Electronic apparatus
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.
1. An electronic apparatus comprising:
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 that prevents wrong operation, the projection protruding from a sidewall of the opening toward inside the opening, the projection evading interference with the unit when the unit is placed in the opening in a normal posture and inserted in the apparatus side connector, the projection interfering with the unit when the unit is pressed toward the apparatus side connector, while at least an end of the unit, which is positioned opposite the unit side connector, is lifted.
2. The electronic apparatus according to claim 1 , wherein the projection is formed at each of both side walls of the opening.
3. The electronic apparatus according to claim 1 , wherein the unit has a metal frame with an interfering section that interferes with the projection when the unit is pressed against the apparatus side connector while at least a front end of the unit is lifted.
4. The electronic apparatus according to claim 1 , wherein the unit side connector has a plurality of connection pins aligned in upper and lower rows, and
the apparatus side connector has a plurality of insertion holes aligned in upper and lower rows in which the connection pins aligned in the upper and lower rows are inserted respectively.
5. The electronic apparatus according to claim 1 , wherein the unit has a built-in hard disc and accesses the hard disc.
6. The data processing apparatus according to claim 1 , further comprising:
a main unit that serves for data processing and has a keyboard at a top surface thereof, the keyboard having aligned keys for input operation; and
a display unit that has a display screen for displaying an image and is connected via a hinge to the main unit at the back of the main unit so as to be openable and closable relative to the main unit,
wherein the opening is formed in a bottom surface of the main unit.
