The cover is pivotable around a first pivot axis located nearer its lower end portion than to its upper end portion to cover or expose the first opening. The tray is pivotable around a second pivot axis between an accommodated position to cover the second opening and a use position to expose the second opening. A lower end portion of the tray is disposed below the second pivot axis. The engaging mechanism is configured to engage the tray in the accommodated position with the cover. The elastic member is configured to press the lower end portion of the tray such that the tray moves from the accommodated position toward the use position.
