Abstract

PURPOSE:To prevent a receipt from sticking to a cutter and prevent paper jamming from occurring, by fitting an elastic leaf spring to the printer side of the cutter, namely, the lower side of the cutter. CONSTITUTION:A leaf spring 15 is fitted at such a position that the tip thereof is disposed on the lower side of the cutting edge of a cutter 3 so as not to interfere with the cutter 3 at the time of manual cutting of a receipt 15 by the operator, and the tip of the spring 15 is disposed on the front side of the vertical plane of the cutting edge of the cutter 3 so that the receipt 14 makes contact with the tip of the spring 15 before making contact with the cutting edge of the cutter 3. When the operator exerts a tension on the receipt 14 so as to manually cut the receipt 14 by the cutter 3, the spring 15 is energized to the side of the cutter 3, when the receipt 14 is cut. In this case, even if a paper edge of the receipt 14 sticks to the cutting edge of the cutter 3, the paper edge of the receipt 14 is separated from the cutting edge of the cutter 3 by the leaf spring 5.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to POS terminals, EOR, etc., where receipts, which are recording sheets on which product information such as product numbers and prices are printed, are manually pressed. Relating to a cutter device.

2. Description of the Related Art FIGS. 6 and 5 show a cross-sectional view of a receipt cutter in a receipt issuing port of a conventional ECl and a perspective view of an EOR.

In Figure 5, 1 is the housing, 2 is the receipt issuing port for issuing receipts, 3 is the cutter for manually cutting the issued receipts, and 4 is for displaying the product number, price, etc. of the input product. A display section, 5 a keyboard section provided at the front of the housing, and 6 a cash drawer for storing money.

FIG. 6 shows a cross-sectional view of the receipt issuing port 2 shown in FIG. Guide plate that guides up to 2, 3 is printer cover 7
9 is a printer, 1 is attached to a cutter with a saw-shaped tip for cutting the receipt 14;
0 is a platen of the printer 9, 11 is a print head of the printer 9, 12 is a stamp of the hub printer 9, and 13 is a roll paper from which a receipt 14 is made.

Next, the operation will be described. In FIGS. 5 and 6, first, the print head 11 prints on the registration number 4 according to each piece of information input from the keyboard 5. Upon completion of printing, the receipt 14 is sent to the receipt issuing port 2,
An operator manually cuts the issued receipt 14.

Conventionally, the areas that needed to be prevented from paper jams when issuing a receipt were the distance a between the bottom of the cutter 3 and the top of the stamp 12, as shown in FIG. It is constructed so that the purpose can be achieved to some extent by adjusting the distance t from the front part, the angle θ between the receipt 14 sent from the printer 9 and the cutting edge of the cutter 3, etc. in consideration of the ease of cutting the receipt. ing.

Problems to be Solved by the Invention In the above conventional example, it is true that the problem occurs when the toe of the receipt 14 that is manually cut by the operator with the cutter 3 gets into the gap between the bottom of the cutter 3 and the top of the stamp 12. The paper issue had been resolved.

However, the operator manually cuts the receipt 14 with the cutter 3, but at that time,
I'm not sure how to cut the operator's receipt 14.
In rare cases, the tip of the regi stitch 4 gets stuck in the edge of the cutter 3, and the next receipt is sent in that state, causing a paper jam 9 in the receipt issuing port 2.This problem can be solved by: This problem was not solved in the above conventional example.

SUMMARY OF THE INVENTION Therefore, in order to solve the above-mentioned problems, it is an object of the present invention to achieve the effect of preventing paper jams easily and with a simple structure.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention installs an elastic leaf spring on the printer 9 side, which is below the cutter 3, so that the cutter 3 can be cut with a registration mark 4. It has a structure that prevents paper jams by eliminating the sticks.

Operation The present invention has the above-described configuration, so that even if the toe of the receipt 140 bites into the cutting edge of the cutter 3 when the operator manually cuts the receipt 14 with the cutter 3, the elastic force of the leaf spring prevents the cutter 3 from cutting. and the receipt 14 can be separated. Therefore, paper jams can be prevented, and the conventional maintenance associated with paper jams can be eliminated by the present invention.

Example FIG. 1 shows an embodiment of the present invention.

In Figure 1, 3 is a cutter, 7 is a printer cover,
14 is a receipt, and 15 is a leaf spring. The mounting position of the leaf spring 15 is such that the leaf spring 15 is vertically lowered than the cutting edge of the cutter 3 so that it does not get in the way of the cutter 3 when the operator manually cuts the receipt 15. In order to have a structure in which the blade of the leaf spring 15 comes into contact with the blade of the cutter 3 before the blade edge of the cutter 3, the blade of the leaf spring 15 is set to be located in front of the vertical plane of the blade edge of the cutter 3.

In addition, the leaf spring 15 is flexible enough to be easily bent by the applied tension, and the leaf spring 15 is flexible enough to be easily bent by the applied tension, and the tension applied to the receipt 14 by the operator is such that it can be easily bent. The spring material has such characteristics as to have elasticity that easily returns to its original state when the tension is removed.

Now, the operator cuts the receipt 14 manually with the cutter 3 from the state shown in FIG.
When tension is applied to the plate spring 15, the plate spring 15 is urged toward the cutter 3 (see FIG. 2) due to the above-mentioned mounting position and material of the plate spring 15 (see FIG. 2), at which point the receipt 14 is cut. At this time, even if the tip of the receipt 14 were to get caught by the cutting edge of the cutter 3, the installation of the leaf spring 15 would be dependent on the location and material.

From this relationship, as shown in FIG. 3, the leaf spring 15 separates the toe of the reggae stitch 4 that is bitten from the cutting edge of the cutter 3.

Further, FIG. 4 shows another embodiment, where 7 is a printer cover, and 3 is a cutter made of a material with elasticity that is strong enough to be bent by the tension applied to the registration stitches 4, which is attached to the printer cover 7. .

14 is a receipt, and 16 is a stopper for holding the cutter 3 at an angle.

To explain the operation, in the initial state, when the operator applies tension to the receipt 14 in an attempt to cant the receipt 14, the tension is transmitted to the cutter 3, causing the cutter 3 to tilt. It stops at this position and the receipt 14 is cut at this point. At this time, even if the tip of the receipt 14 is bitten by the cutting edge of the cutter 3, the tension applied to the receipt 14 is after the receipt 14 is canted, so it becomes "0" and the cutter 3 returns to its original state. . Due to the elastic force at that time,
The tip of the receipt 14 that has been bitten is separated from the cutting edge of the cutter 3.

Effects of the Invention As is clear from the above embodiments, the present invention has a structure in which the elastic force of a leaf spring is used to separate the tip of the receipt that has been bitten by the cutter, so the advantage is that paper jams can be prevented with a simple structure. has.

Moreover, since the gap between the cutter and the guide can be made smaller, it is possible to prevent coins and the like from falling into the printer through the gap between the cutter and the guide.
