Abstract

PURPOSE:To realize easy and smooth cutting by providing a damper for securing a roll paper to be cut. CONSTITUTION:A printed roll paper 20a is introduced on a paper feed roller 22 into a cutter 25 mounted above a printer 21. A second drive source operates to push the roll paper 20a against a guide board 33 by means of a fixed damper 27. At the same time, a first drive source operates to slide a movable cutter 29 interlocked through an interlocking lever 31 on a fixed cutter 28 thus cutting the paper. Upon finish of cutting, the second drive source 34 is released and a fixed damper 32 is reset by means of a spring 35.

Description

[Detailed Description of the Invention] Industrial Field of Use The present invention is applicable to printers and the like that have the function of printing various types of information such as issuing receipts and printing the type of food in the kitchen, etc., and cutting the information at the required position. Concerning the available cutter devices.

BACKGROUND OF THE INVENTION Conventionally, this type of cutter device has a cutter that cuts printed paper and a drive unit that drives the cutter, and when the cutter operates, the paper to be cut is not held (fixed). It is configured to be canted. FIG. 3 shows a conventional cutter device.

In FIG. 3, 1 is a roll paper that is a medium for printing various information, 2 is a printer that prints various information, 3 is a paper feed roller for feeding the roll paper 1, and 4 is a roll paper 1
5 is a printing head for printing information on the roll paper 1 using the printing gutter 4, a platen serves as a receiver for printing, and 6 is a counter for cutting the printed paper at a predetermined position. The unit 7 is an entrance portion for guiding the paper 1 printed from the printer 2 to the cutter unit 7;
9 is a fixed blade of the cutter, and 9 is a movable blade of the cutter.
10 is a drive source for operating the movable blade 9; the movable blade 9 and the drive flXO are connected by a connecting plate 11; 12
．． Reference numeral 13 denotes a guide plate for guiding the roll paper l to the outlet section 14.

Next, the operation will be explained based on FIGS. 3 and 4.

FIG. 3 shows a roll paper 1 inserted into a printer 2 by a feed roller 3, various necessary information printed by a print head 4, and a cutter unit located at the top of the printer 2. This shows the state sent to step 6, which is the stage before the state to be cut.

FIG. 4 is a diagram showing the state in which the roll paper 1 is pressed and grated. From the state shown in FIG. 1, the movable blade 9 operates to remove the roll paper 1.
When the paper is cut, the print head 4 operates according to the print signal, and when printing is completed, the roll paper 1 is sent to a predetermined cutting position by the feed roller 3 based on the feed signal.

Once at a predetermined position, the drive source 10 is activated by a cutting signal, the movable blade 9 is activated via the connecting plate 11, and the roll paper 1 is
cut. The movable blade 9 and the fixed blade 8 cut the roll paper between the movable blade 9 and the fixed blade 8 so that both blades touch each other.9 FIG. 5 shows an example of the shape of the blade of the movable blade 9. It is something.

A groove 15 is provided in a part of the movable blade 9, so that even when it is cut, a part of it is connected to the roll paper 1 inside the printer 2, and as shown in Fig. 2, even if it is cut, the cut roll paper I made sure that 1a did not fall down, and the operator pulled it out to cut it.

Problems to be Solved by the Invention However, in the above conventional cutter device, the movable blade 9
When the machine operates, the roll paper 1a to be cut is free, so when cutting, the roll paper 1a moves, making it difficult to cut, or the operator may forcefully pull the paper 1a during cutting, putting an abnormal load on the movable blade 9, causing it to become movable. Damage the blade of blade 9,
I had a problem with bending it. Further, if the printer moves to the next operation in the above-mentioned state, paper jams may occur, which may cause trouble in the printing gutter 4 and other problems.

The present invention solves the above-mentioned conventional problems, and uses an excellent counter device that completely fixes the roll paper 1a when cutting the roll paper 1a and takes measures against abnormal processing from the outside. The purpose is to provide

Means for Solving the Problems In order to achieve the above object, the present invention provides a fixing damper that fixes the roll paper to be cut before the movable blade operates, so that the operator can avoid cutting during printing. Even if the roll paper is pulled up, it does not affect the cutting operation in any way.

Another purpose is that even if a foreign object gets mixed in (falls) during the cutting operation, the fixed damper acts as a step to prevent it from falling, thereby preventing both the fixed blade and the movable blade from colliding.

Effects The present invention has the following effects due to the above-described structure. In other words, when cutting roll paper, the operator must hold down the roll paper to be cut, then activate the movable blade, and the machine will not move even if the operator tries to pull up the roll paper during cutting, and the cutting process will be completed smoothly. I can do it.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, 20 is a roll paper that is a medium for printing various information, 21 is a printer that prints various information on the roll paper 20, 22 is a paper feed roller for feeding the roll paper 20, and 23 is a roll paper 20 A print head 24 is a platen that serves as a receiver for printing when information is printed on the roll paper 20 by the printing gutter 23. , 25
A cutter unit 26 is located at the top of the printer 21 and is used to cut the printed paper at a predetermined position.
The roll paper 20 printed by the printer 21 is
27 is an inlet section for leading to the terminal unit 25 and an outlet section.

28 is the fixed blade of the cutter, 29 is the movable blade of the cutter,
Reference numeral 30 denotes a first drive source for operating the movable blade 29, and the movable blade 29 and the first drive source 30 are connected by a connecting lever 31.

32 is a fixing damper that presses against the guide plate 33 via the roll paper 20a to fix the roll paper 20a to be printed and cut; 34 is a second drive source for driving the fixing damper 32; 35 is a fixing damper This is a spring that acts when the damper 32 is released.

FIG. 2 is a diagram showing a state in which the fixing damper 32 is activated.

First, roll paper 20 is fed into printer 21 .

The roll paper 20 is fed by a paper feed roller 22, and various information is printed by a gutter 23. The printed roll paper 20a is transferred to the printer 21 by the paper feed roller 22.
It is guided into a canter device 25 installed in the upper part of the canter.

First, the second drive source moves to fix the guided roll paper 20a, and following this, the roll paper 20a is pressed against the guide plate 33 by the fixing damper 27. At the same time, the first drive source operates, and the movable blade 29 connected by the connecting lever 31 slides and comes into contact with the fixed blade 28 to cut the paper. Once the cutting is complete, the second
The drive source 34 is released, and the spring 35 returns the fixing damper 32 to its original position.

As a result, the roll paper 20a to be cut is fixed by the fixing damper 32, so even if the operator tries to pull it up during cutting, the roll paper 20a will not move.
Allows for smooth cutting. Further, the fixing lever is released at the same time as the cutting is completed, allowing normal work to be carried out.

Effects of the Invention As is clear from the above embodiments, the present invention has the following effects.

(1) When cutting roll paper, the roll paper is fixed, so the roll paper becomes stiffer and easier to cut.

(2) Since the roll paper is fixed during cutting, it will not move even if the operator pulls it up in the middle of cutting.
A smooth cutting process can be achieved.

(3) The effect of (2) eliminates paper jams and improves reliability of the printer.

(4) When cutting, the fixed damper blocks the outlet, so
Prevents foreign objects from falling. It also helps protect the canter.
