To prevent incorrect detection by a detection means to detect whether the plate ejection box which is attachable to and detachable from a stencil printing device body is positioned correctly or not to the predetermined location of the stencil printing device body.
This ejected plate control device 1 includes: a plate ejection box which is detachably mounted at the predetermined location of the stencil printing device body and stores the ejected plate and can discard the stored ejected plate from an outlet 21 prepared on one side surface; a compression means 40 which is attached on the stencil printing device body and compresses the ejected plate brought into the plate ejection box and then contains them in the plate ejection box; and a detection means 50 which detects whether the plate ejection box is correctly mounted or not on the predetermined location of the stencil printing device body by detecting the position of a side face with the outlet 21 of the plate ejection box. In a compression period during when the compression means 40 compresses the ejected plate, the detection means 50 does not detect whether the plate ejection box is not positioned in the predetermined location.
