PROBLEM TO BE SOLVED: To provide a syringe inspection device with high measurement accuracy. SOLUTION: In order to measure the amount of liquid sucked and discharged by using a syringe S having a cylinder 1 and a plunger 2, a cylinder receiving portion 3 for receiving the cylinder 1 and a position deciding portion 32 in contact with a flange 13, A measuring unit 41 that measures the position of the measuring point 21 provided on a part of the plunger 2, and position information obtained by setting the plunger 2 at the first position P1 and the second position P2 with respect to the cylindrical body 1, And a calculation unit 42 that stores in advance the reference volume Vα of the storage chamber R defined by the first position P1 and the second position P2 as basic information, when measuring the liquid intake / exhaust amount. , Two different positions before and after the operation of the plunger 2 are measured by the measuring unit 41 to calculate the calculation moving distance of the plunger 2, and the calculating unit 42 causes the liquid by the syringe S to be calculated based on the calculation moving distance and the basic information. Syringe inspector to calculate the intake and exhaust amount of[Selection diagram] Figure 2【課題】測定精度の高いシリンジ鑑査器を提供する。【解決手段】筒体１とプランジャ２を有するシリンジＳを用いて液体の吸排量を測定するべく、筒体１を受ける筒体受部３と、フランジ１３に当接する位置決定部３２と、プランジャ２の一部に設けた測定点２１の位置を計測する計測部４１と、プランジャ２を筒体１に対して第１位置Ｐ１と第２位置Ｐ２とに設定することで得られる位置情報、および、第１位置Ｐ１と第２位置Ｐ２とで規定される貯留室Ｒの基準容積Ｖαを基本情報として予め記憶している演算部４２と、を備え、液体の吸排量を測定する際に、プランジャ２の操作前後の異なる二つの位置を計測部４１により計測してプランジャ２の演算用移動距離を算出し、演算用移動距離と基本情報とに基いて、演算部４２がシリンジＳによる液体の吸排量を算出するシリンジ鑑査器。【選択図】図２
