An electronic apparatus has: a tray holding a communication card; a card socket accommodating the tray; an eject mechanism that ejects the tray in response to an operation of inserting a pin; a cover which is provided integrally with the tray and in which an eject hole through which the pin is inserted to operate the eject mechanism is formed; a reset switch for resetting a system in response to the operation of inserting the pin; and a reset hole into which the pin is inserted to operate the reset switch. The card socket and the reset switch are provided adjacently to a position along a first edge of a flat rectangular chassis, and the reset hole is covered by the cover while the tray is in the card socket.
