Abstract: [Problem] To provide a plasma (or serum) separation apparatus and a plasma (or serum) separation method that enable quick, reliable, and low-cost separation of plasma from blood, even a minute amount of blood, at any place, without using a centrifuge separator, a pressurization/suction pump, or the like. [Solution] A plasma separation apparatus comprises a blood separation part having a blood separation member, and a plasma collection part having a plasma collection member, wherein the blood separation member is mounted on a hydrophobic pedestal and includes a blood receiving area and a plasma separation area that is connected to the plasma collection part, and the plasma separation part has the cross-sectional area thereof gradually decreasing toward the plasma collection part. Here, “plasma” means “plasma or serum.

Abstract: According to an aspect of the invention, an image forming apparatus includes an apparatus body, a sound absorbing device utilizing a Helmholtz resonator, and a hinged exterior cover operable to open and close relative to the apparatus body. The hinged exterior cover is a hinged cover configured to pivot about a pivot shaft arranged at a lower end portion of the hinged exterior cover. At least a part of the hinged exterior cover has a multiplex structure made by overlaying a plurality of plate-like members on one another. The sound absorbing device is formed by utilizing space between two plate-like members of the plurality of plate-like members making up the multiplex structure as a cavity of the Helmholtz resonator.
