Abstract

An analyzer comprises a container supplying unit which supplies a container, an agitating unit which agitates liquid in the container, and a measurement unit which performs a measurement using the liquid agitated by the agitating unit. The agitating unit comprises a base which is configured to move relative to the container supplying unit, a driving source which is mounted on the base, a container catcher which is configured to catch the container at one side, a transmitting member which transmits the power of the driving source to the other end side of the container catcher, and a supporting member which supports the container catcher at a position between one end and the other end of the container catcher.

First claim

What is claimed is:

1. An analyzer comprising:
a container storage area;
an agitator configured to agitate liquid in a container; and
a measurement unit configured to perform a measurement using the liquid agitated by the agitator,
wherein the agitator is movable between the container storage area and the measurement unit, and comprises:
a motor;
a container catcher; and
a rotating shaft comprising an eccentric part formed by a bend in the rotating shaft which rotates in conjunction with the motor and is coupled to the container catcher by a supporting member.

2. The analyzer of claim 1 , wherein the container catcher is movable to a container catching position adjacent to the container storage area.

3. The analyzer of claim 1 , wherein the eccentric part supports the container catcher when the container catcher translates along the eccentric part, and
the motor is configured to oscillate the rotating shaft.

4. The analyzer of claim 3 , wherein the container catcher is supported by the rotating shaft, and the container catcher is movable along the eccentric part.

5. The analyzer of claim 3 , wherein the rotating shaft is inserted into a through hole or a concavity defined by the container catcher; and
the container catcher is configured to oscillate when the eccentric part is in contact with the inner wall of the through hole or the concavity in conjunction with the rotating shaft.

6. The analyzer of claim 3 , wherein the eccentric part comprises an inclined portion inclined relative to a center of rotation of the rotating shaft.

7. The analyzer of claim 3 , wherein the eccentric part comprises a linear portion parallel to a center of rotation of the rotating shaft.

8. The analyzer of claim 1 , wherein the supporting member is an elastic member.

9. The analyzer of claim 1 , wherein the agitator further comprises:
a pulley connected to the rotating shaft; and
a transmission belt connected to the motor and the pulley.

10. The analyzer of claim 1 further comprising:
a sample dispenser; and
a reagent dispenser.

11. An analyzer comprising:
a container storage area;
an agitator configured to agitate liquid in a container; and
a measurement unit configured to perform a measurement using the liquid agitated by the agitator,
wherein the agitating unit is movable between the container storage area and the measurement unit, and comprises:
a motor;
a container catcher; and
a rotating shaft comprising an eccentric part formed by a bend in the rotating shaft which rotates in conjunction with the motor and is coupled to the container catcher by a supporting member,

wherein the rotating shaft is rotated by the motor to oscillate the container.

12. The agitating apparatus of claim 11 , wherein
the eccentric part eccentrically oscillates in conjunction with the motor.

13. The agitating apparatus of claim 11 , further comprising a flexible supporting member connecting the rotating shaft to the container catcher.
