Abstract
Abstract An electronic apparatus includes a locker having a plurality of shelves, and a plurality of packages 25 are inserted in the respective shelves from the front thereof. Back boards are arranged in the locker at the rear of the shelves. A plurality of back connector boards are attached to the locker from the rear thereof. The connector of the package is plugged-in to the front the connector of the back board, and the connector of the back connector board is plugged-in to the rear connector of the back board. The back connector board also has external line connectors and an interface circuit or other circuits such as a radio interference reducing circuit and a lightning arrester.
