FIG. 1 is a sectional view of a positioning mechanism portion in an upper and lower unit device of an embodiment according to the present invention. Here, the upper and lower unit devices include a copying machine, a printer, or a facsimile as an upper unit (not shown), a base for mounting the upper unit as a lower unit 2 (see FIG. 3), and an upper unit as a lower unit. When it is placed on the top, it is composed of a positioning mechanism part for positioning, and the structure of the positioning mechanism part is as follows. That is, the column-shaped base rubber 3 having a circular recess 4 is attached to the bottom plate 10 of the upper unit by the bolt 31. On the top plate 20 of the lower unit for mounting the upper unit, a positioning pin 6 is caulked at a position corresponding to the recess 4 of the leg base rubber 3. For example, as shown in FIG. 2A, four positioning pins 6 are attached to the top plate 20 of the lower unit 2. As shown in FIG. 2B or FIG. 3, casters 25 with stoppers for moving and fixing the lower unit 2 are attached to the four corners of the bottom of the lower unit 2.

When the upper unit such as a copying machine is placed on the lower unit 2 in the upper and lower unit device having the above-described configuration, the caster 25 of the lower unit 2 is fixed by the stopper, and the leg base rubber of the upper unit is fixed. The position of the recessed portion 4 of the lower unit 2 is aligned with the position of the positioning pin 6 of the lower unit 2, and the upper unit is lowered onto the top plate 20 of the lower unit 2 so that the positioning pin 6 enters the recessed portion 4. Then, the bottom portion of the leg base rubber 3 abuts against and is supported by the top plate 20, and the upper unit is positioned at the same time.
