Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a continuous transparent sheet in which a display surface is one surface in which unit transparent sheets are arranged in a row in a detachable manner, and is particularly applicable to overhead projectors (hereinafter referred to as
This invention relates to a continuous transparent sheet suitable for use in OHP.

[Conventional technology]

Conventional transparent sheets with one side as a display surface for displaying prescribed matters by various means such as printing, etc., may have scratches on the surface thereof, making the prescribed matters unclear. There was a drawback. In particular, when used for OPH, even if the predetermined items to be projected are not scratched or chipped, if the display surface has scratches or the like and is projected, the viewer cannot clearly see the predetermined items. The disadvantage was that it was difficult to recognize.

Conventionally, in order to solve this problem, as shown in FIG. 3, a protective paper 12 of the same size is superimposed below a continuous transparent film 11 that can be freely separated, and both the transparent film 11 and the protective paper 12 are coated. , there has been proposed a sheet provided with a transfer hole portion having transfer holes 15 and 16 connected to each other through separation perforations 13 and 14 (Japanese Patent Laid-Open No. 59-98897).
(see issue).

[Problem that the invention attempts to solve]

However, in the above proposal, when the transparent film 11 and the protective paper 12 are cut into unit pieces, the two are simply overlapped.
Since they do not have any integrity, they tend to separate from each other, making it extremely inconvenient to handle, and they are not sufficiently protected before being used in OPH.
Furthermore, when the separated transparent film 11 is placed on top of another sheet displaying the upper side, the displayed information overlaps with each other and is difficult to visually recognize. Further, since the transport holes 15 and 16 are provided in both the transparent film 11 and the protective paper 12, and the transport holes 15 and 16 are engaged with the feed pins while the two are overlapped, the transparent film 11 and the protective paper 12 are transported for printing. Since the film 11 lacks flexibility, its conveyance lacks smoothness, and the separation perforations 13 and 14 are also provided on both sides, so that the transparent film 1
1 had the disadvantage that the cutter for forming the perforations 13 was severely worn out.

The object of the present invention is to provide a continuous transparent sheet that can be separated freely and eliminates these drawbacks. Here, in order to eliminate the first drawback, the transparent film 11 and the protective paper 12 should be releasably glued together, but if the adhesive remains on the transparent film 11 side when both are peeled off, This will create a new drawback that will hinder subsequent handling.
The present invention was made taking this point into consideration.

[Means for solving problems]

To achieve this objective, the present invention provides a continuous transparent sheet in which unit pieces are separated and arranged in series along perforations, one side of which is used as a display surface for printing or printing, and the unit pieces of the continuous transparent sheet as well as the One end of the continuous transparent sheet along the continuous direction is releasably adhered to the peeling surface on the side opposite to the display surface of the continuous transparent sheet so that each piece can be separated from the separation perforation corresponding to the separation perforation. A continuous sheet of paper is provided with a pair of transport holes extending from both ends along the flow direction of the sheet.

[Effect]

Even if the continuous transparent sheet is made into a single piece, it will not separate from the continuous paper, and the conveyance during printing or printing will be smooth as only the transport hole of the continuous paper needs to be engaged with the feed pin. Since there is no need to form transfer holes or perforations, manufacturing is also facilitated.

Furthermore, since the continuous transparent sheet and the continuous paper are releasably bonded at one end along the continuous direction, when checking the printed content on the continuous transparent sheet, it is possible to Even if it is difficult to see due to the degree of color difference between the continuous transparent sheet and the continuous paper, a sheet of any color can be inserted between the continuous transparent sheet and the continuous paper.
It is easy to check the contents of printing etc.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described as shown in the attached drawings.
This will be explained in detail based on the figures and FIG.

Here, FIG. 1 is a schematic plan view showing a part of a continuous transparent sheet, and FIG. 2 is an enlarged sectional view thereof.

As shown in FIG. 1, the continuous transparent sheet 1 is
Each unit piece 1a is arranged in a row so that it can be separated freely via a separation perforation 2 which also serves as a folding perforation, and its surface constitutes a display surface 3 on which predetermined information is displayed by printing or other means. .

As is clear from FIGS. 1 and 2, each unit piece 4a of the continuous paper 4 is separated through a separation perforation 5 which also serves as a folding perforation and is formed to correspond to the separation perforation 2. While the continuous transparent sheet 1 is freely connected, it is releasably adhered to the back surface opposite to the display surface with an adhesive 6 so that it can be separated into unit pieces 1a and 4a together with the continuous transparent sheet 1. The adhesive 6 is applied to the continuous paper 4 so as to be interposed in a band shape at one end along the flow direction of the continuous transparent sheet 1, and is always sticky under normal conditions; is weak, and if a predetermined repelling force or more is applied, the continuous paper 4 will be peeled off from the continuous transparent sheet 1. Further, the continuous paper 4 is provided in a pair of transfer holes 8 which are provided through separation perforations 7, respectively, so as to extend from both ends of the continuous transparent sheet 1 along the flow direction.
It is equipped with Each of these transfer hole portions 8 is provided with a large number of transfer holes 9 at predetermined intervals in the flow direction.

Since the present embodiment is configured as described above, the transport hole 9 of the continuous paper 4 is engaged with the feed pin, the continuous paper 4 is transported together with the continuous transparent sheet 1, and predetermined information is printed on the display surface 3 of the continuous transparent sheet 1 by the printer. can be performed continuously. In this way, it is only necessary to engage the continuous paper 4 with the transport mechanism during the transport operation, and there is no need to engage the continuous transparent sheet 1. Therefore, there is no difference from a general paper transport operation, and the operation can be carried out smoothly. It is possible to do so. After printing, after cutting the pair of transfer holes 8 of the continuous paper 4 at each separation perforation 7, the continuous transparent sheet 1 and the continuous paper 4 are separated into each unit piece 1a, at each separation perforation 2, 5. While it is possible to separate each unit piece 4a, even if the unit pieces 1a and 4a are separated, they will not separate because each unit piece 1a, 4a is bonded. Each unit piece 1a, 4a in the adhesive state can be easily peeled off as needed, and after peeling off, the adhesive 6 remains on the unit piece 4a side.

In addition, since the continuous transparent sheet 1 and the continuous paper 4 are releasably adhered at one end along the continuous direction, when checking the content printed or printed on the continuous transparent sheet 1, the color of the printing etc. Even if it is difficult to see due to the degree of color difference between the continuous transparent sheet 1 and the lower continuous paper 4, it is possible to insert a sheet of any color between the continuous transparent sheet 1 and the continuous paper 4, making it easy to check the printed contents. It has the advantage of being easy.

Note that the present invention is not limited to the embodiments described above, and for example, the position where the adhesive 6 is provided is
The continuous transparent sheet 1 may have a band-shaped portion along each tearing perforation 2, or a portion corresponding to the entire surface or almost the entire surface of the continuous transparent sheet 1. Also, the back surface of the continuous transparent sheet 1 may be provided with a strip to facilitate peeling. Furthermore, if the display surface 3 of the continuous transparent sheet 1 has poor writability for printing, printing, etc., it may be processed into a mat shape. Many modifications can be made, such as that the separation perforation 7 for separating the transfer hole 8 is not necessarily necessary.

[Effects] As is clear from the above explanation, according to the present invention, even if the continuous transparent sheet and continuous paper are separated into unit pieces, they remain glued at one end, so they can be handled easily without separating from each other. It is convenient, and if necessary, the two can be easily peeled off by using the unbonded part on one end as a finger grip, and after peeling off, no adhesive remains on the continuous transparent sheet side, which does not cause any trouble in subsequent handling. Printing on a continuous transparent sheet or transferring it during printing can be done smoothly because only the continuous paper needs to be engaged with the feed pin.Furthermore, since there are no transfer holes in the continuous transparent sheet, it is easy to separate the continuous sheet. Since perforations are not required, manufacturing is facilitated, and furthermore,
The continuous transparent sheet and continuous paper are releasably glued at one end along the continuous direction.
When checking the printed content on a continuous transparent sheet, even if it is difficult to see due to the degree of color difference between the printed color and the continuous paper below, it is possible to print any color between the continuous transparent sheet and the continuous paper. Since the sheet can be sandwiched between sheets, it is possible to have many beneficial effects such as easy confirmation of the contents of printed characters and the like.
