Memory control equipment for computers

A storage room for storing an attachment unit is provided with a plate for sheltering electrified portions inside the storage room from outside while the attachment unit is not stored in the storage room. A hook is also provided to maintain a state where the plate shelters the electrified portions. While the attachment unit is not stored in the storage room the hook protrudes into the storage room and is positioned at an area over the plate. When an external force is applied to the plate, the hook prevents the plate from being fallen down by the external force by hooking the plate thereon.

Electronic apparatus

An electronic unit having an electric connecting part connectable with a plug is accommodated in a housing of an electronic equipment so that the electronic unit can be attached to and detached from the housing. An engaging arm is rotatably mounted on one face of the electronic unit on which the electric connecting part is provided. When a plug is connected to the electric connecting part of the electronic unit, one end of the engaging arm is engaged with the engaging portion of the housing, whereby the electronic unit can be prevented from being pulled out from the housing. When the plug is detached from the electric connecting part of the electronic unit, the engaging portion of the engaging arm can be disengaged from the housing by the rotation of the engaging arm. Therefore, if the plug is detached from the electric connecting part of the electronic unit, the electronic unit can be pulled out from the housing. If the electronic equipment is arranged as above, the electronic unit can be prohibited from being pulled out from the housing of the electronic equipment under condition that the plug is connected to the electric connecting part of the electronic unit and power is supplied to the electronic unit through the plug.
