CENTRIFUGE
First Claim
1. A centrifuge, comprising:
- a housing;
a rotor which is rotatable and to which a sample vessel containing a sample therein is attached;
a rotation room chamber which defines a rotation room that is provided within the housing and houses the rotor therein;
a lid capable of opening and closing the rotation room selectively;
a locking mechanism which is configured by an engaging portion which is provided at one of the housing and the lid in order to lock the lid in a closed state and an engaged portion which is provided at the other of the housing and the lid and with which the engaging portion engages;
an engaging portion driving mechanism which includes a driving portion having a driving shaft portion being driven and rotated and a link mechanism which converts a rotary movement of the driving shaft portion into a reciprocal movement and is coupled to the engaging portion; and
a detection portion which detects that the engaging portion moves to a position where the engaging portion engages with the engaged portion in a closed state of the lid, whereinthe detection portion includes a detected member which is fixed to the driving shaft portion and has a concavo-convex outer peripheral surface and at least one sensors for detecting a concave portion or a convex portion of the detected member, the engaging portion driving mechanism moves in an interlocked manner with a rotation of the detected member, and positions of the concave portion and the convex portion correspond to a position where the engaging portion engages with the engaged portion.

Abstract
A centrifuge includes: a rotation room chamber for defining a rotation room; a lid for closing the rotation room; a locking mechanism configured by a hook for locking the lid in a closed state; a hook catch; a driving mechanism having a link mechanism which converts the rotary movement of the driving shaft portion into a reciprocal movement; and a detection portion for detecting the engagement of the hook with the hook catch in the closed state of the lid. The detection portion includes a disc member fixed to the driving shaft portion and has a concavo-convex outer peripheral surface and sensors for detecting the concave and convex portions. The driving mechanism moves in an interlocked manner with the rotation of the disc member. The positions of the concave and convex portions of the disc member correspond to the position where the hook engages.
