The present invention suppresses incorrect measurement when measuring a pressing load. A load measurement device (81) is equipped with a load sensor (95), a data logger (97), and a measurement start switch (99), which are provided inside a housing (83). The load sensor (95) outputs a detection voltage (V2) corresponding to the size of a pressing load to the data logger (97), when a suction nozzleof a mounting device presses down on a switch (95A). The data logger (97) records the detection voltage (V2) for only a prescribed interval from the timing at which a high-level recording start signal(S2) is inputted from the measurement start switch (99). As a result, the data logger (97) does not store the detection voltage (V2) during the interval until the high-level recording start signal (S2) is inputted from the measurement start switch (99), and consequently, does not incorrectly store vibrations and the like during transport as a load. 本发明抑制了按压载荷的计测中的误计测。载荷计测装置(81)在框体(83)上具备载荷传感器(95)、数据记录器(97)及计测开始开关(99)。载荷传感
