Patent ID: 8199501

Claim:
An electronic equipment comprising: air sending means for sending, at a front of an inside of a casing, air in a direction from a front surface of the casing to a back surface to cool a heat generating element; an air flow control member that is disposed in the inside of the casing and behind the air sending means and controls, by a shape, an air flow generated by an air blow of the air sending means; and an expanding member that is disposed in the inside of the casing and behind the air flow control member, includes an additional electronic circuit for an electronic circuit mounted on a main board, which are cooling targets of the air blow of the air sending means, and expands a function of the electronic circuit of the main board, wherein the expanding member has a hollow structure casing and includes the additional electronic circuit in an inside of the hollow structure casing, and the air flow control member has an opening part to allow the air flow to pass through and a blocking part to block the air flow, and supplies most of the air flow into the inside of the hollow structure casing of the expanding member by the opening part and the blocking part, the blocking part including a vent.
