Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper feeder for an automatic document issuing machine which automatically issues various documents.

[0002]

2. Description of the Related Art Recently, an automatic certificate issuing machine has been installed near the counter of a public office, and is very effective when the counter is crowded or when the office is closed on Saturdays. Such an automatic certificate issuing machine has an advantage that the applicant does not need to fill in the application form and can obtain the document in a relatively short time compared with the case where the person in charge at the counter processes it. When a certificate applicant obtains various certificates such as a resident's card or a seal stamp certificate using such a certificate automatic issuing machine, the applicant himself / herself can directly select the required documents while looking at the display. By inputting money, the certificate can be automatically obtained without going through the office window.

When the applicant selects a certificate using such a certificate automatic issuing machine, the issuing machine obtains information from the database connected to the host computer and starts printing, and the printed paper is stored inside. It is issued to the applicant through the paper transport passage. If the certificate issued at this time is composed of one sheet, the document will be delivered to the applicant's hand in the printed state and issued.
On the other hand, when a plurality of sheets are required even for one copy, the delivering machine binds these sheets with a stapler to make them into one sheet, and after issuing the signature, issues it to the applicant.

In this case, before binding the plurality of sheets of paper with a stapler, the width and length of the printed sheets of paper must be made uniform.

In this case, in the conventional automatic certificate issuing machines, the paper alignment method in the paper feeding direction is as shown in FIGS. 14 and 15, for example. When the sheets are stacked on the sheet receiving tray 100 and all the sheets are stored on the tray 100,
The paper holding claw 101 provided at one end of the paper receiving tray 100 drives the paper receiving tray 100 to push it out, and the paper is fed to the tray 100.
Send to the other end. Then, as shown in FIG. 15, the plurality of sheets are stapled by a stapler 102 installed above the other end of the tray 100. At this time, the leading end of the paper 103 is aligned by putting the tip of the paper in the back of the tray 100 and sandwiching the rear end of the paper with the paper pressing claw.

[0006]

However, in this method, as shown in FIG. 16, for example, when the sheets sent from the sheet feeding section are sequentially stacked in the sheet receiving tray 100, they are sent out first. The ejected paper may be pushed out by the paper sent later, and the leading edge of the paper may be displaced in the paper conveyance direction. Then, when the sheets are conveyed one after another, this operation may be repeated many times, and finally the leading end of the sheet 104 to be placed may be largely shifted back and forth. Then, when the sheet pressing claw 101 pushes out the sheet 104 in this state, as shown in FIG.
4 cannot be aligned and the sheet 104 that has been pushed out
Sometimes the tip of the was raised, bent, or curled. Then, the paper 104 may be stapled in a state in which it remains misaligned.

These problems become more serious as the number of sheets placed on the sheet receiving tray increases, since the sheets located below the stack receive the heavier weight of the sheets placed thereon.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to discharge a sheet with a cheap and simple mechanism while aligning the positions of the leading ends of the sheet size. It is an object to provide a paper device.

[0009]

In order to achieve this object, a sheet feeding device according to a first aspect of the present invention is a sheet feeding device having a stacking means for stacking sheets, and the sheets stacked on the stacking means. It is characterized in that it is provided with a position deviation prevention means for preventing the deviation of the position. Therefore, the sheet is conveyed in a state in which the position deviation preventing means aligns the positions of the plurality of sheets neatly.

The sheet feeding device according to a second aspect of the invention is the sheet feeding device according to the first aspect, wherein the misregistration preventing means includes a leading edge regulating means for preventing a misalignment of the leading edge of the sheet, And a trailing edge regulating means for preventing the trailing edge of the sheet from being displaced. Therefore, since the leading edge regulating means and the trailing edge regulating means prevent the positional deviation of the sheets to be conveyed, the plural sheets of paper can be prevented from being displaced and the sheets can be conveyed.

Further, the sheet feeding device according to claim 3 is the sheet feeding device according to claim 1 or 2, wherein the regulation position regulated by the leading edge regulation means is determined according to the size of the sheet. It is characterized in that it is provided with a regulation position determining means. Therefore, when the regulated position determining means needs to issue documents of various sizes, the regulated position is determined according to each size, so that the sizes of the respective sheets are conveyed in a state of being aligned accordingly. be able to.

Further, a sheet feeding device according to a fourth aspect is the sheet feeding device according to the first to third aspects, wherein the leading edge regulating means and the trailing edge regulating means are guided by the same guide. It is characterized by being. Therefore, since the leading edge regulating means and the trailing edge regulating means regulate the positions of the sheets with the same guide, the sheets can be surely aligned.

Further, a sheet feeding device according to a fifth aspect is the sheet feeding device according to any one of the first to fourth aspects, wherein the leading edge regulating means is provided from a stacking means to enable the conveyance of the sheets. It is characterized by evacuation. Therefore, by retracting the leading edge regulating means from the stacking means, a plurality of sheets can be conveyed in an aligned state.

Next, the operation of the automatic certificate issuing machine 1 in this embodiment until the certificate is issued will be described with reference to the flowcharts of FIGS. 9 and 10.

The automatic certificate issuing machine 1 normally causes the CPU 13 to display the card insertion screen on the CRT display device 3. The user inserts the ID card into the card insertion slot 2a of the automatic certificate issuing machine 1. The CPU 13 is the card reader 2
We constantly monitor whether an ID card is inserted in the
When the insertion of the ID card is detected (S1: S indicates a step. The same applies hereinafter), the card reader 2 is instructed to read the data. The card reader 2 reads the data recorded on the ID card and transfers the data to the CPU 13. The CPU 13 confirms whether the inserted ID card is a card for the automatic certificate issuing machine 1 (S2).
If this card is not the card for the automatic certificate issuing machine 1 (S2: NO), the ID card is ejected from the card insertion slot 2a (S3) and the fact is displayed on the CRT display device 3 (S4).

On the other hand, if the card is for the automatic certificate issuing machine 1 (S2: YES), the CPU 13 displays the personal identification number input screen on the CRT display device 3. In addition, a signal is also sent to the voicing device 16 to utter, for example, "Please input the personal identification number" (S5). Then, when it is detected that the user touches the touch panel 4 and inputs the personal identification number (S6), the CPU 13 sets the user ID identification code of the user recorded in the ID card and the input personal identification number to the host computer 31. To transmit. The host computer 31 collates the user ID identification code transmitted from the CPU 13 with the personal identification number (S7), and if the personal identification number is not correct for the user ID identification code (S8: N).
O), the fact is transmitted to the CPU 13, the password input screen is displayed again on the CRT display device 3 (S5), and the password is re-input.

On the other hand, if the personal identification number is correct (S8: YE
S), and informs the CPU 13 to that effect.

Next, the CPU 13 CRs the certificate selection screen.
It is displayed on the T display device 3. In addition, a signal is also sent to the voicing device 16 to utter, for example, "Please select a required certificate" (S10). When it is detected that the user selects the required certificate by touching the touch panel 4 on the portion where the required certificate is displayed (S11: YE
S) Next, the CPU 13 detects the size of the certificate selected by the user and stores the size in the hard disk 17 (S30). Then, the copy selection screen is displayed on the CRT display device 3. In addition, a signal is also sent to the voicing device 16 to utter, for example, "Please select the required number of copies" (S12). When it is detected that the user selects the required number of copies by touching the touch panel 4 (S13, Y
ES), the CPU 13 calculates the fee for the certificate selected by the user and displays the fee input screen on the CRT display device 3.
In addition, a signal is also sent to the voicing device 16 to utter, for example, "the charge is XX yen. Please pay" (S14).
Then, the user inputs a fee. If the charge is a coin, it is inserted from the coin insertion slot 5a and enters the coin mech 5. If it is a bill, it is inserted from the bill insertion slot 6a and enters the bill burr 6. At this time, if necessary, the change is paid out from the coin mech 5 and is discharged from the outlet 8. The hanging bill is paid out from the bill burr 6 and discharged from the bill insertion slot 6a. The receipt is printed by the journal printer 12 and discharged from the outlet 8.

When the CPU 13 confirms that the fee has been collected (S15, YES), the CPU 13 transmits a command to the card reader 2 to eject the ID card from the card insertion slot 2a. Then, when it is detected that the ID card is taken out, a screen notifying that the certificate is being created is displayed on the CRT display device 3. Further, a signal is also sent to the utterance device 16 to utter, for example, "Certificate is being created now, please wait for a while" (S17).

At the same time, the CPU 13 requests the host computer 31 for the data necessary for issuing the certificate. The host computer 31 is the database 3
2, the necessary information is extracted from the user ID identification code obtained from the ID card and the data such as the type of the document selected as described above, and the CPU 13 of the automatic certificate issuing machine 1
Send to

The CPU 13 sends the data transferred from the host computer 31 to the laser printer 11 for printing (S18).

Here, the certificate creation processing in S18 will be described with reference to the flowcharts of FIGS.

The CPU 13 prints the paper printed by the laser printer 11 onto the upper discharge port 1 of the laser printer 11.
Output from face down from 1a (S5
1). The paper output from the laser printer 11 is guided by the paper guide 54 and passes over the double feed sensor 77 (S52).

When the multifeed sensor 77 detects that there is a multifeed (S53: YES), the CPU 13
Switches the multi-feed switching lever 78 (S54), passes the multi-feed sheet that has passed through the transport path through the multi-transport transport path 79, and sends it to the storage section 11b (S55). After that, the same certificate creation process is performed again.

On the other hand, if the double feed sensor 77 does not detect the double feed (S53: NO), the paper is fed to the plurality of rubber rollers 5
5a and the pinch roller 55b are made to pass through the conveyance path 55 (S56).

Then, as a result of counting by the counter 90,
When the number of sheets that the applicant has applied is one (S5
7: YES), after the sheet is discharged face-up onto the sheet width aligning tray 56 from the transport path outlet 55c (S5).
7) and rotationally drive the motor 59 shown in FIG. 3 (S5
9), the paper pressing block 57 connected to the belt 58
Is slid to the left in FIG. 2 (S60). That is, the paper pressing claw 57a fixed to the paper pressing block 57 pushes the end of the paper on the width alignment tray 56 to the left. Then, the sheet is placed on the rubber roller 56a.
And the pinch roller 56b, and while rotating the rollers 56a and 56b, the discharge tray 61
It is sent up (S61). Then, the process returns to the main routine.

On the other hand, as a result of counting by the counter 90, when the number of sheets applied by the applicant is plural (S5
7: NO), the paper width alignment tray 56 is rotated about the fulcrum 56c as an axis to the position indicated by the chain double-dashed line (S62).

Then, the CPU 13 reads the paper size of the certificate selected by the user stored in S30 from the hard disk, outputs a signal to the positioning motor 83 based on the data, and the applicant selects it by the touch panel 4. The positioning motor 83 moves so that the stopper shaft 84 moves to the paper position corresponding to the paper size of the certificate.
Is driven to move the sheet positioning block 81 connected to the belt 82 to the sheet position (S64). That is, as shown in FIG. 5, the sheet positioning block 81 is moved along the guide pad 87 to a position corresponding to the sheet size selected by the user, and the stopper shaft 84 is projected from the sheet width alignment tray 56.

Then, the paper 50 is transferred to the transport path outlet 55c.
To the paper width alignment tray 56 at the position indicated by the two-dot chain line in the face-up state while being guided by the film 55d (S65). As a result, the leading edge of the fed sheet 50 is blocked by the stopper shaft 84 described above, and is regulated at the position where it abuts against the sheet pressing claw 5.
It is placed so as to fit in the area sandwiched by 7a.

In this case, even if a plurality of sheets of paper 50 are successively carried into the paper width alignment tray 56, as shown in FIG. 13, the paper which has been previously carried in and already placed on the tray 56 is the film 55d. Since the sheet is pressed down from above by the weight of, it is possible to prevent the sheet from swelling or rising when the sheet is loaded later. Further, since the sheets conveyed to the sheet width aligning tray 56 later are stacked on the placed sheets already regulated by the stopper shaft 84, the regulation by the stopper shaft 84 works, It is possible to prevent the tip of the sheet from shifting in the transport direction.

Therefore, a predetermined number of sheets of paper continuously carried into the paper width aligning tray 56 are placed on the paper aligning tray 56 in a state where the leading ends of the papers are already aligned at the stage when the carry-in is completed.

When the loading of the paper 50 is completed, the CPU 13
Drives the positioning motor 83 (S66) and moves the paper positioning block 81 connected to the belt 82 along the guide bar 60 to the storage space of the stopper shaft 84 (leftward in FIG. 2) (S67). And FIG.
As shown in FIG. 11, when the paper positioning block 81 contacts the origin switch 88 and turns on the origin switch 88 (S68: YES), the driving of the positioning motor 83 is stopped (S69 in FIG. 11). At this time, the stopper shaft 84 is retracted from above the paper width alignment tray 56 so as not to interfere with the conveyance of the paper due to the action of the compression spring 85.

Next, the paper moving motor 59 is rotationally driven (S70), and the paper pressing block 57 connected to the belt 58 is slid to the left in FIG. 2 along the guide bar 60 (S71). As a result, the paper pressing block 5
The paper pressing claw 57a fixed to 7 pushes the end of the paper to the left.

Then, the solenoid 71 is attracted and the pinch roller holder 73 is rotated clockwise by the link 72 to form a gap between the rubber roller 56a and the pinch roller 56b which have been nipped (S72). Then, the paper moving motor 59 is further rotated to rotate the paper pressing claw 57a.
The sheet pressed by is passed through the gap, and the leading edge of the sheet is inserted into the sheet insertion port 15a for tallying and stapling by the tally machine 15 and the stapler 14 (S73).

At the same time as the front end of the paper is abutted against the back of the paper insertion opening 15a by the paper pressing claw 57a, the sensor 91
When this is detected (S74: YES), the CPU 13 stops the rotation of the paper moving motor 59 (S7).
5) Based on the signal from the sensor 91, the width aligning plates 74 provided on the left and right of the paper aligning tray 56 are moved in the width direction of the paper by a driving unit (not shown), and a plurality of sheets on the paper aligning tray 56 are moved. Align the width of the paper (S7
6). The sheets are now aligned in front, back, left and right.

After that, the sheets are bound by the stapler 14 (S77) and then tally by the tally machine 15 (S78).

Then, the stapled and tipped paper is nipped between the rubber roller 56a and the pinch roller 56b and is sent to the right, and the leading end of the paper is pulled out from the paper insertion port 15a (S79). Then, the sheet aligning tray 56 is rotated counterclockwise about the fulcrum 56c and returned to the position shown by the solid line in FIG. 4 (S80). Then, the sheet is nipped by the rubber roller 56a and the pinch roller 56b, and is fed to the left side in FIG. 2 onto the sheet feed tray 61 (S8).
1). Then, the process returns to the main routine.

The CPU 13 of the certificate issuing machine 1 discharges the certificate created as described above from the certificate discharge port 7 (S19).

Here, the certificate discharging process in S19 will be described with reference to the flowchart in FIG.

Since the left side of the discharge tray 61 is inclined high, the discharged sheet slides down to the lower right, but is stopped by the sheet stopper 61b formed at the right end of the discharge tray 61. Then, a motor (not shown) is driven to slide the paper pressing unit 65 downward (S91).

Then, the process returns to the main routine.

The CPU 13 causes the certificate creation display screen to be CR.
The message is displayed on the T display device 3, and a signal is also sent to the voicing device 16 to utter "Certificate is complete. Please take care. Be careful not to forget receipts and cards." (S20). Then, it detects whether the certificate presented to the certificate outlet 7 is taken by the applicant,
When it is detected that the certificate has been taken (S21: YE
S), the CPU 13 displays an end screen (S22).
After a while, the same card insertion screen as above is displayed C
The image is displayed on the RT display device 3 and the above operation is repeated.

On the other hand, when it is detected that the certificate issued to the certificate outlet 7 is not taken by the applicant even after a predetermined time has passed (S21: NO), the CPU 13 inserts the certificate into the certificate outlet 7. Collect the issued certificate internally (S2
3) Store in the collection tray 76. Remote panel 3
3 is provided in the hand of the person in charge, and when the user presses the call button 22 or when the certificate automatic issuing machine 1 runs out of printing paper, for example,
Notify the person in charge of the situation with a lamp or chime.

As described above, in the automatic certificate issuing machine 1 according to the embodiment of the present invention, the CPU 13 detects the size of the certificate selected by the user and moves the paper positioning block 81 based on the detected size. The front and rear alignment of the sheets is performed simply by loading the sheets onto the width alignment tray 56. Therefore, it is not necessary to align the sheets in the front-rear direction again after the sheets have been loaded, and the mechanism and processing of the apparatus can be simplified accordingly.

As described above, the above embodiment shows an example in which the present invention is embodied. However, the present invention is not limited to this embodiment and can be modified without departing from the spirit of the present invention.

In this embodiment, the stopper shaft 84 is constantly subjected to a downward force by the compression spring 85. However, without using the compression spring 85, the weight of the stopper shaft 84 causes the paper width aligning tray 56 to move. You may make it descend | fall to the position which retreats from a paper conveyance surface. Further, in the present embodiment, the paper positioning block 82 uses the same guide bar as the two guide bars 60 for moving the paper pressing block 57, but a guide bar dedicated to the paper positioning block 82 is provided. But there is no problem.
