The electronic device includes an electronic device main body 1 and a keyboard (not shown) separate from the electronic device main body 1, and has a structure in which the keyboard is electrically connected to the electronic device main body 1 via a cable (not shown). ing. The electronic device main body 1 is a vertical thin type and includes a main body case 2. A display 3 is provided on an upper front part of the main body case 2. On the lower front side of the main body case 2, legs 4 are integrally provided to prevent the vertical thin electronic device main body 1 from falling to the front side. Body case 2
Optional board insertion slot 5 extending in the vertical direction on the right side of
Is provided. A body-side connector 6 is provided in the body case 2 behind the option board insertion slot 5.
The main body side connector 6 is attached to a predetermined location on the rear surface of the main circuit board 7 which is arranged upright in the main body case 2 on the front side of the option board insertion slot 5. An external cable side connector storage section 8 having a rear surface opened is provided at a lower portion of the main body case 2.

On the other hand, the option board 11 is provided with a handle 14 extending at right angles to the right end of a board body 13 having a protruding portion 12 on the lower right side, and provided on the rear surface of the left end (front end in the mounting direction) of the board body 13. Body connection connector 15
Is provided, and a connector 16 for connecting an external cable is provided on the rear surface of the protruding portion 12 of the board main body 13. The option board 11 is detachably mounted in the main body case 2 via the option board insertion slot 5, and the main body connection connector 15 is connected to the main body side connector 6. In this state, the handle portion 14 is along the right side surface of the main body case 2. The external cable connection connector 16 is provided in the external cable side
Is located on the near side. An external cable side connector 22 provided at one end of the external cable 21 is connected to the external cable connection connector 16. The external cable side connector 22 is housed in the external cable side connector housing section 6 from the rear side of the main body case 2. Also,
Although not shown, a main body side connector for connecting the main circuit board 7 to a power source, a printer, or the like is provided at a lower portion of a rear surface of the main circuit board 7, and these main body side connectors have one ends of various external cables. The external cable-side connectors provided in the external cable-side connector are connected to each other.

As described above, in this electronic device, the option board 11 is provided with the connector 15 for connecting the main body at the front end in the mounting direction and the connector 16 for connecting the external cable on the rear surface. While the mounting direction of the option board 11 is the left-right direction, the connection direction of the external cable side connector 32 is different from the front-back direction. Therefore, even if the external cable is pulled by mistake, the external cable side connector 32 does not come off from the external cable connection connector 16 and the main body connection connector 15 does not come off from the main body side connector 6, so that the option board 11 is not connected.
