[Means for Solving the Problems] The present invention includes a punch shaft for making a spelling hole in a document placed at a predetermined position on a base by operating a handle, and a large number of the shafts are attached to the base at regular intervals. Incorporate a cassette containing a tape having a reinforced label and a plurality of small holes for tape feeding opened at equal intervals with the label,
In the document punch, the tape is fed out from the cassette by the tape feeding device linked to the handle operation, and before the punch shaft makes the spelling hole in the document, the reinforcing label peeled from the tape is sent to the punching position in the document punch. The apparatus is provided with a slider that reciprocates the base for a length for delivering one reinforcing label by operating the handle and releasing the handle at the initial stage of the handle operation. The slider has a tip in the tape passage of the cassette. By providing the elastic piece located, by engaging the small hole, by projecting an engaging element that is pulled out from the engagement with the small hole by releasing the handle operation and engages with the next small hole, This is a solution to the above problems.

[Operation] When the cassette is assembled to the base, the engaging element projecting from the elastic piece of the slider engages with the small feeding hole of the tape contained in the cassette.

When the handle is operated, the slider reinforces the label 1 at the beginning of the handle operation before punching a document with the punch axis.
Since the slide slides for the length of feeding one sheet, the engaging element engaged with the small hole of the tape pulls out the tape from the cassette and the reinforcing label is sent to the hole punching position of the document. A spelling hole is drilled in.

When the operation of the handle is released, the slider returns to the original position, and the engaging element is pulled out from the engagement with the previous small hole and is engaged with the next small hole.

The reciprocating movement of the slider in the base requires a smaller space for feeding the reinforcing label than the rotation of the roller. Therefore, the tape feeding device is downsized, and the document punch is small and lightweight and portable. be able to.

A space for inserting document A is formed (see FIGS. 2 and 3).

When the document A is inserted through the insertion gap to a position where it comes into contact with the front supporting legs 26, 26 and the handle 4 is pushed down after the hole making position is determined by the side gauge 8, the horizontal portion of the engaging hole 42 of the pressing member 41 is pressed. Presses the protrusion 32 and swing lever 30,30
Since the slider 35 is swung about the shaft 31, the slider 35 slides by the distance of the small hole D, the engaging element 39 feeds the tape C, and the reinforcing label B is peeled from the tape C by this, and the document A
Jump up. In this case, since there is play between the punch shaft 45 and the pressing protrusion 72, in the initial stage of pushing down the handle,
The punch shaft 45 is supported by a weak spring 68 and does not descend.

When the pressing protrusion 72 presses down the punch shaft 45 by continuing to push down the handle, the label presser 6 is also moved down together with the punch shaft 45 by the urging force of the spring 68, so that the upper edge of the locking hole 58 is The ridge 65 is pressed to lower the label stopper 7 to a position where it abuts the base plate 24, and the reinforced label B that has jumped out collides with this label stopper and falls to a predetermined position on the document A, and then descends. The label retainer 6 presses the reinforcing label B against the document A on the base plate 24 to attach it. on the other hand,
The punch shaft 45 further descends along the long holes 60, 60 of the label retainer 6 while compressing the spring 68 by the pin 48, and the base plate 24
Create a spelling hole in the reinforcing label B and the document A in cooperation with the punch hole 47 of.

In this case, in the label retainer 6, the projections 63, 63 go over the notches 50, 50 and descend along the guides 51, 51 due to the expansion of the bullet pieces 62, 62, while the label stopper 7 has the locking recess 67. And small protrusions
Since the label presser 6 only slightly descends due to the engagement of 52, the projection 65 slides over the upper edge of the locking hole 58 by the elasticity of the elastic piece and the projection 66 slides in the sliding groove 59 when the label retainer 6 descends. Then
The label stopper 7 is immersed in the label retainer 6. Further, when the slider 35 stops, the protrusion 32 of the swing lever 30 is engaged with the engaging hole.
Since the pressing member 41 further descends from the horizontal portion of 42, it does not hinder the pushing down of the handle 4 after the slider is stopped.

When the pushing down of the handle 4 is released, the pushing member 41 and the handle 4 are raised by the urging force of the spring 43, so that the protrusions 32, 32 of the swing lever 30, 30 engage with the horizontal portions of the engaging holes 42, 42. Then, the engaging element 39 of the slider 35 is returned to the original state
And slides in the opposite direction by the distance of the small hole D and engages with the next small hole D at the return position. The feeding of the tape C and the withdrawal from the small hole D by the engaging element 39 are easy because the feeding side of the tape is a vertical surface and the opposite side is inclined forward and downward.

When the handle 4 is lifted, the punch shaft 45 is pressed by the pressing protrusion 72.
When the pressing force is released, the punch shaft 45 is raised by the spring 68, and the locking piece 71 is pushed by the pin 48 by the subsequent raising of the handle.
Since the punch shaft 45 and the label retainer 6 ascend, the projections 63, 63 cross over the support plate and are locked in the notches 50, 50 due to the expansion of the bullet pieces 62, 62, and the lower wall supports the support plate. The label stopper 7 returns to the original position where it comes into contact with 28, the label stopper 7 returns to the original state in which it descends from the label retainer 6 by the return of the label retainer, and prepares for the next handle operation.

In the above embodiment, when the cassette 5 is removed from the base 2, the punch shaft can be used to make a spelling hole in the document.

[Advantages of the Invention] In the tape feeding device of the present invention, the reinforcing label is fed from the tape contained in the cassette by the slider that reciprocates for the length for feeding one reinforcing label in association with the operation of the handle. The space of the feeding device can be reduced, and the document punch for attaching the reinforcing label to the document can be made small and lightweight and portable.
