Abstract: A lifter mechanism includes: a first lifter; a second lifter; a first biasing member that biases the second lifter from a second lower limit position toward a second upper limit position; a locking lever that is displaced between a locked position in which the locking lever locks the second lifter in the second lower limit position and a released position in which the locking lever releases the lock of the second lifter from the second lower limit position; a second biasing member that biases the locking lever from the locked position toward the released position; a holding member that holds the locking lever in the locked position; and a queueing lever that pushes down the second lifter from the second upper limit position to the second lower limit position.
