Abstract: The present invention provides a device for detecting an analyte in a sample, including a chamber for receiving a testing element, where the testing element has a first position and a second position in the chamber; the testing element is not in contact with a fluid sample when the testing element is located in the first position, and the testing element is in contact with a fluid sample when the testing element is located in the second position.

Abstract: A lock mechanism is provided in front of each of left and right consoles to fix the console in an optional position. Each of the lock mechanisms is provided with a lock release lever for selecting a lock state of fixing the console and a lock release state of releasing fixation of the console. Each of the lock release levers is provided to extend outward in a left-right direction from the lock mechanism. The lock state is defined by an inclined posture in which a tip end side of the lock release lever is in an oblique downward direction and the lock release state is defined by a horizontal posture in which the tip end sides of the lock release lever is rotated in an upward direction. A hand hold part is provided in front of each of the consoles and above each of the lock release levers to swing the console in the upper-lower direction in the lock release state.
