A container position detecting device (20) comprises: a detection light emitting unit (25) that emits detection light (L) from above so as to intersect the top edge (E) of an already-placed container (C2) that is already placed in a container yard (G); a first imaging unit (27) that detects first detection light (L1) shining on a suspended container (C1) and second detection light (L2) shining on the top face of the already-placed container (C2) by imaging, from diagonally above, the area illuminated by the detection light (L); and a container position determining unit (55) that finds, on the basis of the first detection light (L1) and the second detection light (L2), a container position (A) to place the container (C1). |
