[0009] First, definitions of terms used in this specification will be explained. "Overlapping when viewed in a predetermined direction" means that multiple elements are lined up in a predetermined direction, and is synonymous with "overlapping in a predetermined direction." The "predetermined direction" may be, for example, an axial direction, a radial direction, or the direction of gravity. When a drawing shows multiple elements (components, parts, etc.) arranged in a specific direction, it may be assumed that the description in the specification contains a sentence explaining that they overlap when viewed in the specific direction.

[0010] "Not overlapping when viewed in a predetermined direction" and "offset when viewed in a predetermined direction" mean that multiple elements are not lined up in a predetermined direction, and are synonymous with "not overlapping in a predetermined direction" and "offset in a predetermined direction." The "predetermined direction" is, for example, the axial direction, the radial direction, the direction of gravity, etc. If a drawing shows that multiple elements (components, parts, etc.) are not aligned in a specified direction, it may be assumed that the description in the specification contains a sentence explaining that they do not overlap when viewed in the specified direction.

[0011] "When viewed from a predetermined direction, a first element (component, part, etc.) is located between a second element (component, part, etc.) and a third element (component, part, etc.)" means that when observed from a predetermined direction, it can be observed that the first element is located between the second element and the third element. The "predetermined direction" refers to an axial direction, a radial direction, the direction of gravity, etc. For example, if the second element, the first element, and the third element are arranged in that order along the axial direction, it can be said that the first element is located between the second element and the third element when viewed in the radial direction. If the drawings show that the first element is located between the second element and the third element when viewed in a specific direction, it can be considered that the description in the specification contains a sentence explaining that the first element is located between the second element and the third element when viewed in the specific direction.

[0012] The present embodiment will be described below. 1 is a diagram illustrating the cable laying device 1. FIG. 1 is a perspective view of the cable laying device 1. 2 is a diagram illustrating the cable laying device 1. FIG. 2 is a plan view of the cable laying device 1. 3 is a diagram illustrating the cable laying device 1. FIG. 3 is a view taken along the line AA in FIG. 4 is a diagram illustrating the cable laying device 1. FIG. 4 is a rear view of the cable laying device 1. 5 is a diagram illustrating the cable laying device 1. FIG. 5 is a schematic diagram of the cross section taken along line AA in FIG. 6 is a diagram illustrating the cable laying device 1. FIG. 6 is a schematic diagram of the cross section BB in FIG. 1, the magnetic tape 10 is cross-hatched, and in FIG. 2, the magnetic tape 10 and the handle portion 23 are cross-hatched at different pitches. In the following explanation, when explaining the positional relationships of the components of the laying device 1, the XYZ directions (see Figure 1, etc.) are used as the basis. The X direction is the left-right direction of the carriage 2, the Y direction is the front-rear direction of the carriage 2, and the Z direction is roughly along the direction of gravity, but they do not need to be completely parallel or perpendicular. Furthermore, as necessary, the terms "front side" and "rear side" may be used with the Y direction as the basis. Furthermore, the terms "upper side" or "above" and "lower side" or "below" may be used with the Z direction as the basis.

[0013] The installation device 1 installs a guide path for guiding a magnetic detection type automatic guided vehicle. As shown in FIG. 1, the laying device 1 has a carriage 2 carrying a magnetic tape 10 (tape), and a laying section 3 that lays the magnetic tape 10 on a laying surface G. The laying surface G is a plane along the XY direction. The magnetic tape 10 is in the form of a strip with a long overall length in the longitudinal direction. The magnetic tape 10 is wound around the outer periphery of a cylindrical core material S1 and loaded on the carriage 2 in a rolled state. Because the magnetic tape 10 is made of a magnetic material, the magnetic tape 10 wound around the core material S1 maintains its roll shape due to the mutual magnetic force.

[0014] Marking lines Lp indicating a guide path for an automated guided vehicle (not shown) are drawn in advance on the laying surface G. The laying device 1 moves the carriage 2 in a direction (laying direction) along the marking lines Lp, and uses the laying unit 3 to lay the magnetic tape 10 so that it overlaps the marking lines Lp. At this time, the magnetic tape 10 wound around the core material S1 is pulled out in order from the outer periphery.

[0015] The cart 2 is a hand-pushed cart that can be moved by a user pushing it manually. The dolly 2 has a loading platform 20, casters 22, and a handle 23. The loading platform 20 supports the magnetic tape 10 wound around a core material S1 and a transport unit 5, which will be described later. The casters 22 support the loading platform 20 so that it can move relative to the installation surface G. The handle 23 is held by a user when moving the loading platform 20.

[0016] 2, the loading platform 20 is a frame having a substantially rectangular shape in a top view. Specifically, the loading platform 20 has a pair of pillar members 201, 202 arranged along the Y direction, and three connecting pillars 203, 204, 205 extending in the X direction and connecting the pair of pillar members 201, 202. The pair of pillar members 201, 202 are arranged on one side and the other side of the marking line Lp.

[0017] The three connecting posts 203, 204, and 205 are spaced apart in the Y direction. The connecting pillar 203 connects the front ends 201a, 202a of the pair of pillar members 201, 202. The connecting pillar 205 connects the pair of pillar members 201, 202 at a position offset from the rear ends 201b, 202b toward the front ends 201a, 202a. The connecting pillar 204 connects the pair of pillar members 201, 202 between the connecting pillars 203, 205 in the Y direction.

[0018] The caster part 22 is composed of one swivel wheel 221 and two fixed wheels 222L and 222R. The swivel wheel 221 is provided on the connecting pillar 203. The fixed wheel 222L is provided on the pillar member 202. The fixed wheel 222R is provided on the pillar member 201. The free wheel 221 and the two fixed wheels 222L and 222R are provided rotatably around rotation axes X1 and X2 along the X direction.

[0019] The swivel 221 is provided at approximately the center of the connecting post 203 in the X direction. The fixed ring 222L is provided on the pillar member 202 closer to the rear end 202b than the connecting pillar 205. The fixed ring 222R is provided on the pillar member 201 closer to the rear end 201b than the connecting pillar 205. The fixed rings 222L and 222R have the same configuration. In the following explanation, unless a distinction is made between them, the fixed rings 222L and 222R may be simply referred to as the fixed rings 222.

[0020] As shown in FIG. 3, the swivel wheel 221 and the fixed wheel 222R are provided at a portion of the loading platform 20 that faces the laying surface G in the Z direction. As shown in the enlarged area of Fig. 3, the swivel 221 is provided on the connecting post 203 at a portion facing the installation surface G. Note that the enlarged area of Fig. 3 shows the connecting post 203 in cross section.

[0021] The swivel 221 has a wheel 221a that contacts the laying surface G and a fork 221b that supports the wheel 221a so that it can rotate freely around a rotation axis X1. The swivel 221 also has a support tube 221d that supports the fork 221b so that it can rotate around a straight line Lz along the Z direction, and a mount part 221c that fixes the support tube 221d to the connecting column 203.

[0022] The rotation axis X1 of the wheel 221a is offset in the radial direction (left and right direction in the drawing) from the straight line Lz, which is the rotation axis of the fork 221b. Therefore, the wheel 221a swings in the circumferential direction around the straight line Lz in conjunction with the rotation of the fork 221b around the straight line Lz.

[0023] As shown in the enlarged area of Figure 3, the fixed wheel 222R has a wheel 222a that contacts the installation surface G and a fork 222b that supports the wheel 222a so that it can rotate freely around the rotation axis X2. The fixed wheel 222R also has a mount 222c that fixes the fork 222b to the pole member 201. Although not shown, the fixed wheel 222L (see Figure 2) provided on the pole member 202 also has a similar configuration.

[0024] 1, the handle portion 23 is provided on the rear side of the loading platform portion 20 in the Y direction. The handle portion 23 has a pair of support pillars 231, 232 extending upward in the Z direction from the pillar members 201, 202, respectively, and operation portions 233, 234 provided on the upper ends 231a, 232a of the support pillars 231, 232.

[0025] 2, the support pillar 231 is provided on the pillar member 201 closer to the rear end 201b than the connecting pillar 205. The support pillar 232 is provided on the pillar member 202 closer to the rear end 202b than the connecting pillar 205.

[0026] 1, the operating parts 233, 234 have extending walls 235, 236 extending rearward from upper ends 231a, 232a of the support posts 231, 232, and grips 237, 238 extending toward each other from the rear ends of the extending walls 235, 236. A brake lever 85 of the brake mechanism 8, which will be described later, is attached to the grip 237.

[0027] 5, the loading platform 20 is provided with a bottom plate 24 that straddles the connecting posts 204, 205 in the Y direction. The bottom plate 24 is provided between the loading platform 20 and the installation surface G in the Z direction, and is fixed to the connecting posts 204, 205 with bolts B via brackets Bk, Bk, respectively.

[0028] A first support wall 25 that supports the rolled magnetic tape 10 and a second support wall 26 that supports the transport unit 5 (described later) are provided on the upper surface 24a of the bottom plate 24. The first support wall 25 and the second support wall 26 are fixed to the bottom plate 24 with bolts B via a common bracket Bk.

[0029] As shown in FIG. 6, the first support wall 25 and the second support wall 26 are long plates whose longitudinal direction is aligned along the Z direction and whose thickness direction is aligned along the X direction (the front-to-back direction on the paper in the figure).

[0030] The first support wall 25 has a bent portion 253 between an upper end 251 and a lower end 252 in the Z direction. The region of the first support wall 25 from the lower end 252 to the bent portion 253 is oriented perpendicular to the bottom plate 24. The region of the first support wall 25 from the bent portion 253 to the upper end 251 is oriented to approach the handle portion 23 as it moves upward in the Z direction.

[0031] The first support wall 25 has a lower end 252 fixed to the bracket Bk with a bolt B. A case 81 of a brake mechanism 8 (described later) is fixed to an upper end 251 of the first support wall 25 with a bolt B. A bent portion 253 of the first support wall 25 is provided with a tape holder 4 on which a rolled magnetic tape 10 is mounted.

[0032] (Tape holder 4) 7 is a diagram illustrating the tape holder 4. FIG. 7 is a schematic diagram of a cross section taken along line AA in FIG. As shown in FIG. 7, the rolled magnetic tape 10 is supported by a first support wall 25 via a tape holder 4. The tape holder 4 has an inner shaft 41 connected to the first support wall 25, an outer shaft 42 fitted onto the inner shaft 41, a disc plate 43 fitted onto the outer shaft 42, and a bushing 44 pressed into the outer shaft 42.

[0033] The inner shaft 41 has a cylindrical shape surrounding a rotation axis X3 along the X direction. One end 41a of the inner shaft 41 in the direction of the rotation axis X3 abuts against the first support wall 25. A single bolt B passes through the inner periphery of the inner shaft 41 and the first support wall 25 in the direction of the rotation axis X3.

[0034] A nut N is threaded onto the bolt B from the other end 41b side of the inner shaft 41 in the direction of the rotation axis X3. The inner shaft 41 is fixed to the first support wall 25 by the bolt B and the nut N so as not to rotate relative to the first support wall 25.

[0035] The outer shaft 42 has a cylindrical shape and is fitted onto the inner shaft 41 so as to be rotatable relative to the inner shaft 41. The outer shaft 42 is provided with a flange portion 421 on one end 42a side in the direction of the rotation axis X3.

[0036] The disc plate 43 has a ring shape when viewed from the direction of the rotation axis X3. The disc plate 43 is fitted onto the other end 42b of the outer shaft 42. The disc plate 43 is fixed to the flange portion 421 with bolts B while abutting against a side surface 421a of the flange portion 421 from the direction of the rotation axis X3. Therefore, the disc plate 43 rotates integrally with the outer shaft 42 around the rotation axis X3.

[0037] A cylindrical bushing 44 is press-fitted into the outer shaft 42 in an area opposite the flange portion 421 when viewed from the disc plate 43. The core material S1 of the magnetic tape 10 is fitted onto the bushing 44. The roll-shaped magnetic tape 10 rotates integrally with the outer shaft 42 together with the bushing 44.

[0038] The core material S1 is fitted onto the bushing 44 from the other end 42b side of the outer shaft 42 in the direction of the rotation axis X3. At this time, the core material S1 and the rolled magnetic tape 10 abut against the opposing surface 43a of the disk plate 43 in the direction of the rotation axis X3. In this embodiment, the disk plate 43 is made of a magnetic material (for example, a magnetic substance such as iron) that is attracted to the magnetic tape 10. Therefore, the rolled magnetic tape 10 and the disk plate 43 are attracted to each other by magnetic force. This makes it difficult for the rolled magnetic tape 10 to fall off the tape holder 4.

[0039] As shown in the enlarged area of Figure 7, the magnetic tape 10 has a main body 11 made of a magnetic material, an adhesive layer 12 provided on one surface 11a in the thickness direction of the main body 11, and a release paper 13 that protects the adhesive layer 12. The magnetic tape 10 is attached to the tape holder 4 in a state where it is wound around the outer periphery of the core material S1 with the release paper 13 facing outward. Note that the thicknesses of the adhesive layer 12 and the release paper 13 are exaggerated in the enlarged area of Figure 7.

[0040] 6, the second support wall 26 is provided on the rear side of the first support wall 25. The second support wall 26 has a lower end 262 fixed to the bracket Bk with a bolt B, and is inclined toward the handle portion 23 as it approaches the upper end 261. A transport unit 5 is provided on the upper end 261 side of the second support wall 26, which pulls out the rolled magnetic tape 10 from the tape holder 4 side and transports it rearward.

[0041] (Transportation section 5) 6, the conveying section 5 has a first roller 6 provided on the upper end 261 of the second support wall 26, a second roller 7 provided below the first roller 6 on the second support wall 26, and a belt V wound around the first roller 6 and the second roller 7. The rotations of the first roller 6 and the second roller 7 are synchronized via the belt V. The first roller 6 and the second roller 7 constitute a pair of rollers facing each other in the Z direction.

[0042] The first roller 6 and the second roller 7 rotate around rotation axes X4 and X5, respectively, along the X direction. Rotation axes X4 and X5 are located behind rotation axis X3 in the Y direction, and above and below horizontal line HL1 in the Z direction. Horizontal line HL1 is a straight line that passes through the lowest point Pa of the magnetic tape 10 attached to the tape holder 4. Rotation axis X5 is located between rotation axes X3 and X4 in the Y direction.

[0043] (1st Roller 6) 8 is a diagram illustrating the transport unit 5. FIG. 8 is a schematic diagram of the cross section taken along line BB in FIG. As shown in Figure 8, the first roller 6 has an inner shaft 61 connected to the second support wall 26, an outer shaft 62 fitted onto the inner shaft 61, a pulley 63 fitted onto the outer shaft 62, and a bushing 64 pressed into the outer shaft 62.

[0044] The inner shaft 61 has a cylindrical shape surrounding the rotation axis X4. One end 61a of the inner shaft 61 in the direction of the rotation axis X4 abuts against the second support wall 26. A single bolt B passes through the inner periphery of the inner shaft 61 and the second support wall 26 in the direction of the rotation axis X4.

[0045] A nut N is threaded onto the bolt B from the other end 61b side of the inner shaft 61 in the direction of the rotation axis X4. The inner shaft 61 is fixed to the second support wall 26 by the bolt B and the nut N so as not to rotate relative to the second support wall 26.

[0046] The outer shaft 62 has a cylindrical shape and is fitted onto the inner shaft 61 so as to be rotatable relative to the inner shaft 61. The outer shaft 62 is provided with a flange portion 621 on one end 62a side in the direction of the rotation axis X4.

[0047] The pulley 63 has a ring shape when viewed from the direction of the rotation axis X4. The pulley 63 is fitted onto the other end 62b of the outer shaft 62. The pulley 63 is fixed to the flange portion 621 by a bolt B while abutting against a side surface 621a of the flange portion 621 from the direction of the rotation axis X4. Therefore, the pulley 63 rotates integrally with the outer shaft 62 around the rotation axis X4. A pulley groove 63a is formed on the outer periphery of the pulley 63. A belt V is wound around the pulley groove 63a. The belt V may be a known round belt or the like.

[0048] A cylindrical bushing 64 is press-fitted into the outer shaft 62 in a region opposite the flange portion 621 when viewed from the pulley 63. The bushing 64 has a base portion 640 having a smaller diameter than the pulley 63, and a flange portion 641 provided at the other end 640b of the base portion 640.

[0049] The bushing 64 is press-fitted onto the outer shaft 62 with one end 640 a of the base 640 in contact with a side surface 63 b of the pulley 63 . As a result, in the first roller 6, a recess 65 is formed that is recessed radially about the rotation axis X4 in the area surrounded by the side surface 63b of the pulley 63, the outer surface 640c of the base 640 of the bush 64, and the opposing surface 641a of the flange portion 641 facing the pulley 63.

[0050] The magnetic tape 10 pulled out from the tape holder 4 is wound around the recess 65 of the first roller 6. Specifically, as shown in the enlarged area of Figure 8, the release paper 13 of the magnetic tape 10 abuts against the outer peripheral surface 460c of the bushing 64. When a frictional force acts on the recess 65 in the direction in which the magnetic tape 10 is pulled out, the bushing 64 rotates around the rotation axis X4 together with the outer shaft 62 into which it is press-fitted. The pulley 63 fixed to the outer shaft 62 by the bolt B also rotates around the rotation axis X4.

[0051] (Second Roller 7) As shown in FIG. 8, the second roller 7 has the same configuration as the first roller 6. Specifically, the second roller 7 has an inner shaft 71 (shaft) connected to the second support wall 26, an outer shaft 72 (hollow shaft) fitted onto the inner shaft 71, a pulley 73 fitted onto the outer shaft 72, and a bushing 74 pressed into the outer shaft 72.

[0052] The inner shaft 71 has a cylindrical shape surrounding the rotation axis X5. One end 71a of the inner shaft 71 in the direction of the rotation axis X5 abuts against the second support wall 26. A single bolt B passes through the inner periphery of the inner shaft 71 and the second support wall 26 in the direction of the rotation axis X5.

[0053] A nut N is threaded onto the bolt B from the other end 71b side of the inner shaft 71 in the direction of the rotation axis X5. The inner shaft 71 is fixed to the second support wall 26 by the bolt B and the nut N so as not to rotate relative to the second support wall 26.

[0054] The outer shaft 72 has a cylindrical shape and is fitted onto the inner shaft 71 so as to be rotatable relative to the inner shaft 71. The outer shaft 72 has a flange portion 721 on one end 72a side in the direction of the rotation axis X5.

[0055] The pulley 73 has a ring shape when viewed from the direction of the rotation axis X5. The pulley 73 is fitted onto the other end 72b of the outer shaft 72. The pulley 73 is fixed to the flange portion 721 by a bolt B while abutting against a side surface 721a of the flange portion 721 from the direction of the rotation axis X5. Therefore, the pulley 73 rotates integrally with the outer shaft 72 around the rotation axis X5. A pulley groove 73a is formed on the outer periphery of the pulley 73. A belt V is wound around the pulley groove 73a.

[0056] A cylindrical bushing 74 is press-fitted into the outer shaft 72 in an area opposite the flange portion 721 when viewed from the pulley 73. A core material S2 is fitted onto the bushing 74. The core material S2 rotates integrally with the outer shaft 72 together with the bushing 74. The release paper 13 of the magnetic tape 10 is wound around the core material S2.

[0057] As shown in Fig. 6, the belt V is wound around the pulley 63 of the first roller 6 and the pulley 73 of the second roller 7. The winding radius r of the belt V on the first roller 6 and the second roller 7 is the same, and the first roller 6 and the second roller 7 rotate in synchronization via the belt V. The pulley 63 of the first roller 6, the pulley 73 of the second roller 7, and the belt V constitute a rotation transmission mechanism.

[0058] (tension roller) As shown in Fig. 5, the carriage 2 is provided with a tension roller TR behind the conveying section 5 in the Y direction. The tension roller TR is provided on the opposite side of the pressure roller 30, across a tangent line Lq that passes through the bushing 64 of the first roller 6 and the pressure roller 30 (described later). As shown in Fig. 6, the tension roller TR rotates around a rotation axis Xt along the X direction. In the Z direction, the rotation axis Xt is located below a horizontal line HL2 that passes through the rotation axis X6 of the pressure roller 30, and is located between the rotation axes X4 and X6 in the Y direction.

[0059] The tension roller TR is rotatably supported by a roller holder 28. 6, the roller holder 28 has a core member 281 that passes through the tension roller TR at the rotation axis Xt. As shown in FIG. 2, the roller holder 28 has a pair of arms 282, 283 connected to both ends of the core member 281.

[0060] As shown in Fig. 5, one end 282a of the arm 282 is fixed to the bottom plate 24 of the dolly 2 via a bracket Bk with a bolt B. The other end 282b of the arm 282 supports a tension roller TR. The arm 282 runs from the bottom plate 24, bypassing the connecting pillar 205 of the loading platform 20 upward, and is connected to the tension roller TR. In this state, the other end 282b of the arm 282 is positioned lower in the Z direction than the one end 282a.

[0061] As shown in Fig. 6, one end 283a of the arm 283 is fixed to the bottom plate 24 of the dolly 2 via a bracket Bk with a bolt B. The other end 283b of the arm 283 supports a tension roller TR. The arm 283 runs from the bottom plate 24, bypassing the connecting pillar 205 of the loading platform 20 upward, and is connected to the tension roller TR. In this state, the other end 283b of the arm 283 is positioned lower in the Z direction than the one end 283a.

[0062] (Laying section 3) As shown in Fig. 5, the carriage 2 is provided with a laying section 3 behind the tension roller TR, which lays the magnetic tape 10 on the laying surface G. As shown in Fig. 2, the laying section 3 is provided in an area surrounded by the connecting pillar 205, the rear end 201b side of the pillar member 201, and the rear end 202b side of the pillar member 202.

[0063] As shown in FIG. 4, the laying unit 3 has a pressure roller 30 that rotates around a rotation axis X6 along the X direction, and a roller holder 31 that holds the pressure roller 30 rotatably. The width W30 of the pressure roller 30 in the direction of the rotation axis X6 is wider than the width W10 of the magnetic tape 10 (W30>W10). The pressure roller 30 is a cylindrical member that surrounds the rotation axis X6 and has a sufficient weight to press the magnetic tape 10 against the laid surface G.

[0064] The roller holder 31 has a core 32 that passes through the pressure roller 30 at a rotation axis X6, and a pair of arms 33, 34 that are connected to both ends of the core 32. The pair of arms 33, 34 are bar members that are provided across the handle portion 23 of the cart 2 and the pressure roller 30. The pair of arms 33, 34 have symmetrical shapes with the pressure roller 30 in between.

[0065] The arms 33 and 34 are connected to each other from the opposing surfaces 231b and 232b of the support posts 231 and 232 of the handle portion 23 in the X direction. The arms 33 and 34 are provided rotatable about a common rotation axis X7 along the X direction.

[0066] 6, the arm 33 is a bar member provided in a direction along the Z direction. An upper end 331 of the arm 33 in the longitudinal direction is connected to the support 231 of the handle portion 23 so as to be rotatable about a rotation axis X7. A lower end 332 of the arm 33 rotatably supports the pressure roller 30 via the core member 32. The upper end 331 of the arm 33 is located higher in the Z direction than the lower end 332.

[0067] 5, the arm 34 is also a bar member provided in a direction along the Z direction. An upper end 341 of the arm 34 in the longitudinal direction is connected to the support 232 of the handle portion 23 so as to be rotatable about a rotation axis X7. A lower end 342 of the arm 34 rotatably supports the pressure roller 30 via the core member 32. The upper end 341 of the arm 34 is located higher in the Z direction than the lower end 342.

[0068] As a result, even if there are localized irregularities on the installation surface G, the arms 33 and 34 can rotate about the rotation axis X7, allowing the pressing roller 30 to move up and down along the irregularities.

[0069] As shown in FIG. 4, the diameter Da of the pressure roller 30 is set to be larger than the diameter Db of the fixed wheel 222 (Da>Db). 5, when the pressure roller 30 is in contact with the laying surface G, the rotation axis X6 is located on a vertical line VL that passes through the rotation axis X2 of the fixed wheel 222. In this state, the arms 33 and 34 are provided across the pressure roller 30 and the handle portion 23. Therefore, as shown in FIG. 2, the rotation axis X6 of the pressure roller 30 (see FIG. 4) is arranged coaxially with the rotation axis X2 of the fixed wheel 222 when viewed from the Z direction.

[0070] 6, the arm 33 has an extension 333 that branches off between the upper end 331 and the lower end 332 and extends rearward beyond the pressure roller 30. As shown in FIG. 5, the arm 34 also has an extension 343 that branches off between the upper end 341 and the lower end 342 and extends rearward beyond the pressure roller 30.

[0071] As shown in FIGS. 2 and 4, the rear ends of these extending portions 333 and 343 are connected by a rod-shaped gripping portion 35 extending in the X direction. Thereby, the user can displace the pressing roller 30 in the Z direction (the direction of the arrow in FIG. 3) by rotating the roller holder 31 around the rotation axis X7 while gripping the gripping portion 35.

[0072] As shown in FIG. 4, in the X direction, the width W31 from the arm portion 33 to the arm portion 34 of the roller holder 31 is narrower than the distance W23 between the opposing surfaces 231b and 232b of the columns 231 and 232 of the handle portion 23 (W31 < W23). Therefore, when the roller holder 31 is displaced upward in the Z direction, the pressing roller 30 and the arm portions 33 and 34 can be arranged in the space R between the columns 231 and 232 of the handle portion 23 (see the phantom line in FIG. 3). Thereby, the laying portion 3 can be switched between a position where the pressing roller 30 is in contact with the laying surface G and a position separated from the laying surface G.

[0073] The laying device 1 according to the present embodiment has a lock mechanism 9 (stopper) for fixing the position of the roller holder 31 at a position where the pressing roller 30 is arranged in the space R between the columns 231 and 232 of the handle portion 23.

[0074] (Lock mechanism 9) FIG. 9 is a diagram for explaining the lock mechanism 9. (a) of FIG. 9 is an enlarged view of the C region in FIG. 4 and shows a state where the lock mechanism 9 is in the closed position. (b) of FIG. 9 is a diagram showing a state where the lock mechanism 9 is in the open position. FIG. 10 is a diagram for explaining the lock mechanism 9. FIG. 10 is a schematic cross-sectional view taken along the line A - A of (a) in FIG. 9.

[0075] As shown in Figure 9(a), the locking mechanism 9 is provided on the support 232 of the handle portion 23, and is provided so as to be exposed from the support 232 to the space R. As shown in Figure 4, the locking mechanism 9 is provided at a position spaced a height h9 from the installation surface G. This height h9 is the position where the locking mechanism 9 overlaps with the arm portion 34 when viewed from the Y direction when the roller holder 31 is rotated about the rotation axis X7 and displaced upward in the Z direction (see the imaginary line in Figure 5).

[0076] As shown in FIG. 10, the locking mechanism 9 has a positioning portion 91 provided on a front surface 232c of the support column 232 in the Y direction, and a locking portion 95 provided on a rear surface 232d.

[0077] The positioning portion 91 has a fixed plate 92 fixed to the front surface 232c of the support pillar 232 with a bolt B, and a buffer portion 93 provided on the fixed plate 92 at a position that avoids the support pillar 232. The buffer part 93 has a shaft part 931 that penetrates the fixed plate 92 in the Y direction. A plate-shaped head part 932 is provided at the rear end part in the Y direction of the shaft part 931. A spring 933 is fitted onto the shaft part 931. The spring 933 is provided between the fixed plate 92 and the head part 932 in the Y direction so as to be elastically deformable.

[0078] The locking portion 95 has a cylindrical pin 96 fixed to the rear surface 232d of the support pillar 232 with a bolt B, and a movable plate 97 fitted onto the cylindrical pin 96. The movable plate 97 is provided so as to be swingable around an axis Y1 along the Y direction, with the cylindrical pin 96 as a fulcrum.

[0079] 9(a), the movable plate 97 has an operation piece 971 and a locking piece 972 that are perpendicular to each other. The operation piece 971 and the locking piece 952 extend in directions that separate them from each other in the radial direction of the axis Y1.

[0080] A handle 98 is attached to the tip of the operation piece 971. The operation piece 971 side of the movable plate 97 is heavier than the locking piece 972 side by the amount of the handle 98 attached. Therefore, when the locking part 95 is attached to the support 232, the operation piece 971 side is positioned lower in the Z direction than the locking piece 972 side due to its own weight.

[0081] In this state, the movable plate 97 of the locking portion 95 is provided so that the operation piece 971 side is oriented along the Z direction and the locking piece 972 side is oriented along the X direction. The locking piece 972 protrudes from the opposing surface 232b of the support 232 toward the space R (closed position).

[0082] 9(b), when a user grasps the handle 98 and lifts it in a direction (arrow a in the figure) away from the space R, the movable plate 97 swings around the axis Y1. As a result, the operation piece 971 side is oriented along the X direction, and the locking piece 972 side is oriented along the Z direction. Therefore, the locking piece 972 no longer protrudes from the opposing surface 232b of the support 232 toward the space R (open position).

[0083] In this way, when the user swings the movable plate 97 around the axis Y1, the lock mechanism 9 is switched between the open position and the closed position. The user can place the roller holder 31 in the space R by the following procedure. (i) The handle 98 is lifted to set the movable plate 97 to the open position (see FIG. 9(b)). (ii) The gripping portion 35 (see FIG. 4) of the roller holder 31 is lifted up, and the arm portion 34 is brought into contact with the buffer portion 93 of the positioning portion 91. (iii) Release the handle 98 to move the movable plate 97 to the closed position (see FIG. 9(a)).

[0084] 10, the arm 34 of the roller holder 31 is arranged between the buffer portion 93 of the positioning portion 91 of the locking mechanism 9 in the Y direction and the locking piece 972 of the movable plate 97. The arm 34 is locked in a state where it is pressed against the locking piece 972 by the biasing force of the spring 933 of the buffer portion 93. This restricts the rotation of the arm 34 around the rotation axis X7 (see FIG. 5).

[0085] Therefore, since the pressure roller 30 can be held within the space R, for example, when no laying work is being performed, the cart 2 can be transported while the pressure roller 30 is kept away from the laying surface G. This reduces the adhesion of dirt, scratches, etc. to the pressure roller 30.

[0086] Fig. 11 is a schematic diagram illustrating the pulling out of the magnetic tape 10. For ease of explanation, the distances in the Y direction between the tape holder 4, the transport unit 5, the tension roller TR, and the pressure roller 30 are shown wide in Fig. 11. The transport unit 5 is also shown enlarged.

[0087] 11, a roll of magnetic tape 10 wound around a core material S1 is attached to a tape holder 4. The magnetic tape 10 attached to the tape holder 4 is pulled out from below the rotation axis X3. The magnetic tape 10 pulled out from the tape holder 4 is routed so as to come into contact with the area above the rotation axis X4 of the first roller 6 and the area below the rotation axis Xt of the tension roller TR, and then inserted between the pressure roller 30 and the laying surface G.

[0088] When the carriage 2 is moved forward in the Y direction with the magnetic tape 10 inserted between the pressure roller 30 and the laying surface G, the pressure roller 30 rolls on the magnetic tape 10 around the rotation axis X6 (white arrow in the figure). As a result, tension T acts on the magnetic tape 10 in the pull-out direction (black arrow in the figure).

[0089] The tension T acts on the rolled magnetic tape 10 attached to the tape holder 4. As a result, the magnetic tape 10 attached to the tape holder 4 is pulled out in order as the carriage 2 moves. The tape holder 4, first roller 6, tension roller TR, and pressure roller 30 are arranged in this order from upstream to downstream in the direction in which the magnetic tape 10 is pulled out.

[0090] 11, when the magnetic tape 10 is pulled out from the tape holder 4, the main body 11 is positioned on the upper side in the Z direction and the release paper 13 is positioned on the lower side in the Z direction. Therefore, the release paper 13 of the magnetic tape 10 comes into contact with the first roller 6.

[0091] 8, the first roller 6 is configured to accommodate the magnetic tape 10 in a recess 65 provided in a bush 64. This makes it difficult for the magnetic tape 10 to fall off the first roller 6 while being pulled out.

[0092] As shown in the enlarged area of Figure 11, when the magnetic tape 10 passes the first roller 6 and moves toward the tension roller TR, the release paper 13 separates from the main body 11. The release paper 13 separated from the main body 11 is taken up by the second roller 7.

[0093] 8, a core material S2 is fitted onto the bushing 74 of the second roller 7. The release paper 13 is adapted to be wound around the core material S2.

[0094] 11, when magnetic tape 10 moves downstream in the pull-out direction on first roller 6, frictional force is generated between magnetic tape 10 and first roller 6. As a result, first roller 6 rotates around rotation axis X4 along the pull-out direction (white arrow in the figure). As a result, the belt V wound around the pulley 63 of the first roller 6 goes around the rotation axis X4 and the rotation axis X5 (hatched arrows in the drawing).

[0095] In conjunction with the rotation of the belt V, the pulley 73 of the second roller 7 rotates around the rotation axis X5. The rotation direction of the pulley 73 is the same as the rotation direction of the pulley 63. The bushing 74 and core material S2, which rotate integrally with the pulley 73, also rotate around the rotation axis X5 (indicated by the white arrow in the figure). As a result, the second roller 7 rotates using the rotation of the first roller 6 as a drive source, and automatically winds the release paper 13 onto the core material S2.

[0096] 6, the wrap radius r of the belt V is the same for the pulley 63 of the first roller 6 and the pulley 73 of the second roller 7. Therefore, the rotation speed of the pulley 73 of the second roller 7 is the same as that of the pulley 63 of the first roller 6. Therefore, the movement amount of the magnetic tape 10 moving downstream in the pull-out direction on the first roller 6 and the amount of release paper 13 taken up by the second roller 7 are made to match. This allows the first roller 6 to transport the main body 11 downstream and the second roller 7 to take up the release paper 13 in parallel.

[0097] When the release paper 13 is taken up by the second roller 7, the adhesive layer 12 of the magnetic tape 10 is exposed. As shown in the enlarged area of Figure 11, as the magnetic tape 10 passes through the tension roller TR, the adhesive layer 12 is oriented in the Z direction facing the laying surface G before it reaches the pressure roller 30. In this state, the pressure roller 30 presses the main body 11 against the laying surface G, so that the adhesive layer 12 is accurately adhered to the laying surface G.

[0098] (Replacing the roll) When the magnetic tape 10 attached to the tape holder 4 is fully pulled out, only the core material S1 remains fitted around the bushing 44. The core material S2 fitted around the bushing 74 of the second roller 7 has the release paper 13 wound around it for the entire length of the magnetic tape 10.

[0099] In this embodiment, the cores S1 and S2 are detachably fitted around bushings 44 and 74, respectively. This makes it easy to collect used cores S1 and S2 and to replenish with new magnetic tape 10, facilitating setup changes. Furthermore, by reusing the used core S1 on the tape holder 4 side and fitting it around the bushing 74 of the second roller 7, it is possible to reduce the need to prepare a new core S2 for winding up the release paper 13.

[0100] (Brake mechanism 8) Here, when the magnetic tape 10 is pulled out, it is preferable that the carriage 2 moves at a constant speed so that a constant tension T is applied to the magnetic tape 10. However, it is difficult to always move the carriage 2 at a constant speed, and the carriage may stop or slow down during the pull-out process.

[0101] If the carriage 2 is stopped or decelerated during the pull-out process, the inertial force may cause the tape holder 4 to rotate significantly relative to the amount of movement of the carriage 2. If this happens, an excess of the magnetic tape 10 is pulled out from the tape holder 4, and the tension T no longer acts. This causes the magnetic tape 10 to become loose between the tape holder 4 and the pressure roller 30 (see the imaginary line in FIG. 11). If the movement of the carriage 2 is resumed or accelerated while the magnetic tape 10 is loose, this may affect the adhesion between the adhesive layer 12 and the installation surface G.

[0102] Therefore, the cable laying device 1 according to this embodiment is provided with a brake mechanism 8 for controlling the amount of rotation of the tape holder 4.

[0103] 12 is a diagram illustrating the brake mechanism 8. FIG. 12 is a schematic cross-sectional view taken along line AA in FIG. 12, the brake mechanism 8 is provided on the outer diameter side of the disc plate 43 of the tape holder 4. The disc plate 43 has an inner peripheral portion 431 that abuts against the rolled magnetic tape 10 in the direction of the rotation axis X3, and an outer peripheral portion 432 that surrounds the outer peripheral edge 431a of the inner peripheral portion 431 all around and is formed to be thinner than the inner peripheral portion 431.

[0104] The diameter D431 of the inner circumferential portion 431 is set to be larger than the maximum diameter D10_max of the magnetic tape 10 wound in a roll (D431>D10_max). The brake mechanism 8 is provided at a position overlapping with the outer circumferential portion 432 of the disc plate 43 when viewed from the direction of the rotation axis X3.

[0105] The brake mechanism 8 has a pair of brake pads 82, 82 that face each other with a gap in the direction of the rotation axis X3, and a case 81 that houses the pair of brake pads 82, 82. The pair of brake pads 82, 82 are provided with a gap between them on one side and the other side of the outer circumferential portion 432 of the disc plate 43 in the direction of the rotation axis X3.

[0106] The pair of brake pads 82, 82 are connected to a brake lever 85 (see FIG. 1) via a wire 83. One end of the wire 83 in the longitudinal direction is connected to the pair of brake pads 82, 82, and the other end is connected to the brake lever 85. The pair of brake pads 82, 82 are displaced in a direction toward each other when the wire 83 is pulled in conjunction with the operation of the brake lever 85. The amount of displacement of the pair of brake pads 82, 82 changes according to the amount of pulling of the wire 83 (the amount of operation of the brake lever 85).

[0107] When the user operates the brake lever 85 (holds it together with the grip 237) and pulls the wire 83, the pair of brake pads 82, 82 are displaced in directions approaching each other in accordance with the amount of pulling of the wire 83 (see the imaginary lines in FIG. 12 ). As a result, the pair of brake pads 82, 82 clamp the outer circumferential portion 432 of the disc plate 43, and a braking force acts on the disc plate 43.

[0108] For example, when the brake lever 85 is operated by a large amount (gripped tightly), the wire 83 is pulled by a large amount, so that the pair of brake pads 82, 82 are displaced significantly in directions approaching each other, sandwiching the disc plate 43 so that it cannot rotate relative to the brake pads 82. On the other hand, when the brake lever 85 is operated by a small amount (a weak grip), the amount of pull on the wire 83 also decreases. In this case, the pair of brake pads 82, 82 are displaced toward each other, slidably sandwiching the disc plate 43. This reduces the rotation speed of the disc plate 43.

[0109] As shown in Fig. 6, the case 81 is fixed to the upper end portion 251 of the first support wall 25 with a bolt B. Therefore, when the disc plate 43 is sandwiched between the pair of brake pads 82, 82, its rotation relative to the first support wall 25 is restricted. As shown in Fig. 7, the outer shaft 42 and the bushing 44, which are provided so as not to rotate relative to the disc plate 43, are also restricted from rotating relative to the first support wall 25. The core material S1 fitted onto the bushing 44 is also restricted from rotating relative to the first support wall 25.

[0110] In this way, the clamping force of the pair of brake pads 82, 82 on the disc plate 43 can be adjusted according to the amount of operation of the brake lever 85, so it is possible to appropriately switch between stopping and slowing down the rotation of the disc plate 43. Therefore, the amount of rotation of the disc plate 43 can be controlled in accordance with changes in the speed of the bogie 2.

[0111] As a result, in the brake mechanism 8, when the user operates the brake lever 85, a braking force is applied to the disc plate 43, reducing excessive rotation of the tape holder 4. This reduces the occurrence of slack in the rolled magnetic tape 10.

[0112] Therefore, even if the carriage 2 is stopped or decelerated, the brake mechanism 8 maintains a constant tension T acting on the magnetic tape 10. Therefore, even if the carriage 2 is stopped and then starts moving again, or is decelerated and then accelerated, the adhesion between the adhesive layer 12 and the installation surface G is less likely to be affected.

[0113] Figure 13 is a schematic diagram illustrating the rotation of the laying device 1. Figure 13 is a view of the laying device 1 as seen from above in the Z direction. Note that in Figure 13, the carriage 2, swivel wheel 221, fixed wheels 222L and 222R, and pressure roller 30 are shown schematically to make it easier to understand their positional relationships.

[0114] As shown in Figure 13, the laying device 1 lays the magnetic tape 10 by moving the carriage 2 along a pre-drawn marking line Lp while pressing the magnetic tape 10 against the laying surface G with the pressure roller 30. The carriage 2 is positioned in a direction along the marking line Lp. When a user manually pushes the handle portion 23 (see Figure 1) from the rear side of the carriage 2 toward the front side, the carriage 2 moves along the marking line Lp.

[0115] Here, the marking line Lp may be formed by combining a straight portion Ls and a curved portion Lc. When the carriage 2 moves straight along the straight portion Ls, the rotation axis X1 of the swivel wheel 221 is parallel to the rotation axis X2 of the fixed wheels 222L and 222R.

[0116] When the carriage 2 turns along the curved section Lc, the swivel wheel 221 turns around the straight line Lz and tilts in a direction along the curved section Lc. Therefore, the rotation axis X1 of the swivel wheel 221 intersects with the rotation axes X2 of the fixed wheels 222L and 222R. In this case, the turning center Cp of the carriage 2 is the intersection of the rotation axis X1 of the swivel wheel 221 and the rotation axis X2 of the fixed wheels 222L and 222R.

[0117] In this embodiment, when viewed from the Z direction, the rotation axis X6 (see FIG. 5) of the pressure roller 30 is provided at a position coaxial with the rotation axis X2 of the fixed wheels 222L, 222R. Therefore, the rotation center of the pressure roller 30 coincides with the rotation center Cp of the carriage 2.

[0118] Figure 14 is a diagram illustrating the rotation of the installation device 100 according to a comparative example. Figure 14 is a diagram of the installation device 100 viewed from above in the Z direction. Note that in Figure 14, the carriage 2, swivel wheel 221, fixed wheels 222L and 222R, and pressure roller 30 are shown schematically to make it easier to understand their positional relationships.

[0119] 14, in the laying device 100 according to the comparative example, when viewed from the Z direction, the pressure roller 30 is provided at a position offset rearward from the rotation axis X2 of the fixed wheels 222L, 222R. In this case, the pivot center Cp' of the pressure roller 30 is shifted from the pivot center Cp of the carriage 2.

[0120] Therefore, when the carriage 2 is rotated around the rotation center Cp, the pressure roller 30 having the different rotation center Cp' rotates while slipping radially outward from the rotation center Cp. As a result, a force (side slip force, white arrow in FIG. 14) acts on the carriage 2 in the radially outward direction, hindering smooth rotation.

[0121] 13, in the laying device 1 according to this embodiment, when viewed from the Z direction, the rotation axis X6 (see FIG. 5) of the pressure roller 30 is positioned coaxially with the rotation axis X2 of the fixed wheels 222L, 222R. Therefore, the rotation center of the pressure roller 30 coincides with the rotation center Cp of the carriage 2.

[0122] As a result, even when the carriage 2 is rotated around the rotation center Cp, the pressure rollers 30 are less likely to slip radially outward. Therefore, the carriage 2 can rotate smoothly without receiving a side slip force from the pressure rollers 30.

[0123] In the laying device 1 according to this embodiment, the rotation axis X6 (see FIG. 5) of the pressure roller 30 is coaxial with the rotation axis X2 of the fixed wheels 222L, 222R when viewed from the Z direction, but this is not limiting. By bringing the pressure roller 30 close enough to overlap with the rotation axis X2 of the fixed wheels 222L, 222R when viewed from the Z direction, the side slip force acting on the carriage 2 can be significantly reduced.

[0124] Examples of the installation device 1 according to certain aspects of the present invention are listed below. (1) The laying device 1 lays a magnetic tape 10 (tape) for guiding an automatic guided vehicle. The laying device 1 includes a carriage 2 that can carry a magnetic tape 10 and move in a direction (laying direction) along the marking line Lp of the magnetic tape 10; The magnetic tape 10 is provided with a pressure roller 30 that moves together with the carriage 2 in a direction along the marking line Lp and presses the magnetic tape 10 against the laying surface G. The carriage 2 is provided with a swivel wheel 221 on the front side (one side) in the direction along the marking line Lp, and with fixed wheels 222L and 222R on the rear side (the other side). When viewed from the Z direction, which is a direction perpendicular to the laying surface G, the pressure roller 30 is provided at a position overlapping with the rotation axis X2 of the fixed wheels 222L and 222R.

[0125] For example, when laying the magnetic tape 10 along the curved portion Lc of the score line Lp, if the pressure roller 30 is provided at a position offset from the rotation axis X2 of the fixed wheels 222L, 222R, the rotation center of the pressure roller 30 will be shifted from the rotation center Cp of the carriage 2 (see FIG. 14). In this case, when the carriage 2 is rotated, a force acting radially outward from the pressure roller 30 acts, hindering smooth rotation. Therefore, by configuring as described above, the rotation center of the pressure roller 30 approaches the rotation center Cp of the carriage 2, so that even when the carriage 2 turns, the force acting radially outward from the pressure roller 30 becomes smaller. This improves the turning ability of the carriage 2.

[0126] (2) When viewed from the Z direction, the rotation axis X6 of the pressure roller 30 is coaxial with the rotation axis X2 of the fixed wheels 222L and 222R.

[0127] With this configuration, the rotation center of the pressure roller 30 coincides with the rotation center Cp of the carriage 2, so that even when the carriage 2 turns, the force acting radially outward from the pressure roller 30 becomes smaller. This allows the turning ability of the carriage 2 to be further improved.

[0128] (3) The magnetic tape 10 is wound in a roll and mounted on the carriage 2, with the outer periphery of the tape pulled out toward the pressure roller 30. The magnetic tape 10 has a main body 11 made of a magnetic material, an adhesive layer 12 provided on one surface 11a of the main body 11 (the surface facing the installation surface G), and a release paper 13 covering the adhesive layer 12. On the carriage 2, a first roller 6 and a second roller 7 (a pair of rollers) are provided on the upstream side of the pressure roller 30 in the direction in which the magnetic tape 10 is pulled out, and the first roller 6 and the second roller 7 face each other in the Z direction. The first roller 6 sends the main body 11 to the pressure roller 30 . The second roller 7 winds up the release paper 13 peeled off from the main body 11. The rotation of the first roller 6 and the second roller 7 is synchronized with each other via pulleys 63 and 73 and a belt V wound around the pulleys 63 and 73, which are rotation transmission mechanisms.

[0129] With this configuration, the first roller 6 can transport the main body 11 downstream and the second roller 7 can take up the release paper 13 in parallel.

[0130] (4) The second roller 7 includes an inner shaft 71 (shaft) that is not rotatable relative to the carriage 2, and an outer shaft 72 (hollow shaft) that is fitted onto the inner shaft 71. A pulley 73 of the rotation transmission mechanism is connected to the outer shaft 72 . A bushing 74 is press-fitted onto the outer periphery of the outer shaft 72 . A core material S2 for winding the release paper 13 is fitted onto the bushing 74 so as not to rotate relative to it. The core material S2 is provided detachably in the direction of the rotation axis X5 of the outer shaft 72.

[0131] With this configuration, the core material S2 with all of the release paper 13 wound up can be easily collected, making setup changeover easier.

[0132] (5) The carriage 2 is provided with a tension roller TR between the first roller 6 and the pressure roller 30 in the direction in which the magnetic tape 10 is pulled out.

[0133] With this configuration, before the magnetic tape 10 is pressed onto the laying surface G by the pressure roller 30, the adhesive layer 12 is oriented in the Z direction to face the laying surface G. This allows the adhesive layer 12 to be accurately adhered to the laying surface G.

[0134] (6) The pressure roller 30 is connected to the carriage 2 via the arms 33 and 34 . The arms 33 and 34 are connected to the carriage 2 so as to be rotatable around a rotation axis X7. In addition, the upper ends 331 and 341 of the arms 33 and 34, which are connected to the carriage 2, are arranged higher in the Z direction than the lower ends 332 and 342, which are connected to the pressure roller 30. The carriage 2 has a locking mechanism 9 (stopper) that fixes the position of the pressure roller 30 at a position where the pressure roller 30 is separated from the laying surface G.

[0135] With this configuration, for example, when no laying work is being performed, the dolly 2 can be transported while the pressure roller 30 is kept away from the laying surface G. This reduces the adhesion of dirt, scratches, etc. to the pressure roller 30.

[0136] In this embodiment, the rotation of the first roller 6 and the rotation of the second roller 7 are synchronized by wrapping the belt V around the pulley 63 of the first roller 6 and the pulley 73 of the second roller 7, as an example. However, the present invention is not limited to this. For example, instead of the pulley and belt mechanism, a gear mechanism consisting of multiple gears may be provided so that the rotation of the first roller 6 and the rotation of the second roller 7 are synchronized. In this case, the gear mechanism constitutes the rotation transmission mechanism.

[0137] Furthermore, in the present embodiment, the brake mechanism 8 is exemplified in which the pair of brake pads 82, 82 are operated by the wire 83. However, the present invention is not limited to this. For example, the pair of brake pads 82, 82 may be operated by hydraulic pressure.

[0138] Furthermore, in this embodiment, the brake mechanism 8 has been illustrated as having a structure in which the disc plate 43 is sandwiched between a pair of brake pads 82, 82, but the invention is not limited to this. For example, the brake mechanism may be configured such that a torsion spring is interposed between the inner shaft 41 and outer shaft 42 of the tape holder 4, and a biasing force acts on the outer shaft 42 in the direction opposite to the direction in which the magnetic tape 10 is pulled out. This also makes it possible to constantly apply tension T to the magnetic tape 10. This reduces the occurrence of slack in the magnetic tape 10.

[0139] In the present embodiment, the cart 2 is exemplified as being pushed by the user while gripping the handle portion 23. However, the present invention is not limited to this. For example, the cart may be self-propelled by the driving force of a motor.

[0140] Although the embodiment of the present invention has been described above, the above embodiment merely shows one application example of the present invention, and the technical scope of the present invention is not intended to be limited to the specific configuration of the above embodiment. Appropriate modifications are possible within the scope of the technical concept of the invention. [Explanation of symbols]
