a sample dispensing probe configured to suction each sample contained in each of the transferred sample containers mounted on the target sample rack at the fixed sample dispensing position.

2. The automatic analysis apparatus according to claim 1 further including a fluid level detector configured to detect a fluid level of a sample contained in each of the plurality of second sample containers held on a plurality of target sample racks moved outside of the second sampler unit by the second moving device.

3. The automatic analysis apparatus according to claim 1 , wherein the third moving device is configured to stop the target sample rack at a suctioning position of a predetermined height when a fluid level of the target sample is detected by the fluid level detector.

4. The automatic analysis apparatus according to claim 1 , wherein the first moving device is configured to transfer the target sample rack mounted on the first sampler unit to the second sampler unit through a first lane, and to transfer the target sample rack moved in the second sampler unit to the first sampler unit through a second lane.

5. The automatic analysis apparatus according to claim 1 , wherein the first moving device is configured to transfer the target sample rack mounted on the first sampler unit to the second sampler unit through a common lane, and to transfer the target sample rack moved in the second sampler unit to the first sampler unit through the common lane.

6. The automatic analysis apparatus according to claim 1 , wherein the first sampler unit comprises a first belt configured to move the plurality of sample racks placed on a waiting area of the first belt in one direction; and a second belt connected at one edge portion of the first belt so as to successively move the target sample rack along the one direction;

wherein the second belt includes an extracting position provided in an interruption area of the second belt;

whereby the first belt is configured to stop movement of the plurality of sample racks when the target sample rack is placed on the interruption area of the second belt, and to restart movement of the plurality of sample racks when the target sample rack is transferred to the second sampler unit through the extracting position by the first moving device.

7. The automatic analysis apparatus according to claim 1 , wherein the first sampler unit includes a free-space that operates as an urgent rack introduction entrance, wherein the free-space can be used to place an urgent target sample container containing an urgent target sample or an urgent target sample rack holding the urgent target sample container.

8. The automatic analysis apparatus according to claim 1 , wherein the second sampler unit is constructed so as that an urgent target sample container containing an urgent target sample or an urgent target sample rack holding the urgent target sample container can be directly provided in the second sampler unit.

9. An automatic analysis apparatus comprising:

a rack sampler unit configured to movably mount a plurality of first sample racks, each holding a plurality of sample containers;

a disk sampler unit configured to movably mount a plurality of second sample racks different from the plurality of first sample racks mounted on the first sampler unit;

a first moving device configured to draw a target sample rack among the plurality of first sample racks mounted on the rack sampler unit into the disk sampler unit;

a second moving device configured to set each of a plurality of target containers mounted on the target sampler rack drawn into the disk sampler unit at a fixed sample dispensing position by moving the target sample rack along in an upper direction from a surface of the disk sampler unit, the second moving device including a third moving device configured to move the target sample rack placed at an extracting position of the disk sampler unit in a horizontal rack moving direction to a fixed sample dispensing position and a fourth moving device configured to move the target sample rack moved by the third moving device in up-and-down directions at the fixed sample dispensing position; and

a sample dispensing probe configured to suction each sample contained in each of the target containers at the fixed sample dispensing position.

10. The automatic analysis apparatus according to claim 9 , wherein the second moving device moves the target sample rack in a vertical direction in order to set each of the plurality of target containers mounted on the target sample rack at the fixed sample dispensing position.

11. The automatic analysis apparatus according to claim 9 further including

a first container reader configured to read each identification data of the plurality sample containers held by the rack sampler unit;

a second container reader configured to read each identification data of the plurality of sample containers held on the target sample rack drawn into the disk sampler unit;

whereby the target sample container can be directly set into the disk sampler unit during a period when the sample dispensing probe is stopping a dispensing operation.

12. The automatic analysis apparatus according to claim 9 wherein the rack sampler unit includes a free-space that operates as an urgent introduction entrance, wherein the free-space can be used to place an urgent target sample container containing an urgent sample or an urgent target sample rack holding the urgent target sample container.
