Description

The present invention relates to a tape dispenser of the type in which a coating component to be applied to a paper surface is supported by a ribbon, and in use of the dispenser, the coating component is transferred to the paper surface as a continuous strip while the support ribbon is held by the dispenser. Such tape dispensers are well known and are used, for example, to apply correction components and make corrections to cover writing or typing errors. In these known correction tapes, the tape supply and take-up spools are provided separately in the dispenser casing, and the two spools are connected by a drive mechanism and when pulled from the supply spool to use the tape, Wind up the support ribbon using the take-up spool. In addition, since the rotational speeds of the spools are not the same, some kind of clutch mechanism is required. The provision of the clutch increases the manufacturing costs, which is disadvantageous. In particular, most dispensers are intended to be discarded after the first tape has been used. In addition, when the tape is first manufactured and used, all the tapes are supported by the supply spool, and on the contrary, the supply spool is emptied at the time of final use, and all the supporting ribbons are wound around the take-up spool. The spool requires a large space in the dispenser body that acts as a handle to hold the dispenser during use. As a result, the length of the tape supplied to the dispenser is limited if the body is not large and the dispenser is not bulky and inconvenient. This disadvantage is particularly significant when it is desirable to provide a dispenser with a thin and elongated body so that the dispenser can be held in the same way as holding a pen or marker.
In order to eliminate the above-mentioned drawbacks, the present invention is adapted to accommodate a tape supply consisting of a support ribbon supporting a coating of components to be transferred to the paper and a used support ribbon from which the components have been removed. The tape supply provides a tape dispenser that is held in the form of an elongated reel wound around a pair of spool members that are independently rotatable at intervals.
Most advantageously, the ends of the support ribbon are connected to one another and the used support ribbon is housed in a common reel with the remaining unused tape.
If the elongate reels, eg, spools, have the same diameter, holding the tape supply on an elliptical reel allows longer tapes to be stored in the elongate dispenser than is possible with conventional tape storage configurations. Further, by storing the used support ribbon in a common reel with unused tape, another housing within the housing is provided for receiving the used ribbon, as is the case with prior art dispensers. There is no need to add space. A continuous elliptical reel that removes the tape to feed the applicator head from the inner volume causes the used carrier ribbon to be returned to the outermost volume, usually slipping between the reel layers. Occur. This sliding friction effect relies on the applicator head to control tension with the tape in and out of the tape, thereby eliminating the need for drive and clutch mechanisms between the spools. Another way to control the tape tension is to attach the spools to move toward each other and provide spring means to release the spools.
In order to facilitate a clear understanding of the present invention, it will be described in more detail with reference to the accompanying drawings.
FIG. 1 is a schematic view showing an elliptical spool of a tape.
FIG. 2 is an exploded perspective view of a correction tape dispenser according to the present invention.
Referring initially to FIG. 1, a correction reel is shown as being held in a correction tape dispenser. For example, a tape 1 on which a support ribbon of a predetermined length of plastic or paper and a correction component transferred onto the paper surface by a dispenser are supported is known. In accordance with the present invention, the ends of the support ribbon are joined so that the ribbon forms a continuous loop, and the tape is overlapped around a pair of spaced equal diameter spool members 2,3. Wound into a layer, thereby forming an elliptical reel of tape. As shown in FIG. 2, the elliptical reel as a whole is elongated and is housed in an elongated casing 4 as further described below. A portion of the tape between the inside of the reel and the outermost winding extends out of the casing and onto an applicator head that is used to push the tape against the paper when the dispenser is in use. As shown in FIG. 2, the casing 4 is assembled from two parts for supporting the spindles 6 and 7 with a pair of gaps between them, and the two spool members 2 and 3 are attached to the spindles 6 and 7 for each axis. Supported to rotate independently around. The applicator head 5 protrudes from the front end of the casing, and supports a distal end portion 8 having an edge portion 9 through which the tape passes at the free end. The tape is guided to and from the tip by a pair of guide pins or rollers 10. The casing is a patent application. . . . As described above, it can be adjusted to be rotatable with respect to the applicator head. When the tape is pushed onto the paper surface by the leading edge 9 and the leading edge moves on the paper surface in a direction substantially perpendicular to the edge, the correction coating is transferred from the supporting ribbon to the paper surface and applied as a continuous strip. A new tape is pulled from the supply reel. In the embodiment shown, new tape is pulled from the innermost winding of the reel with the back spool 3. In order to assist in separating the tape from the reel, the spool 3 preferably has a predetermined contour to move the innermost winding coming out of the plane of the reel. The separated tape passes on the spool 2 at the foremost end and passes in the direction of the guide pin / roller 10 before moving to the applicator tip 8. The support ribbon that has passed around the edge 9 of the front end and from which the correction component has been removed is the same by the pair of guide pins / rollers 10 before being sent to the tape reel in the outermost winding near the front spool 2. Be guided to. When the correction tape source is used and the elliptical reel of tape is gradually replaced by the used ribbon, no additional space is required in the casing to accommodate the ribbon.
When the tape is fed from the innermost winding of the elliptical reel, the outer layer moves inward and some slip occurs between adjacent layers. Friction between the slip layers can be used to ensure that the applicator head gets the necessary tension in the tape to control the portion extending around it. The amount of tape retained on the elliptical reel of FIG. 1 is significantly greater than it would be housed in the same number of layers around one cylindrical spool.
