Abstract

PURPOSE:To realize smooth cutting by interlocking a damper for securing a roll paper to be cut with a cutter. CONSTITUTION:In order to cut a roll paper 20a introduced into a cutter unit 25, a drive source 30 operates to move a movable cutter 29 through an interlocked lever 31. The movable cutter 29 is coupled directly with a fixing damper 32 and when the movable cutter 29 moves, the roll paper 20a is secured and cut. Since the movable cutter and the fixed damper are integrated, the roll paper is cut reliably without causing a malfunction where the roll paper is cut without operating the fixed damper.

Description

[Detailed Description of the Invention] Industrial Fields of Application The present invention is applicable to receipt issuing, kitchens, etc.
! The present invention relates to a cutter device that can be used in printers, etc., which has the function of printing various information such as printing information, and cutting it at a necessary position.

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 have a force of 7. FIG. 4 shows a conventional cutter device.

In FIG. 4, 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 I
5 is a platen that receives the print when information is printed on the roll paper 1 by the print head 4; 6 is a cutter unit for cutting the printed paper at a predetermined position; Reference numeral 7 denotes an inlet portion for guiding the printed paper l from the printer 2 to the canter unit 7, 8 a fixed blade of the cutter, and 9 a movable blade of the cutter. 10
is a drive source for operating the movable blade 9, and the movable blade 9 and the drive source 10 are connected by a connecting plate 11, 12.13
is a guide plate for guiding the roll paper 1 to the exit section 14.

Next, the operation will be explained based on FIGS. 4 and 5.

FIG. 4 shows that a roll paper 1 is inserted into a printer 2 by a feed roller 3, various necessary information is printed by a print head 4, and the printed roll paper 1 is transferred to a cutter unit located at the top of the printer 2. .

This shows the state in which it has been sent to Toro, which is the stage before it should be cut.

FIG. 5 is a diagram showing a state in which the roll paper 1 is cut. From the state shown in Fig. 1, the movable blade 9 operates and the roll paper 1 is cut.As for the flow of signals, the print head 4 is operated by the print signal, and when printing is completed, the feed roller 3 is moved by the feed signal. The roll paper 1 is fed to a predetermined cutting position.

When the predetermined position is reached, the drive source 1° is activated by the cutting signal, and the movable blade 9 is activated via the connecting plate 11 to cut the roll paper.
cut. The movable blade 9 and the fixed blade 8 cut the roll paper 1 between the movable blade 9 and the fixed blade 8 so that both blades are in contact with each other.

FIG. 6 shows an example of the shape of the movable blade 9.

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 1a
The operator was able to pull it out and cut it out so that it would not fall down.

Problems to be Solved by the Invention However, in the above-mentioned conventional force-cutting 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, problems such as paper jams may occur and the print head 4 may be damaged.

The present invention solves the above-mentioned drawbacks of the conventional technology, and provides an excellent cutter 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

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.

Furthermore, even if foreign matter gets mixed in (falls) during the cutting operation, the fixed damper serves to prevent it from falling, and another purpose is to prevent both the fixed blade and the movable blade from colliding.

Effects The present invention has the following effects due to the above structure. In other words, when cutting roll paper, the operator must hold down the roll paper to be cut, then operate the movable blade, and even if the operator tries to pull up the roll paper in the middle of cutting, it does not move and the cutting process is completed smoothly. I can do it.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 6, 20 is a roll paper which is a medium for printing various information, and 21 is a roll paper 20 for printing various information. A printer, 22 is a paper feed roller for feeding the roll paper 20, 23 is a print head 24 for printing on the roll paper 20, and when printing information on the roll paper 20 by the printer 23, the print receiver is on the part. It is a platen. Reference numeral 25 is a cutter unit located at the upper part of the printer 21 for cutting the printed paper at a predetermined position. Reference numeral 26 is an entrance for guiding the printed roll paper 20 from the printer 21 to the cutter unit 25. Section 27 is an outlet section.

28 is the fixed blade of the cutter, 29 is the movable blade of the cuckoo,
30 is a drive source for operating the movable blade 29;
9 and the drive source 30 are connected by a connecting lever 31.

32 is a fixing damper 1 that presses the roll paper 20a against a guide Fi 33 for fixing the roll paper 20a to be printed and cut, and the fixing damper 32 is held by a fixing holding fitting 36 fixed to the movable blade 29. is,
The structure is such that driving is performed by a spring 35.

FIG. 2 is a diagram showing the positional relationship between the fixed damper 32 and the movable blade 29.

The tip position of the fixed damper 32 must be shifted by a dimension A from the tip position of the movable blade 29. This is so constructed that when the movable blade 29 operates, the fixing damper 32 hits the roll paper 20a first, fixing the paper, and then cutting the paper with the movable blade 29 and the fixed blade 28.

FIG. 3 is a diagram showing a state in which the movable blade 29 is in operation. 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 printing hand 23.

The printed roll paper 20a is guided by a paper feed roller 22 to a cutter device 25 installed at the top of the printer 21. In order to cut the guided roll paper 20a, the movable blade 29 is moved via the connection lever 31 by the operation of the drive source 30. As explained in FIG. 5, this movable blade 29 is directly connected to the fixing damper 32, and by moving the movable blade 29, the roll paper 20a can also be fixed and cut.

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 printer reliability.

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

(5) Since the movable blade and the fixed damper are integrated, cutting can be performed without the fixed damper operating. This allows for reliable cutting without making any mistakes.

(6) Only one driving source is required, making it economical.
