1. A detection apparatus comprising:
a main body comprising an installation part in which a cartridge housing a liquid for treating a test substance contained in a specimen is installed and a detector configured to detect the test substance treated with the liquid within the cartridge installed in the installation part;
a lid part arranged rotatably on the main body about a shaft so as to open and close the installation part;
a biasing part biasing the lid part in an opening direction; and
a plurality of regulators each generating resistance against a biasing force in the opening direction at different timing during an opening motion of the lid part, wherein
the regulators comprise a first regulator and a second regulator coupled in a shaft direction of the first regulator,
the detection apparatus further comprises a coupling part placed covering a peripheral face of the first regulator and coupling the first regulator and the second regulator with each other in the shaft direction, the coupling part fixed to the main body,
the first regulator has a base part fixed to the main body, a rotating part rotating about the shaft with respect to the base part, and a protruding part protruding radially outward from a peripheral face of the rotating part,
the second regulator has a base part fixed to the coupling part, a rotating part rotating about the shaft with respect to the base part, and a protruding part protruding radially outward from a peripheral face of the rotating part,
the lid part has a first recessed part with which the protruding part of the first regulator is engaged and a second recessed part with which the protruding part of the second regulator is engaged,
the first regulator, during an opening operation of the lid part, does not reduce an opening speed of the lid part in a state in which the protruding part of the first regulator is positioned at a circumferentially intermediate part of the first recessed part and reduces the opening speed of the lid part in a state in which the protruding part of the first regulator is in contact with a circumferential end part of the first recessed part, and
the second regulator, during the opening operation of the lid part, does not reduce the opening speed of the lid part in a state in which the protruding part of the second regulator is positioned at a circumferentially intermediate part of the second recessed part and reduces the opening speed of the lid part in a state in which the protruding part of the second regulator is in contact with a circumferential end part of the second recessed part.
