Abstract: A plate transport device includes a main body, first and second moving members and first and second elastic members. The main body has an intermediate supporter. The first and second moving members have first and second supporters, respectively. The first and second moving members are supported to be movable in a first direction with respect to the main body. The first elastic member is provided between the intermediate supporter and the first supporter, and supplies a first biasing force directed toward the intermediate supporter in the first direction to the first moving member. The second elastic member is provided between the intermediate supporter and the second supporter, and supplies a second biasing force, which is directed toward the intermediate supporter in the first direction and opposite to the direction in which the first biasing force is directed, to the second moving member.

Abstract: A circulation device causes gas to circulate between a sample storage space and a temperature adjustment space through the first and second opening regions in a separating member. A temperature of gas flowing in the temperature adjustment space is adjusted by a heat exchanger, so that the temperature of gas surrounding a sample in the sample storage space is adjusted. The separating member further has first and second unit regions. The second opening region includes a first portion located in the first unit region and a second portion located in the second unit region. The shortest distance between the first portion and the first opening region is larger than the shortest distance between the second portion and the first opening region, and an aperture ratio of the first portion in the first unit region is larger than an aperture ratio of the second portion in the second unit region.

Abstract: An automatic dispensing device is provided with a sample container holder having a plurality of recesses, each of the recessed being configured to accommodate a sample container, a biasing member provided in each of the plurality of recesses, the biasing member being configured to bias the sample container accommodated in the recess upward, and a liquid dispensing mechanism having a discharge pipe for discharging a liquid from a tip end, the liquid dispensing mechanism being configured to discharge the liquid in a state in which the tip end of the discharge pipe is pressed against an inner part of the sample container at a predetermined dispensing target position from above.

Abstract: A device includes a sample rack having a mounting region for mounting a sample plate that holds a sample, a housing in which a temperature adjustment space for adjusting a temperature of the sample plate mounted on the sample rack while accommodating the sample rack inside is provided therein, and the housing having, in a lateral surface, a rack insertion opening through which the sample rack is inserted into the temperature adjustment space; and an air temperature adjustment part having an air intake port for taking in air in the temperature adjustment space, a temperature adjustment element for cooling or heating air taken in from the air intake portion, and an outlet for blowing out air cooled or heated by the temperature adjustment element.

Abstract: To suppress generation of dew condensation in temperature control space when heating temperature control is performed. In an apparatus, an air temperature control part for cooling or heating air in temperature control space has a first temperature control element for performing at least cooling of air, and a second temperature control element for performing at least heating of air downstream of the first temperature control element. In this manner, when heating temperature control is performed, cooling and dehumidification of air taken in from an air intake portion can be performed by the first temperature control element, and then heating of the dehumidified air can be performed by the second temperature control element.

Abstract: An electrophoresis apparatus includes: a sample plate including a sample receptacle; a protective sheet; a rack that supports the sample plate; a cover mounted on the protective sheet; a rack receiving mechanism that receives the rack; a punch pin; a dispensing probe; and a chip holder, and the rack receiving mechanism includes: a rack holder that removably holds the rack; and an urging portion that urges the cover toward the sample plate while the rack is held by the rack holder.

Abstract: To suppress inflow of external air through a rack insertion opening while a sample rack is pulled out. An apparatus includes a housing, a temperature control space, and an air temperature control part. The housing has the rack insertion opening on one side surface for putting in and taking out the sample rack. The air temperature control part has an air intake portion for intake of air in the temperature control space, a fan for blowing air taken in from the air intake portion toward the sample rack accommodated in the temperature control space, and a cooling element provided to cool the air on a path of air taken in from the air intake portion. The air temperature control part is configured to reduce an amount of air flowing near the rack insertion opening while the sample rack is pulled out from the temperature control space as compared to while the sample rack is accommodated in the temperature control space, so as to suppress inflow of air through the rack insertion opening.

Abstract: A seat has a backrest and a housing space to house a movable tray table in the backrest. The housing space is accessible from the posterior surface of the seat. The movable tray table is movable between a state of nonuse and a state of use. Advertising material is located in the housing space of the backrest and is viewable when the movable tray table is in a state of use by a person facing the posterior surface of the seat. The advertising material is viewable when the movable tray table is in a state of use and is not viewable and inaccessible when the movable tray table is in a state of nonuse.
