Description

  The present invention relates to a stencil box for storing used masters peeled off from a plate cylinder, and more particularly to a stencil box capable of making a used master unreadable and a stencil printing apparatus using the same.

  In a conventional stencil printing device, when a new document is printed, the evacuation part first operates, and after the used master wound on the plate cylinder is peeled off and stored in the stencil box, the stencil part operates. Then, plate making is performed on a new master and this is wound around the plate cylinder. The used master stored in the discharging box is managed by a sensor provided in the discharging part, and is discarded when the discharging box is full. Disposal of used master from the stencil box is done manually. The operator removes the stencil box from the main body of the stencil printing machine and discards the stored used master in the trash, and then empties the stencil again. Attach to the printer body.

  In this way, the used master is stored in the discharge box after being peeled from the plate cylinder in the discharge unit, and is stored in the recycle box when the discharge box is full. It is possible to take out the used master discarded in the trash box and check the contents of the plate making. Therefore, if the master stored in the plate removal box requires confidentiality, the confidentiality may be leaked.

  In order to solve the above-mentioned problems, a damaged member that comes into contact with the used master that is peeled off from the plate cylinder is provided in the discharged plate portion, and the used master is damaged by the damaged member during the discharging operation. A technique for making confirmation impossible is disclosed in, for example, “Patent Document 1”. However, the technique disclosed in “Patent Document 1” has a problem that the used master is easily jammed because the used master is damaged in the vicinity of the entrance of the discharge box for taking in the used master. . Then, it has a winding member which winds up the used master peeled off from the plate cylinder, and when this winding member is removed from the apparatus main body, the used master wound around the winding member is damaged. For example, “Patent Document 2” discloses a technique that makes it impossible to confirm the contents of the above.

The operator presses the security key 65 prior to pressing the plate-making start key 59 when making plate-making of a confidential printed material. The security key 65 is a toggle switch that is turned on when it is pressed once and the “ON” LED is lit, and when pressed again, it is turned off and the “OFF” LED is lit.

Based on the above configuration, the operation of the stencil printing apparatus 22 will be described below.
After the manuscript is placed on the contact glass 52 by the operator, when the plate making start key 59 is pressed with the pressure plate 53 closed, the image reading unit 28 reads the manuscript image. Reading is performed by scanning the original image with the scanning unit 54, and the read image is converged by the lens 55 and then sent to the image sensor 56.

  In parallel with the reading operation, the plate discharging unit 26 performs a plate discharging operation for peeling the used master 5 from the outer peripheral surface of the plate cylinder 30. When the plate making start key 59 is pressed, the plate cylinder 30 rotates, and when the predetermined plate discharging position is reached, the rotation of the plate cylinder 30 is stopped. Then, the plate removal member 48 moves to the peeling position, the used master 5 on the plate cylinder 30 is scooped up, the plate cylinder 30 rotates, and the plate removal member 48 operates to store the used master 5 in the plate release box 1. The The plate cylinder 30 rotates to a predetermined plate feeding position and stops, the clamper 33 is opened, and the stencil printing apparatus 22 enters a plate feeding standby state.

  Thereafter, the plate making unit 24 is operated, and the master 35 drawn from the master roll is conveyed toward the clamper 33 while being made by the thermal head 39. When it is determined from the number of steps of the stepping motor 37 that the tip of the master 35 has been transported to a position where it can be held by the clamper 33, the clamper 33 is closed and the master 35 places its tip on the outer peripheral surface of the plate cylinder 30. Retained. After holding the master 35, the plate cylinder 30 rotates and the master 35 is wound around the plate cylinder 30. When the master 35 for one plate is made, the master cutting means 40 is activated to cut the master 35. The cut master 35 is pulled out of the plate making section 24 by the rotation of the plate cylinder 30 and the plate cylinder 30 is rotated to a predetermined home position and stopped to complete the plate making and plate feeding operations.

  The printing operation is performed following the plate feeding operation. When the plate cylinder 30 is stopped at the home position, the paper feeding unit 25 is operated to separate and feed one sheet P, and the fed sheet P is temporarily stopped by the registration roller pair 47. Thereafter, the plate cylinder 30 is rotationally driven at a low speed, and the registration roller pair 47 is operated at a predetermined timing, whereby the paper P is fed toward the contact portion between the plate cylinder 30 and the press roller 31. Almost simultaneously with the operation of the registration roller pair 47, the press roller 31 is pressed against the plate cylinder 30, and the fed paper P is pressed against the master 35 on the plate cylinder 30. By this pressing operation, the press roller 31, the paper P, the master 35, and the plate cylinder 30 are brought into pressure contact, and the ink supplied to the inner peripheral surface of the plate cylinder 30 by the ink supply means 32 is transferred to the paper P, so-called printing. Done. The paper P on which the image is transferred is peeled off from the outer peripheral surface of the plate cylinder 30 by the peeling claw 49, transported to the paper transport means 50, and discharged onto the paper discharge tray 51. Thereafter, the plate cylinder 30 rotates to the home position again and stops, and the stencil printing apparatus 22 enters a print standby state.

  When the printing start key 60 is pressed after the number of prints is set by the ten key 62 after the stencil printing apparatus 22 enters the print standby state, the paper P is continuously fed from the paper supply unit 25 and printed. Operation is performed. When the set number of prints is consumed, the plate cylinder 30 is again stopped at the home position, and the stencil printing apparatus 22 is again in a print standby state.

  When the security key 65 is pressed prior to the above-described plate making operation, the stencil printing apparatus 22 enters a security mode, and confidentiality is maintained for the master 35 that has been made thereafter. When the master made after the security mode is set is discharged, the master stored in the discharge box 1 is cut through the master discharging means 4 on the display device 64 as shown in FIG. A message is displayed prompting you to dispose of the product in a discarded state. Thereby, it is possible to prevent leakage of confidential information from the used master. In the present embodiment, an example in which the discharge box 1 is used is shown, but a discharge box 9 may be used.

  In the third embodiment, the used master is damaged when the master made after the security mode is set is discarded. However, when the used master is discarded from the normal discharging box, the discharging unit is used. The number of discharged plates is detected by a discharged plate sensor provided at 26, and the operator is notified when the discharged plate is full. However, at this timing, the used master 5 is full in the discharge box 1, and therefore, when the used master 5 is discarded via the master discharging means 4, the number of used masters 5 is too large. There is a possibility that a problem that the used master 5 is clogged with the master discharging means 4 may occur. Therefore, as a modified example of the third embodiment, when the security mode is set, it is detected whether or not there is a used master 5 in the discharge box 1 by the discharge sensor, and the used master in the discharge box 1 is detected. If there is 5, the display means 64 may display a display prompting the operator to immediately discard it. A flowchart of this operation is shown in FIG. 11, and an example of display on the display means 64 is shown in FIG. With this configuration, only the used master 5 that requires confidentiality exists in the discharge box 1, so that the used master 5 that requires confidentiality can be discarded with certainty.

  In the third embodiment, the used master is damaged when the master made after the security mode is set is discarded. However, as the fourth embodiment, when the stencil printing apparatus 22 is in a standby state, After it is confirmed that the used master 5 is present in the discharge box 1, the elapsed time from the previous security mode plate making operation is measured by a timer (not shown) provided in the apparatus main body 29, and the previous security mode is set. 10 may be displayed on the display device 64 to discard the master in the discharge box 1 after a predetermined time has elapsed since the set master was made. This predetermined time can be arbitrarily set in the display device 64. FIG. 13 shows a flowchart of this operation, and FIG. 14 shows an example of setting a predetermined time. With this configuration, it is possible to manage that there is a used master 5 requiring confidentiality in the discharge box 1 and to adjust the amount of the used master 5 in the discharged box 1 by adjusting a predetermined time, and used confidential information that is used confidentially. The master 5 can be discarded while being reliably damaged.

  As a modification of the fourth embodiment, after it is confirmed that the used master 5 exists in the plate release box 1 after the security mode is set, the elapsed time from the previous plate making operation is stored in the apparatus main body 29. It is good also as a structure which time-measures with the provided timer which is not shown in figure and displays the display shown in FIG. 12 on the display apparatus 64 in order to discard the master in the discharging box 1 with respect to an operator after predetermined time passes since the last plate-making operation | movement. . A flowchart of this operation is shown in FIG. With this configuration, it is possible to appropriately control the amount of the used master 5 existing in the discharge box 1, so that it is possible to prevent the used master 5 that requires confidentiality from becoming damaged due to the used master 5 being full.

  Next, as a fifth embodiment, after it is confirmed that the used master 5 exists in the stencil box 1 during the operation of the stencil printing apparatus 22, the number of times of plate making from the plate making operation in which the previous security mode was set (this In the embodiment, since the plate removal is performed simultaneously with the plate making, the number of plate discharges) is counted by a counter (not shown) provided in the apparatus main body 29, and a predetermined number of times have passed since the master set with the previous security mode was made. It is good also as a structure which performs the display shown in FIG. 10 on the display apparatus 64 so that an operator may discard the master in the discharge box 1 later. This predetermined number of times can be arbitrarily set in the display device 64. A flowchart of this operation is shown in FIG. 16, and an example of setting the predetermined number of times is shown in FIG. With this configuration, it is possible to manage that there is a used master 5 that requires confidentiality in the discharge box 1 and to adjust the amount of the used master 5 in the discharge box 1 by adjusting a predetermined number of times, and thus used that requires confidentiality. The master 5 can be discarded while being reliably damaged.

  As a modified example of the fifth embodiment, after it is confirmed that the used master 5 is present in the discharge box 1 after the security mode is set, the used master 5 in the previous discharge box 1 is discarded. Is counted by a counter (not shown) provided in the apparatus main body 29 and displayed to the operator to discard the master in the discharge box 1 after a predetermined number of times have elapsed since the last disposal of the used master 5. It is good also as a structure which performs the display shown in FIG. A flowchart of this operation is shown in FIG. With this configuration, it is possible to appropriately control the amount of the used master 5 existing in the discharge box 1, so that it is possible to prevent the used master 5 that requires confidentiality from becoming damaged due to the used master 5 being full.
