Description

  The present invention relates to a cable connecting apparatus, and more particularly to an apparatus having a structure in which cables are sequentially passed through a plurality of rotating separating plates.

  In general, when two members are connected to each other by a cable in an electric device and one member moves relative to the other member, sliding between the brush or the contact and the conductive material is caused. There are known rotary connectors that use mercury instead of slip rings and brushes.

However, the slip ring and the rotary connector have an advantage that they can be rotated as much as possible. On the other hand, the slip ring tends to generate noise from the brush portion, so that it tends to be avoided when the noise is disliked. Further, since the rotary connector using mercury uses mercury, there is no problem of noise, but there are many cases where hesitates to use it due to recent environmental problems. Therefore, in applications where the number of rotations may be limited, a method using a cable winding drum using a separating plate has attracted attention. As a method for this, a technique for absorbing the torsion by bending the cable separation plates by using a plurality of separator plates in order to prevent the cable fixing portion will twist is known (for example, the following Patent Documents 1 and 2).

Furthermore, the movable side cable is wound around the drum in a spiral shape, the fixed side cable is drawn into the inner peripheral side of the drum, and the fixed side cable is wound around the inner peripheral side of the drum in a spiral shape. A cable take-up device adapted to be drawn out is known (for example, refer to Patent Document 3 below).

  However, in the device structure using the separation plate, when the space between the separation plates is narrowed to conserve space, as shown in FIG. There is a phenomenon in which the cable is caught between the cables, and there is a possibility that a cable jumping phenomenon may occur in a place where the cables are in contact with each other, such as a portion J. Therefore, there is a problem that smooth rotation cannot be obtained. Further, when the separation plate is attached in the vertical direction, the cable protrudes from the outer periphery of the separation plate, and there is also a problem that the smooth rotation operation is hindered. On the other hand, if the distance between the separation plates is widened, the problem of interference between the cables is eliminated, but the apparatus becomes larger as the distance increases, and the apparatus becomes larger as the number of rotations is increased. .

  An object of the present invention is to provide a structure that smoothly rotates even when the interval between the separation plates is reduced, in a cable connection device using a plurality of separation plates. That is, a more specific problem of the present invention is to prevent the cables from interfering with each other in a cable connecting device using a plurality of separation plates that are sequentially rotated with the rotation of a rotating body that rotates together with a part of the cable. This is to stabilize the rotation of the drum.

In order to achieve the above object, a cable connecting device according to the present invention is arranged coaxially with each other, in which a cable, a rotating body that rotates together with a part of the cable, and the other part of the cable are sequentially drawn. A plurality of separating plates, wherein the plurality of separating plates rotate sequentially along with the rotation of the winding drum, and penetrate the plurality of separating plates along an axis. The cable has a common axis, and the cable has a first passage portion passing through a portion near the outer periphery of the first separation plate among the plurality of separation plates, and a second separation adjacent to the first separation plate. A second passage portion passing through a portion near the inner periphery of the plate, and alternately passing through the first separation plate and the second separation plate in the axial direction, and the first passage portion and the first passage portion. The cable part between the two passage parts is in front of the first separating plate. Extends through about said axis in a predetermined rotational direction at the second separation plates, mounted on said separator plate while being arranged in said second separation plates between the first of said separator plate the interposed between different sites cables interference prevention member which both are prevented from interfering provided, the interference prevention member, around the said axis, the relative said second passage portion When the second separation plate is rotated in the rotation direction with respect to the first separation plate, the cable portion is arranged with the second passage site. does not pass through between the interference preventing member, the shaft, and wherein both Rukoto wound around said second passage portion and the interference prevention member. Here, it is preferable that the interference preventing member is composed of a pin or a roller protruding from the separation plate. Further, as the rotating member rotates with a portion of the cable, as long as the plurality of separation plates by the rotation acts to rotate successively may be any one, for example, winding the cable Examples include a winding drum, a rotating stage, a turntable, and a vehicle rotating handle to which the end of a cable is connected.

Here, the interference prevention member, the second passage portion of said cable with respect to the second separator plate, et provided interposed allows a position is between the other portion of the cable. For example, cable portion to the second passage portion of the cable with respect to the inner peripheral portion near the second separator plate adjacent the first passage section position or these cables with respect to the outer peripheral portion close of the first separation plate, said first In the case of being arranged counterclockwise between the first separator plate and the second separator plate, when the second separator plate rotates a predetermined amount counterclockwise with respect to the first separator plate, cable portion does not pass between the second passage portion and the interference prevention member, interference prevention member as both wound around both of the second passage portion and the interference prevention member is disposed.

Next, another cable connecting device according to the present invention includes a cable, a rotating body that rotates together with a part of the cable, and a plurality of coaxially arranged parts in which the other part of the cable is sequentially drawn. A cable connecting device configured to sequentially rotate with the rotation of the rotating body, and a common shaft penetrating the plurality of separation plates along an axis. The cable includes a first passage portion that passes through a portion near the outer periphery of the first separation plate among the plurality of separation plates, and an inner periphery of the second separation plate adjacent to the first separation plate. A second passage portion that passes through the offset portion, and alternately passes through the first separation plate and the second separation plate in the axial direction, and the first passage portion and the second passage portion. Between the first separator plate and the second separator plate. Extending around the axis in a predetermined rotational direction, disposed between the first separation plate and the second separation plate and mounted on the second separation plate, An interference preventing member that is interposed between different parts of the cable and prevents the two from interfering with each other is provided, and the interference preventing member passes the second passing part into the second separating plate to pass through the second separating part. And when the second separation plate rotates in the rotation direction with respect to the first separation plate, the cable portion is connected to the second passage site and the interference prevention member. It is characterized by being wound together around the shaft and the interference preventing member without passing between them . The holding member can be constituted by, for example, a cylindrical member or a disk-like member that sandwiches the cable from both the front and back sides of the separation plate and fixes the cable to the separation plate. The holding member may be attached to the separation plate so as to be movable in a radial direction. As a result, the position of the passing portion of the cable can be moved in the radial direction of the separation plate, so that the rotation amount of the separation plate can be increased. Furthermore, it has another holding member which hold | maintains the said 1st passage part in the said outer peripheral part of the said 1st separating plate, This other holding member is radial direction with respect to the said 1st separating plate. May be movably attached.

Furthermore, in the present invention, it is preferable that a rising portion for preventing the cable from protruding from the outer periphery is provided on the outer periphery of the first separation plate and the second separation plate . Here, it is desirable that the rising amount of the rising portion in the axial direction is substantially the same as the interval between two adjacent separation plates.

In the present invention, the first separation plate and the second separation plate have a cable fixing portion that fixes the first passage portion and the second passage portion , and the cable fixing portion includes the cable fixing portion. It is preferable that a guide structure for guiding the first and second passage portions from the rear surface side to the front surface side of the separation plate is provided. Thereby, since the load added to the passage part of a cable can be reduced, even if the space | interval of a separating plate is made small, it can prevent that damage, such as a bending and a disconnection, arises in the said passage part.

  Furthermore, in the present invention, a plurality of the cables are wound sequentially between the plurality of separation plates in parallel with the inside and outside in the radial direction, and a portion between the separation plates of the cable wound on the outer peripheral side is provided. It is preferable that the cable is configured to be longer than a portion between the separation plates of the cable wound on the inner peripheral side. According to this, since the outer diameter of the plurality of cables can be reduced compared to the case where a single thick cable is sequentially passed between the plurality of separation plates, the plurality of cables are wound in parallel in the radial direction. The distance between the separation plates can be reduced by making the outer peripheral cable longer than the inner peripheral cable.

In the present invention, by providing the interference preventing member, since the sites different cable between the first separating plate and a second separator plate abuts directly is prevented, caught between the cable is reduced Smooth rotation is possible. In addition, since smooth rotation can be performed in this manner, the distance between the separation plates can be reduced and the amount of rotation can be increased as compared with the conventional case, so that the apparatus can be easily downsized.

In particular, the interference preventing member is interposed between the second passage portion of the cable with respect to the second separation plate and another portion, thereby reducing the interval between the separation plates and increasing the rotation amount. The problem that is likely to occur due to the cable, that is, the other part is prevented from biting into the passage part of the cable.

  Embodiments of a cable connecting device according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing the entire structure of a cable reel (cable winding device) using a separating plate, and a motor 4 or a spring spring, a handle or the like is attached to a base 2 which is a fixed object.

  A winding drum 6 is integrally attached to the shaft 5 of the motor, and the winding drum 6 rotates in a desired direction by the rotation of the motor 4. A cable 8 is wound around the outer periphery of the drum 6, and one end 8 a of the cable 8 is separated from the drum 6 and goes out of the base 2 to reach a target member or rewind. The other end 8b of the cable 8 is drawn from the drum 6 to the inside, and passes through a separation plate 14 fixed to the drum 6 and a plurality of separation plates 16, 18, 20, 22 provided rotatably. After passing through the separation plate 24 fixed to the base 2, it goes out from the cable outlet 3 of the base 2 and reaches the target member.

  For example, in the case of a gymnasium, if the cable 12 is connected to a power source, the main body is installed on the ceiling in the center of the gymnasium, and an auxiliary illuminator is connected to the cable 8a, the floor can be used when necessary without the cable crawling. Available in height.

  In this embodiment, the cable 8 used for the drum 6 and the cable 10 and the base 2 used from the base 2 through the separation plate 14 to 24 to reach the cable outlet 3 are externally connected. The cable 12 that appears in the above is indicated by a different number, but this is only described with a different number because the role of the cable is different at each location. Of course, the same cable is used. However, it is possible to use separate cables by providing a terminal block.

  Further, any number of separation plates 16, 18, 20, and 22 can be provided between the separation plate 14 fixed to the drum 6 and the separation plate 24 fixed to the base 2 so as to be rotatable. The required number can be provided depending on the length, thickness, hardness, etc. In this embodiment, 12 drums are provided so that the drum can cope with 12 rotations. In addition, the separation plate has a structure in which the separation plates 18 and 22 having a structure provided with interference prevention members (pins or rollers) 26 and 28 for preventing cable interference and the separation plates 16 and 20 without the interference prevention member are alternately overlapped. The collar 13 is inserted in the portion of the shaft 5 so as to be arranged at a certain interval. Further, it is made rotatable with respect to the shaft 5 using a bearing (not shown) or the like. In the separation plates 18 and 22 having the structure provided with the interference prevention members 26 and 28, the cable 10 passes in a portion near the center, and in the separation plates 16 and 18 without the interference prevention member, the cable 10 is located in a portion far from the center. Is passing.

  In this structure, when the motor 4 rotates, the drum 6 rotates, and the cable 8 is fed out accordingly. Although the drum 6 and the separation plate 14 rotate synchronously, there is a certain margin in the number of separation plates 16, 18, 20, 22 and the like provided between the drum 6 and the cable 10 and the length of the cable 10. The rotation is not transmitted to the cable 12. Further, since the twist of the cable due to the rotation of the drum 6 is absorbed by the separating plate portion, the cable 8 is drawn out without rotating.

  Next, the relationship between the separating plates 16, 18, 20, 22 and the cable 10 will be described with reference to FIG. The cable 10 coming out of the separation plate 16 from a position 16a far from the shaft 5 is fixed to the separation plate 18 at a position 18b which is curved in the left rotation direction around the shaft 5 and close to the shaft. Similarly, the cable coming out from the position 18b close to the axis of the separation plate 18 is bent in the left rotation direction and is fixed at a position 20a far from the shaft 5 of the separation plate 20. The cable 10 coming out of the separation plate 20 from the position 20a far from the shaft 5 is fixed to the separation plate 22 at a position 22b that is bent in the left rotation direction around the shaft 5 and close to the shaft. As described above, in each of the separation plates, the cable fixing position is alternately repeated at a position close to the shaft 5 and a position far from the shaft 5, and the cable 10 is attached to the separation plates 18 and 22 where the cable is fixed at a position close to the shaft. In the vicinity of the fixed positions 18b and 22b, interference prevention members 26 and 28 for preventing cable interference are provided slightly outside the fixed positions 18b and 22b in the left rotation direction around the shaft 5.

  FIG. 3 is an explanatory view showing the state of the cable 10 between the separation plates 20 and 22, and the states (c) and (d) in which the cable is loosely wound are states in which the separation plates are not rotated with respect to each other. ) (B) shows a state in which the cable 10 is wound after the separating plates 20 and 22 are rotated almost once. In FIG. 3C, the separation plate 20 is provided with a notch 21 in a part of the outer peripheral portion, and the cable 10 protrudes from the back side of the separation plate 20 to the front side (20a). The cable 10 that has come out is bent in the left direction as it is, and after making a half turn along the rising portion 30 provided on the outer periphery of the separation plate 20, enters the center direction, and almost half turns and is close to the center inside the notch 21. The cable 10 is fixed to the guide portion 32 of the separation plate 22 provided in the portion, and the cable 10 comes out from the back side of the separation plate 22 to the front side of the separation plate 22 (22b).

  The rising portion 30 is provided on all the separation plates, and prevents the cable 10 from jumping out from the outer periphery of the separation plate. Further, the separation plate is provided with a guide portion 32 so that the cable 10 can be guided in a guide shape that is not bent or disconnected and has a minimum shape and protects the surface of the cable. It is fixed to the front and back of the separator plate with few bulges with strings. That is, the guide portion 32 is provided in a cable fixing portion where a passage portion of the cable 10 is fixed to the separation plate. Note that this fixing method is also used in the cutout portion 21 as well. The guide portion 32 abuts and supports the passage portion of the cable 10 with respect to the separation plate, and passes the passage portion from the back surface side to the front surface side of the separation plate along a predetermined route (a route inclined with respect to the surface of the separation plate). A guide surface is provided to guide the user. The distance between the separation plates 20 and 22 is set to such a dimension that one cable can move with a margin. The interference prevention member 26 that protrudes in the direction of the separation plate 20 provided on the back surface of the separation plate 22 and the surface thereof are provided. The height of the provided interference prevention member 28 is also slightly smaller than the interval between the separation plates. In this way, the distance between the separation plates is set to the minimum distance at which the cable diameter can be moved with a margin, thereby minimizing the thickness due to the overlap of the separation plates.

  3C, for example, when only the separation plate 22 is rotated in the direction of the arrow h while the separation plate 20 is fixed, the position 22b of the passage portion of the cable 10 with respect to the separation plate 22 and the interference prevention member 26 are rotated in the direction of the arrow. Then, after about one rotation, the state shown in FIG. In this state, the cable 10 is wound around the interference preventing member 26. However, as shown in FIG. 3B, the cable 10 does not enter the inside, so that the cables do not interfere with each other, and the cable 10 rotates in the reverse direction. Smooth movement is sometimes obtained.

  FIG. 3 depicts a state where a twist of about one rotation is absorbed between two separation plates. If the cable is tightened between the two separation plates or if the cable is loose enough, the hardness of the cable will follow and the rotational force will be transmitted to the next separation plate, which will be rotated sequentially, but a stopper will be provided between the separation plates. (Omitted) The rotation is transmitted more reliably and the durability of the cable is improved. That is, a stopper structure that abuts between adjacent separation plates is provided so that adjacent separation plates rotate relatively by a predetermined amount of rotation but do not rotate further. In this way, the degree of deformation of the cable portion between the passing portions with respect to the adjacent separation plates always corresponds to the angle equal to or less than the predetermined rotation amount, so that the load applied to each portion of the cable can be made uniform.

  FIG. 3E shows the structure of an interference preventing member 26 ′ that is rotatably attached to the separation plate. The interference preventing member 26 'includes a support shaft 26a' attached to the separation plate, and a roller (or roller) 26b 'mounted rotatably on the support shaft 26a'. The roller 26b 'is not only interposed between different parts of the cable 10 in the same manner as the interference preventing member 26, but also exhibits an interference preventing function, and also functions to smoothly guide the cable 10 in its extending direction (winding direction). It also has. Such a structure can be used for any of the interference preventing members 26 and 28 described above.

  FIG. 4 shows a state in which the twist of about two turns is absorbed when the cable is thin with the same structure as FIG. 3, and FIG. 4C shows a state where the cable is loosely wound. When the separation plate 22 is rotated in the direction of the arrow h while the separation plate 20 is fixed, the position 22b of the passing portion of the cable 10 with respect to the separation plate 22 and the interference prevention member 26 are rotated in the direction of the arrow and about two rotations are performed. It becomes the state of.

  5 and 6 show a second embodiment. A hole is formed in a part of the outer peripheral portion of the separation plate 20 (not shown), and the cable 10 protrudes from the back side of the separation plate 20 to the front side (20c). The cable 10 that has come out is bent in the left direction as it is, and after having made a half turn along the rising portion 30 provided on the outer periphery of the separation plate 20, the cable 10 enters the center direction, and is a hole provided in a portion that is almost half a turn and close to the center. (Not shown), the separation plate 22 protrudes from the back side to the front side (22d). By attaching the cylindrical (or disk-shaped) interference prevention members 26a and 28a shown in FIG. 5C from both sides of the hole so as to sandwich the cable 10 in the separation plates 20 and 22, and fixing with screws or the like, The cable 10, the separation plates 20 and 22, and the interference preventing members 26a and 28a are fixed in close contact. These interference prevention members 26 a and 28 a constitute the holding member that holds the passage portion of the cable 10 with respect to the separation plate 22 on the separation plate 22. In this embodiment, the structure other than the interference preventing members 26a and 28a is substantially the same as that shown in FIG.

  6C, for example, when only the separation plate 22 is rotated in the direction of the arrow h while the separation plate 20 is fixed, the interference preventing members 26a and 28a provided at the position 22d of the passage portion of the cable 10 with respect to the separation plate 22 are used. The (holding member) rotates in the direction of the arrow h, and after about one rotation, the state shown in FIG. In this state, the cable 10 is wound around the interference prevention members 26a and 28a. However, as shown in FIG. 6B, the cables do not interfere with each other so that smooth movement can be obtained even when the cables are rotated in reverse.

  The interference preventing members 26a and 28a serve as an interference preventing member and also serve to fix (hold) the cable to the separation plate, and serve as both the cable interference preventing means and the fixing means (holding means). Assemblability is better than the structure of FIG. In the present invention, the passage portion of the cable does not necessarily have to be completely fixed to the separation plate. Therefore, in the present specification, when the expression “fixed” is used in the embodiment, the separation is not completely fixed. The word “holding” is used together with the meaning that it includes the case where the plate is engaged or held with a certain force.

FIG. 7 shows a third embodiment. Interference prevention members 26b and 28b shown in FIG. 7C (which constitute a holding member in the same manner as described above) are fixed to the cable 10 by molding or the like at regular intervals (not shown). As shown in FIG. 3, the groove 27 provided in the interference preventing member is fitted into the slide groove 34 provided in the separation plate 20, and the interference preventing members 26b and 28b slide in the radial direction. As shown in FIG. 6 (b), the interference preventing members 26b and 28b are loosely wound with a margin of one round or more at a portion near the outer peripheral direction of the separation plate. When rotating in the direction of arrow h from the state of FIG. 6B, the interference preventing members 26b and 28b slide in the center direction (the state of FIG. 7A). amount corresponding Sly dos Ru distance, can have a large number of rotations two separate plates so it is possible to rotate more than in FIG.

FIG. 8 shows a fourth embodiment. In the state of FIG. 8C, there are two cables 10, the outer cables are long and fixed to the separation plates 20 and 22, and the inner cables are fixed a little short. That is, the two cables 10 and 10 are arranged in parallel in the radial direction inside and outside, and the length between the passage portion for the separation plate 20 and the passage portion for the separation plate 22 of the cable 10 on the outer peripheral side is the inner peripheral side. The cable 10 is attached so as to be longer than the length between the passage portion for the separation plate 20 and the passage portion for the separation plate 22. For example, when the separation plate 22 is rotated in the direction of the arrow h while the separation plate 20 is fixed, the interference preventing member 26 and the cable position 22b provided on the separation plate 22 are rotated in the direction of the arrow. It becomes the state of.

  By changing the length of multiple cables and fixing them to the separation plate in this way, multiple cables can be wound in parallel, so use multiple thin cables rather than rotating one thick cable. The space between the separation plates can be narrowed, and a thin cable is soft compared to a thick cable, so it can be bent small (wound with a small radius of curvature), and the entire apparatus can be downsized.

  There are various types of cables. For example, a stereo microphone cable has a structure in which two monaural microphone cables are combined. In this case, the cable wound around the drum 6 is a single stereo cable, but it is also possible to reduce the size by using two monaural cables as the cable 10 passing through the separation plate.

  In each of the embodiments described above, the distance between the separation plates is set such that the cable moves smoothly, and the interference prevention member is provided on the separation plate so that the cable and the cable interfere with each other. There is no effect of biting in and getting over, so there is an effect that smooth rotation can be obtained. In addition, since the distance between the separation plates can be minimized, the structure with a large number of separation plates can be made small, and since the rising portion is provided on the outer periphery of the separation plate, the cable protrudes from the outer periphery of the separation plate. There is also an effect that there is nothing.

  In addition, when the interference prevention member (holding member) is fixed to the separation plate with a structure in which the cable is sandwiched, it also has an effect that the assemblability is good because it also serves to fix the cable to the separation plate. In the structure in which the interference preventing member is movable in the radial direction of the separation plate, more cables can be accommodated, so that the number of separation plates can be reduced, and further space saving can be achieved. . In addition, when a thick cable is divided and the lengths of a plurality of thin cables are changed and fixed to the separation plates, the space between the separation plates of the thick cables becomes narrower, and there is an effect that further space saving is possible.

  FIG. 10 is a schematic longitudinal sectional view showing another embodiment of the present invention. In the following embodiments, the same reference numerals are given to the parts corresponding to the previous examples, and the description of the same parts is omitted. In this embodiment, the cable 8 is wound around the winding drum 6, and a plurality of separation plates 14-24 configured coaxially with the drum are attached to the collar 13 inside the winding drum 6.

It is configured to go. Accordingly, when the cable 8 is pulled out, the separating plate 14-24 rotates sequentially, but when the cable 8 is released, the cable 8 is wound around the winding drum 6 by the elastic restoring force of the mainspring 4x '.

FIG. 11 is a schematic partial cross-sectional view showing still another embodiment in a state where a 90-degree range around the rotation axis 5 is removed.

A small diameter pulley 4b 'is rotatably attached to the base 2, and the other end of the spring 4x' is attached to the pulley 4b ', and the spring 4x' is wound by its own elastic force. ing. The elastic restoring mechanism 4 will ', the I field with the rotary shaft 5 and the cable 8 is drawn 4x' is wound on the 'larger diameter pulley 4a drawn from' small-diameter pulley 4b. When the pulling force applied to the cable 8 is removed, the rotary shaft 5 is rotated in reverse by the elastic force of the spring 4x ′, so that the cable 8 is wound around the winding drum 6. It should be noted that the elastic restoring mechanism 4 ′ shown in FIGS. 10 and 11 is merely an example, and it is needless to say that any other elastic restoring mechanism can be used.

  11 and 12 are a longitudinal sectional view and a plan view showing still another embodiment of the present invention. In this embodiment, the base 2, the rotating shaft 5, the take-up drum 6, the separation plate 14-24, the cables 8, 10, 12 and the elastic restoring mechanism 4 ', which are substantially the same as those of the above-described embodiments, are provided. Yes.

  A drive source 51 such as a motor rotates a cylindrical drive member 53 via a drive belt 52 and the like. Two belt-like elastic belts (flexible belts, the same applies hereinafter) 55A and 55B, which are spirally accommodated in the upper and lower accommodating portions 54A and 54B, are wound around the drive member 53 in a spiral manner. In such a state, it is configured to be capable of being fed and wound. The elastic belt 55A is provided with a plurality of engagement holes (engagement structures) 55a arranged in two rows in the upper and lower portions along the extending direction, and the elastic belt 55B has the engagement holes 55a and a drive. A plurality of upper and lower rows of engaging protrusions (engaging structures) 55b that engage with a helical engaging groove 53a formed on the outer periphery of the member 53 are provided. Then, the upper engaging hole 55a of the elastic belt 55A and the lower engaging protrusion 55b of the elastic belt 55B are fitted to each other, and the lower engaging hole 55a of the elastic belt 55A and the upper portion of the elastic belt 55B are engaged. The elastic belts 55A and 55B are drawn out or retracted from the accommodating portions 54A and 54B by sliding along the engaging groove 53a in a state where the protrusions 55b are fitted to each other and moving up and down with the rotation of the driving member 53. The cylindrical body 50 including the pair of elastic belts 55A and 55B is configured to expand and contract while being bent.

  A movable device 56 is fixed to the upper portion of the cylindrical body 50, and the cable 8 led out from the cable winding device is connected to the movable device 56 through the inside of the cylindrical body 50. . The cable 12 led out from the cable winding device is connected to a fixing device 57 to be connected to the movable device 56.

  With the above configuration, the movable device 56 can be moved up and down in a state where the movable device 56 and the fixed device 57 are connected via the cables 8, 10, and 12. Here, examples of the movable device 56 include an imaging device such as a CCD camera, various sensor devices such as a microphone, various processing devices such as a watering device, and various manipulators. On the other hand, examples of the fixing device 57 include a control device, a data processing device, and a power supply device.

  In addition, although each said embodiment and Example demonstrated the cable winding apparatus which has a winding drum, this invention can be used not only for a cable winding apparatus but for various cable connection apparatuses. For example, various cable connection devices having a rotating body that rotates together with a part of the cable other than the winding drum, for example, a stage device having a rotating stage to which one end of the cable is connected as the rotating body, and one end of the cable as the rotating body Inspection device or transport device having a connected turntable, robot hand or robot device having a manipulator to which one end of a cable is connected as a rotating body, operation switch having one end of the cable connected as a rotating body, etc. It can be applied to vehicles and other various machines such as forklifts.
