That is, inside the cartridge case 130, a tape feed path 196 starting from the tape roll 106 and passing through the tape guide 194 and the platen roller 120 to the tape feed outlet 138 is configured. The printing tape 102 fed out from the tape roll 106 is guided to the platen roller 120 through the tape guide 194, used for printing, and further guided from the platen roller 120 to the tape delivery port 138.

  The tape roll 106 includes a printing tape 102 and a tape core 104 and two circular films 198 attached to both end faces of the roll-shaped printing tape 102. The two circular films 198 prevent the printing tape 102 wound around the tape core 104 from being scattered.

  The tape core 104 has a reel portion 104a around which the printing tape 102 is wound, and a rolling contact portion 104c provided via a plurality of inward ribs 104b inside the reel portion 104a. The core shaft 192 is rotatably supported. A plurality of radial end face grooves 104d are formed on the end face of the rolling contact portion 104c, and the above-described reverse rotation prevention spring 193 is engaged with and disengaged from the end face groove 104d. That is, a longitudinal slit 192a extending in the axial direction is formed at the upper portion of the core shaft portion 192, and the end of the wire rod of the reverse rotation preventing spring 193 protrudes from the longitudinal slit 192a and is engaged with the end face groove 104d of the rolling contact portion 104c. Match.

  When carrying the tape cartridge 100, the reverse rotation preventing spring 193 prevents the reverse rotation of the tape roll 106 (printing tape 102). On the other hand, when the tape cartridge 100 is mounted on the cartridge mounting portion 5, the positioning protrusion 41 compresses the reverse rotation preventing spring 193 (see FIG. 9), and the end of the wire rod is detached from the end surface groove 104d of the rolling contact portion 104c. Then the reverse stop is released. As a result, the printing tape 102 can be fed.

  On the right side of the base in the cartridge case 130, a ribbon accommodating area 200 is formed adjacent to the insertion opening 134. On the right side of the ribbon receiving area 200, a feeding side bearing portion 202 that rotatably supports the ribbon roll 114 (feeding core 112) is provided, and on the left side, a winding side bearing portion that rotatably supports the winding core 116 is provided. 204 are formed integrally with the cartridge case 130, respectively. That is, the feeding side bearing portion 202 and the winding side bearing portion 204 are formed on the upper case 152 and the lower case 150, respectively.

  At the notch portions of the feeding side bearing portion 202 and the take-up side bearing portion 204 formed in the lower case 150, the rotation prevention hook 206 with the tip portion facing the feeding side bearing portion 202 and the take-up side bearing portion 204 is provided. Are integrally formed. One rotation stop hook 206 is engaged with the feeding core 112, and the other rotation stop hook 206 is engaged with the winding core 116 in a rotation stopped state.

  A first ribbon guide 210 that guides the fed ink ribbon 110 to the platen roller 120 is erected integrally with the lower case 150 in the ribbon accommodating area 200 located in the vicinity of the feeding side bearing portion 202. A plurality of second ribbon guides 212 that guide the circumference of the ink ribbon 110 are integrally formed on the outer peripheral side of the opening peripheral wall portion 164.

  That is, inside the cartridge case 130, a ribbon feed path 214 starting from the ribbon roll 114, passing through the first ribbon guide 210, the platen roller 120, and the plurality of second ribbon guides 212 to the winding core 116 is configured. Yes. The ink ribbon 110 fed out from the ribbon roll 114 is guided to the platen roller 120 through the first ribbon guide 210 and used for printing, and further from the platen roller 120 to the opening peripheral wall 164 (a plurality of second ribbon guides). 212) is wound around the winding core 116.

  The ribbon roll 114 includes an ink ribbon 110 and a feeding core 112, and an annular leaf spring 220 that applies a braking load to the feeding core 112 (see FIG. 5B). The leaf spring 220 is formed in a wave shape in the circumferential direction, and is interposed between the top wall portion 156 of the upper case 152 and the feeding core 112 in the axial direction. That is, a rotational braking load is applied to the feeding core 112 by the elastic force of the leaf spring 220. As a result, the back tension is applied to the ink ribbon 110 fed out by the take-up core 116, and the slack is prevented.

  The feeding core 112 is formed in a cylindrical shape, and a plurality of notches 222 are formed in the circumferential direction at the end portion on the lower case 150 side (see FIG. 6). The rotation stop hook 206 is engaged with and disengaged from the plurality of notches 222. The feeding-side bearing portion 202 on the lower case 150 side that supports the feeding core 112 is configured with a circular opening, whereas the feeding-side bearing portion 202 on the upper case 152 side is configured with a cylindrical protruding portion. Yes. And the said leaf | plate spring 220 is mounted | worn with this protrusion part (all refer FIG.5 (b)).

  Similarly, the winding core 116 is formed in a cylindrical shape, and a plurality of notches 224 are formed in the circumferential direction at the end portion on the lower case 150 side. The rotation stop hook 206 is engaged with and disengaged from the plurality of notches 224. A spline groove 226 is formed on the inner peripheral surface of the winding core 116 and engages with the winding drive shaft 47 by spline. Thereby, the rotational force of the winding drive shaft 47 is transmitted to the winding core 116, and the ink ribbon 110 is wound up.

  A platen accommodation area 230 is formed adjacent to the insertion opening 134 on the left side of the base in the cartridge case 130. In the center of the platen accommodation area 230, there are an oval opening lower bearing portion 234 formed in the lower case 150 (see FIG. 6) and an oval opening upper bearing portion 232 formed in the upper case 152 (see FIG. 5B). )) Is provided. The platen roller 120 is supported by the upper bearing portion 232 and the lower bearing portion 234 so as to be rotatable and slightly laterally movable. That is, the platen roller 120 supported by the elliptical upper bearing portion 232 and the lower bearing portion 234 has a home position that engages with the platen drive shaft 45 and a sandwich position that sandwiches the printing tape 102 and contacts the tape guide 194. It is configured to be capable of lateral movement (small movement).

  By the way, the tape cartridge 100 is carried in a state in which the feeding end portion of the printing tape 102 is slightly protruded to the outside from the tape delivery port 138 (see FIG. 1). At that time, if a pressing force or a pulling force acts on the feeding end portion of the printing tape 102 by mistake, the platen roller 120 dragged by this moves to the clamping position. Thereby, the feeding end portion of the printing tape 102 is prevented from being drawn into the cartridge case 130 from the tape delivery port 138.

  The platen roller 120 has a cylindrical roller base 240 and a rubber roller 242 attached to the outer peripheral surface of the roller base 240. The rubber roller 242 has a length corresponding to the print head 21 in the axial direction, and the print head 21 that has moved to the print position sandwiches the print tape 102 and the ink ribbon 110 and contacts the rubber roller 242. A spline groove 244 is formed on the inner peripheral surface of the roller base 240 and engages with the platen drive shaft 45 by spline. Thereby, the rotational force of the platen drive shaft 45 is transmitted to the platen roller 120, and the printing tape 102 (and the ink ribbon 110) is printed and fed.

[Details of Detection Unit and Detected Unit (First Embodiment)]
Next, the structure around the detection unit 51 of the cartridge mounting unit 5 will be described in detail together with the structure around the detected unit 180 of the tape cartridge 100 with reference to FIGS. 7 is a perspective view of the cartridge mounting portion 5, FIG. 8 is a perspective view of the lower case 150 of the tape cartridge 100, and FIG. 9 is a detection of a state in which the tape cartridge 100 is mounted on the cartridge mounting portion 5. FIG. 5 is an enlarged cross-sectional view around a part 51 and a detected part 180.

  As shown in these drawings, the positioning projection 41 (engagement convex portion) of the cartridge mounting portion 5 is composed of a plurality (four in the illustrated example) of conductive contacts 51a (spring pieces). Further, a detection unit 51 is provided. On the other hand, a detected portion 180 is provided on the inner peripheral portion of the core shaft portion 192 of the tape cartridge 100 with respect to the detecting portion 51.

  As shown in FIGS. 7 and 9, the positioning protrusion 41 includes a first convex portion 300 on the distal end side and a second convex portion 302 on the proximal end formed in a large diameter with respect to the first convex portion 300. Have. The first convex portion 300 and the second convex portion 302 are integrally formed (molded), and the first convex portion 300 and the second convex portion 302 are integrally formed (molded) with the mounting base 31. The first convex portion 300 is formed in a cylindrical shape with the upper end closed, and engages with a first concave portion 320 of a core shaft portion 192 described later in a state where the tape cartridge 100 is mounted in the cartridge mounting portion 5. In addition, by this engagement, the first convex portion 300 pushes up (compresses) the above-described reverse-rotation preventing spring 193 whose one end is abutted against the upper case 152 (the top wall portion 156), and reversely rotates the tape roll 106. Release the stop.

  The second convex portion 302 is formed in a cylindrical shape, and is loosely fitted (engaged) with a second concave portion 322 of a core shaft portion 192 described later in a state where the tape cartridge 100 is mounted in the cartridge mounting portion 5. And the detection part 51 comprised by the four conductive contacts 51a is incorporated in the 2nd convex part 302. As shown in FIG. In addition, four slit openings 304 (openings) are formed in the second convex portion 302 so as to be evenly arranged in the circumferential direction. Each slit opening 304 extends in the axial direction, and four conductive contacts 51a protrude from the four slit openings 304 outward in the radial direction.

  As shown in FIGS. 9 and 10, the four conductive contacts 51 a are arranged in a radial manner (equally arranged in the circumferential direction), and the insulating holder 308 ( Is held by a spring honeder). The insulating holder 308 is formed with four holding grooves 308a so as to be evenly arranged in the circumferential direction. Each holding groove 308a extends in the axial direction, and four conductive contacts 51a are held in the four holding grooves 308a. That is, the four conductive contacts 51 a are equally arranged in the circumferential direction of the insulating holder 308 and the second convex portion 302.

  Each conductive contact 51a is made of a conductive metal wire having spring properties, and is fixed to the base portion of the insulating holder 308 and extends along the holding groove 308a (held spring portion). The contactor body 312 (bending spring portion) is bent from the upper end of the straight portion 310 and extends in a “<” shape. And this contactor main body 312 bends, and the bending top part 312a contacts the contact terminal 370 of the to-be-detected part 180 mentioned later. Further, the straight line portion 310 is connected to the detection circuit 52 that detects the attribute information of the binarized tape cartridge 100 (see FIG. 9).

  In a state where the tape cartridge 100 is mounted on the cartridge mounting portion 5, the conductive contact 51 a and the detected portion 180 are in positions facing each other, and the conductive contact 51 a has a spring force toward the detected portion 180. The conductive contact 51a and the detected portion 180 are elastically engaged. The four conductive contacts 51a are arranged in symmetrical positions. Therefore, in the detected part 180 that receives the spring force, the spring forces of the four conductive contacts 51a antagonize and cancel each other. As a result, the tape cartridge 100 receives the spring force of the conductive contact 51a via the detected portion 180, but does not cause a positional shift.

  The conductive contact 51a may be a band-shaped metal material having spring properties. The spring force of the conductive contact 51a can also have a function of fixing (positioning) the tape cartridge 100 in the core shaft portion 192. By fixing the core shaft portion 192 which is the center of gravity of the tape core 104 around which the printing tape 102 having the heaviest weight is wound among the components such as the printing tape 102 and the ink ribbon 110 housed in the tape cartridge 100, The positional deviation of the tape cartridge 100 during the printing operation can be effectively suppressed.

  As shown in FIGS. 8 and 9, the core shaft portion 192 of the tape cartridge 100 includes a first concave portion 320 on the distal end side (back side in the engagement direction) corresponding to the first convex portion 300 and the second concave portion. And a second concave portion 322 on the base end side (front side in the engagement direction) corresponding to the convex portion 302. The first recess 320 and the second recess 322 are integrally formed (molded), and the first recess 320 and the second recess 322 are integrally formed (molded) with the lower case 150 (bottom wall portion 160). Yes. The second recess 322 is formed with a large diameter with respect to the first recess 320.

  The first recess 320 is formed in a cylindrical shape, and the tape core 104 is rotatably engaged with the outer peripheral portion on the base side. Further, the upper end of the first recess 320 reaches the vicinity of the upper case 152 (the top wall portion 156), and the above-described reverse rotation prevention spring 193 is inserted and set in the inner peripheral portion of the first recess 320. (See FIG. 9). In the state where the tape cartridge 100 is mounted in the cartridge mounting portion 5, the first convex portion 300 is engaged with the inner peripheral portion on the base side of the first concave portion 320.

  The second concave portion 322 is formed in a cylindrical shape, and a detected portion 180 constituted by the wiring pattern substrate 324 and a substrate cover 326 that covers the wiring pattern substrate 324 are incorporated in the inner peripheral portion thereof. (See FIG. 9). In this case, the wiring pattern substrate 324 is disposed so as to be sandwiched between the outer peripheral surface of the substrate cover 326 and the inner peripheral surface of the second recess 322. The substrate cover 326 is attached to the second recess 322 in a snap-in manner.

  As shown in FIGS. 9 and 11, the substrate cover 326 is formed in a cylindrical shape, and four hooks 330 for snap-in are formed at the tip thereof. The four hooks 330 are arranged at equal intervals in the circumferential direction. Each hook 330 is integrally formed of a hook body 332 that protrudes outward and a hook spring portion 334 that supports the hook body 332. Further, the hook spring portion 334 is defined by two notch removing portions 336 formed so as to be cut from the tip of the substrate cover 326.

  On the other hand, corresponding to the four hooks 330, four hook receiving holes 340 (hook receiving portions) are formed at the distal end portion (the end portion on the first concave portion 320 side) of the second concave portion 322 (FIG. 8). reference). Each hook receiving hole 340 is formed to have substantially the same width as each hook 330 so that each hook 330 can be positioned in the circumferential direction. When the board cover 326 is inserted into the second recess 322 in a state where the four hooks 330 are aligned with the four hook receiving holes 340, each hook spring portion 334 is bent, and eventually each hook 330 is hook-received. It is locked so as to fall into the hole 340 (snap-in). As a result, the substrate cover 326 is attached to the second recess 322 in a retaining state.

  The substrate cover 326 has four through holes 344 corresponding to the conductive contacts 51a. Each through-hole 344 is formed in a slit shape and extends in the axial direction. Each through hole 344 is disposed at the position of the upper and lower intermediate portions of the substrate cover 326 in the axial direction and at the same position as each hook 330 in the circumferential direction. The conductive contact 51a facing the through hole 344 comes into contact with each contact terminal 370 of the wiring pattern substrate 324 described later (see FIG. 9).

  By the way, when the tape cartridge 100 is mounted on the cartridge mounting portion 5, the positions of the four conductive contacts 51a on the cartridge mounting portion 5 side and the positions of the four contact terminals 370 on the tape cartridge 100 side are the circumference. Must always match in direction. Similarly, the four conductive contacts 51a and the four through holes 344 need to match in the circumferential direction. For this reason, the circumferential positions of the four hooks 330 of the substrate cover 326 are restricted with respect to the four hook receiving holes 340 of the second recess 322.

  Therefore, in the present embodiment, in the circumferential direction, the positions of the four conductive contacts 51a, the positions of the four through holes 344, the positions of the four hooks 330, and the positions of the four hook receiving holes 340, Are arranged so as to match. Although details will be described later, four contact terminals 370 are provided with reference to the positions of the four hooks 330 or the four hook receiving holes 340 (see FIG. 11B).

  The wiring pattern substrate 324 may be partially bonded to the outer peripheral surface of the substrate cover 326 with an adhesive or the like. In such a case, the adhesive layer on the back side is not necessary, and the wiring pattern substrate 324 can be easily attached to the second recess 322 together with the substrate cover 326.

  As shown in FIGS. 9 and 11, the base portion (lower side in the drawing) of the substrate cover 326 has a fitting protrusion 350 projecting annularly outwardly on the outer peripheral surface, and inwardly on the inner peripheral surface. Annular protrusions 352 that project in an annular shape are provided. The lower end (the lower side in the drawing) of the wiring pattern substrate 324 disposed outside the substrate cover 326 is brought into contact with the fitting protrusion 350. Further, the fitting protrusion 350 is fitted to the proximal end portion of the second recess 322 in a state where the substrate cover 326 is attached to the second recess 322. On the other hand, the protrusion dimension of the fitting protrusion 350 corresponds to the thickness of the wiring pattern substrate 324. As a result, the wiring pattern substrate 324 fits in a minute gap between the second recess 322 and the substrate cover 326 generated by the fitting protrusion 350 in a state where the lower end of the wiring pattern board 324 is in contact (positioned) with the fitting protrusion 350. It is like that.

  The annular protrusion 352 is a portion where the four conductive contacts 51a relatively get over while elastically deforming when the tape cartridge 100 is mounted on the cartridge mounting portion 5. In this case, the front end side and the base end side of the annular protrusion 352 are each formed in a chamfered shape. That is, an annular distal-side inclined surface 354 is formed on the distal end side of the annular protrusion 352, and an annular proximal-side inclined surface 356 is formed on the proximal end side.

  The base-side slope 356 smoothly elastically deforms the conductive contacts 51a when the conductive contacts 51a get over relatively. Further, the tip side inclined surface 354 gives a click feeling to the mounting of the tape cartridge 100 and prevents the mounted tape cartridge 100 from being lifted by using the spring force of each conductive contact 51a.

  As shown in FIGS. 9, 11, and 12, the wiring pattern substrate 324 is configured by an FPC (Flexible Printed Circuit) or the like, and is attached to the inner peripheral surface of the second recess 322. In the unfolded wiring pattern substrate 324, the wiring pattern 360 is formed on the front side, and an adhesive layer (not shown) is provided on the back side (see FIG. 12B). For this reason, the wiring pattern substrate 324 is bent in a cylindrical shape so that the front side is inside and the back side is outside, and is attached to the inner peripheral surface of the second recess 322. In actual sticking of the wiring pattern substrate 324 to the second recess 322, the wiring pattern substrate 324 is wound around the outer peripheral surface of the substrate cover 326, and attached to the second recess 322 together with the substrate cover 326 to adhere.

  The length of the wiring pattern substrate 324 is formed slightly shorter than the circumferential length on the inner peripheral surface of the second recess 322 so that the ends of the wiring pattern substrate 324 adhered to the second recess 322 do not overlap each other. (See FIG. 11A). In addition, four notch recesses 362 are formed in a portion of the wiring pattern substrate 324 corresponding to the four hook receiving holes 340 of the second recess 322, in other words, a portion corresponding to the four hooks 330 of the substrate cover 326. ing.

  The four notch recesses 362 are provided so as to escape the four hooks 330, but also function as reference positions for patterning the wiring pattern 360. Although details will be described later, the four contact terminals 370 in the wiring pattern 360 are patterned so as to coincide with the positions of the four hooks 330 (four notch recesses 362) in the circumferential direction (FIG. 12B). )reference).

  The wiring pattern substrate 324 is obtained by printing the wiring pattern 360 with a conductive ink material on a sheet material such as paper or a resin film instead of the FPC, by depositing the wiring pattern 360 on the sheet material, metal foil In other words, a conductive substrate having a conductive wiring pattern 360 and a contact terminal 370 may be provided flexibly on the base material.

  As shown in FIG. 12, the wiring pattern substrate 324 constituting the detected portion 180 is formed with a wiring pattern 360 constituting the attribute information of the tape cartridge 100 on the base substrate 366. The wiring pattern 360 includes four contact terminals 370 including the contact portions 370a with which the four conductive contacts 51a are in contact, and conductive / non-conductive wiring portions 372 connected to the four contact terminals 370. doing. Further, it has a conductive / non-conductive wiring part 372, four individual wiring parts 374 connected to each contact terminal 370, and a common wiring part 376 to which four individual wiring parts 374 are connected. The attribute information of the tape cartridge 100 is configured by the conduction / non-conduction of the individual wiring part 374.

  Each contact terminal 370 and each individual wiring portion 374 are provided at the same position as the above-described notch recess 362 in the circumferential direction. Each contact terminal 370 is patterned in a wide and rectangular shape at a position matching the through hole 344 of the substrate cover 326.

In this case, the four individual wiring portions 374 form 2 ⁴ = 16 bit patterns, that is, 16 types of attribute information, by individual conduction / non-conduction. However, when the detection unit 51 and the detected unit 180 also serve to detect the mounting of the tape cartridge 100, the mounting of the tape cartridge 100 cannot be detected if all of the four individual wiring units 374 are non-conductive patterns. The attribute information is 2 ⁴ −1 = 15 types. In addition, when there is a means for detecting the mounting of the tape cartridge 100, 16 types of attribute information can be assigned to each bit pattern.

  On the other hand, the non-conduction of the embodiment is configured by removing a part of a desired individual wiring portion 374 from the four patterned individual wiring portions 374. That is, in the original wiring pattern 360 (wiring pattern substrate 324), the four individual wiring portions 374 are in a conductive state connected to the four contact terminals 370. In this prototype, a hole 378 is formed in the base substrate 366 by, for example, laser processing or punch punching, and a part of the individual wiring portion 374 is made non-conductive.

  In the detection circuit 52 connected to the four conductive contacts 51a, any one of 15 types of bit patterns (attribute information) is detected, and the type of the tape cartridge 100 is detected.

[Modification of detected part]
Next, a modified example of the wiring pattern substrate 324 (detected portion 180) will be described with reference to FIG. FIG. 13A is a plan view of a wiring pattern substrate 324A according to the first modification, FIG. 13B is a plan view of a wiring pattern substrate 324B according to the second modification, and FIG. It is a top view of wiring pattern board | substrate 324C which concerns on a modification.

  As shown in FIG. 13A, in the wiring pattern substrate 324A of the first modified example, the wiring pattern 360 has no desired individual wiring portion 374 among the four individual wiring portions 374. That is, corresponding to the types (15 types) of the tape cartridge 100, a plurality of types of wiring pattern substrates 324A having different wiring patterns 360 are prepared. Note that a lead (lead wire) corresponding to the individual wiring portion 374 may be used and a necessary lead may be soldered.

  As shown in FIG. 13B, in the wiring pattern substrate 324B of the second modified example, the four individual wiring portions 374 and the common wiring portion 376 are configured by resistance wires. In this case, 15 types of bit patterns (attribute information of the tape cartridge 100) are detected based on differences in resistance values (current values).

  As shown in FIG. 13C, in the wiring pattern substrate 324C of the third modified example, an electronic device 390 (IC chip) is disposed on the wiring pattern 360 on the wiring pattern substrate 324C. In this modification, there is no common wiring part 376 and each individual wiring part 374 is connected to the electronic device 390. The electronic device 390 stores attribute information for each type in the tape cartridge 100. The detection circuit 52 reads the attribute information of the electronic device 390 and detects the type of the tape cartridge 100.

  In particular, in the third modification, the two individual wiring portions 374 are power lines (drive voltage supply lines and ground lines of the electronic device 390), and the other two individual wiring portions 374 are transmission / reception signal lines. Therefore, not only the attribute information is read out, but also necessary information can be written when an EEPROM or a flash memory is used as the electronic device 390. For example, it is possible to overwrite the remaining tape amount of the printing tape 102 from the tape printer 1 side.

  As described above, according to the present embodiment, the detected portion is disposed on the inner peripheral portion of the core shaft portion 192 having a relatively large diameter and a dead space from the viewpoint of preventing the winding tape 102 from curling. Since 180 (wiring pattern substrate 324) is incorporated, an increase in size of the tape cartridge 100 can be suppressed. The wiring pattern substrate 324 can also have a relatively large area. Therefore, even if a small positional deviation occurs in the tape cartridge 100 attached to the cartridge attachment unit 5, the detection performance of the detection unit 51 is not impaired, and the attribute information of the tape cartridge 100 can be detected stably. . Further, when the electronic device 390 is used, attribute information of the tape cartridge 100 having a larger capacity can be provided.

  Needless to say, the number of the conductive contacts 51a and the corresponding contact terminals are arbitrary.

[Second Embodiment]
Next, an embodiment in which the conductive contact 51a is used as a simple spring piece will be described as a second embodiment. In the second embodiment, parts different from the first embodiment will be mainly described.
In this embodiment, the tape detection unit corresponding to the detection unit 51 is provided in the vicinity of the winding drive shaft 47, and the tape detection unit corresponding to the detection unit 180 corresponds to the tape detection unit. It is provided in the cartridge 100 (both not shown).

  As shown in FIG. 14A, the positioning protrusion 41 is provided with four spring pieces 401, and the four spring pieces 401 come into direct contact with the inner peripheral surface of the core shaft portion 192. . Each spring piece 401 has the same form as the above-described conductive contact 51a, and is held by a spring honedder 403 corresponding to the insulating holder 308, as in the first embodiment. However, the spring piece 401 in this case does not require electrical conductivity, and the spring honeder 403 does not require insulation.

  On the other hand, four slit-like position regulating grooves 411 corresponding to the four spring pieces 401 are formed on the inner peripheral surface of the core shaft portion 192. Further, an annular protrusion 352 similar to that of the first embodiment is provided as a separate member on the inner peripheral surface of the core shaft portion 192.
