[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a reproducing apparatus that makes a recording medium reusable by peeling off a recording material that forms the image from a recording medium on which an image is formed on an image recording surface by an electrophotographic method or an inkjet method.
[0002]
[Prior art]
  2. Description of the Related Art Conventionally, a technique for reusing a recording medium such as paper or film having an image formed on a recording surface by removing the recording material from the recording surface is known.
  For example, using a recording medium on which a thermoplastic elastomer film is formed, the recording surface on which an image is formed on the recording medium is subjected to thermocompression bonding at a temperature higher than the melting point of the thermoplastic resin used for the thermoplastic elastomer. There is a type in which the thermoplastic resin is melted to loosen the holding force of the recording material by being pressed against the roller, and the recording material is attached to the thermocompression pressing roller (see, for example, Patent Document 1).
[0003]
  However, in such a configuration in which the film forming the recording surface is heated and melted, the recording material is likely to be infiltrated into the film, and it is difficult to completely remove the recording material, so the number of rewrites is reduced. There is a problem that it ends up.
  On the other hand, there is also a type that uses a removing means having a tip where two planes intersect and moves the tip while being brought into pressure contact with the recording medium to peel off the recording material (for example, Patent Document 2). reference.). In this configuration, it is possible to completely remove the recording material, and it is not necessary to provide a means for heating the recording medium, which is advantageous in terms of cost and space.

[Problems to be solved by the invention]
  However, in the configuration in which the recording material is peeled off by the removing means, if the force with which the tip of the removing means comes into contact with the recording medium is weak, the recording material is left behind. On the contrary, if the contact force is strong, the recording medium is damaged. Therefore, a very high accuracy is required for the mounting position of the removing means with respect to the recording medium. For this reason, parts must be designed and assembled with extremely high dimensional accuracy, which is difficult to realize.
[0007]
  The present invention has been made in view of these problems, and provides a recording medium reproducing apparatus capable of effectively peeling a recording material without requiring extremely high dimensional accuracy for designing and assembling parts. The purpose is to do.
[0008]
[Means for Solving the Problems and Effects of the Invention]
  In the recording medium reproducing apparatus according to claim 1, which is made to achieve the above object, an edge member having an edge portion which is an intersection line of two surfaces is provided, and a peeling means is provided on the edge member. The recording material on the recording surface is peeled off by changing the relative position of the edge portion and the recording surface along the recording surface with the edge portion pressed against the recording surface of the recording medium. And in particular, this reproducing apparatus is an adjustment means that enables adjustment of the mounting position of the edge member.A cleaning member that is impregnated with a non-volatile liquid and wipes off the recording material adhering to the edge member or the recording medium;It has.
[0009]
  According to the recording medium reproducing apparatus of the first aspect as described above, the adjustment is made so that the edge portion is pressed against the recording surface in an optimum state even if there is a slight error in the mounting position of the edge member. Therefore, the recording material on the recording surface can be effectively removed without designing or assembling the parts with extremely high dimensional accuracy.Further, since the cleaning member is always moistened by the non-volatile liquid, it is possible to prevent the recording material wiped off from being scattered.
[0010]
  Here, the adjusting means may be configured as in claim 2 or claim 3, for example.
  That is, in the recording medium reproducing apparatus according to the second aspect, the adjusting means is configured to change the attachment position of the edge member by rotating the member that can be rotated. According to this configuration, the adjustment of the attachment position of the edge member can be easily performed by a rotating operation.
[0011]
  In the recording medium reproducing apparatus according to claim 3, the adjusting means includes a gripping means for gripping the edge member, and the gripping means sandwiches a spacer between the gripping means and the edge member. It is configured to be able to. According to this configuration, the attachment position of the edge member can be accurately adjusted by adjustment based on the presence or absence of a spacer, adjustment using a spacer having a different thickness, or the like.
[0012]
  Next, in the recording medium reproducing apparatus according to the fourth aspect, the adjusting means is configured to be able to adjust the attachment position of the edge member in at least one direction. For this reason, for example, as the adjustable direction is closer to the direction perpendicular to the recording surface of the recording medium, the pressure with which the edge portion of the edge member is pressed against the recording surface of the recording medium can be greatly adjusted. As the adjustable direction is closer to the surface direction of the recording surface of the recording medium, the pressure with which the edge portion of the edge member is pressed against the recording surface of the recording medium can be finely adjusted. Moreover, if it is comprised so that it can adjust in two or more directions, the freedom degree of the adjustment position of an edge part can be made high.
[0013]
  Next, a recording medium reproducing apparatus according to a fifth aspect includes a plurality of edge members, and the plurality of edge members are arranged in parallel so that the edge portions are aligned. According to this configuration, the recording material can be more effectively removed.
  That is, for example, in the configuration in which the recording material on the recording surface is peeled off by one edge member, the edge member becomes larger and the edge portion is likely to be warped, and the edge member itself can be manufactured with high accuracy. It becomes difficult. For this reason, although it is preferable to divide into a plurality of edge members, in this case, it is necessary to provide the edge members at positions separated from each other (for example, in a staggered manner) in order to reduce the influence due to the error in the mounting position of each edge member. There is. As a result, the edge portion of the edge member is locally pressed against the recording surface, and the recording medium is likely to be undulated, which may cause the recording material to remain peeled off or damage the recording surface. It becomes a cause.
[0014]
  On the other hand, in the recording medium reproducing apparatus according to the fifth aspect, since the error of the attachment position of each edge member can be adjusted by the adjusting means, a plurality of edge members can be arranged in parallel. For this reason, it is possible to prevent the recording medium from being wavy, and the recording material can be more effectively removed by the plurality of edge members.
[0015]
  Next, in the recording medium reproducing apparatus according to claim 6, the peeling means presses the recording medium against the edge member by the elastic body, so that the edge portion of the edge member is pressed against the recording surface of the recording medium. It is configured to be According to this configuration, the force with which the edge portion of the edge member is pressed against the recording surface of the recording medium can be made uniform by the elastic body. In general, the elastic body itself is not suitable for high-precision positioning because of its low dimensional accuracy. However, in this reproducing apparatus, the mounting position of the edge member can be adjusted by the adjusting means. It can also compensate for body-specific defects.
[0016]
  By the way, in the configuration in which the recording medium is pressed against the edge member by the elastic body, it is conceivable that the periphery of the recording surface is likely to be lifted by sinking the pressing position of the edge portion on the recording surface to the elastic body side.
  Therefore, in the recording medium reproducing apparatus according to claim 7, when the relative position between the edge portion and the recording surface is changed by the peeling means, at least the position where the edge portion on the recording surface is about to move is defined as the elastic body. There is a restraining means to hold it down. According to this configuration, the edge portion and the recording surface can always be brought into contact with each other in an optimal direction by suppressing the lift of the position where the recording material is to be peeled off on the recording surface, so that the peeling performance of the recording material is stable. Can be made.
[0017]
[0018]
  on the other handNon-volatile liquid, for example, claims8As described above, silicone oil may be used. This is because silicone oil is safe and easy to handle because it is harmless even if it adheres to the human body.
[0019]

  Embodiments to which the present invention is applied will be described below with reference to the drawings.
  FIG. 1 is a schematic configuration diagram of a recording medium playback apparatus (hereinafter simply referred to as a playback apparatus) 10 according to an embodiment.
[0020]
  The reproducing apparatus 10 comes into contact with the rollers 20 and 22 that convey the A4 size sheet-like recording medium 60 and the recording surface 60a of the recording medium 60 that is conveyed, and peels the recording material K on the recording surface 60a. A peeling device 30 having a rectangular parallelepiped plate-like blade 32, and a pressing device 50 that presses the conveyed recording medium 60 toward the blade 32 by a rubber plate 56 that receives a pressing force of a spring 54 attached to a support base 52. It has. Although not shown, the pressing device 50 operates in a state where the recording medium 60 is not conveyed between the blade 32 and the rubber plate 56, and the rubber plate 56 is moved from the blade 32 against the pressing force of the spring 54. A release mechanism is provided for holding at a distant position.
[0021]
  FIG. 2 is an explanatory view of the appearance of the peeling device 30 as viewed from the direction indicated by the arrow A in FIG. As shown in FIG. 2, three strippers 30 are arranged in parallel in a direction perpendicular to the conveyance direction of the recording medium 60 and along the recording surface 60a (hereinafter referred to as the width direction of the recording medium 60). Yes.
[0022]
  FIG. 3 is a cross-sectional view of the peeling device 30 cut along a plane perpendicular to the width direction of the recording medium 60.
  As shown in FIG. 3, the peeling device 30 includes the blade 32, a first fixing member 34 and a second fixing member 36 that sandwich and hold the blade 32 from both sides in the thickness direction, and the first fixing member 34 and the blade. 32, a fixing screw 38 that is screwed into the second fixing member 36 and an adjustment screw 40 that is screwed into the second fixing member 36 in a direction perpendicular to the fixing screw 38.
[0023]
  The first fixing member 34 is a rectangular parallelepiped plate. The first fixing member 34 is provided with a through hole 34c through which a fixing screw 38 passes from a gripping surface 34a for gripping the blade 32 to a surface 34b on the opposite side. The first fixing member 34 is fixed at a certain position in the reproducing apparatus 10.
[0024]
  The second fixing member 36 is a plate having an L-shaped cross section. The second fixing member 36 is provided with a screw hole 36c into which a fixing screw 38 is screwed from a gripping surface 36a for gripping the blade 32 to a surface 36b on the opposite side. A screw hole 36f into which the adjusting screw 40 is screwed is provided from a surface 36d perpendicular to the gripping surface 36a to a surface 36e on the opposite side. The adjustment screw 40 is formed with a recess 40a for inserting a hexagon wrench.
[0025]
  On the other hand, the blade 32 is provided with a through hole 32a through which the fixing screw 38 passes in the thickness direction. The through-hole 32a has a long hole shape in which the axial direction of the adjustment screw 40 (hereinafter referred to as the first adjustment direction) is the longitudinal direction, and the blade can be used even when the fixing screw 38 is passed through the through-hole 32a. The position 32 can be changed along the first adjustment direction.
[0026]
  Further, an intersection line between two surfaces 32 b and 32 c orthogonal to each other in the blade 32 forms an edge portion 32 d that contacts the recording surface 60 a of the recording medium 60. In addition, it is preferable that the surface roughness of these two surfaces 32b and 32c is 20 micrometers or less. This is because the releasability of the recording material K can be remarkably improved.
[0027]
  Here, the material of the blade 32 is preferably a material having the hardness and durability necessary for peeling the recording material K from the recording surface 60a of the recording medium 60, such as zirconia or tungsten carbide. Ceramic materials, metallic materials such as stainless steel and titanium alloy, plastic materials such as polycarbonate, ABS resin, polyphenylene sulfide, polyether ether ketone, and polyether sulfone, and other materials such as glass and diamond can be used.
[0028]
  The blade 32 is clamped by the fixing screw 38 while being sandwiched between the first fixing member 34 and the second fixing member 36, so that the position of the reproducing apparatus 10 is fixed. Here, the attachment position of the blade 32 can be adjusted by the following method.
[0029]
  That is, when adjusting the attachment position of the blade 32 along the first adjustment direction, the adjustment screw 40 is rotated with the fixing screw 38 slightly loosened. For example, in order to adjust the attachment position of the blade 32 to the side where the contact pressure of the edge portion 32d with respect to the recording surface 60a increases, the adjustment screw 40 may be rotated so as to move toward the blade 32 side. Conversely, in order to adjust the contact pressure to be reduced, the adjustment screw 40 is rotated so as to move to the side opposite to the blade 32, and the position of the blade 32 is brought into contact with the adjustment screw 40. To match. In particular, in the present reproducing apparatus 10, as shown in FIG. 2, since the adjusting screws 40 are provided on both sides in the longitudinal direction of each peeling device 30, it is possible to adjust the inclination of the blade 32 in the longitudinal direction. The entire edge portion 32d can be adjusted to contact the recording surface 60a with a uniform contact pressure.
[0030]
  Further, when the attachment position of the blade 32 is adjusted along the thickness direction (hereinafter referred to as a second adjustment direction), as shown in FIG. 4, between the first fixing member 34 and the blade 32, A plate-like spacer 70 provided with a through hole 70a through which the fixing screw 38 passes is sandwiched. In the reproducing apparatus 10, since the position of the first fixing member 34 in the apparatus 10 is fixed, the attachment position of the blade 32 is set to the contact position of the edge portion 32d with the recording surface 60a by sandwiching the spacer 70. The pressure is adjusted to increase.
[0031]
  As described above, in the peeling device 30, the attachment position of the blade 32 can be adjusted in two perpendicular directions of the first adjustment direction and the second adjustment direction, and the adjustment direction is perpendicular to the recording surface 60 a of the recording medium 60. The closer the direction is, the greater the influence on the contact pressure. For example, when the second adjustment direction is closer to the direction perpendicular to the recording surface 60 a than the first adjustment direction, the adjustment by the spacer 70 has a greater influence on the contact pressure than the adjustment by the adjustment screw 40.
[0032]
  Further, by adjusting in the first adjustment direction and the second adjustment direction, it is possible to adjust the position of the edge portion 32d of the blade 32 along the conveyance direction of the recording medium 60 and the direction perpendicular to the recording surface 60a. Become. For this reason, it can also align so that the edge part 32d of the adjacent braid | blade 32 may be located in a straight line.
[0033]
  On the other hand, although not shown in FIG. 1, the reproducing apparatus 10 has the recording medium 60 positioned at positions corresponding to the upstream side and the downstream side of the blade 32 along the conveyance direction of the recording medium 60 as shown in FIG. Holding members 80 and 82 for holding the recording surface 60a to the rubber plate 56 side in the entire width direction are provided. The holding members 80 and 82 prevent the recording medium 60 from being lifted by the recording medium 60 being pressed against the rubber plate 56 side by the edge portion 32d of the blade 32 and sinking.
[0034]
  Furthermore, as shown in FIG. 6, the reproducing apparatus 10 includes a first cleaning member 90 that wipes off the recording material K attached to the blade 32, and a second cleaning member 90 that wipes off the recording material K attached to the recording surface 60a of the recording medium 60. And a cleaning member 92.
  When the release mechanism of the pressing device 50 is operated and the rubber plate 56 is held at a position away from the blade 32, the first cleaning member 90 is pressed against the edge portion 32d of the blade 32 by a driving device (not shown). And moved so as to reciprocate along the longitudinal direction of the edge portion 32d.
[0035]
  Further, the second cleaning member 92 is provided at a position corresponding to the upstream side of the rollers 20 and 22 along the conveyance direction of the recording medium 60, and contacts the recording surface 60 a in the entire width direction of the recording medium 60.
  Here, as the first cleaning member 90 and the second cleaning member 92, for example, felt, cloth, nonwoven fabric, paper, sponge, brush, or the like impregnated with a non-volatile liquid such as silicone oil is used. preferable. For example, when the recording material K is toner, the recording material K is electrostatically charged by being peeled off from the recording medium 60. Therefore, with the dry cleaning member, the recording material K once wiped is scattered, and the blade 32 or the recording material is recorded. This is because it tends to reattach to the medium 60.
[0036]
  On the other hand, as shown in FIG. 7, the recording medium 60 used in the reproducing apparatus 10 is obtained by applying the adhesive 64 to both surfaces of the sheet-like base material 62 and bonding the top sheets 66 and 66 together. Is.
  Here, the base material 62 is preferably one having a high flexural modulus in order to give tension as the recording medium 60. For example, in addition to paper and nonwoven fabric, polyethylene terephthalate, polybutylene terephthalate, foamed polypropylene, Plastic sheets such as polycarbonate, nylon, polyphenylene sulfide, polyether sulfone, and polyether ether ketone can be used.
[0037]
  Further, as the material of the surface sheet 66, a material excellent in fixing property and peelability of the recording material K is preferable. For example, polypropylene, polyethylene, polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinyl fluoride, polyvinylidene fluoride. Ride, polymethylpentene, etc., mixtures and copolymers containing these, other tetrafluoroethylene-perfluorovinyl ether copolymers, tetrafluoroethylene-hexafluoropropylene copolymers, tetrafluoroethylene-ethylene A copolymer or the like can be used.
[0038]
  Next, the operation of the playback apparatus 10 will be described.
  When the recording medium 60 is conveyed between the blade 32 and the rubber plate 56, the recording medium 60 is pressed against the blade 32 by the pressing device 50. Thereby, the recording medium 60 is conveyed in a state where the edge portion 32d of the blade 32 is pressed against the recording surface 60a of the recording medium 60, and the recording material K on the recording surface 60a is peeled off by the edge portion 32d.
[0039]
  Then, the recording surface 60 a that has passed through the edge portion 32 d contacts the second cleaning member 92. Thereby, even if the recording material K once peeled off from the recording surface 60a by the blade 32 is reattached to the recording surface 60a, it is wiped off by the second cleaning member 92.
[0040]
  When the recording medium 60 is not conveyed between the blade 32 and the rubber plate 56, the rubber plate 56 is held at a position away from the blade 32, and the first cleaning member 90 is pressed against the edge portion 32 d of the blade 32. It is applied and moved along the edge portion 32d. As a result, the recording material K peeled off from the recording surface 60 a and attached to the blade 32 is wiped off by the first cleaning member 90.
[Example]
  Hereinafter, the contents of the test conducted by the inventor on the playback apparatus 10 and the results thereof will be described.
[0041]
  The recording medium 60 used in this test is a white terephthalate film (manufactured by Toray Industries, Inc.) having a thickness of 50 μm containing titanium oxide, and a pressure sensitive adhesive 64 having a thickness of 3 μm is applied on both sides. Then, a polymethylpentene film (manufactured by Mitsui Chemicals, Inc.) having a thickness of 25 μm was prepared as a surface sheet 66, 66 by bonding. When printing was performed on the recording medium 60 using a laser printer HL-1440 manufactured by Brother Industries, Ltd., good printing was performed without causing curling on the recording medium 60. Further, the recording medium 60 after printing was subjected to a five-way rubbing test using a linen cloth with a load of 300 g using a friction fastness tester, but there was no peeling of the recording material (toner in this test) K. It was confirmed that good fixability was obtained.
[0042]
  Example 1
  First, as Example 1, the playback device 10 was set under the following conditions.
  That is, as the blade 32, a blade made of zirconia having a width in the longitudinal direction of 80 mm and an angle between the two flat surfaces 32b and 32c forming the edge portion 32d of 90 ° was used. Then, the three blades 32 were juxtaposed in a state where the edge portions 32d were arranged in a straight line and the gap between the adjacent blades 32, 32 was 100 μm or less. Further, the blade 32 was provided in an orientation in which the rake angle (angle formed by the blade surface where the recording medium and the recording material first contact) is 90 °. On the other hand, the rubber plate 56 is made of EPT rubber having a rubber hardness of 65 °, and a pressing force of 30 N is applied by the spring 54.
[0043]
  Then, when a test for peeling the recording material K from the recording medium 60 was performed using this reproducing apparatus 10, the recording material K near the center of the recording medium 60 in the width direction could not be peeled. For this reason, the mounting position of the central blade 32 of the three blades 32 was finely adjusted by inserting a 50 μm SUS plate as the spacer 70, and the test was performed again. . Further, the recording surface 60a was not damaged.
[0044]
  (Example 2)
  Next, in the second embodiment, in the reproducing apparatus 10, the blade 32 having an angle of 60 ° formed by the two planes 32b and 32c forming the edge portion 32d of the blade 32 is used. The other conditions were set to be the same as in Example 1 above.
[0045]
  Then, when a test for peeling the recording material K from the recording medium 60 was performed using the reproducing apparatus 10, the recording material K was peeled off, but the recording medium 60 was scratched near both ends in the width direction. For this reason, as for the two blades 32 at both ends of the three blades 32, the outer adjustment screw 40 was rotated away from the blade 32 by about 20 μm, the mounting position was adjusted, and the test was performed again. The recording surface 60a is no longer scratched. In addition, there was no remaining peeling of the recording material K.
[0046]
  (Example 3)
  Next, as Example 3, when the reproducing apparatus 10 was set to the same conditions as in Example 1 and the wiping operation by the first cleaning member 90 was not performed, a plurality of recording media 60 were repeatedly tested. In the fifth recording medium 60, the recording material K once peeled is sandwiched between the recording surface 60a and the edge portion 32d, and as a result, the recording material K is left behind. For this reason, the felt impregnated with silicone oil was used as the first cleaning member 90 to perform the wiping operation for wiping the edge portion 32d of the blade 32, and as a result of performing the test again, the recording material K was not left unseparated. . Further, the recording surface 60a was not damaged.
[0047]
  (Comparative example)
  On the other hand, as a comparative example, the same test as in Example 3 was performed, and instead of using the felt impregnated with silicone oil in Example 3 as the first cleaning member 90, a felt not impregnated with silicone oil was used. The wiping operation was performed. As a result, the recording material K having an electrostatic charge was scattered and reattached to the blade 32 and the rubber plate 56, and the recording material K was left behind in the test after the wiping operation.
[0048]
  In the reproducing apparatus 10 of this embodiment, the blade 32 corresponds to an edge member, and the rollers 20 and 22 and the pressing device 50 correspond to a peeling unit. Further, the first fixing member 34, the second fixing member 36, the fixing screw 38, and the adjusting screw 40 correspond to the adjusting means, and the first fixing member 34 and the second fixing member 36 correspond to the gripping means. Further, the rubber plate 56 corresponds to an elastic body, and the holding members 80 and 82 correspond to holding means.
[0049]
  As described above, according to the reproducing apparatus 10 of the present embodiment, it is possible to easily adjust the mounting position of the blade 32 to the optimum position without designing and assembling the parts with extremely high dimensional accuracy. The recording material K on the recording surface 60a can be effectively removed. In particular, in the adjustment with the adjustment screw 40, the amount of movement in the axial direction with respect to the rotation amount of the adjustment screw 40 is small, so that fine adjustment can be easily performed. The amount of adjustment can be determined accurately.
[0050]
  Moreover, since each blade 32 can be reduced in size by using a plurality of blades 32, the edge portion 32d can be prevented from warping and the peeling performance can be improved. In addition, since the blades 32 are arranged side by side so that the edge portions 32d are aligned, it is possible to prevent the recording medium 60 from being swelled.
[0051]
  Furthermore, the configuration in which the recording medium 60 is pressed against the edge portion 32d by the rubber plate 56 can reduce variations in the contact pressure of the edge portion 32d with respect to the recording surface 60a. In particular, since the mounting position of the blade 32 can be adjusted, even if the dimensional accuracy of the rubber plate 56 itself is poor, it is possible to adjust the rubber plate 56 to an optimal position. Further, since the rubber plate 56 is supported by the spring 54, the vibration generated when the recording material K is peeled off by the blade 32 is absorbed, and the peeling performance can be stabilized.
[0052]
  On the other hand, since the recording surface 60a can always be brought into contact with the blade 32 at a constant angle by the configuration in which the lifting of the recording medium 60 is suppressed by the suppressing members 80 and 82, the peeling performance can be stabilized.
  As mentioned above, although one Embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form.
[0053]
  For example, the recording medium 60 is not limited to one in which the surface sheets 66 and 66 are bonded to both surfaces of the base material 62 using the adhesive 64, and a surface layer that can peel the recording material K on both surfaces of the base material 62. A material coated with a material (hereinafter referred to as a surface agent) may be used. Here, as the surface agent, for example, a silicone-based, acrylic-based, fluorine-based, or melamine-based coating agent, or a polymer obtained by mixing or deforming these can be used.
[0054]
  Moreover, the structure which enables adjustment of the attachment position of the braid | blade 32 is not restricted to the structure of the peeling device 30 of the said embodiment.
  For example, in the peeling device 100 shown in FIG. 8A, the blade 32 is gripped by the plate-shaped first fixing member 102 having an L-shaped cross section and the plate-shaped second fixing member 104 having a rectangular parallelepiped shape. Similarly to the peeling device 30 (FIG. 3) of the above embodiment, the fixing screw 38 passes through the through hole 102a provided in the first fixing member 102 and the through hole 32a of the blade 32, and the second fixing member 104. Is screwed into a screw hole 104a provided in the. And in this peeling device 100, the expansion-contraction mechanism 106 which the rod-shaped member 106b expands-contracts in response to rotation operation of the rotation knob 106a is attached to the 1st fixing member 102, and also the 1st fixing member 102 and the 2nd fixing Between the member 104, two triangular members 108 and 110 having a right-angled isosceles triangle are provided so as to overlap each other so that the cross-section is a square.
[0055]
  Then, as shown in FIG. 8B, when the rotation operation of the rotary knob 106a is performed and the rod-shaped member 106b extends toward the triangular member 108, the triangular member 108 is moved by being pushed by the rod-shaped member 106b. Accordingly, the triangular member 110 slides toward the blade 32 and the blade 32 moves along the first adjustment direction. For this reason, the attachment position of the blade 32 can be adjusted very easily.
[0056]
  On the other hand, in the reproducing apparatus 10 of the above-described embodiment, the recording material K is peeled off by bringing the recording medium 60 into contact with the fixed blade 32 while being conveyed. However, the present invention is not limited to this. It may be configured to change the position of the blade 32 itself.
