The third arm is also pivotably connected to a fifth arm which is also pivotably connected to a seventh arm which has a holding portion for an object to be conveyed. The conveying arm also includes a second pivotable shaft connected to a second arm which is also pivotably connected to a fourth arm having an intermediate pivotable portion.
