A controller in which a dead space for wiring is reduced, its input-and-output response time is shortened, and miniaturization and cost reduction is ensured. A RS-232 connector connection unit (6) and a peripheral connector connection unit (7) are lowered than a projection (4) provided with displays (121 to 124) so that a cable connector does not exceed the projection (4) when the connector is mounted on the connector connection units (6) and (7).
