Description

[Detailed description of the invention] This invention relates to the improvement of label forms used in non-impact printers, and prevents adhesive from adhering to the hole feed section and other parts of the printer that come into contact with the form paper. With,
The present invention relates to a label form for a non-impact printer that can improve work efficiency by preventing toner from adhering to fusing rollers, etc.

Conventionally, label forms used in printers, which are one of the output devices of computers, can be broadly classified into the following two types. That is, [1] As shown in Figure 1 A, B, and C, the adhesive paper a is removed from the portion 2 other than the portion 1 that will become the label.

[2] In Figure 2, as shown in A, B, and C, just put a blade shape on adhesive paper a in the shape that will become a label.
Other parts are left as is.

There are two types. Of these two types, only the type described in [1] can be used in non-impact printers, which have become rapidly popular in recent years, and the type described in [2] This product cannot be used because it causes the following problems. That is, in the case described in [2], the adhesive b is pushed out to the surface from the perforations provided for folding and adheres to the printer. Similarly, adhesive b comes out from the left and right sprocket holes and adheres to the printer. Therefore, if a large amount of paper is used in this state, a large amount of adhesive b will adhere to the contact area of the printer, forcing cleaning work, and in the end, the original purpose of rapid data processing will not be possible. It becomes possible. For this reason, the type described in [2] is hardly used at present, and most non-impact printers currently used are the type described in [1]. It's just something. However, although the type described in [1] does not cause the adhesive b to protrude, depending on the type of non-impact printer, new problems such as those described below may occur and a large amount of processing is required. may become impossible. The present invention provides a label form that is also suitable for such printers. The structure of this type of non-impact printer and the problems that occur when the label form described in [1] above is used in the printer are as follows.

That is, the outline of its structure is as shown in FIG. 3. Light 4 such as a laser beam is irradiated onto a photosensitive drum 3 whose main materials are selenium and zinc oxide to convert information such as data into electric charges. Toner 5 is attached to the charges for development. This developed toner 5 is
The transfer is performed on the form paper 7 at the part shown in FIG.
One method is to use corona discharge to ionize the air and use its electric force to attract toner. Next, the toner is melted by a fusing roller 8 at about 200° C. to fix the toner 5 to the surface of the form paper 7.

In the above description, the photosensitive drum 3 contains, during development,
The reality is that a small amount of toner 5 is scattered over almost the entire surface of the blank area other than characters, etc., and almost all of the toner 5 is in the area 6 of the form paper. The actual situation is that it is transferred to 7. Therefore, when the label form [1] above is supplied as the form paper 7,
The part where the adhesive paper a is removed and the release paper c is exposed, that is, the part 2 other than the part 1 that will become the label
Naturally, the toner 5 is also transferred to the surface. On the other hand, the surface of the release paper c from which the adhesive paper a has been removed is coated with silicone so that no adhesive b remains. That is, in the area where the adhesive paper a has been removed, the toner 5 is scattered on the silicon coated on the release paper c. When the toner 5 in such a state goes to the fusing roller 8, the toner 5 on the silicone does not fuse to the release paper c, but instead adheres to the fusing roller 8. Here, if there is even a small portion of the adhesive paper a in the vertical direction of the form paper 7, this toner 5 is transferred to the adhesive paper a little by little. However, if there is not enough adhesive paper a, or if there is no part of adhesive paper a in the vertical direction as in the marginal punch section M shown in FIG. increases to Therefore, this phenomenon in which the amount of adhered toner 5 increases is as follows.
When the amount reaches a certain level, the form paper 7
The entire toner 5 may be rolled up by the fusing roller 8, or the toner 5 on the fusing roller 8 may aggregate and fall onto the form paper 7, staining the form paper 7. This drawback of the conventional label form described in the present invention [1] is eliminated.

An embodiment of the present invention will be explained with reference to the drawings. Figure 4A is a plan view of a label form for a non-impact printer according to the present invention, Figure 4B is a sectional view taken along line X-X' of Figure 4A, Figure 4 C is Y- in Figure 4 A.
It is a sectional view taken along the Y′ line, and shows a peripheral portion 11 of the feed hole 10.
The adhesive paper a is not provided and only the release paper c is used, and in the intermediate part between the peripheral parts 11 and 11, there is a part 12 where the adhesive paper a is provided and a part 14 where it is not provided until the edge 13 of the form paper 7 is reached. It has been established that

In this embodiment, the peripheral portion 11 surrounding the feed hole 10 and the portion 14 where the adhesive paper a is not provided are both rectangular so as to reach the edge 13 of the form paper 7. Therefore, the portion 12 provided with the adhesive paper a
is also rectangular in shape.

The present invention has the above-mentioned configuration, and since a part is provided in the peripheral part 11 of the feed hole 10 where the adhesive paper a is not provided, the adhesive b does not protrude and adhere to the machine.
Since the portion 12 having the adhesive paper a is provided between the peripheral portions 11 and the peripheral portion 11 until it reaches the edge 13 of the form paper, the toner 5 does not adhere to the fusing roller 8, and a non-impact type This allows the printer to print label forms at high speed.
