Abstract

PURPOSE:To reduce the stacked height of a fanfold-type two-ply thermal recording paper and facilitate release of two sheets from each other after cutting by providing a slit in a part of a top sheet on the hind side of a perforation so as to diagonally intersect the perforation. CONSTITUTION:A two-ply thermal recording paper 1 drawn out in the direction of an arrow A comprises a top sheet 11 and a bottom sheet 12, which are lightly adhered to each other by an adhesive layer 13. For every predetermined length (e.g., a length corresponding to one sheet of receipt), the recording paper 1 is provided with a perforation 14 for enabling folding thereat, by providing the paper with cuts penetrating the two sheets in the form of a dotted line orthogonal to the continuation direction of the paper. The top sheet 11 is provided, on the hind side of the perforation 14, with a slit 15 diagonally intersecting the perforation 14, thereby cutting a part of the width of the paper. The recording paper 1 is stacked by folding it in the manner being fan-folded at the positions of the perforations 14, and is contained in a recording paper storage casing. Thus, the height of the recording paper in storage is reduced, the top sheet will not be turned up in a drawer, and release of the two sheets from each other is facilitated.

Description

[Detailed Description of the Invention] [Summary] It relates to thermal recording paper for thermal printers, and in particular thermal paper that can be stacked and printed on two sheets at the same time.
The purpose of this paper is to provide a thermal paper that can be easily peeled off, and a bottom sheet and a top sheet, each of which is thermosensitively colored, are stacked one on top of the other, and perforations are formed at regular intervals perpendicular to the length direction. The thermal paper is folded and has a structure in which a slit is provided in a part of the top sheet so as to cross diagonally to the perforation on the rear side of the perforation.

[Industrial application field]

The present invention relates to thermal recording paper for thermal printers, and more particularly to 2PLY thermal recording paper that allows printing on two sheets at the same time.

Thermal printers that print on thermal paper using heat have a simple mechanism, can be made compact, are maintenance-free, and have a long lifespan. For this reason, these printers have recently come to be used as in-vehicle printers for printing receipts in card fare payment systems for paying transportation fares using prepaid cards, membership cards, and the like.

However, when installing this printer in a small passenger car such as a taxi, it is necessary to store the recording paper in a limited space such as a dash board, so thermal recording paper that takes up a small space and is easy to handle is required. Ru.

[Conventional technology]

FIG. 2 is a schematic diagram showing an in-vehicle card processing device in a card fare system.

The card processing device 2 includes a card reading section, a sales data storage section, etc., as well as a thermal printer 21 for issuing receipts.
For example, in the case of a taxi, it is attached to the dash board in front of the driver's seat of the passenger car 3.

As this printer, a thermal printer 21 which is small and lightweight and does not require maintenance is used, and a predetermined number of consecutive receipt sheets of thermal paper 4 are set under the thermal printer 21.

Then, the driver cuts off a portion 5゛ of the length of one receipt that has passed through the inside of the thermal printer 21 and has predetermined information printed on it using a manual cutter 21a installed at the receipt outlet of the thermal printer 21. Then hand it to the customer.

By the way, if a roll of thermal paper 4 in which a predetermined number of receipt papers are continuously rolled up is used as this paper, the height (
There is a drawback that the roll diameter is too large to be accommodated in the dash board and it gets in the way of the passenger 31 in the front seat.

Therefore, as shown in Figure 3, if you use fan-fold type thermal paper 5 that folds each part of the receipt for cents, the depth dimension will increase compared to roll type 4 even with the same number of sheets of continuous paper. However, this method was adopted because the height was very low and it was possible to store the paper inside the dash board.

In this case, the paper is stored inside the paper storage case 22 below the thermal printer 21, and as the printer prints, it is pulled out in a direction substantially parallel to the folded paper surface and fed to the thermal printer 21. Ru.

By the way, it is necessary to print two receipts at the same time, one for the customer's hand and one for the driver's copy, and the thermal paper for this is the fourth one.
As shown in Figure (a), 2PLY thermal paper 5 is used, in which two sheets of thermal paper, a bottom sheet 52 and a top sheet 51, are overlapped and lightly adhered, and one of the receipts printed and canted in two layers is used. The driver peels off the card and hands it to the customer.

In order to facilitate this peeling, a slit 53 is made in the top sheet 51 near the cutting line C over the entire width of the paper, and the bottom sheet 52 is cut into pre-cut lengths. It is glued and the fourth
As shown in Figure (b), after cutting at position C, the edge of the top sheet 51 is peeled off from the bottom sheet 52 by bending the scorpion part, so peeling can be easily performed using that part as a starting point.

[Problem to be solved by the invention]

FIG. 5 is a diagram showing conventional problems.

Conventional 2FLY thermal paper has a slit (cut) across the entire width of the top sheet, so if it is squeezed with a small radius of curvature, the two sheets will separate before being fed into the printer, and the paper will not be fed to the printer in a 2PLY state. There is a problem.

That is, as mentioned above, it is necessary to store the paper in a narrow space, so it is necessary to make the height of the paper storage case 22 as low as possible, and for this reason, the folded thermal paper 5 is pulled out in a direction substantially parallel to the paper surface. There is.

Therefore, when the thermal paper 5 is pulled out, the paper storage case 22
Since the top sheet 51 is squeezed with a small bending radius as shown in B in the narrow space between the top cover 22a and the top cover 22a, a problem arises in that the top sheet 51 separates from the bottom sheet 52 before printing and is not properly fed to the printer.

The present invention was created in view of the above-mentioned problems, and an object of the present invention is to provide a fan-hold type 2PLY thermal paper that has a low stacking height and that allows two sheets to be easily separated after being canted.

[Means for solving the problem] The above problem is caused by the fact that a bottom sheet and a top sheet, each of which is thermosensitively colored, are overlapped and folded at perforations provided at regular intervals and perpendicular to the length direction. Solved by the thermal paper of the present invention, which is characterized in that a slit is provided in a part of the top sheet so as to cross diagonally to the perforation on the rear side of the perforation. be done.

[For production]

Since the top sheet is connected at the perforation, even if the top sheet is pulled out with a small curvature in the direction of the folded paper surface, it will not peel off from the bottom sheet, and the paper will be fed smoothly to the thermal printer. Then, after printing, the diagonal cut portion of the top sheet that is canted at the perforation position (folding position) is slightly separated from the bottom sheet, so using this as a clue, it becomes possible to easily separate the bottom sheet and the top sheet.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

2PL pulled out in the direction of arrow A in figure (a)
The Y thermal paper 1 consists of a top sheet 1 and a bottom sheet 12, and the top sheet 11 has a top sheet thermal layer 11a.
and paper 11b. Further, the bottom seam 2 is made up of a bottom sheet heat-sensitive layer 12a and a paper 12b. The top sheet 11 and the bottom sheet 12 are lightly adhered to each other by a wax-based adhesive layer 13 and are in close contact with each other.

Then, perforations 14 are provided for each predetermined length (e.g., receipts - autumn equinox) to enable close folding. On the rear side of 14, the top sheet 11 has a slit 15 diagonally intersecting the perforation 14.
A part of the paper width is cut off by

17 is a position detection mark, which is printed in advance on the rear side of the perforation 14 on the top seam 1 and outside the receipt printing area 16 by the printer, and is detected by a sensor inside the printer to control the paper feed. , perforation 14 after printing
is adapted to stop at the position of the manual cutter 21a.

As shown in FIG. 2B, the continuous paper sheets are folded into a folding screen shape at the perforations 14, stacked, and stored in a recording paper storage case.

In this case, the perforation 14 at the folding position makes it possible to make the bending radius of the folding portion extremely small, and even if a predetermined number of sheets are stacked, it is sufficient to stack only the thickness of the paper, and the storage height can be reduced.

As the pudding printing progresses, even if the top sheet 51 is pulled out with a small bending radius between the top cover of the storage case and the paper surface, the top sheet 51 remains connected to the perforation part from most of the paper width, and the slit 14 Since the top sheet is formed diagonally from the position of the perforation 14 so as to widen toward the rear from the connecting portion, the top sheet is not rolled up and is supplied to the printer in a two-layered state.

Then, by bending the slit position of the two-sheet receipt cut at the perforation position after printing, the edge of the top sheet can be peeled off from the bottom sheet as in the conventional example, and using that part as a starting point, the top sheet can be removed from the bottom sheet. The sheet and bottom sheet can be easily peeled off and separated into two pieces.

〔Effect of the invention〕

According to the present invention, it is possible to provide a fan-hold type thermal paper that has a low stacking height and that can be easily separated into two sheets after being canted, contributing to the miniaturization of in-vehicle devices. Remarkable.
