Description

[Detailed description of the invention] The present invention relates to a device for reading pieces of paper such as train tickets, and the upper and lower sides of the paper piece have information such as date and time or section printed on one side as an optically readable bar code. The rotating belt transports the pieces of paper, and at the same time reads the barcode information by optical scanning, reliably transports and reads the paper pieces, reliably collects the pieces of paper, and makes the device compact. The purpose is to promote

There is a demand for a device that reads a passenger's ticket and automatically issues a new ticket if the ticket is correct, for transfers, etc.

The present invention relates to such a device, and one embodiment of the present invention will be described below with reference to the drawings.

In a device that has a collection box at the end of the conveyance section and collects paper pieces of tickets that are conveyed one after another, since paper pieces are extremely light and have almost no weight, it is necessary to use a belt to cover the front and back sides of the paper pieces, especially in the case of the present invention and embodiment. In a device that conveys paper by holding it between belts, paper pieces accumulate only in the vicinity of a place where the belt is no longer held.

When a piece of paper is inserted into the input port of the device, the belt rotates and the paper piece is conveyed and collected in a collection box at the back of the device.During the conveyance, information recorded on the side of the paper piece is read, and if the information is correct, the paper piece is read. One possible method is to let the paper pass through and collect it in a collection box, and if the information is incorrect, return the paper to the input slot again.

In this type of device, the pieces of paper are extremely light and have almost no weight, so when the pieces of paper that are conveyed while being pinched by the belt fall into the collection box at the rear end of the belt, they accumulate in that place, and the paper pieces that have accumulated are pushed away. It doesn't have the power to cut in, and it just piles up in one place.

Although some collection boxes are made deeper to increase the number of items stored, the above phenomenon cannot be avoided.

For this reason, when an incorrect piece of paper is thrown in and returned to the input slot by the reverse rotation of the belt without being collected, the back end of the belt does not fully enter the collection box and comes in contact with the belt. It has the disadvantage that regular pieces of paper are drawn together by the reverse rotation of the belt and returned to the input slot.

This is unreasonable, as the person who inserted the fraudulent piece of paper would not only have the fraudulent piece of paper returned to him/her after it has been read, but would also receive the legitimate piece of paper that the previous person had inserted.

In Figure 1, 1 is a piece of paper such as a railway ticket, and 2 is a piece of paper such as a railway ticket.
As shown in the figure and the back side in Figure 3, a barcode 1 that can optically read information such as date and time or section.
It is printed as '.

Reference numeral 8 denotes a motor for transporting paper pieces, and a belt 9 transmits driving force to a reduction pulley formed integrally with the boolean IJ7L.

Also, paper conveyance bells 7, 7' located on the back side of the paper 1 from the booth IJ7L are disposed on a pulley 7R, and are rotated to convey the paper.

Also located on the front side of the paper piece 1, a paper piece conveyance drive belt 7
There is a bell) 5.5' which is arranged to press against each of the bells) 7' and 7', which are wound around pulleys 5L and 5R to receive the rotational drive of the paper conveyance driving bell) 7.7'.
Both rotate to pinch and convey the piece of paper 1.

Also, bells) 6 and 6' are located on the back side of the piece of paper 1 and are arranged to press against bells) -5 and 5', respectively.
A bell) 5.5 which is wound around the pulleys 6L and 6R and receives the rotational drive of the above-mentioned paper conveyance drive bell) 7.7'.
It rotates to convey the piece of paper by obtaining driving force from '.

A space is provided between 6.6' and 7.7' on the back side of paper strip 1.

This is a space in which light such as the laser beam 12 is read and scanned, and when the piece of paper 1 is conveyed and passes over this space, the bar code printed on the back side of the piece of paper 1 is displayed. The purpose is to read information that has been converted into 1'.

Here, 11 is a laser oscillator, 13 is a mirror with a hole, 1
Reference numeral 4 designates a rotating mirror that scans the laser beam 12 from the laser oscillator 11 in a direction perpendicular to the conveyance direction of the paper strip 1 by means of a remoter 15, and reflects the laser beam so as to cross the barcode T printed on the back surface of the paper strip. Acts as a mirror.

16 is a phototransistor that reads the laser beam reflected by the piece of paper 1.

Reference numerals 3, 17, and 19 indicate light receiving sensors that receive light from the light emitting sensors 4, 18, and 20, which are configured to correspond to each other.

21 is a paper collection box.

By inserting a piece of paper 1 into the slot 2 formed in the frame with the front side printed with sections facing up and the back side printed with the barcode 1' facing down, the sensors 3 and 4 detect the paper piece. Detecting the input, the conveyor drive motor 8 is driven to convey the input paper piece, and the conveyor belt l-5, 5', 6, 6', 7, 7
' starts rotating.

Paper piece 1 is belt 5, 5' and 6, 6', later 5, 5' and 7
, 7 and conveyed toward the paper collection box 21.

At this time, the length of the paper strip 1 is detected by the sensors 3, 4 and the sensor 17, 18, which is arranged at a position approximately the length of the paper strip.
, 5' and 7, 7' is the so-called bell) 6.6' and 7
, 7', a laser beam 12 emitted from a laser oscillator 11 passes through a perforated mirror 13 and a rotating mirror 14, and directly scans the barcode 1' printed on the back side of the piece of paper.

The laser beam 12 that has scanned the barcode 1' is converged onto a phototransistor 16 as a reflected beam via a rotating mirror 14 and a perforated mirror 13.

Then, the output signal of the phototransistor 16 is converted into a numerical output by an amplifying and shaping circuit and a numerical determination circuit, and reading is completed.

The piece of paper continues to be conveyed, and when the leading edge of the piece of paper 1 in the conveyance direction is detected by the sensor 19, 20, the driving of the conveyance drive motor 8 is stopped and the conveyance of the piece of paper 1 is completed.

If the paper piece 1 is determined to be a regular piece of paper by the above-mentioned optical reading including the length, the paper piece 1 is temporarily held in the conveyance path and waits for the next operation.

If the length of the piece of paper is different or the printed barcode 1
When inputting an irregular piece of paper or a piece of paper that can be read because the information on It is returned to input port 2.

When the piece of paper 1 is removed, the drive motor 8 stops driving and waits for the next piece of paper to be inserted.

Further, the above-mentioned temporarily reserved regular paper pieces can also be returned to the paper piece input port 2 and taken out by pressing an optionally selected operation button (not shown).

The above-mentioned temporarily reserved regular pieces of paper are collected into the collection box 21 when the next piece of paper is thrown into the input slot and conveyance is started.

At this time, when the paper strip 1 is released from the grip of the bells 1-5, 5'7.7', the paper strip 1 is reliably collected into the collection box 21 by the paper strip sending section provided at the conveying end.

In FIG. 4, reference numeral 31 denotes a paper feed roller, which is fixed to a rotatable support shaft 35.

The support shaft 35 also includes a pulley 34 into which the one-way clutch 33 is press-fitted.

The pulley 34 receives the rotational drive of a pulley 36 formed integrally with the conveyance boob IJ7R via the belt 32.

Reference numerals 37 and 37' designate paper guide plates constituting the bearing portion 38 and guide the paper strips 1 in the width direction during conveyance.

Reference numeral 30 denotes a rotatable presser roller that is always pressed against the feed roller 31.

The regular piece of paper 1 detected by the detection sensors 19 and 20 and temporarily held is moved to the right in Fig. 1 when the next piece of paper is thrown into the input slot 2, detected by the sensors 3 and 4, and conveyed. As a result, the nipping and conveying relationship between the belts 5.5', 7, and 7' is disengaged, and the rotating paper feed roller 31 and pressing roller 3 receive drive transmission from the conveyor boot 7R.
0 and is forcibly pushed into the collection box 21, so that it can be collected reliably.

Further, the paper piece sending roller 31 is rotated by a one-way clutch only in the normal rotation direction of the conveyance pulley 7R, that is, the direction in which the paper piece 1 is fed into the collection box 21. When the conveyance boolean 177R is reversed, only the pulley 34 is rotated. The paper feed roller 31 does not rotate.

Next, another embodiment will be described using FIG. 5.

The drive of the paper piece feeding section is not carried out by transmission from the paper piece conveying drive as in the above embodiment, but a separate drive section is constructed to obtain the same effect.

Reference numeral 40 denotes a paper feed motor, and a paper piece feed roller 4
2 is fixed to a feed-out motor shaft 41, and the motor 40 always rotates in the forward rotation direction (the direction in which the last piece is conveyed to be collected in a collection box) during paper piece conveyance operation, and rotates intermittently. Although it moves, there is no problem even if it rotates all the time.

As described above, according to the present invention, since the paper pieces are forcibly sent to the collection box, the paper pieces can be collected reliably, and the collected paper pieces are separated from the paper piece conveying unit by the intervention of the paper piece sending unit, and the paper pieces are rotated correctly. By only rotating paper pieces, there is no need to re-enter the paper piece conveyance path as in the past, and even though illegal pieces of paper have been input, regular paper pieces collected in the collection box can be re-entered into the conveyance path and the paper pieces can be inserted into the paper piece input port. This eliminates the inconvenience that regular pieces of paper are transported backwards and used.

In addition, if the collection device were to only allow paper pieces to fall in, the collection box would be constructed deep to increase the number of sheets stored, but in this invention, the collection box is configured to be forced into the collection box by a feed roller that rotates only in the normal direction. Even if the depth is shallow, the number of sheets that can be stored increases.

Therefore, the paper collection box can be made small.
