Abstract: Uneven wear causes degradation of the individual parts of a syringe pump. Specifically, a seal piece composed of a soft material is easily damaged by uneven wear. To solve this problem, an automatic analysis device has a syringe pump that feeds and aspirates a liquid into and from a dispensing unit. The syringe pump has a syringe tube that stores a liquid, a plunger that moves up and down in the syringe tube, a plunger upper pressing component that contacts the plunger, a motive force transmitting part that transmits motive force to the plunger via the plunger upper pressing component, and a plunger lower pressing component that contacts the motive force transmitting part. The plunger upper pressing component and the motive force transmitting part make point contact with each other, and the motive force transmitting part and the plunger lower pressing component make point contact with each other.

Abstract: An automatic analyzing apparatus capable of obtaining an analysis result of a specimen high in urgency in a shorter time is provided. When a first rack 50 is present in a sampling line 103 and an analysis request for a second rack higher in the degree of urgency for analysis than the first rack 50 is detected, a control unit unloads the first rack 50 onto a transport line 100 through a return line 102, allows the first rack 50 to stand by at a rack standby position 120 on a transport line 101 between a loading line 101 and the return line 102 under control, and loads the second rack from the transport line 101 onto the sampling line 103 through the loading line 101 and transports the second rack to the dispensing position 111 under control while allowing the first rack 50 to stand by.
