Description

Technical Field

[0001] The present invention relates to a storage device for storing a roll body of a carrier tape containing components.

Background Art

[0002] Conventionally, a component mounting device for mounting components on a substrate has been known. As a component supply means in the component mounting device, a tape feeder that conveys a carrier tape containing components and supplies the components to a predetermined component extraction position is frequently used. The supply of the carrier tape to the tape feeder was usually done in a state wound around a reel. In recent years, however, there has been a method in which the reel is eliminated, and the carrier tape is supplied in a state of a roll body wound in a disk shape without a core, and the roll body of the carrier tape is stored in a storage device that can be attached to and detached from the component mounting device (for example, Patent Document 1 below).

[0003] In the storage device described in Patent Document 1, when temporarily holding the leading end of the carrier tape pulled out from the roll body, the feed hole of the carrier tape is fitted into a tape locking projection provided in the storage device and locked. In such a state where the feed hole of the carrier tape is fitted into and held by the tape locking projection, the carrier tape is in a state where the progress in both the pulling-out direction from the roll body and the direction opposite to the pulling-out direction is restricted. When an operator wants to hold the carrier tape, the operator performs an operation of fitting the feed hole of the carrier tape into the tape locking projection.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the operation of the operator inserting the feed holes of the carrier tape into the tape locking projections as described above has a problem of poor workability.

[0006] Therefore, an object of the present invention is to provide a storage device capable of simplifying the operation of temporarily holding a carrier tape pulled out from a stored roll body.

Means for Solving the Problems

[0007] The storage device of the present invention includes a storage unit in which a roll body of a carrier tape storing components is stored, and a holding unit that holds a tip portion of the carrier tape pulled out from the roll body stored in the storage unit. The holding unit includes an insertion portion into which the carrier tape is inserted, and a movable body having a protrusion that fits into a feed hole of the carrier tape inserted into the insertion portion. When the carrier tape inserted into the insertion portion moves in the forward direction, which is the direction in which the carrier tape is pulled out from the roll body, the movable body is positioned at an allowable position where the protrusion is not inserted into the feed hole to allow the movement of the carrier tape. When the carrier tape inserted into the insertion portion attempts to move in the backward direction opposite to the forward direction, the movable body is positioned at a blocking position where the protrusion is inserted into the feed hole to block the movement of the carrier tape.

Effects of the Invention

[0008] According to the present invention, the operation of temporarily holding a carrier tape pulled out from a stored roll body can be simplified.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting apparatus 1 according to an embodiment of the present invention. The component mounting apparatus 1 is an apparatus that carries in a substrate KB by a conveyance conveyor 12 provided on a base 11, takes out a component BH supplied by a component supply unit 13 with a mounting head 14, and mounts it on the substrate KB. In the present embodiment, the conveyance direction of the substrate KB in the component mounting apparatus 1 is defined as the X direction (the left-right direction as viewed from the operator OP), the direction orthogonal to the X direction in the horizontal plane is defined as the Y direction (the front-back direction as viewed from the operator OP), and the vertical direction is defined as the Z direction. Further, among the Y direction (front-back direction), the back side as viewed from the operator OP is referred to as the front, and the front side as viewed from the operator OP is referred to as the back.

[0011] In FIG. 1, the component supply unit 13 includes a carriage 21, a tape feeder 22 as a component supply device attached to the carriage 21, and a storage device 23 (also refer to FIG. 2) attached to the lower part of the carriage 21. A roll body RT of a carrier tape CT is stored in the storage device 23. The roll body RT of the carrier tape CT is a disk-shaped one in which the carrier tape CT is wound in a coreless state.

[0012] As shown in FIG. 3, the carrier tape CT includes a base tape BT and a cover tape TT. Pockets PK that open upward are provided in a row and at equal intervals in the longitudinal direction of the base tape BT, and components BH are stored in each pocket PK. The cover tape TT is attached to the upper surface of the base tape BT and encloses the components BH in the pockets PK. A plurality of feed holes KH are provided in a row and at equal intervals at positions parallel to the row of the pockets PK of the base tape BT.

[0013] The carrier tape CT is pulled out from the roll body RT stored in the storage device 23, and the leading end portion CTS of the pulled-out carrier tape CT is connected to a tape loader 22L provided at the lower rear portion (the end portion on the storage device 23 side) of the tape feeder 22. When the leading end portion CTS of the carrier tape CT is connected, the tape loader 22L pulls out the carrier tape CT from the roll body RT and feeds it into the tape feeder 22. The tape feeder 22 conveys the carrier tape CT fed from the tape loader 22L forward by a sprocket (not shown) provided inside, and supplies the component BH to the component take-out position 22H (FIG. 1) set at the upper front portion.

[0014] In FIG. 1, the mounting head 14 includes a plurality of nozzles 14N extending downward. The mounting head 14 is moved in the horizontal plane (XY plane) direction by a head movement mechanism 14M composed of, for example, an XY movement mechanism or the like. The mounting head 14 can generate a vacuum suction force at the lower end of each nozzle 14N, and adsorbs the component BH supplied by the tape feeder 22 to the component take-out position 22H with the nozzle 14N.

[0015] The mounting head 14 repeatedly executes a mounting cycle consisting of an operation of sucking and picking up the component BH supplied by the tape feeder 22 and a mounting operation of mounting the picked-up component BH on the substrate KB positioned at a predetermined position by the transfer conveyor 12. As a result, a plurality of components BH are successively mounted on the substrate KB, and a mounted substrate is manufactured.

[0016] In such a component mounting apparatus 1, in the present embodiment, the configuration of the storage device 23 is characterized, and the description thereof will be given below. As shown in FIGS. 2 and 4(a) and (b), the storage device 23 includes a storage portion 31 in which the roll body RT of the carrier tape CT is stored, and a holding portion 32 that temporarily holds the leading end portion CTS of the carrier tape CT pulled out from the roll body RT stored in the storage portion 31.

[0017] In FIG. 2, the storage unit 31 includes a storage unit side surface portion 41 formed of two plate-like members 41B arranged at a predetermined interval in the X direction, a storage unit bottom portion 42 provided at the lower part of the storage unit side surface portion 41, and a lock member 43 provided on the storage unit bottom portion 42. The space opened upward and forward by the storage unit side surface portion 41 and the storage unit bottom portion 42 is a storage space 23S for storing the roll body RT of the carrier tape CT.

[0018] The interval between the two plate-like members 41B constituting the storage unit side surface portion 41 is slightly larger than the width direction dimension of the roll body RT to be stored (that is, the carrier tape CT). The interval between the two plate-like members 41B can be changed according to the width direction dimension of the roll body RT to be stored, so that the storage unit 31 can store a plurality of types of roll bodies RT having different width direction dimensions.

[0019] In FIGS. 4(a) and (b), the lock member 43 has a crank shape. The lower end of the lock member 43 is pivotally supported by a shaft member 43J extending in the X direction (the direction in which the two plate-like members 41B face each other) at the front end portion of the storage unit bottom portion 42. Therefore, the lock member 43 is swingable within the YZ plane in which the operation portion 43H moves in the vertical direction about the axis of the shaft member 43J. The upper end portion of the lock member 43 serves as an operation portion 43H for the operator OP to swing the lock member 43.

[0020] Normally, the lock member 43 is located at the "lock position" where the operation portion 43H is located substantially directly above the shaft member 43J (FIG. 4(a)). When the operator OP operates the operation portion 43H of the lock member 43 located at the lock position so as to fall forward of the storage unit 31 (arrow A shown in FIG. 4(b)), it is located at the "unlock position" where the operation portion 43H is located forward of the lock position and is fallen (FIG. 4(b)). A return spring (not shown) for biasing the lock member 43 toward the lock position side is provided in the vicinity of the lower end portion of the lock member 43. Therefore, when the operator OP releases the hand from the state where the lock member 43 is operated to the unlock position side, the lock member 43 automatically returns to the lock position.

[0021] When storing the roll body RT of the carrier tape CT in the storage device 23 (specifically in the storage section 31), the operator OP first operates the lock member 43 located at the locked position to position it at the unlocked position. When the front area of the storage space 23S of the storage section 31 is thus opened, the operator OP puts the roll body RT into the storage section 31 (arrow B shown in Fig. 4(a)), and returns the lock member 43 to the locked position (Fig. 4(b) → Fig. 4(a)). As a result, the front area of the storage space 23S of the storage section 31 is closed by the lock member 43, and the roll body RT is stored (held rotatably) in the storage section 31 (Fig. 4(a) and Fig. 2).

[0022] In Figs. 2 and 4(a) and (b), a gripping portion 44 that can be gripped by the operator OP by hand is formed at the upper part of the storage section 31. By gripping the gripping portion 44, the operator OP can carry the storage section 31 together with the stored roll body RT.

[0023] In Figs. 2 and 4(a) and (b), a plurality of engaging portions 45 for engaging with a part of the cart 21 when attaching the storage device 23 to the cart 21 are provided on the lower surface of the bottom portion 42 of the storage section. The operator OP can attach the storage device 23 to the cart 21 by engaging the engaging portion 45 with the engaged portion 21K of the cart 21 while gripping the gripping portion 44 (Fig. 1).

[0024] In Fig. 5 (an enlarged view of the area AR in Fig. 2) and Fig. 6, the holding portion 32 is provided in the vicinity of the gripping portion 44 of the storage section 31 (specifically, in the vicinity in front of the gripping portion 44). The holding portion 32 includes a base portion 51, an insertion portion forming body 52, an insertion portion forming body biasing spring 53, a movable body 54, and a movable body biasing spring 55.

[0025] In FIGS. 5 and 7, two extending portions 41E extending forward and upward are formed at the upper portions of the two plate-like members 41B constituting the storage portion 31, and the insertion portion forming body 52 is composed of these two extending portions 41E. The insertion portion forming body 52 has two sheet metal members 61 arranged to extend in the vertical direction on both sides in the width direction (X direction) of the base portion 51.

[0026] In FIGS. 7 and 8, upper flange portions 61a extending in directions facing each other are formed at the upper ends of the two sheet metal members 61 respectively. These two upper flange portions 61a are respectively attached to a connecting plate 62 disposed above the base portion 51 by a plurality of connecting plate attachment screws 63.

[0027] In FIG. 8, four through long holes 51N extending in the vertical direction and penetrating in the width direction (X direction) are provided in the base portion 51. Four connecting collars 64 extending through in the width direction of the base portion 51 are inserted into these four through long holes 51N, and both ends of each of these four connecting collars 64 are attached to the two sheet metal members 61 respectively by a plurality of collar attachment screws 65 (FIG. 7). In this way, the two sheet metal members 61 are configured such that their upper parts are connected by one connecting plate 62 and their intermediate parts in the vertical direction are connected by a plurality of connecting collars 64.

[0028] At the lower ends of the two sheet metal members 61, lower flange portions 61b are formed as a pair of flange portions extending in directions facing each other. The upper surfaces 61M of these two lower flange portions 61b face the lower surface 51M of the base portion 51 (FIGS. 5 and 6). Thus, in this embodiment, the two lower flange portions 61b serve as base portion facing portions facing the base portion 51.

[0029] The insertion part forming body 52 is configured to be movable (ascend and descend) in the Z direction with respect to the base part 51 by guiding four connecting collars 64 through four through long holes 51N. When the insertion part forming body 52 ascends and descends with respect to the base part 51, the interval KK (FIG. 6) between the base part 51 and the lower flange part 61b changes accordingly. Specifically, when the insertion part forming body 52 descends with respect to the base part 51, the interval KK becomes wider, and when the insertion part forming body 52 ascends with respect to the base part 51, the interval KK becomes narrower.

[0030] Here, the interval KK at the position where the insertion part forming body 52 ascends most with respect to the base part 51, that is, the minimum value of the interval KK, is set to be slightly larger than the thickness of the carrier tape CT. Therefore, regardless of the position (vertical position) of the insertion part forming body 52 with respect to the base part 51, it is possible to insert the tip part CTS of the carrier tape CT into the region between the base part 51 and the lower flange part 61b. That is, the region between the base part 51 and the lower flange part 61b functions as an insertion part SN into which the tip part CTS of the carrier tape CT is inserted (FIGS. 5 and 6). Of the two openings corresponding to both ends in the longitudinal direction (front-rear direction) of the lower flange part 61b, if the opening closer to the storage part 31 is referred to as the "entrance SNa" and the opening farther from the storage part 31 is referred to as the "exit SNb" (FIG. 5), when inserting the tip part CTS of the carrier tape CT into the insertion part SN, it will be inserted from the entrance SNa toward the exit SNb.

[0031] Thus, in the present embodiment, the insertion part forming body 52 has two lower flange parts 61b which are base part opposing parts arranged to face the lower surface 51M of the base part 51 which forms a part of the storage part 31, and forms an insertion part SN into which the carrier tape CT is inserted between these two lower flange parts 61b and the base part 51.

[0032] In FIGS. 6 and 7, an insertion part forming body biasing spring housing part 71 is provided inside each extension part 41E. The insertion part forming body biasing spring housing part 71 has a bottomed cylindrical inner wall that opens on the upper surface of the extension part 41E and extends in the Z direction. The insertion part forming body biasing spring 53 is provided in a state of being inserted into the insertion part forming body biasing spring housing part 71 from above. The upper end of the insertion part forming body biasing spring 53 protrudes upward from the upper surface of the base part 51 (FIG. 8) and abuts against the lower surface of the connecting plate 62 (FIG. 6).

[0033] In a state where no downward pressing force acts on the upper surface of the insertion part forming body 52 (non-pressing state), the connecting plate 62 is spaced upward from the upper surface of the extension part 41E (FIG. 6). Then, when the upper surface of the insertion part forming body 52 is pressed downward from this non-pressing state, the connecting plate 62 presses and compresses the insertion part forming body biasing spring 53 (that is, against the biasing force of the insertion part forming body biasing spring 53) and approaches the upper surface of the base part 51, and the entire insertion part forming body 52 descends with respect to the base part 51. As a result, the distance KK between the base part 51 and the two lower flange parts 61b increases.

[0034] As described above, in this embodiment, the insertion part forming body biasing spring 53 that functions as an insertion part forming body biasing member for biasing the insertion part forming body 52 in the direction in which the base part facing part (pair of lower flange parts 61b) approaches the base part 51 (arrow C shown in FIG. 6) is provided. When the insertion part forming body 52 is pressed toward the side approaching the base part 51 against the biasing force of the insertion part forming body biasing spring 53, the distance KK between the base part 51 and the base part facing part widens.

[0035] In FIG. 8, a movable body storage space 51P is provided below one of the two extending portions 41E that constitute the base portion 51 (the extending portion 41E located above the feed hole KH of the carrier tape CT inserted into the insertion portion SN in the insertion portion SN). A movable body mounting portion 72 is formed in the movable body storage space 51P (FIGS. 5 and 6). A pivot support member 73 is provided on the movable body mounting portion 72 so as to extend in the width direction (X direction) of the base portion 51, and the movable body 54 is pivotally supported by the pivot support member 73 (FIGS. 6 and 7). Therefore, the movable body 54 is swingable about the axis 73J extending in the X direction of the pivot support member 73.

[0036] In FIGS. 5, 6, and 9(a) and (b), the movable body 54 has a protruding portion 54T that protrudes downward. When the movable body 54 swings about the axis 73J of the pivot support member 73, the movable body 54 swings between a first position (FIG. 9(a)) where the lower end of the protruding portion 54T faces downward and a second position (FIG. 9(b)) where the lower end of the protruding portion 54T faces forward from below.

[0037] In FIGS. 9(a) and (b), a stopper portion 74 is formed at a position in front of the pivot support member 73 in the movable body storage space 51P. The stopper portion 74 is provided at a position where it abuts when the movable body 54 that has swung in the direction from the second position to the first position is located at the first position. Therefore, when the movable body 54 is in the state of being located at the first position with the protruding portion 54T facing downward, the swinging of the protruding portion 54T in the direction of facing forward (the swinging in the direction toward the second position) is allowed, but the swinging in the opposite direction is restricted.

[0038] In FIGS. 6, 7, and 8, at a position above the movable body 54 inside the base portion 51 (specifically, the extension portion 41E on the side where the movable body 54 is provided), a movable body biasing spring housing portion 75 is provided. The movable body biasing spring housing portion 75 has a cylindrical inner wall that opens downward and extends in the Z direction, and the movable body biasing spring 55 is provided in a state of being inserted into the movable body biasing spring housing portion 75 from below. The movable body biasing spring 55 functions as a movable body biasing member that biases the movable body 54 in the direction of positioning it at the first position (arrow D shown in FIGS. 9(a) and (b)). Its upper end abuts against a spring abutting portion 76 formed on the base portion 51 (extension portion 41E on the side where the movable body 54 is provided) from below (FIG. 8), and its lower end abuts against a portion in front of the axis 73J of the upper surface of the movable body 54 from above.

[0039] When the carrier tape CT starts to move in the direction in which the carrier tape CT is pulled out from the roll body RT (the same direction as the direction in which the tip portion CTS of the carrier tape CT exits from the outlet SNb. Arrow E shown in FIG. 12. Hereinafter, referred to as the "forward direction") from the state where the protrusion 54T is fitted into the feed hole KH of the carrier tape CT inserted into the insertion portion SN, the protrusion 54T located at the first position and fitted into the feed hole KH is pushed in the direction in which the carrier tape CT moves (forward direction) by the edge portion FB of the feed hole KH of the carrier tape CT, and the movable body 54 swings around the axis 73J toward the second position (FIG. 12). As a result, the protrusion 54T is detached from the feed hole KH, and the movement of the carrier tape CT in the forward direction is allowed, so the carrier tape CT moves in the forward direction as it is.

[0040] On the other hand, when the leading end portion CTS of the carrier tape CT is inserted into the insertion portion SN and the protruding portion 54T is fitted into the feed hole KH of the carrier tape CT, the movable body 54 is positioned at the first position (FIGS. 10 and 11). In this state, since the swinging of the movable body 54 in the direction of directing the protruding portion 54T rearward is obstructed by the stopper portion 74, even if the carrier tape CT in the inserted state in the insertion portion SN attempts to advance in the direction of exiting from the inlet SNa side, this is restricted by the protruding portion 54T, and the carrier tape CT does not exit from the inlet SNa. When the carrier tape CT starts to advance in the direction of exiting from the outlet SNb from the state where the protruding portion 54T is not fitted into the feed hole KH of the carrier tape CT inserted into the insertion portion SN, after the movable body 54 swings in the direction toward the first position and comes into contact with the stopper portion 74 and stops at the first position, the protruding portion 54T is fitted into the feed hole KH, so that the carrier tape CT still does not exit from the inlet SNa.

[0041] As described above, in this embodiment, the movable body 54 is swingable about the axis 73J extending in the width direction (X direction) of the carrier tape CT inserted into the insertion portion SN. When the carrier tape CT inserted into the insertion portion SN advances in the forward direction in which it is pulled out from the roll body RT, the movable body 54 is positioned at the second position (permissible position) where the protruding portion 54T is not fitted into the feed hole KH to allow the movement of the carrier tape CT. When the carrier tape CT inserted into the insertion portion SN attempts to move in the direction opposite to the forward direction (hereinafter referred to as the "retreat direction"), the movable body 54 is positioned at the first position (blocking position) where the protruding portion 54T is fitted into the feed hole KH to block the movement of the carrier tape CT.

[0042] As described above, since the movable body 54 is biased by the movable-body biasing spring 55 in the direction of being positioned at the first position (blocking position), even when the carrier tape CT is advancing in the forward direction and the protrusion 54T is swinging from the first position (blocking position) to the allowable position (second position), the movable body 54 always tries to return to the blocking position (first position). For this reason, when the carrier tape CT stops advancing, if the protrusion 54T is positioned at a position where it can just fit into the feed hole KH, the protrusion 54T fits into the feed hole KH. Even if it does not fit, if the carrier tape CT then moves in the reverse direction and the movable body 54 is positioned at the first position, the protrusion 54T fits into the feed hole KH.

[0043] When performing a component mounting operation with the component mounting apparatus 1 having such a configuration, first, as a preliminary operation, the operator OP connects the carrier tape CT to the tape feeder 22. In this preliminary operation, first, the roll body RT of the carrier tape CT is stored in the storage device 23. Then, the carrier tape CT is pulled out from the roll body RT, and the leading end portion CTS of the pulled-out carrier tape CT is held by the holding portion 32 of the storage device 23.

[0044] When holding the leading end portion CTS of the carrier tape CT by the holding portion 32, the operator OP inserts the leading end portion CTS of the carrier tape CT into the insertion portion SN of the holding portion 32. When the carrier tape CT is inserted into the insertion portion SN, as shown in FIG. 10, the upper surface of the carrier tape CT faces the lower surface 51M of the base portion 51, and both end portions in the width direction are held by the pair of lower flange portions 61b.

[0045] When the leading end portion CTS of the carrier tape CT is inserted into the insertion portion SN, the leading end portion CTS of the carrier tape CT presses the protrusion 54T of the movable body 54 in the forward direction, so the movable body 54 moves from the first position (blocking position) to the second position (allowable position). For this reason, the carrier tape CT advances in the forward direction within the insertion portion SN without being obstructed by the protrusion 54T of the movable body 54.

[0046] When the operator OP finishes inserting the tip CTS of the carrier tape CT and the protrusion 54T fits into the feed hole KH of the carrier tape CT, the carrier tape CT is held by the holding portion 32. In this state, the carrier tape CT is allowed to move in the forward direction (the direction in which it is pulled out from the roll body RT), but its movement in the backward direction (the direction opposite to the forward direction) is restricted (prevented).

[0047] After the operator OP holds the tip CTS of the carrier tape CT pulled out from the roll body RT in the holding portion 32 as described above, the operator grips the gripping portion 44 of the storage device 23 and attaches it to the carriage 21 in the aforementioned manner. After attaching the storage device 23 to the carriage 21, the operator OP pulls out the carrier tape CT held by the holding portion 32 and inserts the tip CTS of the pulled-out carrier tape CT into the tape loader 22L of the tape feeder 22. This completes the previous operation.

[0048] After the previous operation is completed, it becomes possible to start the component mounting operation by the component mounting device 1. In the component mounting operation, first, the conveyor 12 operates to carry in the substrate KB from the outside and position it at a predetermined working position. When the substrate KB is positioned at the working position by the conveyor 12, the mounting head 14 repeatedly executes mounting turns. One mounting turn consists of an operation of sucking the component BH supplied by the tape feeder 22 to the component taking-out position 22H by the nozzle 14N, and an operation of moving above the substrate KB and mounting the component BH on the substrate KB after sucking the component BH.

[0049] While the mounting head 14 repeatedly executes mounting turns as described above, the tape feeder 22 pulls out the carrier tape CT from the roll body RT stored in the storage device 23. Then, by conveying the pulled-out carrier tape CT forward, the component BH is supplied to the component taking-out position 22H.

[0050] In this embodiment, as shown in FIG. 13, the angle Θ formed between the extending direction of the first portion B1 inserted into the insertion portion SN of the carrier tape CT drawn out from the roll body RT (the extending direction of the line segment L1 shown in FIG. 13) and the extending direction of the second portion B2 which is the portion connecting from the first portion B1 to the side of the roll body RT (the extending direction of the line segment L2 shown in FIG. 13) is set to be 30 degrees or less. By setting the angle Θ formed between the extending direction of the first portion B1 and the extending direction of the second portion B2 to such an angle, even if a part of the carrier tape CT is curved when the carrier tape CT is inserted into the insertion portion SN, the influence of the curvature, for example, when the carrier tape CT is drawn out from the roll body RT by the tape feeder 22, the influence such as the carrier tape CT becoming difficult to pass through the insertion portion SN can be reduced.

[0051] As described above, when the mounting head 14 repeatedly executes the mounting turn and all the components BH to be mounted on the substrate KB are mounted, the transport conveyor 12 operates to carry out the substrate KB to the outside. Thereby, the component mounting operation per sheet of the substrate KB is completed.

[0052] As described above, in the storage device 23 in this embodiment, the holding portion 32 that holds the tip portion CTS of the carrier tape CT drawn out from the roll body RT stored in the storage portion 31 includes an insertion portion SN into which the carrier tape CT is inserted and a movable body 54 having a protrusion 54T that fits into the feed hole KH of the carrier tape CT inserted into the insertion portion SN. Then, when the carrier tape CT inserted into the insertion portion SN moves in the direction (forward direction) in which it is drawn out from the roll body RT, the movable body 54 is positioned at an allowable position (second position) where the protrusion 54T is not fitted into the feed hole KH to allow the movement of the carrier tape CT, and when the carrier tape CT inserted into the insertion portion SN attempts to move in the backward direction opposite to the forward direction, the movable body 54 is positioned at a blocking position (first position) where the protrusion 54T is fitted into the feed hole KH to block the movement of the carrier tape CT.

[0053] Since the storage device 23 in the present embodiment has the above configuration, the carrier tape CT inserted into the insertion portion SN allows the tip portion CTS to move in the forward direction of the insertion portion SN, but movement in the opposite direction is blocked. Therefore, the operator OP can easily hold the tip portion CTS in the holding portion 32 by simply inserting the tip portion of the carrier tape CT into the insertion portion SN.

[0054] Further, even when the carrier tape CT is held by the holding portion 32, the carrier tape CT can be pulled out from the roll body RT. Therefore, when connecting the tip portion CTS of the carrier tape CT to the tape feeder 22, the operator OP does not necessarily have to remove the carrier tape CT from the holding portion 32, and the work of the operator OP can be simplified.

[0055] In the storage device 23 in the present embodiment, when removing the tip portion CTS of the carrier tape CT from the holding portion 32, first, the upper surface of the insertion portion forming body 52 is pressed downward (arrow F shown in FIG. 14). As a result, the entire insertion portion forming body 52 moves below the base portion 51, and the interval KK between the base portion 51 and the lower flange portion 61b of the insertion portion forming body 52 widens (FIG. 14). When the interval KK between the base portion 51 and the lower flange portion 61b widens, the operator OP can move the carrier tape CT downward within the insertion portion SN to disengage the feed hole KH into which the protrusion 54T is inserted from the protrusion 54T (FIG. 15). Therefore, if the carrier tape CT is simply pulled out from the insertion portion SN, the tip portion CTS of the carrier tape CT can be removed from the holding portion 32.

[0056] Further, as described above, after moving the carrier tape CT downward within the insertion portion SN to disengage the feed hole KH into which the protrusion 54T is inserted from the protrusion 54T (FIG. 15), if the carrier tape CT is moved below the insertion portion forming body 52 from between the two lower flange portions 61b, the tip portion CTS of the carrier tape CT can be removed from the holding portion 32 while the tip portion CTS of the carrier tape CT is inserted into the tape loader 22L.

[0057] In this embodiment, as described above, by changing the distance between the two plate-like members 41B, a plurality of types of roll bodies RT having different widthwise dimensions of the roll bodies RT to be stored can be stored in the storage device 23. At this time, according to the changed distance between the two plate-like members 41B (the distance between the two extending portions 41E), the connecting plate 62 and each of the plurality of connecting collars 64 are changed so that the dimension in the X direction corresponds to the distance between the two extending portions 41E (FIGS. 16(a) and (b)). Thereby, even when the widthwise dimension of the roll body RT changes, it becomes possible to hold the tip portion CTS of the carrier tape CT drawn out from the roll body RT.

[0058] As described above, in the storage device 23 according to this embodiment, the carrier tape CT inserted into the insertion portion SN provided in the holding portion 32 is allowed to move in the forward direction, which is the direction of movement in the drawing-out direction from the roll body RT, but the movement in the reverse direction, which is the opposite direction, is blocked. Therefore, when the operator OP wants to temporarily hold the tip portion of the carrier tape CT in the insertion portion SN, the operator only needs to insert the tip portion CTS into the insertion portion SN, and the carrier tape CT can be easily held.

[0059] Further, in the storage device 23 according to this embodiment, even when the carrier tape CT is held, the carrier tape CT can be drawn out from the roll body RT. Therefore, when performing the operation of connecting the tip portion CTS of the carrier tape CT to the tape feeder 22, the operator OP does not necessarily need to remove the carrier tape CT from the holding portion 32, and the operation of the operator OP can be simplified.

[0060] Although the embodiments of the present invention have been described so far, the present invention is not limited to those described above, and various modifications and the like are possible. For example, in the above-described embodiment, the shape of the insertion portion forming body 52 and the like are examples, and any structure may be used as long as it forms an insertion portion SN into which the carrier tape CT is inserted between the base portion 51. Further, in the above-described embodiment, the insertion portion SN is formed on the lower surface 51M side of the base portion 51 by the base portion 51 and a pair of flange portions (lower flange portion 61b) located below the base portion 51. This is because the holding portion 32 is located above the carrier tape CT pulled out from the roll body RT (FIG. 2). By configuring the holding portion 32 to be located below the carrier tape CT pulled out from the roll body RT, the insertion portion may be formed on the upper surface side of the base portion by the base portion and a pair of flange portions located above the base portion.
