Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic document issuing machine capable of automatically issuing various documents installed in, for example, a local government.
[0002]
[Prior art]
Conventionally, when a document is issued from a printing apparatus installed in an automatic document issuing machine such as an automatic certificate issuing machine, a plurality of sheets are sometimes sent in a superimposed manner. Although this is called double feed, this double feed is detected by irradiating the document discharged from the printing apparatus with infrared rays from the light emitting means and reflecting back to the document like a so-called reflective sensor. Infrared light is detected by a light receiving means arranged in the same direction as the light emitting means, and a determination is made as to whether or not double feeding is performed by measuring the distance between the sensor and the paper. That is, if double feed is occurring, the measurement distance is shorter than usual. Therefore, if the measurement distance is equal to or less than a certain value, it is determined that double feed is performed.
[0003]
[Problems to be solved by the invention]
However, in the conventional apparatus, there is a possibility that the sheet passing through the double feed detection portion in the apparatus described above may erroneously determine the measurement distance due to vibration or warpage of the sheet itself. That is, although the paper is not actually double-fed, the distance between the paper passing the detection portion and the sensor happens to fluctuate, so that the paper is not double-fed even though it is not double-fed. It will be misjudged that it is. Then, the printed paper that has not been double-fed is not discharged to the outside and is stored in the double-fed paper storage unit inside the automatic document issuing machine. Since the same document is printed again, the paper is wasted.
The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide an automatic document issuing machine capable of accurately detecting double feeding.
[0005]
[Means for Solving the Problems]
In order to achieve this object, an automatic document issuing machine according to claim 1 includes a transport path for transporting a document, and a multi-feed detection means for detecting a multi-feed of the document while the document is passing through the transport path. An automatic document issuing machine having the plurality of conveying means arranged at intervals along the conveying path, wherein the multi- feed detecting means is arranged at a place where the conveying path is curved , The curved portion of the conveying path is configured to protrude from a straight line connecting the conveying surfaces between the adjacent conveying means, and the double feed detecting means is disposed on the protruding side of the curved portion of the conveying path. Features. Therefore, the double feed detection means irradiates the paper passing through the curved portion of the conveyance path with infrared rays, detects the infrared rays reflected from the paper, and measures the distance between the paper and the double feed detection means, The presence or absence of double feeding can be determined. In this case, as described above, since the sheet passes while contacting the bottom surface of the curved portion, it is possible to prevent erroneous determination of double feeding based on erroneous determination of distance measurement.

Has been. Accordingly, the paper 100 passing through the transport path 55 always comes into contact with the bottom surface of the convex portion, and the distance from the double feed sensor 90 to the paper 100 is always kept constant during measurement. Therefore, when the passage position of the paper 100 fluctuates, it is not determined that the double feed is erroneously performed even though the double feed is not performed.
[0024]
Next, the electrical configuration of the automatic certificate issuing machine 1 will be described with reference to FIG.
[0025]
The automatic certificate issuing machine 1 according to the present embodiment operates according to a command from the CPU 13 connected to the host computer 31. The CPU 13 includes the card reader 2, the CRT display device 3, the touch panel 4, the coin mech 5, the bill validator 6, the call button 22, the journal printer 12 for printing a receipt, the operation method, and the like.

To have.
[0026]
The CPU 13 is connected to a paper transport unit 51, a paper discharge unit 71, and a double feed sensor 90.
[0027]
Next, the operation of the automatic certificate issuing machine 1 having the above configuration will be described.
[0028]
For the person who uses the automatic certificate issuing machine 1 by the normal CPU 13, the automatic certificate issuing machine 1 displays, for example, a screen in a mode “Please touch the screen” on the CRT display device 3 together with a still image. Is displayed (S1). The user sees this display screen and touches the touch panel 4 (S2: YES), whereby a card insertion screen is displayed on the CRT display device 3 (S3).
[0029]
When it is detected that the user inserts the ID card into the card insertion slot 2a of the automatic certificate issuing machine 1 (S4: YES), the CPU 13 detects the insertion of the ID card, and the card reader 2 reads the data. Instruct. The card reader 2 reads data recorded on the ID card and transfers the data to the CPU 13. The CPU 13 confirms whether or not the inserted ID card is a card for the automatic certificate issuing machine 1 (S5). If this card is not the card for the automatic certificate issuing machine 1 (S5: NO), the ID card is ejected from the card insertion slot 2a (S10), and the screen returns to the start screen (S1).
[0030]
On the other hand, if the ID card is a card for the automatic certificate issuing machine 1 (S5: YES), the CPU 13 displays a personal identification number input screen on the CRT display device 3. Further, a signal is also sent to the uttering device 16 to utter, for example, “Please enter your PIN” (S6). When it is detected that the user touches the touch panel 4 and enters a password (S7: YES). Then, the CPU 13 checks whether or not the password entered by the user matches the personal ID data of the ID card inserted into the card reader 2 (S8). If the password entered by the user is not correct as compared with the personal ID data of the ID card (S9: NO), the fact is transmitted to the CPU 13 and the ID card is discharged from the card insertion slot 2a (S10). At the same time, the screen returns to the start screen (S1).
[0031]
If the password entered by the user matches the personal ID data of the ID card (S9: YES), the fact is transmitted to the CPU 13. Next, the CPU 13 displays a certificate selection screen on the CRT display device 3 (S11).
[0032]
When it is detected that the user has selected the desired certificate (S11: YES), the CPU 13 displays a copy selection screen on the CRT display device 3 (S12).
[0033]
When it is detected that the user has selected a desired number of copies (S13: YES), the CPU 13 then displays a charge insertion screen on the CRT display device 3 (S14). When it is detected that the user has entered a predetermined fee (S15: YES), the CPU 13 then discharges the ID card from the card insertion slot 2a (S16). Subsequently, the personal data necessary for certificate creation received from the host computer 31 is transferred to the laser printer 11 and the certificate is printed (S17). Then, the certificate is conveyed through the conveyance path 55 (S18).
[0034]
Thereafter, the double feed sensor 90 detects whether or not a certificate passing through the transport path 55 is being double fed. In this case, as described above, since the conveyance path 55 at the detection position of the double feed is a convex portion, the certificate passing through the detection position is in contact with the bottom of the conveyance path 55 and is stabilized. Therefore, the measurement distance between the sensor detected by the double feed sensor 90 and the certificate is always constant, and the double feed is erroneously determined due to the change in the passing position of the certificate even though the double feed is not performed. Can be prevented.
[0035]
When the detection signal is received from the double feed sensor 90 because the certificate is double-fed (S19: YES), the separation chute 60 is switched (S23), and the certificate is sent to the double feed path 61 (S24). Then, the certificate creation operation from S17 is repeated. On the other hand, if the printed certificate is not double-fed (S19: NO), the certificate is sent out to the intermediate tray 56 through the conveyance path 55 (S20), and further, the discharge rollers 58a and 58b are rotated to discharge the certificate. It is sent out onto the tray 72 (S21). Then, the pressing tray 74 is lowered by a driving motor (not shown), and the discharge roller 73 and the pressing roller 75 are rotated to discharge the certificate to the certificate discharge port 7 (S22). Then go back to the start again.
[0036]
As described above, in this embodiment, the automatic certificate issuing machine 1 that issues a certificate has been described. However, the present invention is not limited to this, and any apparatus that automatically issues a document can be applied.
In this embodiment, a reflective sensor is used as the double feed sensor 90. However, the same effect can be expected by using a transmissive sensor for detecting the amount of light transmitted through the paper.
[0038]
【The invention's effect】
As is apparent from the above description, in the automatic document issuing machine according to claim 1, since the double feed detecting means is disposed on the protruding side of the curved portion of the transport path, the double feed detecting means is transported. Judging the presence or absence of double feed by irradiating the paper passing through the curved part of the path with infrared rays, detecting the infrared rays reflected from the paper, and measuring the distance between the paper and the double feed detection means Can do. In this case, as described above, since the sheet passes while contacting the bottom surface of the curved portion, it is possible to prevent erroneous determination of double feeding based on erroneous determination of distance measurement.
