A data processing apparatus includes: a housing including an opening formed therein for accommodating a unit that has a unit side connector; an apparatus side connector that is disposed at the back of the opening so as to be seen through the opening, and is to be connected with the unit side connector; and a projection for preventing wrong operation. The projection is formed at the side of the opening and projecting inside the opening. The projection evades interference with the unit when the unit is placed in the opening in a normal posture to be inserted in the apparatus side connector, while the projection interferes with the unit when the unit is pressed toward the apparatus side connector while at least the front end of the unit is lifted.
