    Abstract: Buttons (41A, 41B) have a button moving part (42) disposed in front of a circuit board (51) and allowed to move in a front-back direction, and guided parts (42e) moving in conjunction with the button moving part (42). The buttons (41A, 41B) cause the button moving part (42) to operate a switch (52) of the circuit board (51). Guide parts (21E, 21F) are disposed along the guided parts (42e) and restrict the direction in which the button moving part (42) moves. The guide parts (21E, 21F) and the guided parts (42e) have portions located back of a front surface (51a) of the circuit board (51). This structure effectively prevents the buttons from tilting when they are operated.

    Abstract: Not only cooling performance for an integrated circuit such as a CPU but also cooling performance for a power supply unit is improved. An electronic apparatus (1) includes a first heat sink (71) and a power supply unit (60) including a power supply unit case (61) having an intake air wall (61a) in which a plurality of air intake holes (61b) are formed. The intake air wall (61b) is located in front of the first heat sink (71). The intake air wall (61b) has an external surface being inclined with respect to both a front-rear direction and a left-right direction and facing the first heat sink (71). A cooling fan (5) is disposed to feed air toward the intake air wall (61a).
