BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a coating film transfer tool for transferring to a surface a coating film for correction, an adhesive, a decorative coating film or the like that is coated on the surface of a transfer tape base material.
2. Description of Related Art
A conventional coating film transfer tool is disclosed in Japanese Published Unexamined U.M. Application No. 13860/1995. This conventional coating film transfer tool basically has a structure as illustrated in FIG.
7
(
a
) in which a transfer head
54
of this coating film transfer tool
50
can be rotated about the axis of a pivot shaft
60
(FIG.
7
(
b
)) rotatably provided in a main body
52
(cassette). Further, the transfer head
54
is provided with tape guides
56
,
56
for controlling the movement of the transfer tape T in the lateral direction (the direction of the width of the tape T) outside the main body.
A pressing transfer part
62
formed on the tip portion of the transfer head
54
and extending lengthwise in the lateral direction slightly protrudes from the ends of the tape guides
56
,
56
. The tape T passes over the application side of the pressing transfer part, which is the side facing the receiving surface, the laterally extending separating edge of the pressing transfer part
62
, and then the return side (the upper side in FIG.
7
(
a
)) of the pressing transfer part
62
. The end edge of the pressing transfer part
62
is perpendicular to the axis of the shaft
62
, about which the head
54
is rotatable.
A tape unreeling rotary part
51
upstream of the head
54
and a tape reeling rotary part
53
, or take-up reel, downstream from the head
54
are rotatably provided in the main body
52
.
The transfer tape T, which is coated with a coating film, is reeled around the tape unreeling rotary part
51
and passes over the pressing transfer part
62
protruding outside from the tape guides
56
,
56
with its coated side facing outward. Prior to running over the return side of the pressing transfer part, the tape T is separated into the coating film transferred to a receiving surface and a remaining tape base material as the application side of the part
62
is pressed against and moved over the receiving surface, and only the tape base material is reeled around the tape reeling rotary part
53
.
FIG.
7
(
b
) is an enlarged perspective view of the main part of the coating film transfer tool
50
illustrated in FIG.
7
(
a
). The transfer tape T is omitted in FIG.
7
(
b
).
Triangular plate-shaped tape guides
56
,
56
are formed on both sides of the transfer head
54
and, as described above, the pressing transfer part
62
protrudes from the tape guides
56
,
56
.
Therefore, when the pivot shaft
60
is rotated, the tape guides
56
,
56
are also rotated about the same axis with respect to the main body
52
.
While the transfer tape not shown is moved from the transfer head
54
to the pressing transfer part
62
to transfer the coating film to the surface to be transferred and then the remaining tape base material is returned from the transfer head
54
into the main body
52
, the transfer tape T is guided by the triangular plate-shaped tape guides
56
,
56
. Thus, the position of the transfer tape T is regulated in the lateral direction.
When the coating film transfer tool
50
is used, the main body
52
is gripped by hand and the pressing transfer part
62
is moved in the direction shown by an arrow in FIG.
7
(
a
) while it is pressed on the desired position of the surface to be transferred. Then, the tape unreeling rotary part
51
and the tape reeling rotary part
53
are rotated and the transfer tape T is unreeled from the tape unreeling rotary part
51
and is moved in the direction of the receiving surface and the coating film on the surface of the transfer tape T is transferred by the pressing transfer part
62
to the receiving surface. The remaining tape base material is reeled around the tape reeling rotary part
53
.
Since the pressing transfer part
62
formed on the tip portion of the pivot shaft
60
is pivotally mounted on the main body
52
, the transfer tape T guided by the tip portion of the pressing transfer part
62
is also twisted by the pivoting of the pressing transfer part
62
.
Therefore, in the coating film transfer tool
50
, even if the main body
52
is inclined to the surface to be transferred when the coating film is transferred to the surface to be transferred, the transfer head
54
is rotated and the transfer tape T is also twisted thereby and the whole width of the transfer tape T is uniformly put into close contact with the surface to be transferred, whereby the coating film can be correctly transferred to a desired location.
FIG. 8
is a cross-sectional view of the coating film transfer tool
50
taken on line

—

in FIG.
7
. FIG.
8
(
a
) illustrates a normal position in which the transfer head
54
is not rotated and the tape is not twisted and FIG.
8
(
b
) illustrates a twisted position in which the transfer head
54
is rotated and the tape is twisted.
As illustrated in FIG.
8
(
b
), this type of coating film transfer tool
50
can be difficult to transfer the coating film if the pivot angle of the head, and therefore the twist of the tape, is excessive. If the main body
52
is inclined excessively to the surface to be transferred and the pivot shaft
60
is rotated thereby, the tape guides
56
,
56
formed on the transfer head
54
are also rotated and put into contact with the transfer tape T. This can hinder the transfer tape T from running, peel the coating film on the transfer tape T off from the tape base material, or detach the tape T from the pressing transfer part
62
.
Further, the rotated tape guides
56
,
56
may exert a strong force to the transfer tape T, whereby the tape T might be cut.
In this respect, in this type of coating film transfer tool, a strong force is applied to the bottom of the pressing transfer part
62
pressed on the surface to be transferred and hence the transfer tape T tends to be moved in the lateral direction when the user's hands are unsteady. However, in the conventional coating film transfer tool
50
, as is evident in FIG.
7
(
b
), the pressing transfer part
62
itself can not control the movement of the transfer tape T.
Since, this type of coating film transfer tool
50
has the pressing transfer part
62
on the axis of the pivot shaft
60
, when it is used, a slant angle D (see FIG.
7
(
a
)) made by the pressing transfer part
62
and the receiving surface is small. Distance P between the main body
52
and the receiving surface is also small, which makes it difficult to see the receiving surface ahead of the tool and, in particular, the end position of transfer.
Since the transfer head
54
has triangular plate-shaped guides on both sides to control the position of the transfer tape T, it is difficult to check the end position of transfer because the guides obstruct the view. Therefore, it is difficult to finish transferring the coating film correctly at a desired position.
Thus, it can be difficult to correctly erase particular letters in a printed sentence.
SUMMARY OF THE INVENTION
To solve the above-mentioned problems, the present invention provides a coating film transfer tool comprising an unreeling rotary part and a reeling rotary part that are rotatably received in a main body, a transfer tape to be separated into a coating film to be transferred to a receiving surface and a remaining tape base material via a transfer head, the tape base material being reeled around the reeling rotary part from the unreeling rotary part and the transfer head being rotated around an axis by a pivot shaft mounted in the main body. A pressing transfer part is formed on the tip portion of the transfer head which protrudes from the main body, and tape controlling members are provided only on the retu
