And a screw member 36 which is mounted by being engaged with the screw. With this configuration, it is possible to adjust the vertical position by moving the vertical position of the upper support plate 40 and the lower support plate 42 with respect to the support plate fixing screw 44, and according to the dimensions of the slide member 26. Adjustment is possible.

(Function, effect)
Hereinafter, the operation and effect of the present embodiment will be described.

  When carrying out periodic maintenance / inspection (maintenance) of the hall operation panel NB, first, an operator opens the cover main body 24m and pulls out the cover main body 24m to the near side (the side to be taken out in the slide movement direction U). . As a result, the slide member 26 fixed by welding to the slide member side connecting member 24h3 slides forward. Here, since the sliding member sliding contact portion PC (hole wall portion 32w) is made of metal and the storage portion main body sliding contact portion MC (ring portion 36r) is made of resin or ceramics, the sliding movement moves smoothly and the metal The fact that the members are slid and moved is suppressed. Since the slide member 26 is made of metal and the upper support plate 40 and the lower support plate 42 are made of resin or ceramics, the slide member 26 is smoothly guided, and the occurrence of burrs during the guidance is suppressed.

  If a slide occurs during the slide movement and the slide cannot be moved smoothly, the slide is eliminated by correcting the inclination of the slide member 26, and the normality of the screw engagement state of the screw member 36 is confirmed. The vertical direction positions of the plate 40 and the lower support plate 42 are adjusted and set so that they can move smoothly.

  After the cover 24 is pulled out, the screw member 36 is removed from the storage unit main body 22, the cover 24 is removed from the storage unit main body 22, and maintenance / inspection work and repair work of the cover 24 and the landing side operation unit 28 are performed. It should be noted that even if the cover 24 is not removed, the operation can be performed without removing the cover 24 if there is no problem in the work.

  After the operation is completed, the slide member 26 is disposed between the upper support plate 40 and the lower support plate 42, the screw member 36 is inserted into the elongated hole 32 and engaged with the screw, and a force is applied to the cover body 24m to cover the cover body 24m. 24 and the slide member 26 are slid to the back side (the side to be inserted in the slide movement direction U) to reach a predetermined position, and the cover 24 is closed. Here, since the sliding member sliding contact portion PC (hole wall portion 32w) is made of metal and the storage portion main body sliding contact portion MC (ring portion 36r) is made of resin or ceramics, it is the same as when the cover 24 is pulled out to the front side. In this sliding movement, the movement is smooth, and it is suppressed that the metal members are slid as if they are slid. Since the slide member 26 is made of metal, and the upper support plate 40 and the lower support plate 42 are made of resin or ceramics, the slide member 26 is smoothly guided as in the case of pulling out the cover 24 to the front side, and the guide is set at the time of guidance. Is suppressed from occurring.

  As in the case of pulling out the cover 24, when a slide occurs during the slide movement and the smooth movement is not possible, the slide is eliminated by correcting the inclination of the slide member 26 and the screw member 36 is in the screw engagement state. The normality is confirmed, and the vertical positions of the upper support plate 40 and the lower support plate 42 are adjusted so that they can move smoothly.

  As described above, in the present embodiment, when the slide member 26 is pulled out from the storage unit main body 22, one of the slide member sliding contact portion PC and the storage unit main body sliding contact portion MC is made of metal and the other is resin or ceramics. Therefore, it is suppressed that the sliding member 26 and the accommodating part main body 22 are stuck and cannot move smoothly. That is, since it is possible to avoid the situation that the slide member 26 is moved in the slide movement direction U many times as in the past, a fault such as a ground fault across the electric wiring C occurs. The possibility of doing this can be greatly reduced, and the workability can be improved and the working time can be greatly shortened.

  In addition, the fact that the situation that occurs in the conventional manner can be suppressed can prevent the worker from being psychologically driven when there is no time and the device (the landing control panel NB) is rushed to return. There is also an effect that it can be largely suppressed.

  In the present embodiment, the slide member sliding contact portion PC is constituted by the hole wall portion 32 w of the elongated hole 32 of the slide member 26, and the storage portion main body sliding contact portion MC is constituted by the ring portion 36 r of the screw member 36. Therefore, these effects can be achieved with a slide mechanism having a simple configuration.

  In the present embodiment, an upper support plate 40 and a lower support plate 42 are provided to guide the upper and lower sides of the slide member 26 in the sliding movement direction, respectively. Then, the slide member 26 is made of metal, and the upper support plate 40 and the lower support plate 42 are made of resin or ceramics, and there is a gap between the slide member 26 and the upper support plate 40 and the lower support plate 42. It is easy to slide smoothly. This greatly contributes to reducing the gap d1 between the slide member 26 and the upper support plate 40 and the gap d2 between the slide member 26 and the lower support plate 42 as much as possible. There is also an effect that the occurrence of sticking can be greatly suppressed.

  The same effect can be obtained even when the slide member 26 is made of resin or ceramics and the ring portion 36r, the upper support plate 40, and the lower support plate 42 are made of metal.

  In the present embodiment, the slide mechanism 20 includes the adjustment structure J that adjusts the vertical position of the upper support plate 40 and the lower support plate 42. Accordingly, the vertical position of the upper support plate 40 and the lower support plate 42 can be adjusted by moving the vertical position of the upper support plate 40 and the lower support plate 42 with respect to the support plate fixing screw 44, and according to the vertical width of the slide member 26. Adjustments are possible. Here, in order to make the gaps d1 and d2 as small as possible, the support plate fixing screws 44 are preferably screws from the viewpoint of finely adjusting the vertical positions of the upper support plate 40 and the lower support plate 42. .

  In addition, the elongate long hole part 46 which comprises the adjustment structure J can also be set as the structure which inclines with respect to the vertical direction and is extended in the diagonal direction. As a result, the effect of further facilitating fine adjustment of the gaps d1 and d2 is achieved, and the effect of greatly reducing the downward force applied from the slide member 26 to the lower support plate 42 is also achieved.

  Further, in the present embodiment, the description has been given of the example in which the slide mechanism 20 is provided in the configuration in which the cover 24 forms the hall operation panel NB and the box portion 30 accommodates the hall side operation unit 28, but as shown in FIG. The same effect can be obtained when the slide mechanism is provided in a configuration in which the slide mechanism is arranged on the car K, the cover 54 exposed to the inside of the car constitutes the car operation panel, and the box portion accommodates the car side operation unit. Played. In this case, the cover 54 has a destination floor button 60 for instructing the destination floor, an opening / closing button 62 for instructing opening / closing of the door, and an electric display board 64 indicating the moving direction (upward and downward directions) of the car K on the front side. The box portion accommodates a car side operation unit electrically connected to the car operation panel.
