PROBLEM TO BE SOLVED: To solve such a problem that, in conventional electronic apparatuses, it is impossible to operate electrically without securing a connection between a motherboard and an option board and therefore, both boards are integrally fixed to a main chassis with their connection retained, which, as the main chassis is large, causes the handling during transportation or an inspection to be hard.SOLUTION: The electronic apparatus includes: a main chassis 1 as an external housing; a motherboard 3 as a first substrate on which electronic components are mounted; an option board 4 as a second substrate that is electrically connected to the electronic components mounted on the motherboard 3; and a sub chassis 2 that positions and retains the motherboard 3 and the option board 4 at prescribed positions and that is fixed to the main chassis 1. |
