The power supply unit 6 and the like for supplying power to the above-described units are provided. The card receipt handling section 2 is provided with a paper supply device 7 as shown in FIG.

As shown in FIG. 1, the paper supply device 7 includes a main body hopper 9 for accommodating a roll-shaped receipt paper 8, and performs processing when the roll-shaped receipt paper of the main body hopper is consumed. It has a spare hopper 10 for accommodating the roll-shaped receipt paper 8 for supplying a spare roll-shaped receipt paper 8 'so that it can be continued.

A transfer belt 11 on which the roll-shaped receipt paper 8 is placed and sent out on the main body hopper 9 and a rear portion of the roll-shaped receipt paper 8 are covered so as to prevent the paper from coming out when setting the receipt paper. Covers 13 and 1 that are opened when replenishing spare roll receipt paper
3 'and the receipt paper 8 from the roll receipt paper 8
a and a sensor 15 for detecting the end of the receipt paper.
0 is provided with a stopper 16 and a push-up lever 17 operated by a solenoid (not shown).

The covers 13 and 13 'are supported by hinge pins 12 and 12', respectively, and are connected by connecting rods (not shown) so that the right and left covers can be interlocked, and can be opened and closed right and left by solenoids (not shown). ing. The structure of the covers 13 and 13 'may be such that the shutter slides up and down or left and right. In this conventional example, it is simpler to swing right and left with a hinge pin to open and close, and the opening and closing angle of the left and right covers is increased. Also, since it is small and can be configured to be small, it is of the left-right opening and closing type using hinge pins.

When the receipt paper 8 of the main body hopper 9 is consumed during the depositing and withdrawing processing, and the sensor 15 detects the end of the receipt paper 8, the covers 13 and 13 'are opened in the main body hopper 9 and at the same time, not shown in the spare hopper 10. The solenoid is energized to operate, and lowers the stopper 16 and pushes up the push-up lever 17. Thereby, the spare hopper 10
The pre-rolled receipt paper 8 ′ inside falls on the conveyor belt 11 of the main body side hopper 9.

Thereafter, the cover 13 and the
13 'is closed, the roll-shaped receipt paper 8 is rotated backward by one or more times by the conveyor belt 11 to remove the slack, and then the receipt paper 8a is rotated forward to form a roll-shaped receipt paper 8a. The leading end is separated by a separator 14 and sent to the printing section of the card receipt handling section.

[0008]

In such a conventional paper feeding apparatus, the covers 13 and 13 'are of an openable type in which the covers which are opened for replenishing the pre-rolled receipt paper swing about the hinge pins. For the cover 13, 1
If the lower end of 3 'is long, it interferes with the conveyor belt when the lower end is opened, and the swing angle of opening and closing the covers 13 and 13' cannot be made large to reduce the size of the apparatus. Because the lower end of 13 'interferes
As shown in FIG. 7, the covers 13 and 13 'are shortened to provide a gap from the lower end to the conveyor belt 11. Therefore, there is a space between the lower ends of the covers 13 and 13 'and between the conveyor belts so that the receipt paper cannot be guided. For this reason, there is a problem in that the leading edge of the receipt paper 8a jumps out of the space when the paper is set, and a jam occurs.

The separator 14 has a width R which is substantially the same as the receipt paper and has a radius equal to the plate thickness by folding back as shown in FIG. 8 (b) so as not to damage the receipt paper. As shown in FIG. 8A, if there is a turn 8b or an uncut portion 8c at the end of the receipt paper 8a as shown in FIG. 8A, the leading end of the paper 8a becomes a roll-shaped portion of the receipt paper, the separator 14 and the like as shown in FIG. In some cases, the leading end of the receipt paper from the roll-shaped portion of the receipt paper cannot be properly separated. In particular, separation cannot be performed when the leading edge of the paper is attached to the roll-shaped portion due to static electricity.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention prevents the leading edge of the receipt paper from jumping out of the cover when the paper is set, prevents jamming, and ensures the separation of the leading edge of the paper. Try to realize the device.

1 to 3 are views showing an embodiment of a paper feeding apparatus according to the present invention. FIG.
FIG. 2 is a view as viewed in the direction of the arrow Z in FIG. 1, and FIG. 3 is a view showing a separator. In the present embodiment, as shown in FIG.
The main hopper 20 includes a conveyor belt 23 that supports the roll-shaped receipt paper 22 stored in the hopper, and a pair of cover belts that cover the rear part of the roll-shaped receipt paper 22 on the conveyor belt 23. Covers 24, 24 '
And the receipt paper 22a from the roll receipt paper 22
Separator 25 to separate its tip to draw out
And a sensor 26 for detecting the end of the receipt paper 22a pulled out of the roll receipt paper 22.

The spare hopper 21 holds the spare receipt paper 2
2 ′, 22 ″, and the spare receipt paper 22 ′, 2 ″
Lever 27, 27 'for sending 2 "to main body side hopper 20
A solenoid 28 for driving the levers 27, 27 ';
28 '. Reference numeral 29 denotes a printing unit of the card receipt handling unit.

The rear shaft 30 'of the two shafts 30 and 30' for supporting the belt of the conveyor belt 23 is provided with impellers 31 and 31 'having a plurality of blades radially. The impellers 31, 31 'are made of a soft material having elasticity such as rubber or (for example, urethane rubber).
The impeller shown in FIG. 1 is not only formed in a radial shape with respect to the rotating shaft but also formed in a brush shape with a soft material such as nylon and provided in a radial shape on the rotating shaft. The same function as that of 31, 31 'can be performed.
Further, the tip of the impeller 31, 31 'is
The length of the mounting paper 3 is such that it does not come into contact with the roll receipt paper 22 above, and the mounting width is such that the outside of the impellers 31 and 31 ′ is substantially the same as the outside of the roll receipt paper 22 as shown in FIG. It is attached to become.
As a result, the leading end of the receipt paper is covered by the covers 24, 24 '.
Even if it tries to jump out from the lower end of the conveyor belt, the tip ends thereof can be guided in the conveyance direction of the conveyance belt by the impellers 31 and 31 'rotating in the conveyance direction of the conveyance belt.

The separator 25 has a leading end slightly separated from the contact point between the roll-shaped receipt paper 22 and the conveyor belt 23 in the traveling direction of the conveyor belt 23 and the receipt paper 2.
It is provided at a position where the tip of 2a can be separated. The roll receipt paper 22 is conveyed in the direction of the printing unit 29 by the conveyance force of the conveyance belt 23 from the gap between the leading end of the separator 25 and the conveyance belt 23. The shape of the separator 25 is as shown in FIGS. 3 (b) and 4 (c).
A hinge portion 25a arranged in a tangential direction of the roll-shaped receipt paper and a guide portion 25b for guiding the separated receipt paper in the direction of the transport belt are bent and formed in a Z-shape. The hinge portion 25a is fixed to a frame of a device (not shown) by screws, screws, welding, or the like.

If the separator 25 having such a shape is formed, it can be formed of resin. However, as shown in FIG. 1, the transport belt 23 is inclined so that the left side of the drawing, that is, the printing unit 29 side is lowered, in order to easily feed out the roll-shaped receipt paper. Therefore, when the roll receipt paper 22 is set on the main body hopper 20, the roll receipt paper 22 is constantly pressed against the separator 25 and is in contact therewith. However, the separator 23 can withstand contact friction, and is made of a resilient metal plate, for example, stainless steel (about 0.3 mm thick) so as not to damage the roll-shaped receipt paper 22 due to contact. Is formed. By forming it from a metal plate, it is several times more durable than that formed from a resin, specifically, about 1 million transactions,
In terms of time, even devices with a lot of transactions are 5-6
It is durable enough to withstand transactions that take place during the year.

The width w of the leading end of the separator 25 in contact with the roll-shaped receipt paper 22 is larger than the width W of the roll-shaped receipt paper 22 so that the separator 25 is easily brought into close contact with the roll-shaped receipt paper 22 as shown in FIG. It is formed narrow, is inclined from both ends of the width toward both sides, and the inclined side is bent upward at an obtuse angle. The inclination and the upward bending are for smoothly guiding the turned-up and uncut portions of the receipt paper in the transport direction without being caught by the portion.

As shown in FIG. 3C, the cross section of the tip of the separator 25 has an acute angle θ at the tip. This angle θ is suitably 45 degrees. 30 degrees, 6
When the experiment was performed at an angle of 0 degrees, at 30 degrees, the roll-shaped receipt paper was easily caught at a perforation, a notch, or the like, and the paper was torn. At 60 degrees, the paper is not torn, but it is difficult to separate the leading edge of the paper, and the separation efficiency is reduced. Furthermore, the angle θ of the tip of the separator 25
Is set to 45 degrees, stable production can be achieved.

Further, the tip portion is provided with a roundness R having a radius of about 0.05 to 0.1. When this roundness is confirmed by an experiment, if it is 0.05 or less, the roll-shaped receipt paper 22 is easily caught by a perforation, a notch, or the like, and the paper is damaged. On the other hand, if it is 0.1 or more, the separator 22 easily gets over the leading end of the roll-shaped receipt paper 22 while being stuck, and the leading end of the separator 25 cannot be hooked on the leading end of the roll-shaped receipt paper. Therefore, the efficiency of separating the leading end of the roll-shaped receipt paper decreases. Therefore, the radius of the tip is optimally about 0.05.

The width w of the leading end of the separator 25 is preferably about 1/2 to 1/5 of the width W of the roll receipt paper 22. This is because when the width w of the separator 25 is the same as the width of the roll receipt paper 22, and when the leading end of the roll receipt paper 22 is torn in the circumferential direction, a part of the roll 25 If the paper is separated from the paper and partially separated by the separator 25, the receipt is torn in the circumferential direction.
Further, if the width w of the separator 25 is reduced, an obstacle in which the sheet is broken can be avoided. However, since the roll-shaped receipt paper 22 is always in contact with the leading end of the separator 25, each time the roll-shaped receipt paper 22 rotates, the paper is damaged in the circumferential direction. In addition, the durability is deteriorated, and the roller 25 is worn by contact with the roll-shaped receipt paper 22, so that the separator 25 needs to be frequently replaced, and the operation efficiency of the apparatus deteriorates. Therefore, the width w of the separator 25, which is efficient and durable at the leading end of the roll-shaped receipt paper 22 and can reduce the breakage of the paper, is 1/2 to 1 times the width W of the roll-shaped receipt paper 22. Experiments have confirmed that about / 5 is optimal.

In the embodiment of the present invention configured as described above, when the rolled receipt paper 22 on the conveyor belt 23 is consumed in FIG. 1, the solenoids 28 and 28 'of the preliminary hopper 21 operate. By driving the levers 27 and 27 ', the preliminary receipt paper is replenished onto the transport belt 23, and the transport belt 23 separates the leading end of the roll-like receipt paper 22 in the direction of arrow A as shown in FIG. Is rotated, the tip of the receipt paper 22a is
The rotating impellers 31, 31 'forcibly guide the leading end of the receipt paper between the roll-shaped receipt paper 22 and the belt 23 to prevent a jam even if they protrude outside from the lower part of the paper 4, 24'. can do. In addition, the impeller 31,
31 'is flexible and does not hinder when the preliminary receipt paper is replenished onto the transport belt 23 from the preliminary hopper 21.

When the conveyor belt 23 rotates and the tip of the replenished rolled receipt paper 22 comes to the separator 25, the separator 25 easily separates the receipt paper 22a as shown in FIG. 4B. Can be. This is because the width of contact with the roll-shaped receipt paper is small and the R of the cross section at the leading end is small. In this case, the receipt paper 21 is not damaged due to the presence of R.

Further, as shown in FIG.
Even if there is a turn-over 22b, a cut-off residue 22c, etc. at the end of a, since it is inclined toward both sides from both ends of the end of the separator 25 and the edge thereof is bent upward, the guide portion 25b of the separator 25 The turned-up receipt sheet 22b, uncut portion 22c, and the like that pass under the lower side do not catch on the edge bent upward.

[0027]

According to the present invention, the receipt paper protruding from under the cover can be forcibly guided toward the transport belt by providing the impeller on the shaft supporting the transport belt. Of the tip section and the radius of the tip section are reduced, and the tip end is inclined from both ends to both sides. However, the leading end of the receipt paper from the roll-shaped receipt paper can be surely separated, and the occurrence of a jam can be prevented.
