There are also concerns about flammability and toxicity caused by the solvent. In addition, after removing the recording material, a step of drying and removing the solvent soaked in the paper is required, the apparatus size is increased, and drying heat energy may be required. As a result, there is a concern about air pollution by dry exhaust gas. Further, once the paper treated with a solvent is dried, the quality of the paper after the reproduction such as paper undulation or fluffing on the surface may be deteriorated.

  Japanese Patent Application Laid-Open No. 7-199757 proposes a method of removing a recording material by pressing the blade against the recording material and scraping it.

  However, with the method of removing the blade by pressing it against the recording material and removing it, the recording blade is easily touched by the rigid blade and the recording paper, and the gap between the blade and the recording paper is adjusted. However, depending on the location where the recording paper is held, there may be a problem that the recording material remains unremoved on the recording paper.

  Japanese Patent Application Laid-Open No. 11-352850 discloses a method for removing a recording material by bringing a release member having a hardness equal to or lower than the release layer of the recording paper into contact with the recording material printed on the recording paper. .

  The above method is very excellent in that the recording material is not damaged because the recording material of the release layer of the recording paper is removed by a release member having a hardness equal to or lower than the release layer of the recording paper.

  However, in the method of removing the recording material by contacting the recording material with a peeling member having a hardness equal to or lower than the peeling layer of the recording paper, the recording paper is held by the surface because the recording paper and the peeling member are in contact with each other. It is predicted that the recording sheet and the peeling member are in contact with each other on the surface, and the wear of the peeling member is large and disadvantageous in running cost.

Here, the surface of the recording medium 74 on which the recording material 107 is thermally fixed to the release layer is the upper side of the recording medium 74 in the drawing.

  FIG. 4 is a diagram for explaining the step (1) in which the recording material removing device removes the recording material on the surface of the recording medium. The recording medium removing device 1 of the recording medium 74 shows a state in which the recording medium 74 is passed by the sixth drive motor 66 and the peeling member 18 is passed by the second drive motor 28 on the upper side. The roller 48 is rotated in a state where the recording medium 74 is fed by the fourth driving motor 44 driving the second driving belt 47 and rotating the first driving roller 42, and the second recording medium feeding roller. 56 also rotates in a state in which the recording medium 74 is fed by the fifth drive motor 52 driving the third drive belt 55 and rotating the second drive roller 50.

And the leading edge B of the recording medium 74 is detected by the fifth paper sensor 16.

  FIG. 6 is a diagram for explaining the step (3) in which the recording material removing device removes the recording material on the surface of the recording medium. The feeding / discharging plate 58 of the recording material removing apparatus 1 is driven upward by the sixth drive motor 66, and the peeling member 18 drives the second drive motor 28 by detecting the leading edge B of the recording medium 74 by the fifth paper sensor 16. In other words, a state in which the peeling member 18 is brought into contact with the upper surface of the recording medium 74 on the side, that is, on the support 17 and the recording material 107 can be removed, the first driving motor 24 is driven, the peeling member 18 is rotated, While the peeling member 18 is moved across the recording medium 74 on the support 17 by the three-drive motor 39 (see FIGS. 2 and 3 for the position of the peeling member 18), the recording material 107 starts to be removed from the recording medium 74. This state is repeated, and this operation is repeated to reciprocate. At this time, the recording medium 74 is transported by driving the fourth drive motor 44 and the fifth drive motor 52 (to the right in the figure), but the transport speed is the peeling member 18 even if the above-described reciprocation is performed. It is the conveyance speed which made the locus | trajectory overlap.

  FIG. 7 is a diagram for explaining a process (4) in which the recording material removing apparatus removes the recording material on the surface of the recording medium. The recording / removal plate 58 of the recording material removing apparatus 1 is in the upper side by the sixth drive motor 66 and the peeling member 18 is in the lower side, and the recording medium 74 removes the recording material 107 by the peeling member 18 while the fourth driving motor 44.

Thus, the second paper sensor 13 is in a state immediately after the trailing edge C of the recording medium 74 is detected.

  FIG. 9 is a diagram for explaining a step (6) in which the recording material removing apparatus removes the recording material on the surface of the recording medium. When the feeding / discharging plate 58 of the recording material removing apparatus 1 is on the upper side and the peeling member 18 detects the rear end C of the recording medium 74 with the second paper sensor 13, the second driving motor 28 is driven to support the lower side, that is, the support. A state where the peeling member 18 is brought into contact with the upper surface of the recording medium 74 conveyed onto the body 17 to remove the recording material 107 is shown, the first driving motor 24 is driven to rotate the peeling member 18, and a third drive A state in which the recording member 107 starts to be removed from the recording medium 74 while the peeling member 18 is moved across the recording medium 74 on the support 17 by the motor 39 (see FIGS. 2 and 3 for the position of the peeling member 18). This is reciprocated. At this time, the recording medium 74 is conveyed by driving of the fourth drive motor 44 and the fifth drive motor 52 (to the left in the figure). It is the conveyance speed which made the locus | trajectory overlap.

  FIG. 10 is a diagram for explaining the step (7) in which the recording material removing apparatus removes the recording material on the surface of the recording medium. The recording material 107 can be removed by bringing the peeling member 18 into contact with the upper surface of the recording medium 74 conveyed onto the support 17, that is, the upper side of the feeding / discharging plate 58 of the recording material removing apparatus 1 and the lower side of the peeling member 18. The recording medium 74 is conveyed while driving the fourth drive motor 44 and the fifth drive motor 52 to remove the recording material 107 from the recording medium 74, and the rear end C of the recording medium 74 is connected to the first paper sensor 8. Is the state detected.

  FIG. 11 is a diagram for explaining the step (8) in which the recording material removing apparatus removes the recording material on the surface of the recording medium. In the recording material removing apparatus 1, when the first paper sensor 8 detects the trailing end C of the recording medium 74, the feeding / discharging plate 58 of the recording material removing apparatus 1 is moved downward by the sixth drive motor 66, that is, the paper discharge tray 11. In this state, the separation member 18 is on the lower side and shows a state in which the operation of removing the recording material 107 from the recording medium 74 is continued.

  FIG. 12 is a diagram for explaining the step (9) in which the recording material removing apparatus removes the recording material on the surface of the recording medium. The state in which the operation of removing the recording material 107 from the recording medium 74 is continued while the feeding / discharging plate 58 of the recording material removing apparatus 1 is on the lower side, that is, on the paper ejection tray 11 side, and the peeling member 18 is on the lower side. 11 shows a state immediately before the conveyance of the recording medium 74 is completed. Thereafter, the driving of the fourth drive motor 44 and the fifth drive motor 52 is stopped, the feed / discharge plate 58 is raised to the upper side, that is, the first guide plate 10 side by the sixth drive motor 66, and the series of operations is completed. The recording medium 74 from which the recording material 107 thermally fixed to the release layer of the recording medium 74 has been removed from the entire surface through the steps up to here can be obtained.

  Next, the configuration of the first to fifth paper sensors 8, 13, 14, 15, 16 will be described with reference to FIG. FIG. 13 is a schematic view of an optical sensor using LEDs used in the present invention. The light-emitting element 68 and the light-receiving element 69 are paired. When the recording medium 74 is between the light-emitting element 68 and the light-receiving element 69, that is, when the light is blocked, the light is transmitted. The time is set to be OFF. Under this condition, the drive motor is controlled sequentially by a program, but the description is omitted here.

  The configuration of the peeling member sensor 41 is the same as that of the optical sensor using the LED shown in FIG. 13, but the peeling member 18 is provided between the light emitting element 68 and the light receiving element 69, so The interval is wide. When the peeling member 18 is between the light emitting element 68 and the light receiving element 69, that is, when the light is blocked, it is set to be OFF, and when it is not present, that is, when the light is transmitted, it is set to be ON. As a result, when the peeling member 18 is worn and the light receiving element 69 detects the light of the light emitting element 68, a predetermined stop action is taken and a warning display for replacing the peeling member 18 is issued.

  Next, a situation in which the peeling member 18 removes the recording material 107 from the recording medium 74 will be described with reference to FIG.

  FIG. 14A is an explanatory diagram viewed from the side of the state in which the peeling member removes the recording material from the recording medium. The peeling member 18 made of an eraser has a cylindrical shape (see FIG. 14B), and the cylindrical surface 78 is in contact with the surface of the recording medium 74 conveyed on the support 17 in the state of tangent A. The recording material 107 is removed while rotating by the driving force of the first drive motor 24 around the rotation shaft 22. The recording material 107 is removed in a direction crossing the recording medium 74. Further, since the eraser of the eraser entrains the recording material 107, scattering of the recording material 107 is prevented. Further, since the cylindrical surface 78 of the peeling member 18 is in contact with the surface of the recording medium 74 in the state of the tangent A, wear and frictional resistance are minimized. The driving force of the first drive motor 24 is transmitted to the rotating shaft by the gear box 23.

FIG. 14B is an explanatory diagram viewed from the front side where the peeling member removes the recording material from the recording medium. The thickness of the peeling member 18 having a cylindrical shape is a width for removing the recording material 107 from the recording medium 74. Then, the first driving motor 24 is driven to rotate the peeling member 18, and the third driving motor 39 moves the peeling member 18 across the recording medium 74 on the support 17 (see FIGS. 2 and 3). ) The recording material 107 is removed from the recording medium 74. Furthermore, this is reciprocated. At this time, the recording medium 74 is transported by the drive of the fourth drive motor 44 and the fifth drive motor 52 (see FIGS. 6 and 9). It is the conveyance speed which the locus | trajectory of the member 18 was made to overlap. In this way, the recording material 107 thermally fixed to the release layer of the recording medium 74 is removed.

In a state where it can be removed, the first driving motor 24 is driven to rotate the peeling member 18, and the third driving motor 39 moves the peeling member 18 across the recording medium 74 on the support 17 (the peeling member). 18 indicates a state in which the removal of the recording material 107 from the recording medium 74 has begun to resume. At this time, the recording medium 74 is stopped because the driving of the fourth drive motor 44 and the fifth drive motor 52 is stopped. Then, when the peeling member 18 returns to the side where the movement starts from the opposite side, the peeling member 18 is raised upward by driving the second drive motor 28, and the fourth drive motor 44 and the fifth drive motor 52 are driven. The conveyance of the recording medium 74 (to the right side in the figure) is started. In addition, it is detected by the limit switch (not shown) that the peeling member 18 returned to the side which started the movement from the opposite side. This is repeated until FIG. 7 of the first embodiment becomes FIG. According to this method, the burden on the fourth drive motor 44 that drives the first recording medium feed roller 48 and the fifth drive motor 52 that drives the second recording medium feed roller 56 can be reduced.

  Next, a description will be given based on FIGS. FIG. 18 is a diagram for explaining a process (4) in which the recording material removing apparatus removes the recording material on the surface of the recording medium by another method. The process from FIG. 18 is a post-process from FIG. 8 shown in the first embodiment. In FIG. 8, the feeding / discharging plate 58 of the recording material removing apparatus 1 is in the upper side by the sixth driving motor 66, the peeling member 18 is in the upper side by the second driving motor 28, and the recording medium 74 is in the fourth driving motor 44 and the fifth driving motor. It is conveyed by the drive of the drive motor 52 (to the left in the figure), and after the rear end C of the recording medium 74 is detected by the second paper sensor 13, the recording medium removing device 1 of the recording medium in FIG. The feed / discharge plate 58 is driven upward by the sixth drive motor 66, and the peeling member 18 drives the second drive motor 28 by detecting the rear end C of the recording medium 74 by the second paper sensor 13. The peeling member 18 is brought into contact with the upper surface of the recording medium 74 on the body 17 so that the recording material 107 can be removed, the first driving motor 24 is driven to rotate the peeling member 18, and the third driving motor 39 support While the release member 18 is moved across the recording medium 74 on 17 (position of the release member 18 see FIGS. 2 and 3) shows a state in which began to remove the recording material 107 from the recording medium 74. At this time, the recording medium 74 is stopped because the driving of the fourth drive motor 44 and the fifth drive motor 52 is stopped. When the peeling member 18 reaches the side opposite to the side on which the movement starts, the second driving motor 28 drives the peeling member 18 upward to drive the fourth driving motor 44 and the fifth driving motor 52. Then, conveyance of the recording medium 74 (to the left side in the figure) is started. It is detected by a limit switch (not shown) that the peeling member 18 has arrived on the side opposite to the side on which the movement has started.

  FIG. 19 is a diagram for explaining a step (5) in which the recording material removing apparatus removes the recording material on the surface of the recording medium by another method. In FIG. 19, from the state where the peeling member 18 of FIG. 18 is raised and the fourth drive motor 44 and the fifth drive motor 52 are driven to start conveying the recording medium 74 (to the left side in the figure). A state in which the medium 74 is conveyed at a pitch slightly shorter than the thickness of the peeling member 18 is shown. Then, the remaining portions of the recording material 107 are prevented from being removed by overlapping the portions to be removed.

FIG. 20 is a diagram for explaining a step (6) in which the recording material removing apparatus removes the recording material on the surface of the recording medium by another method. In FIG. 20, the peeling member 18 second drive motor 28 is driven in the state of FIG. 19 to remove the recording material 107 by bringing the peeling member 18 into contact with the lower side, that is, the upper surface of the recording medium 74 on the support 17. In a ready state, the first driving motor 24 is driven to rotate the peeling member 18, and the third driving motor 39 moves the peeling member 18 across the recording medium 74 on the support 17 (the peeling member 18. 2 indicates the state in which the removal of the recording material 107 from the recording medium 74 has started to resume. At this time, the recording medium 74 is stopped because the driving of the fourth drive motor 44 and the fifth drive motor 52 is stopped. When the peeling member 18 arrives at the side where movement starts from the opposite side, the peeling member 18 is raised upward by the drive of the second drive motor 28, and the fourth drive motor 44 and the fifth drive motor 52 are driven to perform recording. The conveyance of the medium 74 (to the left side in the figure) is started. It is detected by a limit switch (not shown) that the peeling member 18 arrives at the side where movement has started from the opposite side. This is repeated until FIG. 12 of the first embodiment is reached. According to this method, the burden on the fourth drive motor 44 that drives the first recording medium feed roller 48 and the fifth drive motor 52 that drives the second recording medium feed roller 56 can be reduced. In this way, the recording material 107 thermally fixed to the release layer of the recording medium 74 is removed from the entire surface of the recording medium 74.
Example 3

In Example 3, returning to FIGS. 6 and 9, the pressing force applied to the recording medium 74 of the peeling member 18 is detected by the pressure sensor 19 disposed on the upper surface of the support 17 of the recording medium, and the value is determined. The operation for controlling to the specified value will be described. The pressing force applied to the recording medium 74 by the peeling member 18 is detected by the pressure sensor 19 via the recording medium 74, and if the detected value is smaller than the determined value, the second drive motor 28 is driven and determined. The pressure is increased until a predetermined value is reached, and if the detected value is larger than the determined value, the second drive motor 28 is driven and the pressure is reduced until the determined value is reached. To do. With this control, the recording material 107 can always be completely removed from the recording medium 74. In addition, this control prevents an increase in wear of the peeling member 18 and an increase in frictional resistance due to excessive pressurization, and prevents insufficient removal of the recording material 107 from the recording medium 74 due to insufficient pressurization. This control is preferably performed while the recording medium 74 is under the peeling member 18.
Example 4

  In the fourth embodiment, returning to FIGS. 6 and 9, an embodiment in which a heat source is used to assist the removal of the recording material 107 of the peeling member 18 will be described. A heater 20 for heating the support 17 is provided inside the support 17 that supports the recording medium 74, and a temperature sensor 21 for making the temperature of the heater 20 constant is provided on the support 17. When the recording medium 74 is conveyed on the support 17, the recording material 107 thermally fixed to the release layer of the recording medium 74 is softened or melted, so that the operation of removing the recording material 107 by the release member 18 is easy. become able to. At this time, if a heat-resistant member is used as a surrounding member, it is not affected by heat. In addition, this can be performed by utilizing the empty space of the support 17 that supports the recording medium 74 without adding extra space.

  As described above, in the recording material removing apparatus 1 for the recording medium 74 according to this embodiment, the peeling member 18 includes the cylindrical portion 77 and can be driven to rotate about the rotation shaft 22 of the cylindrical portion 77. When the cylindrical portion 77 of the peeling member 18 is rotating, the recording material 107 of the recording medium 74 is removed while pressing the peeling layer of the recording medium 74 so that the cylindrical surface 78 of the cylindrical portion 77 is tangent A. Therefore, unlike the case where the release layer of the recording medium 74 is pressed by the surface of the release member 18, it is pressed by the tangent line A, so that the wear of the release member 18 can be minimized.

  Further, the peeling member 18 includes at least a cylindrical portion 77 and can be driven to rotate about the rotation shaft 22 of the cylindrical portion 77. When the cylindrical portion 77 of the peeling member 18 is rotating, the cylindrical portion 77 is rotated. Since the recording material 107 of the recording medium 74 is removed while pressing the release layer of the recording medium 74 so that the cylindrical surface 78 of the recording medium 74 is tangent A, the release layer of the recording medium 74 is pressed by the surface of the release member 18. Since the pressing is performed at the tangent line A, the frictional resistance between the peeling member 18 and the peeling layer of the recording medium 74 can be minimized.

  Next, in the recording material removing apparatus 1, since the peeling member 18 is an eraser, it is possible to prevent the recording material 107 from being scattered by winding the removed recording material 107 into the scraped eraser. effective.

  Further, since the peeling member 18 is an eraser, there is an effect that the notation by a writing instrument such as a pencil written on the recording medium 74 can be removed.

  Next, in the recording material removing apparatus 1, the recording material 107 of the recording medium 74 is removed by adding a powder bed method microcapsule containing a solvent of ethyldiphenyl, diethyldiphenyl, or triethyldiphenyl to the peeling member 18. As a result, the recording medium 74 is not contaminated, and the recording material 107 can be provided with excellent removability.

  Furthermore, since the solvent used has a relatively high boiling point, it is excellent in stability over time as the peeling member 18 and has an effect that the odor during use can be alleviated as much as possible.

  Next, in the recording material removing apparatus 1, first and second recording medium feeding rollers 48 and 56 that transport the recording medium 74 before and after the peeling member 18, and the first or second recording medium below the peeling member 18. And a support member 17 that supports the recording medium 74 conveyed by the medium feed rollers 48 and 56, the peeling member 18 is provided with a cylindrical portion 77, and is driven to rotate about the rotation shaft 22 of the cylindrical portion 77. The first or second recording medium feed rollers 48 and 56 can be used for the release layer of the recording medium 74 that has been conveyed to the support 17 by the first or second recording medium feed rollers 48 and 56. The recording material 107 of the recording medium 74 is removed by pressing the cylindrical surface 78 of the cylindrical portion 77 so as to be tangent A while holding 74 and rotating the cylindrical portion 77 of the peeling member 18. , Record The body 74 is stably held, and there is no wasteful movement of the recording medium 74 by the peeling member 18, so that the problem of wrinkles of the recording medium 74 can be solved, and the peeling layer of the recording medium 74 is pressed against the surface of the peeling member 18. Unlike the above, since the contact area is minimized by pressing at the tangent A, there is an effect that the wear of the peeling member 18 can be minimized.

  Further, the first and second recording medium feed rollers 48 and 56 that transport the recording medium 74 before and after the peeling member 18, and the first or second recording medium feed rollers 48 and 56 below the peeling member 18. The peeling member 18 is provided with a cylindrical portion 77, and can be driven to rotate about the rotation shaft 22 of the cylindrical portion 77. The cylindrical portion 77 while holding the recording medium 74 with the first or second recording medium feeding rollers 48, 56 against the release layer of the recording medium 74 conveyed to the support 17 by the recording medium feeding rollers 48, 56. The recording material 107 of the recording medium 74 is removed by pressing the cylindrical surface 78 of the recording medium 74 so as to be tangent A and rotating the cylindrical portion 77 of the peeling member 18, so that the recording medium 74 is stably held. The Unlike the pressing movement of the recording medium 74 by the peeling member 18 and the pressing of the peeling layer of the recording medium 74 with the surface of the peeling member 18, the peeling member 18 and the recording medium 74 are pressed with the tangent line A. The frictional resistance with the release layer can be minimized, and the driving ability of the first drive motor 24 can be replaced with a small one, so that there is an effect that the problem of cost and downsizing of the apparatus can be dealt with.

  Next, in the recording material removing apparatus 1, the rotation direction of the cylindrical portion 77 of the peeling member 18 and the moving direction of the cylindrical portion 77 of the peeling member 18 intersect with the direction in which the recording medium 74 is fed. Scanning is performed while removing the recording material 107 of the stationary recording medium 74, and once the peeling member 18 is lifted, the recording medium 74 is transported a little shorter than the length of the cylindrical portion 77 of the peeling member 18, and the recording is stopped by the peeling member 18. Since the scanning method can be used while removing the recording material 107 of the medium 74, there is an effect that the recording material 107 can be removed reliably.

  Next, in the recording material removing apparatus 1, the recording medium feeding rollers 48 and 56 that function as recording medium feeding rollers function as the recording medium pressing rollers 48 and 56 when the peeling member 18 removes the recording material 107 of the recording medium 74. Thus, there is no need to newly provide a recording medium pressing roller, and there is an effect that the problem of cost and space can be improved extremely well.

  Next, in the recording material removing apparatus 1, since the cylindrical portion 77 of the peeling member 18 is shorter than the lengths of the first and second recording medium feed rollers 48 and 56, the friction of the cylindrical portion 77 of the peeling member 18 is reduced. The resistance can be made smaller than the frictional resistance of the first and second recording medium feed rollers 48 and 56. Further, when the recording medium 74 is conveyed while removing the recording material 107, the frictional resistance of the first and second recording medium feed rollers 48 and 56 is determined only by considering the length of the cylindrical portion 77 of the peeling member 18. Since there is no need to add a member for increasing the cost, the cost problem can be improved extremely well.

  Next, in the recording material removing apparatus 1, since the support 17 has a heat source that makes the temperature applied to the recording material 107 of the recording medium 74 equal to or higher than the glass transition temperature, the recording material 107 is softened or melted. Therefore, there is an effect that it can be easily removed from the recording medium 74 and a heat source is put in the support 17 so that no extra space is required.

  Next, in the recording material removing apparatus 1, the recording material 107 is removed from the recording medium 74 by the peeling member 18 so as to reciprocate the first and second recording medium feed rollers 48 and 56. Since the recording material 107 is removed from the entire surface, the recording material 107 at the front end B and the rear end C of the recording medium 74 that has been difficult to remove can be removed very easily.

  Next, in the recording material removing apparatus 1, a support body 17 that supports the recording medium 74 is provided below the peeling member 18, and the support body 17 is provided with a pressure sensor 19 on the surface side that receives the recording medium 74. 18 includes a cylindrical portion 77 and can be driven to rotate about the rotation axis 22 of the cylindrical portion 77. The cylindrical portion 77 of the peeling member 18 is rotated with respect to the peeling layer of the recording medium 74.
