Abstract

An observation device according to the present invention comprises a stage on which a fluid vessel containing therein an object to be observed such as a cell or microorganism is to be placed, an observing part observing the object to be observed, a driving part performing a stage driving for moving a position of the stage with respect to the observing part, and a control part controlling the stage driving performed by the driving part. The stage driving includes a moving mode for moving the stage toward a predetermined position and a stop process mode for performing a stop process of stopping the stage at the predetermined position, and the control part performs the stop process several times in the stop process mode, and controls the stage driving so that a velocity or an acceleration of the stage driving is common among the stop processes in the stop process mode.

First claim

What is claimed is:

1. An observation device comprising:
a stage on which a fluid vessel containing therein an object to be observed, the object including a cell or microorganism which is to be placed in the fluid vessel;
an observing part observing the object to be observed;
a driving part performing a stage driving for moving a position of the stage with respect to the observing part; and
a control part controlling the stage driving performed by the driving part,
the stage driving including a moving mode for moving the stage toward a predetermined position and a stop process mode for performing a compensation control after the moving mode to thereby stop the stage at the predetermined position,
wherein the control part performs a compensation control as the stop process in the stop process mode, in the compensation control the control part configured:
to determine whether or not a driving of the driving part is stopped,
to perform a first driving and a second driving after the first driving if the driving of the driving part is stopped,
not to perform the first driving and the second driving if the driving of the driving part is not stopped,
and then to stop the stage driving,
the first driving being for changing the position of the stage with respect to the observing part in a predetermined direction in accordance with a first driving parameter which is a parameter regarding a velocity or an acceleration of the stage driving,
the second driving being for changing the position of the stage with respect to the observing part in a direction opposite to the predetermined direction in accordance with a second driving parameter which is a parameter regarding the velocity or the acceleration of the stage driving.

2. The observation device according to claim 1 , further comprising:
a memory storing information including the position of the stage used when the control part controls the stage driving,
wherein the compensation control is performed in both the stage driving for moving the stage to the predetermined position in order for the memory to store the predetermined position of the stage and the stage driving for moving the stage to the predetermined position which is stored in the memory.

3. The observation device according to claim 1 , wherein the driving part includes an X-axis driving section driving the stage in an X-axis direction and a Y-axis driving section driving the stage in a Y-axis direction which is perpendicular to the X-axis direction, and the control part performs the compensation control on the X-axis driving section and the compensation control on the Y- axis driving section when performing the stage driving in the X-axis direction or the stage driving in the Y-axis direction.

4. An observation system comprising:
the observation device according to claim 1 ;
a cabinet which accommodates therein the observing part and the stage included in the observation device, includes a putting into/taking out part putting the fluid vessel into and taking the fluid vessel out, and is sealed off from outside; and
an environment maintaining device maintaining a predetermined environment in the cabinet.

5. The observation device according to claim 1 , wherein the predetermined direction is a clockwise direction, and wherein the direction opposite to the predetermined direction is a counterclockwise direction.

6. The observation device according to claim 5 , wherein the clockwise direction and the counterclockwise direction are with respect to rotation of a gear that causes movement of the stage.

7. The observation device according to claim 5 , wherein the clockwise direction and the counterclockwise direction are with respect to rotation of a gear that causes movement of the stage.

8. The observation device according to claim 1 , wherein the predetermined direction is a counterclockwise direction, and wherein the direction opposite to the predetermined direction is a clockwise direction.

9. The observation device according to claim 1 , wherein zoom control and focus control on the stage are only performed after the driving of the driving part is determined to have stopped.

10. A computer-implemented control method of an observation device comprising a stage on which a fluid vessel containing therein an object to be observed such as a cell or microorganism is to be placed, an observing part observing the object to be observed, and a driving part performing a stage driving for moving a position of the stage with respect to the observing part,
the stage driving including a moving mode for moving the stage toward a predetermined position and a stop process mode for performing a compensation control after the moving mode to thereby stop the stage at the predetermined position, the control method of the observation device comprising the steps of:
controlling the stage driving performed by the driving part; and
performing a compensation control as the stop process in the stop process mode by a control part, in the compensation control the computer:
determining whether or not a driving of the driving part is stopped;
performing a first driving and a second driving after the first driving if the driving of the driving part is stopped,
not performing the first driving and the second driving if the driving of the driving part is not stopped,
and then stopping the stage driving,
the first driving being for changing the position of the stage with respect to the observing part in a predetermined direction in accordance with a first driving parameter which is a parameter regarding a velocity or an acceleration of the stage driving, the second driving being for changing the position of the stage with respect to the observing part in a direction opposite to the predetermined direction in accordance with a second driving parameter which is a parameter regarding the velocity or the acceleration of the stage driving.

11. The computer-implemented control method according to claim 10 , wherein the predetermined direction is a clockwise direction, and wherein the direction opposite to the predetermined direction is a counterclockwise direction.

12. The computer-implemented control method according to claim 11 , wherein the clockwise direction and the counterclockwise direction are with respect to rotation of a gear that causes movement of the stage.

13. The computer-implemented control method according to claim 10 , wherein the predetermined direction is a counterclockwise direction, and wherein the direction opposite to the predetermined direction is a clockwise direction.

14. The computer-implemented control method according to claim 13 , wherein the clockwise direction and the counterclockwise direction are with respect to rotation of a gear that causes movement of the stage.

15. The computer-implemented control method according to claim 10 , further comprising, after the driving of the driving part is stopped:
performing zoom control on the stage; and
performing focus control focus control on the stage.
