The invention provides a self-service terminal with an adjustable medium outlet. The self-service terminal comprises a function module, a door plate and an adjusting mechanism, wherein the function module is provided with a medium outlet/inlet part; the door plate is mounted on a machine body of the self-service terminal, and is provided with an opening which is matched with the shape of the medium outlet/inlet part and is larger than the medium outlet/inlet part; the adjusting mechanism comprises an adjusting plate with the periphery outline larger than the opening; the adjusting plate is provided with a medium outlet/inlet with the size and shape which are consistent to the size and shape of the medium outlet/inlet part; the end part of the medium outlet/inlet part sequentially penetrates through the medium outlet/inlet and the opening and stretches out of the outer side of the door plate. With the adoption of the technical scheme, the adjusting plate which can be adjusted is additionally arranged and a two-dimensional direction adjustable manner is used for making up machining deviation or deformation deviation, so that the medium outlet/inlet part of the function module and the opening of the door plate can be matched better, the machining precision requirements of the door plat of the terminal are reduced, and the self-service terminal is more convenient to mount.
