An apparatus with the additionally installable equipment. The apparatus includes an apparatus housing and an additionally installable equipment detachably attached to the apparatus housing. An inserted portion is formed to a bottom surface of the apparatus housing, and an inserting portion is formed to an upper surface of the additionally installable equipment. When the additionally installable equipment is detached from the apparatus housing upon titling the apparatus housing at a tilt angle, a summation of the tilt angle and an interference angle formed of a point where the inserted portion and the inserting portion interfere with each other is rendered less than forty five degrees. Thus, when the additionally installable equipment is detached from the apparatus housing, the additionally installable equipment can be detached from the apparatus housing without deforming the inserting portion.
