Description

  The present invention relates to a printer apparatus that pulls out a paper from a paper roll having a long paper wound around a core and performs a printing process on the paper.

  2. Description of the Related Art Conventionally, there has been provided a printer device that forms an image by performing printing processing such as printing, exposure / development processing, etc. on paper as a recording medium.

  Such a printer apparatus includes a paper supply unit that accommodates a paper roll (hereinafter referred to as a roll) so that paper to be printed can be pulled out. The roll is obtained by winding a long paper around a core, and is accommodated in a paper supply unit while being held by a paper roll reel (hereinafter referred to as a reel). The reel is attached to the shaft body so as to sandwich the shaft body inserted through the core body of the roll and the roll through which the shaft body is inserted from the axial direction, and regulates movement of the roll in the axial direction. And a support shaft that is pivotally supported in the paper supply unit is provided at both ends of the shaft body.

  The paper supply unit includes a pair of bearing bodies arranged at intervals that can interpose a reel, and each bearing body can be fitted / detached with a support shaft in a direction orthogonal to the axis and can support the support shaft. A configured bearing recess is formed. Thus, by forming the bearing recesses in the pair of bearing bodies, the paper can be pulled out from the roll that is supported by the reel by supporting the support shaft of the reel, and the reel is removed from the paper supply section. Can be exchanged.

  By the way, the paper supply unit pulls out the paper in the direction in which the support shaft of the reel escapes (extracts) from the bearing recess due to the arrangement of the printing unit that performs the printing process on the paper and the configuration of the conveyance path for conveying the paper. May be configured as follows. That is, the paper supply unit may be configured such that the direction in which the bearing recess of the bearing body is dug and the direction in which the paper is drawn out are substantially the same.

  When the paper supply unit is configured in this way, the reel is not fixed at a predetermined position (the support shaft is in the bearing recess) due to the action of the pulling force by pulling out the paper, and there is a problem that the conveyance stability of the paper is impaired. is there. In particular, when paper is consumed after printing is performed, the weight of the roll is reduced, and the weight of the roll does not fully resist the pulling force, and the support shaft can easily move within the bearing recess or escape from the bearing recess. It becomes remarkable that the conveyance stability of the paper is impaired.

  Therefore, in view of such circumstances, the present invention provides a printer device that can improve the mounting and fixing properties of a paper roll reel that holds a paper roll and can stably supply paper from the paper roll. Let it be an issue.

A printer apparatus according to the present invention includes a paper supply unit configured to be able to pivotally support a paper roll reel holding a paper roll and to be able to pull out a paper to be printed from the paper roll. The portion includes a pair of bearing bodies in which bearing recesses are formed so that the support shafts protruding from both ends of the paper roll reel can be fitted and removed in a direction orthogonal to the shaft center, and the support shafts escape from the bearing recesses. The paper supply unit includes a shaft regulating body that regulates movement of the support shaft in the bearing recess in the withdrawal direction at least in a state where the paper is pulled out. wherein the shaft regulating body, together are slidable in a direction intersecting the depth direction of the bearing recess, the shaft to the tip of the sliding direction A restricting portion for restricting the movement of the support shaft in the recess is protruded, and the restricting portion restricts the movement of the support shaft by sliding the shaft restricting body, and the restriction on the support shaft by the restricting portion. It is configured to be switchable to a release position for releasing .

  According to such a printer apparatus, the paper supply unit includes the shaft restricting body that restricts the support shaft in the bearing recess from moving in the escape direction at least in a state where the paper is pulled out. Even when a force that causes the support shaft of the paper roll reel to escape from the bearing recess acts, the movement of the support shaft is restricted by the shaft restricting body. Thereby, the mounting stability of the paper roll reel in the paper supply unit can be improved, and as a result, the paper supply stability can be improved.

Further, according to the printer device having the above-described configuration, the shaft restricting body is provided to be slidable in a direction intersecting the digging direction of the bearing concave portion, and restricts the movement of the support shaft in the bearing concave portion at the tip in the sliding direction. A restriction part for projecting is provided, and by sliding the shaft restriction body, the restriction part can be switched between a restriction position for restricting the movement of the support shaft and a release position for releasing the restriction on the support shaft by the restriction part. Because it is configured, switching between the state where the movement of the support shaft is restricted and the state where the support shaft can be removed from the bearing recess (the state where the paper roll reel is removed) is possible simply by sliding the shaft restricting body. Can do.

Furthermore, as one aspect of the present invention, the bearing body and the shaft restricting body are formed to extend in a substantially horizontal direction, and the bearing body is formed by digging a bearing concave portion from a predetermined position on the upper surface. The body is preferably attached to the bearing body so as to be slidable in the extending direction, and the upper surfaces of the bearing body and the shaft restricting body are preferably configured as guide surfaces for guiding the support shaft to the bearing recess. In this case, when the paper roll is heavy, it is not necessary to directly arrange the support shaft of the paper roll reel that holds the heavy paper roll in the bearing recess, and the paper roll on the guide surface. The support shaft can be guided to the bearing recess only by rolling the roll reel. In particular, since the shaft restricting body is provided so as to be slidable in the extending direction, when the restricting portion of the shaft restricting body is slid in a direction away from the bearing recess, the guide surface extends in the sliding direction. It is effective when the area where the paper roll reel is accommodated is deep. That is, when the shaft restricting body is slid, the guide surface of the bearing body is extended in the sliding direction by the guide surface of the shaft restricting body, and the shaft support position of the paper roll reel is recessed in the paper supply unit. Even in such a position, the operator can attach a heavy paper roll (paper roll reel) with an easy posture.

  The shaft restricting body is formed with a shaft fitting recess that is dug from the front end toward the rear end, and one of the pair of projecting pieces formed between the shaft fitting recesses. The restricting portion may be configured by a shape portion. In this way, in a state where the restricting portion restricts the support shaft, the support shaft is positioned in an opening defined by overlapping the bearing recessed portion and the shaft fitting recessed portion, and the support shaft is reliably restrained. And the paper roll reel can be reliably fixed at a predetermined position.

  Further, the paper supply unit is provided in a housing having an openable / closable door, and the shaft restricting body is configured to slide in conjunction with opening / closing of the door, and is in a restricted position in a state of being closed with the door. On the other hand, it is preferable to be configured to be positioned at the release position with the door open. In this way, the support shaft can be restricted and released simply by opening and closing the door.

  As described above, the printer device according to the present invention improves the mounting stability of the paper roll reel that holds the paper roll, and has an excellent effect that the paper can be stably supplied from the paper roll. obtain.

  The pair of support portions 40 and 41 are provided so as to constitute a part of the transport path in the vicinity of the discharge port 44. More specifically, the one support portion 40 provided on the upstream side is a guide body 40 (specifically, a corner described later) arranged side by side on the upstream-side conveyance roller pairs 400. Part 40c). The guide body 40 is formed by bending a plate into an L shape so as to round the bent portion, and the upstream side conveyance is performed so that one piece 40a is along the upstream conveyance path. Adjacent to the roller pair 400 on the downstream side, the other piece 40b is disposed to extend downward in the orthogonal direction with respect to the transport path. Thus, the guide body 40 can support the paper P being conveyed by the corner portion 40c. The guide body 40 has an opening at a bent portion (corner portion 40c), and detects the presence or absence of the paper P on the decurling portion 4 (guide body 40) through the opening inside the corner portion 40c. A sensor 48 is provided.

  The other support portion 41 is composed of a roller (hereinafter referred to as a support roller), is spaced from the corner portion 40c of the guide body 40, and is positioned below the upstream conveyance path. It is provided at the displaced position. In the present embodiment, a pressure roller 45 that is pressed against the support roller 41 is provided so that the paper P supported by the support roller 41 can be conveyed by pressure. The pressure tangent line between the support roller 41 and the pressure roller 45 is provided so that it is substantially parallel to the slit-shaped discharge port 44 and the pressure-contacted paper P is guided to the discharge port 44 without changing its posture. ing.

  The pressing roller 43 is provided so as to be able to press the paper P between the pair of support portions 40 and 41 (the corner portion 40c of the guide body 40 and the support roller 41) so as to bend the paper P to the side opposite to the curl. Yes. Specifically, the pressing roller 43 is an extension of a virtual line (not shown) that connects the pressure contact line between the support roller 41 and the pressure roller 45 and the discharge port 44 at the downstream portion of the paper P that is bent by pressing. The paper P is pressed so as to be positioned at the position. That is, the rollers 41, 43, 45, and 46 are arranged so that the pressure contact line of the pressure roller 43 and the pressure receiving roller 46, the pressure contact line of the support roller 41 and the pressure roller 45, and the virtual line connecting the discharge port 44 are substantially straight. By being arranged, a straight conveyance path connected to the discharge port 44 is formed on the extended line of the posture of the paper P straddling the pressing roller 43 and the supporting roller 41 at the pressing position PP.

  In the present embodiment, a pressure receiving roller 46 capable of being pressed against the pressing roller 43 located at the pressing position PP is provided so that the paper P being pressed (decaled) can also be conveyed by the pressing roller 43. In the present embodiment, the pressure receiving roller 46 is provided so as to be positioned directly below the pressing roller 43 positioned at the pressing position PP. Each of the pressing roller 43 and the pressure receiving roller 46 according to the present embodiment has an outer periphery made of a soft material. A guide plate 47 is provided between the support roller 41 and the pressure roller 45 so that the paper P being decurled can be reliably guided onto the support roller 41.

  The roller position switching means 50 operates based on the detection result of the sensor 48 that detects the presence or absence of the paper P through the opening of the guide body 40, and the sensor 48 does not detect the paper P. Thus, the pressing position 43 where the pressing roller 43 presses the paper P in the state where the pressing roller 43 is positioned at the pressing release position PR (see FIG. 9) that does not press the paper P and the sensor 48 detects the paper P (FIG. 10). Reference) is configured.

  The roller position switching means 50 according to the present embodiment includes a pair of arms 500 and 500 that support both ends of the pressing roller 43, a drive motor 510, a first arm 520 attached to the output shaft 511 of the drive motor 510, A pair of second arms 530 and 530 are configured to rotate following the rotation of the first arm 520 and rotate the arms 500 and 500.

  Each of the pair of arms 500 and 500 has an arm main body 501 whose one end is pivotally attached to a frame 533 in the housing E, and the other end of the arm main body 501 is orthogonal to the extending direction of the arm main body 501. The shaft support portion 502 projects in the direction and supports the end portion of the pressing roller 43.

  One end of the arm body 501 is pivoted on the upstream side of the one piece 40a of the guide body 40 and on the upstream side of the corner portion 40c of the guide body 40. In this embodiment, the guide body 40 In contrast, it is pivotally mounted so as to be concentric with one of the rollers 400a located on the upper side of the conveying path of the conveying roller pair 400 adjacent on the upstream side. On the other end side of the arm main body 501, a guide hole 503 into which a cam follower 531 described later of the second arm 530 is fitted is formed in a long hole shape extending in the longitudinal direction.

  The drive motor 510 is a pulse motor, and is controlled so as to rotate the output shaft 511 at a predetermined rotation angle. The first arm 520 is fixed to the output shaft 511 in a non-rotatable manner, and a cam follower 521 is attached to the tip of the first arm 520 so that the rotation axis is parallel to the axis of the output shaft 511.

  The pair of second arms 530 and 530 are provided so as to sandwich the pair of arms 500 and 500. One end of the pair of second arms 530 and 530 is connected via a connecting shaft 532 substantially parallel to the output shaft 511 of the drive motor 510, and is pivotally attached to the frame 533 so as to be rotatable around the connecting shaft 532. ing. In each of the pair of second arms 530, a cam follower 531 is pivotally attached to the front end portions of the opposing surfaces, and the cam follower 531 is interposed in the guide hole 503 of the arm body 501. One of the second arms 530 located on the drive motor 510 side includes a pair of rail pieces 534 and 534 that are folded back on the frame 533 (drive motor 510) side at both ends in the direction orthogonal to the extension direction. A cam follower 521 pivotally attached to the first arm 520 is interposed between the pieces 534 and 534. Accordingly, the pair of second arms 530 follow the rotation of the cam follower 521 accompanying the rotation of the output shaft 511 of the drive motor 510 (rotation of the first arm 520) so as to rotate around the axis of the connecting shaft 532. It is configured.

  The roller position switching means 50 configured as described above rotates the pair of second arms 530 and 530 around the connecting shaft 532 as described above, and thereby the pair of arms are cam followers 531 pivotally attached to the second arms 530 and 530. 500 and 500 are rotated, and the pressing roller 43 is switched between the pressing position PP and the pressing release position PR. In addition, the roller position switching means 50 rotates the pair of arms 500 and 500 by the cam followers 531 and 531 pivotally attached to the pair of second arms 530 coupled via the coupling shaft 532. When the roller 43 is positioned at the pressing position PP, a load (pressing force) is applied to both ends of the pressing roller 43, and when the pressing roller 43 comes into pressure contact with the pressure receiving roller 46, a uniform pressing force is applied over the entire length. It comes to work.

  The decurling unit 4 configured as described above transports the paper P faster than the transport speed of the paper P in the upstream transport path, and discharges the subsequent paper P from the discharge port 44 with a close interval with the preceding paper P. I am doing so. That is, in the decurling unit 4, the set rotational speeds of the pressure roller 43, the pressure receiving roller 46, the support roller 41, and the pressure roller 45 are set to be higher than the set rotational speeds of the upstream conveying roller pairs 400. In the section 4, while decurling the paper P, the preceding paper P is chased to a predetermined interval, and each processing can be performed by reducing the interval of each paper P (increasing processing efficiency). However, when the paper P is long and straddles the printing unit 2 and the decurling unit 4, the decurling is performed so that the pressure-conveying (pulling) in the decurling unit 4 does not adversely affect the printing in the printing unit 2. The conveyance speed in the unit 4 is the same as the conveyance speed in the printing unit 2, and the conveyance speed is switched to high speed after the paper P is cut by the cutting unit 3. In order to make the conveyance speed in the decurling unit 4 the same as the conveyance speed in the printing unit 2, the pressure roller 43 and the pressure receiving roller 46 are rotated at the same speed as the upstream conveyance roller pair 400, The roller 46 may be rotated at a higher speed than the upstream conveying roller pair 400 so that the pressure on the paper P is weakened and slipped.

  Returning to FIG. 1, the laminating apparatus E <b> 2 conveys the paper P discharged from the discharge port 44 as it is, and laminates the paper P discharged from the discharge port 44 and the first path A for discharging the paper P to the outside. And a distribution unit 7 that switches the transport direction of the paper P to the second path B in the middle of the first path A.

  The first path A is composed of a plurality of conveyance roller pairs (not numbered), and is formed so as to extend straightly the conveyance path from the decurling unit 4 to the discharge port 44 of the printer E1, It is configured so that the processed paper P can be discharged onto a tray 8a provided outside. On the second path B, a laminating section 9 is formed for laminating the printed paper P. The laminate unit 9 is configured to convey a laminate material X in which a laminate layer is laminated on a sheet-like base material and an under film Y that transfers the laminate layer of the laminate material X so as to face each other, Paper P is supplied between the laminate material X and the under film Y, and these three members are pressure-bonded and conveyed by a pair of heating rollers 90 having a heater at the axial center, thereby recording the recording surface of the paper (print) P. The laminate layer is heated and pressure-bonded, and the laminate layer protruding from the paper P is transferred to the under film Y.

  Then, by separating the under film Y from the paper P, the protruding laminate layer is separated from the laminate layer on the paper P by the edge action of the end portion of the paper P, and the base material is removed from the laminate layer on the paper P. By peeling, a laminate layer can be formed on the recording surface of the paper P. The laminated paper (print) P is transported on the second path B and discharged to a tray 8b provided outside.

  The printer apparatus E1 according to the present embodiment and the laminating apparatus E2 mounted on the printer apparatus E1 are configured as described above. Next, a method for mounting the roll R and the operation of the printer apparatus E1 will be described.

  First, it mounts | wears with the position corresponding to the size of the roll R holding the regulation bodies 110 and 110 with respect to the axial body 100 of the reel 10 of the said structure. Specifically, one regulating body 110 is mounted at a predetermined position on one end side of the shaft main body 101. At this time, as shown in FIG. 5, the rotating body 120 is rotated so that the longitudinal center line CL2 of the rotating body 120 and the longitudinal center line CL3 of the reel plate 113 are inclined. In this state, the pair of pins 112 and 112 are in a posture along the inner surface of the shaft insertion hole 111a of the reel plate 113 (core fitting portion 115), and the shaft main body 101 can be inserted.

  Then, the shaft body 101 is inserted into the insertion portion 111 so that the first surface 105 of the shaft body 101 faces the inner surface of the opening 111b of the core fitting portion 115 and the pins 112, 112, and the size of the roll R to be held is maintained. The restrictors 110, 110 and the shaft body 101 are relatively moved in the axial direction to the position where the corresponding grooves 104a, 104b, 104c... And the pins 112, 112 are aligned. Then, when the regulating bodies 110, 110 reach an appropriate position, the rotating body 120 is rotated so that the longitudinal center lines CL2, CL3 of the reel plate 113 and the rotating body 120 coincide as shown in FIG. Note that the opening 111 b of the reel plate 113 is formed so that the opposing inner surface corresponds to the interval between the first surfaces 105, 105 of the shaft body 101, so that the reel plate 113 is around the axis of the shaft body 101. Is restricted, and only the rotating body 120 rotates. When the rotating body 120 is rotated, the pins 112 and 112 are pushed outward corresponding to the outer peripheral shape of the shaft main body 101, but the pins 112 and 112 are urged toward the insertion center CL 1 by the coil springs 123 and 123. Therefore, the grooves 104a, 104b, 104c... Sequentially enter the grooves 104a, 104b, 104c... And finally fit into the grooves 104a, 104b, 104c. , 112 and the grooves 104a, 104b, 104c... Are restricted from moving in the direction of the axis CL1.

  Thereafter, the shaft main body 101 is inserted into the core body of the roll R, and the other regulating body 110 is mounted at a predetermined position on the other end side of the shaft main body 101. The mounting of the regulating bodies 110 and 110 is performed in the same manner as the one regulating body 110.

  When the pair of regulating bodies 110, 110 are thus mounted on the shaft body 100, the reel plate 113 extends outside the outer periphery of the roll R as shown in FIG. Therefore, it is possible to prevent the roll R from being damaged even if the reel 10 is placed in a lying state for performing other operations.

  Then, the reel 10 is mounted on the paper supply unit 1. In this case, as shown in FIG. 7 (a), when the door D is opened, the shaft regulating bodies 16 and 16 of the paper supply unit 1 are on the door D side (released). The shafts 102b and 103b of the support shafts 102 and 103 provided at both ends of the reel 10 are placed on the upper surfaces (extension guide surfaces G2) of the shaft restrictors 16 and 16, respectively. Put. When the reel 10 is pushed into the paper supply unit 1 (toward the back), the support shafts 102 and 103 (shaft portions 102b and 103b) are extended guides for the shaft restricting bodies 16 and 16 and the bearing bodies 15 and 15, respectively. It is guided by the surface G2 and the guide surface G and is introduced into the bearing recess 150. That is, since the support shafts 102 and 103 are provided with the flange portions 102c and 103c, the upper ends of the shaft regulating bodies 16 and 16 and the bearing bodies 15 and 15 are used as rails (the movement in the axial direction is within a predetermined range). The shaft portions 102 b and 103 b are guided into the bearing recess 150.

  As shown in FIG. 7B, when the door D is closed, the shaft restricting bodies 16 and 16 slide, and the restricting portion 160 protrudes on the shaft portions 102b and 103b fitted in the bearing recess 150, so that the reel 10 moves. Will be regulated. That is, the shaft restricting bodies 16 and 16 slide along the bearing bodies 15 and 15, the shaft portions 102 b and 103 b supported by the bearing recessed portion 150 are fitted into the shaft fitting recessed portion 161, and the shaft fitting recessed portion 161 is sandwiched therebetween. The pair of projecting piece-like portions thus formed enters between the bearing bodies 15 and 15 and the flange portions 102c and 103c of the support shafts 102 and 103. Then, one protruding piece-like portion functions as the restricting portion 160, restricting the upward movement of the support shafts 102 and 103 (in the direction of escape from the bearing recess 150), and mounting of the roll R (reel 10) is completed. .

  Then, when the paper P is pulled out from the roll R in the paper supply unit 1 toward the upper printing unit 2 and sequentially supplied, the printing unit 2 performs a printing process on the recording surface of the paper P, and the downstream side. It is cut into a predetermined size by the side cutting portion 3. When the output size of the paper P is long, the cutting unit 3 does not operate until the paper P reaches a predetermined length, and the paper P is sequentially conveyed toward the downstream side. When straddling the laminating apparatus E2, a loop is formed in the loop portion 6 (see FIG. 1).

  Then, the paper P that has reached the decurling unit 4 has its curl corrected by being pressed by the pressing roller 43. Specifically, as shown in FIG. 9, the paper P is fed from the upstream side while the pressing roller 43 is waiting at the pressing release position PR. Then, after the sensor 48 detects the presence (presence / absence) of the paper P from the opening 111b of the guide body 40 and a predetermined time elapses (when the leading end of the paper P sufficiently protrudes from the corner portion 40c of the guide body 40), The roller position switching means 50 is operated, and the pressing roller 43 is lowered toward the pressing position PP. Then, as shown in FIG. 10, the front end portion of the paper P protruding forward along one piece portion 40 a of the guide body 40 is pushed by the pressing roller 43, and the paper P is formed at the corner portion 40 c of the guide body 40. In addition to being bent, the pressure roller 43 is bent in the direction opposite to the curl. In this embodiment, the pressure receiving roller 46 is provided, so that the paper P is pressure-bonded to the pressure roller 43 and the pressure receiving roller 46. Will be.

  Then, the paper P is sent to the downstream side by the pressing roller 43 and the pressure receiving roller 46, and is pressure-bonded to the support roller 41 and the pressure roller 45 as a support portion on the downstream side. Note that the rotation of the support roller 41 and the pressure roller 45 is set faster than the rotation of the pressing roller 43 and the pressure receiving roller 46, and the paper P is wound (pulled) around the pressing roller 43. ing. As a result, the paper P passing through the decurling unit 4 (pressing roller 43) is pulled to the downstream side while being bent to the opposite side of the curl, and the curl is forcibly corrected.

  The rollers 41, 43, 45, 46 are arranged so that the pressure contact line of the pressing roller 43 and the pressure receiving roller 46, the pressure line of the support roller 41 and the pressure roller 45, and the imaginary line connecting the discharge port 44 are substantially straight. Therefore, the paper P that has passed through the decurling unit 4 (downstream support roller 41) is conveyed without being bent in the same direction as the curl, and the paper P is discharged in a straight posture. Will be discharged from.

  Returning to FIG. 1, the paper P discharged from the discharge port 44 of the printer apparatus E <b> 1 is sent to the laminating apparatus E <b> 2, and on the extension line of the imaginary line connecting the decurling unit 4 and the discharge port 44 when lamination is not performed. In the straight first path A formed in a straight line, the paper is discharged onto the tray 8a in a straight posture. On the other hand, when laminating the paper P, the paper P sent from the printer device E1 is guided to the second path B by the sorting unit 7, and after being laminated by the laminating unit 9, is discharged onto the tray 8b. Is done.

  As described above, the paper supply unit 1 of the printer apparatus E1 according to this embodiment has the shaft restricting body that restricts the support shafts 102 and 103 in the bearing recess 150 from moving in the escape direction when the paper P is pulled out. 16, even when a force that causes the support shafts 102 and 103 of the reel 10 to escape from the bearing recess 150 is applied when the paper P is pulled out, the shaft restriction body 16 allows the support shafts 102 and 103 to move. Be regulated. As a result, the reel 10 can be fixed at a predetermined position in the paper supply unit 1 to achieve mounting stability, can be fixed at the position, and the paper P can be supplied stably.

  Further, the shaft restricting bodies 16 and 16 are provided so as to be slidable in a direction intersecting the direction in which the bearing recessed portion 150 is dug down, and the support shafts 102 and 103 in the bearing recessed portion 150 are provided at the distal ends of the shaft restricting bodies 16 and 16 in the sliding direction. Since the restricting portion 160 that restricts the movement of the bearing concave portion 105 toward the opening side (the escape direction) protrudes, the restricting portion 160 can be attached to the support shaft 102, simply by sliding the shaft restricting bodies 16, 16. It is possible to switch between a restriction position for restricting the movement of 103 and a release position for releasing the restriction of the support shafts 102 and 103 by the restriction portion 160.

For example, a positioning function is added to the connecting portion 102a and the flange portion 102c in addition to the function of restricting movement in the axial direction. May be. That is, the taper which tapered the mutually opposing surface of the connection part 102a and the collar part 102c of either one of a pair of support shafts 102 and 103 (preferably the support shaft 102 provided with the gear 102d) toward the other party. A groove having a substantially inverted trapezoidal shape or a substantially inverted V-shaped cross section may be formed by the connection portion 102a, the shaft portion 102b, and the flange portion 102c. In this way, when the reel 10 (support shafts 102 and 103) rolls on the bearing body 15 (guide surface G), the taper surface of the one support shaft 102 (the taper surfaces of the connection portion 102a and the flange portion 102c). ), The shaft portion 102b between the connecting portion 102a and the flange portion 102c is guided onto the guide surface G, and the reel 10 can be reliably aligned with the bearing body 15. In this case, since the reel 10 moves in the axial direction when the shaft portion 102b is guided on the guide surface G (extended guide surface G2) by the tapered surface, the shaft of the other support portion 103 is allowed to allow the movement. Of course, the portion 103b (the interval between the connecting portion 103a and the flange portion 103c) is set to a length that can move in the axial direction on the guide surface G of the bearing body 15. Further, when the shaft restricting body 16 is configured in the same manner as in the above embodiment, in addition to considering the allowance of movement in the axial direction, the flange portion 103c of the support shaft 103 located in the bearing recess 150 and the bearing body 15 Needless to say, the length is set so that the shaft restricting body 16 can be interposed therebetween.
