Abstract
A carrier conveying apparatus comprises a first carrier rest for placing carriers thereon, a second carrier rest to which the carriers are conveyed, a carrier holding member for holding a plurality of carriers at a time from below, a liftably moving mechanism for liftably moving the carrier holding member and a horizontally moving mechanism provided over a distance from below the first carrier rest to a position below the second carrier rest to horizontally move the carrier holding member and liftably moving mechanism. The liftably moving mechanism lifts the carrier holding member from below the first carrier rest and hence lifts the carriers placed on the first carrier rest in a manner to hold them by the carrier holding member. Then the horizontally moving means horizontally moves the carrier holding member and liftably moving mechanism to a position above the second carrier rest. Then the liftably moving mechanism lowers the carrier holding member to place the carriers on the second carrier rest.
