Object arrangement apparatus

An object arrangement apparatus comprising:

• a first arrangement unit that translates and arranges a second object with respect to a first object, the first object having an outer periphery including a concave portion, the second object having a shape equivalent to a shape of the first object, the second object being arranged so that a portion of the second object enters the concave portion of the first object;
• a first area computing unit that computes a first area on the basis of a distance by which the second object is translated with respect, to the first object along a first direction in which the second object is translated so that the portion of the second object enters the concave portion of the first object, and a distance between one end of the first object and the other end of the first object in a first orthogonal direction orthogonal to the first direction;
• a second arrangement unit that translates and arranges the second object with respect to the first object so that the portion of the second object does not enter the concave portion of the first object;
• a second area computing unit that computes a second area on the basis of a distance by which the second object is translated with respect to the first object along a second direction in which the second object is translated so that the portion of the second object does not enter the concave portion of the first object, and a distance between one end of the first object and the other end of the first object in a second orthogonal direction orthogonal to the second direction;
• and
• an arrangement direction determining unit that determines the first direction as an object arrangement direction if the first area:
• is smaller than the second area.
