  The best mode for carrying out the present invention will be described below based on examples with reference to the drawings.

  A first embodiment of the present invention will be described with reference to FIGS.

  In the present invention, an RFID (Radio Frequency Identification) system is used to achieve the object.

  More specifically, it is a system that uses a contactless IC card to perform wireless personal authentication.

  FIG. 1 shows an image forming apparatus using an RFID system.

  The image forming apparatus 1 includes a document feeder 2, a paper cassette 10, an image forming unit 4, a finisher unit 5, and the like.

  First, the copy operation will be described.

  When a document is set on the document tray 6 of the document feeder 2 and the copy button is pressed, the image reading operation is started.

  The paper fed from the paper cassette 10 is sent to the image forming unit 4 by the transport roller, where a toner image read on the paper is formed and output onto the paper discharge tray.

  In the case of a printer operation, as shown in the flowchart of FIG. 3, instead of the above-described document reading operation, an image transmitted by a command from a personal computer (not shown) connected to the host computer 3 via a LAN is used as ID information. At the same time, it is stored in the storage device 307.

  Next, FIG. 2 is a hardware block diagram showing the configuration of the image forming apparatus described in FIG. In FIG. 2, reference numeral 301 denotes a CPU, which executes a control program stored in a ROM 306 that is a read-only memory and controls the blocks 302 to 307. A memory 302 is a RAM that is a read / write memory that stores information necessary for the CPU 301 to control. The CPU 301 executes the control program stored in the ROM 306, thereby reading the document by the document reading device 16, converting it into digital image data, and storing it in the storage device 307. The storage device 307 is realized by a hard disk, a magneto-optical disk, or the like.

  Similarly, the image data stored in the storage device 307 is formed as a visible image on the sheet by the image forming apparatus main body 1 by executing a control program stored in the ROM 306 by the CPU 301. A communication I / F 304 controls a procedure for exchanging control information with the finisher unit 5. Reference numeral 308 denotes an I / O, which outputs an ON / OFF signal to the clutch, solenoid, and the like constituting the image forming apparatus main body 1 according to the control of the CPU 301 and transmits the sensor signal to the CPU 301.

  Next, RFID (personal authentication) will be described.

  A communication device 9 is built in the image forming apparatus 1 connected to the host computer 3 via a LAN.

  An IC card 12 is built in the ID card 8 worn by the operator 7, and the personal ID is stored in this chip.

  The communication apparatus 9 and the IC chip 12 communicate to perform personal authentication.

  The communication distance of RFID varies from contact to several meters, but in this embodiment, it is set to about 2 meters.

  The ID card 8 is preferably one that is always worn by the operator, such as an employee ID card or student ID card.

  Next, the inside of the ID card 8 will be described in detail with reference to FIG.

  The ID card 8 includes an IC chip 12 that includes an EEPROM, CPU, RAM, and the like for storing data.

  A mechanism for authenticating an operator using this personal authentication system and selecting and outputting an unoutput print in the storage device 9 will be described with reference to the flowchart of FIG.

  The communication device 9 built in the image forming apparatus 1 transmits an ID read command to the ID card 8 (step S1).

  In this state, when the operator 7 wearing the ID card 8 approaches the image forming apparatus 1, it is within a communicable distance, and the communication apparatus 9 receives the ID read command of the ID card 8 (step S2). Next, if there is a JOB corresponding to the ID code among the non-output JOBs stored in the memory of the storage device 9 (step S3), it is selected and printing is started and an image corresponding to the approaching operator is displayed. Then, the output paper is discharged (step S4).

  Further, the output paper may be discharged by post-processing such as stapling or punching, which will be described later, in the finisher 5.

  In this way, a plurality of JOB print papers are temporarily stored in the storage device 9, and only the image data sent by the operator is selected and an image is formed by personally recognizing the operator approaching to take the print paper. Since the prints can be smoothly discharged onto the stack tray, high operability is ensured, and print paper that is forgotten to be removed is not stacked on the stack portion.

[Other embodiments]
Another embodiment will be described with reference to FIGS.

  As in the flowchart shown in FIG. 6, in the case of a printer operation, an image transmitted by an instruction (step S11) from a personal computer (not shown) is formed by the image forming unit 4 as in the present embodiment. The printing operation is started. (Step S12) The output sheet is temporarily stacked on the circulation discharge tray 15 of the finisher 5 (Step S13), and at the same time, the print ID corresponding to the stacked sheets is stored (Step S14).

  The circulation discharge tray 15 can stack a plurality of JOB sheets, and stores an ID corresponding to each JOB, the number of sheets, and a position in the circulation discharge tray 15.

  Next, a mechanism for authenticating an operator using a personal authentication system, selecting a print in the circulation discharge tray 15 and discharging the print will be described with reference to the flowchart of FIG.

  The communication device 9 built in the image forming apparatus 1 transmits an ID read command to the ID card 8 (step S21).

  In this state, when the operator 7 wearing the ID card 8 approaches the image forming apparatus 1, it is within a communicable distance, and the communication apparatus 9 receives the ID read command of the ID card 8 (step S22). Next, if there is a JOB corresponding to the ID code among the undischarged JOBs stacked on the circulation discharge tray 15 (step S23), it is selected and the output paper corresponding to the approaching operator is discharged (step S23). S24).

  When it is ejected, the information in the storage device is rewritten. Further, the output paper may be discharged by post-processing such as stapling processing, which will be described later, in the finisher 5. Further, the operator himself / herself may input the ID code password code at the operation unit of the image forming apparatus, and then the discharging process may be performed. The setting can be changed by the operator's computer or the image forming apparatus.

  In FIG. 8, the mechanism part of the finisher 5 will be described. A finisher 5 serving as a sheet processing apparatus is disposed on the side of the printer main body 1 and is used for various operations such as alignment, stapling, punching, and the like for sheets discharged from the printer main body 1 or a stack of sheets stacked on a plurality of sheets. Post-processing is performed. The finisher 5 may be configured to perform only the alignment process or only the alignment process and the stapling process.

  The entrance roller pair 52 receives the sheet P discharged from the discharge roller pair 399 of the printer main body 1. The conveyance roller pair 53 continuously conveys the received sheet P. The sheet detection sensor 31 detects the passage of the sheet P conveyed by the conveyance roller pair 53.

  Thereafter, the punching unit 50 opens a hole in the vicinity of the rear end of the sheet based on the sheet detection sensor 31 detecting the passage of the sheet. The punching unit 50 does not necessarily need to punch holes in the sheet.

  The switching flapper 61 switches between the non-sort path 21 and the sort path 22. The switching flapper 60 switches between the sort path 22 and the buffer path 23 for temporarily storing sheets P. When the switching flapper 60 selects the buffer path 23, the pressing rollers 62, 63, 64 arranged around the outer periphery of the relatively large-diameter buffer roller 5 press the sheet with the holes formed outside the buffer roller 55. The buffer roller 55 is temporarily stored on the outer periphery. Thereafter, the conveyance roller pair 56 conveys the sheet guided into the sort path 22 by the switching flapper 60 to the discharge roller pair 66.

  The processing tray (sheet stacking unit) 130 temporarily stacks the sheets P sequentially discharged from the discharge roller pair 66 in a bundle shape. A stapling unit (sheet post-processing device, sheet binding device) 101 performs stapling processing on a sheet stacked on the processing tray 130 with a stapler (not shown).

  When the staple unit 101 performs the stapling process on the sheet bundle, if the length of the sheet is long in the left-right direction in FIG. 8, the sheet may protrude from the processing tray 130 and may be misaligned or dropped. For this reason, when the sheet is long, the protruding sheet support tray (projecting sheet support means) 170 disposed below the processing tray 130 protrudes from the main body 51 to support the protruding portion of the sheet. The processing tray 130, the protruding sheet support tray 170, and the configuration and operation related to these trays will be described later.

  The bundle discharge roller pair (sheet discharge means) 180 includes a roller 180 a disposed on the processing tray 130 and a roller 180 b supported by the swing guide 150, and staples the sheet bundle on the processing tray 130. Then, the roller 180b is brought close to the roller 180a to sandwich the sheet bundle, and is discharged onto the stack tray 14 by the rotation of the rollers 180a and 180b. At this time, the protruding sheet support tray 170 is retracted to the standby position because it interferes with sheet bundle discharge.

  On the other hand, the discharge roller 59 at the top of the finisher 5 discharges the sheet guided to the non-sort path 21 by the switching flapper 61 onto the sample tray 13.

[Description of the area around the processing tray and protruding sheet support tray]
In FIG. 9, there are a rear end stopper (end portion aligning means) 131 that is tiltably disposed at the rear end of the processing tray 130, and a side that aligns the side portions of the sheet bundle on the processing tray 130. A portion alignment unit (side alignment means) 140, a swing guide 150 swinging above the processing tray 130, a pull-in paddle 160 for returning the sheet discharged from the discharge roller pair 66 to the trailing end stopper 131, and the processing tray 130 below. A protruding sheet support tray 170 and a bundle discharge roller pair 180 are provided.

  The sheet stacking surface 130a of the processing tray 130 is inclined with the downstream side (left side in the figure) upward and the upstream side (right side in the figure) downward. The side alignment unit 140 aligns the side portions along the sheet conveyance direction, and is not necessarily required when the sheets are discharged on the processing tray 130 with the side portions aligned.

  The protruding sheet support tray 170 is disposed between the processing tray 130 and the stack tray 14. The protruding sheet support tray 170 protrudes and retracts from the main body 51 of the finisher 5 along the sheet conveyance direction (arrow X direction) while following the inclination of the processing tray 130 below the roller 180a. Further, the protruding sheet support tray 170 is in the protruding state, and the leading end 170a overlaps the stack tray 14 side. In the retracted state, the leading end 170a is retracted from the bundle discharge roller pair 180 to the inside of the finisher body 51. ing. The leading end 170a of the protruding sheet support tray 170 in the protruding state is positioned downstream (left side in the drawing) from the center of gravity of the sheet bundle placed on the processing tray 130.

  The swing guide 150 is pivotally supported on the swing support shaft 151 on the upstream side (right side in the figure), and swings in the vertical direction as the rotating cam 152 connected to the motor M150 rotates. Yes. Further, when the sheet is discharged to the processing tray 130, the swing guide 150 is configured such that the roller 180b is separated from the roller 180b so as not to interfere with discharge and alignment of the sheet. When the sheet bundle is discharged from the processing tray 130, the swing guide 150 rotates to bring the roller 180b close to the roller 180a and closes the sheet bundle, and the both rollers 180b and 180a sandwich the sheet bundle. It is designed to be transported. The rollers 180a and 180b of the bundle discharge roller pair 180 are driven forward and backward by receiving a drive from the motor M180.

[Explanation of stack tray and sample tray]
As shown in FIG. 8, the stack tray 14 and the sample tray 13 are both moved up and down independently by motors M200 and M201. The finisher body 5 includes a sheet upper surface detection sensor 204 that detects the upper surface of the sheet discharged to the sample tray 13, a sheet upper surface detection sensor 205 that detects the upper surface of the sheet discharged to the stack tray 14, and each sensor described later. Is provided.

  The sample tray 13 is moved up and down between a pair of upper and lower sheet upper surface detection sensors 204 and 205, but the upper limit is restricted by an upper limit sensor 203 a disposed near the discharge roller 9, and when about 1000 sheets are stacked. Normally, the number of stacked sheets is limited by the lower limit sensor 203b arranged at a position corresponding to the above.

  The stack tray 14 moves up and down between the sheet upper surface detection sensor 205 and the lower limit sensor 203c. The lowering of the stack tray 14 limits the number of stacked sheets by the height, and therefore the sensor 203c is arranged at a position corresponding to the case where about 1000 sheets are stacked.

  The sample tray 13 and the stack tray 14 are provided with a sheet presence / absence detection sensor 206 that detects whether or not sheets are stacked.

  Normally, the sample tray 13 stands by at the position of the sheet upper surface detection sensor 204, and the stack tray 14 stands by at the position of the sheet upper surface detection sensor 205. Normally, the stack tray 14 stacks sheets discharged from the processing tray 130. The stack tray 14 can receive sheets processed by the staple unit 101 and a bundle of sheets that are ejected in small numbers without being bound.

  The position where the optical axis of the sheet upper surface detection sensors 204 and 205 comes to the upper surface of the sample tray 13 and the stack tray 14 or a predetermined distance (for example, about 1 mm) above the uppermost surface of the sheet bundle on the sample tray 13 and the stack tray 14. This is the initial position of the sample tray 13 and the stack tray 14. Therefore, each time a sheet is stacked on the sample tray 13 and the stack tray 14, the sample tray 13 and the stack tray 14 are lowered until the sheet upper surface detection sensors 204 and 205 are not blocked by the sheet. The tray 14 is held at the initial position.

[Description of circulating stack tray]
The circulation stack tray 15 is a mailbox tray on which sheets printed out by a plurality of operators are collectively stacked. The operation will be described later. A path switching flapper 501 is provided downstream of the pair of inlet rollers 52. When the sheet is directed toward the stack tray and the sample tray, the sheet is deflected upward in the drawing, and when toward the circulation stack tray 15, the sheet trailing edge is provided with the flapper 501. After passing, it is switched back by the conveying roller pair 53 and heads downward. The sheet deflected downward in the drawing passes through a path 503 and is guided downstream by a switchback roller 504. The conveyance roller 53 and the switchback roller 504 can be driven forward and backward.

  Since the reference numeral 505 is a switchback flapper and is always urged to the position of the solid line in the figure, the sheet conveyed by the switchback roller 504 is deflected to the path 506 side. The sheets discharged to the circulation stack tray 15 by the paper discharge roller 507 are brought into contact with the abutting guide 511 by the rotation of the alignment roller 508 and aligned. The aligning roller 508 can be rotated and moved up and down, and contacts the upper surface of the sheet only during alignment.

  The plurality of sheets stacked on the circulation stack tray 15 are on standby until the operator comes to pick them up. A sheet feeding belt 513 is provided on the lower surface of the circulation stack tray 15 to feed sheets stacked on the circulation stack tray 15. Further, the paper is separated and fed one by one by a pair of separation paper feed rollers 515 and conveyed upward in the figure by a pair of conveyance rollers 516 and 517. When discharged to the sample tray 13 or the stack tray 14, the paper is guided from the switchback roller 504 to the conveyance roller pair 3 through the path 502. When the sheets are stacked again on the circulation stack tray 15, after the trailing edge of the sheet comes off from the switchback flapper 505, the switchback roller 504 is reversed and sent to the path 506 side.

  The circulation stack tray 15 is provided with a rotatable lid 510 so that an operator cannot access it. Usually, an electromagnetic lock (not shown) is applied, but when a paper jam occurs, the lock can be released and the sheet can be taken out. .

[Sheet stacking operation on the processing tray]
As shown in FIG. 10A, the sheet that has passed through the large conveying roller 55 is sent to the sort path 22 by the switching flapper 60 and discharged onto the processing tray 130 by the discharge roller pair 66.

  The sheet discharged from the discharge roller pair 66 slides down on the processing tray 130 until the rear end of the sheet comes into contact with the rear end stopper 131 (see FIG. 9) due to its own weight and the rotational contact of the paddle 160. The rear end stopper 131 receives the sheet and aligns the upstream end of the sheet. At this time, the protruding sheet support tray 170 is in a protruding state, and prevents the leading edge of the sheets stacked on the processing tray 130 from hanging down and causing a return failure, and improves the alignment of the sheets on the processing tray 130. . When a predetermined number of sheets are stacked and aligned on the processing tray 130, stapling is performed at one place by the stapling unit 101 as necessary at this point. When the staple unit 101 staples the sheet bundle, the rear end stopper 131 (see FIG. 9) rotates from the position indicated by the solid line to the position indicated by the broken line and retracts below the processing tray 130.

  Then, as shown in FIG. 10B, the swing guide 150 is lowered, and the roller 180b is placed on the sheet bundle. Thereafter, the second stapling is performed as necessary.

  The retraction timing of the protruding sheet support tray 170 is when the first stapling is completed. As shown in FIG. 11, the protruding sheet support tray 170 prevents the alignment bundle P from curving downward. However, if the protruding sheet support tray 170 is retracted before stapling, it is shown in FIG. In this way, there is a risk that the uppermost sheet and some of the sheets below the uppermost sheet will be shifted as indicated by the symbol Y. This shift phenomenon appears prominently in proportion to the number of sheets stacked. In particular, the sheet appears remarkably when it is curled in an inverted U shape.

  The most preferable retraction timing of the protruding sheet support tray 170 is just before the bundle discharge roller pair 180 starts the operation of discharging the sheet bundle after the stapling unit 101 performs the stapling process at all predetermined positions. With such a timing, it is possible to reliably staple the sheet bundle, and it is possible to reliably prevent the curved deformation due to the hanging of the sheet bundle.

  As shown in FIG. 13, when the number of sheets discharged in a bundle is equal to or greater than a predetermined number, the stack tray 14 is rotated by a motor M200 (see FIG. 8) before the bundle discharge and the protruding sheet support tray. Before 170 retreats, it rises a predetermined distance and stops at the correction position shown in the figure.

  There is a small drop L1 between the sheet bundle P0 and the stack tray 14 discharged at this time. This prevents the leading edge of the sheet bundle to be discharged from coming into contact with a sheet bundle (not shown) and curling, and prevents the lowest sheet of the discharged sheet bundle from buckling due to a drop. Yes.

  Thereafter, as shown in FIG. 14A, the bundle discharge roller pair 180 rotates to discharge the sheet bundle P <b> 0 to the stack tray 14. At this time, in order to drop the sheet bundle onto the stack tray 14, the protruding sheet support tray 170 is retracted to the retracted position before the sheet bundle is removed from the bundle discharge roller 180. When the sheet bundle P0 is stacked on the stack tray 14 at a height that blocks the sheet upper surface detection sensor 205 as shown in FIG. 14B, the control device 4 causes the uppermost sheet to be detected by the sheet upper surface detection sensor 205. The stack tray 14 is lowered until the surface is detected. When the upper surface of the stacked sheets falls below a predetermined position, the protruding sheet support tray 170 protrudes from the main body of the finisher 5 in order to support the next discharged sheet.

[Description of circulation stack tray operation]
As shown in FIG. 15, the printed sheets are temporarily stacked on the circulation stack tray 15. For example, the operator who outputs the sheet Pa is stored in the circulation stack tray until it is picked up. Although it can be discharged to the sample tray or the stack tray as specified by the operator, the default is discharged to the circulation stack tray 15. In the state shown in the drawing, the sheet Pb as the next job is discharged to the circulation stack tray 15. Sheets Pa and Pb are sheets output by different operators. Although the length of the sheet is different, the sheet is abutted and aligned with the abutting guide 511 by the alignment roller 508.

  FIG. 16 shows a state in which the sheet Pa is discharged to the sample tray 13 side. The stacked sheets Pa are fed in order from the bottom sheet by the sheet feeding belt 513 and guided to the upper path in the figure by the conveying rollers 516 and 517 and the switchback roller 504. When the discharge of the sheet Pa is completed, the apparatus stops. The operation of discharging the sheet Pa is started after the communication device 9 detects that the operator who printed the sheet Pa has approached the apparatus. Since the discharge operation is started after detecting that the operator is approaching, all the sheets Pa are completely discharged to the sample tray 13 when reaching the front of the apparatus.

  FIG. 17 shows a state where the sheet Pa is reloaded onto the circulation stack tray 15 when the operator who printed the sheet Pb approaches the apparatus. The sheets Pa are fed in order from the bottom sheet, switched back by the switchback roller 504, and discharged onto the upper surface of the sheet Pd. When the discharge of the sheet Pa is completed, the sheets Pb are sequentially fed, guided to the upper path in the figure without performing switchback, and discharged to the sample tray 13 side. When post-stapling is performed, the staple is stacked on the processing tray 130 and then stacked on the stack tray 14.

  The ID code corresponding to JOB such as sheets Pa, Pc, Pd, the order in which the sheets Pa, Pc, Pd are stacked on the circulation stack tray, and the number of JOBs are stored in the image forming system, and are prepared for the next paper discharge processing operation. ing.

  In this way, as in the present embodiment, a plurality of JOB print sheets are temporarily stacked on the circulation stack tray 15, and an operator approaching to take the print sheets is recognized personally, and only the sheets output by the operator are smooth. The stack tray is discharged and the operator can easily take out his print paper.
