PROBLEM TO BE SOLVED: To change height of the top face of a device main body easily and correctly by providing a plurality of legs on the lower part of the device main body, and enabling the contact supporting position in the vertical direction to be changed by rotational movement in the horizontal direction. SOLUTION: A plurality of legs 6 are provided so as to support a device main body 7 at its lower part. The leg 6 is provided with a receiving part 8 contacted with a floor surface, a shaft part 9 of square section, and a first contact supporting position 12 and a second contact supporting position 13 on the upper faces of a first projecting part 10 and a second projecting part 11, and a space of 50mm is provided between the supporting positions 12, 13. The supporting position 12 is joined to a second recessed part 16 in the lower part of the device main body 7, and the leg 6 is fitted so that the device main body 7 is in the height A. For changing the height of the device main body 7, by drawing out the leg 6, rotationally moving it by 90 degrees in the horizontal direction, and inserting it again, the supporting position 13 is joined to the second recessed part 16, and the leg is fitted so that the device main device is in the height B. Hence height of 50mm can be changed easily and correctly.
