Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] The present invention relates to a medium conveying device, wherein
If the media is conveyed to the middle of the two media detection sensors and cannot be detected by any of the media detection sensors, while the media is being held by the media transport rollers, the media transport rollers are reversed to eject the media, and then again. Whether the short medium or the medium is absent is determined based on whether or not the medium is detected by the first medium detection sensor so that the operator can take appropriate measures.

[Industrial applications]

Automatic cash handling machines have become popular in financial institutions, and cash transactions can be made only by inserting a passbook or a card into the device, and the contents of the transaction can be immediately recorded. In such an apparatus that handles a recording medium such as a passbook, the operator may mistakenly insert a medium other than the regulation or forcefully pull out the inserted medium. The present invention relates to a medium carrying device that can appropriately perform subsequent treatment when the device side determines that the medium is an abnormal medium.

[Conventional technology]

FIG. 4 is a diagram showing an outline of a conventional medium carrying device.
The medium transport path 1 is provided with medium transport rollers 3a and 3b of an MS (magnetic stripe read / write) unit 2 and a transport roller 5 of an ATP (automatic page turning) unit 4. Next to the ATP unit 4, an optical sensor 6 and a printer unit 7 are arranged.

Now, when a medium such as a passbook is inserted from the inlet 8, the MS
It is sucked by the transport rollers 3a and 3b of the unit 2, and the magnetic stripe of the medium is read at that time. Then, the conveyance roller 5 of the ATP unit 4 transfers it to the optical sensor 6, detects a page mark and a print line, and when page turning is required, it is returned to the ATP unit 4 again and page turning is automatically performed. Then, after turning the page, the print contents are printed on the medium by the printing unit 7 after passing through the optical sensor 6, and after the printing, the paper is discharged to the suction port 8.

By the way, only a predetermined medium is not always inserted into the transport path 1, and a medium other than the prescribed medium may be inserted erroneously or intentionally. In such a case, it is necessary to identify the medium as a non-standard medium in order to prevent the same processing as the standard medium. Therefore, the structure as shown in FIG. 5 is adopted.

That is, the first medium detection sensor A1 is arranged in front of the entrance-side conveyance roller 3a across the conveyance path, and the second medium detection sensor A2 is arranged in front of the inner conveyance roller 3b. . The distance between the medium detection sensors A1 and A2 is slightly longer than the length of the regular medium. These medium detection sensors A1, A2
The following control system is provided to detect the state of and control the medium. Reference numeral 9 denotes a control unit to which the detection signals of the medium detection sensors A1 and A2 are input. The control unit 9 controls the start / stop and the rotation direction of the pulse motor 10 that drives the transport rollers 3a and 3b. The control unit 9 is connected to the host computer via the line control unit 11.
Connected to 12. A timer 13 is connected to control the time of each part.

As shown in FIG. 6, when the medium 14 is inserted into the suction port 8, it is first detected by the medium detection sensor A1, and the pulse motor 10 is rotated forward by the detection signal, and the medium conveying roller 3a is operated to rotate the pulse motor 10. The medium 14 is inhaled. Immediately after the first medium detection sensor A1 is turned off, the innermost conveyance roller 3b
When it is also detected by the medium detection sensor A2 in front of, it is transferred to the next ATP unit 4 as a regular medium.

[Problems to be solved by the invention]

However, when the inserted medium 14 is shorter than the specified medium as shown in FIG. 7, even if the rear end of the medium passes the first medium detection sensor A1, the front end thereof is the next medium detection sensor A2. Not detected by. Therefore, after passing through the medium detection sensor A1,
Even if the time set by the timer 13 has elapsed, the next medium detection sensor A2 does not turn on. As a result pulse motor
10 stops, and as a medium error, the host computer
12 is notified, and the command is issued from the host computer 12, the device is canceled. Further, since the medium is located between the transport rollers 3a and 3b and cannot be controlled by the transport roller, the media cannot be used until an attendant comes and the medium jammed in the transport path is taken out.

Further, as shown in FIG. 8, even when the medium 14 once inserted is forcibly pulled out, after the first medium detection sensor A1 is turned off, the second medium detection sensor A2 cannot detect the state. Therefore, the medium is abnormal and the transaction is canceled.

FIG. 9 is a flowchart showing the above operation. Since the first medium detection sensor A1 detects the medium, the pulse motor 10 rotates in the suction direction, and immediately after the medium detection sensor A1 is turned off, the next medium detection sensor A2
When the leading edge of the medium is detected, the medium is continuously transferred to the MS unit and ATP unit side as a regular medium. If the second medium detection sensor A2 remains off, the pulse motor 10 stops due to a medium abnormality, and the host computer
12 will be notified.

As described above, conventionally, when a medium abnormality is detected, the apparatus is stopped to make it unusable, and the jammed medium is removed or inspected to confirm that there is no abnormality, and then the medium is restarted. However, if the apparatus is always stopped when a medium abnormality occurs in this way, the operating efficiency of the apparatus decreases and the service to the customer also deteriorates.

That is, in such a case, it is kind not to immediately disable the use, but to perform various checks, notify the operator of the cause, and appropriately guide the next action to be taken.

On the other hand, as described in Japanese Utility Model Laid-Open No. 58-167963, a medium that is shorter than a regular medium is not sucked into the device, or a card is pulled by a card like Japanese Patent Laid-Open No. 53-5700. It is known that the device automatically returns to its initial state immediately after being pulled out.

However, a device which does not suck a medium shorter than a regular medium into the device and which has both functions of automatically detecting the card being pulled out and immediately returning the device to the initial state has not been realized.

The technical problem of the present invention focuses on such a problem in the conventional medium conveying device, automatically ejects an abnormal medium in the medium conveying path, and when the medium is removed, After making it known to the customer, it is possible to continue the use of the device and to provide appropriate guidance to the operator.

[Means for solving problems]

FIG. 1 is a side view for explaining the basic principle of the medium carrying device according to the present invention. A medium carrying device of the present invention comprises a medium carrying means (3a) capable of carrying a medium in both forward and backward directions, a first medium detecting means (A1) for detecting the presence or absence of the medium, and a first medium detecting means ( It has a second medium detecting means (A2) arranged at a predetermined distance from A1) and detecting the presence or absence of a medium.

Further, based on the detection of the presence of the medium by the first medium detecting means (A1), the medium conveying means (3a) is operated in the direction for conveying the medium in the forward direction, and the first medium detecting means (A
When the second medium detecting means (A2) does not detect the presence of the medium within a predetermined time after counting 1) that the medium is absent, the medium conveying means (3a) If the first medium detecting means (A1) again detects that there is a medium, the medium is judged to be a short medium, and a signal instructing guidance according to the fact that the medium is a short medium is made. The first medium detecting means (A1)
If there is no medium, it is determined that there is no medium, and a control section (9) for sending a signal instructing guidance according to the absence of medium is included.

[Action]

According to the present invention, when the medium 14 is a short medium, the medium transport roller 3a reverses in a state where the medium 14 passes through the first medium detection sensor A1 and can be transported by the medium transport roller 3a. 14 is returned to the suction port 8. Therefore, the short medium is not left in the transport path 1. Also, when it is returned, it is detected again by the first medium detection sensor A1,
It is detected that the medium is a short medium, and the detection signal is notified to the host computer, so that the subsequent processing is performed as a short medium. If the first medium detection sensor A1 does not detect the medium, it means that the medium has been removed. By notifying the host computer of this detection signal, the subsequent processing is performed assuming that the medium has been removed.

As described above, according to the present invention, it is possible to identify whether the medium is a short medium or has been removed. Therefore, in the case of a short medium, the operator should instruct the host computer to insert a regular medium. Can be called up, and if the medium is removed, it can be prompted to reinsert it properly.

〔Example〕

Next, practical examples of how the medium conveying device according to the present invention is embodied will be described. FIG. 2 is a side view showing an embodiment of the device of the present invention, and the control of each part is performed by the control part 9 in FIG. FIG. 3 is a flow chart showing the operation in the same embodiment. Now Fig. 2 (a)
As described above, in the medium control device having the suction port 8,
When the medium 14 is inserted into the suction port 8 as shown in (b), the first medium detection sensor A1 is operated by the first medium detection sensor A1 in step S1 of FIG.
The medium 14 is detected, and as a result, the pulse motor 10 rotates in the forward direction, and the medium 14 is sucked by the medium conveying roller 3a. Then, when the medium 14 passes the first medium detection sensor A1, the medium detection sensor A1 is turned off. If this medium 14 is a regular medium, it is immediately detected by the second medium detection sensor A2 and the second medium detection sensor A2 is turned on. Then, the pulse motor 10 continues to rotate forward, and the medium
14 is transferred to a processing device 15 having a page turning unit 4 and a printing unit.

When the sucked medium 14 is a short medium as shown in (d), the second medium detection sensor A2 remains off in step S4, and the pulse motor 10 stops. Further, in order to return the short medium 14 to the suction port 8, the pulse motor 10 starts reverse rotation in step S6, and the medium transport roller 3a reverses as shown in (e) to discharge the medium 14 to the suction port 8. This reverse operation is performed until the set time of the timer 13 is reached. Further, the time is set so that the short medium is surely ejected within this set time. If the medium 14 is detected by the first medium detection sensor A1 in step S8 within this set time, it is detected that the medium is short, and the host computer is notified that the medium is short. As a result, it is possible to provide appropriate guidance, such as calling the operator's attention that “because it is a non-regular medium, insert a legitimate medium”.

Within the set time of the timer 13, the first medium detection sensor A1
If the medium is not detected at, the pulse motor 10 is stopped and the host computer 12 is notified that there is no medium. As a result, the operator can be urged to "re-insert the medium correctly because it has been removed."

〔The invention's effect〕

As described above, according to the present invention, when the sucked medium deviates from all the medium detecting means in the search target range and cannot be recognized in the middle of the conveying path, in the state where the medium can be controlled by the medium conveying means, By reversing the medium transfer means and returning the medium by a certain amount, and again by checking the presence or absence of the medium by the medium detecting means, whether the medium is a non-standard medium such as a short medium or the medium has disappeared due to forced extraction, Adopts a device to discriminate. Therefore, in the case of a non-standard medium, the device can be continued to be used by immediately ejecting it without taking it into the device. Further, when the medium is not detected by the medium detecting means during the ejecting operation, it means that the medium has been extracted. By notifying the host computer of the fact, the medium can be continuously used without stopping the apparatus. In addition, since it is possible to reliably determine whether the medium is short or whether the medium is removed in this way, it is possible to guide the operator to the next correct operation, which leads to the improvement of service for the customer. .
