Description

  The present invention relates to a technical field of a transfer head of a coating film transfer tool used to transfer a correction coating film, an adhesive for adhesion, a decorative coating film, etc. coated on the surface of a transfer tape base material to a transfer surface. Belongs.

Conventionally, in a coating film transfer tool using a correction tape for correcting an error caused by a writing instrument such as a ballpoint pen, the tip of the transfer head is in close contact with the correction portion on the transfer body, By sliding the coating film transfer tool and pressing the correction tape from the back direction, the correction coating film on the correction tape can be transferred onto the transfer target body, and the correction tape at a necessary position. Therefore, the shape of the transfer head is such that the tip portion is thinner. (For example, Patent Document 1)
It has also been proposed to provide inward notches on both side edges in the width direction at the leading end of the transfer head so that the leading end of the transfer head can reliably maintain contact with the paper surface. (For example, Patent Document 2)

  However, in the transfer head of the conventional coating film transfer tool, the pressure transfer portion is designed to be linear in the tape width direction so that the correction tape can be uniformly pressed onto the transfer surface. Depending on the molding conditions of the head and the finished state of the molding die, the press transfer part may be curved. When this curved state turned into a reverse warped state, the transfer tape could not be uniformly crimped at the pressure transfer portion, and the transferred corrected coating film might float. Further, even when there is no molding problem and the pressure transfer portion is linear, the pressure transfer portion is not perpendicular to the transfer surface during the transfer operation, and the transfer head travel direction When the pressing force is large, the pressing transfer portion bends and warps back to the opposite side, and sufficient pressure is not transmitted intensively and evenly to the correction tape. As a result, it was difficult to accurately transfer the corrected coating film, and the correction coating film could not be sufficiently cut off at a necessary location.

  In addition, in the case of a transfer head in which inward notches are provided on both side edges in the width direction at the front end of the transfer head, when the notches are provided, the tape guide from the head end to the tape due to the problem of securing the strength of the molding die. It is necessary to increase the distance to the head, so that the effect of the tape meandering reduction is reduced and the tape is likely to come off. There were problems such as shape defects at the tip and insufficient strength.

  An object of the present invention is to provide a coating film transfer tool capable of obtaining an excellent transfer coating film by uniformly contacting a transfer surface of a transfer head of a transfer head during transfer.

In order to achieve the above object, it has a feeding rotation part, a winding rotation part, and a transfer head, and the transfer tape is divided into a coating film transferred to the transfer surface via the transfer head and the remaining tape base material, The tape base material is wound up from the feeding rotation unit to the winding rotation unit, a pressure transfer unit is formed at the tip of the transfer head, and tape guides are formed at both ends in the width direction of the transfer head. In the coating film transfer tool provided, the thickness of the upper surface portion of the tip portion of the tape guide has a thin portion that is thinner than the thickness of the pressure transfer portion, and satisfies the following requirements: It is comprised from the coating-film transfer tool characterized by doing.
(1) At the time of pressure transfer, the thin wall portion is elastically deformed, and the pressure transfer portion becomes a shape that is straight along the transfer surface.

Moreover, the said coating-film transfer tool is good also as a structure where the cross-sectional shape of the said thin part is trapezoid shape.

Further, in the coating film transfer tool, a cross-sectional shape of the thin-walled portion starts from both end portions, and a flat portion whose thickness is constant as it goes to the central portion and whose thickness is smaller than the central portion, and from the flat portion to the central portion It is good also as a structure which consists of an inclination part which becomes thick as it goes to.

According to the present invention, the thickness of the upper surface portion of the front end portion of the tape guide has the thin portion that is thinner than the thickness of the pressure transfer portion. Only the both ends of the pressure transfer part are elastically deformed so that the pressure transfer part is straight along the surface to be transferred, and the pressing force is reliably transmitted to the transfer tape via the pressure transfer part. A transfer coating film is obtained.

  In addition, when molding the transfer head, it is not necessary to provide notches facing inward on both side edges in the width direction at the tip of the transfer head, and it is not necessary to increase the distance between the head tip and the tape guide, making it easy to manufacture the mold. In addition, since there are no defects such as molding defects and insufficient strength, the manufacturing cost can be reduced.
