Abstract

PURPOSE:To easily and accurately bond the leading end part of an ink sheet roll by displaying a guide mark showing the bonding position at the leading end part of the ink sheet roll to the cylindrical surface of a take-up core. CONSTITUTION:A guide mark 5 is linearly displayed on the cylindrical surface of a take-up core 2b in parallel with the axis of the core 2b. When an ink sheet roll 1 is bonded to the take-up core 2b, the leading end of a guide tape 5 is matched with the guide mark to be bonded to the core 2b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an ink sheet roll used in a thermal line printer, and particularly to a winding core thereof.

[Conventional technology]

FIG. 4 shows an ink sheet roll set used in this type of printer. In the figure, 1 is an ink sheet whose base material is a thin film of polyester film and the surface of which is coated with thermal transfer ink LA; 2a; 2b is a pair of supply-side core and winding core for winding the ink sheet 1, and the terminal end of the ink sheet 1 wound around the supply-side core 2a is provided with a winding core for transporting the ink sheet 1. An adhesive tape 3 that prevents unraveling and enables attachment to the winding core 2b is connected to an edge tape 4 that facilitates peeling off the adhesive tape.

When installing the ink sheet roll set having the above structure into a printer, from the state shown in FIG. 4, the adhesive tape 3 is peeled off from the ink sheet 1 by pulling the edge tape 4 and pasted onto the winding core 2b.

[Problem to be solved by the invention]

However, when the tip is peeled off as described above, since the ink sheet 1 is a thin film of several microns to several tens of microns, it is difficult to handle after unwinding, and the winding core 1
It was difficult to attach it parallel to the central axis of b. At this time, the ink sheet that is not pasted in parallel causes a difference in the tensile force on the left and right sides of the ink sheet 1, as shown in Figure 5, which causes the ink sheet to sag on the loose side, causing curling and wrinkles. Ta.

Therefore, as a means to solve the above problems, for example,
215078, it has been proposed to attach a winding core to the ink sheet roll at the time of shipment, but with such a product, the winding core is always attached to one roll of ink sheet. It is necessary to supply two bottles, which has the disadvantage of high cost.

This invention was made in order to solve the above-mentioned problems, and when pasting an ink sheet to a winding core, the pasting position can be easily judged, and the pasting does not cause wrinkles on the ink sheet. The purpose is to make it possible to paste without any problem.

[Means to solve the problem]

The winding core according to the present invention has a guide mark for positioning the leading end of the ink sheet displayed on the side surface of the cylinder.

[Effect]

On the cylindrical surface of the winding core according to the present invention, a guide mark indicating the position of the tip of the ink sheet is displayed, so that it can be attached easily and accurately by aligning the tip side with the guide mark. It will be done.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of a winding core according to the present invention, and FIG. 2 is a perspective view showing a state in which an adhesive tape is attached to this winding core.

Reference numeral 5 in FIG. 1 is a guide mark (alignment mark) displayed linearly on the cylindrical surface of the winding core 2b parallel to the central axis, and the mark affixed to the tip of the ink sheet 1 indicates the position. It is.

Therefore, the ink sheet roll 1 is wound on the winding core 2b.
When pasting the ink sheet 1 and the winding core 2b, the ink sheet 1 and the winding core 2b can be pasted in a predetermined positional relationship by aligning the tip of the gripper 14 with the guide mark 5.

As described above, since the adhesive tape 3 is attached by aligning the edge tape 4 at the tip of the ink sheet roll 1 side with the guide mark 5 on the winding core 2b, the left and right sides of the ink sheet 1 are pulled uniformly, causing winding wrinkles. It becomes something that does not.

In the above embodiment, only one guide mark 5 is displayed, but multiple guide marks 5 may be displayed as shown in FIG. 3a. If it is smaller, left and right alignment marks 5a and 5b may be displayed as shown in FIG. By displaying this guide mark on both the long winding cores 2a and 2b, it is not necessary to attach the two winding cores in advance at the time of factory shipment, and both product cost and transportation cost can be reduced.

〔Effect of the invention〕

As described above, according to the present invention, the ink sheet can be correctly pasted simply by displaying the alignment mark on the surface of the winding core, so no wrinkles occur and the workability of installing the ink sheet into the printer is greatly improved. It has the effect of improving

[Brief explanation of drawings]

1 and 2 show an embodiment of the present invention. FIG. 1 is a perspective view showing only the winding core, and FIG. 2 is a perspective view of the winding core shown in FIG. FIGS. 3a and 3b are perspective views of a winding core according to another embodiment of the present invention, FIG. 4 is a perspective view of a conventional ink sheet roll set, and FIG. FIG. 2 is a perspective view showing the drawbacks of the conventional example. In the figure, 1 is an ink sheet, 2a is a supply-side core, 2b is a winding core, 3 is an adhesive tape, 4 is a pick-up tape, and 5 is a guide mark. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Claims] An ink sheet having an adhesive tape and a tear-off tape connected to the terminal end thereof, and a supply core and a winding core around which the ink sheet is wound, wherein the cylindrical surface of the winding core is An ink sheet roll set characterized in that a guide mark for positioning when pasting the terminal end of the ink sheet is displayed on the top thereof in parallel to the central axis of the ink sheet roll set.
