[Overview of Overall Configuration of Door Device 100]
First, with reference to FIGS. 1 to 3, an overview of the overall configuration of a door device 100 according to this embodiment will be described. FIG. 1 is a diagram showing a state in which the first movable column and the second movable column of this embodiment are in the closed position. FIG. 2A is a diagram showing a state in which the first movable column of this embodiment is in the open position. FIG. 2B is a diagram showing a state in which the second movable column of this embodiment is in the open position. FIG. 3 is a cross-sectional view showing a cross section taken along the III-III cutting line shown in FIG. 1, 2A and 2B show the door device 100 viewed from the left. In FIGS. 1, 2A and 2B, dashed lines below the movable column 10 represent hidden lines. In addition, in FIG. 3, a railroad vehicle T stopping on the side of the platform P is schematically shown. In FIG. 3, hatching is omitted except for the moving block BL1 and the fixed claw PN in order to avoid complication of the drawing.

The door device 100 is a device for ensuring the safety of passengers, such as preventing the passenger from falling from the platform P onto the tracks. The platform P is a boarding and alighting place provided for passengers to get on and off the railroad vehicle at a station where railroad vehicles such as trains and bullet trains running on the railroad stop.

In this embodiment, as shown in FIG. 3, the platform P has an upper surface PU on which passengers can walk, a side wall PS facing the railway vehicle T stopping on the platform P, and a side wall PS which is a part of the upper surface PU. The shape includes an overhanging portion PO that overhangs PS toward the track side. The side wall PS is a recessed wall of the platform P opposite to the track side. A space formed by the side wall PS and the projecting portion PO is preferably a space used as an evacuation site or the like.

The door device 100 includes a first movable column 10A as a first door member, a second movable column 10B as a second door member, and a telescopic fence 30. As shown in FIG. In this specification, when it is not necessary to distinguish between the first movable column 10A and the second movable column 10B, they will be simply referred to as the "movable column 10". Guides GD1 and GD2, moving blocks BL1 and BL2, and support plates C1 and C2, which will be described later, will be simply referred to as "guides GD," "moving blocks BL," and "support plates C," unless it is necessary to distinguish them. .

A plurality of the first movable columns 10A and the second movable columns 10B are alternately arranged along the edge PE of the platform P. In the example shown in FIG. 3, the edge of the overhang PO is the edge PE of the platform P. In the example shown in FIG.

The first movable column 10A and the second movable column 10B move between a closed position that restricts entry of passengers into the aisle A and an open position that allows entry of passengers into the aisle A. Passengers on the inside of the platform P than the door device 100 move when boarding a railroad vehicle stopped at the station, or passengers who get off the railroad vehicle pass through the platform P rather than the door device 100. It is the passage through which it moves inward. Note that the first movable column 10A and the second movable column 10B can move independently. That is, the first movable column 10A can move even when the second movable column 10B is stopped or moving.

FIG. 1 shows a state in which the first movable column 10A and the second movable column 10B are in the closed position. FIG. 2A shows a state in which the boarding/alighting passage A is formed by moving the first movable column 10A rearward. Moreover, FIG. 2B shows a state in which the boarding/alighting passage A is formed by moving the second movable column 10B forward. The opening width of the passageway A and the position where the passageway A is formed are variable according to the positions of the first movable column 10A and the second movable column 10B.

One end of the telescopic fence 30 is fixed to the first movable pole 10A, and the other end of the telescopic fence 30 is fixed to the second movable pole 10B. That is, the first movable column 10A and the second movable column 10B are connected via the telescopic fence 30. As shown in FIG. In this embodiment, the telescopic fence 30 includes a first telescopic bar portion 31, a second telescopic bar portion 32, a third telescopic bar portion 33, and a fourth telescopic bar portion 34, which are vertically spaced apart from each other. In addition, the telescopic fence 30 includes a connecting bar portion 35 that extends vertically and connects the first telescopic bar portion 31, the second telescopic bar portion 32, the third telescopic bar portion 33, and the fourth telescopic bar portion 34 to each other. .

Each of the telescopic bars has a different diameter and includes hollow tubular parts. Each telescopic bar is shortened by inserting a small-diameter tubular portion into a large-diameter tubular portion, and lengthened by a small-diameter tubular portion protruding from the large-diameter tubular portion. Note that FIGS. 1, 2A, and 2B show an example in which the connection bar portion 35 is connected to each cylindrical portion.

The telescopic bar portions 31, 32, 33, 34 of the telescopic fence 30 are provided so as to be telescopic according to the distance between the first movable column 10A and the second movable column 10B. In FIG. 2A, the distance between the first movable column 10A and the second movable column 10B is shortened by moving the first movable column 10A closer to the second movable column 10B. , each telescopic bar portion of the telescopic fence 30 is shown in a contracted state. On the other hand, in FIG. 2B, by moving the second movable column 10B relative to the first movable column 10A in the direction of approaching, the distance between the first movable column 10A and the second movable column 10B is increased. It shows a state in which each telescopic bar portion of the telescopic fence 30 is contracted while being shortened.

In the example shown in FIGS. 1, 2A, and 2B, the telescopic bar portions 31, 32, 33, and 34 made up of five cylindrical portions having different diameters are shown, but the present invention is not limited to this. By increasing the number of tubular portions, the length of each tubular portion can be shortened. As a result, the distance between the first movable column 10A and the second movable column 10B in the open position can be shortened, and the width of the passenger passage can be increased. On the other hand, by reducing the number of tubular parts, the structure of the telescopic fence 30 is simplified.

Further, the door device 100 includes guides GD fixed to the side walls PS of the platform P. As shown in FIG. The guide GD is a linear guide extending in the front-rear direction. As described above, the side wall PS is a wall that recedes on the opposite side of the platform P from the railroad track side, and together with the projecting portion PO constitutes an evacuation area or the like. That is, the guide GD is arranged using the space on the back side of the overhanging portion PO, which is the evacuation site or the like.

Further, as shown in FIG. 1 and the like, a plurality of guides GD are provided corresponding to each of the first movable column 10A and the second movable column 10B. Specifically, in this embodiment, as shown in FIG. 1 and the like, a guide GD1 corresponding to the first movable column 10A and a guide GD2 corresponding to the second movable column 10B are provided. The guide GD1 and the guide GD2 are parallel to each other and arranged side by side in the vertical direction. In this embodiment, the guide GD1 is fixed to the side wall PS of the platform P below the guide GD2.

Each guide GD has a length corresponding to the movable range of the corresponding first movable column 10A or second movable column 10B. Specifically, the guide GD1 has a length corresponding to the movable range of the first movable column 10A, and the guide GD2 has a length corresponding to the movable range of the second movable column 20A. Note that the movable ranges of the first movable column 10A and the second movable column 10B partially overlap. That is, the guide GD1 and the guide GD2 have lengths that partially overlap in the front-rear direction. Since the movable ranges of the first movable column 10A and the second movable column 10B partly overlap in this way, the boarding/alighting structure formed between the first movable column 10A and the second movable column 10B can be used. The width and position of the opening of the passage A are highly flexible.

The door device 100 also includes a moving block BL which is a movable body attached to the guide GD and movable along the guide GD. Specifically, the door device 100 includes a moving block BL1 attached to the guide GD1 and movable along the guide GD1, and a moving block BL2 attached to the guide GD2 and movable along the guide GD2. Note that the moving body is not limited to a block-shaped one, and any body that is attached to the guide GD and linearly moves along the guide GD may be used.

The door device 100 connects the movable column 10 and the moving block BL by extending into the gap G between the platform P and the railroad car T stopping on the side of the platform P, and is a supporting body that supports the movable column 10. Includes a support plate C. Specifically, as shown in FIG. 3, the first movable column 10A and the movable block BL1 are connected by extending to the gap G between the platform P and the railway vehicle T stopping beside the platform P, and the second It includes a support plate C1 which is a support for supporting one movable column 10A. In addition, the door device 100 connects the second movable column 10B and the moving block BL2 by extending to the gap G between the platform P and the railway vehicle stopping beside the platform P, and also the second movable column 10B. and a support plate C2, which is a supporting support. Note that the supporting member is not limited to a plate-like member, and any supporting member may be used as long as it extends into the gap G to connect the movable column 10 and the moving block BL and supports the movable column 10 .

By being supported by the support plate C1, the first movable column 10A is maintained standing on the platform P and is movable on the platform P as the moving block BL1 moves. . Similarly, the second movable column 10B is supported by the support plate C2 so that it can be kept standing on the platform P and can move on the platform P as the moving block BL2 moves. It's becoming

Further, the door device 100 has a plurality of filling members 50 capable of filling at least a part of the gap G between the platform P and the railcar T stopping on the side of the platform P. Details of the configuration of the filling member 50 will be described later.

[Details of Driving Structure of Movable Column 10]
Next, mainly with reference to FIGS. 3 and 4, the details of the structure for driving the movable column in this embodiment will be described. FIG. 4 is a perspective view of the cross-sectional view shown in FIG. 3 viewed obliquely.

As shown in FIGS. 3 and 4, the support plate C1 includes a first portion Ca extending from the exterior housing H of the first movable column 10A toward the track on the platform P, and a second portion Ca extending downward from the first portion Ca. The shape includes a portion Cb, a third portion Cc extending from the second portion Cb toward the side wall PS, and a fourth portion Cd extending downward from the third portion Cc. The first portion Ca is a portion that is not in contact with the platform P and extends along the upper surface PU of the platform P. As shown in FIG. The second portion Cb is a portion that extends into the gap G between the platform P and the railway vehicle T that stops beside the platform P.

One end of the support plate C1 is fixed to the exterior housing H of the first movable column 10A, and a moving block BL1 is attached to the other end of the support plate C1. Specifically, the first portion Ca of the support plate C1 is fixed to the exterior housing H of the first movable column 10A, and the fourth portion Cd of the support plate C1 is mounted via a vertical slider SL, which will be described later. A moving block BL1 is attached. The first portion Ca may be separate from the exterior housing H, or may be integrated therewith.

The moving block BL1 is fixed to the vertical slider SL. The fourth portion Cd of the support plate C1 is supported so as to be vertically movable with respect to the vertical slider SL. Further, as shown in FIG. 3 and the like, a damper D, which is an urging member, is provided between the third portion Cc and the vertical slider SL. The damper D is connected to the third portion Cc and the vertical slider SL so as to urge the support plate C1 to a predetermined reference position in the vertical direction. As shown in FIG. 3, the damper D preferably includes a spring. With such a configuration, for example, when the movable column 10 runs over an obstacle such as dust on the platform P, or when the movable column 10 tilts due to wind pressure, the load generated at that time is transferred to the damper D absorbed by That is, the load is suppressed from being applied to the moving block BL and the ball screw BS, which will be described later and meshes with the moving block BL.

As shown in FIGS. 3 and 4, the guide GD1 includes a bar-shaped ball screw BS extending in the front-rear direction and having a helical thread formed on its outer peripheral surface. The ball screw BS is rotated by a driving force from a motor M as a driving source. As shown in FIG. 4, the motor M is provided at one end of the guide GD and is preferably capable of supplying power to the ball screw BS.

The moving block BL1 has a nut portion N, which has a helical thread formed on its inner peripheral surface to mesh with the ball screw BS and moves in the front-rear direction as the ball screw BS rotates, and a fixed portion F which is fixed to the vertical slider SL. and a connection portion CC that connects the nut portion N and the fixed portion F. With such a configuration, the first movable column 10A connected to the moving block BL1 via the support plate C1 moves on the platform P as the moving block BL1 moves along the guide GD1 due to the rotation of the ball screw BS. Moving.

Although detailed description is omitted, the second movable column 10B is also movable on the platform P by a similar driving structure. Note that, as shown in FIG. 1 and the like, the support plate C2 connecting the second movable column 10B and the moving block BL2 is shorter in the vertical direction than the support plate C1. This is because the guide GD2 is arranged above the guide GD1.

Also, the first movable column 10A and the second movable column 10B are provided with wheels W that rotate on the platform P as they move. Thereby, the first movable column 10A and the second movable column 10B can move smoothly on the platform P. The door device 100 does not have a power source for directly rotating the wheels W. As shown in FIG. The wheels W rotate on the platform P as the movable column 10 is moved by power from the motor M that rotates the ball screw BS. In addition, one movable column 10 may have, for example, four wheels W that are adjacent to each other in the front, rear, left, and right directions.

[Compensation member 50]
5A to 5C, 6A, 6B, and 7, the filling member 50 of this embodiment will now be described. 5A to 5C are diagrams showing how the filling member moves from the filling position to the retracted position. FIG. 6A is a diagram showing the state of the filling member when the movable column is in the closed position. FIG. 6B is a diagram showing the state of the filling member when the movable column is in the open position. FIG. 7 is a top view of the door device as viewed from above, omitting the platform. In FIG. 7, the direction of movement of the first movable column 10A and the second movable column 10B is indicated by an arrow D1.

As described above, the door device 100 has the support plate C extending in the gap G between the platform P and the railcars stopping beside the platform P. As shown in FIG. Since the support plate C has a predetermined thickness, it is necessary to perform processing such as shaving the edge of the platform P in order to suppress interference with the support plate C by railroad vehicles running on the side of the platform P. . However, if the edges of the platform P are shaved, the gap G between the platform P and the railcar becomes large.

Therefore, in this embodiment, in order to fill the gap G between the platform P and the railway vehicle, a configuration is adopted in which the platform P is provided with the compensation member 50 . Further, the compensating member 50 is configured so as to avoid interference with the support plate C that moves together with the movable column 10 .

The filling member 50 is movable between a filling position within the movable area of the support plate C and filling at least a part of the gap G, and a retracted position outside the movable range of the support plate C and retreated from the filling position. is provided in Specifically, as shown in FIG. 3, the filling member 50 is rotatably supported by the platform P on the rear side of the projecting portion PO. The retracted position is a position where the filling member 50 exists on the back side of the overhanging portion PO. The filling member 50 may be directly fixed to the platform P, or may be fixed via a plate member 60 fixed to the side wall PS of the platform P as shown in FIGS. It may be indirectly fixed to the platform P. Further, as shown in FIGS. 3, 4, etc., a plurality of guides GD may be unitized in the plate member 60 to which the filling member 50 is attached. That is, the guide GD may also be indirectly fixed to the side wall PS via the plate member 60 .

The compensation member 50 includes an arm portion 50a that is rotatably supported by the platform P, and a projecting portion 50b that constitutes a part of the passageway A by projecting upward from the arm portion 50a in the state of being in the compensation position. include. The protruding portion 50b preferably has a shape in which the upper surface of the protruding portion 50b is flush with the upper surface PU of the platform P when the filling member 50 is in the filling position. However, the filling member 50 is not limited to being flush, and it is preferable that the filling member 50 has a surface that smoothly connects with the top surface PU of the platform P so that a step is not formed between the filling member 50 and the top surface PU of the platform P in the state of being in the filling position. . Specifically, for example, the filling member 50 may have an inclined surface or a curved surface that smoothly connects with the upper surface PU of the platform P. In this way, since the filling member 50 has a shape that does not form a step between at least the upper surface PU of the platform P, it is possible to suppress tripping of passengers passing through the boarding passage A.

Further, as shown in FIG. 5A and the like, the compensating member 50 includes a return spring 50S that generates a force to elastically return the compensating member 50 from the retracted position to the compensating position side. The return spring 50S is provided at the distal end of the arm portion 50a. The compensating member 50 is maintained at the compensating position by the elastic force of the return spring 50S when no external force is applied.

Further, the filling member 50 includes a movable claw 50N. The movable claw 50N has an engagement position where it is caught by a fixed claw PN, which is a fixed portion fixed to the platform P so that movement to the retracted position is restricted in a state where the compensation member 50 is at the compensation position. is movably provided between a release position where is released. The movable claw 50N is slidably provided on the arm portion 50a.

The fixed claw PN is fixed to the platform P by extending in the front-rear direction, as shown in FIG. 5A and the like. In addition, FIG. 5A shows a state in which the movable claws 50N of the compensation members 50 arranged in the front-rear direction are in the engaging position.

The filling member 50 also has a release pin 50P (release pins 50P1 and 50P2) provided on the arm portion 50a. The release pin 50P is provided on the arm portion 50a so as to be movable in accordance with the movement of the movable claw 50N.

The movable column 10 includes a release portion 11 that moves the movable claw 50N from the engagement position to the release position as it moves. As shown in FIG. 7, the release portion 11 has a shape including an inclined surface 11a and an inclined surface 11b. The inclined surface 11a and the inclined surface 11b are shaped so as to move the release pin 50P to the side opposite to the railroad track side (arrow d1 side shown in FIG. 7) by contacting the release pin 50P.

As shown in FIGS. 4, 5A, etc., the movable column 10 includes a retraction guide portion 12 that guides the compensation member 50 from the compensation position to the retraction position as it moves. The retraction guide portion 12 has a shape including an inclined surface 12S for moving the filling member 50 downward.

5A to 5C show how the movable claw 50N is released from the hooked state and the compensating member 50 moves from the compensating position to the retracted position as the movable column 10 moves.

First, as the movable column 10 moves, the inclined surface 11a of the releasing portion 11 comes into contact with the releasing pin 50P of the filling member 50. As shown in FIG. As a result, the movable claw 50N moves from the engagement position to the release position. That is, the movable claw 50N changes from the state shown in FIG. 5A to the state shown in FIG. 5B.

Further movement of the movable column 10 causes the retraction guide portion 12 to come into contact with the arm portion 50 a of the filling member 50 . As a result, the arm portion 50a is guided by the inclined surface 12S of the retraction guide portion 12 and rotates downward. As a result, the filling member 50 moves from the filling position to the retracted position. That is, the filling member 50 changes from the state shown in FIG. 5B to the state shown in FIG. 5C.

Furthermore, by moving the movable column 10, the movable claws 50N of the plurality of compensation members 50 arranged side by side along the movement direction are sequentially moved from the engagement position to the release position. Also, the plurality of filling members 50 are sequentially moved from the filling position to the retracted position.

The compensation member 50 moved to the retracted position by the retraction guide part 12 is returned to the compensation position by being biased by the return spring 50S when the retraction guide part 12 passes the compensation member 50. becomes. Therefore, as shown in FIGS. 6A and 6B, regardless of the position of the movable column 10, the filling members 50 other than the filling member 50 adjacent to the support plate C are present at the filling position. As shown in FIG. 6B, the filling member 50 constitutes part of the boarding/alighting passageway A. As shown in FIG.

5A to 5C illustrate only one side of the moving direction of the movable column 10, but the movable column 10 moves to the opposite side of the moving direction shown in FIGS. 5A to 5C. In this case, similarly, the filling member 50 is sequentially moved to the retracted position. Therefore, as shown in FIG. 7, in the movable column 10, the release portion 11 and the retraction guide portion 12 are provided on the front side and the rear side in the moving direction of the movable column 10, respectively.

Further, as shown in FIGS. 5A, 7, etc., each of the arm portions 50a of each of the filling members 50 is provided with a release pin 50P2 along with the release pin 50P1. The compensating member 50 retracted to the retracted position along with the movement of the movable column 10 is biased by the return spring 50S and returns to the compensating position as the movable column 10 passes. In this state, the movable claw 50N is at the release position. The inclined surface 11b of the release portion 11 on the rear side in the moving direction of the movable column 10 (arrow D1 in FIG. 7) contacts the release pin 50P2 when the movable claw 50N is at the release position. As a result, the release pin 50P2 moves in the direction of arrow d1 shown in FIG. As a result, the movable claw 50N moves from the released position to the engaged position.

In this manner, the release portion 11 on the front side in the movement direction of the movable column 10 moves the movable claw 50N from the engagement position to the release position by contacting either the release pin 50P1 or the release pin 50P2. Further, the release portion 11 on the rear side of the moving direction of the movable column 10 contacts the other of the release pin 50P1 and the release pin 50P2 to move the movable claw 50N from the release position to the engagement position.

In the door device 100 described above, the movable column 10 can be moved on the platform P without forming a rail or the like on the platform P. Therefore, it is not necessary to form unevenness such as grooves on the platform, and it is unnecessary to take countermeasures against tripping of passengers and intrusion of dust and rainwater caused by forming grooves and the like.

Further, in the door device 100, by providing the supplementary member 50, even when the edge of the platform P is shaved, the gap G between the platform P and the railway vehicle stopping beside the platform P can be reduced.

Further, in the door device 100, since it is not necessary to arrange a door pocket on the platform P, the width and position of the opening of the boarding/alighting passage A are highly flexible. Further, in the door device 100, the movable column 10 can be moved without mounting a driving device in the exterior housing H, so that the movable column 10 can be made relatively lightweight. Further, in the door device 100, the width in the left-right direction can be reduced because each movable column 10 can travel on the same straight travel path. That is, the overall thickness of the door device 100 can be reduced.

[First modification]
Next, a first modification of this embodiment will be described with reference to FIG. FIG. 8 is a perspective view showing a door device according to a first modified example. FIG. 8 shows a state in which a boarding/alighting passage A is formed in the door device of the first modified example. The same reference numerals are used for configurations having the same functions as the configurations described in the present embodiment, and detailed description thereof will be omitted.

In the present embodiment described above, an example in which a plurality of compensating members 50 are arranged side by side in the movable area of the support plate C has been described. In the first modified example, an example in which a compensation member 150 having a length corresponding to the width of the boarding/alighting passage A is provided in the movable area of the support plate C will be described.

As shown in FIG. 8, in the first modified example, one compensation member 150 corresponding to one boarding/alighting passage A is provided. The filling member 150 rotates between a filling position within the movable area of the support plate C and filling at least a part of the gap G, and a retracted position outside the movable range of the support plate C and retreated from the filling position. Possibly supported on platform P.

In the first modification, a power source (not shown) such as a motor that generates power for moving the filling member 150 between the filling position and the retracted position may be provided. As shown in FIG. 8, in a state in which the first movable column 10A and the second movable column 10B are positioned to form an aisle A, the compensating member 150 is in a compensating position by power from the power source. should be. On the other hand, when the first movable column 10A or the second movable column 10B moves, the filling member 150 should be at the retracted position.

In the first modified example including the filling member 150 described above, it is possible to fill the gap G with a simple configuration compared to the present embodiment including the filling member 50 that rotates with the movement of the movable column 10. becomes.

[Second modification]
Next, with reference to FIG. 9, a second modification of this embodiment will be described. FIG. 9 is a perspective view showing the appearance and partial cross-section of a door device according to a second modification. The same reference numerals are used for configurations having the same functions as the configurations described in the present embodiment, and detailed description thereof will be omitted.

In the second modified example, an example in which the door device 100 includes a compensating member 250 that linearly moves between the compensating position and the retracted position will be described. The compensation member 250 linearly moves between a compensation position within the movable area of the support plate C and filling at least a part of the gap G, and a retracted position outside the movable area of the support plate C and retracted from the compensation position. Possibly supported on platform P. It should be noted that the retracted position in the second modified example is the position on the back side of the projecting portion PO, as in the present embodiment.

In the second modification, the platform P is provided with a pushing spring 250S that elastically biases the filling member 250 . Therefore, the compensating member 250 exists at the compensating position where the gap G is filled when no external force is applied.

In the second modified example, the movable column 10 includes a push roller 13 instead of the release portion 11 and the retraction guide portion 12 described in the present embodiment. The pushing roller 13 is provided so as to come into contact with the filling member 250 and push the filling member 250 from the filling position to the retracted position as the movable column 10 moves. The pushing roller 13 includes a rotating shaft extending in the vertical direction, and is rotatable around the rotating shaft as it comes into contact with the filling member 250 . Therefore, the pressing roller 13 is not caught by the filling member 250, and the plurality of filling members 250 can be sequentially moved to the retracted position as the movable column 10 moves.

The compensating member 250 pushed into the rear side of the projecting portion PO of the platform P by the pushing roller 13 is moved to the compensating position by the biasing force of the pushing spring 250S when the pushing roller 13 passes by.

Although detailed illustration is omitted, the filling member 250 may have a structure that is flush with the upper surface PU of the platform P. As shown in FIG. That is, the compensating member 250 may have a structure in which the leading end portion of the compensating member 250 in the pushing direction protrudes upward as it moves from the retracted position to the compensating position. By adopting such a structure, it is possible to eliminate a step between the upper surface of the filling member 250 and the upper surface PU of the platform P.

In the second modification including the filling member 250 described above, it is possible to fill the gap G with a simpler configuration than in the present embodiment including the filling member 50 that is rotatably supported.

[others]
In the present embodiment and its modification, an example in which the door member is the columnar movable column 10 has been described, but the present invention is not limited to this. The door members may be plate-shaped with their moving directions being long.

Further, in the present embodiment, an example is shown in which two adjacent movable columns 10 are connected via a telescopic fence 30 including a plurality of telescopic bars, but this is not the only option. Any material can be used as long as it expands and contracts. For example, two movable columns 10 adjacent to each other may be connected by a bellows member that can expand and contract as they move.

In the present embodiment and its modification, an example in which one guide GD is provided corresponding to one movable column 10 has been described, but the present invention is not limited to this, and one movable column 10 (support plate C) may be provided.
