Abstract
A sample rack recovery method after an accidental interruption of operation of a sample rack manipulation device (10), a sample rack manipulation device (10) capable of performing the method, an automatic detection system (1) comprising the device (10), and a computer-readable medium in which a program for executing the method is stored. The device (10) comprises a conveying device (103) adapted to move in a transport area (TB) to convey a sample rack (30) between a loading/unloading area (TA), sampling areas (TD, TE) and a buffer area (TC). The method comprises: a conveying device detection step of detecting the state of a conveying device (103); a sample rack detection step of detecting the position of a sample rack (30) in a sample rack manipulation device (10); and a sample rack recovery step of conveying the sample rack (30) to a loading/unloading area (TA) by the conveying device (103) according to the detection results of the conveying device (103) and the sample rack (30).
