A rectangular recess is formed on a front area of the case where the opening is positioned. The recess is defined by two opposed side walls, a back wall and a bottom wall. The back wall faces forward. A shutter is slidably engaged with the recess in a manner to selectively open and close the opening. The shutter is slidable in a direction parallel with the direction in which the back wall extends. The back wall of the rectangular recess has a surface which is inclined relative to the bottom wall.
