Abstract: A connector is mounted on a printed circuit board in an enclosure. A member is interposed between the enclosure and the printed circuit board so as to hold the printed circuit board on the enclosure. The member allows change in the attitude of the printed circuit board relative to the enclosure. When the connector is coupled to the other connector, the connector receives a force from the other connector in the electronic apparatus. The force induces the change in the attitude of the connector and the printed circuit board. The change in the attitude in this manner enables consumption of the energy of the force within the member. Generation of stress can be suppressed in a bonding member such as a solder coupling the connector with the printed circuit board, for example. Generation of cracks can be prevented in the solder. Shockproof is improved for the connector.
