  When the stocker 26 approaches the rear limit, the guide piece 43 has an inclined surface that is inclined upward and rearward on the lower surface of the inclined piece 43b, and rides on the guide roller 24. The front part of the stocker 26 is lifted, and then the horizontal surface of the lower surface of the horizontal piece 43a moves in the front-rear direction on the guide roller 24 until the stocker 26 reaches the rear limit. Has the effect of maintaining the floating state.

  That is, the guide piece 43 and the guide roller 24 guide the front part of the stocker 26 so that the caster 34 of the front part floats during the period from the position where the stocker 26 approaches the rear limit to the rear limit. Front guide means B is formed.

Next, the operation of the first embodiment will be described with reference to FIGS. 4 and 6 to 10.
When the stocker 26 is pushed into the stocker accommodating space 14 from the front, as shown in FIG. 6, the vertical roller 41 rides on the inclined surface 23b of the stopper 23, the rear part of the stocker 26 is lifted, and the rear caster 35 is moved to the floor. It is levitated from the surface 6.

  As shown in FIG. 7, when the vertical roller 41 gets over the top of the inclined surface 23 b of the stopper 23, the vertical roller 41 is supported on the horizontal piece 21 a of the guide rail 21 as shown in FIG. 8. At this time, the vertical roller 41 is positioned in the front limit where it abuts against the abutting piece 23 a of the stopper 23, and the rear caster 35 is maintained in a state of slightly floating above the floor surface 6.

  When the stocker 26 is pushed backward from this state, the vertical roller 41 rolls on the horizontal piece 21a of the guide rail 21, and the front caster 34 rolls along the floor surface 6 to 26 can move backward smoothly with the rear part slightly lifted.

  From the initial stage when the stocker 26 is pushed into the stocker accommodating space 14 from the front, the guide roller 19 is along the lower outer surface of the side plate 29 of the stocker 26, and the horizontal roller 37 is along the upper inner surface of the bracket 12, respectively. By rolling, the stocker 26 is positioned in the left-right direction, and the stocker 26 is smoothly guided in the front-rear direction.

  As shown in FIG. 9, when the stocker 26 approaches the rear limit, the lower surface of the inclined piece 43 b of the guide piece 43 rides on the guide roller 24, and until the front caster 34 floats from the floor surface 6, As shown in FIG. 10, the horizontal surface of the lower surface of the horizontal piece 43a moves backward on the guide roller 24 until the front part is lifted and then the stocker 26 reaches the rear limit. The surface is kept floating above the floor surface 6.

  At this time, the front portion of the stocker 26 is maintained in a state where the front casters 34 are lifted from the floor surface 6, so that even if the floor surface 6 is uneven, the front plate 28 is inclined by this. The front plate 28 is always held in the same state with respect to the front end surfaces of the base shelf plate 11 and the side plate 13 and can have a beautiful appearance.

  Further, when the stocker 26 is located at the rear limit as the storage position, the vertical roller 41 falls into the notch 21c, so that an appropriate resistance can be given to the forward movement of the stocker 26. Thereby, it is possible to prevent the stocker 26 from opening darkly due to an earthquake or other vibration.

  In order to open the stocker 26 from the stowed position, a hand is placed on the handle portion 27 of the front plate 28 and pulled forward. Then, the vertical roller 41 rides on the horizontal piece 21a of the guide rail 21 from the notch 21c and then rolls on the horizontal piece 21a, and the rear caster 35 floats from the floor surface 6 at the rear part of the stocker 26. In the state, move smoothly forward.

  Further, while the horizontal piece 43a and the inclined piece 43b of the guide piece 43 pass on the guide roller 24, the front part of the stocker 26 descends and the front caster 34 comes into contact with the floor, and thereafter, As the caster 34 rolls along the floor surface 6, the front portion of the stocker 26 is smoothly moved forward.

When the stocker 26 reaches the front limit, the vertical roller 41 contacts the contact surface 23a of the stopper 23, and the stocker 26 is stopped at that position.
Therefore, the stocker 26 is normally opened and closed by moving in the front-rear direction between the front limit and the rear limit in the manner as described above.

  When it is desired to take out the stocker 26 from the stocker storage space 14, as shown in FIG. 8, after moving the stocker 26 to the front limit, it moves forward while lifting the rear part of the stocker 26, as shown in FIG. Next, the vertical roller 41 is moved over the top of the stopper 23 and placed on the inclined surface 23b. Then, after the vertical roller 41 descends while rolling along the inclined surface 23b and the caster 35 at the rear part of the stocker 26 touches the floor, the stocker 26 is in a self-supporting state by the front and rear casters 34, 35. It can move freely along the floor surface 6.

As is clear from the above, in the first embodiment, when the stocker 26 is in the storage position, the stocker 26 is in a state where the caster 34 is lifted from the floor surface 6, and the rear part is provided by the rear guide means A and the front part. Since the portion is supported by the front guide means B, even if the floor surface 6 is uneven, there is no level shift between the display shelf and the stocker 26, and the appearance is always beautiful. Can be presented.
Further, when the stocker 26 is pulled slightly forward from the storage position, the caster 34 comes into contact with the floor, and the load on the front part of the stocker 26 can be supported by the caster 34. Therefore, the center of gravity of the entire display shelf when the stocker 26 is put in and out. Can be reduced.
