A door locking device is applied to an electronic apparatus including a hinged door arranged in an opening portion of a casing. The door locking device includes a key cylinder and a pivot hook. When the door is closed and a movable element of the key cylinder is at a locked position, the pivot hook is caught on the casing to prevent the door from being opened. The door locking device further includes a rod member crank-coupled to the movable element of the key cylinder on an inner side of the door and configured to be displaced by interlocking with the movable element. When the door is closed and the movable element is at the locked position, a distal end (roller) of the rod member is held in contact with a rod receiving surface formed in the casing. Thus, the rod member keeps a closed state of the door.
