Abstract

An apparatus for manipulating magnetic particles includes a latch mechanism. The latch mechanism has a pivoting part provided on a door and an engaging part provided on a main body. In the apparatus for manipulating magnetic particles, a first contact portion of a latch engages with the engaging part at a contact point in a state that the door is closed. The contact point is located more outside of the main body than the pivot axis. Accordingly, in a case where an external force is applied to the door in a direction to open the door in a state that the door is closed, a force is applied from the engaging part to the first contact portion, thereby generating a rotational force in a C direction to the pivoting part. As a result, in the state that the door is closed, it is possible to suppress the door from being opened without a manipulation by the user.

First claim

What is claimed is:

1. An apparatus for manipulating magnetic particles, comprising:
a main body that holds a tubular container in which a liquid layer is formed and which is filled with magnetic particles;
a movable magnet provided in the main body that attracts the magnetic particles in the container;
a door that is pivotally attached to the main body and pivotably moves between a closed position opposing the container and an open position separated from the container; and
a latch mechanism that keeps the door in a state of being located in the closed position, wherein
the latch mechanism has:
a pivoting part pivotable about a pivot axis; and
an engaging part that engages with the pivoting part by contacting the pivoting part at a contact position in a state that the door is located in the closed position, in which an engaging state is released when the pivoting part is pivoted in a predetermined direction about the pivot axis, wherein
the engaging part is configured, in a case where an external force to the apparatus is applied in a direction toward the open position to the door located in the closed position, a second force operates on the pivoting part at the contact position from the engaging part in a direction to pivot the pivoting part toward a side opposite to the predetermined direction, and the closed position of the door is maintained by the second force without releasing the engaging state of the engaging part,
wherein in a state that the door is located in the closed position, the pivot axis is located closer to a pivot center side of the door than the contact position in a radial direction orthogonal to both an opposing direction of the door and the main body and a vertical direction in which the pivot axis extends,
wherein the magnetic particles are attracted to the movable magnet.

2. The apparatus for manipulating magnetic particles according to claim 1 , wherein
the pivoting part is provided on the door, and
the engaging part is provided on the main body.

3. The apparatus for manipulating magnetic particles according to claim 1 , wherein
the pivoting part is provided on the main body, and
the engaging part is provided on the door.

4. The apparatus for manipulating magnetic particles according to claim 1 , wherein the latch mechanism has a biasing member that biases the pivoting part in a direction to pivot toward a side opposite to the predetermined direction.
