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 and its problems]

 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 the thin correction paint layer provided on the tape base material onto the paper surface, so compared to the former adhesive correction tape in which an adhesive paper tape itself is applied, the appearance is improved. There is a small difference between the modified part and the unmodified part in terms of touch and touch, and there is an advantage that a beautiful modification can be performed.

As a correction tool using such a transfer type correction tape, a method of automatically winding a tape base material after transfer has been widely used. This is a transfer type correction in which a feeding gear and a take-up reel having a gear that meshes with the feeding gear are mounted in a case with a transfer head at one end, and fed from a tape reel fitted to the boss of the feeding gear. The tape is folded back via the peeling edge of the transfer head, and by moving the folded back portion while pressing it against the paper surface, the correction paint layer on the tape base material is continuously transferred to the paper surface. At the same time, the feeding gear is rotated by the pulling action of the tape that moves back the peeling edge during transfer, and the tape base material after transfer is automatically wound by the winding reel that rotates in conjunction.

In this case, of course, it is necessary that the amount of correction tape fed out from the tape reel and the amount of winding by the take-up reel match, but with use, the winding diameter of the tape reel decreases and the correction tape While the reel rotation amount per unit feed length increases, the winding diameter of the take-up reel also increases, and the winding amount per unit rotation amount increases. It becomes impossible to operate when and rotate together.

Therefore, in the conventional general-purpose correction tool, the gear ratio is set so that the take-up reel rotates faster than the pay-out gear, and the core of the tape reel has an internal gear shape, and the boss portion of the pay-out gear is formed. Is provided with a claw piece that elastically meshes with the inner teeth of the core so that a rotational deviation occurs between the tape reel and the feeding gear when a load larger than a predetermined value is applied between them. . That is, according to this structure, when the tape is unwound in accordance with the transfer correction, the unwinding gear tries to rotate integrally with the tape reel, and the take-up reel also tries to rotate more rapidly. Cannot take up more tape than the take-up amount, a braking action from the take-up reel side occurs, and the take-out gear has a position in which the inner teeth of the core part and the claw pieces are displaced from each other with respect to the tape reel. The rotation delays, and the tape is automatically wound by the feeding amount while maintaining the tension between both reels.

However, in the correction tool having the above-mentioned configuration, the meshing position between the inner teeth of the core portion of the tape reel and the claw pieces of the feeding gear shifts during the transfer correction as described above, so that it is stiff. It produces a jarring intermittent sound and gives a bad feeling to the user, and the tape reel and take-up reel rotate at a fine pitch while repeating speed changes or intermittent operations, making it difficult to transfer smoothly and sticking to the paper surface. There was a problem that the surface of the correction paint layer was likely to be wavy.

Therefore, instead of meshing the inner teeth of the core portion with the claw pieces, an O-ring is interposed between the boss portion of the feeding gear and the inner circumference of the core of the tape reel, or feeding is performed by a coil spring. It has been proposed that the gear and the tape reel are elastically contacted in the axial direction so that the rotational deviation between the payout gear and the tape reel due to the payout / winding of the tape is generated steplessly. All of these are intended to enable the interlocked rotation involving the locking of both when not transferring and the shift during transfer due to the frictional force between the feeding gear and the tape reel, but the frictional force is too small. When the tape is transferred, only the tape reel rotates and the tape cannot be taken up.When the tape reel swings when it is not in use, the tape reel will rotate, causing the correction tape to slacken. If the force is too large, the tape reel will not rotate easily during transfer, and the tape will slide on the paper surface at the transfer part, causing transfer breaks in the correction paint layer. Therefore, the setting of the above friction force is extremely important. Becomes

However, in the structure using the O-ring, the elastic restoring force against the compressive deformation is used, but since the variable amount of the compressive deformation is small with a small wire diameter, it is very difficult to adjust the frictional force. Strict dimensional accuracy is required for the intervening portion, and even if there is a slight deviation in the set gap between the outer circumference of the boss of the feeding gear and the inner circumference of the core of the tape reel, there is the problem of malfunction. On the other hand, in the structure using the coil spring, the elastic repulsive force against the compression of the beam is used, but the spring force varies greatly morphologically, the frictional force often deviates from the set range, and a large axial loading force is required. There is a drawback that the correction tool case becomes bulky due to the need for space and that the assembly operation is difficult because the case is assembled in a compressed state.

[0009]

[Means for Solving the Problems]

 In consideration of the above situation, the present invention is a transfer type correction tool that automatically winds up a tape base material after transfer, has a good usability without generating annoying sound during transfer, and has a smooth transfer correction. The object is to provide a tape which has a good surface, is excellent in smoothness and stability of feeding and winding of the tape, and has a constant quality.

That is, the transfer type correction tool according to claim 1 of the present invention, as a means for achieving the above object, presses the transfer type correction tape fed from the tape reel onto the paper surface via the peeling edge of the transfer head. As a result, the correction paint layer of the tape is transferred to the paper surface, and in the transfer type correction tool in which the tape base material after transfer is wound onto the take-up reel, in the case where the transfer head is provided at one end, The take-up reel having a large-diameter feeding gear and a small-diameter gear meshing with the large-diameter feeding gear is mounted, the tape reel is loosely fitted to the boss portion of the feeding gear, and the tape reel and the feeding gear are The annular leaf springs employ a configuration characterized in that they are temporarily locked to each other by the pressing force in the axial direction.

According to a second aspect of the present invention, in the transfer type correction tool according to the first aspect, an annular receiving plate is fitted on the tip side of the boss portion of the feeding gear, and the annular receiving plate and the feeding gear are attached. A tape reel and an annular leaf spring are fitted between the gear disc portion and the gear disc portion.

Further, a third aspect of the present invention is the transfer type correction tool according to the first or second aspect, wherein the annular leaf spring has a wave washer shape.

[0013]

[Action]

 In the transfer type correction tool of the present invention, the feeding gear and the tape reel loosely fitted to the boss portion are temporarily locked to each other by the axial pressing force of the annular leaf spring, so that the axial movement of both of them can be prevented. Due to the frictional force of the opposite sliding contact surfaces, the locked state of both is maintained during non-transfer, and during transfer, the feeding gear is delayed due to the braking action from the take-up reel side that meshes with the feeding gear. It rotates in conjunction with the tape reel. Since the tape reel and the feeding gear are deviated in rotation from each other in a stepless manner due to the sliding between the sliding contact surfaces, no harsh sound is produced and smooth transferability is obtained. In addition, the annular leaf spring has a small variation in spring force, and it is easy to set the above frictional force. Therefore, the tape feeding during transfer is lightened, and even if it is shaken when not in use, the tape In addition to providing a locking force that does not cause loosening, a large loading space such as a coil spring is not required, and the size of the correction tool case can be reduced.

In the structure in which the annular receiving plate is fitted on the tip side of the boss portion of the feeding gear, and the tape reel and the annular leaf spring are fitted between the annular receiving plate and the gear disc portion of the feeding gear, Since the reel and the annular leaf spring are both held by the feeding gear, they can be assembled in the case in the form of an integral body fitted in advance to the boss portion when assembling the correction tool.

A disc spring or a wave washer spring can be used as the annular leaf spring. However, since the latter wave washer spring contacts the opposite surfaces on both sides with wavy convex curved surfaces, the sliding resistance is small, so pressing force is applied to avoid slackening of the tape when not in use. Even if is set strongly, the rotational deviation between the tape reel and the feeding gear at the time of transfer can be performed very smoothly.

In FIG. 1, reference numeral 1 denotes a case made of a hard synthetic resin molded product, which is a long box-shaped reel housing portion 2 on the rear side, which is slightly flat in the vertical direction, and a long tubular portion 3 on the front side, which has a substantially rectangular tube shape. The transfer head 4 projects from the circular opening 3a at the front end of the long tubular portion 3. Thus, the long tubular portion 3 constitutes a gripping portion 5 having a substantially regular square shape in which the front side is provided with the serrations 5a on the peripheral surface, and the rear end of the long tubular portion 3 has a rectangular front end outer shape of the reel accommodating portion 2. The shape is such that the vertical width increases toward the rear to match. Reference numeral 6 denotes a twisting portion provided on one side surface of the reel housing portion 2 for slack correction.

The reel accommodating portion 2 is composed of a main body 2a and a lid body 2b fitted to the main body 2a in a vertically split shape. As shown in FIG. 2, a long strip-shaped support piece protruding forward from the front end face thereof. 7 is integrally formed on the main body 2a side, and the transfer head 4 is integrally provided at the tip of the support piece 7. Then, as shown in FIG. 3, the support piece 7 is arranged such that its main surface is along the lateral direction, and the short locking pieces 7a, 7a projecting on both left and right sides near the front end are long. It engages with locking grooves 3b, 3b on the inner peripheral surface of the tubular portion 3 near the front end. Further, as shown in FIGS. 3 and 4, the transfer head 4 has a plate-shaped portion 4a on the extension of the support piece 7 which has a spatula-shaped peeling edge 4b, and is formed on both left and right sides of the plate-shaped portion 4a. It has guide parts 4c and 4c. These guide portions 4c, 4c are formed so that their outer side surfaces form a substantially conical peripheral side surface with the peeling edge 4b side as the top, and project to both sides in the thickness direction of the plate-shaped portion 4a. A ridge 4d extending along the edge direction is provided on the tape pull-out side (lower surface side) of the peeling edge 4b.

As shown in FIGS. 2 and 5, in the reel housing portion 2, the large-diameter feeding gear 10 is attached to the cylindrical support shafts 8 and 9 which are protruded one after another on the inner surface side of the main body 2a. A small diameter winding gear 11 meshing with this and a small diameter winding gear 11 are rotatably fitted. The feeding gear 10 has a boss portion 10b protruding to one side of the gear disc portion 10a, and a wave washer-shaped annular leaf spring 12 and a tape reel 14 of a transfer type normal tape 13 are loosely fitted to the boss portion 10b. At the same time, the annular receiving plate 15 is press-fitted to the tip of the boss portion 10a. As shown in FIGS. 6 and 7, the annular leaf spring 12 has a three-cycle wave washer shape, and is disposed between one end surface of the core 14a of the tape reel 14 and the inner side surface of the gear disk portion 10a. , Which are in a compressed state, are in contact with the opposite surfaces at three wave crests 12a, respectively, and the elastic repulsive force presses the tape reel 14 toward the annular receiving plate 15.

The core 14a of the tape reel 14 is configured to be longer than the width of the tape 13, and the tape 13 is fitted to the end face of the annular leaf spring 12 side such that one winding side face is substantially flush. There is. Further, the annular receiving plate 15 has a tape-shifting flange portion 15a which is arranged close to the other winding side surface of the tape 13, and the other side of the core 14a is formed by an annular convex portion 15b formed on the inner side surface. Is in line contact with the end face of. Both outer side surfaces of the gear disk portion 10a and the annular receiving plate 15 are in contact with annular convex portions 16a and 16b formed on both inner surfaces of the main body 2a and the cover plate 2b of the reel housing portion 2, respectively. Reference numeral 17 denotes an engaging shaft projectingly provided on the inner surface of the cover plate 2b, which is press-fitted to the tubular support shaft 8.

The boss portion of the take-up gear 11 fixes the start end of the transfer type correction tape 13 derived from the tape reel 14 as the take-up reel 18. The small-diameter tip portion 18a of the take-up reel 18 is inserted into an annular projecting edge 19 formed on the inner surface side of the cover plate 2b of the case 2 and exposed to the outside, and an arc formed on this end surface. The groove on the bottom constitutes the twisting portion 6.

As shown in FIG. 2, the transfer type correction tape 13 unwound from the tape reel 14 passes through the inside of the long tube portion 3 from one window portion 20 a provided on the front end surface of the reel housing portion 2, and the transfer head It is arranged so that it is folded back at the peeling edge 4b of No. 4 and returns to the inside of the reel housing section 2 from the other window section 20b and is wound up by the take-up reel 18. In this case, the width direction of the tape 13 on both reels 14 and 18 and the direction of the peeling edge 4b are aligned with each other, and the tape 13 is in a twist-free state. The transfer type correction tape 13 has a correction coating layer provided on a tape base material such as polyester, and a general commercially available product can be used.

Reference numeral 21 shown by phantom lines in FIGS. 4 and 5 is a cap having a through hole 21 a, which is fitted to the cap mounting portion 3 b at the end of the long tubular portion 3 to protect the transfer head 4 when not in use. Has been done.

In order to correct characters and lines with the transfer type correction tool having the above-mentioned configuration, the peeling head 4b of the transfer head 4, that is, the folded-back portion of the transfer type correction tape 13 is pressed to the start position where the correction of the paper surface is required. All you have to do is to pull the correction tool and move it while it is pressed. By this operation, the correction paint layer on the front surface side of the tape 13 is peeled off from the tape base material, and at the same time, it is transferred to the paper surface due to the adhesiveness of the surface, and the tape 13 is unwound from the tape reel 14 by the pulling action accompanying the movement. Then, the feeding gear 10 rotates in association with the rotation of the tape reel 14 due to this feeding, and the take-up reel 18 meshing with this also rotates to automatically wind the tape base material after the correction paint layer is peeled off. take. Then, although the characters and lines are hidden and erased by the correction paint layer transferred to the paper surface, the correction characters and lines can be immediately written on this paint layer.

Here, since the feeding gear 10 and the tape reel 14 are pressed against each other by the axial pressing force of the annular leaf spring 12 and temporarily locked, the tape 13 is removed by the above-mentioned transfer correction. At the time of feeding, the feeding gear 10 tries to rotate integrally with the tape reel 14, and the take-up reel 18 also tries to rotate in conjunction therewith. However, since the take-up gear 11 has a small diameter with respect to the rotation of the pay-out gear 10 and thus rotates at a higher speed, the take-up reel 18 cannot take up more than the amount of the tape 13 taken out, and therefore the take-up reel 18 side. The brake action from is generated. Therefore, the feeding gear 10 during the transfer correction slides on the tape reel 14 on the opposing surfaces via the annular leaf spring 12 and on the opposing surface with the annular receiving plate 15, and smoothly and steplessly. The rotation is delayed. Then, the tape 13 at the feeding portion from the tape reel 14 to the take-up reel 18 via the transfer head 4 is always kept in a tension state by the pulling action from the take-up reel 18 side which is about to rotate at an increased speed. Further, when not in use, the tape reel 14 is locked to the feeding gear 10 by the annular leaf spring 12, so that there is no fear that the tape 13 will start to loosen even if the correction tool is shaken by transportation or the like.

In the above embodiment, a wave washer type is used as the annular leaf spring, but a disc spring may be used instead. FIG. 8 shows an example thereof, and the disc spring 22 has a plurality of cut-and-raised pieces 22b ... Erecting inwardly and obliquely upward on the inner peripheral side of the flat ring portion 22a. And exerts a spring force due to the elasticity of the cut-and-raised pieces 22b.

Further, in the embodiment, the annular leaf spring 12 is interposed between the gear disk portion 10 a of the feeding gear 10 and the tape reel 14, but it goes without saying that it is between the annular receiving plate 15 and the tape reel 14. Even if they are arranged, they are the same, and even when the annular receiving plate 15 is loosely fitted to the boss portion 10b of the feeding gear 10 without being integrated, the same temporary locking action by the spring force can be exerted. Further, in this invention, in a structure in which the annular receiving plate 15 is omitted, an annular leaf spring is arranged between the gear disc portion of the feeding gear and one core end surface of the tape reel as in the embodiment, and the tape reel is Of the other core end surface of the tape reel is in direct sliding contact with the inner surface of the case. An annular leaf spring is arranged between the inner surface of the case and the core end surface of the tape reel, and the other core end surface of the tape reel and the gear of the feeding gear. The ring plate spring is placed between the inner surface of the case and the facing gear disk, and the core end surface of the tape reel and the gear disk of the feeding gear slide directly. It is also possible to adopt a configuration in which two annular leaf springs are in contact with each other, and two annular leaf springs are interposed at two different positions in the above-described exemplary configuration.

The present invention is not limited to the illustrated ven-shaped one, but can be applied to various transfer type correction tools having different cases and transfer head shapes.
