FIG. 4 is a side sectional view showing an example of the use of the conventional device.

In Fig. 3, reference numeral 1 denotes a suspension member similar to that used for extracting desks, and the left and right sides of a lower board 2, which has a substantially rectangular planar shape, are attached to the slider. ing. The suspension member 1 is attached, for example, to the leg member or sleeve of a reception counter as shown in FIG. 3, and supports the lower board 2 so as to be movable forward and backward with respect to the inside of the counter.

In the previously proposed device, as shown in FIG. 4, link members are provided on the left and right sides of the upper surface of the lower substrate 2 so as to form a substantially doglegged (or inverted doglegged) shape on the sides. 3a is attached to the side surfaces of the upper and lower substrates 2 and 4 by shafts 3b, 3c, and 3d, and an elevating mechanism 3 is provided with parallel links. That is, the upper board 4 is attached to the upper end of each upper link member 3a by a shaft 3d.
Further, a lower board 2 is attached to the lower end of the lower link member 3a by a shaft 3b, so that the upper board 4 can move up and down with respect to the lower board 2. Note that the upper substrate 4 has the same planar shape as the lower substrate 2.

1a and 3a are formed into connecting links having a substantially Y-shape (or inverted Y-shape) on the side.

The above-mentioned connecting links are connected by connecting rods 5a, 5a at the shaft 3c on the left and right sides of the upper and lower substrates 4, 2, and a slider member 5b and a nut member 5c are connected at the intermediate part of the connecting rods 5a, 5a.
It is substantially the same as that shown in FIG. 4 in that a threaded rod member 5d is inserted into both members 5b and 5c.

Therefore, in this mechanism, when the threaded rod member 5d is rotated in the forward or reverse direction, each link 3a is aligned with the shaft 3c, 3d.
The point that the link 31a changes its posture at the shafts 3b and 3c is the same as the mechanism shown in FIG. The upper substrate 4 is restrained and supported, and is also sandwiched and guided by the guide sides 4c, 2c that serve as guide portions of the roller 31c, and the surfaces of the upper and lower substrates 4, 2, so that the upper substrate 4 can be raised and lowered smoothly, and there is no wobbling.
