Automatic analysis device

An automatic analysis device comprising:

• a housing that houses an analysis device;
• a work surface that is an upper surface of the housing;
• a cover that covers the work surface and is axially supported to be rotatable about a support shaft between a closing position and an upwardly open opening position, the support shaft being provided on one side of the housing;
• and
• closing means for inhibiting the cover from being opened at the closing position,
• wherein the closing means includes:
• a protrusion portion that protrudes rearward from a front surface of the cover,
• a locking lever that is axially supported to be rotatable about a rotating support shaft and inhibits the cover from being opened by rotating in a direction from the work surface toward the protrusion portion to cause an engagement portion to engage with the protrusion portion, and
• driving means for driving the locking lever,
• wherein in a state in which the driving means induces the engagement portion to disengage the protrusion portion, an upper surface of the locking lever is flush with the work surface, and
• wherein in a state in which the driving means induces the engagement portion to engage the protrusion portion, the locking lever inhibits the cover from being opened by being in a raised state to engage with the protrusion portion.
