Abstract
Description
[Technical Field]
[0001] The present specification relates to a component supply tape holding device and a tape feeder. [Background technology]
[0002] For example, Patent Document 1 below discloses a reel holding device as one form of a component supply tape holding device. In the conventional reel holding device, a movement limiting member that presses the side of the reel is provided on the reel holding side of a slider. One end of the movement limiting member is supported by a pin member to be rotatable, and a magnetic body is attached to the other end. When the movement limiting member rotates around the pin member, the magnetic body at the other end is attracted to a magnet attached to the tip of a center pin and connected to the center pin.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-102561 Summary of the Invention [Problem to be solved by the invention]
[0004] When loading a reel onto a reel holding device, a component may unintentionally fall off the component supply tape wound around the reel. In the conventional reel holding device described above, the fallen component may be attracted to a magnet attached to the tip of the center pin. When the component is attracted to the tip of the center pin, the component becomes caught between the movement limiting member and the center pin, causing the movement limiting member to expand outward, increasing the width of the slider. As a result, when the slider is set on the slider support, it may interfere with other adjacent sliders.
[0005] The present specification aims to provide a reel holding device and a tape feeder that suppress the expansion in the width direction when a reel is attached. [Means for solving the problem]
[0006] This specification discloses a reel holding device comprising a main body, a pressure plate that can be opened and closed relative to the main body so as to press the side of a reel that has component supply tape wound around it and is housed in a reel holder that is perpendicular to the central axis, and a holding portion that attracts and holds the pressure plate by magnetic force when the pressure plate is in a closed state pressing the reel, the holding portion having an attracting portion that attracts the pressure plate and a peripheral portion adjacent to the attracting portion, and at least a part of the peripheral portion generating a magnetic force that is greater than the magnetic force of the attracting portion.
[0007] According to the reel holding device, if a component unintentionally falls off the component supply tape during the reel installation process, the holding portion can preferentially pick up the component in the peripheral area where the magnetic force is strong. In other words, the possibility (or frequency) of the suction portion that adjoins the peripheral area and attracts the pressure plate to pick up the component can be reduced. Therefore, when the suction portion of the holding portion attracts and holds the pressure plate, it is possible to prevent the component that has fallen and been picked up from being caught between the suction portion and the pressure plate. This prevents the reel holding device from expanding in the width direction due to the pressure plate opening when the reel is installed, and prevents interference with other adjacent devices.

[0009] Hereinafter, a reel holding device and a tape feeder equipped with the reel holding device will be described with reference to the drawings. In this embodiment, a production system in which a tape feeder is transported to a component mounting machine by an automatic transport machine will be described as an example.
[0010] 1. Overall configuration of production system 10 As shown in Fig. 1, the production system 10 includes a plurality of component mounting machines 20 arranged in the width direction. The component mounting machines 20 are substrate-related work machines that perform a predetermined task of mounting components P (e.g., electronic components) onto a circuit board K (see Fig. 2). In the production system 10 formed by the plurality of component mounting machines 20, the circuit board K is transported sequentially into each of the component mounting machines 20, and predetermined components are mounted in each of the component mounting machines 20.
[0011] In this embodiment, only the component mounting machine 20 is exemplified as the substrate-related operation machine. However, it is also possible to form the production system 10 by including other devices, such as a printing machine, an inspection machine, a reflow oven, etc., as the substrate-related operation machine.
[0012] In addition, this embodiment illustrates a case where a production system 10 is formed by a plurality of component mounting machines 20. However, it goes without saying that implementation is possible with a single (single) component mounting machine 20 without forming a production system. In addition, in the following description, the X-axis direction is the left-right direction (width direction) of the component mounting machine 20, the Y-axis direction is the front-rear direction (depth direction) of the component mounting machine 20, and the Z-axis direction is the up-down direction (vertical direction) of the component mounting machine 20.
[0013] The production system 10 also includes an automatic conveying device 11 that conveys and detaches a tape feeder 30, which will be described later, for each of the component mounting machines 20. Here, an example of the automatic conveying device 11 is an AGV (Automatic Guided Vehicle), which is an unmanned transport vehicle (unmanned transport robot) that automatically moves back and forth between an automatic warehouse (not shown) and the component mounting machine 20 to convey a predetermined tape feeder 30. Although not shown, the automatic conveying device 11 includes an attachment / detachment mechanism (e.g., a belt conveyor or an articulated robot) for attaching / detaching the tape feeder 30 to / from a component supply device 22 of the component mounting machine 20, which will be described later.
[0014] Furthermore, the production system 10 is equipped with a loader 12 that replenishes components P and changes the setup for the next production run in accordance with the production schedule. The loader 12 is disposed in front of the component mounting machine 20 (more specifically, a component supply device 22, which will be described later) in the Y-axis direction and is movable in the X-axis direction (see FIG. 2). The loader 12 also moves the tape feeder 30 from an upper tier 221a to a lower tier 221b or from the lower tier 221b to the upper tier 221a in a slot 221 of the component supply device 22, which will be described later.
[0015] Specifically, the loader 12 can temporarily store (recover) the tape feeder 30 set in the upper tier 221a of the slot 221, move in the X-axis direction, and then discharge and set the stored (recovered) tape feeder 30 in the lower tier 221b. The loader 12 can also temporarily store (recover) the tape feeder 30 set in the lower tier 221b of the slot 221, move in the X-axis direction, and then discharge and set the stored (recovered) tape feeder 30 in the upper tier 221a. This allows the loader 12 to automatically supply and change the setup of components P. In this embodiment, the loader 12 is movable in the X-axis direction across the adjacent component mounting machine 20 (component supply device 22).
[0016] In addition to the above-mentioned devices, a control device (not shown) for controlling production is also provided in the production system 10. Examples of the control device include a host computer or a buffer connected to the substrate-related operating machine so as to be able to communicate with the substrate-related operating machine.
[0017] 2. Component placement machine 20 As shown schematically in FIG. 2, the component mounting machine 20 mainly includes a board transport device 21, a component supply device 22, a component transfer device 23, a component camera 24, a board camera 25, and a control device 26.
[0018] The board transport device 21 is configured with a belt conveyor or the like, and transports the circuit boards K sequentially in the X-axis direction. The board transport device 21 positions the circuit board K at a predetermined position inside the component mounting machine 20. Then, when the mounting operation on the positioned circuit board K is completed, the board transport device 21 transports the circuit board K outside the component mounting machine 20 (for example, to an adjacent component mounting machine 20).
[0019] The component supply device 22 supplies components P (e.g., electronic components) to be mounted on the circuit board K. The component supply device 22 has a plurality of slots 221 arranged in the X-axis direction, and a tape feeder 30 is removably set in each of the slots 221. Here, in this embodiment, the slot 221 is formed by an upper stage 221a and a lower stage 221b along the Z-axis direction (see FIG. 1). The component supply device 22 feeds and moves a component supply tape 50, which supplies components P (described later), by the tape feeder 30, and supplies the components P to a component supply position Ps (see FIG. 3) provided at the tip side (upper side in FIG. 2) of the tape feeder 30.
[0020] The component transfer device 23 holds the component P supplied to the component supply position Ps and mounts the held component P on the positioned circuit board K. The component transfer device 23 mainly includes a head drive device 231, a movable table 232, and a mounting head 233. The head drive device 231 moves the movable table 232 in the X-axis direction and the Y-axis direction by a linear motion mechanism.
[0021] The mounting head 233 is a holding device that holds the component P, and is detachably mounted on the movable stage 232. A plurality of suction nozzles 235 that can hold the component P are detachably mounted on a nozzle holder 234 mounted on the mounting head 233. The suction nozzles 235 are supported by the mounting head 233 so as to be rotatable about an axis parallel to the Z-axis direction (the up-down direction of the component mounting machine 20) and so as to be movable up and down. The suction nozzles 235 suction-hold the component P that has been supplied to the component supply position Ps, and mount the held component P on the positioned circuit board K.
[0022] The component camera 24 and the board camera 25 are digital imaging devices having imaging elements such as CCD or CMOS. The component camera 24 is fixed to the base of the component mounting machine 20 with its optical axis facing the Z-axis direction, and captures an image of the component P held by the suction nozzle 235 from below. The board camera 25 is fixed to the movable stage 232 with its optical axis facing the Z-axis direction, and captures an image of the circuit board K from above.
[0023] The control device 26 is a computer device whose main components are a CPU, ROM, RAM, and various interfaces, and it comprehensively controls the operation of the component mounting machine 20. Specifically, the control device 26 operates the component mounting machine 20 by executing various programs (not shown). As a result, the component mounting machine 20 performs the mounting operation of the components P, for example, according to a sequence stored in advance.
[0024] 3. Tape Feeder 30 3, tape feeder 30 includes a feeder main body 31, a drive sprocket 32, a manual sprocket 33, a tape presser 34, and a peeling unit 35. Tape feeder 30 also includes a reel holding device 40 that is provided integrally with feeder main body 31 and that holds reel R around which component supply tape 50 is wound.
[0025] In this embodiment, as shown in Fig. 3, reel holding device 40 is provided integrally with feeder main body 31, that is, the "main body" of reel holding device 40 is provided so as to be shared with feeder main body 31. However, reel holding device 40 can also be provided as a separate body, for example, so as to be housed inside feeder main body 31. In this case, reel holding device 40 has a "main body" that is separate from feeder main body 31.
[0026] Here, the component supply tape 50 wound around the reel R will be described. As shown in FIG. 4, the component supply tape 50 includes a base tape 51 and a cover tape 52. The base tape 51 is formed using a flexible material such as paper or resin. On one widthwise side of the base tape 51 (the lower side in FIG. 4), a plurality of cavities 511 capable of accommodating components P are provided at equal intervals along the longitudinal direction of the base tape 51 (the left-right direction in FIG. 4). Furthermore, on the other widthwise side of the base tape 51 (the upper side in FIG. 4), a plurality of feed holes 512 are provided at equal intervals along the longitudinal direction of the base tape 51. The plurality of feed holes 512 mesh with the drive sprocket 32 and the manual sprocket 33.
[0027] The cover tape 52 is formed using a transparent polymer film or the like. As indicated by the dashed line in Fig. 4 , the cover tape 52 covers the upper surface of the base tape 51 and prevents the components P accommodated in the cavities 511 from falling out. The base tape 51 and the cover tape 52 are joined to each other at joining regions 501 and 502 provided on both sides (one side and the other side) of the component supply tape 50 in the width direction, sandwiching the cavities 511 therebetween. The joining regions 501 and 502 are provided on one side of the feed holes 512 in the width direction of the component supply tape 50.
[0028] Feeder body 31 is a thin box-shaped member formed from a transparent or opaque resin plate, metal plate, etc. Although not shown, the side of feeder body 31 is provided so as to be able to open and close, and inside feeder body 31, as shown in Fig. 3, drive sprocket 32, manual sprocket 33, tape pressing unit 34, peeling unit 35, and reel holding device 40 are arranged.
[0029] The drive sprocket 32 is a sprocket that can mesh with the feed holes 512 formed in the base tape 51 of the component supply tape 50, and is rotatably mounted on the feeder body 31. A motor 321 (e.g., a stepping motor) is connected to the drive sprocket 32 via multiple gears (not shown). As a result, the drive sprocket 32 is driven by the motor 321, and by pitch-feeding the component supply tape 50, transports the component P to the component supply position Ps.
[0030] Here, the component supply position Ps is located above the position where the drive sprocket 32 is disposed when viewed from the direction of the rotation axis (X-axis direction) of the drive sprocket 32. This allows the tape feeder 30 to position the meshing position between the component supply tape 50 and the drive sprocket 32 close to the component supply position Ps, thereby enabling the tape feeder 30 to improve the positioning accuracy of the components P transported to the component supply position Ps.
[0031] The manual sprocket 33 is a sprocket that can mesh with the feed holes 512 formed in the base tape 51, and is provided between the reel holding device 40 and the tape presser 34 in the feeding direction of the component supply tape 50. The manual sprocket 33 is used to feed the component supply tape 50 unwound from the reel R to the meshing position with the drive sprocket 32 after a new reel R is attached to the reel holding device 40. For this reason, the manual sprocket 33 is provided with a knob 331 so that it can be manually operated by an operator.
[0032] The tape pressing unit 34 guides the component supply tape 50 drawn out from the reel R so that the component P is transported to the component supply position Ps. The peeling unit 35 peels the cover tape 52 from the base tape 51 before the component P reaches the component supply position Ps, making the component P accommodated in the cavity 511 available for suction by the suction nozzle 235 (see FIG. 2).
[0033] Here, a brief description will be given of the work performed when a new reel R is attached to the reel holding device 40 of the tape feeder 30. After attaching the new reel R to the reel holding device 40, the worker pulls out the component supply tape 50 from the reel R and meshes the feed holes 512 with the manual sprocket 33. The worker then operates the knob 331 to turn the manual sprocket 33. This causes the component supply tape 50 to be fed toward the meshing position with the drive sprocket 32. Then, by meshing the fed component supply tape 50 with the drive sprocket 32, the tape feeder 30 is ready to pitch-feed the component supply tape 50 using the drive sprocket 32.
[0034] For details of the configuration and operation of the tape feeder 30, please refer to the contents of International Publication No. WO2019 / 229993A1, for example.
[0035] 4. Reel holding device 40 3, the reel holding device 40 is provided integrally with the feeder main body 31 as the "main body" and includes a reel holder 41 that accommodates the reel R. The reel holding device 40 also includes a pressing plate 42 that presses the side surface of the reel R accommodated in the reel holder 41 that is perpendicular to the central axis J1.
[0036] The presser plate 42 is provided so as to be openable and closable relative to the feeder main body 31 (main body). As a result, as shown in Fig. 3, in a closed state in which the presser plate 42 holds the reel R, the presser plate 42 covers and holds the side of the reel R so that the top end of the presser plate 42 is above the central axis J1 of the reel R, i.e., above the central axis J1 and a center pin 45 (described later) in the Z-axis direction (the up-down, vertical direction). Furthermore, in an open state in which the presser plate 42 does not hold the reel R, the presser plate 42 allows, for example, the attachment of a new reel R.
[0037] The presser plate 42 is supported by a pair of hinges 43 provided on the feeder main body 31 (main body) below the Z-axis direction (vertical direction), specifically below the central axis J1, and is connected to the feeder main body 31 (main body). This allows the presser plate 42 to rotate about a rotation axis J2 that is located below the central axis J1 of the reel R and perpendicular to the central axis J1. In this embodiment, the rotation axis J2 is located along the Y-axis direction (front-rear direction). Furthermore, the presser plate 42 is locked in the closed state by a locking mechanism 44 that is located above the Z-axis direction and spaced apart from the presser plate 42 in the Y-axis direction.
[0038] As a result, when the presser plate 42 is in a closed state rotated about the hinge 43, it is locked by the locking mechanism 44 and presses down on the side of the reel R. When the presser plate 42 is unlocked by the locking mechanism 44, it rotates about the hinge 43 and enters an open state in which it does not press down on the side of the reel R. When the presser plate 42 is in the open state, it becomes possible to remove the reel R from the reel holder 41 of the reel holding device 40 and to attach the reel R to the reel holder 41.
[0039] The center pin 45 is provided in the X-axis direction (left-right direction) relative to the reel holder 41 so as to be parallel to the center axis J1, more specifically, so as to coincide with the center axis J1 of the reel R. The center pin 45 rotatably supports the reel R by being inserted into a center hole R1 provided corresponding to the center axis J1 of the reel R. Here, when replacing the reel R, the center pin 45 is detachably inserted (attached) into the center hole R1.
[0040] As shown in FIG. 5 , a holding portion 46 is formed at the tip end of the center pin 45. The holding portion 46 has a magnet 47 assembled thereto as described below. As a result, the holding portion 46 attracts and holds the presser plate 42 by magnetic force when the presser plate 42 is in the closed state pressing the reel R. Here, if the presser plate 42 is formed using a magnetic material such as a metal material, the holding portion 46 can directly attract and hold the presser plate 42 in the closed state by magnetic force. On the other hand, if the presser plate 42 is formed using a non-magnetic material such as resin, a magnetic material is provided on the presser plate 42 at a portion facing the holding portion 46 in the closed state. As a result, the holding portion 46 can attract the magnetic material by magnetic force and hold the presser plate 42 in the closed state.
[0041] The holding portion 46 has an adsorption portion 46A corresponding to the end face of the center pin 45 in the axial direction (the central axis J1 of the reel R), and a peripheral portion 46B adjacent to the adsorption portion 46A. In this embodiment, the peripheral portion 46B corresponds to the outer peripheral surface at the tip of the center pin 45 adjacent to the adsorption portion 46A.
[0042] 5, the magnet 47 of this embodiment is formed in a cylindrical shape with a magnetic pole 47N or a magnetic pole 47S arranged at each end. The shape of the magnet 47 is not limited to a cylindrical shape and may be other columnar shapes, such as a rectangular column. In this embodiment, the magnet 47 is inserted and fixed into an assembly hole 461 of the holder 46, which is provided in a direction perpendicular to the axis of the center pin 45 (i.e., the central axis J1 of the reel R), specifically, in the Z-axis direction (the up-down direction, the vertical direction).
[0043] As a result, when the magnet 47 is attached to the holding portion 46 of the center pin 45, the magnetic poles 47N and 47S are arranged so that they coincide with the Z-axis direction, in other words, along a direction different from the central axis J1 of the reel R. That is, the arrangement direction of the magnetic poles 47N and 47S is different from the direction of the central axis J1 of the reel R. As a result, the magnetic poles 47N and 47S are arranged on the outer peripheral surface side of the center pin 45, i.e., in the peripheral portion 46B adjacent to the attracting portion 46A of the holding portion 46. Here, the magnetic poles 47N and 47S are located at positions where the magnetic flux density is greatest, and as a result, they generate the greatest magnetic force.
[0044] 5, when the magnet 47 is attached to the holding portion 46 of the center pin 45, the intermediate portion 47C of the magnetic poles 47N and 47S is positioned on the axis of the center pin 45 (the central axis J1 of the reel R). Therefore, in the magnet 47 attached to the holding portion 46, the intermediate portion 47C, which has a magnetic force relatively weaker than that of the magnetic poles 47N and 47S, is positioned in the attracting portion 46A. Therefore, the attracting portion 46A of the holding portion 46 attracts the presser plate 42 with the magnetic force of the intermediate portion 47C of the magnet 47, more specifically, with a magnetic force relatively weaker than that of the magnetic poles 47N and 47S.
[0045] As a result, in the holding portion 46, the attracting portion 46A provided on the axial end face of the center pin 45 attracts the pressing plate 42 by the magnetic force of the middle portion 47C of the magnet 47. Also, in the holding portion 46, the magnetic poles 47N and 47S of the columnar magnet 47 are arranged in the peripheral portion 46B provided on the outer circumferential surface continuing from the end face of the center pin 45. Therefore, at least a part of the peripheral portion 46B generates a magnetic force greater than the magnetic force of the attracting portion 46A.
[0046] As described above, when a new reel R is attached to the tape feeder 30, for example, the cover tape 52 of the component supply tape 50 may peel off, causing a component P to unintentionally fall into the feeder main body 31 (main body). Alternatively, a component P that has been attached to the outer surface of the cover tape 52 of the component supply tape 50 due to static electricity may fall for some reason. In these cases, in the reel holding device 40 of this embodiment, the fallen component P is preferentially attracted to the peripheral portion 46B of the holding portion 46.
[0047] As described above, the magnetic poles 47N and 47S of the magnet 47 generate the strongest magnetic force. In the holding portion 46, the magnetic poles 47N and 47S of the magnet 47 are arranged in the peripheral portion 46B that corresponds to the outer peripheral surface of the center pin 45. As a result, a stronger magnetic force is always generated in the peripheral portion 46B than in the attracting portion 46A.
[0048] 6, a dropped component P is preferentially attracted to the peripheral portion 46B of the holder 46, i.e., the magnetic poles 47N and 47S that generate a strong magnetic force and are located in the peripheral portion 46B. Therefore, the dropped component P is more likely to be attracted to the peripheral portion 46B, and as a result, the component P is less likely to be attracted to the attraction portion 46A of the holder 46, which has a relatively weaker magnetic force than the peripheral portion 46B.
[0049] 7, if a cylindrical magnet 47 is attached so that its axis coincides with the axis of the center pin 45 (the central axis J1 of the reel R) as in the conventional case, the magnetic pole 47N (or magnetic pole 47S) of the magnet 47 will be located at the end of the center pin 45. In this case, the end of the center pin 45, i.e., the attraction portion 46A that attracts the presser plate 42, will generate a stronger magnetic force due to the magnetic pole 47N (or magnetic pole 47S) of the magnet 47 than the peripheral portion 46B where the intermediate portion 47C is located. Therefore, in this case, the dropped component P will be preferentially attracted to the attraction portion 46A of the holder 46.
[0050] 7, when a dropped component P is adsorbed by the suction portion 46A of the holder 46, the component P becomes caught between the suction portion 46A, i.e., the end of the center pin 45, and the closed presser plate 42. As a result, when the presser plate 42 is closed, the presser plate 42 does not close properly. When the presser plate 42 is in a state where it is more open than normal as shown in FIG. 6, for example, when the loader 26 sets a tape feeder 30 with a new reel R attached in the slot 221, the tape feeder 30, which has become wider in the width direction, may interfere with an adjacent tape feeder 30, for example.
[0051] In contrast, when a dropped component P is preferentially picked up by peripheral portion 46B of holding portion 46, as in the case of holding portion 46 of this embodiment shown in Fig. 6, the possibility of component P getting caught between suction portion 46A, i.e., the end of center pin 45, and closed presser plate 42 is significantly reduced. Therefore, there is little possibility that presser plate 42 will open and widen tape feeder 30, meaning the desired feeder width can be maintained, and as a result, interference with adjacent tape feeders 30 when set in slot 221 can be prevented. Note that component P picked up by peripheral portion 46B of holding portion 46 is removed by an operator, for example, when maintenance is performed on tape feeder 30.
[0052] As can be understood from the above explanation, the reel holding device 40 shares the feeder main body 31 as its main body, and is equipped with a pressure plate 42 that can be opened and closed relative to the feeder main body 31 so as to press the side of the reel R, on which the component supply tape 50 is wound and which is housed in the reel holder 41, that is perpendicular to the central axis J1, and a holding portion 46 that attracts and holds the pressure plate 42 by magnetic force when the pressure plate 42 is in the closed state pressing the reel R, and the holding portion 46 has an attraction portion 46A that attracts the pressure plate 42 and a peripheral portion 46B adjacent to the attraction portion 46A, and a magnetic force greater than the magnetic force of the attraction portion 46A is generated in at least a part of the peripheral portion 46B.
[0053] As a result, in the reel holding device 40, for example, if a component P falls off the component supply tape 50 during the operation of mounting a new reel R, the component P is preferentially attracted to the peripheral portion 46B with a stronger magnetic force. In other words, the possibility (or frequency) of the attraction portion 46A adjacent to the peripheral portion 46B attracting the component P can be reduced.
[0054] This prevents the component P from falling and becoming caught between the suction portion 46A of the holder 46, i.e., the end of the center pin 45, and the presser plate 42 when the suction portion 46A of the holder 46 sucks and holds the presser plate 42. As a result, the width of the tape feeder 30 is prevented from increasing when the presser plate 42 presses the reel R, and the desired feeder width can be maintained. Therefore, for example, when the tape feeder 30 is set in the slot 221 by the loader 26, interference with other adjacent tape feeders 30 can be prevented, which results in good setting workability and prevents damage to the tape feeder 30.
[0055] Here, the prevention of the component P getting caught between the suction portion 46A (center pin 45) and the pressure plate 42 is useful when applied to, for example, a reel loader that automatically sets the reel R. In this case, with the automatic setting of the reel R, for example, the process of an operator checking the state of the center pin 45 can be omitted.
[0056] 5. Variations 5-1. First variant In the above-described embodiment, the columnar (cylindrical) magnet 47 is attached to the holding portion 46 provided at the end of the center pin 45 so that the magnetic poles 47N and 47S are arranged in the vertical direction, which is a direction different from the central axis J1. As a result, the magnetic poles 47N and 47S are arranged in the peripheral portion 46B of the holding portion 46, and as a result, the magnetic force of the peripheral portion 46B is greater than the magnetic force of the attracting portion 46A.
[0057] The number of magnets assembled to the holding portion 46 is not limited to one, and it is also possible to assemble a magnet to each of the attracting portion 46A and the peripheral portion 46B. In a first modified example, as shown in Fig. 8, in the holding portion 46 provided at the end of the center pin 45, a first magnet 48 is arranged in the attracting portion 46A, and a second magnet 49 is arranged in the peripheral portion 46B adjacent to the attracting portion 46A.
[0058] In this case, second magnet 49 is formed, for example, in an annular shape and magnetized so that magnetic pole 49N or magnetic pole 49S is present on each of the outer and inner circumferences. The magnitude of the magnetic force of peripheral portion 46B where second magnet 49 is arranged is set to be greater than the magnitude of the magnetic force of magnetic pole 48N (or magnetic pole 48S) of first magnet 48 assembled to attracting portion 46A. As a result, the same effects as those of the above-described embodiment can be obtained in the first modified example as well.
[0059] 5-2. Second variant In the first modified example described above, the second magnet 49 disposed in the peripheral portion 46B has an annular shape. Instead, in the second modified example, as shown in FIG. 9 , a plurality of plate-shaped second magnets 49 are disposed in the peripheral portion 46B. In this case, the second magnets 49 can be disposed, for example, at equal intervals along the circumferential direction of the center pin 45. Note that, in the second modified example, the magnitude of the magnetic force of the peripheral portion 46B where the plurality of second magnets 49 are disposed is set to be greater than the magnitude of the magnetic force of the magnetic pole 48N (or magnetic pole 48S) of the first magnet 48 assembled to the attracting portion 46A. This allows the second modified example to achieve the same effects as the above-described embodiment.
[0060] 5-3.Third modified example In the embodiment described above, the reel holding device 40 is built into the feeder body 31 of the tape feeder 30. And, because the reel holding device 40 is built into the feeder body 31, the feeder body 31 is used (shared) as the body of the reel holding device 40. However, as described above, the reel holding device 40 is not limited to being provided integrally with the tape feeder 30, but can also be arranged outside the tape feeder 30 and hold one or more reels R, for example, like a reel rack. In this case, the reel holding device 40 may have its own box-shaped or plate-shaped "body," or it may use (share) a body portion arranged outside, such as a reel rack, as in the case of the tape feeder 30.
