Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is used to correct characters and lines written on paper, and to transfer the correction paint layer of a transfer type correction tape to the corrected portion to conceal and erase the characters and lines. The present invention relates to a transfer type correction tool.

[0002]

[Prior art]

 In recent years, adhesive correction tapes and transfer type correction tapes have been introduced for the correction of characters and lines written on paper by various writing instrument inks, printing, type printing, word processor printing, copying, etc. Demand is increasing because quick corrections can be made without the drying time required with paint-type correction fluids and there is no risk of soiling hands or the surrounding area. In particular, the latter transfer-type correction tape transfers only a thin correction paint layer onto the paper surface, so compared to the former adhesive correction tape in which an adhesive paper tape itself is adhered, it has a better appearance and feel than the modified part. It has the advantage of being able to make beautiful corrections with a small difference from the uncorrected parts.

As a transfer type correction tool using such a transfer type correction tape, various types of structures have been proposed in the past, but from the viewpoint of transferability and operability, for example, Japanese Patent Publication No. 3-11639. , The transfer type correction tape fed from the tape reel is wound around the take-up reel via the tip of the transfer head, and the tip of the transfer head is pressed against the paper surface to move. By doing so, it is preferable to continuously transfer the repair paint layer on the tape substrate to the paper surface. As a correction tool of this kind, the holding member of the tape reel and the take-up reel are mounted in the case so as to rotate synchronously via a gear, and the pointed end of the transfer head is pressed against the paper surface. The holding member is rotated by the pulling force of the tape when it is moved, and the take-up reel is rotated in conjunction with this, and it is commercially available. As the transfer head, a transfer head made of a hard synthetic resin molding and having a flat shape with a sharp end having an edge along the tape width direction as a so-called peeling edge is used.

[0004]

[Problems to be solved by the device]

 By the way, with this type of transfer type correction tool, in order to surely conceal and erase the part that requires correction, the thin correction paint layer peels off continuously from the tape base material during transfer without tearing, and it firmly adheres to the paper surface. Need to be applied to. However, with the conventional transfer type correction tool, when the base of the document to be corrected is soft, for example, correction is performed with a stack of multiple sheets of paper, or a disc mat made of soft synthetic resin is used to make corrections. Although there is no problem, when the base is hard, the correction paint layer does not peel off uniformly over the entire width of the tape during transfer and is likely to remain partially on the tape substrate, which causes chipping or breaks in the correction coating. Then, there was a problem that proper correction could not be performed.

In view of the above situation, an object of the present invention is to transfer a correction paint layer of a transfer type correction tape fed from a tape reel onto a paper surface via a transfer head, and transfer the tape base material to a take-up reel. It is to provide a transfer type correction tool having a take-up structure that can obtain good transferability even when the base of the document to be corrected is hard, is easy to operate, and can always make appropriate corrections.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the transfer type correction tool according to the present invention is constructed such that a tape reel and a take-up reel are mounted in a case having an opening at one end side, and the tip is sharpened from the opening. A transfer head made of a hard synthetic resin molded product is attached, and the transfer type correction tape fed out from the tape reel is folded back through the cusps of the transfer head, and the folded portion is pressed against the paper surface. In a transfer type correction tool configured to roll a correction paint layer on a base material onto the paper surface and wind a tape base material onto a take-up reel, an elastic layer is formed on the surface of the pointed portion of the transfer head. It adopts a configuration that is characterized by

[0007]

[Action]

 The transfer pressure at the time of correction by this type of transfer type correction tool, that is, the pressing pressure of the coating head on the paper surface is about 150 to 200 g at a tape width of 4 mm and about 200 to 250 g at a tape width of 6 mm in a normal use state, Operationally, it tends to be slightly lower at the start of transfer. However, in the conventional transfer type correction tool, since the cusps of the transfer head made of a hard synthetic resin molding are hard, when the correction operation is performed while the substrate is hard, the edge direction of the cusps is on the substrate surface. On the other hand, even if it is slightly inclined, the correction paint layer on one side of the tape width is not transferred due to insufficient pressure and is likely to remain on the tape base material. It is considered that due to distortion or the like, a region where a sufficient transfer pressure is not applied is generated, and as a result, the correction coating film is chipped or discontinuous as described above.

However, since the transfer type correction tool of the present invention has the elastic layer on the surface of the pointed portion of the transfer head, when the base of the correction document is fixed in a hard state, the tip edge direction of the pointed tip is lower ground. Even if it is slightly inclined with respect to the surface of the paper, even if there are minute irregularities in the paper, changes in thickness, or irregularities or distortions in the base surface, the correction tape strongly adheres to the paper surface over the entire width due to the deformation of the elastic layer, As a result, a sufficient transfer pressure acts on the entire width of the tape to form a repaired coating film without chipping or breaks.

Such an elastic layer is formed by applying a solution or emulsion of an elastomer such as synthetic rubber or a soft synthetic resin having rubber elasticity by a dipping method or brush coating, or by sticking a tape of the same material. , Can be easily formed.

It is possible to form the transfer head itself with an elastic material such as a soft or semi-hard synthetic resin or rubber instead of providing the elastic layer described above. Since the whole is deformed by pressing at the time and the correction tape at the folded back part is loosened, the feeding and winding cannot be performed well, and the function as the peeling edge is deteriorated, which rather deteriorates the transferability. It is poor in practicality. On the other hand, in the transfer type correction tool of the present invention, the transfer head has sufficient rigidity, so that the above problem does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, 1 is a case, 2 is a transfer head projectingly arranged in an opening 10 on one end side of the case 1, and 3 is a feeding gear mounted in the case 1 near the opening 1a. Reference numeral 4 denotes a tape reel fitted in the boss portion 30 of the feeding gear 3, and reference numeral 5 denotes a take-up reel loaded on the side farther than the opening 1a in the case 1. All of these members 1 to 5 are provided. It consists of a hard synthetic resin molding. Then, the transfer type correction tape 6 fed from the tape reel 4 is wound around the take-up reel 5 via the transfer head 2 as shown in the figure.

The case 1 has a configuration in which a pair of vertically divided half-split bodies 1a and 1b (see FIG. 5) are fitted and assembled, and as shown in FIG. 2 and FIG. Cylindrical support shafts 11a, 11b for rotatably mounting the feeding gear 3 and the take-up reel 5 are provided on the inner wall surface, and an annular convex portion 12a and an annular rack concentric with the support shaft 11a are provided. 13, a ring-shaped convex portion 12b concentric with the support shaft 11b, and a shaft portion 14a and a circular arc wall portion 14b concentric with the shaft portion 14a projecting in the vicinity of the opening 10 to form a mounting portion for the transfer head 2. A locking groove 14c in the height direction is provided on the inner surface of the arc wall portion 14b. Reference numeral 15 is a tape guide pin on the winding side, which is provided on the inner wall surface of the half-split body 1a. Further, the half-split body 1b is provided with a fitting pin 16 that is fitted into the cylindrical support shaft 11a on the inner wall surface, and has an opening 17 at a position facing the cylindrical support shaft 11b.

As shown in FIGS. 3 and 4, the transfer head 2 has a plate-shaped head piece 21 having a tip 2 a at one end side of an arcuate base portion 20 and a tip end at the other end side. A thin strip-shaped plate-shaped pressing piece 22 is continuously connected so as to form a C-shape when viewed from the side, and a pair of triangular guide pieces 23, 23 are provided on the left and right sides near the tip of the head piece 21. It is integrally formed, and has an engaging convex shape 20a extending along the width direction on the outer surface of the base portion 20 and a protrusion 20b on the outer surface side of the boundary portion between the base portion 20 and the head piece 21. An elastic layer 24 made of rubber is formed on the front surface of the head piece 21.

In the transfer head 2, the base portion 20 is fitted between the shaft portion 14a and the arcuate wall portion 14b of the case 1 so that the engaging projection 20a engages with the engaging groove 14c. As shown in FIG. 4, the front end side of the head piece 21 having the guide pieces 23, 23 is attached to the case 1 so as to project outward from the opening 10. In this mounted state, the transfer type correction tape 6 fed out from the tape reel 4 has its U-shaped tip in a state of being elastically contacted from the back side by the pressing piece 22 of the transfer head 2 as shown in FIGS. 1 and 3. Through the opening 10 of the case 1 and then folded back between the guide pieces 23 of the transfer head 2 in contact with the elastic layer 24 of the cusp 2a and into the case 1 through the opening 10. It returns and is taken up by the take-up reel 5.

As shown in phantom lines in FIG. 2 and FIG. 5, the feeding gear 3 has teeth 3a on the disk-shaped peripheral edge, and the teeth 5a forming the gear on the bottom side peripheral edge of the take-up reel 5 as well. Are engraved, and both teeth 3 and 5 are interlocked with each other by engaging both teeth 3a and 5a with the bosses 30 and 50 mounted on the support shafts 11a and 11b of the case 1. It is set to rotate. The ring-shaped protrusions 12a and 12b on the case 1 side have a function of reducing the sliding contact resistance in the above-described interlocked rotation by bringing the bottom surfaces of the feeding gear 3 and the take-up reel 5 into line contact with the case 1. Fulfill Thus, the feeding gear 3 has an arc-shaped return prevention piece 3b, and as shown in FIG. 6, a pawl 31 provided at the tip thereof meshes with the annular rack 13 on the case 1 side to form a ratchet mechanism. However, this prevents rotation in the returning direction (counterclockwise direction in FIGS. 1 and 2).

Further, as shown in FIG. 1 and FIG. 5, the boss portion 30 of the feeding gear 3 is a plurality of (four in the figure) engagement members having outwardly facing claws 32 at the periphery of the cylindrical portion 30a. A stop projection piece 30b and a plurality of (four in the figure) arcuate projection pieces 30c are annularly projected. On the other hand, a tooth profile 40 is formed at the upper edge of the central hole 4a of the tape reel 4, and when the tape reel 4 is fitted into the boss portion 30 of the feeding gear 2, the tooth profile 40 has a boss portion 30. The claws 32 of the respective locking projections 30b are set so as to mesh with each other. Therefore, when the tape reel 4 is fitted in the feeding gear 3, the engagement between the tooth profile 40 and the claw 32 is within a range in which the load in the relative rotational direction with the feeding gear 3 is a certain value or less. However, when the load exceeds a certain value, the engagement is disengaged due to the elastic deformation of the locking projection 30b and the relative movement with respect to the delivery gear 2. Rotate . Reference numeral 7 shown in FIG. 5 is a ring-shaped slippery sheet interposed between the feeding gear 3 and the tape reel 4.

In order to correct characters, lines, etc. with the transfer type correction tool having the above-described structure, as shown in FIG. 3, the point 2a of the transfer head 2, that is, the transfer type correction, is moved to the starting position where the writing 8 needs to be corrected. It suffices to press the folded-back portion of the tape 6 and move the correction tool to the right as indicated by the arrow in the drawing while keeping the pressed state. By this operation, the correction coating layer 6a on the front surface side of the tape 6 is peeled off from the tape base material 6b, and at the same time, it is transferred to the writing surface 8 by the adhesiveness of the surface, and the tape 6 is removed from the tape reel 4 by the movement. Is paid out. However, since the pay-out carrier 2 rotates with this pay-out, and the take-up reel 5 rotates in conjunction with this, the tape base material 6b after the correction paint layer 6a is peeled off is taken up by the take-up reel 5. To be Then, although the characters and lines are hidden and erased by the correction paint layer 6a transferred to the document 8, the correction characters and lines can be immediately written on the paint layer 6a.

Here, when the surface of the document 8 is to be corrected in a hard state, the edge 2a of the tip 2a of the transfer head 2 to be pressed is slightly tilted with respect to the surface of the substrate, and fine irregularities and thickness of the document 8 Even if there is a change, unevenness or distortion of the base surface, the correction tape 6 strongly adheres to the writing over the entire width due to the deformation of the elastic layer 24. Therefore, a sufficient transfer pressure is constantly applied to the entire tape width, and the correction paint layer 6a is completely peeled off without remaining on the tape base material 6b and transferred to the document 8 to form a strip having a constant width without chipping or discontinuity. A beautiful modified coating film is formed on.

The elastic layer 24 provided on the transfer head 2 has only to cover at least the pointed portion 2a, and may be set to have an appropriate width according to operability at the time of forming the elastic layer 24. Further, the thickness is preferably about 0.1 to 1 mm, and if it is too thin, it cannot exert a sufficient function, and conversely, if it is too thick, the releasability of the correction coating layer 6a as a peeling edge deteriorates. .

By the way, as the remaining amount of unused tape decreases and the winding diameter of the tape reel 4 decreases as the tape continues to be used, the winding diameter of the take-up reel 5 increases. The amount of rotation increases, and conversely, the amount of rotation of the winding reel 5 required for winding decreases. However, in the configuration of this embodiment, the difference in the amount of rotation described above forces the feeding gear 3 and the tape reel 4 to rotate. Compensated by relative rotation.

Regarding the detailed configuration such as the shape and structure of each component in the transfer type correction tool of the present invention, various design changes can be made other than those exemplified in the above embodiment. For example, in order to cause the relative rotation between the feeding gear 3 and the tape reel 4 above a certain load, in addition to the means by the engagement of the tooth profile 40 and the claw 32 as in the embodiment, the feeding gear 3 and the tape. A means for imparting a certain sliding contact resistance to relative rotation may be adopted by pressing the reel 4 with a spring or by interposing a rubber member such as an O-ring between the both 3, 4. . Further, the detent means for the feeding gear 3 is not limited to the ratchet mechanism as in the embodiment, but a sliding contact resistance is given between the feeding gear 3 and the case 1 by pressing with the spring or by interposing a rubber member. Other means can be adopted as appropriate.

[Effect of device]

 According to this invention, the transfer type correction tape fed out from the tape reel is folded back through the tip of the transfer head, and the folded back portion is pressed against the paper surface so that the correction paint layer on the tape base material is applied to the paper surface. As a transfer type correction tool that transfers the tape material and winds the tape base material onto the take-up reel, it shows excellent transferability without any problems even when the base material of the document to be corrected is hard, and it can be used for operating conditions, paper surface and base surface. It is possible to obtain a correction film in the form of a strip having a constant width that is not affected by the state and is free from chipping or discontinuity. Therefore, it is possible to provide a film that can always be appropriately corrected. In addition, in order to impart the above-mentioned excellent transferability, this correction tool only needs to form an elastic layer on the surface of the pointed portion of the transfer head, and the other components are the same as the conventional type Since it may be similar to a tool, it has an advantage that it can be manufactured at low cost by using existing members and manufacturing equipment.
