DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium issuing device for issuing tickets such as air tickets, and more particularly to a tension applying mechanism capable of applying tension to a continuous medium.

2. Description of the Related Art Recently, automatic issuing machines for automatically issuing tickets such as air tickets and traveler checks have been developed and put into practical use. In such an apparatus, a continuous medium provided with a perforation at a cutting position is usually used. Although it is issued by cutting with a cutter, the medium may loosen at the cutting position due to the difference in transport speed of the rollers that transport the medium, and cutting may not be performed normally, so a method that can be cut normally with a simple mechanism Is desired.

[0003]

2. Description of the Related Art FIG. 8 is a perspective view of an air ticket issuing apparatus.
As shown in the figure, a paper storage box 2 containing a continuous paper 1a provided with a perforation 10 and a magnetic recording area on the back surface, and feed rollers 3a, 4a, R1 arranged at a predetermined interval.

As shown in FIG. 9, a feed roller 3a, 4a has a belt B1 hung on pulleys P1, P2 attached to the ends of respective shafts 30, 40 and a pulley P3 on the shaft of a motor M, and a motor M
, And rotate in the same direction in conjunction with the drive. Further, the feed rollers R1 to R3 shown in FIG. 8 are driven by a drive source (not shown) separate from the feed rollers 3a and 4a. Therefore, the continuous paper 1a supplied from the paper storage box 2 is fed by the feed roller 3a and the pressing roller.
Conveyed by 5a, feed roller 4a and press roller 6a,
It stops at a predetermined position, and is cut from the perforation 10 by the cutter 70 of the cutter unit 7 to form the sheet 1A.

On the paper 1A, predetermined data (for example, destination, departure / arrival time, boarding machine number, seat number, etc.) is magnetically recorded by the R / W 8, a recording check is performed, and feed rollers R1 to R3 and press rollers R4 to R6. The printer 9 prints the data and sends it out in the direction of the arrow to be issued as a ticket.

[0006]

According to the above conventional method, the continuous paper 1a is stopped between the feed rollers 3a and 4a arranged at intervals and cut by the cutter 7.
At this time, there is a difference in the transport speed due to the outer diameter accuracy of the feed rollers 3a and 4a for transporting the continuous paper 1a, and the cutting may not be performed normally because the continuous paper 1a is loosened at the cutting position. However, there is a problem in that ticket issuance is hindered.

An object of the present invention is to provide a tension applying mechanism that can normally cut continuous paper.

FIG. 1 is a diagram illustrating the principle of the present invention. In the drawing, reference numerals 3 and 4 denote a first feed roller and a second feed roller arranged at predetermined intervals, and 5 and 6 denote first and second feed rollers which are in rolling contact with the first feed roller 3 and the second feed roller 4, respectively. A first pressing roller and a second pressing roller 11 are driving means for rotating the first feed roller 3 and the second feed roller 4 which can be driven in forward and reverse directions.

Therefore, when the driving means 11 is driven in the forward direction,
When the medium 1 is nipped and conveyed by the first feed roller 3 and the first press roller 5, the second feed roller 4 and the second press roller 6, and the driving means 11 is driven in the reverse direction, the first
The first feed roller 3 and the second feed roller 4 are configured to rotate in a direction for transporting the medium 1 in a direction opposite to the interval.

[0010]

The medium 1 is nipped and conveyed by the first feed roller 3 and the first pressing roller 5 and the second feed roller 4 and the second pressing roller 6 by the forward drive of the driving means 11. Next, when the driving unit 11 is driven in the reverse direction, the first feed roller 3 and the second feed roller 4 rotate in the direction of transporting the medium 1 in the opposite direction to the interval, so that the first feed roller 3 and the The medium 1 held between the first pressing roller 5, the second feed roller 4 and the second pressing roller 6 is pulled back and forth, and is conveyed by the first feed roller 3 and the second feed roller 4. The slack due to the speed difference is eliminated and tension is applied.

Therefore, the medium 1 can be normally cut by, for example, cutters arranged at intervals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment (corresponding to claims 1, 3 and 5) in which the present invention is applied to the air ticket issuing apparatus described in the conventional example will be described with reference to FIGS. explain. The same reference numerals indicate the same objects throughout the drawings. The motor M in FIG. 2 corresponds to the driving means 11 in FIG.

The embodiment of FIG. 2 differs from the conventional example described with reference to FIG. 8 in that a tension applying mechanism 12 including a feed roller 4A is provided instead of the feed roller 4a. That is, as shown in FIG. 2, the tension applying mechanism 12 is constituted by the feed rollers 3a and 4A, the pressing rollers 5a and 6a, and the gear group.

As shown in the perspective view and the side view of FIGS. 3A and 3B, a gear G1 is fixed coaxially to the shaft 40 of the feed roller 4A, and the gear G2 meshes with the gear G1. Gears G3, G4 of the same diameter mounted on the drive shaft 31 of the drive shaft 31 via the one-way clutches C1, C2 respectively mesh with G2. A pulley P4 is attached to one end of the drive shaft 31, and pulleys P1, P3, P4
The belt B2 is hung on.

The one-way clutches C1 and C2 are mounted so as to rotate the gears G3 and G4 in one direction in opposite directions. That is, when the pulley P4 rotates in the direction of arrow A,
The one-way clutch C1 is disengaged, the gear G3 idles, the one-way clutch C2 operates to rotate the gear G4, rotate the gear G1 via the gear 2, and rotate the feed roller 4A in the feed direction of the continuous paper 1a.

When the pulley P4 rotates in the direction of arrow B, the one-way clutch C2 is disengaged, the gear G4 idles, and the one-way clutch C1 operates to rotate the gear G3 to rotate the gear G1.
And the feed roller 4A is similarly rotated in the feed direction of the continuous paper 1a.

With such a configuration, the continuous paper 1a supplied from the paper storage box 2 is rotated in the forward direction of the motor M, that is, in the direction of arrow C in FIG.
Direction, and as shown in FIG. 4 (a), the feed rollers 3a, 4
A rotates in the same direction and is transported in the feed direction.

When the continuous paper 1a is conveyed to a predetermined position, the motor M stops and further rotates in the opposite direction, that is, in the direction of arrow D in the figure. Then, the pulleys P2 and P4 rotate in the direction of arrow B, and as shown in FIG. 4B, the feed roller 3a rotates in the reverse direction, and the feed roller 4A rotates in the forward direction.

Therefore, the continuous paper 1a is pulled so that the feed roller 3a and the feed roller 4A rotate so that they are conveyed in opposite directions to each other, regardless of whether or not there is a slack. Then, the continuous paper 1a is cut from the perforations 10 by the cutter 70 of the cutter unit 7 to become the paper 1A.

The paper 1A is conveyed by driving the feed rollers R1 and R2, and magnetic data and print data are recorded by the R / W unit 8 and the printer unit 9 and are issued as tickets. 5 to 7 show different embodiments (corresponding to claims 2, 4 and 5).

FIG. 5 differs from the embodiment described in FIG. 2 in that when the motor M is driven in the reverse direction, the feed roller 3a is stopped instead of rotating in the reverse direction. In the example, the moment the continuous paper 1a is cut while the feed roller 3a is rotating in the reverse direction, the remaining one of the continuous paper 1a is returned in the reverse direction, thereby preventing this.

That is, as shown in FIG. 5, a pulley P1 is attached to one end of the shaft 30 of the feed roller 3A via a one-way clutch C3. That is, when the motor M is driven in the forward direction, the one-way clutch C3 operates and the feed roller 3A rotates in the forward direction. When the motor M is driven in the reverse direction, the one-way clutch C3 is disengaged and the pulley P1 runs idle. Feed roller
3A does not rotate.

Therefore, when the motor M is driven in the reverse direction,
As shown in FIG. 6, the feed roller 4A rotates in the feed direction,
Since the feed roller 3A does not rotate with the rotational force of the pulley P1,
As the slack of the continuous paper 1a is temporarily pulled and tension is applied, and thereafter the paper is fed by the feed roller 4A with the tension, as shown in the time chart of FIG. The cutter 70 cuts from the perforation 10 at the timing when the slack is pulled by the feed roller 3A.

Then, since the feed roller 3A does not rotate, the cut continuous paper 1a can be prevented from being sent in the reverse direction, and the transport distance to the next cutting position can be shortened. Therefore, although the time reduction for each ticket is slight, the issuance time is shortened when a large number of tickets are issued continuously.

In this manner, the mechanism for applying tension to the continuous paper 1a and the simple mechanism sharing the feed roller for transporting the continuous paper 1a can normally cut the continuous paper 1a without cost. An application mechanism is obtained.

In the above example, the air ticket issuing apparatus for cutting the continuous paper 1a has been described. However, it is needless to say that the present invention can be similarly applied to the case where the continuous paper 1a is cut by another apparatus.
The present invention is not limited to the case where the continuous paper 1a is cut, and can be applied to a case where a stamp or printing is performed on a medium to which tension is applied.

Although the case of the continuous paper 1a has been described, the present invention can be similarly applied to the case of a cut sheet.

[0028]

As described above, according to the present invention, in the first and third aspects, when the driving means is driven in the forward direction, the first feed roller, the first pressing roller, and the second When the medium is nipped and conveyed by the feed roller and the second pressing roller and the driving unit is driven in the reverse direction, the first feed roller and the second feed roller transfer the medium in directions opposite to each other with respect to the interval. By being configured to rotate in the transport direction, tension can be applied to the medium between the first feed roller and the second feed roller, and the medium is cut within an interval, for example, as in claim 5. In this case, even if the medium is slackened by the feed speeds of the first feed roller and the second feed roller, the medium can be properly tensioned and cut.

According to the second and fourth aspects, when the drive means is driven in the reverse direction, one of the feed rollers is stopped to apply tension to the medium, and
For example, when the medium is cut within the interval, the remaining medium can be prevented from retreating, the transport distance to the next cutting position is shortened, and the medium is cut many times. In that case the overall time is reduced. This has the effect.
