Claims

[Scope of Claim for Utility Model Registration] An agglutination reaction stage on which a blood type card is placed; a shaking mechanism for reciprocating the agglutination reaction stage around a horizontal axis; and blood and antiserum dropped onto the blood type card. a stirring rod for stirring the mixture, a stirring suction rod having a spherical part made of a water-absorbing material attached to one end of the stirring rod, and a clamp mechanism for slidably gripping and releasing the stirring rod; , a blood suction mechanism that rotates the clamp mechanism inverted around a horizontal axis to press the spherical part of the gripped stirring rod against and away from the blood type card; and a clamp mechanism that grips the stirring rod. An elevating mechanism used in a blood type agglutination reaction device, comprising: a drive section that supports a cycloid to draw a cycloid trajectory in a horizontal plane; and an elevating mechanism that moves the drive section up and down. a tilting base on which the unit is mounted and tiltably supported by a tilting shaft; a connecting rod having a base end rotatably pivoted to the tilting base; and a vicinity of the free end of the connecting rod. a forked portion provided on the forked portion; a crank cam having a crank pin that engages with the forked portion; and the connecting rod is pushed up by the crank cam to the maximum extent. and a bottom dead center limit switch that is pressed in contact with the tilting base to detect that the tilting base has descended to a horizontal position. Features: Lifting mechanism for blood type agglutination reaction equipment.
