Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink ribbon cassette used in printing devices such as typewriters and teleprinters, and particularly to an endless ink ribbon for refilling endless ink ribbon cassettes that do not require rewinding of the ink ribbon.

More specifically, the present invention relates to a refillable endless ink ribbon that is inexpensive, easy to refill, and applicable to cassettes of various shapes.

Endless ink ribbon cassettes used in printing devices such as typewriters and teleprinters have been increasingly used in recent years because they are easy to handle when replacing them and do not require a rewinding mechanism for the printing device.

However, since it was made into a cassette, the price per print increased.

Furthermore, since the length of the ink ribbon is limited, the printing life is short and the cassette must be replaced frequently.

Therefore, a method of refilling only the internal endless ink ribbon began to be adopted.

Endless ink ribbon for refilling was made in 1977-12.
There was one that used the plastic case presented at 270, and another that used a thinly rolled endless ink ribbon.

However, in the former case, the case is made from a plastic injection molded product and the case is folded irregularly inside the case, so the case itself is expensive and the case must be molded for each of the various cassettes, which is very complicated.

Another problem is how to dispose of the case after use.

Furthermore, since the endless ink ribbon is folded irregularly, it has the disadvantage that the volume of the endless ink ribbon becomes large.The latter solves all the disadvantages of the former, but after being packed into a cassette, the endless ink ribbon runs. However, since only one side of the thinly wound ink ribbon comes out of the cassette, the other remains inside the cassette, which has the fundamental drawback that in most cases the ribbon gets jammed at the cassette exit. Ta.

The present invention relates to a completely new refillable endless ink ribbon that does not have these drawbacks.

In the present invention, a pressing member having approximately the same shape as the surface when bundled is placed on the surface formed by the ears of an endless ink ribbon folded to a substantially constant length A, leaving the loop portion,
When a binding tape that is folded in half in the long side direction with a width slightly shorter than A is laid under the endless ink ribbon, the direction in which the endless ink ribbon is folded is the long side direction of the binding tape that is folded in half. Refillable endless ink ribbon, characterized in that the tape is folded in half and the upper end of the binding tape is then glued to a pressing member, and the ribbon is then wrapped by gluing from above. .

The present invention will be explained with reference to the drawings.

Fig. 1 is a schematic sectional view of the endless ink ribbon for refilling of the present invention, Fig. 2 is a perspective view of the endless ink ribbon before bundling, and Fig. 3
The figure is a perspective view of the product after it has been bundled.

An endless ink ribbon 1 is folded to a substantially constant length A leaving a loop part 2, and a pressing member 4 is placed on a surface 3 formed by the ears.

The holding member 4 preferably has a rectangular shape that is approximately the same shape as the surface 3 formed by the ears when the folded endless ink ribbon 1 is bundled, and is made of a material capable of holding the ink ribbon, such as pole paper or plastic sheet. Good to have.

Next, the folded portion of the endless ink ribbon 1 is bundled with the binding tape 5. The width of the binding tape 5 is a little shorter than the folded length A of the endless ink ribbon 1, and it is folded in half in the direction of the long side of the waist. Make it.

The folded part of the endless ink ribbon 1 is placed on the binding tape 5 which has been folded in two.

At this time, the direction in which the endless ink ribbon 1 is folded and overlapped is made to be the same as the long side direction of the bundle tape 5 folded in half.

Next, the upper end 6 of the bundle tape 5 folded in half is adhered to the pressing member 4.

Further, the lower end 7 of the bundle tape 5 is adhered to the folded part 8 of the bundle tape 5 so as to be wrapped from above, thereby performing bundle packaging.

The loop portion 2 of the endless ink ribbon 1 is preferably placed outside the bundle packaging.

In the above manner, the refillable endless ink ribbon of the present invention is manufactured.

Next, the procedure for refilling the cassette will be explained.

FIG. 4 is a perspective view of the cassette being refilled with the refillable endless ink ribbon of the present invention.

First, remove the endless ink ribbon whose print density has already become lighter from the cassette.

Next, the refillable endless ink ribbon of the present invention is put into the cassette, and the loop part 2 passes through the outlet part 9, the inlet part 10, and the ink ribbon feeding roller part 11 of the cassette.

Next, remove the adhesive between the end 7 of the bundle tape 5 and the end 8 of the bundle tape 5 that is folded in half, and while lightly pressing the presser member 4, pull out the end 7 of the bundle tape 5 upward. The binding tape end 8, which is the end, gradually becomes shorter as it slips between the cassette case and the endless ink ribbon and is pulled out.

Since the entire binding tape 5 that holds the endless ink ribbon is pulled out, and the end 6 of the binding tape 5 is adhered to the presser member 4, a series of operations that pull up the end 7 of the binding tape 5 are performed. The holding member 4 can also be removed from the top of the endless ink ribbon housed in the cassette case.

Without the holding member 4, the endless ink ribbon would overflow from the cassette when the binding tape 5 was removed from the cassette.

Once the endless ink ribbon overflows, it is impossible to dispose of it.

If the binding tape 5 is made of a stiff and tensile-resistant film such as a polyester film with a thickness of about 25μ, the endless ink ribbon will not form a bundle, and the length of the ribbon will be slightly shorter than the folded length A. Because of its width, the bundled endless ink ribbon can be packed into the cassette without falling out.

Also, since it is folded in half, there is a bundle tape 5 inside the cassette.
There is no longer any possibility that foreign objects such as scraps of ink could interfere with the running of the endless ink ribbon.

In addition, the volume is smaller and more compact than an irregularly folded endless ink ribbon, and since an injection molded plastic case is not used, it can be used to refill various cassettes.

As described above, the present invention completely transfers only the endless ink ribbon into the cassette case in one operation, leaves no parts left behind to bundle and hold the endless ink ribbon, and is inexpensive and refillable. This is an innovative refillable endless ink ribbon that is simple and can be applied to a variety of cassettes.

Claims (1)

[Scope of utility model registration request] On the surface formed by the ears of an endless ink ribbon that has been folded to a substantially constant length A with the loop section remaining, place a presser member that has approximately the same shape as the surface when it is bundled, and hold it slightly shorter than A. When the binding tape folded in half in the long side direction with the width of the paddle is laid under the endless ink ribbon, the folding direction of the endless ink ribbon is the same as the long side direction of the binding tape folded in half. Then, the upper end of the folded binding tape is glued to the pressing member, and then the lower end of the binding tape is glued from above the folded part of the binding tape. A refillable endless ink ribbon characterized by being packaged.
