## Abstract

An examination pretreatment apparatus includes a moving unit configured to place a tip portion of a rod member housed in a first container in a second container different from the first container through an opening in the second container; a position detection unit configured to detect a position of the tip portion; a position correction unit configured to correct the position of the tip portion; and a control unit configured to control the position correction unit so that the tip portion is housed in the second container, based on a result of detection by the position detection unit.

## Claims

### Claim 1

An examination pretreatment apparatus comprising:
a moving unit configured to place a tip portion of a rod member housed in a first container in a second container different from the first container through an opening in the second container;
a position detection unit configured to detect a position of the tip portion;
a position correction unit configured to correct the position of the tip portion; and
a control unit configured to control the position correction unit so that the tip portion is housed in the second container, based on a result of detection by the position detection unit.

### Claim 2 (depends on 1)

The examination pretreatment apparatus according to claim 1, wherein the position detection unit detects the position of the tip portion in a plane perpendicular to an insertion direction in which the tip portion is inserted into the opening in the second container at a detection position set behind the opening along the insertion direction, and
the control unit corrects the position of the tip portion in the plane so that the tip portion is positioned inside the opening in the second container as viewed in the insertion direction, based on the result of the detection by the detection unit, and after the position is corrected, the control unit controls the position correction unit so that the tip portion is moved in the insertion direction.
