Sheet finishing apparatus, moving mechanism for same apparatus, and moving method for same apparatus

A moving mechanism of a sheet finishing apparatus comprising:

• a frame structure configured to support a machine body including a sheet finishing mechanism;
• a base provided on the frame structure;
• plural first holders respectively pivotally supported on the base and each of the plural first holders is directed downward from the base and pivotally turns around a vertical pivot;
• plural first wheels respectively pivotally supported on the plural first holders and each of the plural first wheels rotates around a horizontal axle shifted from the pivot of each first holder;
• a second holder pivotally supported on the base and is directed downward from a part of the base, the part passing through an apparatus center of the sheet finishing apparatus, and pivotally turns around a vertical pivot;
• a second wheel pivotally supported on the second holder, rotates around a horizontal axle intersecting the pivot of the second holder, and has a greater diameter than a diameter of the first wheel;
• and
• an elastic member connected between the second holder and the base, and extends and reduces a spacing between the horizontal axle of the second wheel and the base.

A moving method for a sheet finishing apparatus comprising:

• directing downward plural first holders which respectively pivotally support first wheels, each of the first wheels rotating around a horizontal axle and pivotally turning around a vertical pivot shifted from the horizontal axle, from a base of a frame structure supporting the sheet finishing apparatus, and pivotally supporting the first holders on the base;
• directing downward a second holder which pivotally supports a second wheel, the second wheel rotating around a horizontal axle and having a greater diameter than a diameter of the first wheel and
• pivotally turning around a vertical pivot intersecting the horizontal axle, from a part of the base, the part passing through an apparatus center of the sheet finishing apparatus, and pivotally supporting the second holder on the base;
• the second holder supporting the apparatus center of the sheet finishing apparatus as an elastic member connected between the second holder and the base is loaded with a weight of the sheet finishing apparatus;
• and
• the sheet finishing apparatus moving on a floor surface by a combination of the plural first wheels and the second wheel.
