JP 2008-110506 A

  The cutting apparatus includes a fixed blade having a cutting edge in a direction intersecting with the conveyance direction of the roll paper, and a rotating blade that rotatably contacts the cutting edge of the fixed blade at a predetermined angle. In such a configuration, the rotary blade has an angle with respect to the conveyance direction of the roll paper, and tries to bite toward the conveyance upstream side when cutting the roll paper. For this reason, the cutting device receives force from the roll paper in a direction in which the entire device including the fixed blade is shifted to the upstream side of the conveyance as the rotary blade moves in the cutting direction.

  Therefore, in order to smoothly lift and lower the cutting device while suppressing the load, a slight backlash (gap) is required for the lifting means to slide the cutting device smoothly. On the other hand, if the cutting operation is performed in a state where the cutting device is inclined toward the conveyance downstream side due to the presence of such play, the cutting device is pulled to the conveyance upstream side with the movement of the rotary blade. Therefore, the position of the cutting device in the conveyance direction may be displaced (or become unstable) during the cutting operation. Since the roll paper is cut along the cutting edge of the fixed blade, if the cutting device is displaced during the cutting operation, the cut line does not become a straight line, and the cut line may be bent at a position near the start of cutting.

  The present invention has been made in view of such technical problems. An object of the present invention is to provide a recording apparatus capable of reducing a load when moving up and down a cutting device for cutting continuous paper and making a cut line straight when cutting continuous paper. .

  The present invention has a linear fixed blade disposed in a direction intersecting the conveyance direction of continuous paper, and a rotary blade that rotatably contacts the fixed blade at a predetermined angle from the conveyance downstream side, A cutting device that cuts the continuous paper by moving the rotary blade along the fixed blade, and a lift for moving the cutting device between a cutting position where the continuous paper can be cut and a retreat position where the continuous paper is retracted upward And when the cutting device is moved to the cutting position by the elevating means, the cutting device is rotated to the upstream side of conveyance about a fulcrum extending in a direction intersecting the conveyance direction. Thus, the cutting device is brought into contact with a position regulating member on the upstream side of conveyance.

  ADVANTAGE OF THE INVENTION According to this invention, while reducing the load at the time of raising / lowering the cutting device for cut | disconnecting continuous paper, the recording device which can make the cut line at the time of cutting continuous paper into a straight line is provided.

Embodiments of the present invention will be specifically described below with reference to the drawings. Note that the same reference numerals denote the same or corresponding parts throughout the drawings.
[First Embodiment]
FIG. 1 is a longitudinal sectional view showing a state when a cutting device of a recording apparatus according to an embodiment is in a cutting position. FIG. 2 is a longitudinal sectional view showing a state when the cutting device of the recording apparatus of FIG. 1 is in the retracted position. The recording apparatus 1 can automatically switch both recording media of a predetermined size of cut paper and continuous roll paper. The roll paper 101 which is continuous paper is a recording medium made of a wound recording paper or a plastic sheet, and the cut paper 102 is a recording medium made of a recording paper or a plastic sheet cut to a certain size. As these continuous paper and cut paper, various materials can be used, and the material is not limited. The illustrated recording apparatus 1 exemplifies a case where the recording apparatus 1 is an inkjet recording apparatus that performs recording by discharging ink from a discharge port of the recording head 70 to a recording medium based on image information.

  First, with reference to FIG. 1, a series of operations from when a roll paper is fed to a recording apparatus and cut by a cutting apparatus will be described. The roll paper 101 which is continuous paper is conveyed to the conveyance roller 3 by a roll paper feed roller 2 comprising a pair of rollers as conveyance means. The conveyance roller 3 includes a pair of rollers as conveyance means, and conveys roll paper and cut paper to the image forming unit. The carriage 4 is equipped with a recording head 70 and is guided and supported so as to reciprocate along a carriage shaft 5 as a main scanning guide. The platen 6 guides and supports the recording medium from the back side in the image forming unit, and guarantees a gap between the recording head 70 and the recording medium. A pair of rotators including the paper discharge roller 7 and the spur 7a are transport means for guiding the recording medium transported through the image forming unit from the paper discharge port 71 to the paper discharge tray 9 outside the apparatus main body.

  A cutting device 8 is disposed between the paper discharge roller 7 and the paper discharge port 71. The cutting device 8 is for cutting the roll paper 101 into a predetermined size by the rotary blade 21 and the fixed blade 31. The recording apparatus 1 is moved up and down to move the cutting apparatus 8 up and down (drive up and down) between a cutting position along a conveyance path capable of cutting the continuous paper (roll paper) 101 and a retracted position retracted upward. Means 40 (FIG. 6) are provided. When recording an image on the roll paper 101, it is confirmed whether or not the cutting device 8 is arranged at the cutting position. If the cutting device 8 is not arranged at the cutting position, the roll paper 101 is moved down to the cutting position. To a state where it can be disconnected. Then, the roll paper 101 is conveyed to the conveyance roller 3 while being unwound by the roll paper feed roller 2. When the roll paper 101 reaches the nip of the transport roller 3, the roll paper feed roller 2 is in a state where the nip is opened. Next, the roll paper 101 is conveyed to the image forming unit by the conveyance roller 3.

  The recording apparatus 1 is provided with a control unit 90 including a controller having a CPU, a memory, an I / O circuit, and the like. The control means 90 controls the operation of the drive motor and various devices according to a control program stored in advance in the internal memory. Thus, the conveyance / recording operation of the recording medium (continuous paper and cut paper) is controlled, and the drive of the recording head 70 is controlled based on the image data, thereby recording an image on the recording medium. Moreover, the control means 90 controls operation | movement of the cutting device 8 and the raising / lowering means 40 (50). Further, the control means 90 controls the overall operation and timing of other recording apparatuses.

  In the image forming unit, when an image is formed by scanning for one line by the forward or backward movement of the carriage 4, the roll paper 101 is fed by the transport roller 3 in the direction of arrow A (transport direction) by a predetermined pitch. Therefore, the carriage 4 is moved again to form an image for the next line. By alternately repeating image formation for one line and paper feeding at a predetermined pitch, an image is recorded on the entire page. The recorded portion of the roll paper 101 is conveyed by a paper discharge roller 7 toward a paper discharge tray 9 outside the apparatus main body. When the recording of the predetermined range (one page) is completed, the roll paper 101 is conveyed to a predetermined cutting position by the conveying roller 3. The cutting device 8 is configured to cut the recording medium supported by the upper surface of the fixed blade 31 disposed on the lower side by the rotary blade 21 from the upper surface at the cutting position. When the roll paper 101 is conveyed to the cutting position, the roll paper 101 is sandwiched between the discharge roller 7 and the spur 7a. And the recorded roll paper 101 is cut | disconnected by the rotary blade 21 and the fixed blade 31 of the cutting device 8 in a cutting position (lowering position) based on a cutting operation signal. By holding the roll paper 101 between the paper discharge roller 7 and the spur 7a before the cutting operation, the roll paper 101 can be prevented from being lifted at the time of cutting, and the roll paper 101 can be cut accurately. Since the cutting device 8 is disposed between the paper discharge roller 7 and the paper discharge port, the cut roll paper 101 is discharged to the paper discharge tray 9 by its own weight. The upper surface of the fixed blade 31 disposed on the lower side of the recording medium is positioned lower than the sheet passing surface of the platen 6, and the upper surface (mounting surface) of the paper discharge tray 9 is positioned lower than the upper surface of the fixed blade 31. Therefore, in these, the roll paper 101 is arranged gradually lower in the transport direction.

  Next, with reference to FIG. 2, a series of operations until the cut sheet is fed to the recording apparatus and the recorded cut sheet is discharged to the discharge tray 9 will be described. The paper feed cassette 10 is for loading and storing cut sheets 102 and is detachable from the apparatus main body. The cut sheets 102 stored in the sheet feed cassette 10 are separated one by one by a roller pair including a cut sheet feed roller 11 and a separation roller 12 and conveyed to the intermediate sheet feed roller 13. The intermediate sheet feeding roller 13 is composed of a pair of rollers as conveying means, and conveys the cut sheet 102 to the conveying roller 3.

  When an image is recorded on the cut sheet 102, it is confirmed whether or not the cutting device 8 is in the retracted position retracted upward from the conveyance path. It is moved so as not to interfere with the discharge of the cut sheet 102. The cut sheet 102 is guided to the intermediate sheet feed roller 13 one by one by the cut sheet feed roller 11 and the separation roller 12, and further guided to the transport roller 3 by the intermediate sheet feed roller 13. Then, for the cut sheet 102 conveyed to the image forming unit by the conveyance roller 3, as in the case of the roll sheet 101, image formation for one line by the recording head 70 and sheet feeding at a predetermined pitch are alternately repeated. Record an image on the entire page. The cut sheet 102 is nipped by the nip between the paper discharge roller 7 and the spur 7 a before passing through the conveyance roller 3, and is conveyed toward the outside of the apparatus main body by the paper discharge roller 7 driven in synchronization with the conveyance roller 3. The cut sheet 102 for which image recording has been completed is directly conveyed to the sheet discharge port 71 by the sheet discharge roller 7 and the spur 7 a and is discharged to the sheet discharge tray 9. In the recording apparatus 1 capable of switching the recording medium between the roll paper 101 and the cut paper 102, as described above, the cutting device 8 is disposed between the paper discharge roller 7 and the paper discharge port 71, and the cutting device 8 is connected. By switching between the cutting position on the conveyance path and the upper retracted position, the discharge performance of the recording medium is improved.

  FIG. 3 is a perspective view of the cutting device 8. FIG. 4 is a plan view showing the positional relationship between the rotary blade and the fixed blade of the cutting device 8. FIG. 5 is a plan view illustrating the displacement of the cutting device when the recording medium is cut in a state where the cutting device is not fixed. Next, the cutting device 8 will be described with reference to FIGS. 3, 4 and 5. The cutting device 8 includes a rotary blade unit 20 and a fixed blade unit 30. The rotary blade unit 20 includes a rotary blade 21 and a rotary blade holder 22. The fixed blade unit 30 includes a fixed blade 31, a guide rail 32, a slider 33, a pulley 34, a belt 35, and the like. The rotary blade unit 20 is fixed to a slider 33 that is movable along the guide rail 32 by being connected to a belt 35 stretched between pulleys 34 at both ends. It is connected.

  The fixed blade 31 fixed to the upper surface of the guide rail 32 has a linear shape, and is disposed in a direction (usually a direction orthogonal) intersecting the conveyance direction of the recording medium (continuous paper) 101. The rotary blade 21 held by the rotary blade holder 22 is arranged on the downstream side of the fixed blade 31 in the transport direction, and is held so as to be rotatably contacted with the blade edge 31a of the fixed blade 31 from the downstream side of the transport at a predetermined angle α. Has been. The guide rail 32 is configured to guide the rotary blade unit 20 in the direction of arrow B intersecting the recording medium conveyance direction, and the upper surface thereof is a flat portion parallel to the sheet passing surface of the recording medium. A linear fixed blade 31 is fixed to the upper surface of the flat portion by a fixing means such as double-sided tape or spot welding. A blade edge 31a is provided at the edge of the fixed blade 31 on the downstream side of conveyance in the direction B of the arrow B intersecting (orthogonal) with the conveyance direction of the recording medium. The slider 33 is movable along the guide surface inside the guide rail 32, and the rotary blade unit 20 is held by the slider 33. The slider 33 is connected to a belt 35 that is stretched between pulleys 34 disposed at both ends, and therefore, the belt 35 is driven by a motor (not shown) to move the rotary blade unit 20. The rotary blade 21 can be moved in a direction (arrow B direction) intersecting the transport direction while rotating while being brought into contact with the blade edge 31a of the fixed blade 31.

  Here, the rotary blade 21 and the fixed blade 31 are arranged so as to cut the continuous paper (roll paper) 101 in cooperation with each other, and the cut line of the roll paper 101 substantially matches the cutting edge 31a of the linear fixed blade. To do. When cutting the roll paper 101 while moving the rotary blade 21 in the cutting direction (the right direction of the arrow B in FIG. 4), the rotary blade 21 is inclined at an angle α, so the upstream side of the roll paper 101 is conveyed. Try to bite in. For this reason, the rotary blade 21 cuts the roll paper 101 while applying a pulling force to the roll paper 101 from the conveyance upstream side to the downstream side. Therefore, as the rotary blade 21 moves in the cutting direction (the right direction of the arrow B in FIG. 4), the rotary blade 21 generates a force that exerts a force (biasing force) in a direction toward the upstream side of the roll paper 101. Will receive. Thereby, the cutting device 8 receives a force (biasing force) in a direction in which its posture is rotationally displaced in the direction indicated by the arrow F in FIG.

  Since the cutting device 8 is biased in the direction of arrow F in this way, as shown in FIG. 5, the cutting device 8 that was in the position indicated by the solid line 8a before the start of cutting is indicated by the dotted line 8b when cutting the roll paper 101. As shown, it is displaced to the upstream side of conveyance. That is, the cutting device 8 in the middle of cutting moves to a position urged to the upstream side of the conveyance by the dimension x as indicated by a dotted line 8b. Therefore, the cut line 101a of the roll paper 101 is bent (or inclined) toward the upstream side of the conveyance by the dimension x in the vicinity of the edge on the cutting start side, as shown in the drawing. Note that the dimension x, which is the displacement amount of the cutting device 8, is determined depending on the thickness and rigidity of the roll paper 101, and is larger as the roll paper 101 is thicker and has higher rigidity.

  FIG. 6 is a longitudinal sectional view showing a state in which the cutting device 8 is in the retracted position moved upward from the conveyance path. FIG. 7 is a longitudinal sectional view showing a state in which the cutting device 8 is at a cutting position along the conveyance path. The recording apparatus 1 is provided with elevating means 40 for moving the cutting device 8 between a cutting position where the continuous paper (roll paper) 101 can be cut and a retracted position where the continuous paper (roll paper) 101 is retracted upward. The elevating means 40 has an elevating drive member 41 and an elevating rail 42. Next, the raising / lowering movement of the cutting device 8 by the raising / lowering means 40 is demonstrated.

  The lifting / lowering means 40 driven by a drive source such as a motor (not shown) is provided with a lifting / lowering driving member 41 arranged on the upstream side of the cutting device 8. The cutting device 8 is provided with elevating pins 43 that protrude to the upstream side of conveyance. The raising / lowering pin 43 is being fixed to the fixed blade unit 30 of the cutting device 8, and comprises the raising / lowering input part for receiving the raising / lowering force of an raising / lowering means. The lifting drive member 41 constitutes a lifting drive unit for transmitting a driving force from a driving source such as a motor to the cutting device 8 as a lifting force. With this configuration, the cutting device 8 is driven up and down in the directions of arrows C and D by the lifting means 40 via the lifting pins 43. The elevating rail 42 is arranged on the upstream side of the cutting device 8, and constitutes a position restricting member for guiding the elevating movement of the cutting device 8 and limiting the displacement to the upstream side of the conveying. The elevating rail 42 is arranged to guide the cutting device 8 so as to be movable up and down between a cutting position and a retracted position via an elevating guide 44 provided in the fixed blade unit 30 of the cutting device 8. . Below the cutting device 8, a support portion 45 is provided for supporting the weight of the cutting device when the cutting device 8 is at the cutting position shown in FIG. This support part 45 is arranged on the downstream side of the transport from the center of gravity G of the cutting device 8, and is composed of a lifting rail 42 on the upstream side of the transport of the cutting device 8 that has moved down to the cutting position while being inclined toward the downstream side of the transport. It is for urging (turning) toward the position regulating member.

  When an image is recorded on the cut sheet 102, as shown in FIG. 6, the cutting device 8 is located at a retreat position where it is retracted upward from the conveyance path so as not to disturb the discharge of the cut sheet 102. When recording an image on the roll paper 101, if the cutting device 8 is in the retracted position of FIG. 6, the cutting device 8 is moved in the direction of arrow C by the lifting means 40, and along the conveyance path as shown in FIG. Lower to the cut position. At that time, in order to reduce the sliding load and move the cutting device 8 up and down smoothly, a slight backlash (between the lifting means 40 (the lifting rail 42) and the cutting device 8 (the lifting guide 44) is provided. Clearance is required. When there is no backlash, the sliding load increases remarkably, and there is a possibility that the sliding becomes impossible or the sliding becomes unstable. On the other hand, when such a play is provided, when the cutting device 8 is disposed at the retreat position above the conveyance path, the cutting device 8 uses the upper surface P1 of the lifting guide 44 as a rotation fulcrum and the upper portion is conveyed downstream. It will be tilted to the side. That is, the cutting device 8 is supported so as to be rotatable around a fulcrum extending in a direction intersecting with the conveying direction formed by the upper surface P <b> 1 of the lifting guide 44. Then, when the cutting device 8 is lifted and lowered by the lifting and lowering means 40, the cutting device 8 is lifted and lowered in a tilted posture (a posture in which it is rotationally displaced) in which the lower side surface is in contact with the position regulating member 42.

  Therefore, when the cutting device 8 that has been in the retracted position is lowered to the vicinity of the cutting position, the bottom surface of the cutting device 8 comes into contact with the support portion 45 in a state in which the cutting device 8 is inclined to the downstream side of conveyance. Then, the cutting device 8 uses the upper surface P1 of the elevating guide 44 that forms a rotation fulcrum extending in the direction intersecting the conveyance direction as a rotation fulcrum (rotation center) at a portion P2 on the conveyance downstream side of the gravity center G of the bottom surface. The support reaction force from the support part 45 is received. When the bottom surface P <b> 2 of the cutting device 8 is supported by the support portion 45 in this way, the rotation fulcrum governing the posture of the cutting device 8 is contacted with the support portion 45 from the upper surface P <b> 1 of the lifting guide 44. To change. In this state, when the cutting device 8 is further lowered by the lifting and lowering means 40, the support portion 45 is positioned on the downstream side of conveyance with respect to the center of gravity G of the cutting device 8. For this reason, the cutting device 8 supported by the support part 45 rotates in the direction in which the upper part of the cutting device 8 moves to the upstream side of conveyance with the bottom surface P2 as a rotation fulcrum. The rotation fulcrum P2 on the bottom surface forms a rotation fulcrum extending in a direction intersecting the transport direction. As a result, the entire cutting device 8 rotates to the transport upstream side with the bottom surface P2 as a rotation fulcrum. In the cutting position, the upper surface (upper side surface) P3 of the cutting device 8 is in contact with and pressed against the position regulating member (elevating rail) 42. Thereby, the cutting device 8 is held in an appropriate posture in a state where the play is pressed at the cutting position.

  When the cutting device 8 is moved upward in the direction of the arrow D from the cutting position (FIG. 7) to the upper retracted position (FIG. 6), the reverse action of the downward movement described above can be given. it can. That is, with the upward movement, the cutting device 8 uses the bottom surface P2 extending in the direction intersecting the transport direction as a rotation fulcrum, and the upper surface P3 of the cutting device 8 forming the fulcrum extending in the direction intersecting the transport direction is While being separated, the upper part is inclined (rotated) in the direction of moving to the downstream side of conveyance. When the upper surface P1 of the lifting guide 44 is pressed against the lifting rail 42, the cutting device 8 reaches the retracted position shown in FIG.

  In the recording apparatus described above, the cutting device 8 that cuts the continuous paper by moving the rotary blade along the fixed blade, and the cutting device 8 retracts upward from the cutting position (FIG. 7) where the continuous paper 101 can be cut. Elevating means 40 for moving between the retracted position (FIG. 6). The cutting device 8 includes a linear fixed blade 31 arranged in a direction intersecting the conveyance direction of the continuous paper 101, and a rotary blade that abuts the fixed blade 31 so as to be rotatable at a predetermined angle α from the conveyance downstream side. 21. Therefore, when the cutting device 8 is moved to the cutting position by the lifting means 40, the upper portion of the cutting device 8 is on the upstream side of the conveyance centering on the upper surface P1 of the lifting guide 44 that forms a fulcrum extending in the direction intersecting the conveyance direction. Rotate in the direction to move to. Thereby, it is comprised so that the cutting device 8 may be contact | abutted to the position control member 42 of the conveyance upstream. According to such a configuration, it is possible to reduce the load when the cutting device 8 for cutting the continuous paper 101 is moved up and down, and to make the cut line when cutting the continuous paper straight, thereby making the continuous paper easy. It can be cut accurately.

  That is, according to the embodiment described above, when the cutting device 8 is moved up and down between the cutting position and the retracted position retracted upward from the conveyance path, the cutting device 8 slides on the lifting means 40. A slight backlash (clearance, clearance) will be provided. Therefore, the sliding load during the up-and-down movement is reduced, and the cutting device 8 can be moved up and down smoothly. Further, when the cutting device 8 is moved down to the cutting position, when the cutting device 8 is lowered to the cutting position, in order to rotate the cutting device 8 to the upstream side of the conveyance, a support disposed on the downstream side of the conveyance from the center of gravity G of the cutting device 8 It is in contact with the portion 45. Therefore, by pressing the cutting device 8 against the (up-and-down rail) 42 as the position regulating member on the upstream side of the conveyance, the backlash of the cutting device 8 can be suppressed, and the cut line of the continuous paper 101 can be made straight. It becomes possible to cut the continuous paper 101 easily and accurately.

[Second Embodiment]
FIG. 8 is a longitudinal sectional view showing a state in which the cutting apparatus according to the second embodiment is in a position retracted upward from the conveyance path. FIG. 9 is a longitudinal sectional view showing a state in which the cutting device of FIG. 8 is in a cutting position along the conveyance path. 8 and 9, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The recording apparatus 1 is provided with elevating means 50 for moving the cutting device 8 between a cutting position where the continuous paper (roll paper) 101 can be cut and a retracted position where the continuous paper (roll paper) 101 is retracted upward. The elevating means 50 has an elevating drive member 51 and an elevating rail 42. The lifting drive member 51 constitutes an output member for transmitting the lifting force of the lifting means 50 to the cutting device 8. The elevating rail 42 is a member that guides the lifting and lowering movement of the cutting device 8 and restricts the displacement to the upstream side of the conveyance, and constitutes a position restricting member for restricting the position and orientation of the cutting device 8 together with the guide member. .

  The lifting / lowering means 50 driven by a driving source such as a motor (not shown) is provided with a lifting / lowering driving member 51 arranged on the upstream side of the cutting device 8. The cutting device 8 is provided with elevating pins 43 that protrude to the upstream side of conveyance. The raising / lowering pin 43 is being fixed to the fixed blade unit 30 of the cutting device 8, and comprises the raising / lowering input part for receiving the raising / lowering force of an raising / lowering means. The elevating drive member 51 constitutes an elevating drive unit for transmitting a driving force from a driving source such as a motor to the cutting device 8 as the elevating force. With this configuration, the cutting device 8 is driven up and down in the directions of arrows C and D by the lifting means 50 via the lifting pins 43. The elevating rail 42 is arranged on the upstream side of the cutting device 8, and constitutes a position restricting member for guiding the elevating movement of the cutting device 8 and limiting the displacement to the upstream side of the conveying. The elevating rail 42 is arranged to guide the cutting device 8 so as to be movable up and down between a cutting position and a retracted position via an elevating guide 44 provided in the fixed blade unit 30 of the cutting device 8. . Below the cutting device 8, a support portion 55 for supporting the weight of the cutting device when the cutting device 8 is at the cutting position shown in FIG. The support portion 55 is disposed on the transport downstream side of the lift pins 43 that constitute the lift input portion of the cutting device 8. The support portion 55 is disposed so as to support the bottom surface of the cutting device 8 on the downstream side of the conveyance with respect to the center of gravity G of the cutting device 8, and has been moved downward to the cutting position while being inclined toward the downstream side of the conveyance. This is for urging (turning) 8 toward a position restricting member composed of a lifting rail 42 on the upstream side of conveyance.

  Other configurations of the recording apparatus according to the present embodiment are the same as those of the first embodiment. Next, an operation when the cutting device 8 is moved up and down in the directions of arrows C and D by the lifting means 50 will be described. The support portion 55 is disposed on the downstream side of the lifting / lowering drive member 51 serving as the lifting / lowering drive portion and on the bottom surface side of the cutting device 8 and supports the weight of the cutting device 8 at the cutting position. Between the cutting device 8 (its elevation guide 44) and the elevation means 50 (its position regulating member 42), a play (gap, play) is provided to ensure smooth elevation movement. Therefore, the load at the time of raising / lowering the cutting device 8 can be reduced and moved smoothly. On the other hand, as shown in FIG. 8, when the cutting device 8 is located at the retracted position above the conveyance path, the upper portion of the upper and lower guides 44 as the rotation fulcrum extending in the direction intersecting the conveyance direction is conveyed downstream. It is tilted to the side.

  When the cutting device 8 is lowered in the direction of the arrow C from the retracted position in FIG. 8 to the cutting position in FIG. 9, the cutting device 8 uses the upper surface P1 of the lifting guide 44 as a rotation fulcrum extending in the direction intersecting the conveying direction. Therefore, the lower portion of the side surface of the cutting device 8 comes into contact with the position regulating member 42 and slides. When the cutting device 8 is lowered to the vicinity of the cutting position, the bottom surface of the cutting device 8 comes into contact with the support portion 55 in a state where the cutting device 8 is inclined toward the conveyance downstream side, and the weight of the cutting device 8 is supported from the support portion 55. It becomes a state supported by force. When the lowering drive by the lifting / lowering means 50 is continued in a state where the bottom surface of the cutting device 8 is supported by the support portion 55, the upper surface P4 of the lifting / lowering pin (lifting / lowering input portion) 43 becomes the lifting / lowering driving member disposed on the upstream side of conveyance. 51 (the raising / lowering drive part which consists of the press surface) is pushed down by the arrow C direction. At that time, the cutting device 8 rotates around a bottom surface P2 (a contact portion with the support portion 55) serving as a rotation fulcrum extending in a direction intersecting the conveyance direction. Therefore, in the cutting device 8, the entire cutting device 8 rotates about the bottom surface P <b> 2 supported by the support portion 55 until the upper surface 43 of the elevating pin 43 comes into contact with the position restricting member 42.

  As a result, the cutting device 8 is supported by the bottom surface P <b> 2 that forms a rotation fulcrum at the cutting position (FIG. 9), and the upper surface P <b> 3 of the cutting device 8 is pressed against the position regulating member 42. Therefore, the cutting device 8 is held in the correct cutting posture with the backlash held at the cutting position. That is, in the present embodiment, when the cutting device 8 is in the cutting position, the lifting drive member 51 that is the lifting drive unit causes the pressing force of the lifting means 50 to act on the upper surface P4 of the lifting pin 43 that is the lifting input unit. It is configured. In this embodiment, when the cutting device 8 is moved to the cutting position by the elevating means 50, the cutting device 8 rotates around the fulcrum extending in the direction intersecting the conveying direction at the cutting position, and the conveying upstream. It is biased toward the position regulating member 42 located on the side. Therefore, the cutting device 8 is rotated with the bottom surface P2 as a fulcrum, and the upper surface P3 of the cutting device 8 is held in the correct cutting posture by abutting against the position regulating member 42.

  Thus, also in this embodiment, when the cutting device is moved up and down, the necessary play is secured, and at the cutting position, the cutting device 8 is biased toward the position regulating member 42 on the upstream side of the conveyance to reduce or reduce the play. It can be held in a proper posture in the state of being lost. Therefore, according to the present embodiment as well, it is possible to reduce the load when moving up and down the cutting device 8 for cutting the continuous paper 101, and also to make the cut line straight when cutting the continuous paper. It becomes possible to cut easily and accurately. Also in this embodiment, when the cutting device 8 is moved upward in the direction of the arrow D from the cutting position in FIG. 9 to the retracted position in FIG. 8, as in the first embodiment, Can be moved smoothly with reduced load by the reverse operation and action. In addition, the recording apparatus according to the present invention can be implemented in various modes without being limited to the above-described embodiment as long as the entire cutting apparatus moves, and the present invention covers these in the technical scope. Is included.

  In the above embodiment, the ink jet recording apparatus has been described as an example. However, the present invention is applied to an image forming apparatus that forms an image by other methods such as a thermal transfer type, a laser beam type, a heating type, and a wire dot type. Is equally applicable. Further, the present invention provides a recording operation method such as a serial method in which recording is performed by alternately repeating main scanning by a recording head and sub-scanning by a conveying operation, and a line method in which recording is performed continuously only by sub-scanning by a conveying operation. Regardless, it is equally applicable. The present invention can be similarly applied regardless of the number of recording heads, the type of ink used, the number of properties, and the like. The present invention is also applicable to the case where various different materials such as paper, plastic film, photographic paper, and non-woven fabric are used as the recording medium.
