In addition, blade 16 be arranged under the first datum level 20a of guide portion 20 of interarea 300a (being pasted with the surface of cover strip 306) and side end face 314a and main part 12 and the state of the second datum level 20b butt, with the position of front end face 312 opposed main part 12 in strip length direction of carrier band 300.
Specifically, in the time of upper observation of tape thickness direction (face direction) (w direction of principal axis) of carrier band 300, as shown in Figure 6, the opposed mode of substantial middle in the state that blade 16 tilts with respect to the bandwidth direction (u direction of principal axis) of carrier band 300 with point of a knife 16b and the bandwidth direction of front end 16a and cover strip 300 is arranged at main part 12., the front end 16a of blade 16 be not pasted on base strap 304 cover strip 306 part, the part of the center side in bandwidth direction is opposed in strip length direction.
In addition,, in the time that the side end face side from carrier band 300 is observed along bandwidth direction (u direction of principal axis), as shown in Figure 7, blade 16 is arranged at main part 12 with opposed mode between cover strip 306 and base strap 304 with front end 16a in strip length direction.Specifically, the front end 16a of blade 16 is configured in the tape thickness direction position (w direction of principal axis position) of having left predetermined distance D from the first datum level 20a of the guide portion 20 of the interarea 300a to carrier band 300 (surfaces of cover strip 306 sides), main body 12 that the surperficial 306c of cover strip 306 (not being pasted on the surface of base strap 304) supports along tape thickness direction (w direction of principal axis).The thickness (for example 0.04～0.07mm) of this predetermined distance D and cover strip 306 is roughly the same.
It should be noted that, as shown in Figure 9, the first datum level 20a of guide portion 20 also can replace the surperficial 306c of cover strip 306 is supported, and the part (being formed with the part of transfer port 308) of the surperficial 304a of the base strap 304 that is pasted with cover strip 306 these sides and do not covered by this cover strip 306 is supported as the interarea 300a of carrier band 300.In this case, position in the tape thickness direction (w direction of principal axis) of the front end 16a of blade 16 is the position identical with the surperficial 304a of base strap 304, therefore from the first datum level 20a till the predetermined distance D the tape thickness direction (w direction of principal axis) of the front end 16a of blade 16 is actually zero.
By such blade 16, when carrier band 300 under the first datum level 20a of guide portion 20 and the state of the second datum level 20b butt of interarea 300a (surfaces of cover strip 306 sides) and side end face 314 and the main part 12 of cover strip stripping off device 10 relatively moves with respect to blade 16 along strip length direction (v direction of principal axis), the front end 16a of blade 16 and point of a knife 16b can enter between cover strip 306 and base strap 304 from the front end face of carrier band 300 312 sides along strip length direction.
In addition, in the time that the front end 16a of blade 16 and point of a knife 16b enter into carrier band 300 under the state between cover strip 306 and base strap 304 and relatively move with respect to blade 16 to the bandwidth direction away from second this side of datum level 20b (u direction of principal axis), by the point of a knife 16b of blade 16, cover strip 306 is peeled off from base strap 304 partly.For example,, by a side at the two ends in the bandwidth direction of the cover strip of pasting by bonding agent 310a 306, the part of the side end face 314a side of cover strip 306 is peeled off from base strap 304.
In addition, part in the cover strip 306 of the side end face of carrier band 300 314a side is peeled off from base strap 304, carrier band 300 relatively moves with respect to this blade 16 to the direction away from blade 16, and make blade 16 when leaving between cover strip 306 and base strap 304, consequently, form the clearance G shown in Fig. 8 A and Fig. 8 B.In the region, between the bight 306a and base strap 304 of the cover strip 306 of the side end face of carrier band 300 314a side, being surrounded by the double dot dash line shown in Fig. 8 A, form clearance G.
It should be noted that, before the front end 16a of blade 16 and point of a knife 16b are about to enter between cover strip 306 and base strap 304, as shown in Figure 7, the front end face 312 side parts of carrier band 300 (are not for example clamped along tape thickness direction (w direction of principal axis) by the first datum level 20a of the guide portion 20 of main part 12 and press section 14, end face 14a and 20c in the press section 14 that carrier band 300 is clamped along tape thickness direction (w direction of principal axis) and guide portion 20 strip length direction (v direction of principal axis) separately leave predetermined distance S (for example 2～4mm) from the front end 16a of blade 16 along strip length direction).Its reason is that, if the first datum level 20a and the press section 14 of the front end face of carrier band 300 312 side part directed sections 20 clamp, the front end 16a of blade 16 and point of a knife 16b are difficult for entering between cover strip 306 and base strap 304.In addition, this is the space 24 of accommodating in order to ensure the part of the cover strip 306 to being peeled off by blade 16.It should be noted that, in Fig. 7, end face 14a and 20c in the press section 14 that carrier band 300 is clamped along tape thickness direction and guide portion 20 strip length direction are separately configured in the position in identical strip length direction, but are not limited thereto.For example, can be as shown in Figure 10, make the distance S1 in the strip length direction between the end face 20c of guide portion 20 and the front end 16a of blade 16 be different from the distance S2 in the strip length direction between the end face 14a of press section 14 and the front end 16a of blade 16.For example, will be set as about 2mm apart from S1, will be set as about 1mm apart from S2, and preferably guarantee can supply base strap 304 and the such space of cover strip 306 deflections after blade 16 enters between base strap 304 and cover strip 306.
