ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the construction of a coating film transfer tool for use in transferring a transfer layer provided on one side of a tape in a strippable state to a coating film receiving surface.
More particularly the present invention relates to the construction of a coating film transfer tool wherein a main body is formed small so that a superior portability is provided and wherein replacement work for a used-up coating film transfer tape is facilitated with as few operations as possible being involved. In addition, the invention relates to the construction of a coating film transfer tool which can contribute to conservation of resources and reduction in the amount of wastes by reducing the number of constituent members which are disposed in association with the replacement of refills.
2. Description of the Related Art
Conventionally, a plurality of coating film transfer tools have been devised for use in transferring repairing paint or an adhesive layer onto the surface of a piece of paper or the like, and as one of those coating film transfer tools a product is marketed in which a main body is formed small and thin.
A product, for instance, illustrated in
FIG. 27
can be taken as an example for description. The product represents the construction of a coating film transfer tool disclosed in Japanese Unexamined Patent Publication (Kokai) No. 2001-48414. This coating film transfer tool comprises a supply reel and a take-up reel which are provided in the interior of a main body of the tool in such a manner as to operate in an interlocked fashion, and a disposable type coating film transfer tape is installed in the tool for use. Normally, coating film transfer tools of this disposable type have been dominant in the market place. This is because the coating film transfer tools were originally devised as a portable product, and therefore since they are used less frequently when compared with normal products developed for office use, the disposable type coating film transfer tools can be used for a long time without replacing coating film transfer tapes. However, small coating film transfer tools like this have been so popular that they are used not only as a portable tool but also as a normal office tool since they not only provides superior convenience but also are easy to hold and require no specific place to be accommodated. However, since the amount of coating film transfer tape provided in advance in the tool is limited as a result of miniaturization of the main body, when the tool is used frequently the consumption of the coating film transfer tape increases markedly, and therefore the coating film transfer tape is often used up in the middle of use. Namely, the length of coating film transfer tape provided in the coating film transfer tool for the normal use is in the order of 10 m while the length of coating film transfer tape in the coating film transfer tool for the portable use is in the order of 5 m, and therefore when used equally frequently the coating film transfer tool for the portable use runs out of coating film transfer tape substantially two times faster than the tool for the normal use, this requiring the use to buy products of the former type quite frequently. Due to this, while with the disposable type products, the internal construction of the coating film transfer tool can be made simple and therefore they can be provided at inexpensive production costs, there are produced lots of wastes, causing problems from the viewpoints of conservation of resources and reduction in the amount of wastes to be discharged.
To cope with the problems, in recent years mechanisms have been developed for recycling fully consumed or used up coating film transfer tapes that are removed from the tools to make them reusable, and in reality there have been marketed some products having such a mechanism. Then, it can be considered to adopt the same mechanism in the small coating film transfer tools to attempt at conserving resources and reducing the amount of wastes to be discharged, but with the currently known tape replacing mechanisms there exist the following problems.
Since tape replaceable coating film transfer tools are intended to conserve resources and reduce the amount of wastes to be discharged, it is ideal to replace only the used up coating film transfer tape with a new coating film transfer tape with no other constituent component which are accessory thereto being replaced together with the tape. However, since it is difficult for the user to replace coating film transfer tapes only with ease, in reality some other constituent members are also replaced together with tapes to some extent. When looking carefully at currently marketed products, it is found that in reality quite a number of constituent members are replaced together with coating film transfer tapes when the tapes are replaced.
For example,
FIG. 28
shows a refill coating film transfer tape
800
which is disclosed in Japanese unexamined Patent Publication (Kokai) No. 6-286927. To explain specifically with reference to the tape, there have been marketed a number of conventional products adopting a cartridge type coating film transfer tape with a view to facilitating the replacement work of coating film transfer tapes. In the case of such a product, normally replaced are a coating film transfer tape
805
, a core
801
of the coating film transfer tape, a take-up reel
802
, a holder
803
, a transfer head
804
and the like. Here, to observe the operation of the coating film transfer tape, the tape is first supplied, then the coating film is transferred by the head, and the used tape is taken up around the take-up reel, and since the operations are carried out as a series of operations, it is true that in case constituent members associated with the operations are consolidated into a cartridge, the replacement work can be facilitated. However, it is totally a waste to replace many constituent members which function properly together with the used up coating film transfer tape, and such a design can be said as departing from the original object to conserve resources and reduce the amount of wastes to be discharged.
In addition, while there exist among the cartridge type products some products which are simple in construction and hence comprise fewer constituent members, it is often the case with such a product that the replacement work becomes more complicated by an extent to which the number of members to be replaced is reduced.
To cope with this, a technique has been proposed for eliminating the drawbacks inherent in the cartridge type coating film transfer tools.
For instance, an invention such as disclosed in Japanese Unexamined Patent Publication (Kokai) No. 9-2724 is taken for example. As shown in
FIG. 29
, in a coating film transfer tool according to the invention, a transfer head
900
and an arm
901
for supporting the transfer head
900
are provided in such a manner as to rotate together, and as shown in
FIG. 30
, a replacement coating film transfer tape
1001
mounted on a holder
1000
can easily be mounted on the tool. Namely, when replacing coating film transfer tapes the head
900
and the arm
901
are rotated to be put in a state shown in
FIG. 31
, and in this state the replacement coating film transfer tape
1001
fixed to the holder
1000
and a take-up reel
1002
can be mounted on the coating film transfer tool from thereabove. After the tape has been mounted properly, the coating film transfer tape is automatically set relative to the head by rotating the head
900
and the arm
901
in a counterclockwise direction, and at the same time the coating film transfer tape is taken up to eliminate a slack thereon, thus the replacement work being implemented with ease. In many cases, it is the most troublesome to the user with respect to the tape replaceable coating film transfer tool to engage the coating film transfer tape with the head at the time of replacing coating film transfer tapes, but according to the c
