Description

  The present invention relates to a so-called lateral pulling type and relatively small transfer tool that uses a surface orthogonal to the axes of the sending shaft and the winding shaft with respect to the transfer object, and the transfer tape is used as a transfer portion. It is related with the structure which cancels the skew conveyance sent out biased to the width direction one side.

  A transfer tool for transferring a transfer medium to a transfer medium such as paper has as its main component a transfer shaft portion in which a transfer tape having a transfer medium coated on a base material is wound in a housing, and transfer of the transfer tape. A take-up shaft portion that winds the substrate after the medium is transferred to the transfer target, and a transfer portion that transfers the transfer medium of the transfer tape to the transfer target. Hereinafter, the transfer tape on the delivery side and the base material on the take-up side will be collectively referred to as “base material” unless the transfer tape and the transfer medium are specifically described.

  With the transfer tool, the transfer unit exposed from the housing is pressed against the transfer target body while moving the whole on the transfer target member, so that the relative movement between the substrate and the transfer target member is caused by the output of the transfer shaft part. It becomes the driving force (and the winding driving force of the winding shaft portion), the base material is pulled out from the sending shaft portion (the base material is taken up by the winding shaft portion), and at the transfer portion when this base material is transported The transfer medium on the substrate is transferred to the transfer target.

  In order to meet the diversification of usability, the transfer tool has an opposing surface orthogonal to the axis of the delivery shaft portion and the winding shaft portion in the housing, obliquely with respect to the transferred material, that is, the opposing surface is used as the transferred material. A type that is laid face down to be parallel to the transport surface of the substrate in the transfer section (hereinafter referred to as a horizontal pulling type) and orthogonal, that is, the opposite surface with respect to the transfer target There are types (hereinafter referred to as “vertical drawing type”) that are used so as to be perpendicular to the conveyance surface of the substrate in the transfer portion.

  The vertical pulling type transfer tool is used by holding (grabbing) the outer sides of the opposing surfaces in the entire casing. On the other hand, the horizontal pulling type transfer tool is formed so as to lie on the opposite surface of the entire housing with respect to the transfer target, and to be continuously orthogonal to the edges of one and the other opposite surfaces of the housing. Grab and use the part that will be the thickness of the housing.

  For example, in each of the horizontal type transfer tools targeted by the present application disclosed in Patent Documents 1 to 4, the conveyance surface of the base material in the transfer portion is orthogonal to the axial direction of the delivery shaft portion and the winding shaft portion. doing. That is, the surface of the base material is parallel to the shaft peripheral surface at the delivery shaft portion and the winding shaft portion, but the surface is orthogonal to the transfer portion. Therefore, the surface of the base material is twisted by 90 ° in each conveyance path from the delivery shaft portion to the transfer portion and from the transfer portion to the take-up shaft portion.

  As described above, the horizontal transfer type transfer tool needs to twist the substrate by 90 ° on each of the sending side and the winding side of the conveyance path. At this time, a difference in tension occurs at both ends in the width direction of the substrate. . In other words, the substrate is subjected to a higher tension than the inner side (near side) on the outer side (far side) with respect to the center in the width direction of the conveyance surface on the trajectory twisted at both ends in the width direction. Due to the tension difference, the skew feeding toward the higher tension side occurs.

  If the substrate is transported obliquely at the transfer unit, the transfer medium may not be accurately transferred to the intended location on the transfer target, and guide walls are provided at both ends of the transfer surface of the transfer unit. If the guide wall is rubbed, the width direction end of the substrate (transfer medium in the delivery path) is damaged, and if the guide wall is not provided, the substrate protrudes from the transfer surface of the transfer portion and derails. There is a case.

  In Patent Document 1, a guide pin provided between the transfer portion and the delivery shaft portion is provided between the transfer portion and the take-up shaft portion outside the center line (in the width direction) of the transfer surface of the transfer portion. There has been proposed a configuration in which the guide pins are arranged to be shifted inward from the center line.

  In Patent Documents 2 to 4, between the transfer portion and the winding shaft portion, the conveyance direction of the base material that has passed through the transfer portion and is conveyed to the vicinity of the feeding shaft portion is substantially reversed and guided to the winding shaft portion. In addition, a configuration has been proposed in which a winding-side deflection support shaft that adjusts a tension difference in the width direction of the substrate, which will be described later, is twisted while twisting the surface of the substrate with respect to the conveyance surface of the transfer unit.

  Further, in Patent Document 4, in the transfer section having the structure of Patent Documents 2 to 3, a parallel support end for adjusting the slack of the base material and the tension difference in the width direction is provided on the transport surface on the side of feeding the base material. Has been proposed.

  The above-mentioned skew feeding of the horizontal transfer type transfer tool is unlikely to occur with a relatively large transfer tool. This is because skew feeding is caused by the distance from the transfer shaft to the transfer portion, and from the transfer portion to the take-up shaft, and these distances can be secured long in a relatively large transfer tool. This is because the tension difference is absorbed (relaxation adjustment between long distances) when the distance is long.

  In Patent Document 1, since there is no problem with the skew feeding due to the tension difference in the substrate width direction, the transfer tool is relatively small, that is, the distance from the transfer shaft portion to the transfer portion, and from the transfer portion to the winding shaft portion. If it is short, it may become apparent.

  Further, in Patent Documents 2 to 4, apart from the size of the transfer tool, the winding side deflection support shaft is provided with an angle (slanted side portion) so that the conveyance track lengths at both ends in the width direction of the substrate are equal. However, since the take-up shaft deflection support shafts of Patent Documents 2 to 4 are provided in the vicinity of the take-up shaft and are provided with the oblique sides, the base material is guided to the oblique sides (the lower side). As a result, the base material gathers at the end of the downward slope (the lower side) at the hypotenuse part of the take-up shaft deflection support shaft, and the base material may be bent or twisted.

  Further, since the parallel support ends of Patent Document 4 have the same height at both ends in the width direction, there is a possibility that the tension difference cannot be eliminated only by contact. Furthermore, by providing the parallel support end, the distance from the guide pin existing in the delivery shaft portion is shortened, and there is a possibility that the tension difference is less easily absorbed.

  In short, the configurations of Patent Documents 1 to 4 cannot absorb the tension difference in the width direction of the base material when the horizontal transfer type transfer tool is downsized, and the above-described transfer portion can feed the base material in a skewed manner. There is still a high possibility that the width direction end portion of the base material (transfer medium in the delivery path) is damaged by rubbing against the guide wall or that the base material protrudes from the transfer surface of the transfer portion and derails.

  In Patent Documents 1 to 4, the problem to be solved cannot be solved by the tension difference in the width direction caused by twisting the substrate that is inherent in the relatively small transfer tool of the horizontal pulling type by 90 °, This is a point where the base material is conveyed obliquely in the transfer portion.

  In the present invention, a transfer shaft portion in which a transfer tape having a transfer medium coated on a base material is wound in a casing, a winding shaft portion that winds up the base material of the transfer tape, and the transfer medium is transferred to a transfer target. A transfer section, having a path for twisting and transporting the transfer tape so as to be orthogonal to the axes of the delivery shaft section and the winding shaft section, and on the transport path of the base material of the delivery shaft section and the winding shaft section Each of the transfer tools is provided with a guide pin in the vicinity thereof, and a distance from the guide pin on the delivery shaft side to the guide pin on the take-up shaft portion side through the tip of the transfer portion is 70 to 120 mm. In addition, at least one of the feeding side and the winding side of the transport path of the base material is orthogonal to the transport surface of the base material in the transfer section, and one end in the width direction of the transport path of the transfer section descends from the other end. The main feature is that it has a deflecting wall inclined in a gradient.

  The term “small” in the present invention means a transfer tool in which the distance from the guide pin on the delivery shaft portion side to the guide pin on the take-up shaft portion side via the tip of the transfer portion is in the range of 70 to 120 mm. This numerical range is based on the following findings that the inventors of the present application have made various studies.

  The transfer tool having a distance from the guide pin on the delivery shaft side to the guide pin on the take-up shaft part side through the tip of the transfer part is less than 70 mm has a very short transport path in the transfer tool, that is, the transfer side and the take-up side. If the length is halved on one side, the conveyance path on one side is shorter than 35 mm, so that the space for twisting the substrate is insufficient in the horizontal drawing type, and no longer forms a body as a horizontal drawing type transfer tool. .

  On the other hand, a transfer tool in which the distance from the guide pin on the feed shaft side to the guide pin on the take-up shaft portion side through the tip of the transfer portion is longer than 120 mm has a long transport path in the transfer tool, that is, on the feed side and the winding side. Since the conveyance path on one side is longer than 60 mm when it is halved on the take side, for example, the tension difference in the width direction of the substrate is eliminated with the configuration shown in Patent Documents 1 to 4 (tension due to the conveyance path length) There is a possibility that the difference can be relaxed and absorbed.

  That is, for example, in the configurations shown in Patent Documents 1 to 4, the distance from the guide pin on the delivery shaft side to the guide pin on the take-up shaft portion side through the tip of the transfer portion is in the range of 70 to 120 mm. In the horizontal pulling type transfer tool, the tension difference in the width direction of the substrate cannot be eliminated, and there is a possibility that the transfer is performed obliquely in the transfer portion.

  Therefore, in the transfer tool of the present invention, first, by providing a guide pin on which the base material is hung on the delivery shaft portion side and the take-up shaft portion side, tension is applied in the length direction of the base material in the entire conveyance path. It was. When tension is applied by the guide pin, the base material twisted by 90 ° comes into contact with the upper end of the deflection wall while being pressed.

  The substrate just before contacting the upper end of the deflection wall is not yet completely twisted at 90 °, one end in the width direction of the substrate is higher than the other end, and the surface of the substrate is the transfer portion. If the transport surface is a reference horizontal plane, it is a slope with respect to this horizontal plane. When the base material in this state comes into contact with the upper end of the deflection wall, the end in the width direction on the side close to the conveyance surface in the transfer portion (the other end lower than the one end in the width direction of the base material = the tension is low) It contacts the high side of the hypotenuse of the deflection wall.

  Since the base material comes into contact with the upper end of the deflecting wall, the base material is given a tension corresponding to the height of the deflecting wall to the other end in the width direction of the base material with low tension. The tension difference at both ends in the width direction is adjusted toward the front end of the portion, and therefore, the substrate is suppressed from being conveyed obliquely toward the one end where the tension is high in the transfer portion.

FIG. 1 is an exploded perspective view showing the overall structure of the transfer tool of the present invention. 2A and 2B show the periphery of the transfer portion for explaining the deflection wall of the transfer tool of the present invention, wherein FIG. 2A is a perspective view, FIG. 2B is a plan view, and FIG. 2C is a side view.

  The present invention relates to the point that the substrate is conveyed obliquely due to the tension difference in the width direction of the substrate by twisting the substrate by 90 ° in a relatively small transfer tool of the horizontal drawing type. A deflection in which at least one of the feeding side and the winding side of the conveyance path is orthogonal to the substrate conveyance surface in the transfer unit, and one end in the width direction of the conveyance path of the transfer unit is inclined downward from the other end. It was solved by having a configuration with walls.

  The present invention also provides guide walls at both ends in the width direction of the transfer path of the transfer section, and at least the side of the guide wall where the guide pins are located when viewed from the center in the width direction of the transfer section. If a curved or chamfered contact portion is formed at the end of the guide pin in the direction of the guide pin, damage due to contact of one end in the width direction of the substrate with the rear end of the guide wall in the transfer portion front end direction is prevented. it can.

  Further, the present invention provides the deflection wall with respect to each of the distance from the guide pin on the delivery shaft side to the tip of the transfer unit, and the distance from the guide pin on the winding shaft side to the tip of the transfer unit. If it is provided in the conveyance path at a position from the guide pin to the transfer portion side of 70 to 85%, the above-described effect is more sure.

  Here, the deflection wall is on the transfer unit side with respect to the distance from the guide pin to the transfer shaft side guide pin to the transfer unit tip, and from the take-up shaft side guide pin to the transfer unit tip. When it is provided at a position closer to 70% (closer to the guide pin) in the direction toward the upper side, the (up) slope of the transport path with the upper end of the deflection wall viewed from the guide pin as the apex becomes a steep angle.

  When the slope of the conveyance path with the upper end of the deflection wall at the apex becomes a steep angle, the base material during guide pin conveyance approaches the upper end direction of the deflection wall in the axial direction of the guide pin. As a result, the guide pin For example, the base material may come into contact with the wall surface of the case to damage the base material or cause a conveyance failure.

  On the other hand, the deflection wall is moved from the guide pin to the transfer portion with respect to the distance from the guide pin on the delivery shaft side to the tip of the transfer portion, and from the guide pin on the take-up shaft portion side to the tip of the transfer portion. If it is provided at a position farther than 85% in the heading direction (closer to the tip of the transfer unit), the linear conveyance distance after twisting the substrate between the transfer unit and the deflection wall cannot be secured, and the substrate may be loosened. . Therefore, a deflection wall is provided at a position within the above numerical range.

  Hereinafter, specific embodiments of the present invention will be described with reference to FIGS. 1 and 2. 1 and 2 show only the essential parts necessary for explaining the features of the present invention. Reference numeral 1 denotes a transfer tool of the present invention. A transfer tool 1 according to the present invention includes a housing 2 in which a base material (= transfer tape) coated with a transfer medium is wound, a winding shaft 3 that winds up the base material of the transfer tape. And a transfer unit 5 for transferring a transfer medium of the transfer tape to the transfer target.

  In the following description, unless it is described as a transfer medium or a transfer tape, it is the base material (the transfer medium is applied to the base material on the sending side) unless it is conveyed on the path on the sending side and the winding side. Since only the base material is transported on the winding side), it is generally described as “base material”.

  The transfer tool 1 in this example forms a refill member 11 that is integrally arranged on the substrate 11A so that the delivery shaft portion 3, the winding shaft portion 4 and the transfer portion 5 can be operated. 3 shows a configuration in which the transfer medium is taken out from the housing 2 and refilled when the transfer medium is used.

  Furthermore, the transfer tool 1 in this example is of a horizontal pulling type in which the opposite surfaces of the housing 2 that are orthogonal to the axes of the delivery shaft portion 3 and the winding shaft portion 4 are laid on the transfer target. In addition, a configuration is shown in which the housing 2 is divided into a lid portion 2A and a fixed portion 2B, opened, and the refilling member 11 is refilled.

  The refill member 11 is provided with drive transmission gears (not shown and reference numerals) on the delivery shaft portion 3 and the winding shaft portion 4, respectively. An adjustment gear P that adjusts the amount of rotation between these drive transmission gears is disposed in the fixed portion 2B. Hereinafter, the description of the configuration of the transfer tool 1 other than the features of the present invention will be omitted. The transfer tool 1 is not limited to the configuration shown in this example except for the features of the present invention.

  In the refilling member 11 shown in FIG. 1, the “winding side” transport path is in front of the paper surface, and the “sending side” transport path is the back surface side (back of the paper surface) of the winding side transport path. ing. 2 (a) and 2 (b) show the conveyance path on the lower side of the refill member 11 shown in FIG. 1, that is, the winding side, and FIG. 2 (c) shows the left side direction of the refill member 11 shown in FIG. (The upper side is the winding side, and the lower side is the sending side).

  The transfer tool 1 according to the present invention includes one of a pair of substrates 11a and 11b facing each other on a surface orthogonal to the axis of the delivery shaft portion 3 and the winding shaft portion 4 in the refill member 11, in this example, for example, A sending-side guide pin 3A and a winding-side guide pin 4A are provided on a substrate 11b located on the back side of the paper surface of FIG.

  Both the guide pins 3A and 4A have a length that reaches the substrate 11a from the substrate 11b and have a constant diameter. The guide pins 3A, 4A include the center of the shaft including the center line in the width direction of the transport surface of the substrate in the transfer unit 5, and the direction away from the winding shaft 3 and the winding shaft 4 from the center line ( In FIG. 1, the guide pin 3A is disposed at a position spaced apart from the guide pin 4A.

  By doing so, the base material on the sending side and the winding side do not interfere with each other, and the base material can be appropriately tensioned in the length direction of the base material without slackening in the transport path.

  Further, in this example, the transfer tool 1 of the present invention is a return end of the transfer path on the sending side and the winding side of the transfer unit 5 and a transfer medium on the transfer target as shown in FIG. Deflection walls 5A (feeding side) and 5B (winding side) are provided on the feeding side and the winding side of the base material conveying surface of the tongue piece 5a for transferring.

  The deflection walls 5A and 5B are orthogonal to the conveyance direction of the substrate, and one end in the width direction of the substrate on the conveyance surface of the transfer unit is inclined downward from the other end. The deflection wall 5A on the delivery side is formed such that the higher portion 5Aa, which is the higher part of the upper end of the deflection wall 5A, is in contact with the (lower) side closer to the conveying surface of the tongue piece 5a in the twisted base material. The lower portion 5Ab, which is the lower part of the upper end of the deflection wall 5A, is formed on the twisted base material on the side far (high) from the conveying surface of the tongue piece 5a.

  On the other hand, the winding-side deflection wall 5B is formed with a high-order part 5Ba and a low-order part 5Bb at the upper end in line symmetry with the tongue piece 5a as the center. That is, in the conveying surface width direction of the tongue piece 5a, the side where the high-order part 5Aa of the sending-side deflection wall 5A is formed is also the high-order part 5Ba in the winding-side deflecting wall 5B, and the sending-side deflecting wall 5A. The side where the lower portion 5Ab is formed is also the lower portion 5Bb in the deflection wall 5B on the winding side.

  In this example, the deflection walls 5A and 5B are provided on the tongue piece portion 5a as described above, but on the delivery side, the conveyance path from the guide pin 3A to the tip of the transfer portion 5, and on the winding side, the guide from the tip of the transfer portion 5 is provided. If it is provided in the conveyance path to the pin 4A, it is not necessarily provided in the tongue piece 5a. Therefore, the present invention can be applied not only to the transfer tool 1 having the tongue piece 5a as the tip of the transfer part 5, but also to the transfer tool 1 having the roller as the tip of the transfer part 5. .

  In addition, the deflection walls 5A and 5B are more effective when provided so as to satisfy the following conditions. First, in the transfer tool 1 of the present invention, the distance from the guide pin 3A on the delivery shaft portion 3 side to the guide pin 4A on the take-up shaft portion 4 side via the tip of the transfer portion 5 (hereinafter, this distance is referred to as “conveyance path”). It is assumed that the distance is 70 to 120 mm).

  The reason for this is that if the transport path distance is shorter than 70 mm, the space for twisting the base material is substantially insufficient, so that it is impossible to configure as a horizontal drawing type transfer tool, and if the transport path distance is longer than 120 mm. This is based on the fact that the tension difference at both ends in the width direction of the substrate is absorbed by the distance.

  On the basis of the above assumption, the deflection walls 5A and 5B have a guide pin 3A for each of the distance from the guide pin 3A to the tip of the transfer unit 5 and the distance from the guide pin 4A to the tip of the transfer unit 5. , 4A to 70% to 85%.

  For example, in this example, when the distance A from the guide pin 3A to the tip of the transfer unit 5 is 50 mm, the distance B from the tip of the transfer unit 5 to the guide pin 4A is 45 mm, and the transport path distance (A + B) is 95 mm, the deflection wall 5A is moved to the transfer unit 5 side by 80% with respect to 50 mm of the distance A from the guide pin 3A, and the deflection wall 5B is moved to the transfer unit 5 side by 76% with respect to 45 mm of the distance B. The guide pins are provided at positions 34 mm from the guide pins 4A.

  By doing so, the base material is appropriately brought into contact with the deflection walls 5A and 5B by the guide pins 3A and 4A, and the difference in tension of the base material by the deflection walls 5A and 5B is surely performed. The skew feeding of the material is prevented.

  Furthermore, the transfer part 5 is provided with guide walls 5b at both ends in the width direction of the tongue piece part 5a so that the base material does not derail from the tongue piece part 5a. In this example, the guide wall 5b is the side where the guide pins 3A and 4A are located when viewed from the center in the width direction of the transfer unit 5 on the sending side and the winding side, for example, and the guide pins 3A and 4A on the conveyance path of the transfer unit 5 A contact portion 5C having a curved surface is formed at the end in the installation direction. The contact portion 5C may have a chamfered shape instead of the curved shape.

  The technical significance of providing the contact portion 5C will be described. The center in the width direction of the substrate in the transfer unit 5 is shifted to the side where the guide pins 3A and 4A are located when viewed from the center in the width direction of the transport surface of the transfer unit 5. This is a reason different from the skew feeding that is the subject of the present invention, that is, including the center line in the width direction of the transfer part 5 and in a direction away from the winding shaft part 3 and the winding shaft part 4 from the center line. This is because the guide pins 3A and 4A are provided.

  Accordingly, the center in the width direction of the base material is shifted to the guide pins 3A and 4A when viewed from the center in the width direction of the transfer portion 5 even if the base material is not conveyed obliquely. There is a possibility that the side where the pins 3A and 4A are located and one end in the width direction of the base material come into contact with each other. When the guide wall 5b and the base material come into contact with each other, the base material (and the transfer medium) may be damaged or a conveyance trouble may occur.

  Therefore, by forming the contact portion 5C on the guide wall 5b as in this example, even if the base material contacts the guide wall 5b, damage to the end portion in the width direction of the base material and conveyance trouble can be prevented. .

  Further, in the transfer unit 5 of this example, a sloped part 5D inclined at a downward slope toward the center toward the center in the width direction of the conveyance surface at a connection portion of the guide wall 5b with the conveyance surface of the tongue piece 5a. Is formed.

  In the transfer tool 1 of this example, even when the tension difference in the width direction of the base material is already adjusted by the deflection wall 5A and the skew feeding is suppressed, for example, when transferring the transfer medium in a meandering shape or a curved shape, The base material may come into contact with the guide wall 5b on the surface of the tongue piece 5a.

  Assuming such a use situation where the transfer medium is transferred in a meandering shape or a curved shape, if the slope portion 5D is provided, the base material comes into contact with the guide wall 5b. 5a can be returned to the center in the width direction.

  In the transfer tool 1 having the above-described configuration, the skew feeding in the transfer portion 5 of the base material inherent in the relatively small horizontal pulling type is improved. That is, the base material is fed out from the feed shaft portion 3, moderately tensioned by the guide pins 3 </ b> A, and then twisted by 90 ° with respect to the winding surface and fed toward the transfer portion 5.

  In this example, the base material reaches the rear end of the guide wall 5b before the base material reaches the deflection wall 5A. At this time, the base material is still slightly twisted and may contact the rear end portion of the delivery-side guide wall 5b, but the contact portion 5C is formed on the delivery-side guide wall 5b. The substrate is conveyed without damaging the width end of the substrate.

  The base material fed in the direction of the transfer portion 5 in a state where tension is applied contacts the upper end portion of the deflection wall 5A. At this time, in the twisted base material, the side closer to (lower than) the conveying surface of the tongue piece 5a, that is, the end side with low tension in the width direction of the base material is in contact with the high-order part 5Aa at the upper end of the deflection wall 5A. Will do.

  An end portion having a low tension in the width direction of the base material is brought into contact with the high tension portion 5Aa of the deflecting wall 5A by contacting the base portion to which the tension is applied by the guide pin 3A in the width direction of the base material. The same tension as the high end side is applied to the side. Thereafter, the transfer medium is transferred to the transfer object at the tip of the tongue piece 5 a of the transfer unit 5.

  At the tip of the tongue piece 5a, even if the substrate is transferred in a meandering or skewed manner and the substrate is transported from the center in the width direction of the tongue piece 5a to any one of the ends, the guide Since the inclined surface portion 5D is formed at the connection portion between the wall 5b and the conveying surface of the tongue piece portion 5a, it is quickly returned to the center in the width direction of the tongue piece portion 5a.

  In practice, since the base material is continuous, the difference in tension in the width direction of the base material is eliminated simultaneously by the deflection walls 5A and 5B over the entire conveyance path. In the description, the description is given in the order of the path from the sending side to the winding side.

  That is, the tension difference is further adjusted by the deflection wall 5B of the base material conveyed to the winding side beyond the front end portion of the transfer portion 5. When viewed from the winding side, the tension is applied by the guide pin 4A on the winding side contrary to the conveying direction of the base material, and further, the twisting adjustment by the deflection wall 5B is performed, so that the deflection wall on the sending side is obtained. Adjustment (correction) with 5A and the guide pin 3A is more reliable.

  Thus, by providing the deflecting wall 5B on the winding side as well, it is relatively small, that is, the transport path distance is short, but without forcibly bending the path in the entire transport path, By adjusting the tension difference in the width direction of the base material, skew feeding can be more effectively prevented.

  Further, by providing the deflection walls 5A and 5B, the height of the deflection wall 5A can be reduced as compared with the case of only the deflection wall 5A. That is, by adjusting the tension difference in the width direction of the base material with the deflecting walls 5A and 5B having a lower height than the case of only the deflecting wall 5A, an excessive tension is not applied to the base material. It is possible to prevent stretching of the material (due to slack) and damage to the transfer medium (cracking in the correction type).
