Description

[Detailed explanation of the invention] This invention is based on paper sheets that are cut between a fixed blade and a movable blade.
For example, the present invention relates to a cutter device for a ticket issuing machine that prevents a ticket from being drawn in the cutting direction of a movable blade.

Generally, a cutter device for a ticket issuing machine is configured to cut long paper sheets between a fixed blade and a movable blade.

However, in the cutter device of the conventional ticket issuing machine, the cut ticket is attracted to the movable blade by the static electricity generated when cutting the paper sheet, for example, the ticket paper 3, and the cut ticket is cut by the movable blade. In some cases, the device may be pulled in the direction of the object, making it difficult to take it out.

In particular, when the cut portion is covered with a cutter cover or the like, it becomes even more difficult to take out the cut ticket 3a.

Furthermore, in this case, if the winding diameter of the rolled ticket paper loaded in the ticket issuing machine becomes small, the ticket paper will not be fed in the correct direction due to the curling of the ticket paper, and the cutter cover will The problem has been that the ticket gets stuck between the ticket and the fixed blade, making it impossible to cut the ticket, or even if it can be cut, the cut ticket cannot be taken out.

This idea was made in consideration of the above-mentioned circumstances, and when cutting is performed between the fixed blade and the movable blade, the uncut or cut paper sheets are pulled in the cutting direction of the movable blade. To provide a cutter device for a ticket issuing machine which can prevent paper sheets from being cut and easily take out cut paper sheets to the outside.

An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

Figure 1 shows the relationship between the printing section and the cutter device in the ticket issuing machine. Paper sheets, such as ticket paper 3, which are sent out in the direction of the arrow in the figure from the bottom by platen 1 and pinch roller 2, are printed. After a predetermined print is made in a print unit consisting of a head 4 and a platen 1, the print is sent to a cutter device 5, which is the main part of this invention.

The ticket paper 3 is in the form of a roll, and is loaded into a predetermined loading section within the ticket issuing machine.

In the cutter device 5 shown in FIG. 1, 6 is a fixed blade;
is a movable blade.

The fixed blade 6 is integrally fixed on the frame 8 together with one end of a cutter cover 9 as a fixed part.

The side surface of the frame 8 serves as a guide surface for the ticket paper 3, and the paper guide 1 is placed opposite the guide surface of the fixing member 8.
0 is set.

Further, one end of a plate-shaped elastic piece 11 made of, for example, rubber is fixed to the other end of the cutter cover 9 with an adhesive.

The elastic piece 11 has its other end opposed to the fixed blade 6 so that the distance A between the elastic piece 11 and the fixed blade 6 is slightly narrower than the thickness of the movable blade 7.

On the other hand, the movable blade 7 is moved to the first position by a drive mechanism (not shown).
It is movable in the left and right directions in the figure.

Therefore, when the movable blade 7 is moved in the cutting operation direction, that is, in the left direction in the figure, the movable blade 7 enters between the fixed blade 6 and the other end of the elastic piece 11, and the elastic piece 1
The ticket paper 3 is cut while contacting the other end of the ticket paper 3.

In the figure, 12 is a cutter cover of the movable blade 6, and 3a is a ticket cut from the ticket paper 3.

FIGS. 2a to 2c show the specific structure of the cutter device 5. As shown in FIG.

That is, the movable blade 7 is rotatable about the shaft 13 and is always urged toward the stopper 15 by the spring 14.

The movable blade 7 has a long hole 20 in the middle part, and this long hole 2
A pin 19 attached to the tip of the cutter support member 16 is inserted into the cutter support member 16, and when the support member 16 rotates around the shaft 18, the movable blade 7 rotates around the shaft 13.
The cutting operation of the ticket paper 3 is performed.

Further, a switching member 21 is supported on the shaft 18 so as to be slidable in the left-right direction in FIG.
6 and the switching member 21 are designed to rotate together with the shaft 18 as a fulcrum.

In the figure, 17 is a drive arm that presses and rotates the switching member 21, and the switching member 21 has two step portions 21a and 21b at the part where the drive arm 17 comes into contact.
By sliding the switching member 21 and adjusting the drive arm 17 to press either step 21a or 21b, the amount of rotation of the switching member 21, that is, the amount of rotation of the movable blade 7, is adjusted, as shown in FIG. like ticket paper 3
When completely cutting the ticket paper 3 as shown in Figure 2C,
It is now possible to select between so-called incomplete cutting, in which a portion of the material is left uncut.

Next, the operation of this device will be explained.

First, when the movable blade 7 is in the rest position shown in FIGS. 1 and 2a, the ticket paper 3 is delivered to a predetermined setting position.

Next, when a predetermined cutting operation is performed, the drive arm 17 presses one step 21a of the switching member 21 as shown in FIG. The ticket paper 3 is cut while entering between the elastic piece 11 and the other end.

At this time, since the other end of the elastic piece 11 is in contact with the outer surface of the movable blade 7, the static electricity generated during this cutting operation
The ticket 3a cut between the fixed blade 6 and the movable blade 7 is attracted to the movable blade 7, and even if it tries to be pulled in the direction of the cutting operation of the movable blade 7, it is not pulled in by the elastic piece 11 as shown in FIG. being prevented from being

Then, as shown in FIG. 4, when the movable blade 7 returns to the rest position, the elastic piece 11 also returns in the same direction, and the cut ticket 3a is repelled in the removal direction.

Note that when the switching member 21 is slid to the right as shown in FIG. It is possible to perform so-called incomplete cutting, in which the portion (left side in the figure) is left uncut.

Thus, in this device having the above-described configuration, after cutting the ticket paper 3, even if the ticket 3a is attracted to the outer surface of the movable blade 7 due to static electricity generated during cutting, the movable blade 7 moves in the direction of the cutting operation. At this time, since the elastic piece 11 is in contact with the outer surface of the movable blade 7, the cut ticket 3a is reliably prevented from being drawn in the direction of the cutting operation of the movable blade 7 by the elastic piece 11, and the ticket 3a is cut. The ticket 3a can be easily taken out.

In addition, even if the roll diameter of the ticket paper 3 is shortened and the ticket paper 3 is curled, the other end of the elastic piece 11 is close to the fixed blade 6, so when feeding the paper,
The ticket paper 3 is attached to the cutter cover 9 by the elastic piece 11.
This can prevent the blade from getting between the blade and the fixed blade.

Note that this invention is not limited to the embodiments described above.

For example, in the above-described embodiment, one end of the elastic piece 11 is fixed to the cutter cover 9 as a fixed part with adhesive, but as shown in FIG. An attachment hole 32 may be provided, and a locking portion protruding from one end of the elastic piece 34 may be fitted and fixed into the attachment hole 32.

Further, the other end of the elastic piece may be brought into contact with the fixed blade 6.

In this case, it is possible to more reliably prevent the ticket paper 3 from entering between the cutter cover 9 and the fixed blade 6 during paper feeding.

As explained above, according to this invention, when cutting is performed between the fixed blade and the movable blade, the uncut or cut paper sheets are prevented from being drawn in the direction of the cutting operation of the movable blade. It is possible to provide a cutter device for a ticket issuing machine that can prevent the above problems and easily take out cut paper sheets to the outside.

In particular, since the tip of the elastic piece is located closer to the cutting operation direction of the movable blade than the tip of the fixed blade, feeding and feeding of paper sheets is not prevented, and the distance between the tip of the elastic piece and the fixed blade is Since the thickness of the movable blade is smaller than the thickness of the movable blade, there is no gap between the movable blade and the elastic piece, which further prevents the cut paper from being pulled in the direction of the movable blade's cutting operation. It can be made certain.
