Driving apparatus with swinging linear motion mechanism

A driving apparatus comprising:

• a first driving device;
• and
• a second driving device configured in a same manner as the first driving device and disposed symmetrically with the first driving device with regard to a central plane,
• each of the first driving device and the second driving device comprising:
• a housing;
• a first driving body supported in the housing so as to be rotatable around a first central axis;
• an eccentric driving body provided in the first driving body to be rotatable around a second central axis parallel to the first central axis;
• a first pivot provided at one end of the eccentric driving body in an axis direction and eccentrically to the second central axis and extending parallel to the second central axis;
• a second pivot provided at another end of the eccentric driving body in the axis direction and eccentrically to the second central axis and extending parallel to the second central axis;
• a first moving body rotatably coupled to the first pivot and linearly movable along a third central axis orthogonal to the first central axis;
• a first guide body which guides movement of the first moving body along the third central axis;
• and
• a second guide body which guides the second pivot such that the second pivot is linearly movable in a first direction orthogonal to the first central axis, and wherein
• the first driving device and the second driving device comprise a coupling synchronization mechanism which rotates the first driving body of the first driving device and the first driving body of the second driving device in opposite directions in synchronization with each other.
