ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a coat film transfer tape cartridge and a coat film transfer tool, and more particularly to a refill type coat film transfer tape loading technique for replacing a coat film transfer tape in a coat: film transfer tool for transferring correction paint layer, marker paint layer, adhesive layer or other coat film on a coat film transfer tape onto the sheet of paper or the like.
2. Description of the Related Art
The coat film transfer tool of this kind is disclosed, for example, in Japanese Patent Laid-open Publication No. 5-58097 and Japanese Utility Model Laid-open Publication No. 5-13800.
These coat film transfer tools are both used as an eraser for correcting wrong letters, and as shown in FIG.
35
(
a
) and FIG.
35
(
b
), a pay-off reel (c) on which a coat film transfer tape (b) is wound, and a take-up reel (d) for collecting the used coat film transfer tape (b′) are rotatably provided in a case (a) which is held by one hand, and a coat film transfer head (f) for pressing the coat film transfer tape (b) onto the object of transfer (the correction area on the sheet of a paper) (e) is projecting from the leading end portion of the case (a) The both reels (c), (d) are automatically taken up as being linked mutually through an interlock unit (g) so as to cooperate. In the interlock unit (g), gears (h), (i) provided on the outer circumference of the both reels (c), (d) are engaged with each other.
The case (a) is a flat box having the contour shape and width dimension enough for incorporating the pay-off reel (c) and take-up reel (d), and the face and back of the flat shape, that is, the face and back to the sheet of paper in FIG.

(

) are the gripping sides when held by hand during use.
In the coat film transfer tool in FIG.
35
(
a
), the leading end pressing portion (j) of the head (f) is designed to guide the coat film transfer tape (b) in a winding state of the pay-off reel (c) and take-up reel (d), and it is also-called vertical pulling structure suited to correction of a part of vertically written letters such as Japanese sentences. On the other hand, in the coat film transfer tool shown in
FIG. 35
(
b
), the leading end pressing portion (j) of the head (f) is designed to guide the coat film transfer tape (b) almost oppositely to the gripping sides of the case (a), and it is a so-called lateral pulling structure suited to correction of a part of laterally written letters alphabetic sentences.
When correcting wrong letters by these coat film transfer tools, the gripping sides of the case (a) are held by fingers, the coat film transfer tape (b) is held tightly on the correction area (e) by means of the leading end pressing portion (j) of the head (f), and the case (a) is moved in a desired direction (arrow direction in
FIG. 35
(

); vertical direction to sheet of paper in FIG.
35
(
b
)). As a result, the correction paint layer of the coat film transfer tape (b) at the leading end pressing portion (j) of the head (f) is applied on the correction area (e) and the letter is erased, and the used coat film transfer tape (b′) is automatically taken up and collected on the take-up reel (d).
Recently, on the other hand, an effective use of resources of the earth is particularly demanded, and from the viewpoint of saving of resources, in this kind of coat film transfer tool, it is desired to employ a so-called refill type structure for replacing only the consumable part of coat film transfer tape (b).
From such viewpoint, lately, various replaceable tape cartridges provided in the case (a) are proposed. The tape cartridge as the consumable part is generally classified into a structure comprising four parts, coat film transfer tape (b), pay-off reel (c), take-up reel (d), and head (f), and a structure comprising three parts, coat film transfer tape (b), pay-off reel (c), and take-up reel (d)
In the tape cartridge of either structure, however, all components are put in a plastic container, and they are replaced entirely together with the used tape cartridge, and in particular the plastic container is relatively large filling up the inner space of the case (a) of the coat film transfer tool, and the rate of occupation of the materials in the entire device is large, and the structure has been demanded to be reduced in weight and simplified.
The conventional tape cartridge further comprises a member (not shown) for stopping rotation of the pay-off reel (c) and take-up reel (d) until being loaded into the case (a), and this rotation stopping member is discarded as refuse after loading the tape cartridge, and this point must be also improved from the viewpoint of saving of resources.
SUMMARY OF THE INVENTION
It is a primary object of the invention to present a novel tape cartridge for a coat film transfer tool solving the problems of the prior art.
It is other object of the invention to present a tape cartridge having a support body of lightweight and simple structure, and capable of replacing the coat film transfer tape easily and promptly, by improving the structure of the refill type coat film transfer tool.
It is a further object of the invention to present a coat film transfer tool comprising such tape cartridge, and having a small, simple, and inexpensive structure that can be used like a writing tool flexibly depending on the manner of holding of a writing tool of an individual user.
A first tape cartridge of the invention is a tape cartridge for coat film transfer tool replaceably loaded in a case of a coat film transfer tool, the coat film transfer tool comprising a pay-off reel having the coat film transfer tool and a take-up reel for collecting the coat film transfer tape after use, both rotating in cooperation, and further a coat film transfer head for pressing the coat film transfer tape on a transfer area, in which at least the rotatable pay-off reel having the coat film transfer tape and the rotatable take-up reel for collecting the coat film transfer tape after use are provided on a support body, this support body has a support base plate for rotatably supporting the opposite side ends of rotary shafts of both reels supported detachably and rotatably on a rotary support shaft of the case, and this support base plate has a flat skeletal structure having an outer contour corresponding to the inner contour of the case.
Preferably, the skeletal structure of the support base plate is composed of an outer contour skeletal member forming the outer contour of the support base plate, a bearing skeletal member forming the bearing for rotating and supporting the rotary shaft of the reel, and a connection skeletal member for connecting the both skeletal members, which are connected in a flat skeletal structure. The connection skeletal member is formed as being extended in the radial direction from the bearing.
Further, on the outer peripheral edge of the support base plate, a protective wall is integrally formed upright for surrounding and protecting the both reels, and the support base plate and protective wall may be combined to form a cartridge case for surrounding and holding three sides of the both reels, and in this case the cartridge case composed of the support base plate and protective wall is preferred to be formed in one piece made of synthetic resin. In other preferred structure, on the outer circumference of the protective wall, there is an engaging part to be engaged with a positioning engaging part provided in the inner circumference of the case of the coat film transfer tool, and when the tape cartridge is put in the case of the coat film transfer tool, the both reels are rotatably supported on both sides by the rotary support shaft and support base plate of the case.
Also preferably, at least one of the two reels is provided with a clutch mechanism for synchronizing the pay-off speed and take-up speed of the coat film transfer tape in the both reels, and this clutch mechanism specifically comprises a cylindrical tape core on which the coat film transfer
