[0040] (Embodiment 1)

[0041] Figure 1A component loading device 1 with a belt feeder is shown as a component supply device according to Embodiment 1 of the present invention. The component loading device 1 is a device for loading a component BH on a substrate KB, and is provided with a substrate conveying unit 12 on a base 11. The substrate conveying unit 12 conveys the substrate KB in a horizontal direction and positions it at a predetermined working position. Hereinafter, for the sake of convenience of explanation, the conveying direction of the substrate KB conveyed by the substrate conveying unit 12 is set as the X direction, the horizontal direction orthogonal to the X direction is set as the Y direction, and the up and down direction is set as the Z direction. In addition, the direction toward the center side of the base 11 in the Y direction is referred to as the "front", and the direction toward the opposite side thereof is referred to as the "rear".

[0042] A mounting head 13 is provided above the base 11. The mounting head 13 is moved in the horizontal direction by a head moving mechanism (not shown). The mounting head 13 has a plurality of component holding nozzles 14 extending downward.

[0043] exist Figure 1 In the embodiment, a carriage 15 is connected to the end of the base 11 in the Y direction. The carriage 15 includes a feeder base 21 and a reel holding portion 22. A plurality of tape feeders 16 are arranged and mounted on the feeder base 21 in the X direction.

[0044] exist Figure 2 In (a) and (b), the feeder base 21 has a block-shaped platform 31 and a wall 32 provided in front of the platform 31 and extending upward. The upper surface of the platform 31 serves as a feeder support portion 33, and the rear surface of the platform 31 serves as a feeder connection surface 34.

[0045] The table 31 is provided with mounting slots 35 arranged along the X direction for mounting the tape feeder 16. Figure 2 As shown in (a), one assembly slot 35 is composed of a pair of feeder guides 41 arranged in the X direction on the feeder support portion 33, through holes that penetrate the wall portion 32 in the thickness direction (Y direction), that is, two upper and lower positioning holes 42, an assembly hole 44 provided on the feeder connection surface 34, an electric socket 45, and an air socket 46. In this way, in Embodiment 1, the feeder base 21 has a plurality of assembly slots 35 arranged in the X direction.

[0046] The feeder guide 41 is composed of a rail-shaped member arranged in the horizontal direction (X direction, a direction intersecting the conveying direction of the carrier tape in a horizontal plane) and extending in the front-to-back direction (Y direction). The two upper and lower positioning holes 42 are arranged in the Z direction. The assembly hole 44, the electric socket 45 and the air socket 46 are arranged in the Z direction, and the assembly hole 44 is located above the electric socket 45. The air socket 46 is located between the assembly hole 44 and the electric socket 45.

[0047] The reel holding portion 22 rotatably holds a reel RL around which a carrier tape CT carried by the tape feeder 16 is wound. As shown in (a) and (b) of Figure 3 , a plurality of component receiving grooves PK are arranged in a row on the carrier tape CT, and a plurality of feed holes KH are arranged in a row at positions parallel to the row of the component receiving grooves PK.

[0048] In Figure 3 , in (a) and (b), each component receiving groove PK houses one component BH, and a cover tape TT is adhered to the position on the upper surface of the carrier tape CT that covers the component receiving grooves PK. That is, the component BH is in a state of being housed in the carrier tape CT while being covered by the cover tape TT.

[0049] As shown in (a) and (b) of Figure 3 or (a) and (b) of Figure 4 , the cover tape TT has a leading portion SD that extends from the front end ST of the carrier tape CT. The leading portion SD can be in a form in which the front end portion of the cover tape TT protrudes from the front end ST of the carrier tape CT as shown in (a) and (b) of Figure 3 , or can be in a form in which a part of an auxiliary tape HJ adhered to the cover tape TT protrudes from the front end ST of the carrier tape CT as shown in (a) and (b) of Figure 4 .

[0050] In the case of the form in which the front end of the cover tape TT protrudes from the front end ST of the carrier tape CT, the leading portion SD is composed of a part (a portion of length L) of the cover tape TT that extends from the front end ST of the carrier tape CT ((a) of Figure 3 ). In the case of the form using the auxiliary tape HJ, the leading portion SD is composed of a part (a portion of length L) of the auxiliary tape HJ that extends from the front end ST of the carrier tape CT ((b) of Figure 4 ).

[0051] In Figure 5 , (a) and (b) and Figure 6 , the tape feeder 16 includes a main body portion 51 that is detachably assembled to an assembly slot 35 of a feeder base 21. Two positioning pins 52 that protrude forward are provided at the front end portion of the main body portion 51.

[0052] In Figure 5 , (a) and (b) and Figure 6 , a downward extending portion 53 that extends downward is formed at the rear portion of the main body portion 51 of the tape feeder 16. A fixed portion 54, a connector 55, and an air connection portion 56 are respectively provided to protrude forward on the front surface side of the downward extending portion 53.

[0053] In the case where the tape feeder 16 is assembled to the assembly slot 35, the engaged portion 51K provided at the lower portion of the main body 51 ( Figure 6 ) is inserted between the feeder guides 41 that constitute the assembly slot 35 ( Figure 2 from (a) of Figure 2 to (b) of

[0054]

[0055] Figure 6 In Figure 6 , a conveyance path 61 for conveying the carrier tape CT is provided inside the main body 51. The conveyance path 61 has a tape inlet 61A at the rear end of the main body 51 and a tape outlet 61B at the front end of the main body 51. The upper surface of the conveyance path 61 serves as a conveyance surface 61M for supporting and conveying the lower surface of the carrier tape CT (refer to Figure 8 ). That is, in the first embodiment, the conveyance path 61 has a conveyance surface 61M that supports the carrier tape CT from below.

[0056] In Figure 6 , a tape conveyance unit 62 for conveying the carrier tape CT is provided at the upper front side inside the main body 51. The tape conveyance unit 62 includes three sprockets (a guide sprocket 62A, a positioning sprocket 62B, and a discharge sprocket 62C) arranged in order from the rear to the front and a sprocket drive motor 62D.

[0057] In Figure 6 , a plurality of feed pins 62P are provided on the outer circumferential portions of the guide sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C, respectively. These three sprockets rotate in the same direction via a gear mechanism (not shown) by the sprocket drive motor 62D. The direction in which the three sprockets rotate is the direction in which the feed pins 62P located at the highest positions of the respective sprockets move forward. The operation of the sprocket drive motor 62D is controlled by a control unit 63 provided inside the main body 51 ( Figure 6 ).

[0058] The carrier tape CT is pulled out from the reel RL, and its front end side (the side where the aforementioned leading portion SD is formed) is inserted into the conveying path 61 through the carrier tape inlet 61A. The carrier tape CT inserted into the conveying path 61 is conveyed forward (downstream side) by the above three sprockets (the introducing sprocket 62A, the positioning sprocket 62B, and the discharging sprocket 62C) driven by the sprocket driving motor 62D, that is, the carrier tape conveying section 62. At this time, the carrier tape CT is handed over in the order of the introducing sprocket 62A, the positioning sprocket 62B, and the discharging sprocket 62C.

[0059] The carrier tape CT inserted through the carrier tape inlet 61A is conveyed by the carrier tape conveying section 62 toward the downstream side, that is, the carrier tape outlet 61B. The carrier tape CT conveyed toward the downstream side is peeled off the cover tape TT before passing through the component removal opening 16K provided in the front upper part of the main body 51. At the time of passing through the component removal opening 16K, the component BH stored in the carrier tape CT in a state covered by the cover tape TT becomes exposed.

[0060] The component removal opening 16K is provided between the positioning sprocket 62B and the discharging sprocket 62C, and the exposed component BH is intermittently located at the component removal position 16T set inside the component removal opening 16K in sequence. Thus, the mounting head 13 can adsorb and hold the component BH located at the component removal opening 16K (component removal position 16T) through the component holding suction nozzle 14, and take it out (pick up) from the tape feeder 16. In this way, the carrier tape conveying section 62 conveys the carrier tape CT along the conveying path 61 with the leading portion SD of the cover tape TT leading, and makes the component BH located at the component removal position 16T.

[0061] In Figure 6 the aforementioned air connection portion 56 provided in the lower extension 53 of the main body 51 is connected to the air ejection portion 65 provided in the front upper part of the main body 51 through the air pipe 64 provided in the lower extension 53. An air ejection control valve 66 provided in the lower extension 53 is interposed in the air pipe 64.

[0062] When the tape feeder 16 is assembled to the feeder base 21, the air connection portion 56 is connected to the air socket 46 on the feeder base 21 side. In a state where the air connection portion 56 is connected to the air socket 46, by controlling the air ejection control valve 66 by the control section 63, the air supplied from the feeder base 21 side through the air pipe 64 can be ejected from the air ejection portion 65.

[0063] In Figure 6 a Figure 7 shown tape cover 70 is provided on the front upper part of the main body 51. Specifically, as Figure 8 and Figure 9As shown, it is set to cover the part of the conveying path 61 between the positioning sprocket 62B and the discharge sprocket 62C from above. The belt cover 70 is composed of a single plate-like member in Embodiment 1 and is detachable from and attachable to the main body portion 51.

[0064] Figure 10 The state where the belt cover 70 is attached to the main body portion 51 is shown. From Figure 10 it can be seen that the main body portion 51 of the tape feeder 16 includes two tape support portions 51S that extend along the YZ plane and face each other in the X direction. Moreover, the upper edges of the tape support portions 51S form the conveying surface 61M.

[0065] As Figure 10 shown, the belt cover 70 is provided at the front upper portions of the two tape support portions 51S so as to cover a part of the upper edges of the two tape support portions 51S (that is, the conveying surface 61M) from above. As described above, the conveying surface 61M is formed by the upper edges of the two tape support portions 51S, and both end portions of the carrier tape CT are supported from below by the upper edges of the two tape support portions 51S. Therefore, the carrier tape CT can be of not only the type without a downward protruding portion (so-called paper tape type) but also the embossed type having an embossed portion protruding downward.

[0066] In Figure 7 and Figure 10 , the belt cover 70 includes a first tape pressing portion 71 that forms the central part thereof, a second tape pressing portion 72 that forms the part closer to the upstream side than the first tape pressing portion 71, and a third tape pressing portion 73 that forms the part closer to the downstream side than the first tape pressing portion 71. The first tape pressing portion 71 and the second tape pressing portion 72 are connected by a connecting portion 74. A cover tape passage 75 formed by the gap between the first tape pressing portion 71 and the second tape pressing portion 72 is formed at the side of the connecting portion 74 (the side in the width direction of the belt cover 70, that is, the side in the X direction). The above-described component removal opening 16K ( Figure 7 ) is formed in the third tape pressing portion 73.

[0067] Thus, in Embodiment 1, the belt cover 70 is configured to cover the upper surface of the carrier tape CT conveyed by the carrier tape conveying portion 62, and has the component removal opening 16K formed at the component removal position 16T and the cover tape passage 75 formed by the gap formed at a position upstream and away from the component removal opening 16K.

[0068] In Figure 7In [the figure], a protruding piece 71H protruding upstream is formed at the upstream-side end of the first tape pressing portion 71, and the edge of the protruding piece 71H (i.e., the upstream-side edge of the first tape pressing portion 71) serves as a stopper portion 76. As will be described later, the stopper portion 76 functions as a part of a guiding portion 140 that blocks the advancement of the leading portion SD of the cover tape TT provided on the carrier tape CT conveyed by the carrier tape conveying portion 62 and guides the leading portion SD upward (toward the upper surface side of the tape cover 70) from the cover tape passage 75 ( Figure 8 ).

[0069] As described above, the second tape pressing portion 72 is connected to the upstream side of the first tape pressing portion 71 via the connecting portion 74. The downstream-side end of the second tape pressing portion 72 has a linear shape extending in the X direction, and is disposed opposite to the stopper portion 76 with a predetermined gap (cover tape passage 75) therebetween on the upstream side of the stopper portion 76, which is the upstream-side edge of the first tape pressing portion 71.

[0070] In Figure 11 , the downstream-side portion of the second tape pressing portion 72 becomes a contact portion 77 that extends parallel to the conveying surface 61M above the conveying surface 61M. In addition, the portion upstream of the contact portion 77 becomes an inclined portion 78 whose height from the conveying surface 61M gradually increases upstream. The lower surface of the inclined portion 78 is a tapered surface 78M whose distance from the conveying surface 61M becomes narrower from upstream to downstream.

[0071] In Figure 11 , in a state where the carrier tape CT is not inserted into the conveying path 61, the lower surface of the second tape pressing portion 72 does not contact the conveying surface 61M, and a gap with a size of GP is formed between the lower surface of the second tape pressing portion 72 and the conveying surface 61M. Moreover, the size GP of this gap is larger than the thickness of the cover tape TT but smaller than the thickness of the carrier tape CT.

[0072] In Figure 7 , both end portions in the width direction (X direction) of the third tape pressing portion 73 become bent portions 79 that are bent downward. Since the third tape pressing portion 73 is thus formed with bent portions 79 at both end portions in the width direction, the bending rigidity in the vertical direction becomes high and it is difficult to flex, whereby the carrier tape CT near the component removal opening 16K can be firmly pressed against the conveying surface 61M. On the other hand, the first tape pressing portion 71 connected to the upstream side of the third tape pressing portion 73 and further the second tape pressing portion 72 connected to the upstream side of the first tape pressing portion 71 via the connecting portion 74 do not have bent portions like the third tape pressing portion 73, and thus can be easily flexed in the vertical direction.

[0073] In Figure 7 and Figure 10In [the structure], a sprocket avoidance hole 80 is provided on the cover 70 so as to extend in the Y direction. The sprocket avoidance hole 80 is provided to prevent interference between the feed pin 62P of the positioning sprocket 62B and the cover 70.

[0074] In Figure 8 and Figure 9 [the structure], the cover 70 is urged (pressed) from above by three urging portions (front pressing portion 81, middle pressing portion 82, and rear pressing portion 83) provided at the upper front portion of the main body portion 51. Here, the front pressing portion 81 has a function of pressing the portion of the cover 70 on the downstream side of the component removal opening 16K against the carrier tape CT on the conveying surface 61M. The middle pressing portion 82 has a function of pressing the portion between the component removal opening 16K of the cover 70 and the cover tape passage 75 against the carrier tape CT on the conveying surface 61M. The rear pressing portion 83 has a function of pressing the portion of the cover 70 on the upstream side of the cover tape passage 75 against the carrier tape CT on the conveying surface 61M.

[0075] Thus, in Embodiment 1, the entire cover 70 is urged toward the conveying surface 61M side with good balance by the three urging portions (front pressing portion 81, middle pressing portion 82, and rear pressing portion 83). Therefore, the carrier tape CT traveling on the conveying path 61 in the upper front region of the main body portion 51 including the component removal position 16T travels while maintaining a state of being pressed against the conveying surface 61M with an appropriate pressing force. Accordingly, the positioning of the component BH at the component removal position 16T can be accurately performed, and further, the occurrence of a picking error of the component BH by the mounting head 13 can be prevented.

[0076] In Figure 8 and Figure 9 [the structure], the front pressing portion 81 includes a pressing plate 81a as a first swing rod, a pedestal portion 81b, and a first coil spring 81c. The pressing plate 81a extends in the Y direction at the upper front portion of the main body portion 51 (specifically, in a region including above the discharge sprocket 62C and near the carrier tape discharge port 61B). The pedestal portion 81b provided at the downstream end is supported by the main body portion 51 via a support pin 81d extending in the X direction. The first coil spring 81c is provided between the pedestal portion 81b and the main body portion 51 and urges the pedestal portion 81b upward with respect to the main body portion 51.

[0077] As Figure 8 and Figure 9 shown, the upstream end of the pressing plate 81a abuts against the vicinity of the downstream end of the cover 70 from above. Accordingly, the downstream portion (third cover pressing portion 73) of the cover 70 is in a state of being urged (pressed) downward (toward the conveying surface 61M side) by the first coil spring 81c via the pressing plate 81a.

[0078] Thus, in Embodiment 1, the front pressing portion 81 is configured to include: a pressing plate 81a as a first swing rod, which swings about a horizontal axis (support pin 81d) orthogonal to the conveying direction of the carrier tape CT; and a first coil spring 81c, which applies a force to one end of the pressing plate 81a toward the upper surface of the tape cover 70. In a state where the carrier tape CT inserted into the conveying path 61 has not reached below the tape cover 70 (referred to as the "initial state", Figure 8 ), the third tape pressing portion 73 is in a state where its lower surface abuts against the conveying surface 61M.

[0079] In Figure 8 and Figure 9 , the middle pressing portion 82 has a spring holding portion 82a, a torsion spring 82b, and a pressing roller 82c. The spring holding portion 82a is formed of a shaft-like member, and both ends of the shaft-like member are supported by side covers 51P provided on the side surfaces (YZ plane) of the main body portion 51 so as to sandwich the conveying path 61 and extend in the X direction. The side covers 51P constitute the main body portion 51.

[0080] In Figure 8 , Figure 9 and Figure 12 , the torsion spring 82b is held by the spring holding portion 82a by inserting its spiral portion (in the X direction) through the spring holding portion 82a. Among the upstream side extending portion extending upstream and the downstream side extending portion extending downstream, the upstream side extending portion is locked to a pin fixed to the side cover 51P. The pressing roller 82c extends in the X direction, and both ends thereof are supported by the two side covers 51P so as to be movable up and down. The pressing roller 82c can rotate about an axis along the X direction.

[0081] The pressing roller 82c is located at the middle portion of the tape cover 70 (the portion sandwiched by the component removal opening 16K and the cover tape passage 75), and is urged downward by the downstream side extending portion of the torsion spring 82b. Therefore, the middle portion of the tape cover 70 (the first tape pressing portion 71) is in a state of being urged (pressed) downward (toward the conveying surface 61M side) via the pressing roller 82c by the torsion spring 82b (the pressing force F1 shown in Figure 12 ).

[0082] Thus, in Embodiment 1, the middle pressing portion 82 includes: a pressing roller 82c as a roller pin, which can rotate about a horizontal axis (X axis) intersecting the conveying direction of the carrier tape CT; and a torsion spring 82b as an elastic body, which applies a force to the pressing roller 82c toward the upper surface of the tape cover 70. In the initial state where the carrier tape CT inserted into the conveying path 61 has not reached below the tape cover 70, the lower surface of the second tape pressing portion 72 is in a state of abutting against the conveying surface 61M ( Figure 12 ).

[0083] In Figure 8 and Figure 9In this case, the rear pressing portion 83 includes a rear pressing rod 91 serving as a second swing rod and a second coil spring 92. The rear pressing rod 91 extends in the Y direction at the upper front portion of the main body portion 51 (specifically, in the region above the introduction sprocket 62A). As Figure 12 shown, the middle portion of the rear pressing rod 91 in the Y direction is supported by a rod swing shaft 93 extending in the X direction, and has an upstream side extension portion 91a extending from the rod swing shaft 93 toward the upstream side and a downstream side extension portion 91b extending toward the downstream side.

[0084] In Figure 12 this case, the front end portion of the downstream side extension portion 91b bends downward and extends, and a pressing rod front end portion 91c, which is the front end portion of the bent and extended portion, is located above the second tape pressing portion 72. The second coil spring 92 applies a force to the upstream side extension portion 91a of the rear pressing rod 91 upward, that is, in a direction away from the conveying surface 61M. Therefore, the rod front end portion 91c of the rear pressing rod 91 is applied with a force downward, that is, in a direction toward the conveying surface 61M.

[0085] The rotation range of the rear pressing rod 91 is restricted by a pin 94 fixed to the main body portion 51. Therefore, in the initial state where the carrier tape CT has not reached below the contact portion 77 of the second tape pressing portion 72, the rod front end portion 91c is located at a position separated from the upper surface of the upstream side portion (second tape pressing portion 72) of the tape cover 70 by an interval smaller than the thickness dimension of the carrier tape CT, and the rod front end portion 91c is non-contact with the second tape pressing portion 72. When the carrier tape CT reaches below the contact portion 77 of the second tape pressing portion 72 and the second tape pressing portion 72 is lifted by the carrier tape CT, the second tape pressing portion 72 abuts against the rod front end portion 91c. As a result, the second tape pressing portion 72 is in a state of being applied with a force (pressed) downward (toward the carrier tape CT) by the second coil spring 92 via the rear pressing rod 91 (also refer to Figure 24 ).

[0086] In this way, in the first embodiment, the rear pressing portion 83 includes: a rear pressing rod 91 serving as a second swing rod, which swings around a horizontal axis (rod swing shaft 93) orthogonal to the conveying direction of the carrier tape CT; and a second coil spring 92, which applies a force to one end of the rear pressing rod 91 toward the upper surface of the tape cover 70. In addition, the rear pressing portion 83, together with the middle pressing portion 82, presses an upstream side region (first tape pressing portion 71 and second tape pressing portion 72) located upstream of the third tape pressing portion 73, which is a downstream side region of the tape cover 70 where the component removal opening 16K is formed.

[0087] In Figure 8 , Figure 9 and Figure 12In the figure, a cover tape traction part 101 is provided at a position upstream of the component taking-out position 16T. Specifically, it is provided at a position above the tape cover 70 inside the main body part 51. The cover tape traction part 101 has a function of pulling the cover tape TT peeled off from the carrier tape CT upward.

[0088] In Figure 11 and Figure 12 In the figure, the cover tape traction part 101 is composed of a driving roller 101a and a driven roller 101b which has a diameter smaller than that of the driving roller 101a and is located on the downstream side of the driving roller 101a. The driving roller 101a is in contact with the driven roller 101b. When the driving roller 101a rotates counterclockwise in Figure 11 the figure, the driven roller 101b rotates clockwise through the driving roller 101a. The driving roller 101a is driven by a transmission gear mechanism (not shown in the figure) that transmits the power of the transmission sprocket drive motor 62D. Therefore, the driving roller 101a is driven at the same timing as the carrier tape conveying part 62.

[0089] In Figure 8 , Figure 9 and Figure 12 In the figure, a cover tape discharge path 102 is provided at a position upstream of the cover tape traction part 101 inside the main body part 51. The cover tape TT pulled by the cover tape traction part 101 is discharged to the cover tape discharge path 102.

[0090] In Figure 8 , Figure 9 as well as Figure 12 In the figure, a correction part 103 is provided at a position upstream of the tape cover 70 inside the main body part 51 (also refer to Figure 11 ). The correction part 103 has a function of correcting the leading part SD of the cover tape TT of the carrier tape CT inserted into the conveying path 61 from the carrier tape inlet 61A when it bends upward or downward.

[0091] As Figure 10 and Figure 11 shown in the figure, the correction part 103 has a swing member 111 and a concave part 112. The correction part 103 is arranged at a position upstream of the component taking-out position 16T, and has a function of correcting the leading part SD of the cover tape TT into a state facing downstream from the front end ST of the carrier tape CT as the carrier tape CT moves downstream and then returns upstream after being conveyed by the carrier tape conveying part 62.

[0092] In Figure 11 the figure, the swing member 111 has: a base part 111a supported by a rod swing shaft 93 which is the swing shaft of the rear pressing rod 91; and an extension part 111b extending from the base part 111a to the downstream side and having its front end part bent downward. The swing member 111 tends to descend in the direction of the front end side of the extension part 111b due to its own weight ( Figure 11swings in the clockwise direction (in the figure), but its swing is restricted by abutting against a swing restricting member (not shown).

[0093] In a state where the swing caused by the self-weight of the swing member 111 is restricted ( Figure 11 the state shown in the figure, referred to as the "swing restricted state"), the edge of the lower end of the extension portion 111b (swing member edge 111c) is located at a position separated by a certain interval (dimension gp) upward from the conveying surface 61M. And, the dimension gp of this certain interval becomes an interval that is larger than the thickness of the cover tape TT and smaller than the sum of the thickness of the carrier tape CT and the thickness of the cover tape TT. It should be noted that in the first embodiment, the swing member edge 111c is separated from the conveying surface 61M by the dimension gp, but in the case where there is no concern about buckling of the leading portion SD of the cover tape TT, the swing member edge 111c may also be configured to abut against the conveying surface 61M.

[0094] When the swing member edge 111c is pushed up by the carrier tape CT from Figure 11 the swing restricted state shown in the figure, the swing member 111 swings in the direction in which the swing member edge 111c is lifted ( Figure 11 the counterclockwise direction in the figure). Then, in this state, the state where the swing member edge 111c abuts against the upper surface of the carrier tape CT is maintained.

[0095] In Figure 10 and Figure 11 the concave portion 112 has a curved surface 112M formed by a part of the conveying surface 61M being recessed downward. As described above, the conveying surface 61M is formed by the upper edges of two carrier tape supporting portions 51S oppositely arranged in the X direction, so the concave portion 112 (curved surface 112M) is also formed at the upper edges of these two carrier tape supporting portions 51S ( Figure 10 ). The upstream edge of the concave portion 112, which is the upstream edge of each of the upstream and downstream edges of the concave portion 112, i.e., the concave portion edge 112E, is located on the downstream side of the swing member edge 111c ( Figure 11 ).

[0096] Next, the supply operation of the component BH by the tape feeder 16 will be described. When the carrier tape CT is conveyed by the tape feeder 16 to supply the component BH to the component removal position 16T, the operator first, through the above-described steps, based on the state where the leading portion SD extends from the front end of the carrier tape CT, manually inserts the front end ST of the carrier tape CT into the carrier tape inlet 61A. Then, the carrier tape CT is pressed downstream until the feed hole KH of the front end ST of the carrier tape CT engages with the feed pin 62P of the feed sprocket 62A.

[0097] When the carrier tape CT is inserted from the carrier tape inlet 61A so that the feed hole KH near the front end ST of the carrier tape CT engages with the feed pin 62P of the feed sprocket 62A, this situation is detected by a sensor (not shown). After the sensor detects that the feed hole KH of the carrier tape CT has engaged with the feed pin 62P of the feed sprocket 62A, the control unit 63 operates the sprocket drive motor 62D to rotate the three sprockets (the feed sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C). Alternatively, the operator inserts the carrier tape CT from the carrier tape inlet 61A to engage the feed hole KH with the feed pin 62P of the feed sprocket 62A, operates the operation switch of the tape feeder 16 to operate the sprocket drive motor 62D, and rotates the three sprockets. Thus, the carrier tape conveyance unit 62 starts to convey the carrier tape CT, and the carrier tape CT travels downstream on the conveyance surface 61M. It should be noted that at this time, the tape cover 70 is still in the initial state ( Figure 12 ).

[0098] As Figure 13 shown, the front end ST of the carrier tape CT traveling downstream on the conveyance surface 61M passes under the edge 111c of the swing member waiting at a position separated from the conveyance surface 61M, and then passes through the edge 112E of the recess. Then, when the front end ST of the carrier tape CT reaches the position P1 which is a distance D1 ( Figure 13 ) downstream from the position S1 of the edge 112E of the recess by a specified distance, the control unit 63 temporarily stops the operation of the sprocket drive motor 62D (i.e., temporarily stops the travel of the carrier tape CT).

[0099] Here, the above-mentioned specified distance D1 is a distance exceeding the length L of the leading portion SD of the cover tape TT (D1 > L). Therefore, at the time when the rotation of the sprocket drive motor 62D stops (and thus the travel of the carrier tape CT stops), when the leading portion SD of the cover tape TT is bent upward or downward with respect to the carrier tape CT, the front end of the leading portion SD of the cover tape TT, i.e., the leading end SS (also refer to Figure 3 (a) of Figure 4 and Figure 13 ) is located at a position downstream of both the edge 111c of the swing member and the edge 112E of the recess (

[0100] ). It should be noted that when the leading portion SD of the cover tape TT is neither bent upward nor downward with respect to the carrier tape CT, the leading end SS of the leading portion of the cover tape TT enters the space between the lower surface of the contact portion 77 of the conveyance surface 61M and the second tape pressing portion 72 (the space of the gap with the aforementioned dimension GP).

[0100] After temporarily stopping the travel of the carrier tape CT as described above, the control unit 63 rotates the sprocket drive motor 62D in the reverse direction. Thus, the carrier tape CT travels upstream (i.e., moves backward). At the time when the carrier tape CT starts to move backward, when the leading portion SD of the cover tape TT is asFigure 13 When it becomes the upwardly bent state as shown, the front end SS of the leading portion of the cover tape TT abuts against the protruding portion 111b of the swing member 111 and the edge 111c of the swing member from the downstream side. Figure 14 and Figure 15 ).

[0101] After starting the backward movement of the carrier tape CT, when the front end ST of the carrier tape CT reaches the position P2 which is retreated by a predetermined distance D2 from the position S2 of the edge 111c of the swing member to the downstream side, the control unit 63 stops the operation of the sprocket drive motor 62D. Figure 16 ). Here, by setting the above-mentioned predetermined distance D2 to a distance smaller than the length L of the leading portion SD of the cover tape TT and larger than half of the length of the leading portion SD (0.5L < D2 < L), at the time point when the backward movement of the carrier tape CT is stopped, the front end ST of the carrier tape CT is in a state located upstream of the edge 111c of the swing member. In this state, the upwardly bent state of the leading portion SD of the cover tape TT is released, and it becomes a state of extending substantially straight toward the downstream side, that is, a state in which the upward bend of the leading portion SD of the cover tape TT is corrected. Figure 16 ).

[0102] In this way, in Embodiment 1, after the front end ST of the carrier tape CT advances a predetermined distance D1 (to a downstream position that is farther from the concave edge 112E than the length L of the leading portion SD) toward the downstream side of the correction edge (here, the concave edge 112E), a series of operations (hereinafter referred to as "turn-back operation") of moving (retreating) the carrier tape CT to an upstream position where its front end ST is separated from the correction edge (the edge 111c of the swing member) by a predetermined distance D2 that is smaller than the length L of the leading portion SD and larger than half of the length L of the leading portion SD are performed. And, by performing this turn-back operation, even when the leading portion SD of the cover tape TT becomes the upwardly bent state, it can be eliminated.

[0103] In this way, in Embodiment 1, the correction unit 103 includes the swing member 111 disposed above the conveyance surface 61M and having the edge 111c of the swing member as the correction edge at the lower end. In addition, the edge 111c of the swing member 111 waits for the front end of the carrier tape CT to travel from the upstream side at a position separated upward from the conveyance surface 61M.

[0104] In addition, when the leading portion SD of the cover tape TT of the carrier tape CT inserted into the carrier tape inlet 61A becomes the downwardly bent state of being bent downward to the lower side of the carrier tape CT, in the above-mentioned turn-back operation, the front end SS of the leading portion of the cover tape TT is hooked on the upstream edge (the concave edge 112E) of the concave portion 112. Figure 17). Therefore, in a state where the front end ST of the carrier tape CT is located on the upstream side of the edge 111c of the swing member after the return movement is completed ( Figure 16 ), the downward bend of the leading portion SD of the cover tape TT is eliminated, and it becomes a state of extending substantially straight toward the downstream side, that is, a state in which the downward bend of the leading portion SD of the cover tape TT is corrected ( Figure 16 ).

[0105] In this way, in the first embodiment, the concave portion 112 formed on the conveyance surface and the concave edge 112E of the edge on the upstream side of the concave portion 112 become a part of the correction portion 103.

[0106] After the upward or downward bend of the cover tape TT is corrected by the above-described return movement of the carrier tape CT ( Figure 16 ), the control unit 63 operates the sprocket drive motor 62D to rotate the three sprockets in the direction of moving the carrier tape CT downstream. As a result, the front end ST of the carrier tape CT passes through the edge 111c of the swing member downstream, and the front end SS of the leading portion of the cover tape TT in the state of extending downstream enters below the inclined portion 78 of the second tape pressing portion 72 of the tape cover 70 ( Figure 18 ). Further, the front end SS of the leading portion of the cover tape TT enters the space (space of the gap with the dimension GP) between the second tape pressing portion 72 and the conveyance surface 61M ( Figure 19 ).

[0107] Here, when the leading portion SD of the cover tape TT that has been corrected by the correction portion 103 and has become a state of extending downstream (or the leading portion SD of the cover tape TT that has neither been bent upward nor downward with respect to the carrier tape CT since being inserted from the carrier tape insertion port 61A) slightly warps upward before entering the space (space of the gap with the dimension GP) between the contact portion 77 of the second tape pressing portion 72 and the conveyance surface 61M (refer to the leading portion indicated by the reference numeral "SD1" in Figure 18 ), the front end SS of the leading portion travels downstream along the tapered surface 78M of the second tape pressing portion 72. Therefore, the situation where the leading portion SD of the cover tape TT that has been temporarily corrected by the edge 111c of the swing member and the concave edge 112E bends upward again is prevented. In this way, the lower surface (tapered surface 78M) of the inclined portion 78 of the second tape pressing portion 72 becomes an upward bend prevention surface for preventing the upward bend of the cover tape TT.

[0108] In addition, when the leading portion SD of the cover tape TT slightly warps downward before entering the space between the second tape pressing portion 72 and the conveyance surface 61M (refer to Figure 18The leading portion (represented by the reference numeral "SD2" in the drawings) of the cover tape TT advances downstream along the curved surface 112M of the concave portion 112 with the front end SS of the leading portion. Accordingly, the situation where the leading portion SD of the cover tape TT that has been temporarily corrected by the swing member edge 111c and the concave portion edge 112E bends downward again is prevented. In this way, the surface (curved surface 112M) of the concave portion 112 serves as a downward bend prevention surface that prevents the cover tape TT from bending downward to a state where it bends downward with respect to the carrier tape CT.

[0109] The leading portion SD of the cover tape TT that enters the space (a gap space with a dimension of GP) between the contact portion 77 of the second tape pressing portion 72 and the conveyance surface 61M abuts against the stopper portion 76 that abuts against the conveyance surface 61M and is blocked, preventing the leading portion SD from advancing further downstream ( Figure 20 ). And when the carrier tape CT is further conveyed downstream, the front end SS of the leading portion of the cover tape TT protrudes upward through the cover tape passage 75 and protrudes above the second tape pressing portion 72 (i.e., above the tape cover 70) ( Figure 21 ).

[0110] In this way, the stopper portion 76 provided in the first tape pressing portion 71 has the following function: in a state where the first tape pressing portion 71 abuts against the conveyance surface 61M, it blocks the front end SS of the leading portion of the cover tape TT that travels from the upstream side so as not to enter between the first tape pressing portion 71 and the conveyance surface 61M. In the first embodiment, the first tape pressing portion 71 includes a stopper portion 76 that is located downstream of the second tape pressing portion 72 and is disposed on the conveyance surface 61M, and serves as a carrier tape pressing portion that presses the carrier tape CT on the conveyance surface 61M.

[0111] The control unit 63 controls the air ejection control valve 66 at the timing when (or just before) the front end SS of the leading portion of the cover tape TT reaches the cover tape passage 75 of the tape cover 70 as described above, so that the air 107 is ejected upward from the air ejection portion 65 ( Figure 21 ). The air ejection portion 65 is provided at a position where the ejected air 107 passes through the cover tape passage 75 from below.

[0112] If the air 107 is ejected from the air ejection portion 65 at the timing when the front end SS of the leading portion of the cover tape TT reaches the cover tape passage 75, the front end SS of the leading portion of the cover tape TT is guided by the flow of the air 107 ejected from the air ejection portion 65 and protrudes upward through the cover tape passage 75 and protrudes above the tape cover 70. And the carrier tape CT moves upward as it travels downstream and reaches between the driving roller 101a and the driven roller 101b that constitute the cover tape traction portion 101 ( Figure 22 ).

[0113] Thus, in Embodiment 1, the air ejection unit 65 serves as an assisting unit that assists the movement of the leading portion SD of the carrier tape CT in the direction toward the cover tape pulling unit 101 by the flow of air (i.e., gas). Further, in Embodiment 1, the first tape pressing unit 71 as the carrier tape pressing unit including the stopper portion 76 and the air ejection unit 65 as the assisting unit serve as the guiding unit 140 that guides the leading portion SD of the carrier tape CT toward the cover tape pulling unit 101 side.

[0114] The leading end SS of the leading portion of the cover tape TT that reaches between the driving roller 101a and the driven roller 101b is captured by the cover tape pulling unit 101 (by the reverse rotation of the driving roller 101a and the driven roller 101b) and is pulled upward ( Figure 23 ).

[0115] After the leading portion SD of the cover tape TT passes upward through the cover tape passage 75 as described above, the front end ST of the carrier tape CT abuts against the conical surface 78M of the second tape pressing unit 72 ( Figure 21 ). If the carrier tape CT with the front end ST abutting against the conical surface 78M further travels downstream, the second tape pressing unit 72 is pushed upward by the carrier tape CT ( Figure 21 → Figure 22 ).

[0116] The second tape pressing unit 72 pushed upward by the carrier tape CT pulls the first tape pressing unit 71 upward through the connecting portion 74. Therefore, a gap G through which the carrier tape CT can travel is formed between the first tape pressing unit 71 and the conveying surface 61M ( Figure 22 ), and the stopper portion 76, which is the upstream-side edge of the first tape pressing unit 71, also rises from the conveying surface 61M. After the gap G is formed between the first tape pressing unit 71 and the conveying surface 61M, the carrier tape CT travels downstream within this gap ( Figure 22 → Figure 23 ).

[0117] Thus, the second tape pressing unit 72 serves as a contact displacement unit that is displaced by contacting the carrier tape CT, and the connecting portion 74 serves as a transmission unit that transmits the displacement of the second tape pressing unit 72 as the contact displacement unit to the first tape pressing unit 71 to displace the stopper portion 76. Further, the second tape pressing unit 72 as the contact displacement unit and the connecting portion 74 as the transmission unit serve as the height change unit 70T that lifts the stopper portion 76 upward from the conveying surface 61M ( Figure 7 ).

[0118] As described above, when the second tape pressing portion 72 is pushed up by the carrier tape CT, the inclined portion 78 of the second tape pressing portion 72 abuts against the front end portion 91c of the pressing rod of the rear pressing portion 83 from below, and pushes up the front end portion 91c of the pressing rod. As a result, the second coil spring 92 of the rear pressing portion 83 is compressed by the upstream extension portion 91a of the rear pressing rod 91, and applies an upward force to the upstream extension portion 91a with its reaction force. Therefore, the second tape pressing portion 72 (inclined portion 78) is urged downward by the second coil spring 92 via the rear pressing rod 91 (the pressing force F2 shown in Figure 24 ).

[0119] In this way, in the first embodiment, when the carrier tape CT is not in the conveying path 61, the rear pressing rod 91 is non-contact with the tape cover 70, and when the rear pressing portion 83 contacts the tape cover 70 (specifically, the second tape pressing portion 72) that has been displaced upward by the carrier tape CT, it presses the tape cover 70 downward. That is, the rear pressing rod 91 (the second swing rod) is configured to press the tape cover 70 downward when the tape cover 70 is displaced upward by the carrier tape CT.

[0120] When the carrier tape CT travels downstream in the gap formed between the lower surface of the first tape pressing portion 71 and the conveying surface 61M, the cover tape TT extending upward through the cover tape passage 75 is further pulled upward (into the cover tape discharge path 102) by the cover tape pulling portion 101 ( Figure 25 ).

[0121] In this way, in the first embodiment, the cover tape pulling portion 101 is configured to pull the cover tape TT peeled off from the carrier tape CT.

[0122] In the first embodiment, the tape cover 70 and the cover tape pulling portion 101 constitute a cover tape peeling portion 120 ( Figure 8 ). (Also refer to Figure 6 and Figure 11 ). Here, the cover tape peeling portion 120 is a functional portion configured to capture and pull the leading portion SD of the cover tape TT extending downstream from the front end ST of the carrier tape CT, and thereby peel the cover tape TT from the upper surface of the carrier tape CT conveyed downstream by the carrier tape conveying portion 62 at a position downstream of the straightening portion 103 and upstream of the component taking-out position 16T.

[0123] The carrier tape CT from which the cover tape TT has been peeled off by the cover tape peeling portion 120 is conveyed downstream on the conveying path 61 by the carrier tape conveying portion 62, so that the first component receiving groove PK in the carrier tape CT is positioned at the component taking-out position 16T. Thus, the positioning process of the carrier tape CT is completed. The carrier tape conveying portion 62 continuously performs the operation (the positioning process of the carrier tape CT) from the position P2 until the first component receiving groove PK in the carrier tape CT is positioned at the component taking-out position 16T.

[0124] During the positioning process of the carrier tape CT, the cover tape TT is peeled off from the carrier tape CT by the cover tape peeling unit 120. Subsequently, along with the operation of the mounting head 13 of the component mounting device 1 to adsorb and pick up the component BH (pick-up operation), pitch feeding is performed by the carrier tape conveying unit 62, and the component receiving grooves PK are sequentially positioned at the component take-out position 16T (carrier tape positioning operation).

[0125] Thus, in Embodiment 1, the tape feeder 16 as the component supply device is configured to peel the cover tape TT having the leading portion SD protruding from the front end of the carrier tape CT from the carrier tape CT, expose the component BH stored in the carrier tape CT in a state covered by the cover tape TT, and convey the exposed component BH to the component take-out position 16T and supply it to the component mounting device 1.

[0126] When the component mounting device 1 having the tape feeder 16 with the above structure performs a component mounting operation of mounting the component BH on the substrate KB, first, the substrate KB supplied from the outside of the component mounting device 1 is carried in by the substrate conveying unit 12 and positioned at a predetermined operation position. After the substrate KB is positioned at the operation position, each tape feeder 16 supplies the component BH to the component take-out opening 16K, and the mounting head 13 holds and picks up the component BH from the component take-out position 16T of the tape feeder 16 through the component holding nozzle 14. The mounting head 13 that has picked up the component BH from the component take-out position 16T of the tape feeder 16 moves above the substrate KB and mounts the component BH at the target component mounting position determined on the substrate KB. After all the components BH to be mounted on the substrate KB are mounted, the substrate KB is carried out of the component mounting device 1 by the substrate conveying unit 12. Thus, the component mounting operation for one substrate KB is completed.

[0127] As described so far, the tape feeder 16 in Embodiment 1 conveys the carrier tape CT along the conveying path 61 with the leading portion SD of the cover tape TT leading, and returns the carrier tape CT being conveyed downstream upstream, whereby the bending state of the leading portion SD can be corrected by the correcting unit 103. Therefore, even when the leading portion SD of the cover tape TT is bent, it can be reliably caught by the cover tape traction unit 101.

[0128] In addition, the tape feeder 16 in Embodiment 1 includes a guiding portion 140 that guides the leading portion SD of the cover tape TT toward the cover tape traction portion 101. The leading portion SD of the cover tape TT is blocked by the stopper portion 76 and is guided. Therefore, the leading portion SD of the cover tape TT can be reliably guided and captured toward the cover tape traction portion 101. It should be noted that after the leading portion SD of the cover tape TT is captured by the cover tape traction portion 101, the stopper portion 76 is lifted upward by the height changing portion 70T. Therefore, the carrier tape CT can travel on the conveying path 61 without being blocked by the stopper portion 76, and the conveyance of the carrier tape CT is not hindered. The guiding portion 140 in the tape feeder 16 in Embodiment 1 includes a carrier tape pressing portion (first tape pressing portion 71) that presses the carrier tape CT on the conveying surface 61M downstream of the contact displacement portion (second tape pressing portion 72).

[0129] In addition, in the tape feeder 16 of Embodiment 1, for the tape cover 70 having the component extraction opening 16K and the cover tape passage 75, the portion downstream of the component extraction opening 16K is pressed by the front pressing portion 81, the portion sandwiched between the component extraction opening 16K and the cover tape passage 75 is pressed by the middle pressing portion 82, and the portion upstream of the cover tape passage 75 is pressed by the rear pressing portion 83. The entire tape cover 70 is pressed against the conveying path 61 with an appropriate balance. Therefore, the conveyance of the carrier tape CT in the area including the vicinity of the component extraction position 16T can be stably performed, and the extraction accuracy of the component BH can be improved.

[0130] (Embodiment 2)

[0131] Figure 26 A part of the tape feeder in Embodiment 2 is shown. The correction edge of the tape feeder in Embodiment 2 is only the correction edge (the swinging member edge 111c in Embodiment 1) facing the upper surface of the carrier tape CT. Except for this point, it is the same as the tape feeder 16 in Embodiment 1.

[0132] The difference between Embodiment 2 and Embodiment 1 is that the correction portion 103 does not have the concave portion 112. This is a structure that can be adopted in the case where the leading portion SD of the cover tape TT of the carrier tape CT inserted from the carrier tape inlet 61A does not bend downward, that is, when the carrier tape CT is inserted from the carrier tape inlet 61A, the leading portion SD of the cover tape TT is bent upward in advance, that is, the leading portion SD is set in an upwardly bent state and the carrier tape CT is inserted into the carrier tape inlet 61A. In Embodiment 2, since the correction portion 103 also has a correction edge, the same effect as that of the tape feeder 16 in Embodiment 1 can be obtained.

[0133] (Embodiment 3)

[0134] Figure 27Shows a part of the tape feeder in Embodiment 3. The correction edge of the tape feeder in Embodiment 3 is only the edge of the recess 112 formed on the conveyance surface 61M, and except for this point, it is the same as the tape feeder 16 in Embodiment 1.

[0135] The difference between Embodiment 3 and Embodiment 1 is that the correction unit 103 does not have the swing member 111. This is a structure that can be adopted in the case where the leading portion SD of the cover tape TT of the carrier tape CT inserted from the carrier tape inlet 61A does not bend upward, that is, when the carrier tape CT is inserted from the carrier tape inlet 61A, the leading portion SD of the cover tape TT is bent downward in advance, that is, the leading portion SD is set in a downward-bent state and the carrier tape CT is inserted into the carrier tape inlet 61A. In Embodiment 3, since the correction unit 103 also has a correction edge, the same effect as that of the tape feeder 16 in Embodiment 1 can be obtained.

[0136] (Embodiment 4)

[0137] Figure 28 Shows a part of the tape feeder in Embodiment 4. The tape feeder in Embodiment 4 does not have the air ejection portion 65 that appears in Embodiment 1. Instead, a passage 130 that covers the cover tape discharge path 102 and a suction portion 131 that sucks air 107 are provided in the passage 130. Except for this point, it is the same as the tape feeder 16 in Embodiment 1. The guide portion 140 in Embodiment 4 is configured to include a first tape pressing portion 71 and a suction portion 131.

[0138] In Embodiment 4, by using the suction portion 131 provided on the upper side of the conveyance surface 61M to suck the air 107 in the passage 130, it is not necessary to have the air ejection portion 65 in Embodiment 1, and the leading portion SD of the cover tape TT is reliably pulled by the cover tape traction portion 101 through the cover tape passage 75. That is, in Embodiment 4, the suction portion 131, like the aforementioned air ejection portion 65, becomes an auxiliary portion that uses the flow of gas to assist the movement of the leading portion SD in the direction toward the cover tape traction portion 101. The suction portion 131 also functions to guide the front end SS of the leading portion of the cover tape TT toward the cover tape traction portion 101 in the same manner as the air ejection portion 65. Therefore, in Embodiment 4, the same effect as that of the tape feeder 16 in Embodiment 1 can also be obtained.

[0139] (Embodiment 5)

[0140] Figure 29Shows a part of the tape feeder of Embodiment 5. The tape feeder in Embodiment 5 does not have the air ejection portion 65 that appears in Embodiment 1. Instead, a guide member 132 is provided on the downstream side above the cover tape path 75. Except for this point, it is the same as the tape feeder 16 in Embodiment 1. In addition, the stopper portion 76 does not block the travel of the leading portion SD of the cover tape TT, but changes the leading portion SD into a shape that is easy to move upward from the cover tape path 75. The guide portion 140 of Embodiment 5 is configured to include a first tape pressing portion 71 and a guide member 132.

[0141] In Embodiment 5, the leading portion SD in contact with the stopper portion 76 changes its moving direction upward and protrudes above the tape cover 70 through the cover tape path 75. The leading portion SD of the cover tape TT that has moved above the tape cover 70 is guided by the guide member 132 toward the cover tape traction portion 101. Therefore, the capture of the leading portion SD of the cover tape TT by the cover tape traction portion 101 can be reliably performed, and the same effect as that of the tape feeder 16 in Embodiment 1 can be obtained.

[0142] (Embodiment 6)

[0143] Figure 30 Shows a part of the tape feeder of the sixth embodiment. The tape feeder in Embodiment 6 does not have the air ejection portion 65. The shape of the stopper portion 76 of the tape cover 70 (especially the height from the conveyance surface 61M), the dimensions, arrangements, etc. of the driving roller 101a and the driven roller 101b that constitute the cover tape traction portion 101 are different from those in Embodiment 1. Except for this point, it is the same as the tape feeder 16 in Embodiment 1. In addition, the stopper portion 76 does not block the travel of the leading portion SD of the cover tape TT, but changes the leading portion SD into a shape that is easy to move upward from the cover tape path 75. The guide portion 140 of Embodiment 6 is composed only of the first tape pressing portion 71.

[0144] In Embodiment 6, without the need for the aforementioned auxiliary portions (such as the air ejection portion 65, the suction portion 131, the guide member 132, etc.), the leading portion SD of the cover tape TT that protrudes above the tape cover 70 through the cover tape path 75 can be guided to the cover tape traction portion 101. Therefore, in Embodiment 6, the same effect as that of the tape feeder 16 in Embodiment 1 can also be obtained.

[0145] As described above, in the component supply device (tape feeder 16) in Embodiments 1 to 6, the tape cover 70 having the component extraction opening 16K and the cover tape passage 75 is pressed by the front pressing portion 81 at a portion downstream of the component extraction opening 16K, pressed by the middle pressing portion 82 at a portion sandwiched between the component extraction opening 16K and the cover tape passage 75, and pressed by the rear pressing portion 83 at a portion upstream of the cover tape passage 75, so as to be pushed toward the conveyance path 61 with an appropriate balance. Therefore, the conveyance of the carrier tape CT in the area including the vicinity of the component extraction position 16T can be stably performed.

[0146] Thus far, the embodiments of the present invention have been described, but the present invention is not limited to the above, and various modifications and the like can be made. For example, as in Embodiments 1, 2, 4 to 6 described above, when the swing member 111 is in the swing restricted state, waiting for the carrier tape CT to travel with the swing member edge 111c separated from the conveyance path 61, this structure may be replaced with a structure in which the carrier tape CT is waited for to travel with the swing member edge 111c in contact with the conveyance surface 61M. In this case, it is only necessary to configure the conveyance surface 61M to function as the swing restricting member in Embodiment 1.
