Abstract: A stencil disposal box is detachably provided to a stencil printing machine main body, and used stencil sheets are stored therein when the stencil disposal box is mounted to the stencil printing machine main body. An opening, through which a stencil sheet is conveyed, is formed on the stencil disposal box. The stencil disposal box includes a stencil disposal box main body for storing the conveyed stencil sheets, a sweeping member rotatively provided so as to move between an innermost position approximately adjacent to an inner surface of the stencil disposal box main body and a sweeping position located more adjacently to the opening side than the innermost position, and an operation lever portion, which can operate the movement of the sweeping member. This operation lever portion can be operated while gripping a handle portion.
